Grp78 (Glucose Regulated 78kDa Protein), is also known as BiP or Immunoglobulin heavy chain binding protein. It is a stressresponse protein which is induced by agents or conditions that adversely affect endoplasmic reticulum (ER) function. This protein is essential for the proper glycosylation, folding, and assembly of many membrane bound and secreted proteins as well as for maintenance of cell homeostasis and the prevention of apoptosis.

Western blot analysis: Lane 1: MW marker, Lane 2: 150 ng of Grp78 (BiP) recombinant protein (Prod. No. ADI-SPP-765), Lane 3: 20µg of CHO-K1 cell lysate, Lane 4: 20µg of mouse liver microsome tissue extract (Prod. No. ADI-LYT-MM100).

Induction of UPR (A,C) and autophagy genes (B,D) by L1000-ER/UPR/autophagy drugs. Cultured GECs were incubated for 24 h with drugs (10 μM concentrations). In panel B, drugs were added together with CQ, as indicated. Lysates were immunoblotted, as indicated. (A,B) Representative immunoblots. (C–E) Densitometric quantification (the expression of each protein is normalized to actin). *p < 0.05, **p < 0.01, +p < 0.001, ++p < 0.0001 vs. untreated. Mean ± SE, 3 experiments performed in duplicate. (E) Autophagosomal flux, as determined by the level of LC3-II in the presence of chloroquine (densitometric quantification of specific lanes in panel B). *p < 0.05, **p < 0.01, vs. chloroquine. Tunicamycin and rapamycin are stimulators of the UPR or autophagy (positive controls). Untr, untreated; Tunic, tunicamycin, Gel, geldanamycin; Rad, radicicol; NVP, NVP-AUY922; Ner, neratinib; Rap, rapamycin; CQ, chloroquine.
