Crossover distribution and high interference for both the X chromosome and an autosome during oogenesis and spermatogenesis in Caenorhabditis elegans.
Regulation of both the number and the location of crossovers during meiosis is important for normal chromosome segregation. We used sequence-tagged site polymorphisms to examine the distribution of all crossovers on the X chromosome during oogenesis and on one autosome during both oogenesis and spermatogenesis in Caenorhabditis elegans. The X chromosome has essentially one crossover during ooge...
متن کاملCaenorhabditis elegans homologue of the human azoospermia factor DAZ is required for oogenesis but not for spermatogenesis.
DAZ (Deleted in Azoospermia), the putative azoospermia factor gene in human, encodes a ribonucleoprotein-type RNA-binding protein required for spermatogenesis. A Drosophila homologue of DAZ, called boule, is also essential for spermatogenesis. A mouse homologue, Dazla, is implicated in both spermatogenesis and oogenesis. Here, we report the identification and characterization of daz-1, the sing...
متن کاملOccurrence and ultrastructural characterization of "nuage" during oogenesis and early spermatogenesis of Piaractus mesopotamicus Holmberg, 1887 (Teleostei).
We investigated the occurrence and ultrastructurally characterized electrondense nuclear material (nuage) released from the nucleus during oogenesis and early spermatogenesis of Piaractus mesopotamicus, a fish from Pantanal Matogrossense (Brazil) having a seasonal reproductive cycle. The female germ cells presented two instances of nuclear material extrusion: in the oogonia and in the oocyte in...
متن کاملMolecular characterization and expression profiles of cyclin B1, B2 and Cdc2 kinase during oogenesis and spermatogenesis in rainbow trout (Oncorhynchus mykiss).
The meiotic maturation of oocyte and spermatocyte in animals is controlled by the maturation promotion factor (MPF), a complex of Cdc2 and cyclin B proteins. To better understand the mechanism of oocyte and spermatocyte maturation in fish, the expression of cyclin B1 (CB1), B2 (CB2) and Cdc2 kinase during oogenesis and spermatogenesis in rainbow trout were examined at both the mRNA and protein ...
متن کاملRan-binding protein M is associated with human spermatogenesis and oogenesis
The aim of the present study was to explore the underlying mechanism and diagnostic potential of Ran‑binding protein M (RanBPM) in human spermatogenesis and oogenesis. RanBPM expression in human testis and ovaries was analysed using polymerase chain reaction (PCR) and western blotting, and immunofluorescence was performed on testis and ovary tissue sections during different developmental stages...
