SNAIL1-mediated Downregulation of FOXA Proteins Facilitates the Inactivation of Transcriptional Enhancer Elements at Key Epithelial Genes in Colorectal Cancer Cells
Abstract: Phenotypic conversion of tumor cells through epithelial-mesenchymal transition (EMT) requires massive gene expression changes. How these are brought about is not clear. Here we examined the impact of the EMT master regulator SNAIL1 on the FOXA family of transcription factors which are distinguished by their particular competence to induce chromatin reorganization for the activation of transcriptional enhancer elements. We show that the expression of SNAIL1 and FOXA genes is anticorrelated in transcriptomes of colorectal tumors and cell lines. In cellular EMT models, ectopically expressed Snail1 directly represses FOXA1 and triggers downregulation of all FOXA family members, suggest...
Porokeratosis Plantaris, Palmaris Et Disseminata Caused by Con- Genital Pathogenic Variants in the MVD Gene and Loss of Heterozygosity in Affected Skin
Abstract: Porokeratoses are a heterogeneous group of keratinization disorders. For linear porokeratosis and disseminated superficial actinic porokeratosis, a heterozygous pathogenic germline variant in a mevalonate pathway gene and a postzygotic second hit mutation present in affected skin have been shown to be the pathogenetic mechanism for the development of the lesions. However, the molecular mechanism leading to development of porokeratosis plantaris, palmaris et disseminata is not known. This study analysed a cohort of 4 patients with linear porokeratosis and 3 patients with porokeratosis plantaris, palmaris et disseminata, and performed mutation analyses of DNA extracted from blood sam...

Visual Transduction And Non-Visual Light Perception
This book reveals not only how the eye evolved into an organ of vision, but also describes how molecular mechanisms of key molecules operate in the phototransduction cascade. In this groundbreaking text, experts also explain mechanisms for sensing radiation outside of the visible wavelengths. Comprehensive and penetrating, the book brings together the mechanisms of the visual transduction cascade and is an invaluable text for everyone conducting research in the visual system.
