Section I. Notice of Funding Opportunity Description

Purpose

Through this Notice of Funding Opportunity (NOFO), the National Cancer Institute (NCI) requests applications that propose mechanistic investigations of the links between diet, lipid metabolism and tumor growth and progression. It is anticipated that this program will support fundamental studies designed to identify and define the molecular mechanisms through which lipid metabolism mediates tumor growth and progression, focusing specifically on the central role lipids play in linking diet with the biology of cancer; bridge the historically divided fields of nutrition and molecular metabolism; and stimulate research and tool development in this emerging area, which faces particular challenges because of the complexity of lipid biochemistry.

Background

Cancer cells alter the regulation of their metabolic machinery, both to meet their increased biosynthetic and bioenergetic needs and to defend against the increased levels of free radicals generated by the upregulation of oxidative metabolism. The nutrients required to support an active metabolism can be imported directly from blood plasma or tumor interstitial fluid; they can also be acquired by parasitizing the surrounding tumor microenvironment. Recent work has documented the contributions of both neighboring stromal cells, such as cancer associated adipocytes (CAAs) and cancer associated fibroblasts (CAFs), and the surrounding extracellular matrix to tumor metabolism. An equally important but less well appreciated source of fuel and biosynthetic building blocks is diet, which has been shown to impact the availability of various macronutrients in the tumor microenvironment both directly and indirectly.

Although the association between diet and cancer risk is well established, the influence of diet on tumor growth and progression is less understood. This is due partly to the challenges of defining and controlling dietary variables in patient populations, and partly to the complexity of the tumor microenvironment, which may buffer subtle changes in the concentration of some metabolites. Different dietary patterns may also have different effects depending on the tissue from which the tumor originates. For example, a high fat diet has been linked to worse outcomes for breast, colorectal, and prostate cancer patients. In support of this epidemiological evidence, studies in mouse models have found that a high fat diet significantly alters the levels of a subset of serum metabolites, and may promote tumor growth and angiogenesis even in the absence of weight gain. In contrast, a lower carbohydrate diet with a higher fat content, particularly plant-based fats, is associated with longer survival times in some prospective studies of pancreatic cancer patients.

Recent work has suggested that lipid metabolism plays a central role in connecting diet and tumor growth and progression, both by promoting cellular proliferation and by regulating anti-tumor immunity. Lipids are a structurally diverse class of macromolecule that play a variety of biological roles; they can act as signaling molecules, be oxidized to provide energy in the form of ATP, or serve as the physical building blocks of cellular membranes. Lipid metabolism is highly plastic, and is commonly deregulated in cancer cells. Multiple different dietary perturbations have now been reported to directly influence lipid metabolism in tumors. For example, in mouse models of pancreatic ductal adenocarcinoma or non-small cell lung carcinoma, caloric restriction impairs the activity of stearoyl-CoA desaturase (SCD), an enzyme that catalyzes the rate-limiting step in the synthesis of monounsaturated fatty acids, in tumor cells; the resulting imbalance in saturated and unsaturated fatty acids impairs tumor growth. Although a ketogenic diet also inhibits SCD activity in these mouse models, it supports tumor growth by increasing lipid availability and thus maintaining a balanced ratio of saturated and unsaturated fatty acids. A ketogenic diet has also been reported to raise the levels of NADH in a murine pancreatic cancer model, resulting in a sensitization of tumors to conventional cytotoxic chemotherapy. Dietary restriction of serine and glycine has been found to produce an accumulation of toxic deoxysphingolipid species that limits tumor growth in xenograft mouse models of colon cancer; sphingolipids are canonically derived from serine, which is synthesized from glycine, highlighting the need for an improved understanding of the connections between the biosynthesis of lipids and other macromolecules in cancer.

Diet has also been shown to influence tumor growth and progression through lipid-mediated effects on cells in the tumor microenvironment. In mouse models of oral squamous cell carcinoma or melanoma, short term exposure to dietary palmitic acid, a saturated fat found in meat, dairy, palm and coconut oil, induces changes in gene expression that stimulate metastasis by promoting regeneration of tumor-activated Schwann cells. A diet high in linoleic acid, a polyunsaturated fat found in vegetable oils, nuts, seeds, meat, and eggs, has also been reported to promote tumor progression in an immunocompetent mouse model of breast cancer by inducing mitochondrial dysfunction in T cells; oleic acid, which is a monounsaturated fat, did not have the same effect. The transcription factor SREBP, which is itself regulated by intracellular cholesterol levels, has been shown to promote the function and specialization of regulatory T cells by controlling multiple steps in lipid metabolism, but a detailed description of how diet-driven variations in the level and/or composition of lipids in serum or tumor interstitial fluid influence immune cell function is lacking.

Finally, diet-sensitive interactions between the tumor and the tumor microenvironment can influence tumor growth and progression in two independent but non-mutually exclusive ways. First, tumor metabolism may respond to diet-derived metabolites in a way that creates a permissive tumor microenvironment. For example, in a mouse model of colon cancer, a high fat diet causes opposing metabolic changes in tumor and CD8+ T cells; while tumor cells increase fat uptake in response to the higher levels of circulating lipids introduced by a high fat diet, CD8+T cells do not. This results in a local depletion of essential metabolites from the tumor microenvironment. Overexpressing the prolyl hydroxylase PHD3 in tumor cells reduces fatty acid uptake, increases palmitate availability in tumor interstitial fluid, and reduces tumor growth as a result of improved T cell function. Second, diet may shape the surrounding stromal environment to be pro-tumorigenic. Overnutrition leads to increased production of the adipokine chemerin, which regulates adipogenesis and adipocyte metabolism; chemerin is also overexpressed in clear cell renal carcinomas, where it maintains high levels of the transcription factor HIF2a and promotes tumor progression by suppressing fatty acid oxidation. The role chemerin plays in the progression of other cancers is not well studied, but it has been reported to directly stimulate cancer cell growth, proliferation, migration, and invasion in multiple tumor types, as well as to recruit tumor-supporting stromal cells, stimulate angiogenesis, and promote tumor suppression through immune-mediated effects.

Specific Objectives for this NOFO

This FOA, which aligns with Goal 4 of the recent NIH Strategic Plan for Nutrition Research, will provide support for mechanistic investigations of the links between diet, lipid metabolism, and tumor growth and progression. Studies that investigate high-fat, ketogenic diets are of particular interest since the limited data that are currently available indicate they can produce highly dichotomous effects on tumor progression, depending on tumor type and the presence or absence of specific driver mutations. Mechanistic studies of dietary manipulations that perturb cancer cell metabolism in the absence of weight gain or overnutrition are also of particular interest. Addressing these and other relevant problems will improve our understanding of the biology that drives tumor growth and progression, and may inform the future development of novel therapeutic approaches. However, it should be noted that for this NOFO, plans for clinical translation are not required, although applications may have aims that illustrate translational potential.

Examples of responsive research questions include, but are not limited to:

• How do known driver mutations such as p53, KRAS, and MYC influence lipid metabolism in tumor cells in response to diet?
• What are the molecular mechanisms that moderate the differential effects of different biochemical species of dietary lipids, such as palmitate and linoleic acid, on tumor progression?
• How do diet-driven variations in the level and/or composition of fatty acids in serum or tumor interstitial fluid impact any or all of the following molecular processes in tumor and stromal cells?
  • lipid-mediated signaling
  • de novo lipogenesis
  • mitochondrial function
  • the production of reactive oxygen species
• How are alterations in diet-responsive lipid metabolism in tumors buffered or enhanced by the tumor microenvironment?
• What are the molecular mechanisms through which diet-responsive circulating factors such as adipokines and steroid hormones influence cancer cell metabolism and tumor progression?
• How does dietary composition affect lipid metabolism in tumors and the tumor microenvironment in the absence of weight gain?

Applications that examine how any of the above topics contribute to health disparities are welcome and encouraged.

To ensure appropriate expertise in nutrition, all applicants are encouraged to include a co-Investigator or use an MPI structure as appropriate to the work proposed.

Awardees will be expected to collaborate, share data and expertise, and participate in joint activities, including any NCI-organized working group(s) drawn from all funded U01 and UH2 research projects as are jointly determined to be needed by the awardees and participating NCI staff. Other NCI awardees with relevant expertise may be invited to join the working group(s) as associate members.

Recipients of awards under this NOFO will also be expected to present their results at a virtual annual meeting that will be open to the scientific community at large.

Section V. Application Review Information

1. Criteria

Only the review criteria described below will be considered in the review process. Applications submitted to the NIH in support of the NIH mission are evaluated for scientific and technical merit through the NIH peer review system.

For this particular announcement, note the following:

The priority for this FOA is to stimulate fundamental cancer research that will address knowledge gaps and current technical challenges that limit our understanding of the connection between (1) diet and nutrition and (2) the cancer-relevant catabolism and anabolism of lipids, including the roles these metabolic processes play in supporting the function of lipids as energy sources, signaling molecules, post-translational modifications, and/or components of physical structures such as membranes. Since lipids are both the building blocks and end products of other metabolic reactions, applications may involve studies of the biosynthesis or degradation of other macromolecules as they specifically relate to lipid metabolism.

Applications are not limited to those that propose modifications of dietary lipids. Any dietary manipulation that has a downstream effect on some aspect of lipid metabolism in tumors, or on some tumor cell non-autonomous factor, such as systemically circulating molecules or non-cancerous cells in the tumor microenvironment, that influences tumor growth and progression by acting on lipid metabolism, is of equal interest.

Applications do not need to show any potential for direct clinical translation. Potential for clinical translation is not a requirement for this FOA.

Reviewers will provide an overall impact score to reflect their assessment of the likelihood for the project to exert a sustained, powerful influence on the research field(s) involved, in consideration of the following scored review criteria and additional review criteria (as applicable for the project proposed). An application does not need to be strong in all categories to be judged likely to have a major scientific impact.

Reviewers will evaluate Factors 1, 2 and 3 in the determination of scientific merit, and in providing an overall impact score. In addition, Factors 1 and 2 will each receive a separate criterion score. 

As applicable for the project proposed, reviewers will consider the following additional items while determining scientific and technical merit, but will not give criterion scores for these items, and should consider them in providing an overall impact score.

As applicable for the project proposed, reviewers will consider each of the following items, but will not give scores for these items, and should not consider them in providing an overall impact score.

2. Review and Selection Process

Applications will be evaluated for scientific and technical merit by (an) appropriate Scientific Review Group(s) convened by NCI, in accordance with NIH peer review policy and procedures, using the stated review criteria. Assignment to a Scientific Review Group will be shown in the eRA Commons.

As part of the scientific peer review, all applications will receive a written critique.

Applications may undergo a selection process in which only those applications deemed to have the highest scientific and technical merit (generally the top half of applications under review) will be discussed and assigned an overall impact score.

Applications will be assigned on the basis of established PHS referral guidelines to the appropriate NIH Institute or Center. Applications will compete for available funds with all other recommended applications submitted in response to this NOFO. Following initial peer review, recommended applications will receive a second level of review by the appropriate national Advisory Council or Board. The following will be considered in making funding decisions:

• Scientific and technical merit of the proposed project as determined by scientific peer review.
• Availability of funds.
• Relevance of the proposed project to program priorities.

If the application is under consideration for funding, NIH will request "just-in-time" information from the applicant as described in the NIH Grants Policy Statement Section 2.5.1. Just-in-Time Procedures. This request is not a Notice of Award nor should it be construed to be an indicator of possible funding.

Prior to making an award, NIH reviews an applicant’s federal award history in SAM.gov to ensure sound business practices. An applicant can review and comment on any information in the Responsibility/Qualification records available in SAM.gov. NIH will consider any comments by the applicant in the Responsibility/Qualification records in SAM.gov to ascertain the applicant’s integrity, business ethics, and performance record of managing Federal awards per 2 CFR Part 200.206 “Federal awarding agency review of risk posed by applicants.” This provision will apply to all NIH grants and cooperative agreements except fellowships.

3. Anticipated Announcement and Award Dates

After the peer review of the application is completed, the PD/PI will be able to access his or her Summary Statement (written critique) via the eRA Commons. Refer to Part 1 for dates for peer review, advisory council review, and earliest start date.

Information regarding the disposition of applications is available in the NIH Grants Policy Statement Section 2.4.4 Disposition of Applications.

Section VI. Award Administration Information

1. Award Notices

Thus, criteria in research protocols that target or exclude certain populations are warranted where nondiscriminatory justifications establish that such criteria are appropriate with respect to the health or safety of the subjects, the scientific study design, or the purpose of the research. For additional guidance regarding how the provisions apply to NIH grant programs, please contact the Scientific/Research Contact that is identified in Section VII under Agency Contacts of this NOFO.

All federal statutes and regulations relevant to federal financial assistance, including those highlighted in NIH Grants Policy Statement Section 4 Public Policy Requirements, Objectives and Other Appropriation Mandates.

Recipients are responsible for ensuring that their activities comply with all applicable federal regulations.  NIH may terminate awards under certain circumstances.  See 2 CFR Part 200.340 Termination and NIH Grants Policy Statement Section 8.5.2 Remedies for Noncompliance or Enforcement Actions: Suspension, Termination, and Withholding of Support. 

The following special terms of award are in addition to, and not in lieu of, otherwise applicable U.S. Office of Management and Budget (OMB) administrative guidelines, U.S. Department of Health and Human Services (HHS) grant administration regulations at 2 CFR Part 200, and other HHS, PHS, and NIH grant administration policies.

The administrative and funding instrument used for this program will be the cooperative agreement, an "assistance" mechanism (rather than an "acquisition" mechanism), in which substantial NIH programmatic involvement with the recipients is anticipated during the performance of the activities. Under the cooperative agreement, the NIH purpose is to support and stimulate the recipients' activities by involvement in and otherwise working jointly with the recipients in a partnership role; it is not to assume direction, prime responsibility, or a dominant role in the activities. Consistent with this concept, the dominant role and prime responsibility resides with the recipients for the project as a whole, although specific tasks and activities may be shared among the recipients and NIH as defined below.

The PD(s)/PI(s) will have the primary responsibility for:

• Overseeing the scientific progress of the Research Project, analyzing and interpreting research data, reporting results to the scientific community, and disseminating approaches, methods, models, software, and tools broadly;
• Agreeing to be an active participant in group activities organized for recipients by NCI staff, including attending the virtual Annual Investigators Meeting and other relevant NCI-sponsored meetings and workshops;
• Collaborating with other NCI recipients to advance research on the connections between diet, lipid metabolism, and tumor growth and progression;
• Abiding by all directives issued by NCI program officials responsible for supervision of the awarded project, consistent with the applicable rules and regulations governing cooperative agreements;
• Reporting progress to the NCI program officials on all research and activities annually. The PD(s)/PI(s) may be expected to provide additional information, outside the scope of the standard reporting requirement, as needed and requested by program staff members on a semi-annual basis;
• Providing other information as might be requested by project scientist (e.g., on project milestones, methodology, procedures, etc.)
• Ensuring that data are deposited in a timely manner in appropriate publicly available databases and that models, software, and other tools and resources developed as part of this Research Project are made publicly available according to NIH and NCI policies;
• Ensuring that results of the Research Projects are published in a timely manner;
• Participating in the NCI-coordinated evaluation of awards made under this NOFO;
• Facilitating collaboration and validation of experimental concepts and observations on the topic of diet, lipid metabolism, and tumor growth/progression by participating in any scientific working group(s) jointly determined to be needed by the recipients and participating NCI staff; and
• Notifying NCI program staff members about research pilot projects.

Recipients will retain custody of and have primary rights to the data and software developed under these awards, subject to Government rights of access consistent with current DHHS, PHS, and NIH policies.

The NCI reserves the right to adjust funding, withhold, suspend, or terminate the support to the recipient if the investigators are unable to meet the performance requirements set forth in the required policies and procedures.

NCI program staff have substantial programmatic involvement that is above and beyond the normal stewardship role in awards. The substantially involved NCI program staff member(s), acting as project scientist(s), will coordinate in a centralized fashion various activities of the recipients. Specific responsibilities of the NCI project scientist(s) will include, but will not be limited to the following:

• Monitoring the specific technical direction of projects, including recommending approval of changes in experimental approaches;
• Assisting both individual award recipients as well as any scientific working group(s) jointly determined to be needed by the recipients and participating NCI staff in avoiding unwarranted duplications of effort;
• Facilitating collaborative research efforts between recipients;
• Serving as a resource for recipients, particularly in making them aware of other ongoing NCI activities that may be relevant to the study of diet, lipid metabolism, and tumor growth and progression;
• Assisting the recipients as a resource by facilitating their broader interactions with other NCI and NIH programs to disseminate results, tools, and models and take advantage of existing NIH/NCI resources and infrastructures;
• Evaluating the effectiveness of standards and best practices developed by recipients to link dietary and metabolic research, and promoting the adoption of these standards and best practices by the broader community, including through publications;
• Monitoring the operations of award recipients and making recommendations on overall project directions;
• Reviewing the progress of the program;
• Leading the organization of annual meetings, specialized workshops, and webinars of the consortium, including meetings of any working group(s) jointly determined to be needed by the recipients and participating NCI staff.

The substantially involved NCI staff members will not attend peer review meetings. If such participation is deemed essential, these individuals will seek NCI waivers according to the NCI procedures for management of conflict of interest. In addition, an NCI program director acting as a program official will be responsible for the normal scientific and programmatic stewardship of the award and will be named in the award notice.

Areas of Joint Responsibility include:

Since the purpose of this NOFO is to establish and/or further develop collaborative arrangements between extramural investigators, including but not limited to the identification of new research directions and models, many responsibilities are shared between recipients and NIH staff and will require close coordination. Responsibilities will be divided between recipients and NIH staff, as described above.

Dispute Resolution:

Any disagreements that may arise in scientific or programmatic matters (within the scope of the award) between recipients and NIH may be brought to Dispute Resolution. A Dispute Resolution Panel composed of three members will be convened: a designee of the Steering Committee chosen without NIH staff voting, one NIH designee, and a third designee with expertise in the relevant area who is chosen by the other two; in the case of individual disagreement, the first member may be chosen by the individual recipient. This special dispute resolution procedure does not alter the recipient's right to appeal an adverse action that is otherwise appealable in accordance with PHS regulation 42 CFR Part 50, Subpart D and HHS regulation 45 CFR Part 16.

Consistent with the 2023 NIH Policy for Data Management and Sharing, when data management and sharing is applicable to the award, recipients will be required to adhere to the Data Management and Sharing requirements as outlined in the NIH Grants Policy Statement. Upon the approval of a Data Management and Sharing Plan, it is required for recipients to implement the plan as described.

4. Reporting

When multiple years are involved, recipients will be required to submit the Research Performance Progress Report (RPPR) annually and financial statements as required in the NIH Grants Policy Statement Section 8.4.1 Reporting. To learn more about post-award monitoring and reporting, see the NIH Grants & Funding website, see Post-Award Monitoring and Reporting.

A final RPPR, invention statement, and the expenditure data portion of the Federal Financial Report are required for closeout of an award, as described in the NIH Grants Policy Statement Section 8.6 Closeout. NIH NOFOs outline intended research goals and objectives. Post award, NIH will review and measure performance based on the details and outcomes that are shared within the RPPR, as described at 2 CFR Part 200.301.
