The Potential Regulatory Mechanisms of miR-196a in Huntington's Disease through Bioinformatic Analyses.

High throughput screening is a powerful tool to identify the potential candidate molecules involved during disease progression. However, analysis of complicated data is one of the most challenging steps on the way to obtaining useful results from this approach. Previously, we showed that a specific miRNA, miR-196a, could ameliorate the pathological phenotypes of Huntington's disease (HD) in different models, and performed high throughput screening by using the striatum of transgenic mice.

miR-196a ameliorates phenotypes of Huntington disease in cell, transgenic mouse, and induced pluripotent stem cell models.

Huntington disease (HD) is a dominantly inherited neurodegenerative disorder characterized by dysregulation of various genes. Recently, microRNAs (miRNAs) have been reported to be involved in this dysregulation, suggesting that manipulation of appropriate miRNA regulation may have a therapeutic benefit. Here, we report the beneficial effects of miR-196a (miR196a) on HD in cell, transgenic mouse models, and human induced pluripotent stem cells derived from one individual with HD (HD-iPSCs).

CDC25 protein expression and interaction with DAZL in human corpus luteum.

Objective: To determine whether the human corpus luteum exhibits CDC25 protein expression and its expression pattern, and identify the interaction with DAZL (deleted in azoospermia-like) in human luteal cells.

Design: Experimental study.

Setting: Medical research laboratory in a university hospital.

In vivo and in vitro stimulatory effects of Cordyceps sinensis on testosterone production in mouse Leydig cells.

The in vivo and in vitro effects of Cordyceps sinensis (CS) and its extracted fractions on the secretion of testosterone in mice were studied. CS, F2 (water soluble protein), and F3 (poorly water soluble polysaccharide and protein) significantly stimulated in vitro testosterone production in purified mouse Leydig cells. However, F1 (water soluble polysaccharide) had no effect (p>0.

Regulatory mechanism of Cordyceps sinensis mycelium on mouse Leydig cell steroidogenesis.

We demonstrate the mechanism by which Cordyceps sinensis (CS) mycelium regulates Leydig cell steroidogenesis. Mouse Leydig cells were treated with forskolin, H89, phorbol 12-myristate 13-acetate, staurosporine, or steroidogenic enzyme precursors with or without 3 mg/ml CS; then testosterone production was determined. H89, but not phorbol 12-myristate 13-acetate or staurosporine, decreased CS-treated Leydig cell steroidogenesis.

Presence of DAZL transcript and protein in mature human spermatozoa.

Objective: To identify the DAZL transcript and protein location in human spermatozoa.

Design: In vitro experiment.

Setting: University-based reproductive genetics laboratory.
