doi: 10.7150/ijbs.125429
Figure Lengend Snippet: Effect of TRPV1 receptor silencing on cell viability and proliferation. LNCaP, PC3, and DU-145 cells were infected with either an empty vector (EV) or a shTRPV1 vector via lentivirus-mediated transduction. (A) Cell viability of prostate cancer cells. Following infection, the cells were seeded at equal densities, and MTT assays were performed at 12, 24, and 48 hours post-seeding to evaluate the impact of TRPV1 silencing on cell proliferation. Data from non-silenced and silenced cells were normalized to 1 to facilitate the comparison. The mean ± SD of three independent experiments is shown. (B) Protein expression levels of proteins involved in proliferation, cell cycle regulation and mitosis. The levels of the proteins were determined by Western blotting, and β-actin served as a loading control. The densitometric analyses of the bands represent the mean ± SD of three different experiments. (C) Relative mRNA expression levels of the stemness markers Oct4, Nanog and ABCB1A. mRNA levels were quantified via RT-qPCR, normalized to actin (housekeeping gene) and presented as mean ± SD of six independent experiments. (D) Correlation analysis between TRPV1 and the stemness markers Oct4, Nanog and ABCB1A in TRPV1-silenced cells. Top: Scatter plots showing Pearson's correlation coefficients (r) for TRPV1 vs. Oct4, TRPV1 vs. Nanog and TRPV1 vs. ABCB1A. Bottom: Heatmap displaying Pearson's correlation coefficients for TRPV1, Oct4, Nanog and ABCB1A expression. p < 0.05 (*), p < 0.01 (**), p < 0.001 (***) and p < 0.0001 (****) indicate significant differences according to two-way ANOVA and Sidak's multiple comparisons test.
Article Snippet: The human prostate cancer cell lines LNCaP (CRL-1740), PC3 (CRL-1435), and DU-145 (HTB-81) were purchased from the American Type Culture Collection (ATCC, Manassas, VA, USA).
