Melanoma skin cancer develops from melanocytes, a cell type found in the skin that is involved in melanin production and that influences pigmentation. While skin cancers are the most common type of cancers, melanoma is less common, accounting for only about 1% of skin cancer cases. Melanoma is nonetheless a significant form of skin cancer due to its capability to metastasize to other tissues if not detected in early stages. Early-stage melanoma can be cured by resection, but fewer treatment options are available for patients with metastatic disease. Development of resistance to targeted and immunotherapies, as well as toxicity are major problems. Along with sun exposure, sporadic genetic mutations have been associated with melanomas. Immunotherapy treatments targeting these genes or pathways have been proven to have significant benefits in melanoma patients by improving general response and survival.
These NRAS-Mutant cell lines can be used to discover and address potential immunotherapies in NRAS-mutant human melanomas which make up an estimated 15-25% of human melanomas. These cell lines also enable in vivo testing of immunotherapies with a mouse model.
OSUMMER.12 NRAS mouse melanoma cell line was derived from a female TN mouse exposed to UVA and UVB radiation. OSUMMER.12 carries the specific NRAS mutation Q61R. WES revealed high SNV (Single Nucleotide Variants) and low CNA (Copy Number Alterations) burden, as well as the presence of UV signature mutations.

Source
OSUMMER.12 was derived from melanoma induced in TN (Tyr::CreER) mice exposed to UVA or UVB radiation on postnatal day 3.

Features and Benefits

The OSUMMER cell lines are responsive to immunotherapy treatments. These NRAS-Mutant cell lines can be used to discover and address potential immunotherapies in NRAS-mutant human melanomas which make up an estimated 15-25% of human melanomas. These cell lines also enable in vivo testing of immunotherapies with a mouse model. OSUMMER.12 carries the specific NRAS mutation Q61R and can form tumors in vivo without Matrigel injection.

Storage and Stability

OSUMMER.12 cells should be stored in liquid nitrogen until use. The cells can be cultured for at least 10 passages after initial thawing without significantly affecting the cell marker expression and functionality.
