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.

Recent advances in malaria genomics and epigenomics [PDF]
, 2016 Malaria continues to impose a significant disease burden on low- and middle-income countries in the tropics. However, revolutionary progress over the last 3 years in nucleic acid sequencing, reverse genetics, and post-genome analyses has generated step ...

Advanced Science, EarlyView.The chimeric RNA ERCC1‐iASPP possesses dual coding and non‐coding functions, synergistically accelerating the process of cellular malignant transformation. Abstract Genetic variation at 19q13.3 critically modulates chemical carcinogen‐induced lung carcinogenesis, particularly in mediating the activity of benzo[a]pyrene (B[a]P), a major polycyclic ...

Plasmodium falciparum gametocytes display global chromatin remodelling during sexual differentiation
BMC Biology, 2023 Background The protozoan malaria parasite Plasmodium falciparum has a complex life cycle during which it needs to differentiate into multiple morphologically distinct life forms.

The genome of Romanomermis culicivorax:revealing fundamental changes in the core developmental genetic toolkit in Nematoda [PDF]
, 2013 Background: The genetics of development in the nematode Caenorhabditis elegans has been described in exquisite detail. The phylum Nematoda has two classes: Chromadorea (which includes C. elegans) and the Enoplea.

Advanced Science, EarlyView.This study suggests that prenatal aspirin exposure is associated with reduced ovarian reserve in offspring, associated with HDAC1‐linked epigenetic downregulation of Usp9x as a candidate mechanism. These preclinical findings provide new insights into fetal‐origin ovarian disorders and contribute to the evidence base concerning aspirin's gestational ...

Ultrastructural and immunocytochemical analysis of the XY body in rat and Guinea pig
European Journal of Histochemistry, 2009 The formation of the XY body involves the compaction of the extended chromatin to form a mesh of fibrogranular structures. During this process the ribonucleoprotein particles (RNP), which were associated with the chromatin filaments progressively ...

Chromatin modification by PSC occurs at one PSC per nucleosome and does not require the acidic patch of histone H2A. [PDF]
PLoS ONE, 2012 Chromatin architecture is regulated through both enzymatic and non-enzymatic activities. For example, the Polycomb Group (PcG) proteins maintain developmental gene silencing using an array of chromatin-based mechanisms.

Advanced Science, EarlyView.This study finds that CD8⁺ TSCM cells exhibit superior self‐renewal, differentiation, and antiviral activity. Transcriptome and epigenome analyses highlight MAPK cascade regulation in TSCM cells. In vivo, virus‐specific TSCM cells show enhanced persistence and tumor protection.
