Background: Preeclampsia (PE) is a pregnancy specific syndrome that is associated with high maternal and fetal morbidity and mortality. Glucose regulated protein78 (GRP78) is an Endoplasmic Reticulum (ER) protein which is expressed on the cell surfaces of trophoblast cells under stress or hypoxic condition. GRP78 has a role in aggressive behavior of invasive cells and may play a role in normal ...

endoplasmic reticulum has a critical role in the synthesis and folding of secretory and membrane proteins. high accumulation of proteins in er activates the unfolded protein response and glucose regulated protein 78 or gpr78 plays an essential role in this pathway.  unfolded protein response is activated in cancerous cells due to their adverse condition to survive and it has been shown that grp...

Viruses utilize cellular proteins to mediate their life cycle. However, the hepatitis B virus (HBV) cycle is still mysterious and remains be elucidated. Here, GRP78/BiP/HSPA5, a 78 kDa glucose-regulated protein, was identified as preS2 interacting protein. Pulldown assay showed interaction of protein (GRP78) with both domain-containing large S middle expressed in human hepatocellular cell line....

BACKGROUND Identification of biomarkers of cigarette smoke -induced lung damage and early COPD is an area of intense interest. Glucose regulated protein of 78 kD (i.e., GRP78), a multi-functional protein which mediates cell responses to oxidant stress, is increased in the lungs of cigarette smokers and in the serum of subjects with COPD. We have suggested that secretion of GRP78 by lung cells m...

Glucose regulated protein 78 (GRP78) is usually recognized as a chaperone in the endoplasmic reticulum. However, increasing evidence indicates that GRP78 can be translocated to the cell surface, acting as a signaling receptor for a variety of ligands. Since little is known about the secretion of GRP78 and its role in the progression of colon cancer we here focused on GRP78 from colon cancer cel...

BACKGROUND Glucose-regulated protein 78 (GRP78) is highly expressed in first trimester cytrophoblastic cells (CTBs), especially in syncytiotrophoblast (STB). However, the role of GRP78 in these cells has never been investigated. METHODOLOGY/PRINCIPAL FINDINGS In this study, we have examined the role of GRP78 in trophoblast fusion using the Bewo choriocarcinoma cell line as a model of cytotrop...

Apoptosis of alveolar epithelial cells has been implicated in the pathogenesis of chronic obstructive pulmonary disease. To determine the involvement of glucose‑regulated protein 78 (GRP78) in the cigarette smoke extract (CSE)‑induced apoptosis of alveolar epithelial cells and the potential mechanisms underlying this effect, A549 cells that originate from alveolar type II epithelial cells were ...
