A novel animal model of primary blast lung injury and its pathological changes in mice.

Background: Primary blast lung injury (PBLI) is a major cause of death in military conflict and terrorist attacks on civilian populations. However, the mechanisms of PBLI are not well understood, and a standardized animal model is urgently needed. This study aimed to establish an animal model of PBLI for laboratory study.

Design, synthesis, and biological evaluation of novel 3-(thiophen-2-ylthio)pyridine derivatives as potential multitarget anticancer agents.

A series of novel 3-(thiophen-2-ylthio)pyridine derivatives as insulin-like growth factor 1 receptor (IGF-1R) inhibitors was designed and synthesized. IGF-1R kinase inhibitory activities and cytotoxicities against HepG2 and WSU-DLCL2 cell lines were tested. For all of these compounds, potent cancer cell proliferation inhibitory activities were observed, but not through the inhibition of IGR-1R.

Transplantation of mesenchymal stem cells modulated Cx43 and Cx45 expression in rats with myocardial infarction.

At present, little is known about the influence of mesenchymal stem cell (MSC) transplantation on connexin43 (Cx43) and connexin45 (Cx45) remodeling in the ischemic heart. In this study, we investigated the effect of MSC transplantation on Cx43 and Cx45 remodeling in the ischemic heart. Wistar rats were subjected to left anterior descending artery ligation to induce myocardial infarction (MI) and then randomly allocated to receive an intramyocardial injection of PBS (MI group) or 5-azacytidine-induced MSCs (MSCs group).

The regulatory functions of piRNA/PIWI in spermatogenesis.

A class of 24-32 nt PIWI-binding small noncoding RNAs (sncRNAs) termed as PIWI-interacting RNAs (piRNAs) have been identified in animal germline. Recent studies suggest that piRNA/PIWI pathway plays a critical role in both silencing of transposons and posttranscriptional regulation of mRNAs in animal germline. A study from Dr.

Effects of histone deacetylase inhibitors on transcriptional regulation of the hsp70 gene in Drosophila.

Histone acetyltransferases/deacetylases contribute to the activation or inactivation of transcription by modifying the structure of chromatin. Here we examined the effects of histone deacetylase inhibitors (HDIs), trichostatin A, and sodium butyrate on hsp70 gene transcriptional regulation in Drosophila. The chromatin immunoprecipitation assays revealed that HDI treatments induced the hyperacetylation of histone H3 at the promoter and the transcribing regions of hsp70 gene, increased the accessibility of heat-shock factor to target heat-shock element, and promoted the RNA polymerase II-mediated transcription.

Function of c-Fos-like and c-Jun-like proteins on trichostatin A-induced G2/M arrest in Physarum polycephalum.

The homologs of transcription factors c-Fos and c-Jun have been detected in slime mold Physarum polycephalum during progression of the synchronous cell cycle. Here we demonstrated that c-Fos-like and c-Jun-like proteins participated in G2/M transition by the regulation of the level of Cyclin B1 protein in P. polycephalum.

Trichostatin A extends the lifespan of Drosophila melanogaster by elevating hsp22 expression.

The level of acetylation of histones in nucleosomes is related to the longevity of yeast and animals. However, the mechanisms by which acetylation and deacetylation affect longevity remain unclear. In present study, we investigated the influence of histone acetylation modification on the expression of hsp22 gene and the lifespan in Drosophila melanogaster using histone deacetylase (HDAC) inhibitor Trichostatin A (TSA).
