Reproductive system

Nowadays, there are many factors causing the decrease of male reproductive function such as diet, routine, chemical, ... But some of them have not been paid appropriate attention to, especially the use of paracetamol, which has a significant negative effect on the reproductive process. In this study, we will summarize the results of several studies on the harmful effects of prolonged high-dose use of paracetamol on sperm number, quality, portability and testicular morphology in experimental animals and humans.

Glutathione reductase (GR) recycles oxidized glutathione (GSSG) by converting it to the reduced form (GSH) using an NADPH as the electron source. The function of GR in the male genital tract of the rat was examined by meas-uring its enzymatic activity and examining the gene expression and localization of the protein.

Juvenile hormones (JHs) of insects are sesquiterpenoids that regulate a great diversity of processes in development and reproduction. As yet the molecular modes of action of JH are poorly understood. TheMethoprene-tolerant (Met) gene of Drosophila melanogasterhas been found to be responsible for resistance to a JH analogue (JHA) insecticide, methoprene. Previous studies onMethave implicated its involvement in JH signaling, although direct evidence is lacking.

During vitellogenesis, one of the most tightly regulated processes in ovipar-ous reproduction, vitellogenins are incorporated into the oocyte through vitellogenin receptor (VgR)-mediated endocytosis. In this paper, we report the cloning of the VgR cDNA from Blattella germanica, as well as the first functional analysis of VgR following an RNA interference (RNAi) approach.

The endocannabinoid system is a conserved system involved in the modula-tion of several physiologic processes, from the activity of the central ner-vous system to reproduction. Type 1 cannabinoid receptor (CNR1) cDNA was cloned from the brain and testis of the anuran amphibian, the frog Rana esculenta.

Sexual reproduction depends on the success of faithful chromosome trans-mission during meiosis to yield viable gametes. Central to meiosis is the process of recombination between paternal and maternal chromosomes, which boosts the genetic diversity of progeny and ensures normal homo-logous chromosome segregation.

Atrial natriuretic peptide, B-type natriuretic peptide and C-type natriuretic peptide constitute a family of three structurally related, but genetically dis-tinct, signaling molecules that regulate the cardiovascular, skeletal, nervous, reproductive and other systems by activating transmembrane guanylyl cyc-lases and elevating intracellular cGMP concentrations.
