凋亡聚焦：選擇合適的TUNEL分析
考慮檢測方法 TUNEL分析一般采用顯色法或熒光檢測法。每一種都有其各自的優缺點，因此選擇哪一種取決于您的需求。熒光檢測感更為靈敏，但難以保留信號。由于成像時的光漂白，且隨著時間的流逝，熒光信號會逐漸喪失。熒光信號也會有更高的背景問題，這要取決于組織類型。顯色分析適用于組織切片，因為可以使

細胞凋亡檢測方法介紹
細胞凋亡是指細胞在生長到一定階段及某些生理過程中，會受到多因素和機制的嚴格調控而進入死亡。這是一個動態的過程,會涉及一系列復雜的生化反應, 是一個需要酶參與的級聯反應,同時也涉及不同基因的表達及調控、信號傳導。其中有幾項生理過程能被用來檢測凋亡的發生，因此多參數分析法對于準確檢測這一過程十分

Cell－Death－Differ：前列腺癌惡化標志
前列腺癌是近年來導致西方國家男性死亡的嚴重癌癥之一，擴散性疾病的患者治療情況也不夠樂觀。血清中的前列腺特意抗原（PSA）是用于癌癥檢測的分子標記，但是對于癌癥的惡化PSA并不能夠達到準確的預測，因此找到一個更加合適的分子標記對于前列腺癌的中期診斷十分重要。另一方面，由于前列腺癌的異質性，至今還沒

同濟大學毛志勇教授發表Cell－Death－－Differentiation文章
基因組穩定性下降是生物體衰老發生極其重要的一個標志。細胞長期在各種因素的影響下，DNA遭受著多種損傷，若這些損傷不被及時準確地修復將誘發基因組穩定性的下降，進而影響細胞的正常生命活動。這些損傷中，DNA雙鏈斷裂（DSBs）是最為嚴重的基因組損傷之一。近年來，雖然關于DNA DSBs修復與衰老發
