CellCycle:G1／SCheckPoint
The G1/S cell cycle checkpoint controls the passage of eukaryotic cells from the first 'gap' phase (G1) into the DNA synthesis phase (S). Two cell cycle kinases, CDK4/6-cyclin D and CDK2-cyclin E, and the transcription complex that includes Rb and E2F are pivotal in controlling this checkpoint. During G1 phase, the Rb-HDAC repressor complex binds to the E2F-DP1 transcription factors, inhibiting the downstream......閱讀全文

Cell－Cycle：細胞永生化研究進展
每一天，你身體內的一些細胞會停止分裂，這是一件好事。而有些細胞會無限增殖，這是大多數惡性腫瘤發展的一個重要早期步驟。 盡管細胞無限增殖在癌癥中有著非常的重要性，但研究人員一直對于細胞永生化背后的分子機制知之甚少。這是因為科學家缺乏好方法研究永生化人類細胞。在發表在Cell Cycle 雜志上的
Cell－Cycle－－J－Neurosci：脊髓損傷引發大腦損害
很多脊髓損傷的研究都集中于揭示脊髓損傷所引發的效應，然而往往在研究中科學家們很容易忽視脊髓損傷對大腦所引發的效應。近日，來自馬里蘭大學的研究人員通過研究首次揭示，脊髓損傷（SCI）可以促進廣泛和持續的大腦炎癥，進而引發神經細胞的逐漸缺失以及認知問題和抑郁癥等。 相關研究發表于國際雜志Journ
