Leelamine (LLM) treatment decreased number of neutral lipid droplets in prostate cancer cells. A, Representative confocal microscopy images for BODIPY staining depicting neutral lipid droplets in 22Rv1 cells after 24-hour treatment with ethanol (control) or 2.5 and 5 µmol/L of LLM or Etomoxir (Etx; positive control). B, Quantitation of the number of neutral lipid droplets/cell in control and LLM-treated 22Rv1, LNCaP, PC-3, and RWPE-1 cells (24-hour treatment). Results shown are mean ± SD (n=3). Significantly different (P<0.05) *compared with ethanol-treated control, and #between LLM and Etx group by one-way ANOVA followed by Bonferroni’s test. C, Oil red O staining in 22Rv1, LNCaP, and PC-3 cells after 24 hours of treatment with ethanol (control) or the indicated doses of LLM. D, Quantitation of Oil Red O colour intensity through measurement of absorbance at 492 nm. Results are shown as mean ± SD (n=3). *Significantly different (P<0.05) compared with corresponding ethanol-treated control cells by one-way ANOVA followed by Dunnett’s test. Consistent results were observed in independent replicate experiments.
