Figure Lengend Snippet: Effect of simvastatin on DNA repair gene expression in prostate cancer and prostate stromal cells (PrSC). PC-3, 22Rv1, LNCaP-LA, LNCaP, and PrSC cells were incubated with the medium containing 10% FBS for 24 h, and the medium was switched to the indicated concentration of simvastatin in the medium containing 10% FBS. After 48 h, the total RNA ( A , C ) and total protein ( B , D ) were collected. ( A ) Comparison of mRNA expression levels of each gene in each cell without simvastatin. mRNA expression of BRCA1, BRCA2, RAD51, FANCD2, FANCG, FANCA, BARD1, RFC3, RFC4, and RFC5 was evaluated by performing real-time polymerase chain reaction tests, and the relative quantitative volume (RQV) was calculated by comparing the expression of β-actin. Values are expressed as mean ± standard deviation (SD) ( n = 3). * P < 0.05 vs. the other cells. ( B ) Comparison of protein levels of BRCA1 and RAD51 in each cell without simvastatin. The protein expression of BRCA1 and RAD51 was evaluated by western blotting. A representative experiment is shown, which was repeated three times with similar results. ( C ) Comparison of mRNA expression levels of each gene in each cell after treatment of simvastatin. mRNA expression of BRCA1, BRCA2, RAD51, FANCD2, FANCG, FANCA, BARD1, RFC3, RFC4, and RFC5 was evaluated by performing real-time polymerase chain reaction tests, and the relative quantitative volume (RQV) was calculated by comparing the expression of β-actin. Values are expressed as mean ± standard deviation (SD) ( n = 3). * P < 0.05 vs. 0 µM of each cell. ( D ) Comparison of BRCA1 protein levels in each cell after treatment of simvastatin. The protein expression of BRCA1 was evaluated by western blotting. A representative experiment is shown, which was repeated three times with similar results

Figure Lengend Snippet: Effect of combination therapy with simvastatin and olaparib on androgen-independent prostate cancer cells. The cells were then incubated in a medium. After 48 h, the cells were cultured in a medium with or without simvastatin (PC-3, 2 µM; other cells, 5 µM) and olaparib (10 µM). After 72 h for PC-3, LNCaP, and PrSC and 120 h for LNCaP-LA and 22Rv1 cells, the number of viable cells was evaluated using MTS assay ( A ) and cell counts ( B ). Values are expressed as mean ± standard deviation (SD) (A; n = 5, B; n = 4). * p < 0.05. Sim; simvastatin, Ola; olaparib

Figure Lengend Snippet: Effect of combination therapy with simvastatin and olaparib on tumor growth and BRCA1 expression in vivo in a 22Rv1 xenograft model. Graphic view of mean tumor volumes in 22Rv1 xenografts. Mice were injected with 22Rv1 cells (3 × 10 6 per site) and subsequently orally treated with simvastatin (100 mg/kg once daily) with or without olaparib (50 mg/kg once daily). Line graphs, mean ( n = 5); bars, standard deviation (SD); * p < 0.05 vs. the other group. BRCA1 mRNA expression in xenograft tissue was analyzed via quantitative real-time PCR (B). Values are expressed as mean ± SD ( n = 5). Sim; simvastatin, Ola; olaparib
