Concomitant high expression of ERalpha36, GRP78 and GRP94 is associated with aggressive papillary thyroid cancer behavior and may be used as a predictor for extrathyroid extension, lymph node metastasis, and distant metastasis.
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 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.
Endoplasmic reticulum stress leads to de novo biosynthesis of non-trimethylated GRP78, whereas homeostatic, METTL21A-dependent lysine 585-trimethylated GRP78 is reduced.

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.
These results demonstrate a key role for GRP78 in alveolar epithelial cell survival.

Phosphatidylinositol deficient zebrafish have elevated hspa5 expression in the liver and hepatic lipid accumulation due to endoplasmic reticulum stress response.
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.
