CSGALNACT2 and ovarian cancer: To further determine the role of CSGALNACT2, we used two different shRNA constructs targeting the CSGALNACT2 transcript to knockdown CSGALNACT2 expression in two HGSOC cell lines, HEY and OVCAR8, according to the mRNA and protein expression of CSGALNACT2 in normal ovarian epithelial cell line (IOSE) and ovarian cancer cell lines (Supplementary Fig. 3A).
