RNA

Total RNA was prepared from cell line WM1232. WM1232 is a metastatic human melanoma cell line. This cell line features the specific V600E (Val600Glu) mutation at codon 600 in the BRAF gene. This mutation causes constitutively active kinase activity and activation of MEK and ERK signaling pathway. This cell line also expresses PTEN loss of function including hemizygous deletion and is wild type for N-RAS, c-KIT, and CDK4 genes. WM1232 cells produce xenograft tumors when injected into immunocompromised mice.

Total RNA was prepared from cell line WM1341D. WM1341D is a tumorigenic (VGP) primary melanoma cell line with competence for metastasis. These cells display epithelial square and triangular morphology in culture. This cell line features the specific V600R (Val600Arg) mutation at codon 600 in the BRAF gene. The V600R mutation results in an amino acid substitution at position 600 in BRAF, from a valine (V) to an arginine (R). This mutation occurs within the activation segment of the kinase domain. Mutations at V600 result in increased kinase activity and are transforming in vitro. WM1341D cells produce xenograft tumors when injected into immunocompromised mice.

Total RNA was prepared from cell line WM1361A. WM1361A is a tumorigenic (VGP) primary melanoma cell line with competence for metastasis. These cells display mesenchymal morphology in culture. This cell line contains a Q61R mutation at position 61 in the N-RAS gene. The Q61R is the most common NRAS mutation found in melanoma that is thought to occur due to UV and radiation exposure. This mutation leads to production of a constitutively active N-RAS protein that directs cells to grow and divide constantly. This cell line also expresses PTEN loss of function including hemizygous PTEN deletion and is wild type for BRAF, c-KIT, and CDK4. WM1361A cells produce xenograft tumors when injected into immunocompromised mice.

Total RNA was prepared from cell line WM1366. WM1366 is a tumorigenic (VGP) primary melanoma cell line with competence for metastasis. This cell line was established from a right forearm in a 79-year-old male with stage IV superficial spreading melanoma. WM1366 cells produce xenograft tumors when injected into immunocompromised mice. This cell line features a Q61L mutation at position 61 in the N-RAS gene. The Q61L mutation results in an amino acid substitution at position 61 in NRAS, from a glutamine (Q) to a leucine (L). The role of N-RAS mutations for selecting/prioritizing anticancer treatment, including cytotoxic chemotherapy and targeted agents, is unknown at this time. This cell line is wild type for BRAF, PTEN c-KIT, and CDK4.
