Estrogens determine the efficacy of cancer immunotherapy in obese males with melanoma

Project description:Although obesity is a major risk factor for cancer, it may also improve the response to cancer therapy. Here we investigated the impact of obesity on the efficacy of immune checkpoint inhibitors. In male mice, obesity promoted tumor growth but enhanced the response to ICI. In contrast, in non-obese mice, no difference in tumor growth was observed between mice receiving anti-PD-1 or isotype control antibodies.Using transcriptome analysis of bulk tumors, we showed a distinct effect of anti-PD-1 treatment in obese versus non-obese mice. We further compared the gene expression profile of tumors from obese and non-obese mice in absence of treatment to investigate the mechanisms behind the increased efficacy of anti-PD-1 in obese mice. Our findings suggest that estrogens could be an obesity-derived factor modulating the sensitivity to PD-1 blockade in male mice.

Transcription profiling of cultured human preadipocytes/stromal vascular cells from obese and non-obese Pima Indians

Project description:Microarray analysis comparing gene expression profiles of primary cultured preadipocytes from non-diabetic lean vs non-diabetic obese Pima Indian subjects (a subset of the subjects from the adipocyte genechip project, GSE2508). Primary cultured abdominal subcutaneous preadipocytes from 14 lean (7 Males / 7 Females) and 14 obese (7M/7F) subjects were hybridized individually to Affymetrix oligonucleotide arrays HG-U133A and B.

Expression data from Lean and Obese Rat Mammary Glands, with and without treatment with bazedoxifene + conjugated estrogens (BZA/CE)

Project description:Many risk-eligible women refuse tamoxifen for primary prevention of breast cancer due to concerns about common side effects such as vasomotor symptoms. Tamoxifen may also induce or worsen insulin resistance and hypertriglyceridemia, especially in women with obesity. Bazedoxifene/conjugated estrogens (BZA/CE) reduces vasomotor symptoms and is currently undergoing evaluation for breast cancer risk reduction. However, the impact of BZA/CE on insulin resistance and metabolic health, particularly in those with excess adiposity, is understudied. Here, we examined the effects of obesity on response to BZA/CE in a rat model of breast cancer risk using older ovary-intact rats. Female Wistar rats received carcinogen to increase mammary cancer risk and were fed a high-fat diet to promote obesity. Lean and obese rats were selected based on adiposity, then randomized to BZA/CE or vehicle for 8 weeks. BZA/CE reduced adiposity, enriched small (insulin-sensitive) mammary adipocytes, increased the abundance of beneficial metabolic gut microbes (Faecalbaculum rodentium and Odoribacter laneus), and reversed obesity-associated changes in lipids and adipokines. BZA/CE also reversed obesity-induced mammary enrichment of cell proliferation pathways, consistent with risk-reducing effects. Together, these data support the use of BZA/CE to improve metabolic health and reduce breast cancer risk in individuals with obesity. RNA from mammary glands was analyzed by gene expression microarray.

Uterine Transcriptional Profile Following Treatment with Estradiol or Synthetic Estrogens Diethylstilbestrol and Propyl Pyrazole Triol

Project description:Transcriptional responses in ovariectomized mouse uterine tissue to estradiol (E2) and diethylstilbestrol (DES), known long-acting estrogens, and propyl pyrazole triol (PPT), an ER-alpha selective estrogen, were profiled. Profiles were used together with those from other estrogens to derive a biomarker panel.
