摘要:
目的 探讨谷胱甘肽转移酶-π(GST-π)在卵巢癌多药耐药中的作用。方法 选取2013年1月至2015年12月洛阳市中心医院卵巢癌组织56例,体外培养肿瘤细胞,采用噻唑兰(MTT)法进行体外药物敏感性试验,酶联免疫吸附试验法测卵巢癌组织及癌旁组织中GST-π活性,反转录-聚合酶链反应测卵巢癌组织及癌旁组织中GST-π mRNA表达。结果 癌旁组织及Ⅰ、Ⅱ、Ⅲ、Ⅳ期卵巢癌组织中GST-π活性分别为(0.61±0.04)、(1.29±0.13)、(4.01±0.33)、(7.35±0.18)、(8.39±0.41)μmol·mgprot-1·h-1,两两比较差异均有统计学意义(P<0.05);临床分期越高,卵巢癌组织中GST-π活性越强。癌旁组织及Ⅰ、Ⅱ、Ⅲ、Ⅳ期卵巢癌组织中GST-π mRNA表达分别为0.004±0.001、0.051±0.003、0.087±0.004、0.109±0.032、0.165±0.026,两两比较差异均有统计学意义(P<0.05);临床分期越高,卵巢癌组织中GST-πmRNA表达越强。体外药物敏感性试验结果显示,56例标本中,对3种药物联合化学治疗高度敏感者9例(16.07%),中度敏感者17例(30.36%),低度敏感者12例(21.43%),耐药者18例(32.14%)。高度敏感、中度敏感、低度敏感及耐药的卵巢癌组织中GST-π活性分别为(1.61±0.12)、(5.83±1.57)、(8.24±2.23)和(13.49±2.06)μmol·mgprot-1·h-1,两两比较差异均有统计学意义(P<0.05);耐药性越强,卵巢癌组织中GST-π活性越大。结论 GST-π可能参与卵巢癌的多药耐药机制。
Abstract:
Objective To study the role of glutathione S-transferase-π(GST-π) in the multidrug resistance of ovarian cancer.Methods Fifty-six ovarian cancer tissue specimens were selected from January 2013 to December 2015 in Luoyang Central Hospital.Tumor cells cultured in vitro were used to drug sensitivity test by thiazolyl blue(MTT) method.The GST-π activity in ovarian cancer tissues and paracancerous tissues was detected by enzyme linked immunosorbent assay,and the expression of GST-π mRNA in ovarian cancer tissues and paracancerous tissues was detected by reverse transcription-polymerase chain reaction.Results The activity of GST-π in paracancerous tissues and stage Ⅰ,Ⅱ,Ⅲ and Ⅳ ovarian cancer tissues was (0.61±0.04),(1.29±0.13),(4.01±0.33),(7.35±0.18) and (8.39±0.41)μmol·mgprot-1·h-1 respectively;there was significant difference between them(P<0.05).With the higher of clinical stage,the activity of GST-π in ovarian carcinoma was more.The drug sensitivity test in vitro showed that 9 cases(16.07%) were highly sensitive to the three drugs,17 cases(30.36%) were moderately sensitive to the three drugs,and 12 cases were low sensitivity to the three drugs (21.43%),and 18 cases(32.14%) were resistant to the three drugs in the 56 cases.The activity of GST-π in highly sensitive,moderately sensitive,low sensitive and resistant ovarian carcinoma tissues was (1.61±0.12),(5.83±1.57),(8.24±2.23) and (13.49±2.06)μmol·mgprot-1·h-1 respectively;there was significant difference between them(P<0.05).With the stronger of the resistance,the activity of GST-π in ovarian carcinoma was more.Conclusion GST-π may play a role in the multidrug resistance mechanism of ovarian cancer.
