GRP78/BiP, HSPA5: Click to Expand ⟱

Type:
GRP78 (Pgp, BiP or ERp72) is a central regulator of endoplasmic reticulum (ER) function due to its roles in protein folding and assembly, targeting misfolded protein for degradation, ER Ca(2+)-binding and controlling the activation of trans-membrane ER stress sensors.
-GRP78 protein, a marker for endoplasmic reticulum stress
-GRP78’s role as a master regulator of the unfolded protein response (UPR) and cellular stress responses
The association of P-gp and inhibition of cell death in cancerous cells has also been reported in several studies including in hepatocellular, colorectal, prostate cancer, and gastric cancer. Although counterintuitive due to its prominent role in cancer resistance, P-gp has been linked to favorable prognosis.
ERp72 can promote cancer cell proliferation, migration, and invasion by regulating various signaling pathways, including the PI3K/AKT and MAPK/ERK pathways. Additionally, ERp72 can also inhibit apoptosis (programmed cell death) in cancer cells, which can contribute to tumor progression. Overexpressed in: Breast, lung colorectal, prostrate, ovarian, pancreatic.

-GRP78 is frequently upregulated in a variety of solid tumors and hematological malignancies.
-Overexpression of GRP78 in cancer cells is often regarded as a marker of increased ER stress due to the reduced oxygen and nutrient supply typically encountered in the tumor microenvironment.
-Elevated GRP78 levels can contribute to tumor cell survival by enhancing the adaptive UPR, allowing cancer cells to cope with therapeutic and metabolic stress.
