Figure Lengend Snippet: A) Immunoblotting analysis of MAPK signaling proteins after 24 hours dose-dependent treatment with PRED and DEX (0.1, 0.5, 1, 5, 10 µM). B) Immunoblotting analysis of MAPK signaling proteins after time-dependent treatment of 1 µM DEX (1, 2, 4, 8 hours). C) Box plots showing individual log 2 transformed label-free quantification of ADAM17 phosphorylation at Thr-735 and protein expression. D) Kinase activity analysis using RoKAI app after treatment of DEX. Bar color represents z-scored kinase activity (0 to 5). E-F) Box plots showing individual log 2 transformed label-free quantification of phosphorylation and protein expressions of MYH9 (E) and CXCR4 (F) after DEX treatment. G) Flow cytometry analysis of 2 and 24 hours DEX treatments in NLCs. Cells were stained with CD15, CD45, and CXCR4 (CD182). CD15 neg CD45 High cell populations are highlighted under live cell gate. Bar plot shows the number of CD15 neg CD45 High cells after DEX treatment and histogram represents CXCR4 expression of CD15 neg CD45 High cells. One-way ANOVA with Dunnette’s multiple comparisons test was used.
Article Snippet: MS quantifications were median normalized and statistical analysis was performed using one-way analysis of variance (ANOVA) followed by Tukey’s Honestly Significant Difference (HSD) post hoc test using R or one-way ANOVA with Dunnette’s multiple comparisons test using GraphPad Prism 10.
