Figure Lengend Snippet: Knockdown or inhibition of PYCR1 suppresses proliferation, migration, and tumor growth of BLCA cells in vitro and in vivo. ( A ) Western blot showing PYCR1 expression levels in BLCA cell lines and normal urothelial cell line SV-HUC-1. ( B ) Validation of PYCR1 knockdown efficiency in T24 and J82 cells using three different shRNAs. ( C ) CCK-8 assay showing reduced proliferation of T24 and J82 cells upon PYCR1 knockdown. ( D ) Colony formation assay indicating a significant decrease in clonogenic ability after PYCR1 knockdown. ( E ) Transwell migration assay demonstrating impaired migration in PYCR1 knockdown cells, scale bar = 200 μm. ( F ) Flow cytometry analysis of cell cycle distribution in J82 and T24 cells after PYCR1 knockdown. The G2 phase showed significant accumulation with P = 0.0036 for J82 cells and P = 0.0055 for T24 cells. ( G ) Flow cytometry analysis of apoptosis in T24 and J82 cells following PYCR1 knockdown. ( H ) Schematic diagram of xenograft mouse models used to evaluate the effects of PYCR1 inhibition in vivo ( n = 6 mice per group). ( I ) Tumor volume comparison and IHC staining (H&E, PYCR1, Ki-67) of xenografts from T24 cells treated with PYCR1 inhibitor versus DMSO control. ( J ) Tumor volume comparison and IHC staining of xenografts from T24-NC and T24-shPYCR1 cells. Data are presented as mean ± SD from three independent experiments. ns indicates P > 0.05, * P < 0.05, ** P < 0.01, *** P < 0.001, **** P < 0.0001
Article Snippet: Human BLCA cell lines (T24, J82, UMUC3, SW780) and a normal urothelial cell line (SV-HUC-1) were obtained from American Type Culture Collection (ATCC).
