Occurrence of ras mutations in human lung cancer. Minireview
1Laboratory of Molecular Biology, University Hospital, Bulovka, Czech Republic.
Abstract:
Members of ras family of oncogenes, when activated by a point mutation, have been implicated in many types of human cancers. In several types of human solid tumors, point mutations of the K-ras gene are relatively frequent. Among lung cancers, a subset of non-small cell lung carcinomas, mostly adenocarcinomas, contains activated K-ras. The examination of K-ras mutations in samples obtained for diagnostic reasons, such as bronchial biopsies or bronchoalveolar lavage fluid, may be used as a supplement in the early diagnosis of lung adenocarcinoma.
Insights
Ras family oncogenes, including K-ras, are linked to human cancers. Detecting K-ras mutations in diagnostic samples may aid early lung adenocarcinoma diagnosis.
Area of Science:
- Oncology
- Molecular Biology
- Genetics
Background:
- Ras family oncogenes are frequently activated by point mutations in human cancers.
- K-ras gene point mutations are common in various human solid tumors.
- Activated K-ras mutations are found in a subset of non-small cell lung carcinomas, particularly adenocarcinomas.
Purpose of the Study:
- To investigate the role of K-ras mutations in lung cancer.
- To assess the utility of detecting K-ras mutations for early lung adenocarcinoma diagnosis.
Main Methods:
- Analysis of K-ras mutations in clinical samples.
- Utilizing diagnostic samples such as bronchial biopsies and bronchoalveolar lavage fluid.
Main Results:
- K-ras mutations are present in a subset of lung adenocarcinomas.
- Examination of K-ras mutations can be performed on readily available diagnostic samples.
Conclusions:
- K-ras mutation analysis can supplement the early diagnosis of lung adenocarcinoma.
- Diagnostic samples are a viable source for detecting K-ras mutations relevant to lung cancer.
