Objective: Among herbal medicine, Allium sativum (garlic) has historically been used widely for the treatment of many disease such as hypertension, diabetes, tuberculosis, leprosy, constipation, parasitic infection, food poisoning, emmenagogue, abortion induction and many other disease. However, data about the particular effects of garlic such as activator of spermatogenesis has not been consid...
Yangjing capsule (YC), a traditional Chinese compound herbal preparation, has been proven as an effective drug to improve spermatogenesis in clinical practice. However, its pharmacological mechanisms were not fully clarified. This study was designed to investigate the protective effects of YC on spermatogenesis in the mouse model of spermatogenesis dysfunction induced by cyclophosphamide (CP). ...
BACKGROUND Spermatogenesis is the complex process by which diploid stem cells generate haploid germ cells in gamete production. Members of the Xlr (X-chromosome linked, lymphocyte regulated) superfamily play essential roles in spermatogenesis. The expression, localization and role in spermatogenesis of one such member, Xlr5c, has not been reported previously. METHODOLOGY/PRINCIPAL FINDINGS Xl...
The objective of this study was to further understand the genetic mechanisms of vitamin A deficiency (VAD) induced arrest of spermatogonial stem-cell differentiation. Vitamin A and its derivatives (the retinoids) participate in many physiological processes including vision, cellular differentiation and reproduction. VAD affects spermatogenesis, the subject of our present study. Spermatogenesis ...
BRD7 was originally identified as a novel bromodomain gene and a potential transcriptional factor. BRD7 was found to be extensively expressed in multiple mouse tissues but was highly expressed in the testis. Furthermore, BRD7 was located in germ cells during multiple stages of spermatogenesis, ranging from the pachytene to the round spermatid stage. Homozygous knockout of BRD7 (BRD7(-/-)) resul...
In the mammalian testis, the ubiquitin-proteasome system plays important roles in the process that promotes the formation of mature sperm. We recently identified zygote-specific proteasome assembly chaperone (ZPAC), which is specifically expressed in the mouse gonads and zygote. ZPAC mediates a unique proteasome assembly pathway in the zygote, but the expression profile and function of ZPAC in ...
Various histones, including testis-specific histones, exist during spermatogenesis and some of them have been reported to play a key role in chromatin remodeling. Mass spectrometry (MS)-based characterization has become the important step to understand histone structures. Although individual histones or partial histone variant groups have been characterized, the comprehensive analysis of histon...
BACKGROUND Epigenetic regulation by diverse classes of small RNAs is mediated by the highly conserved Argonaute/Piwi family of proteins. Although Argonautes are broadly expressed, the Piwi subfamily primarily functions in the germ line. Piwi proteins are associated with germline-specific ribonucleoprotein (RNP) granules in Drosophila, zebrafish, and mouse. Depending on the species and on the sp...
