Dopamine receptors and key elements of the neurotrophins (BDNF, CDNF) expression patterns during critical periods of ontogenesis in the brain structures of mice with autism-like behavior (BTBR) or its absence (С57BL/6J)

open access: yesВавиловский журнал генетики и селекции
Analysis of the mechanisms underlying autism spectrum disorder (ASD) is an urgent task due to the everincreasing prevalence of this condition. The study of critical periods of neuroontogenesis is of interest, since the manifestation of ASD is often ...

Whole transcriptome analysis of human erythropoietic cells during ontogenesis suggests a role of VEGFA gene as modulator of fetal hemoglobin and pharmacogenomic biomarker of treatment response to hydroxyurea in β-type hemoglobinopathy patients [PDF]

open access: yes, 2017
Background: Human erythropoiesis is characterized by distinct gene expression profiles at various developmental stages. Previous studies suggest that fetal-to-adult hemoglobin switch is regulated by a complex mechanism, in which many key players still ...
