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.

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 ...
Of note, similar gene expression patterns associated with metastatic behaviour of breast cancer tumor cells have also been found in breast cancer of dog, the most common tumor of the female dog. [5] [6] Presented below are ways that gene expression profiling has been used to more precisely classify tumors into subgroups, often with clinical effect.
In several types of cancer, a loss of Numb expression has been demonstrated. This is well-established in breast cancer, where a loss of Numb correlates with a worse prognosis. [24] Numb loss has also been demonstrated in Non-small-cell lung carcinoma, salivary gland carcinoma, and chronic myelogenous leukemia. Restoration of Numb function, or ...
The overexpression of OLIG2 was later shown present in malignancies beyond glioma and leukemia, such as breast cancer, melanoma and non-small cell lung carcinoma cell lines. [23] It also has been shown that up-regulation of OLIG2 together with LMO1 and Notch1 helps to provide proliferation signals.
