Figure Legend Snippet: TRPV4 activation led to increased phosphorylation of JAK2 and STAT3, thereby inducing NF-κB p65 translocation from the cytoplasm into the nucleus. A , C Immunoblotting analysis showing that GSK101 treatment increased the phosphorylation of STAT3 and JAK2, compared with the control group, but had no effect on the protein levels of JAK2 and STAT3 ( C ). B , D Bar charts summarizing mean expression levels of phosphorylated STAT3/STAT ( B ) and phosphorylated JAK2/JAK2 ( D ) under different conditions. n = 3 for all groups, * p

Figure Legend Snippet: Müller cells express functional TRPV4. A Immunofluorescence images show that cells with red autofluorescence are Müller cells. A1 Immunofluorescence images show cells with red autofluorescence in rat retinal vertical slices acquired from TdTomato transgenic mouse retina (Tomato). A2 Immunofluorescence images show glutamine synthetase (GS) protein staining (green) in the slices depicted in A1 . A3 Immunofluorescence images show DAPI (blue) staining in the slices depicted in A1 . A4 shows merged images. Scale bar: 50 µm. B Representative trace recorded from a Müller cell identified by spontaneous red fluorescence, showing that perfusion with GSK101 (10 μM) caused significant depolarization of Müller membrane potential. C Bar chart showing GSK101-induced depolarization of Müller cell membrane potential. n = 4. * p

Figure Legend Snippet: TRPV4 activation enhances the expression of GFAP. A Immunofluorescence images show GFAP protein expression profiles in rat retinal vertical slices acquired from sham-operated retinas (saline-injected; control) ( A1 ), 1 µM GSK101-injected retinas ( A2 ), and 10 µM GSK101-injected retinas ( A3 ). Retinas that received no GFAP antibody served as negative controls ( A4 ). Double immunofluorescence staining showing GFAP expression when the GFAP antibody was pre-adsorbed with its blocking peptide (BP) ( A5 ). Scale bar: 20 µm.
