Description

General description

The YUMM2.1 mouse melanoma cell line was derived from a 4-hydroxytamoxifen-induced melanoma tumor in a male C57BL/6 mouse into which mutations from the Braf/Pten genetically-engineered mouse model had been introduced via backcrossing. The YUMM2.1 cell line harbors the Braf V600E mutation and is homozygous negative for wild-type Pten, heterozygous for Cdkn2, and characterized by expression of stable beta-catenin via partial Cre/lox recombination.

Application

• Each vial contains > 1X10⁶ viable cells.
• Cells are tested negative for infectious diseases by a Mouse Essential CLEAR panel by Charles River Animal Diagnostic Services.
• Cells are verified to be of mouse origin and negative for inter-species contamination from rat, chinese hamster, Golden Syrian hamster, human and non-human primate (NHP) as assessed by a Contamination CLEAR panel by Charles River Animal Diagnostic Services.
• Cells are negative for mycoplasma contamination.

Features and Benefits

The YUMM cell lines recapitulate genetic drivers found in many human melanomas. YUMM2 harbors the Braf V600E mutation and is homozygous negative for wt Pten and is Cdkn2+.

Target description

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 backgroundsYUMM2.1 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 of Pten and Cdkn2a. The YUMM2.1 cell line harbors a stabilized beta-catenin allele from excision of exon 3, a mutation that accelerates Braf/Pten-driven melanoma tumorigenesis, enhances metastasis, and controls tumor differentiation. Exon 3 excision is analogous to human beta-catenin stabilizing mutations found in human melanomas.Mutation: BrafV600E/wt Pten−/− Cdkn2+/−Bcat loxex3/wt. Partial Bcat STA/wt recombination​.

Storage and Stability

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.
