Different from meiosis, mitosis involves a single round of DNA replication followed by sister chromatids segregation, producing two daughter diploid cells [12]. MiMe is an artificial process switching meiosis into mitosis during sexual cell formation. MiMe can be triggered by the concurrent mutations ...
Mitosis refers to a type of cell division (cell cycle) through which the cell (parent cell) produces two identical daughter cells. Unlike meiosis, which is also a type of cell division, mitosis results in the production of two diploid daughter cells. The two daughter cells contain the same ...
diploid and tetraploid cells was not affected by the loss of BRD7 (Supplementary Fig. S4). Furthermore, no epididymal sperm was observed in the KO mice (Fig. 3E–G). Together, our results indicate that the loss of BRD7 led to male infertility and the absence of sperm in the epididymis...
Spermatogonia undergo several rounds of mitosis followed by meiosis of spermatocytes and spermiogenesis of spermatids in the seminiferous epithelium and subsequent release into the lumen1. During spermatogenesis, there are a series of changes associated with the differentiation of haploid round spermatids to...
As much as 75% of the genome may be expressed at some point during spermatogenesis, and 4% of the genome is uniquely transcribed specifically in meiotic and haploid cells (Schultz et al., 2003). Novel germ cell-specific transcription factors and altered forms of the general transcriptional ...
Of the changed biological processes, the top dynamic changes were related to cell cycle control, which indicates the importance of the transition of the cell cycle from meiosis to mitosis in the zygote stage. Furthermore, 31 pathways showed dynamic changes that were impaired by up-regulated genes...
