Disease relevance of Pou3f1

  • Light microscopy of testes established that nodular interstitial cell hyperplasia was evident in 3 of 5 12-month-old rats and in 5 of 5 rats at 15, 18, 21, and 24 months of age [1].
  • In rats, the statistically significant increases in hepatocellular tumors and interstitial cell tumors of the testes were dose related [2].
  • Also, the rates of Leydig cell tumors of the testes (P less than 0.040) and pituitary adenomas (P less than 0.040) were statistically significant among males given the highest dose (0.6%) [3].
  • These results indicate that viable early torted testes must have their torsion corrected and be anchored in the scrotum, but if the testis is ischaemic and non-viable it should be removed to avoid damage to the contralateral testis [4].
  • Treatment of male Copenhagen F-1 rats bearing the Dunning 3327 prostate adenocarcinoma with 25 micrograms of D-Trp6-LH-RH per day for 42 days decreased the weights of both the ventral prostate and testes but had no effect on the weight of the anterior pituitary gland [5].
 

Psychiatry related information on Pou3f1

  • We examined locomotor activity on postnatal day 18 (PND 18), which is not influenced by perinatal androgens and juvenile play and testicular development (testes weight), which are dependent on perinatal androgen exposure, in rats whose dams consumed ethanol during pregnancy [6].
  • Males did not differ in age at the first appearance of spermatozoa in the testes but wild males were significantly older than Long--Evans and Sprague--Dawley domestic males at first copulation with a hormone-induced oestrous female [7].
  • Stereotyped behavior elicited by amphetamine in the rat: influences of the testes [8].
  • The time-response and magnitude of hCG-induced vascular changes are different in scrotal and abdominal testes [9].
  • PCS rats developed an increased urinary zinc excretion associated with weight loss, alopecia, lethargy and atrophy of the testes [10].

Regulatory relationships of Pou3f1

  • Recent studies further suggest that IL-6 has a role in down-regulating hormone production by endocrine organs and can negatively affect the steroidogenic capacity of both ovaries and testes [37].
  • In the present study, we have determined that Smad2 and Smad3 proteins are expressed in the postnatal testes of rats from 5 days to 60 days of age [38].
  • Western blot analysis revealed that TIP49a was abundantly expressed in testes and moderately in spleen, thymus, and lung [39].
  • The data obtained show that claudin-11 expression was inhibited in prepubertal rat testes exposed in utero to 2 and 10 mg/kg x d flutamide [40].
  • Similarly, after efferent duct ligation, the 0.9 kb SOD and PHGPX mRNA transcript levels also decreased compared to control testes (p < 0.05) [41].
 

Other interactions of Pou3f1

  • Northern blots indicate that Cx32 and Cx26 are typically coexpressed, messages for both having been identified in liver, kidney, intestine, lung, spleen, stomach, testes, and brain, but not heart and adult skeletal muscle [42].
  • Specific immunostaining of testes by antiserum against PHGPX appears as a fine granular brown pattern localized throughout the cytoplasm in more immature cells but is confined to the peripheral part of the cytoplasm, the nuclear membrane, and mitochondria in maturating spermatogenic cells [43].
  • Interaction of Fe-protoporphyrin IX and heme analogues with purified recombinant heme oxygenase-2, the constitutive isozyme of the brain and testes [44].
  • Cx33 and Cx31.1 genes exhibit a much more restricted pattern of expression; mRNAs are detected only in testes and skin, respectively [45].
  • Gene expression of FGFR-1 was developmentally regulated; expression was higher in prepubertal testes and decreased with sexual maturity [46].
 

Analytical, diagnostic and therapeutic context of Pou3f1

  • Northern blot analysis of total RNA and polyadenylated RNA isolated from adult rat testes showed that a proopiomelanocortin (POMC)-like messenger RNA molecule is present in these extracts [47].
  • Under these conditions, SSCs proliferated over 6 months, reconstituted long-term spermatogenesis after transplantation into recipient testes, and restored fertility to infertile recipients [48].
  • Most tissues of male rats, including blood, have very little if any ester (quantified by immunoassay as a nonpolar saponifiable metabolite), but fat and testes have sizable quantities, approximately 3 ng of testosterone equivalents per g of tissue [49].
  • In rats of the test group, a 75-mg/kg dose of EDS dissolved in dimethyl sulfoxide:water (1:3) was injected i.p. At intervals of 1, 2, 3, and 10 days after injection, two vehicle-injected control rats and three EDS-injected rats were sacrificed, and the testes were fixed by vascular perfusion [50].
  • In order to investigate the molecular basis of laminar patterning in the CNS, we have performed in situ hybridization studies of the POU homeodomain gene SCIP (also known as Tst-1 or Oct-6), which is expressed in proliferating Schwann cells in the PNS and O2A progenitor cells in the developing CNS [51].
