Expression of long non-coding RNA SNHG3 in breast cancer and its clinical significance / 医学研究生学报

ABSTRACT

ObjectiveThere are a few reports about the expression of SNHG3 in breast cancer and its effects. This study aimed to detect the expression of SNHG3 in breast cancer and paracancerous tissues, along with its relevance to clinicopathological parameters.MethodsSeventy-four patients with breast cancer were confirmed pathologically in our hospital from Jan. 2014 to Dec. 2017. The expression of SNHG3 was examined in breast cancer and paracancerous tissues by qRT-PCR. Correlations between the expression of SNHG3 and clinicopathological parameters were analyzed.Results SNHG3 expression was significantly downregulated in breast cancer tissues compared to paracancerous tissues, and the difference was of statistical significance (P<0.000). Low expression of SNHG3 was in negative correlation to Ki-67 (rs=-0.296, P=0.013).ConclusionThe expression of SNHG3 downregulated in breast cancer tissues, and its expression level is related to Ki-67, which may serve as a potential diagnostic molecular marker.
