The main method of treatment for potential death from signaling-related diseases involves either increasing or decreasing the susceptibility of apoptosis in diseased cells, depending on whether the disease is caused by either the inhibition of or excess apoptosis. For instance, treatments aim to restore apoptosis to treat diseases with ...
Inhibitors of apoptosis are a group of proteins that mainly act on the intrinsic pathway that block programmed cell death, which can frequently lead to cancer or other effects for the cell if mutated or improperly regulated. Many of these inhibitors act to block caspases, a family of cysteine proteases that play an integral role in apoptosis. [1]
PI3K/ AKT/mTOR pathway is a central regulator of ovarian cancer. PIM kinases are over expressed in many types of cancers and they also contribute to the regulation of ovarian cancer. PIM are directly and indirectly found to activate mTOR and its upstream effectors like AKT. Besides, PIM kinases can cause phosphorylation of IRS, which can alter ...
Mutations of the cell pathway can either promote cell death or disallow cell death creating a huge amount of disease in the body. Mutated apoptosis pathways causing disease are plentiful and have a wide range from cancer, due to lack of apoptosome activity, Alzheimer's disease due to too much apoptosome activity, and many other ...
Overview of signal transduction pathways involved in apoptosis. Cell death is the event of a biological cell ceasing to carry out its functions. This may be the result of the natural process of old cells dying and being replaced by new ones, as in programmed cell death, or may result from factors such as diseases, localized injury, or the death of the organism of which the cells are part.
While apoptosis often provides beneficial effects to the organism, necrosis is almost always detrimental and can be fatal. [ 3 ] Cellular death due to necrosis does not follow the apoptotic signal transduction pathway, but rather various receptors are activated and result in the loss of cell membrane integrity [ 4 ] and an uncontrolled release ...

cIAP1 is an inhibitor of apoptosis protein. It directly ubiquitinates RIP1 and induces constitutive RIP1 ubiquitination in cancer cells. Ubiquinated RIP1 associates with the prosurvival kinase TAK1. When this complex is deubiquinated apoptosis is induced. [10] [11] The absence of cIAP1 means that RIP1 will remain nonubiquitinated.
