Figure Legend Snippet: A, VS-6063 reduced levels of phosphorylated HDAC4 and HDAC5. n=4 biological replicates in each group. B, Silencing FAK also reduced the phosphorylation of HDAC4 and HDAC5 in HASMCs grown in common medium or osteogenic medium. n=4 biological replicates in each group. C, FAK inhibition using VS6063 decreased cytosolic localization and increased nuclear localization of HDAC4 and HDAC5 in osteogenic media as shown by immunofluorescence images (60x). 30 cells in each group were used for analysis.
Techniques Used: Inhibition, Phospho-proteomics, Immunofluorescence
Figure Legend Snippet: Leptomycin B (LEP) inhibited nuclear export of HDAC4 and HDAC5 in A , normal media and B , in osteogenic media as shown by immunofluorescence. 12–46 cells in each group were used for analysis. C, Leptomycin B reduced phosphorylated HDAC4 and HDAC5 and inhibited the expression of RUNX2 and ALPL in osteogenic media. n=4 biological replicates in each group.
Techniques Used: Inhibition, Immunofluorescence, Expressing
Figure Legend Snippet: A , Increased expression of HDAC4/5 was achieved by adenovirus transduction (Ad.HDAC4 or Ad.HDAC5). B, Ad.HDAC4 or Ad.HDAC5 resulted in enhanced calcification that was inhibited with the treatment of leptomycin B (5nM) n=3 biological replicates in each group (with 2 representative replicates shown). Quantitative calcium assay in cells treated with C, Ad.HDAC4 and D , Ad.HDAC5 in the presence or absence of leptomycin demonstrated reduced calcification with leptomycin treatment. n=3 biological replicates in each group. E and F, Cytosolic and nuclear localization of HDAC4 and HDAC5 in AdHDAC4 and AdHDAC5 treated cells in the presence and absence of leptomycin (a nuclear export inhibitor, 10 nM for 3 hours) in osteogenic media. 12–13 cells in each group were used for analysis.
Techniques Used: Over Expression, Expressing, Transduction, Calcium Assay
Figure Legend Snippet: A, Treatment of HASMCs with siHDAC4 resulted in >70% and >65% knockdown of HDAC4 mRNA level in common or osteogenic medium, respectively. n=6 biological replicates in each group. B, Protein levels of RUNX2 and ALPL were increased with osteogenic medium. However, siHDAC4 decreased the levels of RUNX2 and ALPL induced by osteogenic medium. n=4 biological replicates in each group. C, Treatment of HASMCs with siHDAC5 resulted in >55% and >50% knockdown of HDAC5 mRNA level in normal or osteogenic medium, respectively, and decreased HDAC5 protein levels in siHDAC5-treated cells. n=6 biological replicates in each mRNA group. D, siHDAC5 decreased the protein levels of RUNX2 and ALPL induced by osteogenic medium. n=4 biological replicates in each group. E, Treatment with siHDAC4, siHDAC5, or the combination inhibited calcification of HASMCs grown in osteogenic medium for 14 days, as evidenced by Alizarin Red staining. n=3 biological replicates in each group (with 2 representative replicates shown). F, Treatment of HASMCs with LMK-235 (a pharmacologic inhibitor of HDAC4 and HDAC5) inhibited calcification induced by osteogenic medium in a dose-dependent manner. n=2 biological replicates in each group G, LMK-235 reduced the migration of VSMCs induced by osteogenic medium. The experiments in figure 1H and 7G were performed at the same time. n=6 biological replicates in each group.
Techniques Used: Inhibition, Knockdown, Staining, Migration
Figure Legend Snippet: A and B, Increased HDAC4 or HDAC5 expression by adenovirus resulted in augmented calcification of HASMCs that was inhibited by treatment with the FAK inhibitor VS-6063 (1μM). n=3 biological replicates in each group (with 2 representative replicates shown). C and D, Reduction of FAK expression with siFAK significantly attenuated the calcification of HASMCs induced by Ad.HDAC4 or Ad.HDAC5 in osteogenic medium or induced by osteogenic medium alone. n=3 biological replicates in each group (with 2 representative replicates shown). E and F, Osteogenic medium induced calcification of mouse aortas and human carotid arteries after culturing for 21 days. However, the calcification induced by osteogenic medium was inhibited by treatment with VS-6063 (2μM or 4μM). n=4 biological replicates in each group.
Techniques Used: Inhibition, Over Expression, Cell Culture, Expressing
Figure Legend Snippet: Localization of PTK2 , HDAC5 , and HDAC4 gene expression in modulated SMC subtypes using an integrated human atherosclerosis reference. Uniform Manifold Approximation and Projection (UMAP) embeddings from an integrated human atherosclerosis single-cell RNA-seq reference dataset (see Methods ), highlighting ( A ) PTK2 , ( B ) HDAC5 , and ( C ) HDAC4 normalized gene expression. Individual sequencing libraries across four studies were harmonized after QC and batch correction with reciprocal PCA (rPCA). A broad SMC cluster was annotated using transfer learning with cell labels from the Tabula Sapiens vasculature subset. SMC subtypes were further annotated by extracting gene modules from a scRNA meta-analysis of murine SMCs (contractile SMC, transitional SMC, fibromyocyte, and fibrochondrocyte) and calculating their enrichment in cells within the main SMC cluster. PTK2 and HDAC5 expression were enriched in transitional SMCs and fibromyocytes.
Techniques Used: Gene Expression, RNA Sequencing, Sequencing, Expressing
