Background: Infertility problem affects young couples. One of the known causes of spermatogenic disorder is chemotherapy in patients with cancer. Since dividing cells are mainly affected by anticancer drugs, the aim of the present study is to investigate the preventive effect of GnRH on spermatogenic defect produced by anticancer drug. Materials and Methods: In the present study 30 adult female...
Background & Objective: Diabetes mellitus is a metabolic disease and is a multifactorial disorder characterized by chronic hyperglycemia resulting from impaired insulin secretion and insulin factional or both. In this study, the protective role of vitamin E and sodium selenite in preventing the harmful effects of insulin resistance (diabetes type 2) on spermatogenesis was studied. Materials &...
Introduction: Methamphetamine (MAMP) is a central nervous system stimulant that its consumption has increased among youths. Adolescence is considered as a critical period and the reproductive organs are developing is very sensitive so that the. In this study, the effects of methamphetamine on the development of the testes in immature male rats were evaluated. Methods: 40 immature male Wistar...
metronidazole and it’s derivatives are drugs that have both antiprotozoal and anti bacterial effect.the reproductive toxicity of metronidazole has been shown in some studies. to investigate the effect of metronidazole on spermatogenesis in adult male rats, this study was designed. eighteen wistar male rats (70-90days old) were randomly divided into three groups. animals in group i (control grou...
Increasing studies have shown that mature spermatozoa contain many transcripts including mRNAs and miRNAs. However, the expression profile of long non-coding RNAs (lncRNAs) in mammalian sperm has not been systematically investigated. Here, we used highly purified RNA to investigate lncRNA expression profiles in mouse mature sperm by stranded-specific RNA-seq. We identified 20,907 known and 4,08...
We have investigated the role of TGIF, a TALE-class homeodomain transcription factor, in Drosophila development. In vertebrates, TGIF has been implicated, by in vitro analysis, in several pathways, most notably as a repressor modulating the response to TGFbeta signalling. Human TGIF has been associated with the developmental disorder holoprosencephaly. Drosophila TGIF is represented by the prod...
Background: Inactivation of transcription occurs during two phases of spermatogenesis. First, in spermatocytes entering the primary meiosis and the second in round and elongating spermatids. These stages of inactivated transcription demand extensive regulation of translation. Therefore, presence of the control on gene expression during spermatogenesis seems essential. In the cases that post-tra...
