Anal Cell Pathol:研究阐明 MIR4697HG在卵巢癌生长及转移中的作用

2017-09-01 MedSci MedSci原创

卵巢癌是世界上最常见的三大妇科恶性肿瘤之一。由于治疗策略的限制,这种恶性肿瘤患者的预后仍然很差。本研究中,研究人员探究了了一种长链非编码RNA (MIR4697HG)在卵巢癌细胞生长与转移中的作用。结果表明,癌组织中MIR4697HG的转录水平较癌旁组织增加了一倍。卵巢癌细胞系中MIR4697HG的表达不同,OVCAR3 和 SKOV3细胞中表达水平最高。通过特定的shRNA敲除MIR4697HG

卵巢癌是世界上最常见的三大妇科恶性肿瘤之一。由于治疗策略的限制,这种恶性肿瘤患者的预后仍然很差。本研究中,研究人员探究了了一种长链非编码RNA (MIR4697HG)在卵巢癌细胞生长与转移中的作用。

结果表明,癌组织中MIR4697HG的转录水平较癌旁组织增加了一倍。卵巢癌细胞系中MIR4697HG的表达不同,OVCAR3 和 SKOV3细胞中表达水平最高。通过特定的shRNA敲除MIR4697HG能显著抑制OVCAR3 和 SKOV3细胞的增殖和集落形成。同样地,在卵巢癌移植瘤模型中,删除MIR4697HG也能明显限制肿瘤的体积和重量。此外,MIR4697HG敲除还可抑制细胞的迁移和侵袭能力。MIR4697HG敲除后,侵袭能力方面,可分别降低OVCAR3细胞和SKOV3细胞的40%和58%;迁移能力方面,可分别降低OVCAR3细胞和SKOV3细胞的62%和73%。MIR4697HG敲除还可降低基质金属蛋白酶-9、磷酸化ERK以及磷酸化AKT的水平。

总之,这些数据表明,MIR4697HG可促进卵巢癌的生长和转移。卵巢癌中MIR4697HG的侵袭力或与ERK和AKT信号通路相关。

Int J Cancer:痛经会导致卵巢癌风险增加

痛经是一种常见的妇科疾病,指行经前后或月经期出现下腹部疼痛、坠胀,伴有腰酸或其他不适,症状严重影响生活质量者。痛经分为原发性痛经和继发性两类,原发性痛经指生殖器官无器质性病变的痛经,占痛经90%以上;继发性痛经指由盆腔器质性疾病引起的痛经。在既往的研究中,部分研究的结果表明它与女性患卵巢癌的风险相关,但并非所有的研究都如此。此外,由于缺乏动力,痛经和卵巢癌的不同组织学亚型之间的潜在变化还没有得到充

新剂型,新适应症!奥拉帕尼获批二线维持治疗卵巢癌

阿斯利康8月17日宣布,FDA扩大批准Lynparza(奥拉帕尼,PARP抑制剂)片剂用于对铂类药物化疗有应答的成人卵巢上皮癌、输卵管癌和原发性腹膜癌患者的二线维持治疗。

J CLIN ONCOL:延长无铂间期能否为铂类部分敏感的卵巢癌患者带来生存获益?

对于无铂间期(PFI)6至12个月的卵巢癌复发患者,临床上通过引入非铂药物来延长PFI并增加患者对铂类药物的敏感性。但是由Sandro Pignata教授主导于2017年8月21日发表在JOURNAL OF CLINICAL ONCOLOGY上的MITO-8研究则发现,这种治疗策略并不使对铂类药物部分敏感的卵巢癌患者取得生存获益。

Oncotarget:老标记新功能,血清CA125浓度预测卵巢癌转移

卵巢恶性肿瘤是女性生殖器官常见的恶性肿瘤之一,对妇女生命造成严重威胁。由于卵巢的胚胎发育、组织解剖及内分泌功能较复杂,早期症状不典型,术前鉴别卵巢肿瘤的组织类型及良恶性相当困难。

Int J Cancer:抗抑郁药或能降低卵巢上皮癌的风险

卵巢上皮癌是常见的妇科恶性肿瘤,占卵巢肿瘤的;50%-70%.由于EOC早期(I、II期)缺乏典型临床表观。76%的病人在发现时已有腹腔内种植,肝实质和/或胸腔、颅内转移(III、IV期)这是导致较高病死率的主要原因。 抗抑郁药治疗在女性中被广泛使用,主要治疗抑郁症和焦虑症,但目前很少有研究探讨抗抑郁药对妇科癌症风险的影响。
