Development of an ObLiGaRe Doxycycline Inducible Cas9 System for Pre-Clinical Cancer Drug Discovery

The generation of a tightly controlled ObLiGaRe doxycycline inducible SpCas9 (ODInCas9) transgene and its use in targeted ObLiGaRe resulted in functional integration into both human and mouse cells culminating in the generation of the ODInCas9 mouse.

Bone Marrow Mesenchymal Stem Cells-Derived Exosomal MicroRNA-193a Reduces Cisplatin Resistance of Non-Small Cell Lung Cancer Cells via Targeting LRRC1

A549 and H1299 cell lines were screened out and their parent cells and drug-resistant cells were co-cultured with human bone marrow mesenchymal stem cells-derived exosomes that had been transfected with miR-193a mimic or si-LRRC1 to detect the colony formation, migration, apoptosis, invasion and proliferation of non-small cell lung cancer cells.

FGFR1 Is Critical for Rbl2 Loss-Driven Tumor Development and Requires PLCG1 Activation for Continued Growth of Small Cell Lung Cancer

Researchers showed that increased fibroblast growth factor receptor 1 (FGFR1) promoted tumorigenic progression in precancerous neuroendocrine cells and is required for small cell lung cancer development in vivo.

Expression and Role of p16 and GLUT1 in Malignant Diseases and Lung Cancer: A Review

Non‐small cell lung cancer (NSCLC) is the leading cause of cancer death and in most cases it is often diagnosed at an advanced stage. Many genetic and microenvironmental factors are able to modify the cell cycle inducing carcinogenesis and tumor growth.

Janssen Presents Findings from Global, Multi-Center Trial Examining Amivantamab in Combination with Lazertinib in Patients with EGFR-Mutated Non-Small Cell Lung Cancer

The Janssen Pharmaceutical Companies of Johnson & Johnson announced interim results from the CHRYSALIS study, evaluating amivantamab, a fully human bispecific antibody that targets epidermal growth factor receptor (EGFR) and mesenchymal epithelial transition factor mutations, in combination with the third-generation EGFR tyrosine kinase inhibitor lazertinib in patients with non-small cell lung cancer with EGFR exon 19 deletions or L858R mutations.

CB11, a Novel Purine-Based PPARɣ Ligand, Overcomes Radio-Resistance by Regulating ATM Signaling and EMT in Human Non-Small-Cell Lung Cancer Cells

CB11 caused cell death via reactive oxygen species-mediated ATM-p53-GADD45α signaling in human non-small-cell lung cancer cells, and diphenyleneiodonium, an NADPH oxidase inhibitor, decreases cell death by inhibiting CB11-mediated ATM signaling.
