Abstract:
Objective To explore the expression of urothelial carcinoma-associated 1 ( UCA1 ) in pancreatic cancer cell lines and its influence on the invasion and metastasis of the pancreatic cancer cells .Methods The expression of UCA1 in pancreatic cancer tissues and paired adjacent normal tissues ( 11 cases ) and 5 pancreatic cancer cell lines was analyzed by real-time PCR.The level of UCA1 in BxPC-3 was knocked down by small interfering RNA . The ability of invasion and migration in vitro of transfected BxPC-3 was detected by Transwell invasion assay and wound healing assay .The protein levels of MMP-2 and MMP-9 were measured by Western blot experiment .Results The expression level of UCA1 in pancreatic cancer tissues was higher than that in paired adjacent normal tissues , and UCA1 differentially expressed in 5 pancreatic cancer cell lines .Down-regulation of UCA1 by siRNA suppressed the expression of MMP-2 and MMP-9 in BxPC3, and dramatically impaired the ability of invasion and migration of BxPC-3.Conclusions UCA1 is over-expressed in pancreatic cancer , and down-regulation of UCA1 attenuates the capacity of invasion and metastasis in vitro of BxPC-3 by decreasing MMP-2 and MMP-9.
