AAV-mediated gene therapy restores natural fertility and improves physical function in the Lhcgr-deficient mouse model of Leydig cell failure.

Leydig cell failure (LCF) caused by gene mutations leads to testosterone deficiency, infertility and reduced physical function. Adeno-associated virus serotype 8 (AAV8)-mediated gene therapy shows potential in treating LCF in the Lhcgr-deficient (Lhcgr) mouse model. However, the gene-treated mice still cannot naturally sire offspring, indicating the modestly restored testosterone and spermatogenesis in AAV8-treated mice remain insufficient to support natural fertility.

Disruption of Cdyl gene impairs mouse lung epithelium differentiation and maturation.

CDYL is a chromodomain protein that has been identified as a transcriptional co-repressor that is primarily involved in the formation of repressor complexes which coordinate histone modifications to repress gene transcription. However, most functions and mechanisms of action of the CDYL protein are unknown. In this study, we show that Cdyl-/- mice died of respiratory distress immediately at birth because of distinct abnormalities in distal lung morphogenesis which was characterized by thickened septal and expiratory alveolus atelectasis.

Guanylate-binding protein 1 (GBP1) contributes to the immunity of human mesenchymal stromal cells against Toxoplasma gondii.

Mesenchymal stromal cells (MSCs) have recently been shown to play important roles in mammalian host defenses against intracellular pathogens, but the molecular mechanism still needs to be clarified. We confirmed that human MSCs (hMSCs) prestimulated with IFN-γ showed a significant and dose-dependent ability to inhibit the growth of two types of Toxoplasma gondii [type I RH strain with green fluorescent proteins (RH/GFP) or type II PLK strain with red fluorescent proteins (PLK/RED)]. However, in contrast to previous reports, the anti-T.

Nestin regulates neural stem cell migration via controlling the cell contractility.

Neural stem cells (NSCs) migration is essential for neurogenesis and neuroregeneration after brain injury. Nestin, a widely used marker of NSCs, is expressed abundantly in several cancers, where it may correlate with tumor migration and invasion. However, it is not yet known whether nestin participates in NSC migration.

Generation and neuronal differentiation of induced pluripotent stem cells in Cdyl-/- mice.

Chromodomain on Y-like (CDYL) is a chromodomain protein that has sequence homology to members of the enoyl CoA hydratase family. Although the chromodomain of CDYL has been implicated in chromatin remodeling during mammalian spermatogenesis, the function of the Cdyl gene remains unclear. Recently, induced pluripotent stem cells (iPS cells) have been derived from somatic cells by the forced expression of several transcription factors.

IFN-γ-primed human bone marrow mesenchymal stem cells induce tumor cell apoptosis in vitro via tumor necrosis factor-related apoptosis-inducing ligand.

Human mesenchymal stem cells hold promise as gene therapy vectors for delivery of various genes to solid tumors for either therapeutic or tumor-tracing purposes. However, whether Mesenchymal stem cells support or inhibit tumor growth remains unknown. Herein, we first observed that mesenchymal stem cells primed with IFN-γ selectively induced the death of tumor cell lines, but not normal cells.

[Expression status of diabetes-associated genes in middle and aged cynomolgus monkeys].

A total of 138 middle and aged cynomolgus monkeys (Macaca fascicularis) (above 10 years) were classified into three groups based on fasting plasma glucose (FPG) values, specifically low FPG, normal FPG, and high FPG group. Total cholesterol (TCHO), triglycerides (TG), high density lipoprotein cholesterol (HDL-C), and low density lipoprotein cholesterol (LDL-C) were detected in blood by automatic biochemical analyzer. The mRNA expressions of 37 diabetes-associated genes were analyzed with Real-time PCR in monocytes isolated from monkey peripheral blood.
