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 ...

The role of hedgehog pathway and autophagy in the mechanism of acquired chemoresistance in multiple myeloma [PDF]
, 2015 在多发性骨髓瘤的临床治疗中，化疗耐药现象仍然是治疗失败的主要原因之一。为了更好地了解多发性骨髓瘤的化疗耐药性及相关的机制，我们建立了阿霉素(doxorubicin,DOX)耐药的细胞系多发性骨髓瘤细胞系RPMI8226/R（doxorubicin-resistantcellline），DOX对8226/R的半数抑制率(IC50)是对DOX敏感的细胞系RPMI8226/S（chemosensitivecellline）的5~6倍。我们发现在多发性骨髓瘤耐药性的诱导过程中存在Hedgehog(Hh ...

The new electrochemical DNA sensor for detection of Mycobacterium tuberculosis and its drug resistance gene [PDF]
, 2016 耐药结核分枝杆菌，尤其是耐多药结核分枝杆菌的出现给结核病的检测和治疗带来了巨大的挑战，对人类健康产生了极大威胁。目前临床上常用的结核病的检测方法分别存在操作繁琐、仪器昂贵、耗时较长及易污染等不足。电化学DNA传感器是近几年发展起来的一种新型生物传感器，因其简单、灵敏、特异性强、易微型化等特点受到研究者的青睐，已被应用于多个领域的研究。然而电化学DNA传感器易受其他因素的干扰造成结果不稳定。实验前期构建的BSA单分子层控制组装界面为基础的电化学DNA传感器，有效地提高了体系的稳定性。本文在前期研究基础上 ...
