Loss of Cx43 in Murine Sertoli Cells Leads to Altered Prepubertal Sertoli Cell Maturation and Impairment of the Mitosis-Meiosis Switch. [PDF]
Male factor infertility is a problem in today's society but many underlying causes are still unknown. The generation of a conditional Sertoli cell (SC)-specific connexin 43 (Cx43) knockout mouse line (SCCx43KO) has provided a translational model ...

Meiotic progression in arabidopsis is governed by complex regulatory interactions between SMG7, TDM1, and the meiosis I-specific cyclin TAM [PDF]
International audienceMeiosis is a modified cell division that produces four haploid nuclei from a single diploid cell in two rounds of chromosome segregation.

Histone modifications during tobacco male meiosis
The special and temporal distribution of several posttranslational histone modifications (H3K4me2, H3K4me3, H3K9me2, H3K27me2, H3K9ac, H3K14ac, H3K18ac, H3K27ac, H3S10ph, H3S28ph, H3T3ph, H3K4me1-H3T3ph, H3K4me3/H3T3ph H3T11ph, H2AT121ph, and H2A.XS139ph)

Development of human male meiosis in vitro [PDF]
Testes material from 16 men was used to study the development of human meiosis in vitro. The present report deals with the results from the analysis of the cells from the organ cultures of five of these men. H3-thymidine was added to the culture medium for 75 to 90 minutes.

Analysis of the transcriptional program governing meiosis and gametogenesis in yeast and mammals [PDF]
During meiosis a competent diploid cell replicates its DNA once and then undergoes two consecutive divisions followed by haploid gamete differentiation.

Male Meiosis: Y Keep It Silenced? [PDF]
What drives defective spermatocytes into apoptosis during mid-pachytene? A recent study identifies the first mid-pachytene 'killer' genes: two Y-linked transcription factors, the Zfy1/2 gene pair, must be silenced to avoid apoptosis.

Massive gene amplification on a recently formed Drosophila Y chromosome. [PDF]
Widespread loss of genes on the Y is considered a hallmark of sex chromosome differentiation. Here we show that the initial stages of Y evolution are driven by massive amplification of distinct classes of genes. The neo-Y chromosome of Drosophila miranda

In Drosophila males, there is no synaptonemal complex and recombination does not occur. Thus, Drosophila male meiosis is a good model system for the analysis of achiasmate chromosome segregation. In addition, due to their large size, the meiotic spindles of Drosophila males are an excellent system for mutational dissection of the mechanisms of spindle ...

The Drosophila Citrate Lyase Is Required for Cell Division during Spermatogenesis
The Drosophila melanogaster DmATPCL gene encodes for the human ATP Citrate Lyase (ACL) ortholog, a metabolic enzyme that from citrate generates glucose-derived Acetyl-CoA, which fuels central biochemical reactions such as the synthesis of fatty acids ...
