Fig. 1. SIK2 significantly increased lipid contents in ovarian cancer (OC) cells.

Fig. 1

a, b Quantitative real-time PCR (a) and Western blot (b) analyses of SIK2 expression in ovarian cancer A2780 and SKOV3 cells with treatment as indicated. siSIK2–1 and siSIK2–2, siRNAs against SIK2; siCtrl, control siRNA; SIK2, expression vector encoding SIK2; EV, empty vector. cf Cellular content of free fatty acid (c), triglyceride (d), phospholipids (e) and cholesterol (f) were detected in A2780 and SKOV3 cells with treatment as indicated. g The content of neutral lipids were detected by BODIPY 493/503 dye and counterstained with DAPI in A2780 and SKOV3 cells with treatment as indicated. Scale bars, 50 μm. Average numbers of LDs per cell (upper panel), percentage of cellular area occupied by LDs (lower panel). Data are shown as mean ± S.E.M from three independent experiments. *p < 0.05; **p < 0.01.
