Role of caspases in male infertility.
Apoptosis is characterized by a variety of changes resulting in the recognition and phagocytosis of apoptotic cells. Caspases (cysteinyl aspartate-specific proteinases) play a central role in the regulation of apoptosis in the human seminiferous epithelium. They are expressed as inactive proenzymes and participate in a cascade triggered in response to pro-apoptotic signals. To date, 14 caspases...
متن کاملA Review: Role of oxidative stress in male infertility
Recent studies have shown that reactive oxygen species (ROS) have a very important role in the intracellular signaling process in physiological conditions. On the other hand, during the recent decade it has been indicated that ROS play a role in various types of male infertility and it is due to the overproduction of ROS or decrease in the antioxidant defense system in the reproductive system a...
متن کاملThe role of Musashi protein in spermatogenesis and male infertility
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...
متن کاملInvestigating the Potential Role of piRNAs in Male Infertility
Infertility is a reproductive-related disorder and different factors account for its development. Male factors contribute to at least 20% of infertility. Despite the efforts performed in this field, the causes often remain idiopathic. Epigenetic factors such as small non-coding RNAs play important functions in male infertility. Also, P-element induced wimpy testis in drosophila-interacting RNAs...
متن کاملThe Role and Effect of Hspa2 in Male Infertility
The heat shock proteins (HSPs) are a group of homologous proteins encoded with a multigene family. They can be divided into five groups based on both size and function; including HSP27, HSP60, HSP70, HSP90 and HSP100. Expression of HSPs can be constitutive and can increased when cells undergo metabolic and/or heat stress. HSPA2/Hsp70-2 is a kind of HSP70 and constitutively expressed in testis. ...
