FoxO3 Inactivation Promotes Human Cholangiocarcinoma Tumorigenesis and Chemoresistance through Keap1-Nrf2 Signaling [PDF]
, 2016 许多人类肿瘤中存在PI3K/AKT过度激活，然而该通路的异常导致肿瘤形成的分子机理仍未充分阐明。FoxOs是受PI3K/AKT负向调控的转录因子，与肿瘤形成密切相关，但对于FoxOs调控肿瘤生长的机制尚不十分清楚。胆管癌是一类起源于胆道上皮细胞的恶性肿瘤，胆管癌患者对化疗敏感性差，但耐药机理尚未充分阐明。Nrf2的激活与胆管癌耐药性及病人不良预后密切相关。高度激活的PI3K/AKT能够激活Nrf2信号通路，但其中具体的分子机制尚不清楚。Keap1是连接Nrf2与Cul3的衔接蛋白 ...

Involvement of Abnormal MicroRNA Expression in the Mechanism of Drug Resistance with Acute Myeloid Leukemia [PDF]
, 2016 目的：分析miRNA-98的表达异常在急性髓系白血病化疗耐药机制的作用，通过靶向过表达miRNA-98的表达水平探讨以miRNA-98为靶点增加化疗药物敏感性的可能性并分析其可能作用的机制。评价异常表达的血清miRNA-155是否可作为急性髓系白血病的预后标志。 方法：离体实验中，采用qRT-PCR方法检测K562和其耐药株K562/A02中miR-98、E2F1基因表达情况。通过瞬时转染miR-98mimic处理耐药细胞K562/A0248h后，通过qRT-PCR法检测miR-98表达情况；通过qRT-

Study on the mechanisms of Pygopus-2 promoting invasion and metastasis in hepatocellular carcinoma [PDF]
, 2016 第一部分Pygopus-2在HCC中高表达与病人恶性预后密切相关 Pygopus-2是经典Wnt/β-Catenin信号通路转录复合体的重要成分。本研究目的是观察在原发性肝癌中Pygopus-2的表达情况及相关的临床病理意义。RT-PCR的方法检测50对肝癌病人组织标本中癌组织与癌旁组织中Pygopus-2的mRNA表达情况，结果发现癌组织中Pygopus-2的mRNA水平明显高于癌旁组织(P=0.009)。免疫组化分析显示异常表达的Pygopus-2蛋白与肝癌病人的年龄(P=0.025)、肿瘤大小(P=
