Sex Chromatin and Nuclear Sexing in Birds
CYTOLOGIA, 1970 The present study deals with the incidence and distribution of sex chromatin body, drumstick and sessile bodies in two pairs, each of Gallus domesticus, Columba livia and Passer domesticus. Somatic tissues, i.e. liver, duodenum, skin and blood from both sexes were examined.

The multicopy gene Sly represses the sex chromosomes in the male mouse germline after meiosis.
PLoS Biology, 2009 Studies of mice with Y chromosome long arm deficiencies suggest that the male-specific region (MSYq) encodes information required for sperm differentiation and postmeiotic sex chromatin repression (PSCR).

Dual mechanism of chromatin remodeling in the common shrew sex trivalent (XY 1Y 2)
Comparative Cytogenetics, 2017 Here we focus on the XY1Y2 condition in male common shrew Sorex araneus Linnaeus, 1758, applying electron microscopy and immunocytochemistry for a comprehensive analysis of structure, synapsis and behaviour of the sex trivalent in pachytene spermatocytes.

Molecular Oncology, EarlyView.Small extracellular vesicles are a promising source of diagnostic molecules. We conducted a comprehensive study, including transcriptome profiling and RT‐qPCR validation on large cohorts of samples. Diagnostic panels enabling sensitive detection of colorectal cancer and precancerous lesions were established. Some molecules were differentially expressed

The Drosophila CLAMP protein associates with diverse proteins on chromatin. [PDF]
PLoS ONE, 2017 Gaining new insights into gene regulation involves an in-depth understanding of protein-protein interactions on chromatin. A powerful model for studying mechanisms of gene regulation is dosage compensation, a process that targets the X-chromosome to ...
