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

Cell－Death－Dis：中風患者遭受腦損傷的新機制
近日，研究人員發現中風患者遭受腦損傷的機制，并正在尋找藥物來阻止它。 當供應到大腦的血液被部分切斷時中風發生，但對于存活者而言更嚴重的傷害是記憶和其他認知功能傷害，這些記憶和其他認知功能傷害常常實際上由血液供應恢復后的幾小時或幾天內“氧化應激”生成過多所引起的。 從Leeds大學和
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

暴露于遺傳毒性應激可促進細胞周期停滯和DNA修復或凋亡。這些“生”或“死”細胞命運的決定通常取決于腫瘤抑制基因53的活性。因此，對p53的精確調控對于維持組織內環境平衡和防止腫瘤的發展至關重要。然而，細胞周期進程是如何影響p53細胞命運的，目前尚不清楚。 已經提出了幾種機制來解釋dna損傷細胞

Cell－Death－Differ：啟動肺癌細胞自毀開關的新療法
近日，英國癌癥研究中心科學家們發現了一種藥物組合，可以觸發肺癌細胞的自毀過程，此項研究為新型治療方法開發鋪平了道路。 當健康細胞對機體不再有用，它們便引發一連串事件最終導致自我毀滅。但癌細胞則突然轉向遠離這個“自殺道路”，成為不朽，這意味著細胞生長失控，引起腫瘤的形成。 現在，英國癌癥研究中

cell－death－－disease:－黑色素瘤抗壞死效應分子機制
RIPK1與RIPK3被發現是參與細胞壞死性凋亡的關鍵成員，在caspase家族活性被抑制的情況下，RIPK1激活后能夠與下游的RIPK3結合形成壞死小體，幫助RIPK3激活（磷酸化）。磷酸化后的RIPK3再次將MLKL磷酸化，磷酸化后的MLKL能夠在細胞膜內側自聚合形成寡聚體，最終導致細胞壞死
