Abstract Introduction/Objective Introduction: Cadherin-16 (CDH16), also termed kidney specific cadherin (ksp-cadherin), is a membrane-associated glycoprotein with role in the embryonal development of tubules and thyroid. Downregulation CDH16 RNA was found papillary carcinomas Methods/Case Report Methods: A set tissue microarrays containing 14,978 samples from 149 different tumor types subtypes ...
Glycoproteins on the plasma membrane of testicular and cauda epididymidal spermatozoa have been labeled with galactose oxidase/NaB [3H]4 and sodium metaperiodate/NaB[3H]4, followed by analysis on SDS polyacrylamide gels. The major glycoprotein labeling on testicular spermatozoa has a molecular weight 110,000 whereas on cauda epididymidal spermatozoa greater than 90% of the radio-label is incorp...
Phospholipids and sterols are known to have multiple functions in reproductive tissue of mammals. High concentrations of the cholesterol precursor desmosterol have been described in testis, epididymis, and spermatozoa of various species. These findings and the recent discovery of some cholesterol precursors as meiosis-activating sterols suggest important functions of cholesterol precursors in f...
The viscacha (Lagostomus maximus maximus) is a seasonal South American wild rodent. The adult males exhibit an annual reproductive cycle with periods of maximum and minimum gonadal activity. Four segments have been identified in the epididymis of this species: initial, caput, corpus, and cauda. The main objective of this work was to relate the seasonal morphological changes observed in the epid...
β-defensin peptides are a family of antimicrobial peptides present at mucosal surfaces, with the main site of expression under normal conditions in the male reproductive tract. Although they kill microbes in vitro and interact with immune cells, the precise role of these genes in vivo remains uncertain. We show here that homozygous deletion of a cluster of nine β-defensin genes (DefbΔ9) in the ...
Ethylene glycol monoethyl ether (EGEE) is known to have testicular toxicity. To elucidate whether EGEE has any effect on sperm motion, especially in the case of short time exposure, we conducted a series of in vivo experiments with rats, as well as an in vitro study with rat sperm. Sperm from cauda epididymides and spermaducts was analyzed for the change in motion with a Hamilton-Thorne Sperm a...
