Article Title: ATF3 aggravates kidney fibrosis via HDAC6-dependent epigenetic reprogramming
doi: 10.7150/ijbs.125062
Figure Lengend Snippet: The mechanism diagram of the study. Upregulated ATF3 in damaged tubular epithelial cells (TECs) promotes the progression of kidney fibrosis. In TECs, under homeostatic conditions, SMAD7 transcripts with histone 3 lysine 14 acetylation and histone opening. Under fibrotic conditions, upregulated ATF3 recruits HDAC6 to the SMAD7 promoter, eradicating histone 3 lysine 14 acetylation (H3K14ac) and diminishing SMAD7 transcription, thus activates TGF-β1/Smad3 signaling and aggravates kidney fibrosis.
Article Snippet: Mouse kidney epithelial cell line (TCMK-1), HEK 293T cells and rat renal interstitial fibroblasts (NRK-49F) cells were purchased from the American Type Culture Collection (Manassas, VA) and were cultured in DMEM (Sigma-Aldrich) containing 10% fetal bovine serum (FBS), at 37°C, 5% CO2, 95% air.
