Effects of stable polymeric immunoglobulin receptor (pIgR) overexpression on endoplasmic reticulum (ER) stress markers evaluated by immunoblotting. Whole cell lysates were resolved by sodium dodecylsulfate–polyacrylamide gel electrophoresis, and blots were incubated with anti-pIgR, calreticulin, BIP and NOTCH3 antibodies. Expression levels of these proteins were normalised to actin. pIgR overexpression did not affect the expression of the ER stress markers calreticulin and BIP, but decreased NOTCH3 expression. FL: full length; ICD: intracellular domain.
