[HTML][HTML] Meiotic sex chromosome inactivation and the XY body: a phase separation hypothesis

KG Alavattam, S Maezawa, PR Andreassen… - Cellular and Molecular …, 2022 - Springer
In mammalian male meiosis, the heterologous X and Y chromosomes remain unsynapsed
and, as a result, are subject to meiotic sex chromosome inactivation (MSCI). MSCI is required …

[PDF][PDF] SCML2 establishes the male germline epigenome through regulation of histone H2A ubiquitination

…, TJ Broering, AV Kartashov, KG Alavattam… - Developmental cell, 2015 - cell.com
Gametogenesis is dependent on the expression of germline-specific genes. However, it
remains unknown how the germline epigenome is distinctly established from that of somatic …

[PDF][PDF] Dynamic reorganization of open chromatin underlies diverse transcriptomes during spermatogenesis

S Maezawa, M Yukawa, KG Alavattam… - Nucleic acids …, 2018 - academic.oup.com
During spermatogenesis, germ cells undergo massive cellular reconstruction and dynamic
chromatin remodeling to facilitate highly diverse transcriptomes, which are required for the …

Attenuated chromatin compartmentalization in meiosis and its maturation in sperm development

KG Alavattam, S Maezawa, A Sakashita… - Nature structural & …, 2019 - nature.com
Germ cells manifest a unique gene expression program and regain totipotency in the zygote.
Here, we perform Hi-C analysis to examine 3D chromatin organization in male germ cells …

Endogenous retroviruses drive species-specific germline transcriptomes in mammals

…, S Maezawa, K Takahashi, KG Alavattam… - Nature structural & …, 2020 - nature.com
Gene regulation in the germline ensures the production of high-quality gametes, long-term
maintenance of the species and speciation. Male germline transcriptomes undergo dynamic …

BRCA1 establishes DNA damage signaling and pericentric heterochromatin of the X chromosome in male meiosis

TJ Broering, KG Alavattam, RI Sadreyev… - Journal of Cell …, 2014 - rupress.org
During meiosis, DNA damage response (DDR) proteins induce transcriptional silencing of
unsynapsed chromatin, including the constitutively unsynapsed XY chromosomes in males. …

Super-enhancer switching drives a burst in gene expression at the mitosis-to-meiosis transition

…, X Chen, K Takahashi, KG Alavattam… - Nature structural & …, 2020 - nature.com
Owing to bursts in the expression of thousands of germline-specific genes, the testis has the
most diverse and complex transcriptome of all organs. By analyzing the male germline of …

Polycomb protein SCML2 facilitates H3K27me3 to establish bivalent domains in the male germline

…, N Kubo, A Sakashita, KG Alavattam… - Proceedings of the …, 2018 - National Acad Sciences
Repressive H3K27me3 and active H3K4me2/3 together form bivalent chromatin domains,
molecular hallmarks of developmental potential. In the male germline, these domains are …

FANCB is essential in the male germline and regulates H3K9 methylation on the sex chromosomes during meiosis

Y Kato, KG Alavattam, HS Sin, AR Meetei… - Human Molecular …, 2015 - academic.oup.com
Fanconi anemia (FA) is a recessive X-linked and autosomal genetic disease associated
with bone marrow failure and increased cancer, as well as severe germline defects such as …

Polycomb directs timely activation of germline genes in spermatogenesis

…, M Yukawa, A Sakashita, KG Alavattam… - Genes & …, 2017 - genesdev.cshlp.org
During spermatogenesis, a large number of germline genes essential for male fertility are
coordinately activated. However, it remains unknown how timely activation of this group of …
