Acute 4‐PBA treatment reduces UPR activation in short‐term primary osteoblast culture. (A–K) Quantification of Western blots probed for UPR receptors and downstream transducers in primary calvarial osteoblasts cultured and treated with 5nM 4‐PBA for 7 days. n = 7 per treatment group. Quantifications are displayed with median and interquartile range. Two‐way ANOVAs were performed, *p < 0.05 was considered statistically significant. (L) Representative Western blots of relative protein levels.
