Ubiquitin specific protease 26 (USP26), a deubiquitinating enzyme, is highly expressed early during murine spermatogenesis, in round spermatids, and at the blood-testis barrier. USP26 has also been recognized as a regulator of androgen receptor (AR) hormone-induced action involved in spermatogenesis and steroid production in in vitro studies. Prior mutation screening of USP26 demonstrated an as...
Introduction & Objective: Ciprofloxacin is a synthetic antibacterial agent belonging to the family of fluoroquinolones with a very broad spectrum against microbial pathogens, especially Gram-negative infectious diseases, that has been approved in more than 100 countries world-wide. The aim of this study was to see histopathological and cytotoxic effects of ciprofloxacin after inducement in rat ...
The relationship between the subcellular distribution of guanylate cyclase and tissue guanosine-3',5'-cyclic monophosphate (cGMP) levels was investigated in rat testes after surgically induced unilateral cryptorchidism. Placement of one of a testis pair in the abdominal cavity results in loss of testicular weight and function in the abdominal testis whereas the remaining scrotal testis appears ...
Abstract We measured gonad size (diameter and circumference) by ultrasound used it as a metric to assign stage of maturity in Burbot Lota lota from Lake Roosevelt, Washington. collected paired tissue measurements monthly November 2017 March 2018 processed for histological analysis confirm maturity. diameter circumference ultrasound. also excised (i.e., true diameter) digital calipers measuring ...
background: vitamin e is an effective antioxidant, protecting cells against oxidative stress. objective: in this investigation the protective effect of vitamin e on the testis during development and spermatogenesis in rats exposed to sodium arsenite was evaluated. materials and methods: pregnant wistar rats were divided into 4 groups (n=8) control, sodium arsenite (8 mg/kg/day), sodium arsenite...
The testis has been identified as the organ in which a large number of tissue-enriched genes are present. However, a large portion of transcripts related to each stage or cell type in the testis still remains unknown. In this study, databases combined with confirmatory measurements were used to investigate testis-enriched genes, localization in the testis, developmental regulation, gene express...
Sex reversal can occur in XY humans with only a single functional WT1 or SF1 allele or a duplication of the chromosome region containing WNT4. In contrast, XY mice with only a single functional Wt1, Sf1, or Wnt4 allele, or mice that over-express Wnt4 from a transgene, reportedly are not sex-reversed. Because genetic background plays a critical role in testis differentiation, particularly in C57...
Biotransformation of steroid hormones by a spontaneous interstitial cell tumor originating from a BALB/cJ mouse has been studied in vitro. Tumor tissue grown in a female host converted estrone predominantly to estradiol-17~. The same tissue transformed estradiol-17/~ to estrone to a considerably lesser extent. Incubation of the tumor tissue with androstenedione yielded testosterone as the princ...
