Objective:
We aim to investigate the expression of long non-coding RNA SNHG6 and analyze its clinicopathological significance in renal cell carcinoma (RCC).
Patients And Methods:
A total of 81 cases of RCC tissues were collected and enrolled. Total RNA was extracted using the TRIzol method followed by qRT-PCR detection of the mRNA level of SNHG6. The x2-test was used to analyze the correlation between SNHG6 expression and clinicopathological variables, including age, gender, TNM stage, Fuhrman grade, tumor size, and overall prognosis. Kaplan-Meier survival curve was plotted to analyze the association between SNHG6 expression and overall survival. Univariate and multivariate analysis were carried out with the Cox proportional hazard analysis.
Results:
SNHG6 was shown to be markedly upregulated in RCC tissues as compared with normal controls. Elevated SNHG6 was found to significantly correlate with clinical stage, lymph node metastasis, Fuhrman grade, and tumor size (p<0.05). Kaplan-Meier survival analysis exhibited that elevated SNHG6 was remarkably associated with poor overall survival (p<0.001). Moreover, multivariate analysis revealed that SNHG6 expression was an independent prognostic factor in RCC.
Conclusions:
We showed that up-regulated SNHG6 was significantly associated with tumor progression and was an independent prognostic factor in RCC, suggesting that SNHG6 can work as a promising prognostic predictor in RCC.
