3/24/23: Ngozi is a Ford Fellow!
Congratulations to Ngozi for her selection as a Ford Fellow. This is an extremely prestigious award given to fewer than 5% of applicants – worse odds than NIH grants! – and Ngozi’s selection represents her stellar academic prowess, promise as a scientist, and truly off-the-charts community engagement. We are so proud of Ngozi!
3/13/23: Welcome Yanitza
We are thrilled to welcome Yanitza Rodriguez as the newest member of the Perry lab.

12/16/22: The lab receives an R21 on exercise and lung cancer
We are humbled to announce that we have received R21 funding from the NCI to study whether and by what mechanism aerobic exercise may improve the response to immunotherapy for lung cancer in mice. The third submission was the charm! With this project, we hope to generate mechanistic evidence in support of clinical trials to develop lifestyle modifications (i.e., exercise) for patients with or at risk for lung cancer.
12/2/22: Xinyi’s paper published in Cancer & Metabolism
Congratulations to Xinyi, whose paper titled “Isotope tracing reveals distinct substrate preference in murine melanoma subtypes with differing anti-tumor immunity” was published in Cancer & Metabolism today! In this work, we utilized in vitro and in vivo murine melanoma models across a spectrum of immunogenicity to reveal a greater metabolic dependence in cell lines with higher immunogenicity. These data corroborate – but much additional work will be required to confirm – the hypothesis that nutrient competition in the tumor microenvironment may be one of the mechanisms by which the immune system suppresses tumor progression.

It’s a delight to welcome Susana Nakandakari to the lab! Susana is a PhD student in Brazil who will be joining the Perry and Wang labs for the next year. She is interested in metabolism and sepsis, and will join our mouse infusion team. Glad to have you onboard, Susana!
8/4/22: Briana’s summer in our lab has flown by!
We are sad to say goodbye (for now) to Briana, but congratulate her on the wonderful job she did this summer! We appreciate the great job she did working on fatty acid oxidation in melanoma cells, as well as helping Xinyi with behavioral tests in mice. It was a pleasure to have you, Briana!
7/18/22: The Perry lab welcomes visitors from the Yale Pathways to Science program
Briana, Xinyi, and Rachel enjoyed welcoming local high school students to the Perry lab today for a session focused on exercise physiology! Students had a chance to try three tests with the mice (hands-off, following all the rules): swim test, grip strength test, and maximal speed test. We developed hypotheses as to who would perform better and worse, and tested them. Most were correct (unlike the majority of scientific experiments). By the end, students were cheering on the mice! It was a joy to have the students in the lab, and we hope to do this again.
7/17/22: Stephan’s commentary is published in Diabetes Practice Update
Stephan’s commentary on SGLT2 inhibitors for patients with type 1 diabetes came out today in Diabetes Practice Update. The commentary can be found here. Nice job!

Congratulations to Brooks and the rest of our team on the publication of their new paper in npj Precision Oncology. In this work, we utilize a multi-omics approach to identify new features of the relationships between body weight, tumor genomics, and tumor metabolism. This work was completed thanks to Brooks’ ability to quickly pivot to in silico work during an era of supply chain issues and limited funding in the lab. Well done!
12/21/21: News of a JDRF award
We have received the good news of an Innovative Award from the Juvenile Diabetes Research Foundation, supporting our work aiming to identify a new hypoglycemia counterregulatory factor! This work will be conducted in close collaboration with Dr. Andrew Wang, co-PI of the award.
12/3/21: First Perry lab R01 funded – and upgraded!
Rachel is humbled and grateful to announce that our first R01, titled “Defining the Role of Renal Gluconeogenesis in Renal Cell Carcinoma,” has been selected for funding by the NIH (NCI)! The publicly available abstract reads as follows:
Renal cell carcinoma is the most common primary kidney cancer, representing 90-95% of primary renal neoplasms. Obesity and diabetes are associated with an increased risk of renal cell carcinoma, but the mechanisms by which systemic metabolic changes promote tumor progression are unknown. Although its reputation as a glucose-producing organ has been dwarfed by that of the liver over the years, the kidney possesses the same complement of gluconeogenic enzymes as the liver – with a higher concentration of gluconeogenic proteins per gram of tissue in the kidney, suggesting that its gluconeogenic capacity may even exceed the liver’s. Glucose is well-known to be a crucial substrate for tumor growth; given the gluconeogenic activity of the kidney, it is likely that increased renal gluconeogenesis may fuel tumor growth. However, this phenomenon, and its mechanistic explanation, remains to be explored. We have recently found that fibroblast growth factor-21 (FGF-21) promotes renal gluconeogenesis during starvation by activating intrarenal lipolysis through a b2-adrenergic pathway, thereby activating pyruvate carboxylase flux in healthy rodents. Therefore, this proposal will test the Overarching Hypothesis that in renal cell carcinoma, increased FGF-21 acts through a similar mechanism to promote intrarenal lipolysis, pyruvate carboxylase activity, and as a result, gluconeogenesis, and that this increased renal glucose supply fuels tumor growth. We will also examine the utility of an FGF-21 neutralizing antibody against mice genetically prone to renal cell carcinoma, which we anticipate will reduce renal gluconeogenesis and renal cell carcinoma progression. If the hypotheses are confirmed, these data would identify FGF-21 – which is already being targeted in advanced clinical trials for metabolism- and diabetes-related indications – as a potential therapeutic target in renal cell carcinoma.
This project will be conducted collaboratively with Drs. Adewobale Adeniran and Andrew Wang.
It was extra exciting to learn that the grant is eligible for conversion from a 5-year R01 to a 7-year R37 MERIT (Method to Extent Research In Time) award! We are committed to doing the most we can with this award to make discoveries in mice that may predict how metabolism can be targeted to improve outcomes for patients with renal cell carcinoma.
Important note: Although this is our first funded R01, it is *far* from the first NIH grant Rachel has submitted. For anyone wanting to commiserate about the ups and downs of the grant writing process, feel free to contact her!
11/5/21: Brooks receives a travel award to the Keystone tumor immunometabolism meeting
