SCHLAP1 and prostate adenocarcinoma: We chose the 22Rv1 cell line, a human prostate carcinoma epithelial cell line with low endogenous SChLAP1 expression, making it suitable for overexpression, and LNCaP, an androgen-sensitive prostate adenocarcinoma cell line, which naturally exhibits high SChLAP1 expression (Figure 6A).
