General description
The YUMM3.3 mouse melanoma cell line was derived from a 4-hydroxytamoxifen-induced melanoma tumor in a female C57/B1/6 mouse into which mutations from the Braf/Pten genetically-engineered mouse model had been introduced via backcrossing. The YUMM3.3 cell line harbors the Braf V600E mutation and is homozygous negative for Cdkn2.1?
The promise of immune-based therapies in cancer and increasingly successful application of these approaches have emphasized the necessity of immune-competent models to evaluate immunological responses to cancer cells. Immunocompetent genetically-engineered mouse models with distinct genetic drivers of melanoma are essential for identifying potential immunotherapies, but are limited by the need to maintain colonies of multiple genotypes necessary to generate mouse models with appropriate genetic backgrounds.YUMM3.3 cells are syngenic with the immunocompetent C57BL/6 mouse background and retain genetic markers of the Braf/Pten mouse model, characterized by activation of Braf and inactivation Cdkn2a. The YUMM3.3 cell line harbors wild-type Pten, allowing for comparative analysis for the parsing of distinct contributions of PI3K-Akt signaling in melanoma tumorigenesis and immune evasion. The YUMM3.3 mouse melanoma cell line represents a valuable tool for investigating the role of specific mutational profiles in melanomas and development of potential therapeutics.Mutation: BrafV600E/wt Cdkn2−/−.

Features and Benefits
The YUMM cell lines recapitulate genetic drivers found in many human melanomas. YUMM3.3 harbors the Braf V600E mutation and is homozygous negative for Cdkn2+.
Preparation Note
Store in liquid nitrogen. The cells can be cultured for at least 10 passages after initial thawing without significantly affecting the cell marker expression and functionality.
