Figure 1: Effect of oral intake of Plaquenil on GDF15 and ghrelin plasma levels, and hunger scores in healthy volunteers. A) Time-dependent changes in plasma GDF15 levels after oral ingestion of Plaquenil or placebo in healthy volunteers (n ¼ 10; *P < 0.05: versus baseline [10 min], ##P < 0.01: versus the placebo condition; ANCOVA mixed model). Dashed line: trendline in the fasted state; dotted line: extrapolation from trendline in the fasted state. B and C) Oral intake of Plaquenil, but not placebo, resulted in a negative correlation between GDF15 plasma levels and hungers scores measured between 0 and 90 min after administration. (n ¼ 10; Pearson correlation coefﬁcient within individuals was transformed into Fisher z to calculate the average coefﬁcient [r] and P values). D and E) Oral intake of Plaquenil, but not placebo, resulted in a negative correlation between GDF15 plasma levels and ghrelin plasma levels measured between 0 and 90 min after administration.

The effects of ID8 implantation on muscle mass, fat mass, spleen mass, GDF15 and gene expression of inflammation and atrogenes. Analysis of muscle mass at all time points in hindlimb muscles was completed (A, n = 22–24; soleus (SOL), extensor digitorum longus (EDL), plantaris (PLA), tibialis anterior (TA), gastrocnemius (GA) and quadriceps (QUAD)). Subcutaneous adipose mass in the inguinal fat depot (B, n = 9–12), serum GDF15 (C, n = 8–11) and spleen mass (D, n = 21–22) were also analyzed. mRNA content of inflammatory and atrophy markers interleukin-6 (IL-6), tumour necrosis factor – alpha (TNF-α), atrogin and muscle RING-finger protein-1 (MURF-1) were measured using quantitative PCR in the TA and diaphragm of all groups (E-H, n = 6–8). Results represent mean ± SD. Lettering denotes statistical significance when different from each other ( p < 0.05). C57BL/6J female mice ∼75 days post PBS injection as controls (CTRL); C57BL/6J female mice ∼45 days post ovarian cancer injection (45 Days); C57BL/6J female mice ∼75 days post ovarian cancer injection (75 Days); C57BL/6J female mice ∼90 days post ovarian cancer injection (90 Days). All data was analyzed using a one-way ANOVA or Kruskal–Wallis test when data did not fit normality. All ANOVAs were followed by a two-stage step-up method of Benjamini, Krieger and Yukutieli multiple comparisons test.
