Rosiglitazone augments antioxidant response in the human trophoblast and prevents apoptosis.
In this study, we first examined whether rosiglitazone, an agonist of the peroxisome proliferator-activated receptor-γ (PPARγ), protects the human trophoblast from oxidative injury by regulating key antioxidant proteins, catalase (CAT) and the superoxide dismutases (SOD1 and SOD2). In first trimester placental explants, localization of CAT was limited to cytotrophoblasts, whereas SOD1 was expressed in both the cyto- and syncytiotrophoblasts. In first trimester placental explants, hypoxia decreased the expression of both SOD1 and SOD2, and increased apoptosis. Treatment with rosiglitazone dose-dependently upregulated anti...

Abstract
The chromatin associated transcription factor HMGA2 is a downstream target of let-7 miRNAs and binds to chromatin to regulate gene expression. Inhibition of let-7 miRNAs by RNA binding proteins LIN28A and LIN28B is necessary during early embryogenesis to ensure stable expression of HMGA2. In addition to LIN28, HMGA2 is regulated by a BRCA1/ZNF350/CtIP repressor complex. In normal tissues, the BRCA1/ZNF350/CtI...

Alpha7 Nicotinic Acetylcholine Receptor Regulates the Function and Viability of Enteroendocrine L Cells In Vitro.
Abstract
Enteroendocrine L cells secrete the incretin hormone glucagon-like peptide-1 (GLP-1) and they also express the α7 nicotinic acetylcholine receptor (α7nAChR) that might regulate GLP-1 secretion. Here, GTS-21, a selective α7nAChR agonist, was used to examine the impact of α7nAChR activation in L-cell lines, mouse intestinal primary cell cultures, and C57BL/6 mice. GTS-21 stimulated GLP-1 secretion in vitro and this effect was attenuated by an α7nAChR antagonist or by α7nAChR-specific siRNA. Under in vitro cell culture conditions of glucotoxicity, GTS-21 restored GLP-1 secretion and improved L-cell via...

Prox1 is essential for oligodendrocyte survival and regulates oligodendrocyte apoptosis via the regulation of NOXA.
Abstract
Demyelinating diseases, such as multiple sclerosis, are known to result from acute or chronic injury to the myelin sheath and inadequate remyelination. Its underlying molecular mechanisms, however, remain unclear. The transcription factor prospero homeobox 1 (Prox1) plays an essential role during embryonic development of the central nervous system and cell differentiation. Thus, we aimed to investigate the role of Prox1 in the survival and differentiation of oligodendrocytes. Cell viability was measured by MTT assay. Flow cytometry was conducted to analyze cell apoptosis. Ectopic-Prox1 and shProx1 were us...

Integrin β3 inhibits hypoxia-induced apoptosis in cardiomyocytes.
Abstract
Hypoxia-induced apoptosis plays an important role in cardiovascular diseases. Integrin β3 is one of the main integrin heterodimer receptors on the surface of cardiac myocytes. However, despite the important role that integrin β3 plays in the cardiovascular disease, its exact role in the hypoxia response remains unclear. Hence, in the present investigation we aimed to study the role of integrin β3 in hypoxia-induced apoptosis in H9C2 cells and primary rat myocardial cells. MTT assay, flow cytometry and TUNEL assay results showed that hypoxia inhibited cardiomyocyte proliferation and induced cardiomyocyt...

Long noncoding RNAs exchange during zygotic genome activation in goat.
Abstract
In mammals, their proper development during the early cleavage stages strongly relies on the gene products newly transcribed by zygotic genome activation (ZGA). Long noncoding RNAs (lncRNAs) have been characterized as key regulators of the ZGA process in mice and human. However, the ZGA stage has not yet been identified and epigenetic regulations of the ZGA process remain largely unknown in goats. Here, we show that ZGA occurred at the 8-cell stage in goats. During ZGA, tri-methylation of H3K9 was dynamically changed but maintained strong staining in development arrested embryos. Using single-cell RNA seq...

The regulatory role of SLP-2 and mechanism on CCBE1 gene expression in rectal carcinoma and adjacent lymphatic tube tissues.
CONCLUSIONS: SLP-2 is up-regulated in RC lymphatic tissues, and is positively correlated with the level of CCBE1, which provides the academic the basis for the development of medicine targeting SLP-2 in the anti-rectal carcinoma therapy.

Porcine Parvovirus infection impairs progesterone production in Luteal Cells through MAPKs, p53 and mitochondria-mediated Apoptosis.
Abstract
Porcine parvovirus (PPV) is a major virus leading to fetal death in swine. However, the effects of PPV infection on sows are poorly understood. The aim of this study was to investigate the effects of PPV on porcine steroidogenic luteal cells (SLCs) survival and functions and underlying mechanisms. In vivo experiment results showed artificial infection of PPV significantly reduced the concentration of serum progesterone and induced histopathological lesions and SLCs apoptosis in porcine corpora luteum. In vitro cultured primary porcine SLCs, PPV could infect and replicate in SLCs and induced SLCs apoptosis...

Reduced expression of mismatch repair genes MSH6/MSH2 directly promotes pituitary tumor growth via the ATR-Chk1 pathway.
Conclusion: Reduction of MSH6 and MSH2 expression at the mRNA and protein levels could be involved in direct PA proliferation by promoting cell-cycle progression or decreasing the rate of apoptosis through interference with the function of the ATR-Chk1 pathway.

Activation of Therapeutic Functionalities with Chimeric RNA/DNA Nanoparticles for Treatment of Cancer, Viruses and Other Diseases
A new strategy based on RNA/DNA hybrid nanoparticles, which can be generally used for triggering multiple functionalities inside diseased cells is presented. Individually, each of the hybrids is functionally inactive and functional representation can only be activated by the re-association of at least two cognate hybrids simultaneously present in the same cell. Overall, this novel approach allows (i) the triggered release of therapeutic siRNAs or miRNAs inside the diseased cells, (ii) activation of other split functionalities (e.g. FRET, different aptamers, rybozymes, split proteins) intracellularly, (iii) higher control o...

Design and delivery of therapeutic siRNAs: application to MERS-Coronavirus.
CONCLUSION: The efficacy of siRNA-based therapeutics has been used not only against many viral diseases but also against non-viral diseases, cancer, dominant genetic disorders, and autoimmune disease. This innovative technology has attracted researchers, academia and pharmaceuticals industries towards designing and development of highly effective and targeted disease therapy. By using this technology, an effective and potential siRNAs can be designed, delivered and their efficacy with toxic effects and immunogenic responses can be tested against MERS-CoV.

Adipocyte Expression of SLC19A1 Links DNA Hypermethylation to Adipose Tissue Inflammation and Insulin Resistance.
Conclusions: Reduced SLC19A1 expression in human adipocytes induces DNA hypermethylation resulting in increased expression of specific pro-inflammatory genes including CCL2. This constitutes an epigenetic mechanism that may link dysfunctional adipocytes to WAT inflammation and IR.
