Many cell-surface receptors induce production of second messengers like PIP3, phosphatidylinositol 3,4,5-trisphosphate, that convey signals to the cytoplasm from the cell surface. PIP3 signals activates the kinase PDK1, 3-phosphoinositide-dependent protein kinase-1, which in turn activates the kinase AKT, also known as protein kinase B. Proteins phosphorylated by activated AKT promote cell survival. Phosphorylation o......閱讀全文

在免疫學實驗中,比如WB,IHC,IF等,大家都知道選著好正確的一抗,往往實驗就成功了一大半,因此,往往很多研究者便會忽視對二抗,以及其它試劑盒品質的追求。二抗是一種相對而言比較穩定的產品,包裝大,因此很多實驗室都會公用一個二抗。但如果二抗沒有選擇好的話,影響的可能就是一整個實驗室或者課題組了。艾美

胰腺癌的預后非常差,其致死率基本等同于發病率。在美國,胰腺癌的5年生存率依然只有6%。關鍵的問題是胰腺癌患者在早期基本無癥狀,被診斷發現時大多數都處在晚期;全球每年胰腺癌致死的病人超過20萬人。 胰腺癌有多種類型,基本上劃分成外分泌腫瘤和內分泌腫瘤兩種。99%的胰腺癌都屬于外分泌型腫瘤,其
