a Representative images of LC3 staining by measuring fluorescence intensity of HDFs in different groups of cells infected with RFP-GFP-LC3 adenovirus for 24 h by fluorescence microscopy. b Quantitation of punctate structures per cell, based on the number of punctate structures in GFP-RFP-LC3-positive cells. c Cell viability in response to AZD1480. d Expression levels of JAK2, phospho-JAK2, STAT3, phospho-STAT3, AKT, and phospho-AKT measured by Western blot analysis in response to CSF2 depletion or CSF2 oversupply. e, h Relative protein expression levels of AKT and phospho-AKT in response to CSF2 depletion and CSF2 oversupply. f, i Relative protein expression levels of JAK2 and phospho-JAK2 in response to CSF2 depletion and CSF2 oversupply. g, j Relative protein expression levels of STAT3 and phospho-STAT3 in response to CSF2 depletion and CSF2 oversupply. Results presented as means ± SD of three independent experiments (n = 3). *Compared with the UVB-treated group, P < 0.05
