通過miRNA基因表達譜的基因共表達網(wǎng)絡構建對星形細胞瘤的基因靶標進行預測
發(fā)布時間：2021-12-30 15:15
星形細胞瘤為浸潤性生長腫瘤,生長緩慢,多為隱形癥狀,難以早期發(fā)現(xiàn)。多數(shù)腫瘤切除后有復發(fā)可能,且復發(fā)后腫瘤可演變成間變性星形細胞瘤或多形性膠質母細胞瘤。因此尋找其生物標志物早期診斷,并研究新的治療方法就十分重要。方法:通過選用GEO數(shù)據(jù)庫的星形細胞瘤miRNA表達譜數(shù)據(jù),進行差異分析以及靶基因預測,通過2者共表達網(wǎng)絡的構建對篩選出的miRNA的研究價值進行探討。結果:得出hsa-miR-29b-2-5p;hsa-miR-339-5p與hsa-miR-362-3p3個較為關鍵的miRNA及與3者關系密切的8個mRNA。結論:通過對8個mRNA在癌癥中的作用的討論,肯定了這3個關鍵miRNA作為潛在靶點的研究價值。
