Measuring the impact of cigarette smoke on the UPR.

The unfolded protein response (UPR) is a set of pathways activated by the accumulation of improperly folded proteins. It can be triggered by a broad range of stressful conditions which disrupt successful maturation of proteins in the endoplasmic reticulum (ER) by interfering with proper folding, assembly, and posttranslational modification. Recent studies… CONTINUE READING
