Fig. 1From: Secretion of the endoplasmic reticulum stress protein, GRP78, into the BALF is increased in cigarette smokers a and b. GRP78 is present in BALF from smokers and never smokers. a Western blot showing GRP78 in BALF samples from never smokers (NS) and smokers (S). Recombinant GRP78 (rGRP78) is shown for quantitation (300Â ng). b Individual values of BALF GRP78 in never smokers (NS, n = 11) and healthy smokers (S, n = 13). Mean GRP78 (horizontal bars) was significantly greater in smokers versus never smokers (p = 0.04)Back to article page
