death pathway

death pathway

finding that characterizes a protein that initiates final stage of cell death known as apoptosis. Mammalian families of proteins that execute the apoptotic pathway are Bcl-2, Apaf-1, and caspase-3. FAS receptor-ligand system is a regulator of apoptotic cell death.

Autophagy in response to cellular stress states serves as a potent death signal, as in the case of chemotherapy-induced autophagy, a specific non-apoptotic death pathway has been triggered off.
By preventing cell-to-cell transmission, we may able to block the death pathway and stop the progression from HIV infection to AIDS.
Preclinical studies suggest that TREANDA may lead to cell death by a process known as apoptosis (programmed cell death) as well as by an alternate cell death pathway which disrupts normal cell division known as mitotic catastrophe (a non-apoptotic pathway).
Therefore, JNK is required for stress-induced activation of the cytochrome c-mediated death pathway (Tournier et al.
Prof Patrick Pullicino, a consultant neurologist, told the Daily Mail: "The lack of evidence for initiating the Liverpool Care Pathway makes it an assisted death pathway rather than a care pathway.
The researchers identified a novel receptor-mediated death pathway in breast cancer cells specifically targeted by MDA-7.
This dephosphorylation relieves repression, allowing genes in a death pathway to be transcribed, leading to lysis of the bacteria.
We are all looking for a unifying theme that might funnel all these different models into a common death pathway," says Hockenbery, He and his co-workers speculate that - no matter what the specific death signal or cell type - once a cell is bent on dying, it does so via free radicals, turning loose a chain of ruinous chemical reactions that bcl-2 can counter.
In response to the stress, beta cells activate a cell death pathway leading to the loss of beta cell mass in the animal.
The surprising aspect is that caspase 8 appears to have two functions: one that initiates apoptosis and a second that restrains an independent programmed death pathway," says senior author Ed Mocarski.
Tumor profiling also showed a lack of PD-L1 (tumor infiltrating lymphocytes), which suggested to investigators that immune therapies targeting the programmed death pathway may not be useful in SCCC.
