【摘要】:目的探討生長抑素受體2(SSTR2),凋亡抑制因子Livin和存活素(Survivin)在結(jié)腸正常黏膜、結(jié)腸腺瘤、癌旁組織及結(jié)腸癌組織中的表達水平的變化規(guī)律及臨床意義。方法采用逆轉(zhuǎn)錄聚合酶鏈反應(RT-PCR)方法檢測收集到的30例結(jié)腸正常黏膜、30例結(jié)腸腺瘤、30例結(jié)腸癌旁組織、30例結(jié)腸癌組織中SSTR2、Livin和Survivin mRNA的表達情況,對其表達水平進行測定,分析不同組織表達陽性率及表達強度的差別。結(jié)果結(jié)腸癌標本中Livin和Survivin mRNA陽性表達率與結(jié)腸腺瘤比較明顯升高,差異有統(tǒng)計學意義(P0.05)。而SSTR2mRNA的陽性表達率與結(jié)腸腺瘤比較明顯降低,,差異有統(tǒng)計學意義(P0.05)。Livin和Survivin mRNA表達水平在結(jié)腸正常黏膜、結(jié)腸腺瘤、結(jié)腸瘤旁組織、結(jié)腸癌組織為逐漸增高趨勢,而SSTR2mRNA為逐漸下降趨勢。結(jié)論 SSTR2、Livin和Survivin在結(jié)腸黏膜從腺瘤到癌的轉(zhuǎn)變過程中起著重要作用。
[Abstract]:Objective to investigate the expression of somatostatin receptor 2 (SSTR2), inhibitor of apoptosis (Livin) and survivin (Survivin) (survivin (Survivin) in normal colon mucosa, colon adenoma, paracancerous tissues and colon cancer tissues. Methods reverse transcriptase polymerase chain reaction (RT-PCR) was used to detect the expression of SSTR2,Livin and Survivin mRNA in 30 cases of normal colonic mucosa, 30 cases of colonic adenoma, 30 cases of paracancerous tissue and 30 cases of colon cancer. The positive rate and intensity of expression in different tissues were analyzed. Results the positive expression rate of Livin and Survivin mRNA in colon cancer was significantly higher than that in colon adenoma (P0.05). The positive expression rate of SSTR2mRNA was significantly lower than that of colon adenoma, and the difference was statistically significant (P0.05) the expression of). Livin and Survivin mRNA in normal colonic mucosa, colonic adenoma, colon cancer tissue were gradually increased. However, SSTR2mRNA decreased gradually. Conclusion SSTR2,Livin and Survivin play an important role in the transition of colon mucosa from adenoma to carcinoma.
