To clarify the function of SUN5 in CRC, we established stable SUN5 overexpression cells (LoVo and DLD-1 transfected with pLVX-IRES-Puro-SUN5-Flag lentivirus) and knockdown cells (LoVo and DLD-1 transfected with PLV3ltr-ZsGreen-Puro-U6-shSUN5 lentivirus). This evidence concerns the gene SUN5 and colorectal carcinoma.
