Apoptosis or Programmed Cell Death

Words: 1722 Pages: 6 3967

Apoptosis is an important cellular process that allows cells to die in a programmed and organized fashion. This form of programmed cell death is crucial to the stability and equilibrium of living organisms. Such a process is shared amongst vertebrates and invertebrates alike (Miguel-Aliaga et al., 2009). It is easiest to define “normal” development by […]

Diffuse Intrinsic Pontine Gliomas

Words: 3372 Pages: 11 3694

Introduction/Epidemiology A diffuse intrinsic pontine glioma (DIPG), is a malignant tumor of the pons of the brainstem that originates in the supportive tissue called the glia. Specifically, these tumors are diffuse astrocytomas meaning that the tumor develops from astroglial cells of the brain stem. This tumor accounts for about 10%-20% of all brain tumors in […]

Journal Article for Review: Apoptosis-induced CXCL5

Words: 1435 Pages: 5 3737

The article under review examines the acceleration of inflammation and growth of prostate tumor metastasis in bone due to apoptosis-induced CXCL5. Tumor cell death, which can be increased by target therapies, causes immense efferocytosis to clear the apoptotic cells. It is thought that this can lead to accelerated tumor growth. The scope of this research […]

Necrosis Cell Death

Words: 306 Pages: 1 3646

Necrosis is classified as a disorganized cell death process in response to disease, cell injury, or lack of sufficient blood supply.

Degradation of Glycogen and Necrotic Cell Death

Words: 662 Pages: 2 3405

PYGL (glycogen phosphorylase) catalyzes degradation of glycogen and therefore allows it to be used as an energy source. The researchers were unable to obtain PYGL antibodies to further study the RIP3/PYGL interaction in necrosis. However, the interaction was induced by TNF but not zVAD. They incubated flag RIP3 missing glutathione S-transferase, which did not enhance […]

Essay about Resistance to Stress

Words: 480 Pages: 2 3381

Caloric restriction extends longevity in yeast because the absence of Tor/Sch9 signaling causes a metabolic change that uses acetic acid, which is similar to the generation and use of ketone bodies, acetoacetic acid, and lower than that of glucose (Wei et al., 2009). High levels of acetic acid promotes apoptosis in yeast and is the […]

Facts about Cells

Words: 333 Pages: 1 4133

All living cells will eventually decay and die. There are two recognized types of cell death: apoptosis and necrosis. Apoptosis refers to the “self-destruction” of a cell by its own mechanisms.

How Cells Cheat Death

Words: 633 Pages: 2 4282

Cells are constantly fighting between life and death. It is believed that once cells go through certain incidences, their death is irreversible.
