Involvement of SRPK1 in cisplatin resistance related to long non-coding RNA UCA1 in human ovarian cancer cells

Abstract

The therapeutic potential of cisplatin in ovarian cancer treatment is restricted by the occurrence of cellular resistance. We aimed to explore the role of SRPK1 in cisplatin resistance related to the long non-coding RNA UCA1 in ovarian cancer cell. Totally, 24 ovarian cancer tissues and 16 normal tissues were used to assess the expression of UCA1 RNA. UCA1 stable transfected SKOV3 cells were established and the ability of cell migration, invasion and cisplatin resistance was assessed. The expression of SRPK1 and apoptosis pathway proteins was then assessed to explore the mechanism. In addition, SRPK1 knockdown cell line was also established and the effects of SRPK1 on cell migration, invasion and cisplatin resistance was evaluated. Elevated expression of UCA1 RNA was identified in ovarian cancer tissues compared with normal tissues. Expression of UCA1 RNA in SKOV3 cells enhanced the cell migration, invasion and cisplatin resistance. Increased expression of SRPK1 and anti-apoptosis proteins were found in SKOV3/pcDNA-UCA1 cells. Knocking-down SRPK1 could partly rescue the effect of UCA1 expression on cell migration, invasion and cisplatin resistance in SKOV3 cells. Elevated expression of UCA1 RNA was found in ovarian cancer tissues. UCA1 can improve the cell migration, invasion and induce cisplatin resistance. SRPK1 and apoptosis pathway proteins may be involved in the effect of UCA1.
