Cells may also die as direct consequences of viral infections. HIV-1 expression induces tubular cell G2/M arrest and apoptosis. [104] The progression from HIV to AIDS is not immediate or even necessarily rapid; HIV's cytotoxic activity toward CD4+ lymphocytes is classified as AIDS once a given patient's CD4+ cell count falls below 200.

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.
When these cells have accomplished these tasks, the immune system clears them away. This phenomenon is termed acute senescence. [30] Senescence of hepatic stellate cells could prevent progression of liver fibrosis, although this has not been implemented as a therapy, and would carry the risk of hepatic dysfunction. [74]
In HeLa cells, DDX3X is reported to control cell cycle progression through Cyclin E1. [12] More specifically, DDX3X was shown to directly bind to the 5´ UTR of Cyclin E1, thereby facilitating the protein's translation. Increased protein levels of Cyclin E1 were demonstrated to mediate the transition of S phase entry. [12]
Signs of death or strong indications that a human is no longer alive are: Respiratory arrest (no breathing); Cardiac arrest (no pulse); Brain death (no neuronal activity); The heart and lungs are vital organs for human life due to their ability to properly oxygenate human blood (lungs) and distribute this blood to all vital organs (heart).
The different stages of mitosis all together define the M phase of an animal cell cycle—the division of the mother cell into two genetically identical daughter cells. [3] To ensure proper progression through the cell cycle, DNA damage is detected and repaired at various checkpoints throughout the cycle.
The 407 residue, [15] 46 kDa, [18] protein eIF4A is the prototypical member of the DEAD box helicase family, so-called due to their conserved four-residue D-E-A-D sequence. This family of helicases is found in a range of prokaryotic and eukaryotic organisms including humans, wherein they catalyse a variety of processes including embryogenesis ...
