Frequent BRG1/SMARCA4-inactivating mutations in human lung cancer cell lines
Open accessAbstract
Components of the SWI/SNF chromatin-remodeling complex, such as INI1, are inactivated in human cancer and, thus, act as tumor suppressors. Here we screened for mutations the entire coding sequence of BRG1 (SMARCA4), which encodes the ATPase of the complex, in 59 lung cancer cell lines of the most common histopathological types. Mutations were detected in 24% of the cancer cell lines, many of them in cells commonly used for lung cancer research. All mutations were homozygous and most predicted truncated proteins. The alterations were significantly more frequent in the non-small-cell lung cancer (NSCLC) type (13/37, 35%) as compared to the small-cell lung cancer (SCLC) type (1/19, 5%) (P<0.05; Fisher's Exact test) and BRG1 was the fourth most frequently altered gene in NSCLC cell lines. BRG1 mutations coexisted with mutations/deletions at KRAS, LKB1, NRAS, P16, and P53. However, alterations at BRG1 always occurred in the absence of MYC amplification, suggesting a common role in lung cancer development. In conclusion, our data strongly support that BRG1 is a bona fide tumor suppressor and a major factor in lung tumorigenesis.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
