Taken together, miR-10a targets PTEN to mediate the anti-tumor effect of icaritin in A549 cells, which provides a novel insight into the anti-tumor mechanism of icaritin and may provide a new strategy for lung cancer therapy.
Consistent with these findings, we observed increased PTEN phosphorylation and reduced nuclear PTEN levels in lung cancer patient samples establishing phosphorylation as a bona fide inactivation mechanism for PTEN in lung cancer.
Loss of PTEN function has been detected frequently in different forms of cancers, such as breast, prostate and lung cancer, gastric and colon cancer, skin cancer, as well as endometrial carcinoma.
Other driver biomarkers in lung cancer (point mutations and rearrangements in specific genes including Her2, BRAF, NUT, MET, ROS1, DDR2, FGFR1, KRAS, and PTEN) might potentially provide additional information for clinical decision making.
Our findings indicate that NEDD4-1 plays a critical role in the development of NSCLC and provides novel insight on the mechanisms that contribute to inactivate PTEN in lung cancer.
The deubiquitylase OTUD3 plays a suppressive role in breast tumorigenesis through stabilizing PTEN protein, but its role in lung cancer remains unclear.
Using single stranded conformation polymorphism (SSCP) analysis, we screened the PTEN/MMAC1 open reading frame of 53 lung cancer cell line cDNAs for point mutations and found that 3/35 SCLCs and 3/18 NSCLCs contained homozygous amino acid sequence altering mutations.
Recent evidence suggests that downregulation of gene of phosphatase and tensin homolog deleted on chromosome 10 plays an important role in acquired resistance to epidermal growth factor receptor-tyrosine kinase inhibitors in various types of cancers, including lung cancer.
We have developed a Drosophila lung cancer model by targeting Ras1(G12V)--alone or in combination with PTEN knockdown--to the Drosophila tracheal system.
