Objective:
To investigate the expression of SCD1 in TFE3-rRCC and its effect on the proliferation and migration of TFE3-rRCC cells.
Methods:
GEPIA database was used to analyze the expression level of SCD1 in different tumors and its effect on the prognosis of patients. The expression levels of SCD1 in TFE3-rRCC patients and cell lines UOK109 and UOK120 were detected by QPCR and Western blot. Liposomal shRNA was used to knock down SCD1 expression in cell lines. The changes of cell proliferation and migration ability before and after SCD1 knockdown were detected by CCK-8 and Transwell experiments.
Results:
SCD1 expression levels were higher in all three common renal cancers, and patients with high SCD1 expression had shorter survival and worse prognosis (Logrank P<0.001). The mRNA and protein levels of SCD1 were also significantly increased in renal cancer tissues of patients with high expression of TFE3 and in TFE3-rRCC cell lines UOK109 and UOK120. After SCD1 knockdown, the proliferation and migration ability of UOK109 and UOK120 cells decreased significantly.
Conclusion:
SCD1 is highly expressed in TFE3-rRCC and can promote the proliferation and migration of TFE3-rRCC cell lines, which may be a key molecule in promoting the development of TFE3-rRCC.
