[Abstract] Objective To explore the role of stathmin on the C13K cell proliferation and chemosensitivity of cisplatin in ovarian cancer. Methods The stathmin expression in cisplatin-sensitive OV2008 and resistant C13K cells was detected by western blot. Effective stathmin siRNA was transfected into ovarian cancer C13K cells(Stathmin-siRNA group). Non-transfected cells were used as blank control and negative siRNA as negative control. Western blot was used to verify the siRNA interference result. MTT was used to measure the cell proliferation and the change of chemosensitivity to cisplatin. Flow cytometry was used to detect the change of cisplatin-induced cell cycle arrest. Results Stathmin expression in C13K cells was higher than that in OV2008 cells. Compared to blank control group and negative control group, Stathmin protein was significantly reduced and the proliferation was significantly inhibited in stathmin-siRNA group, and the IC50 of cisplatin in stathmin-siRNA group [(15.41±1.08) μg/mL] was significantly lower. The cell cycle in G2/M phase induced by cisplatin in stathmin-siRNA group [(27.48±0.76)%] was significantly higher than those in control group. Conclusion Interfering with stathmin can effectively inhibit the proliferation of C13K cell and effectively increase cisplatin chemosensitivity, and provide new prospects for ovarian cancer treatment.

3 评论

化疗耐药是一个多要素、多环节彼此作用、彼此影响的杂乱进程。既往研讨发现卵巢癌耐药的发作开展受多个基因的重要调控,例如野生型P53的骤变[9],BRAC1二次骤变[10],凋亡蛋白按捺分子XIAP[11]等在铂类耐药的发作开展中都发挥了重要作用。Kigawa等研讨发现野生型P53缺失能增强肿瘤对顺铂的耐受,相反,wtP53基因的重建增强了化疗灵敏性[12]。P53的骤变使肿瘤细胞丧失了G1/S检测点的调控,DNA损害修正显着削减,终究增强了顺铂化疗灵敏性[13]。因而寻觅新的基因医治靶点并进行靶向干涉,能有用反转化疗药物的耐受,为卵巢癌的诊治和延伸患者生命供给有利的协助。

Stathmin,是细胞内与细胞周期调控相关的一种重要微管调理蛋白,首要经过磷酸化和去磷酸化进程的彼此切换调理微管体系动力平衡来参加多种肿瘤的发作开展、侵袭搬运及取得性多药耐药等生物学进程,但是它的详细作用机制还未研讨清楚。Wang F等[4]发现Stathmin在食管癌中高表达,与肿瘤分解程度,肿瘤滋润深度,淋巴结搬运和TNM分期密切相关。Xu JP等[14]经过二维电泳技能发现Stathmin在阿霉素化疗耐受的白血病细胞中表达量更高,提出Stathmin 可能与白血病的耐药密切相关[14]。Werner HM等[15]研讨发现Stathmin搅扰后能显着增强子宫内膜癌对紫杉酚的灵敏性,一起Stathmin的高表达的患者承受紫杉酚化疗后其生计率更低[15]。本研讨发现Stathmin在顺铂耐药型卵巢癌细胞中的表达高于化疗灵敏细胞株,这与Balachandran R等[16]的研讨成果相一致[16],提示Stathmin可能参加了这两种细胞不同的表型差异,在卵巢癌的顺铂耐药中可能起重要作用。

RNA搅扰(RNAi)是运用同源性的双链RNA诱导特异性序列的基因靶向缄默沉静,能快速有用按捺基因的表达及其活性。siRNA是一种具有21~23个碱基的双链RNA小分子搅扰片段,能特异性辨认靶基因的序列,已广泛用于根底试验研讨和部分临床药物的研制进程[17-19]。咱们运用RNA搅扰下调卵巢癌C13K细胞中Stathmin的表达,进而进行相关体外试验研讨。本研讨调查到缄默沉静卵巢癌细胞Stathmin的表达后,细胞的体外增殖才能显着按捺,标明Stathmin参加了调理卵巢癌细胞的增殖及分解,促进肿瘤细胞的成长进程。Stathmin的以上作用可能受PCNA、P53、FOXM1等增殖相关通路的重要调控作用。咱们发现按捺Stathmin的表达能显着下降C13K细胞化疗药物顺铂的IC50值,增强其化疗的灵敏性,提示Stathmin的搅扰片段同化疗可联合运用,进步卵巢癌的医治作用。一起,咱们也发现较低剂量的顺铂能使卵巢癌细胞阻滞在S期,这样的作用一方面可以使DNA的组成显着受阻,另一方面使癌细胞有足够的时刻发动DNA损害修正机制,更简单诱导取得性耐药的发作。Shin SY等[20]研讨发现跨过S期添加G2/M期阻滞能有用添加肿瘤细胞对顺铂的灵敏性。本研讨证明Stathmin的siRNA转染能显着下降顺铂导致的S期阻滞,添加G2/M期细胞份额。由此估测,Stathmin可能经过周期调理分子彼此作用,影响细胞周期检测点功用或DNA损害修正机制,然后影响铂类耐药。当然其详细作用机制还需要进一步研讨。因而,Stathmin不只影响直接作用于微管的化疗药物如紫杉醇等的耐药性,并且对卵巢癌的顺铂耐药也有必定影响。当然,肿瘤的发作开展受多个基因联合调控,独自研讨某一基因或分子关于完全治好肿瘤远远不够,全面研讨并制作微观的基因调控网络图至关重要。

综上所述,搅扰Stathmin的表达可显着按捺卵巢癌细胞的增殖,一起经过促进细胞周期阻滞在G2/M期来增强C13K细胞对顺铂的药物灵敏性,提示Stathmin基因可能是医治卵巢癌的有用靶点。
