Colon Cryptogenesis: Asymmetric Budding
The process of crypt formation and the roles of Wnt and cell-cell adhesion signaling in cryptogenesis are not well described; but are important to the understanding of both normal and cancer colon crypt biology. A quantitative 3D-microscopy and image analysis technique is used to study the frequency, morphology and molecular topography associated with crypt formation. Measurements along the col...
متن کاملAsymmetric nucleosomes flank promoters in the budding yeast genome.
Nucleosomes in active chromatin are dynamic, but whether they have distinct structural conformations is unknown. To identify nucleosomes with alternative structures genome-wide, we used H4S47C-anchored cleavage mapping, which revealed that 5% of budding yeast (Saccharomyces cerevisiae) nucleosome positions have asymmetric histone-DNA interactions. These asymmetric interactions are enriched at n...
متن کاملBudding transition of asymmetric two-component lipid domains.
We propose a model that accounts for the budding transition of asymmetric two-component lipid domains, where the two monolayers (leaflets) have different average compositions controlled by independent chemical potentials. Assuming a coupling between the local curvature and local lipid composition in each of the leaflets, we discuss the morphology and thermodynamic behavior of asymmetric lipid d...
متن کاملMicroRNA-200b is downregulated in colon cancer budding cells
BACKGROUND The microRNA-200 (miR-200) family acts as a major suppressor of epithelial-mesenchymal transition (EMT). Impaired miR-200 expression may lead to EMT initiation and eventually cancer dissemination. The presence of tumor budding cells (TBC) is associated with metastasis and poor prognosis, and molecular similarities to EMT indicate that these cells may reflect ongoing EMT. The aim of t...
متن کاملEffect of Budding Method, Rootstock Age and Cut below Budding Union on Budding Success in Persian Walnut
Budding is a good method of propagation in the Persian walnut (Juglans regia L.)., However, success of budding is low due to higher root pressure as well as the presence of phenolic compounds in the xylem sap. This study was conducted to compare various budding methods and cut below budding union on two and three-year-old Persian walnut under field conditions. The experiment was conducted based...
