We further observed that oncogenic cooperation between KRAS(G12D) and PIK3CA(H1047R) was accompanied by PI3Kα-mediated regulation of c-MYC, GSK3β, p27(KIP1), survivin, and components of the RB pathway, resulting in accelerated cell division of human or mouse lung cancer-derived cell lines.
In this study, we have investigated the delivery and transfection of wild-type (wt-) p53 and microRNA-125b (miR-125b) expressing plasmid DNA, in SK-LU-1 human lung adenocarcinoma cells as well as in Kras(G12D)/p53(fl/fl) (KP) genetically engineered mouse model of lung cancer.
Transgenic expression of activated Kras(G12D) in mouse respiratory epithelium is sufficient to induce lung adenocarcinomas; however, transcriptional mechanisms regulated by K-Ras during the initiation of lung cancer remain poorly understood.
This CLN-Ohi-MB biochip could quantify single-point mutations in KRAS mRNA (G12C, G12D, G12V) in pancreatic cancer cell-derived EVs and single-point mutations in EGFR mRNA (L858R and T790M) in lung cancer cell-derived EVs with high specificity, not achievable by conventional molecular probes.
Using the LA2 K-Ras G12D-induced model for lung cancer, we show that Kif2b expression reduces the number of chromosome segregation defects but does not change the incidence of lung tumor lesions.
To explore the potential interaction between TSC1 and KRAS activation in lung cancer, mice in which Tsc1 loss and Kras(G12D) expression occur in a small fraction of lung epithelial cells were generated.
To substantiate these results, an allitinib-sensitive lung cancer-derived cell line (H292) was transfected with plasmids carrying the two most common activating KRAS mutations (p.G12D and p.G12S).
Molecular epidemiology of EGFR and KRAS mutations in 3,026 lung adenocarcinomas: higher susceptibility of women to smoking-related KRAS-mutant cancers.
Using an inducible LSL-KRAS(G12D) model of lung cancer in vivo, we show a transient upregulation of Notch pathway activity in early tumor precursor lesions.
This study demonstrates an association between TRAIL resistance to apoptosis in human pancreatic and lung cancer cell lines and G12D K-ras(12) mutation.
Co-administration of BI-2536 and fasudil either in the LSL-KRAS(G12D) mouse model or in a patient tumour explant mouse model of KRAS-mutant lung cancer suppresses tumour growth and significantly prolongs mouse survival, suggesting a strong synergy in vivo and a potential avenue for therapeutic treatment of KRAS-mutant cancers.
Phase II study of the GI-4000 KRAS vaccine after curative therapy in patients with stage I-III lung adenocarcinoma harboring a KRAS G12C, G12D, or G12V mutation.
Since hypoxic microenvironments select for tumor cells with diminished therapeutic response, we investigated whether hypoxia unequally increases resistance to 3-BrPA in wt p53 MelJuso melanoma harbouring (Q61L)-mutant NRAS and wt BRAF, C8161 melanoma with (G12D)-mutant KRAS (G464E)-mutant BRAF, and A549 lung carcinoma with a KRAS (G12S)-mutation.
