Chromatin remodelers HELLS and UHRF1 mediate the epigenetic deregulation of genes that drive retinoblastoma tumor progression
The retinoblastoma (Rb) family of proteins are key regulators of cell cycle exit during development and their deregulation is associated with cancer. Rb is critical for normal retinal development and germline mutations lead to retinoblastoma making retinae an attractive system to study Rb family signaling. Rb coordinates proliferation and differentiation through the E2f family of transcription ...
متن کاملThe CHD3 remodeler PICKLE associates with genes enriched for trimethylation of histone H3 lysine 27.
In Arabidopsis (Arabidopsis thaliana), the ATP-dependent chromatin remodeler PICKLE (PKL) determines expression of genes associated with developmental identity. PKL promotes the epigenetic mark trimethylation of histone H3 lysine 27 (H3K27me3) that facilitates repression of tissue-specific genes in plants. It has previously been proposed that PKL acts indirectly to promote H3K27me3 by promoting...

متن کاملThe CKH2/PKL chromatin remodeling factor negatively regulates cytokinin responses in Arabidopsis calli.
Cytokinins promote cell division and chloroplast development in tissue culture. We previously isolated two mutants of Arabidopsis thaliana, ckh1 (cytokinin-hypersensitive 1) and ckh2, which produce rapidly growing green calli in response to lower levels of cytokinins than those found in the wild type. Here we report that the product of the CKH2 gene is PICKLE, a protein resembling the CHD3 clas...
متن کاملidentifying the strategies persian efl learners use in reading an expository text in english and examining its relation to reading-proficiency and motivation: a think-aloud study
هدف اصلی از این مطالعه بررسی نوع و میزان استراتژی هایی بود که دانشجویان فارسی زبان رشته ی زبان انگلیسی در حین خواندن یک متن انگلیسی به کار گرفتند. این مطالعه همچنین به بررسی تفاوت های استراتژی های مورد استفاده بین دارندگان سطح بالا و پایین درک مطلب پرداخت. نوع همبستگی بین استراتژی به کار گرفته و درک مطلب از یک سو و استراتژی به کار گرفته و انگیزه از سوی دیگر نیز در این تحقیق مورد آزمایش قرار گرف...
