Article Title: Obesity alters the fitness of peritumoral adipose tissue, exacerbating tumor invasiveness in renal cancer through the induction of ADAM12 and CYP1B1

doi: 10.1002/1878-0261.13782

Figure Lengend Snippet: Adipose peritumoral tissue affects the expression of inflammatory genes by renal cell carcinoma (RCC) cells. (A) Relative mRNA expression of the different tumor suppressor genes in the healthy and tumor kidney tissues of RCC patients ( n = 10), including VHL , PBRM1 , SETD2 , and BAP1 , was measured by real‐time PCR. Cyclophilin‐A was used as an internal control. Data are shown as mean ± SD from at least 3 separate experiments. P ‐values were determined by Student's t ‐test. (B) Schematic figure illustrating the protocol for differentiation of adipocytes from peritumoral adipose tissue (AT) of lean, overweight, and obese RCC patients. (C) Relative mRNA expression of the leptin and adiponectin of the differentiated adipocytes among the lean, overweight, and obese groups ( n = 6). Data are shown as mean ± SD from at least 3 separate experiments. P ‐values were determined by one‐way ANOVA. (D) Schematic figure of the conditioned medium (CM) experiment, showing RCC cells treated with conditioned media (CMs) of lean, overweight, and obese differentiated adipocytes. (E) Relative mRNA expression of the IL6 , CXCR4 , SDF1 , and BAFFR of the A498 cells treated with CMs collected from differentiated adipocytes derived from the lean, overweight, and obese groups ( n = 6). Data are shown as mean ± SD from at least 3 separate experiments. P ‐values were determined by one‐way ANOVA. * P < 0.05, ** P < 0.01, *** P < 0.001, and **** P < 0.0001.
