The modular mechanism of chromocenter formation in Drosophila

eLife, 2018
A central principle underlying the ubiquity and abundance of pericentromeric satellite DNA repeats in eukaryotes has remained poorly understood. In our previous study (Jagannathan et al., 2018), we proposed that the interchromosomal clustering of ...

Lateralization of retinal structure correlated with behavioral lateralization in the oval squid Sepioteuthis lessoniana [PDF]

Zoological Letters
Background Cephalopods, including Sepioteuthis lessoniana, preferentially orient either the left or right eye toward visual targets during various visually guided behaviors, as most of their visual field is monocular. Such visual lateralization is widely

HOMEODOMAIN-LIKE shapes chromatin architecture and rewires leaf epidermal patterns [PDF]

Nature Communications
During development, cells balance proliferation and differentiation to generate diverse cell types, yet how these transitions are fine-tuned remains unclear.

L-2-hydroxyglutarate regulates centromere and heterochromatin conformation in the male germline. [PDF]

PLoS Genetics
Germ cell differentiation in the male testis involves extensive phenotypic, transcriptional, and epigenetic modifications, which are essential for producing functional spermatozoa.

SMARCAD1 and TOPBP1 contribute to heterochromatin maintenance at the transition from the 2C-like to the pluripotent state [PDF]

eLife
Chromocenters are established after the 2-cell (2C) stage during mouse embryonic development, but the factors that mediate chromocenter formation remain largely unknown.

Defective Satellite DNA Clustering into Chromocenters Underlies Hybrid Incompatibility in Drosophila [PDF]

Molecular Biology and Evolution, 2021
Abstract Although rapid evolution of pericentromeric satellite DNA repeats is theorized to promote hybrid incompatibility (HI) (Yunis and Yasmineh 1971; Henikoff et al. 2001; Ferree and Barbash 2009; Sawamura 2012; Jagannathan and Yamashita 2017), how divergent repeats affect hybrid cells remains poorly understood.

Multi-tissue characterization of the constitutive heterochromatin proteome in Drosophila identifies a link between satellite DNA organization and transposon repression. [PDF]

PLoS Biology
Noncoding satellite DNA repeats are abundant at the pericentromeric heterochromatin of eukaryotic chromosomes. During interphase, sequence-specific DNA-binding proteins cluster these repeats from multiple chromosomes into nuclear foci known as ...
