Chromatin accessibility dynamics in a model of human forebrain development

The chromatin accessibility complex: chromatin dynamics through nucleosome sliding.

development of feminist poetics in adrienne rich

اشعار ریچ، به عنوان اشعاری که همیشه در حال تغییر و دگرگونی هستند، تجسمی از رشد و دگرگونیِ انسان هستد. پایان نامه ی حاضر، با تمرکز بر روی مراحل سیر شعری ریچ از تغییری در دنیا به عکس هایی فوری از یک عروس، سپس به شیرجه به درون کشتی شکسته و در نهایت به صبری عجیب مرا تا اینجا آورده، به بررسی این مراحل در قالب نظر شوالتر در رابطه با سه مرحله ی پیشرفت ادبی زنان یعنی مرحله ی زنانه، زن گرا و زن محور می پ...

Chromatin accessibility dynamics reveal novel functional enhancers in C. elegans.

Chromatin accessibility, a crucial component of genome regulation, has primarily been studied in homogeneous and simple systems, such as isolated cell populations or early-development models. Whether chromatin accessibility can be assessed in complex, dynamic systems in vivo with high sensitivity remains largely unexplored. In this study, we use ATAC-seq to identify chromatin accessibility chan...

Local nucleosome dynamics facilitate chromatin accessibility in living mammalian cells.

Genome information, which is three-dimensionally organized within cells as chromatin, is searched and read by various proteins for diverse cell functions. Although how the protein factors find their targets remains unclear, the dynamic and flexible nature of chromatin is likely crucial. Using a combined approach of fluorescence correlation spectroscopy, single-nucleosome imaging, and Monte Carl...

Forebrain Development: Prosomere Model

The prosomeric model is a segmental structural model of the brain of vertebrates that explicitly holds that the brain is formed by an uninterrupted series of transverse subunits of the neural tube, generally called neuromeres. Among such subunits is a large rostral forebrain unit – the secondary prosencephalon – that encompasses hypothalamus, eyes, and telencephalon, followed by three caudal fo...
