We found that downregulation of GRP78 led to inhibition of autophagy, cell cycle arrest in the G0/G1 phase, and activation of caspase-7-induced apoptosis, and this was affected by the initial autophagy level.
GRP78 promotes cigarette smoke-induced inflammatory response and mucus hyperproduction in airway epithelial cells, likely through upregulation of necroptosis and subsequent activation of NF-kappaB and AP-1 pathways.
Data suggested that GRP78 silencing increased chemo-sensitivity and improved the effects of cisplatin-induced apoptosis in SiHa cells. Moreover, inhibition of GRP78 could upregulate caspase-3 and CHOP expression and downregulate Bcl-2 expression.
Upon IgM expression, its levels temporarily eclipse those of the endoplasmic reticulum chaperone BiP, leading to acute, full-geared unfolded protein response activation. Once BiP is in excess again, the unfolded protein response transitions to chronic, submaximal activation, indicating that the unfolded protein response senses endoplasmic reticulum stress in a ratiometric fashion.
GRP78 binds to and acts in concert with a glycosylphosphatidylinositol-anchored protein, CD109, in blocking TGF-beta signaling by promoting the routing of the TGF-beta receptor to the caveolae, thereby disrupting its binding to and activation of Smad2.
this study demonstrates the reaction of placental GRP78 with sera from women with multiple sclerosis
This meta-analysis shows that BiP or anti-BiP antibodies have a moderate accuracy for the diagnosis of rheumatoid arthritis with a moderate sensitivity and high specificity. It can be an efficient supplement to the existing diagnostic method. [Meta-Analysis]
the expression of three cytokines for the pathogenesis of osteoarthritis (OA). which include IL-1beta, MMP14 and GRP78 was decreased by the various concentrations of icariin. These preliminary results imply that icariin might be an effective compound for the treatment of OA disease.
In a retrospective cervical cancer cohort, high GRP78 expression was correlated with poor survival. miR-181a suppressed cervical cancer development via downregulating GRP78.
We revealed that DAL-1 was downregulated while HSPA5 was upregulated in NSCLC and found the protein of DAL-1 and HSPA5 co-localized in the cytoplasm and nucleus. We demonstrated that DAL-1 can suppress the expression of HSPA5 on mRNA and protein levels, and decrease EMT, migration, invasion and proliferation abilities by down-regulating HSPA5
We found that inhibiting the function of surface GRP78 suppressed cancer cell survival and growth proving that the surface-expressed GRP78 is a vital receptor involved in the proliferation of high-grade glioma.
BiP/GRP78 is significantly associated with tumor aggressiveness and progression. The increased expression of BiP/GRP78 was identified as an independent factor for predicting poor OS in patients with early stage of disease.
This paper reports the localization of both GRP78 and HSP60 on the luminal/apical surface of oviduct epithelial cells, their binding to spermatozoa, and the presence of endogenous HSP60 in the sperm midpiece.
BiP is a master regulator of endoplasmic reticulum function, and its cleavage by subtilase cytotoxin represents a previously unknown trigger for cell death
Over-expression of GRP78 enhances replication of Porcine Circovirus 2.
GRP78 regulates insulin resistance and macrophage polarization with selective IL-6 secretion in diet-induced obesity.
Data suggest that endoplasmic reticulum stress-induced CHOP/Ddit3 inhibits expression of Bip/Grp78 and Atf4; ATF4, in turn, plays critical role in CHOP-mediated regulation of B-cell receptor-controlled murine gammaherpesvirus-68 lytic replication. (CHOP/Ddit3 = DNA-damage inducible transcript-3; Bip/Grp78 = chaperone BiP 78 kDa; Atf4 = activating transcription factor-4)
These results uncover a novel role of GRP78 in reducing prion pathogenesis, suggesting that modulating its levels/activity may offer a novel opportunity for designing therapeutic approaches for these diseases.

Data suggest that activation of GRP78/Ire1/Xbp1 pathway of ER stress-unfolded protein response is involved in mouse decidualization.
Upregulating HSF1 relieves the tau toxicity in N2a-TauRD DeltaK280 by reducing CHOP and increasing HSP70 a5 (BiP/GRP78). Our work reveals how the bidirectional crosstalk between the two stress response systems promotes early tau pathology and identifies HSF1 being one likely key player in both systems.

The protein encoded by this gene is a member of the heat shock protein 70 (HSP70) family. It is localized in the lumen of the endoplasmic reticulum (ER), and is involved in the folding and assembly of proteins in the ER. As this protein interacts with many ER proteins, it may play a key role in monitoring protein transport through the cell.
