From: 4-Hexylresorcinol and silk sericin increase the expression of vascular endothelial growth factor via different pathways

Figure 2

Expression of hypoxia inducible factor-1α (HIF-1α) and HIF-2α after treatment with (A) sericin or (B) 4-hexylresorcinol (4HR). Sericin increased expression of HIF-1α and HIF-2α. 4HR, at a dose equivalent to that of sericin, did not increase expression of HIF-1α or HIF-2α (cropped blot from different gels). (C) Relative expression of HIF-1α and HIF-2α to β-actin in sericin treated group. In case of 4HR group, expression levels of HIF-1α and HIF-2α was below the range of detection.
