X-chromosome methylation in manifesting and healthy carriers of dystrophinopathies: concordance of activation ratios among first degree female relatives and skewed inactivation as cause of the affected phenotypes
(1995)
The X-chromosome activity states of 11 manifesting carriers of dystrophinopathies, all with normal karyotypes, were estimated by restriction fragment length polymorphism (RFLP)-methylation analysis with the probes M27I3 ...

MARSUPIAL SEX CHROMOSOME BEHAVIOUR DURING MALE MEIOSIS
(SPRINGER, 2010)
The absence of homology between sex chromosomes in marsupials strongly influences their behaviour during male meiosis. The highly differentiated X and Y chromosomes perform a precise and specific meiotic program that ...
Revisiting the X-Chromosome Inactivation and Its Impact on Female Longevity
X-chromosome inactivation is the genetic mechanism by which X-linked gene expression is equalized between the male and female genders of all placental mammal species. Given that the probability of mutant X-linked allele ...
Heteropicnotic chromatin and nucleolar activity in meiosis and spermiogenesis of Limnogonus aduncus (Heteroptera, Gerridae): a stained nucleolar organizing region that can serve as a model for studying chromosome behavior.
(2008-12-01)
Males of Limnogonus aduncus were found to have the sex chromosome system X0 and chromosome number 2n = 23 (22A + X0). Testis cells were stained with lacto-acetic orcein and silver nitrate so that changes in the morphology ...

Allele-specific expression analysis reveals conserved and unique features of preimplantation development in equine ICSI embryos
(Society for the Study of Reproduction, 2021-09)
Embryonic genome activation and dosage compensation are major genetic events in early development. Combined analysis of single embryo RNA-seq data and parental genome sequencing was used to evaluate parental contributions ...
Investigação da propagação da inativação do cromossomo x para sequências autossômicas em indivíduos com translocações x-autossomo não equilibradas
(Universidade Federal de São Paulo (UNIFESP), 2021)
Background: X-chromosome inactivation (XCI) is an epigenetic mechanism that aims at dosage compensation between males (XY) and females (XX) regarding the expression of X-linked genes. Even though the choice of which X ...
