Abstract:
We report the isolation and characterization of a chicken testis bcl-XL cDNA coding for a long bcl-x protein with a hydrophobic tail, and the expression of bcl-2 and bcl-x during chicken spermatogenesis. Bcl-2 is highly expressed in embryonic and immature testes enriched in spermatogonia and barely detectable in mature testes, where most of the cells are meiotic and postmeiotic. Bcl-x is expressed in both mature and immature testes, but in a lesser amount in mature testes. Differential expression of bcl-2 and bcl-x during spermatogenesis is consistent with the reported different susceptibility to apoptosis of spermatogonia, and meiotic and postmeiotic cells.

The Y Chromosome Determines Maleness
Evolution
Around 300 million years ago, the two sex chromosomes diverged from two identical autosomal chromosomes. Over time, the Y chromosome has lost most of its genes, shrinking in size. Today,...
Dosage Compensation
In addition to sexual development, the X chromosome has genes involved in autosomal functions such as brain development and the immune system. Therefore, males and females with distinct numbers of X chromosomes will have...

Spermatogenesis
The process of spermatogenesis can be divided into mitosis, meiosis, and spermiogenesis. During mitosis, the spermatogonia or stem cells divide to produce two identical daughter cells, type A and B spermatogonia. Type-A...
