Description
SK-LU-1 is a lung adenocarcinoma cell line that displays epithelial morphology and grows in adherent culture. This cell line expresses mutant K-Ras (G12D) and has homozygous deletions in the CDH6 and CDKN2A genes. These cells do not express the enzyme telomerase reverse transcriptase (hTERT) and consequently lack telomerase activity. This correlates with significantly reduced tumorigenicity in vitro and in vivo. These cells, however, display characteristics of alternative telomere lengthening (ALT) mechanisms (i.e., heterogeneity of telomere lengths and the presence of distinct nuclear structures called ALT-associated promyelocytic leukemia bodies). The SK-LU-1 cells do not form tumors when injected into immunocompromised mice.
Source
This cell line was established in 1969 from a 60-year-old Caucasian female with adenocarcinoma of the lung.
