Small nucleolar RNA host gene 3 functions as a novel biomarker in liver cancer and other tumour progression

Cancer has become the most life-threatening disease in the world.Mutations in and aberrant expression of genes encoding proteins and mutations in noncoding RNAs,especially long noncoding RNAs(lncRNAs),have significant effects in human cancers.LncRNAs have no protein-coding ability but function extensively in numerous physiological and pathological processes.Small nucleolar RNA host gene 3(SNHG3)is a novel lncRNA and has been reported to be differentially expressed in various tumors,such as liver cancer,gastric cancer,and glioma.However,the interaction mechanisms for the regulation between SNHG3 and tumor progression are poorly understood.In this review,we summarize the results of SNHG3 studies in humans,animal models,and cells to underline the expression and role of SNHG3 in cancer.SNHG3 expression is upregulated in most tumors and is detrimental to patient prognosis.SNHG3 expression in lung adenocarcinoma remains controversial.Concurrently,SNHG3 affects oncogenes and tumor suppressor genes through various mechanisms,including competing endogenous RNA effects.A deeper understanding of the contribution of SNHG3 in clinical applications and tumor development may provide a new target for cancer diagnosis and treatment.

SNHG3基因在子宫腺肌病中的表达及对于治疗方向的初步研究

目的:探究小核仁RNA宿主基因3(SNHG3)在子宫腺肌病中的表达及意义。方法:收集32例子宫腺肌病患者的异位子宫内膜和45例对照组的子宫内膜组织,进行qRT-PCR实验,检测SNHG3基因的mRNA表达水平;采用Western blot技术检测SNHG3基因的蛋白表达水平。同时收集这些病人的诊疗数据,分析两组患者临床性状的差异性。结果:SNHG3基因在子宫腺肌病异位内膜组织中mRNA表达比对照组增高,其表达差异具有统计学意义(t=3.190,P=0.002)。腺肌病组的SNHG3基因的蛋白表达水平较对照组上调,差异有统计学意义(t=15.169,P=0.001)。两组临床资料结果显示是否合并子宫肌瘤在两组间差异具有统计学意义(P=0.002)。结论:SNHG3基因与子宫腺肌病的发生具有一定的相关性,为治疗方向提供新思路。
