Mechanisms of Oocyte Maturation and Related Epigenetic Regulation.
He M, Zhang T, Yang Y, Wang C. He M, et al. Front Cell Dev Biol. 2021 Mar 19;9:654028. doi: 10.3389/fcell.2021.654028. eCollection 2021. Front Cell Dev Biol. 2021. PMID: 33842483 Free PMC article. Review.
In female mammals, meiosis of oocytes starts before birth and sustains at the dictyate stage of meiotic prophase I before gonadotropins-induced ovulation happens. Once meiosis gets started, the oocytes undergo the leptotene, zygotene, and pachytene sta …

Hsu PJ, Zhu Y, Ma H, Guo Y, Shi X, Liu Y, Qi M, Lu Z, Shi H, Wang J, Cheng Y, Luo G, Dai Q, Liu M, Guo X, Sha J, Shen B, He C. Hsu PJ, et al. Cell Res. 2017 Sep;27(9):1115-1127. doi: 10.1038/cr.2017.99. Epub 2017 Aug 15. Cell Res. 2017. PMID: 28809393 Free PMC article.
The germ cells of Ythdc2 knockout mice do not develop past the zygotene stage and accordingly, Ythdc2 is upregulated in the testes as meiosis begins. ...

ZFP541 maintains the repression of pre-pachytene transcriptional programs and promotes male meiosis progression.
Xu J, Gao J, Liu J, Huang X, Zhang H, Ma A, Ye J, Zhang X, Li Y, Yang G, Yin H, Khan R, Li T, Fan S, Jiang X, Zhang Y, Jiang H, Ma H, Shi Q. Xu J, et al. Cell Rep. 2022 Mar 22;38(12):110540. doi: 10.1016/j.celrep.2022.110540. Cell Rep. 2022. PMID: 35320728 Free article.
The DSB machinery, which induces the programmed DNA double-strand breaks (DSBs) in the leptotene and zygotene stages during meiosis, is suppressed before the onset of the pachytene stage. ...

RNase H1 facilitates recombinase recruitment by degrading DNA-RNA hybrids during meiosis.
Liu C, Wang L, Li Y, Guo M, Hu J, Wang T, Li M, Yang Z, Lin R, Xu W, Chen Y, Luo M, Gao F, Chen JY, Sun Q, Liu H, Sun B, Li W. Liu C, et al. Nucleic Acids Res. 2023 Aug 11;51(14):7357-7375. doi: 10.1093/nar/gkad524. Nucleic Acids Res. 2023. PMID: 37378420 Free PMC article.
Notably, Rnaseh1 knockout results in incomplete DNA repair and meiotic prophase I arrest. These defects arise from the altered RAD51 and DMC1 recruitment in zygotene spermatocytes. ...

Time to match; when do homologous chromosomes become closer?
Solé M, Blanco J, Gil D, Valero O, Cárdenas B, Fonseka G, Anton E, Pascual Á, Frodsham R, Vidal F, Sarrate Z. Solé M, et al. Chromosoma. 2022 Dec;131(4):193-205. doi: 10.1007/s00412-022-00777-0. Epub 2022 Aug 12. Chromosoma. 2022. PMID: 35960388 Free PMC article.
The percentage of paired homologous chromosomes increases to 84.60% at mid-preleptotene-zygotene stage, reaching 100% at pachytene stage. Importantly, our results demonstrate a high percentage of homologous pairing observed before the onset of meiosis; this pairing does no …

Sorting out meiosis.
Stuart D. Stuart D. Cytometry A. 2014 Jun;85(6):474-6. doi: 10.1002/cyto.a.22468. Epub 2014 Mar 24. Cytometry A. 2014. PMID: 24664871 Free article. No abstract available.
A pathway for synapsis initiation during zygotene in Drosophila oocytes.
Tanneti NS, Landy K, Joyce EF, McKim KS. Tanneti NS, et al. Curr Biol. 2011 Nov 8;21(21):1852-7. doi: 10.1016/j.cub.2011.10.005. Epub 2011 Oct 27. Curr Biol. 2011. PMID: 22036181 Free article.
In "late zygotene" oocytes, SC initiates at many more sites that depend on the Kleisin-like protein C(2)M. Surprisingly, late zygotene synapsis initiation events are independent of the earlier mid-zygotene events, whereas both mid and late synapsis initiation …

3D genome remodeling and homologous pairing during meiotic prophase of mouse oogenesis and spermatogenesis.
He J, Yan A, Chen B, Huang J, Kee K. He J, et al. Dev Cell. 2023 Dec 18;58(24):3009-3027.e6. doi: 10.1016/j.devcel.2023.10.009. Epub 2023 Nov 13. Dev Cell. 2023. PMID: 37963468
We found that homologs adopted different sex-conserved pairing strategies prior to and after the leptotene-to-zygotene transition, changing from long interspersed nuclear element (LINE)-enriched compartments B to short interspersed nuclear element (SINE)-enriched compartme …

The Male Mouse Meiotic Cilium Emanates from the Mother Centriole at Zygotene Prior to Centrosome Duplication.
López-Jiménez P, Pérez-Martín S, Hidalgo I, García-Gonzalo FR, Page J, Gómez R. López-Jiménez P, et al. Cells. 2022 Dec 29;12(1):142. doi: 10.3390/cells12010142. Cells. 2022. PMID: 36611937 Free PMC article.
Here we describe the presence of cilia in male mouse meiotic cells. These solitary cilia formed transiently in 20% of zygotene spermatocytes and reached considerable lengths (up to 15-23 m). ...

Telomeric TERB1-TRF1 interaction is crucial for male meiosis.
Long J, Huang C, Chen Y, Zhang Y, Shi S, Wu L, Liu Y, Liu C, Wu J, Lei M. Long J, et al. Nat Struct Mol Biol. 2017 Dec;24(12):1073-1080. doi: 10.1038/nsmb.3496. Epub 2017 Oct 30. Nat Struct Mol Biol. 2017. PMID: 29083416 Free PMC article.
Notably, specific disruption of the TERB1-TRF1 interaction by a point mutation in the mouse Terb1 gene results in infertility only in males. We find that this mutation causes an arrest in the zygotene-early pachytene stage and mild telomere abnormalities of autosomes but u …
