Notch 1 is a single ...
For example, Notch has been found to promote the expression of cyclin D3 and Cdk4/6 in human T-cells, thereby promoting the phosphorylation of Rb and facilitating the G1/S transition, implicating its role in cancer as several gain-of-function mutations in NOTCH1 have been identified in human acute T-cell lymphoblastic leukemias and lymphomas.
Once BMP expression was restored, [10] Msx1 expression was also restored, and regeneration proceeded.19 Similar studies have shown similar results in mouse digit tip regeneration. [9] The Notch1 pathway has demonstrated importance in the regeneration of frog tadpole tails. Notch1 is a gene in the Notch family of proteins.
Later studies in early Drosophila neurogenesis provided some of the first indications of Notch's roll in cell-cell signaling, as the nervous system in Notch mutants was developed by sacrificing hypodermal cells. [8] Starting in the 1980s researchers began to gain further insights into Notch function through genetic and molecular experiments.
Structure of a plant cell. Plant cells are the cells present in green plants, photosynthetic eukaryotes of the kingdom Plantae.Their distinctive features include primary cell walls containing cellulose, hemicelluloses and pectin, the presence of plastids with the capability to perform photosynthesis and store starch, a large vacuole that regulates turgor pressure, the absence of flagella or ...
JAG1 was first identified as a ligand that was able to activate notch receptors when the rat gene Jagged encoding a protein homolog was cloned in 1995. [5] [6] The structure of the JAG1 protein includes a small intracellular component, a transmembrane motif, proceeded by an extracellular region containing a cystine-rich region, 16 EGF-like repeats, a DSL domain, and finally a signal peptide ...
In plant immunology, the hypersensitive response (HR) is a mechanism used by plants to prevent the spread of infection by microbial pathogens.HR is characterized by the rapid death of cells in the local region surrounding an infection and it serves to restrict the growth and spread of pathogens to other parts of the plant.
Regulation of gene expression, or gene regulation, [1] includes a wide range of mechanisms that are used by cells to increase or decrease the production of specific gene products (protein or RNA). Sophisticated programs of gene expression are widely observed in biology, for example to trigger developmental pathways, respond to environmental ...
