Abstract Spermiogenesis is a radical process of differentiation whereby sperm cells acquire a compact and specialized morphology to cope with the constraints of sexual reproduction while preserving their main cargo, an intact copy of the paternal gen

Epigenetic modifications are a key contributor to cell identity, and their propagation is crucial for proper development. Here the authors use a super-resolution microscopy approach to reveal how histone variants are faithfully transmitted during gen

O objetivo deste artigo é verificar a pertinência do conceito de Partidos Populistas Radicais de Direita (PPRD), desenvolvido por Cas Mudde, que forma parte do mainstream teórico que analisa os discursos das ultradireitas (extremistas e radicais)

Resumo Este estudo combina aportes historiográficos com entrevistas para analisar a situação do racismo na Argentina a partir do questionamento da concepção popular da homogeneidade racial do país. A Argentina entende-se, a partir do mito da ho

The formation of a diploid zygote is a highly complex cellular process that is entirely controlled by maternal gene products stored in the egg cytoplasm. This highly specialized transcriptional program is tightly controlled at the chromatin level in

International audience; Nucleosomes represent a challenge in regard to transcription. Histone eviction enables RNA polymerase II (RNAPII) progression through DNA, but compromises chromatin integrity. Here, we used the SNAP-tag system to distinguish n

The differentiation of post-meiotic spermatids in animals is characterized by a unique reorganization of their nuclear architecture and chromatin composition. In many species, the formation of sperm nuclei involves the massive replacement of nucleoso

Following fertilization of a mature oocyte, the formation of a diploid zygote involves a series of coordinated cellular events that ends with the first embryonic mitosis. In animals, this complex developmental transition is almost entirely controlled
