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=

Identifying predictors of translocation success in rare plant species
Conservation Biology, Volume 38, Issue 2, April 2024.Abstract The fundamental goal of a rare plant translocation is to create self‐sustaining populations with the evolutionary resilience to persist in the long term. Yet, most plant translocation syntheses focus on a few factors influencing short‐term benchmarks of success (e.g., survival and reproduction).
