Overall, the odds ratio to develop lung cancer was almost three times greater for women than for men, DNA adduct levels were higher among females than in males and mutations in the tumor suppressor gene p53 and the proto-oncogene K-RAS were more frequently found in women than in men.
Several growth related genes such as EGFR and VEGF as well as tumour suppressor genes such as p53 have been implicated in LC pathogenesis and progression.
TP53 mutations with 0.05-1.0% VAF were more prevalent (p < 0.05) and also enriched for tobacco smoke and age-associated mutation signatures in normal AEC from lung cancer cases compared to non-cancer controls matched for smoking and age.
Therefore, although smoking-related lung cancer unequivocally arises due to the mutagenic environment induced by tobacco carcinogens, this perspective provides a rationale for the preferential selection of lung-enriched V157, R158, and A159 mutant p53.
Our previous study found that two novel cancer-related genes, PRR11 and SKA2, constituted a classic gene pair that was regulated by p53 and NF-Y in lung cancer.
In contrast, the expression of p53‑R248Q decreased the motility and invasiveness of the breast and lung cancer cells in a p53 transactivation‑dependent manner.
These results indicated that mt p53 might accelerate the recurrence of lung cancer by regulating the self-renewal kinetics of Cr-LCSCs as well as the recruitment of macrophages.
It is shown that this biosensor preferentially reports on the p53R248Q mutant in the PC9 lung cancer cell line compared with other lung cancer cell lines harbouring either wild-type or no p53.
Autophagy Regulated by Gain of Function Mutant p53 Enhances Proteasomal Inhibitor-Mediated Cell Death through Induction of ROS and ERK in Lung Cancer Cells.
Background The prognostic value of TP53 commutation in epidermal growth factor receptor (EGFR) mutant lung cancer is controversial and we therefore conducted this systematic review and meta-analysis.
The present study was aimed to explore the effect of S100A6 on the proliferation, invasion, migration and angiogenesis in lung cancer cell lines with the change of miR-193a expression and P53 acetylation.
SIGNIFICANCE: These studies identify TET1 as an oncogene in lung cancer whose gain of function following loss of p53 may be exploited by targeted therapy-induced senescence.<i>See related commentary by Kondo, p. 1751</i>.
Co-occurring genomic alterations, particularly in tumour suppressor genes such as TP53 and LKB1 (also known as STK11), have emerged as core determinants of the molecular and clinical heterogeneity of oncogene-driven lung cancer subgroups through their effects on both tumour cell-intrinsic and non-cell-autonomous cancer hallmarks.
The WWOX/TIAF1/p53 triad-mediated cancer suppression was determined by measuring the extent of cell migration, anchorage-independent growth, SMAD promoter activation, and apoptosis. p53-deficient lung cancer cell growth in nude mice was carried out to assess the tumor suppressor function of ectopic p53 and/or WWOX.
