Ean ?S.E. Significance (P <0.05) was determined using Student's t-test.
Ean ?S.E. Significance (P <0.05) was determined using Student's t-test. Statistical analysis was conducted using Sigma Stat 3.5 software.Additional filesAdditional file 1: HDAC1 and 2 are co-localized with cardiac fibroblast in the infarcted and non-infarcted myocardium in CHF. Coronal (LA) and axial (LV, RV) sections of sham and 6w CHF hearts were stained for HDAC1 (A-E) or HDAC2 (F-I) and Vimentin. Scale bars: 150 m. CHF, congestive heart failure; HDAC, Histone Deacetylase; LV, left ventricle; RV, right ventricle. Additional file 2: CD90+ cells express myofibroblast markers. (A) Flow cytometry analysis of CD90+ cells. CD90+ cells were fixed in 70 ethanol and double labeled with anti-CD90 antibody conjugated with FITC (BD Biosciences) and mouse anti-Vimentin or mouse anti-SMA antibodies following by labeling with anti-mouse IgG conjugated with PE-Cy5.5 (Life Technologies). For a negative control, cells were labeled with isotype IgG instead of primary antibody. Cell events were detected using FACS Calibur flow cytometer equipped with argon laser (BD Biosciences). Data were analyzed using CellQuest software (BD Biosciences). (B) CD90 cells isolated from both ventricles and atria express SMemb and Fn-EIIIA under culture conditions described in material and methods section. Fn-EIIIA, Fibronectin-EIIIA variant; SMemb, Smooth muscle embryonic myosin. Additional file 3: Mocetinostat treatment does not elevate apoptosis in CHF myocardium. Apoptotic cells were stained with CardioTACS in situ apoptosis detection kit (Trevigen) following manufacturer's instructions in both Mocetinostat treated and untreated CHF tissue sections. Briefly, tissue sections were fixed with 4 formaldehyde. Apoptosis assay was performed in situ by incorporating labeled nucleotides onto free 3 OH ends of DNA fragments using a terminal deoxynucleotide transferaseTotal RNA was extracted from CD90+ cells using PubMed ID:http://www.ncbi.nlm.nih.gov/pubmed/27107493 PureLinkTM RNA Mini Kit (Life Technologies) according to the manufacturer’s protocol. RNA was then quantified with the Quanti-iTTM RiboGreen?RNA Assay Kit, and assessed using BioTek Synergy HT Microplate Reader (excitation/emission 480 nm/520 nm). Total RNA (200 ng) was reverse transcribed with QuantiTect Reverse Transcription kit (Qiagen). Real-time RT-PCR was conducted using the Rower SYBR Green Master Mix (Applied Biosystems) on a StepOnePlus Real-time PCR System (Applied Biosystems). Specific primers were synthesized by Life Technologies (sequences are available upon request). CYP A was used as a reference gene. Data analysis was performed on PD325901 supplement StepOne software version 2.1 (Applied Biosystems) using the comparative Ct (Ct) quantitation method.Nural-Guvener et al. Fibrogenesis Tissue Repair 2014, 7:10 http://www.fibrogenesis.com/content/7/1/Page 13 ofenzyme. Streptavidin-horseradish peroxidase was used to detect biotinylated nucleotides incorporated. A dark blue precipitate was generated by reaction with TACS Blue label and visualized under light microscope. Arrows indicate positive cells for apoptosis.
