Supplementary Figure 2: TP53INP2 loss-of-function promotes adipose hyperplasia.

Panels a, b and c: TP53INP2 mRNA levels in human subcutaneous and visceral adipose tissue are inversely proportional to BMI. The sample size of the study 1 is n = 24 samples of scWAT (a) and n = 38 samples of vWAT (b). In the study 2, the sample size is n = 35 samples of scWAT. Statistical significance was calculated using a Spearman correlation analysis (r = -0.439 and P = 0.0051 (a); r = -0.567 and P = 0.0002 (b); r = -0.348 and P = 0.04 (c); d) Experimental design for the generation of TP53INP2 KOUbc mice: two-month-old mice expressing CreTP53INP2loxP/loxP and their non-expressing Cre-ERT2TP53INP2loxP/loxP control littermates were fed a tamoxifen diet. Experimental data were collected 2 months after starting the tamoxifen diet; Panels e to j: Control and TP53INP2 KOUbc four-month-old mice. Data represent means ± SEM. (e) TP53INP2 mRNA levels in ingWAT (n = 4 control and n = 5 KOUbc mice) and vWAT (n = 5 control and n = 7 KOUbc mice). Statistical significance was calculated using an unpaired two-tailed t-test (*P = 0.0002 and #P < 0.0001); (f) TP53INP2 protein expression in ingWAT (n = 3) and pgWAT (n = 3) depots; (g) TP53INP2 mRNA levels in other tissues (n = 3 samples for each tissue). Statistical significance was calculated using an unpaired two-tailed t-test (*P = 0.0139; #P = 0.0031; §P ≤ 0.0001 and &P = 0.0004); Panels h and i: Tissues weigh of females (h) (Brain, kidney and heart: n = 10 control and n = 15 KOUbc mice, and Gastroc, Quads and Tib: n = 5 control and n = 9 KOUbc mice) and males (i) (n = 4 control and n = 7 KOUbc mice). Data represent means ± SEM. Statistical significance was calculated using an unpaired two-tailed t-test; j) Fsp27, Perilipin, Leptin, Resistin, LPL and VEGF mRNA levels in adipose tissue. Data represent means ± SEM (n = 4 control and n = 6 KOUbc mice). Statistical significance was calculated using an unpaired two-tailed t-test (*P = 0.0113; #P = 0.0320; §P < 0.0271; &P = 0.0452; °P = 0.0465 and +P < 0.0107).
