    Figure Lengend Snippet: Rescue of RAB25-mediated HSCs activation by PI3K/AKT inhibition. HepG2.2.15 cells were co‑cultured with LX‑2 hepatic stellate cells transiently transfected with a RAB25 overexpression vector; cells were treated with either dimethyl sulfoxide (DMSO) as vehicle control or the selective PI3K inhibitor LY294002 at a concentration of 10 μM for 24 h. Then, treated HSCs were examined for A: the total and phosphorylated PI3K and AKT level using Western blot; B: cell viability using CCK-8; C: cell proliferation by colony formation assay; D: cell migration through scratch assay; E: the expression levels of α-SMA, Collagen I, MMP2, and PCNA using Western blot. N=3 (biological replicates). ** P < 0.01, vs. HepG2.2.15+HSC-RAB25+DMSO group.

    Article Snippet: Serum samples were collected from all participants after overnight fasting and stored at −80°C for subsequent serum RAB25 expression analysis by ELISA (Human RAB25 ELISA Kit, SLD4057Hu, Sunlong Biotech, Hangzhou, China).
