In this study, the compounds having acrylophenone structure, 1-aryl-2-(N-methylpiperazinomethyl)-2-propen-1-one dihydrochlorides, were synthesized and their chemical structures were identified with (1)H NMR, (13)C NMR and HRMS spectra. The cytotoxicities of the compounds were tested towards Ca9-22 (human gingival carcinoma), HSC-2 (human oral squamous carcinoma), HSC-3 (human oral squamous carc...

In general, aging has been defined as a progressive decrease in the physiological capacity and the reduced ability to respond to environmental stresses lead to an increased susceptibility to disease 1) . It is well known that the severity of periodontal diseases is affected by the host s age 2) . In addition, recent studies have shown that the production of inflammatory mediators such as PGE2, ...

Connexins (C×s) are a family of transmembrane proteins that form hemichannels and gap junctions (GJs) on the cell membranes, and transfer small signaling molecules between the cytoplasm and extracellular space and between connecting cells, respectively. Among C×s, suppressing C×43 expression or function promotes skin wound closure and granulation tissue formation, and may alleviate scarring, bu...

PURPOSE Oral wound healing requires gingival fibroblasts to respond to local growth factors. Epigenetic silencing through DNA methylation can potentially decrease the responsiveness of gingival fibroblasts to local growth factors. In this study, our aim was to determine whether the inhibition of DNA methylation sensitized gingival fibroblasts to transforming growth factor-β1 (TGF-β1). METHODS...
