Even though the discovery of the term 'epigenetics' was in the 1940s, it has recently become one of the most promising and expanding fields to unravel the gene expression pattern in several diseases. The most well studied example is cancer, but other diseases like metabolic disorders, autism, or inflammation-associated diseases such as lung injury, autoimmune disease, asthma, and type-2 diabetes display aberrant gene expression and epigenetic regulation during their occurrence. The change in the epigenetic pattern of a gene may also alter gene function because of a change in the DNA status...

BACKGROUND: New medical doctors enter their residency fields in July, a time in the hospital in which patient morbidity and mortality rates are perceived to be higher. It remains controversial whether a "July effect" exists in different areas of medicine and surgery, including in orthopedic surgery. The purpose of this study is to test for the July effect in patients undergoing primary total shoulder arthroplasty (TSA). METHODS: Patients who underwent primary TSA from 2005-2012 were identified using the American College of Surgeons National Surgical Quality Improvement Program database...

The development of predictive in vitro stem cell-derived hepatic models for toxicological drug screening is an increasingly important topic. Herein, umbilical cord tissue-derived mesenchymal stem cells (hnMSCs) underwent hepatic differentiation using an optimized three-step core protocol of 24 days that mimicked liver embryogenesis with further exposure to epigenetic markers, namely the histone deacetylase inhibitor trichostatin A (TSA), the cytidine analogue 5-azacytidine (5-AZA) and dimethyl sulfoxide (DMSO)...

BACKGROUND: There is growing interest in value-based health care in the United States. Statistical analysis of large databases can inform us of the factors associated with and the probability of adverse events and unplanned readmissions that diminish quality and add expense. For example, increased operating time and high blood urea nitrogen (BUN) are associated with adverse events, whereas patients on antihypertensive medications were more likely to have an unplanned readmission. Many surgeons rely on their knowledge and intuition when assessing the risk of a procedure...

Increasing evidences demonstrated that microRNAs (miRNAs) play critical roles in the human tumor development and progression. In our study, we found that miR-330-3p expression was downregulated in gastric cancer cell lines and tissues. Ectopic expression of miR-330-3p suppressed the gastric cancer cell proliferation, colony formation and migration. Overexpression of miR-330-3p promoted E-cadherin expression and inhibited the expression of N-cadherin, vimentin and snail. We identified Musashi-1 (MSI1) as a direct target gene of miR-330-3p in gastric cancer cell...

A Gram-stain-negative, non-spore-forming, non-motile, and aerobic coccobacilli shaped strain, designated BRTC-1T, was isolated from the gut of Omphisa fuscidentalis Hampson, which is a larva of a moth and was collected from Xishuangbanna Dai Autonomous Prefecture in China. The isolate was found to grow at NaCl concentrations of 0-5 % (w/v) (optimum: 0 %), 10-45 ℃ (optimum: 30-35 ℃) and pH 5.0-9.0 (optimum: 6.0) on TSA. Analysis of the 16S rRNA gene sequence indicated that the isolate belongs to the genus Acinetobacter and most closely related to Acinetobacter rudis LMG 26107T, Acinetobacter guillouiae LMG 988T and Acinetobacter bereziniae LMG 1003T with 96...

: Viral inclusion bodies (IBs) or replication factories are unique structures generated by viral proteins together with some cellular proteins as a platform for efficient viral replication, but little is known about the mechanism underlying IB formation and fusion. Our previous study demonstrated that the interaction between the nucleoprotein (N) and phosphoprotein (P) of human parainfluenza virus type 3 (HPIV3), an enveloped virus of great medical impact, can form IBs. In this study, we found that small IBs can fuse with each other to form large IBs that enhance viral replication...

Application of the enhanced recovery after surgery (ERAS) to the bariatric surgical procedures is at its early stages with little consolidated evidence. This meta-analysis evaluates present literature and indicates pathways for development of evidence-based standardized ERAS protocols for bariatric surgery. Comparative trials between ERAS and conventional bariatric surgery published till June 2016 were searched in the medical database. Comparisons were made for length of stay (LOS), readmission, complications (major/minor), and reoperation rates...

Trichostatin A (TSA), a histone deacetylase inhibitor, is used as an anti-carcinogenic and radiosensitizing agent in various cancers. However, the role and mechanism underlying its radiosensitization of tongue squamous cell carcinoma (TSCC) remains unclear. Thus, in this study we aimed to confirm the promotion of miR‑375 expression by TSA, and to investigate the effects of TSA and miR‑375 in the radiosensitivity of TSCC cells. The results showed that TSA had significant radiosensitizing effects on TSCC cells and miR‑375 overexpression had effects similar to TSA in sensitizing these cells to radiotherapy...

: Periodontal ligament cells have the potential to differentiate into bone forming osteoblasts and thus represent a good cellular candidate for bone regeneration. This study aimed to investigate the effect of inhibition of histone deacetylases, using the inhibitor Trichostatin A (TSA), on bone regeneration by human periodontal ligament cells (hPDLCs) in a mouse calvaria bone defect. METHODS: RUNX2 protein and its acetylation was analyzed by immunoprecipitation and western blotting...

Cell fate determination is tightly controlled by the expression of transcription factors and gene regulatory networks. PAX6 is a transcription factor containing a DNA-binding paired-box domain and homeobox domain that plays a key role in the development of the eye, brain, and pancreas. Here, we showed that histone deacetyltransferase 1 (HDAC1) is a novel binding partner of PAX6 in newborn mouse retinas. We also showed that HDAC1 specifically binds to the paired and transactivation domains of PAX6, and these physical interactions were required for effective repression of PAX6 transcriptional activity during retinal development...

The synthesis and photophysical properties of three tris(salicylideneaniline) (TSA) compounds containing 1,3,5-triarylbenzene, -tristyrylbenzene and -triarylethynylbenzene core units are reported. The TSA compounds undergo efficient excited state intramolecular proton transfer (ESIPT) in solution and in solid state due to the preformed C=N---H-O hydrogen bonded motifs of the structures. Steady state fluorescence emission spectra of the TSA molecules revealed dual bands in only DMSO, and large Stokes shifts in other polar aprotic and protic solvents...

Cloned mice derived from somatic or ES cells show placental overgrowth (placentomegaly) at term. We had previously analyzed cloned and normal mouse placentae by using two-dimensional gel electrophoresis and mass spectrometry to identify differential protein expression patterns. Cloned placentae showed upregulation of tissue inhibitor of metalloproteinase-2 (TIMP-2), which is involved in extracellular matrix degradation and tissue remodeling, and downregulation of pre-B cell colony enhancing factor 1 (PBEF), which inhibits apoptosis and induces spontaneous labor...

There have been extensive efforts to improve the outcome of glioblastoma, but the prognosis of this disease has not been significantly altered to date. Histone deacetylase inhibitors (HDACIs) have been evaluated as promising anti-cancer drugs and regulate cell growth, cell cycle arrest and apoptosis in glioblastoma. Here, we demonstrated the therapeutic efficacy of a novel pan-HDACI, 7-ureido-N-hydroxyheptanamide derivative (CKD5), compared with traditional pan-HDACIs, such as suberoylanilide hydroxamic acid (SAHA) and trichostatin A (TSA), in vitro and in vivo...
