Figure Lengend Snippet: ( A ) Quantification of STAT1 mRNA levels via qPCR. ( B and C ) Representative Western blot images ( B ) and quantification ( C ) of the protein level of STAT1 at different timepoints after CHX treatment. ( D ) Western blot images showing the STAT1 protein levels in the CQ, MG132, and DMSO treatment groups. ( E and F ) Representative Western blot images ( E ) and quantification ( F ) of the protein level of Beclin1. ( G ) Representative immunofluorescence images showing SH2D5 and LC3 colocalization. Scale bar: 100 μm. Arrowheads: the cell that expresses LC3. ( H and I ) Representative Western blot images ( H ) and quantification ( I ) of LC3-II/LC3-I levels. ( J and K ) Representative Western blot images ( J ) and quantification ( K ) of STAT1 levels after RAPA administration. ( L and M ) Representative Western blot images ( L ) and quantification ( M ) of GluN1, GluN2A, and GluN2B levels after RAPA administration. The data are presented as mean ± SEM. Unpaired t test in A , F , I , K , and M ; 2-way ANOVA with Tukey’s multiple-comparison test in C . *** P < 0.001.
