Platelet-derived growth factor-AA-mediated induction of mesencephalic astrocyte–derived neurotrophic factor involves miR-30a*/X-box binding protein 1 signaling in HAPI cells stimulated by lipopolysaccharide. A: Western blot analysis of PDGF-AA-induced MANF expression in activated HAPI cells. aP < 0.05, bP < 0.01 vs Control group; dP < 0.01 vs LPS group; eP < 0.05 vs 0.1 ng/mL and 1 ng/mL PDGF-AA groups; B: qRT-PCR analysis of miR-30a* expression in untreated or 10 ng/mL PDGF-AA-treated activated HAPI cells transfected with or without miR-mimics or miR-NC; C and D: Western blot (C) and qRT-PCR analysis (D) of ATF6 expression in untreated or 10 ng/mL PDGF-AA-treated activated HAPI cells transfected with or without miR-mimics or miR-NC; E and F: Western blot (E) and qRT-PCR analysis (F) of XBP1 expression in untreated or 10 ng/mL PDGF-AA-treated activated HAPI cells transfected with or without miR-mimics or miR-NC; G and H: Western blot (G) and qRT-PCR analysis (H) of MANF expression in untreated or 10 ng/mL PDGF-AA-treated activated HAPI cells transfected with or without miR-mimics or miR-NC. aP < 0.05, bP < 0.01 vs Control group; cP < 0.05, dP < 0.01 vs LPS group; eP < 0.05, fP < 0.01 vs LPS + PDGF-AA and LPS + PDGF-AA + miR-NC groups. The values are expressed as the mean ± SD (n = 6). MANF: Mesencephalic astrocyte–derived neurotrophic factor; PDGF-AA: Platelet-derived growth factor-AA; XBP1: X-box binding protein 1; ATF6: Activating transcription factor 6; GAPDH: Glyceraldehyde-3-phosphate dehydrogenase; LPS: Lipopolysaccharide; miR-NC: miR-30a*-negative control-transfected microglia; miR-mimics: miR-30a*-mimics-transfected microglia.
