...Elisavet Kouvidi; Haralambia Tsarouha; Sophia Zachaki; Christina Katsidi; Hara Tsimela; Amelia Pantou; Emmanuel Kanavakis; Ariadni Mavrou Introduction: X chromosome architecture and integrity are essential for normal ovarian function. Both numerical and structural X chromosome abnormalities play...

.... We report a male patient carrying a recombinant X chromosome derived from a maternally inherited intrachromosomal insertion. The patient exhibited developmental delay, intellectual disability, behavioral disorder, and dysmorphic facial features. To accurately identify the rearrangements...

...Ryoma Kudo; Ikuya Yoshida; Luisa Matiz Ceron; Shusei Mizushima; Yoko Kuroki; Takamichi Jogahara; Asato Kuroiwa X chromosome inactivation (XCI) is an essential mechanism for gene dosage compensation between male and female cells in mammals. The Okinawa spiny rat ( Tokudaia muenninki ) is a native...

...Anthony J. Tosi; Hirohisa Hirai A representative of Cercopithecus erythrotis was surveyed at a 9.3-kb region of the X chromosome. The data were compared against homologous sequences of closely related Cercopithecus monkeys including C. cephus , a species recently shown to have 2 polymorphic X...

Ben Khelifa H, Soyah N, Ben-Abdallah-Bouhjar I, Gritly R, Sanlaville D, et al: Xp22.3 interstitial deletion: a recognizable chromosomal abnormality...

...James A. Birchler Dosage compensation in Drosophila involves an approximately 2-fold increase in expression of the single X chromosome in males compared to the per gene expression in females with 2 X chromosomes. Two models have been considered for an explanation. One proposes that the male...

... estimates in L. migratoria as standard (5.89 pg). We first analyzed spermatids of 0B males and found a bimodal distribution of integrated optical densities (IODs), suggesting that one peak corresponded to +X and the other to –X spermatids. The difference between the 2 peaks corresponded to the X chromosome...

...K. Murakami; T. Ohhira; E. Oshiro; D. Qi; M. Oshimura; H. Kugoh Xist non-coding RNA (ncRNA) is essential for X chromosome inactivation (XCI). Some genes can escape from XCI, but how this occurs is unknown. We developed a modified RNA tagging and recovery of associated proteins (TRAP) method...
