The biological structure and function of the mammalian testis undergo important developmental changes during prepuberty and DNA methylation is dynamically regulated during testis development. In this study, we generated the first genome-wide DNA methylation profile of prepubertal porcine testis using methyl-DNA immunoprecipitation (MeDIP) combined with high-throughput sequencing (MeDIP-seq). Ov...
Background: Sodium arsenite and/ or vasectomy may cause variation in sex hormones which affect pathophysiology of reproductive organs. Objective: The aim was to investigate the morphological changes in structure of testis and hormonal imbalance in bilateral Vasectomised rats treated with sodium arsenite. Materials and Methods: Four groups of rats: bilateral vasectomy + sodium arsenite, bilatera...
In the rat testis, the vasopressin gene is transcribed into precursor RNAs that are processed into a number of mature transcripts. One of these transcripts has a structure identical to that of the hypothalamic RNA that encodes the vasopressin prepropeptide, but is present at such low levels that it can only be detected by the polymerase chain reaction. Other vasopressin-like RNAs are derived fr...
Gonadotropins are heterodimers consisting an alpha chain (Cgα) and a beta chain. Interestingly, presence of complicated LH-β transcripts in rat testis was accidently found; testicular LH-β transcripts were confined in seminiferous tubules to spermatids, and the translated products were localized in the elongated spermatids. We hypothesized that mouse testis has potential to produce the tissue s...
Quantitative microscopic structure of testis in adult Arabian rams, raised under closed grazing system in Khuzestan province of Iran, was studied in four seasons over a one year period. For this purpose, thirty adult rams were randomly selected and the live weight and scrotal circumference of rams were recorded. At the beginning of each season, among the study group, four rams were randomly sel...
Effects of Icariin on Histomorphometric Changes of Testis and Prostate Induced by Acrylamide in Mice
Background and Aims: This study aimed to observe the effect of Icariin on histomorphometric changes of testis and prostate induced by Acrylamide. Materials and Methods: Male mice were divided into four groups (n=8): A is the control group and does not get any treatment, B is the sham group and only received drinking water. C group received Acrylamide 10 mg/kg. D group received Acrylamide 15 mg...
