GRP78: A cell's response to stress.

08:00 EDT 9th April 2019 | BioPortfolio

Summary of "GRP78: A cell's response to stress."

Glucose-Regulated Protein 78 (GRP78) is a chaperone heat shock protein that has been intensely studied in the last two decades. GRP78 is the master of the unfolded protein response (UBR) in the Endoplasmic Reticulum (ER) in normal cells. GRP78 force the unfolded proteins to refold or degrade using cellular degradation mechanisms.

GRP78 expression in tumor and perinephric adipose tissue is not an optimal risk stratification marker for clear cell renal cell carcinoma.

Clear cell renal cell carcinoma (ccRCC) is the most common subtype of kidney cancer, which is difficult to treat and lacks a reliable prognostic marker. A previous study showed that the endoplasmic re...

AAV2-mediated GRP78 Transfer Alleviates Retinal Neuronal Injury by Downregulating ER Stress and Tau Oligomer Formation.

Retinal ganglion cell (RGC) death following axonal injury occurring in traumatic optic neuropathy (TON) causes irreversible vision loss. GRP78 is a molecular chaperone that enhances protein folding an...

Pharmacological effectors of GRP78 chaperone in cancers.

The protein chaperone GRP78 is a master regulator of endoplasmic reticulum (ER) functions and is frequently over-expressed at the surface of cancer cells where it contributes to chemo-resistance. It r...

Effect of brilliant Blue-G on cellular stress response in retinal pigment epithelial cells: In vitro.

To assess the cellular stress evoked by exposure of Brilliant Blue-G (BBG), adult retinal pigment epithelial (ARPE-19) cells were treated with various dilutions of BBG in balanced salt solution plus (...

Involvement of endoplasmic reticulum stress in regulation of endometrial stromal cell invasiveness: Possible role in pathogenesis of endometriosis.

Endoplasmic reticulum (ER) stress is known to reduce invasiveness in some cancer cells by inhibiting the AKT/mTOR pathway. A previous study from our laboratory suggested that ER stress is promoted by ...

Medical and Biotech [MESH] Definitions

One of the BASIC-LEUCINE ZIPPER TRANSCRIPTION FACTORS that is synthesized as a membrane-bound protein in the ENDOPLASMIC RETICULUM. In response to endoplasmic reticulum stress it translocates to the GOLGI APPARATUS. It is activated by PROTEASES and then moves to the CELL NUCLEUS to regulate GENETIC TRANSCRIPTION of GENES involved in the unfolded protein response.

A growth differentiation factor that is secreted in response to cell stress and in response to MACROPHAGE ACTIVATION. In addition growth differentiation factor 15 demonstrates a diverse array of biological properties including the induction of cartilage formation, the inhibition of hematopoietic progenitor proliferation, and the induction of neuronal migration.

A forkhead box transcription factor that is a major target of INSULIN signaling and regulator of metabolic homeostasis in response to OXIDATIVE STRESS. It binds to the insulin RESPONSE ELEMENT (IRE) and the related Daf-16 family binding element (DBE). Its activity is suppressed by insulin and it also regulates OSTEOBLAST proliferation, controls bone mass, and skeletal regulation of GLUCOSE metabolism. It promotes GLUCONEOGENESIS in HEPATOCYTES and regulates gene expression in ADIPOSE TISSUE. It is also an important CELL DEATH regulator. Chromosomal aberrations involving the FOXO1 gene occur in RHABDOMYOSARCOMA.

A serine/threonine-specific protein kinase which is encoded by the CHEK1 gene in humans. Checkpoint kinase 1 (also known as Chk1) coordinates DNA damage response and cell cycle checkpoint response. Under these conditions, activation of Chk1 results in the initiation of cell cycle checkpoints, cell cycle arrest, DNA repair and cell death, to prevent damaged cells from progressing through the cell cycle.

A class of traumatic stress disorders that is characterized by the significant dissociative states seen immediately after overwhelming trauma. By definition it cannot last longer than 1 month, if it persists, a diagnosis of post-traumatic stress disorder (STRESS DISORDERS, POST-TRAUMATIC) is more appropriate.
