Apoptosis as a conserved pathway Intrinsic and extrinsic pathways of apoptosis What is the difference between intrinsic and extrinsic pathway of apoptosis? There are at least two broad signaling pathways that lead to apoptosis: the intrinsic pa...
The extrinsic pathway begins outside a cell, when conditions in the extracellular environment determine that a cell must die. The intrinsic apoptosis pathway begins when an injury occurs within the cell. The injury could result in necrosis and produce an inflammatory response, but the apoptotic ...

“Extrinsic Pathway” “Intrinsic Pathway” MAJOR PLAYERS IN APOPTOSIS • Caspases • Adaptor proteins • TNF & TNFR family • Bcl-2 family Ligand-induced cell death Ligand Receptor FasL Fas (CD95) TNF TNF-R TRAIL DR4 (Trail-R) ...
Furthermore, RT-PCR analysis showed that harmine induced apoptosis in B16F-10 melanoma cells by up-regulating Bax and activating Caspase-3, 9 and p53 and down-regulating Bcl-2. Harmine also up-regulated Caspase-8 and Bid, indicating that harmine affected both extrinsic and intrinsic pathways...
细胞凋亡(Apoptosis)细胞凋亡的概念：由体内外因素触发、由基因严格调控而发生的自主性细胞有序死亡.细胞凋亡的特点：①细胞通过出芽的方式形成许多凋亡小体；②凋亡小体内有结构完整的细胞器；③溶酶体活性不增加④内切酶活化，DNA片断化，凝胶电泳图谱呈梯状 ProceduresofApoptosis Overview:ProgrammedCellDeathandNo...
Treatment of P388D1, a macrophage-like cell line, with staurosporine triggered apoptosis through the activation of caspase-9 and caspase-3. Unexpected effects of staurosporine on the induction of apoptosis were the activation of caspase-8, and an increase of the levels of TNF-. The increased ...
1, 2 Evasion of apoptosis (programmed cell death) is a hallmark of glioblastoma that promotes tumorigenesis and progression, as well as treatment resistance.3, 4 The two key signaling pathways of apoptosis comprise the extrinsic (death receptor) pathway and the intrinsic (mitochondrial) pathway.3 ...
pathways have been described: the extrinsic pathway, which is initiated by the tumor necrosis factor (TNF)/nerve growth factor (NGF) receptors superfamily [7–11], and the intrinsic pathway, which include the mitochondrial pathway, the endoplasmic reticulum pathway and the DNA damage pathway [12...
The apoptotic response of cells can be induced by the intrinsic and the extrinsic pathway, the former being mediated by the mitochondria and the latter activated by ligand stimulation of death receptors at the cell surface [1]. Death receptor ligands such as tumor necrosis factor-related apoptosis...
