Figure 3. Inflammatory cytokines, IL-1β and TNF-α, significantly increase levels of CRYAB in U373 cells and also its secretion of via exosomes.
(A) Exposure of U373 cells to inflammatory cytokines, IL-1β and TNF-α, for 24h showed a significant increase (B) in CRYAB levels compared to untreated cells. β-actin was used as loading control. Error bars, SD (*p<0.05). Similarly exosomes isolated from U373 cells exposed to inflammatory cytokines, IL-1β or TNF-α, were analyzed by western blot (C) for CRYAB levels. (D) Quantification of the western blots showed a significant increase in levels of secreted CRYAB in exosomes isolated from IL-1β and TNF-α treated cells. β-actin was used as loading control. Error bars, SD (p<0.0005).
