Abstract: Beta- ersity analysis stratified by sex based on Bray-Curtis dissimilarity represents microbiome s les with metastatic melanoma in terms of the two top principal components (explaining around 17% of variance) obtained from the principal coordinate analysis. Red dots are from overweight/obese (OW/OB) BMI patients, and blue dots are from normal (NL) BMI patients. Shading inside the dots indicates the female gender. This is a subgroup analysis of Figure 5B.

Abstract: AbstractPurpose: Overweight/obese (OW/OB) patients with metastatic melanoma unexpectedly have improved outcomes with immune checkpoint inhibitors (ICI) and BRAF-targeted therapies. The mechanism(s) underlying this association remain unclear, thus we assessed the integrated molecular, metabolic, and immune profile of tumors, as well as gut microbiome features, for associations with patient body mass index (BMI). Experimental Design: Associations between BMI [normal (NL 25) or OW/OB (BMI ≥ 25)] and tumor or microbiome characteristics were examined in specimens from 782 patients with metastatic melanoma across 7 cohorts. DNA associations were evaluated in The Cancer Genome Atlas cohort. RNA sequencing from 4 cohorts ( i n /i = 357) was batch corrected and gene set enrichment analysis (GSEA) by BMI category was performed. Metabolic profiling was conducted in a subset of patients ( i x /i = 36) by LC/MS, and in flow-sorted melanoma tumor cells ( i x /i = 37) and patient-derived melanoma cell lines ( i x /i = 17) using the Seahorse XF assay. Gut microbiome features were examined in an independent cohort ( i n /i = 371). Results: DNA mutations and copy number variations were not associated with BMI. GSEA demonstrated that tumors from OW/OB patients were metabolically quiescent, with downregulation of oxidative phosphorylation and multiple other metabolic pathways. Direct metabolite analysis and functional metabolic profiling confirmed decreased central carbon metabolism in OW/OB metastatic melanoma tumors and patient-derived cell lines. The overall structure, ersity, and taxonomy of the fecal microbiome did not differ by BMI. Conclusions: These findings suggest that the host metabolic phenotype influences melanoma metabolism and provide insight into the improved outcomes observed in OW/OB patients with metastatic melanoma treated with ICIs and targeted therapies. i a href="lincancerres/article/doi/10.1158/1078-0432.CCR-22-3028" target="_blank" See related commentary by Smalley, p. 5 /a /i /

The mechanism(s) underlying this association remain unclear, thus we assessed the integrated molecular, metabolic, and immune profile of tumors, as well as gut microbiome features, for associations with patient body mass index (BMI). Associations between BMI [normal (NL & 25) or OW/OB (BMI ≥ 25)] and tumor or microbiome characteristics were examined in specimens from 782 patients with metastatic melanoma across 7 cohorts. DNA associations were evaluated in The Cancer Genome Atlas cohort. RNA sequencing from 4 cohorts (n = 357) was batch corrected and gene set enrichment analysis (GSEA) by BMI category was performed.
