Early stages of lung cancer could be detected with a simple blood test

Scientists at the MRC's Toxicology Unit at the University of Cambridge analysed the blood tests of mice with a genetic mutation known as KRAS, which replicates the early signs of lung cancer.

Authors: Jin Q, Zhou J, Xu X, Huang F, Xu W Abstract The majority of patients with non-small cell lung cancer (NSCLC) with activating epidermal growth factor receptor (EGFR) mutations inevitably progress in stage despite an initial substantial and rapid response to EGFR-tyrosine kinase inhibitors (EGFR-TKIs). Previous research indicates that hypoxia may be associated with resistance to EGFR-TKIs in EGFR mutation-positive NSCLC. Therefore, the present study regulated the activity of hypoxia-inducible factor-1 (HIF-1) signaling pathway to observe if it is able to alter the sensitivity of lung cancer cells to gefitini...

Authors: Zhang Q, Nong J, Wang J, Yan Z, Yi L, Gao X, Liu Z, Zhang H, Zhang S Abstract The aim of the present study was to develop a procedure for the isolation of circulating tumor cells (CTCs), and to evaluate its application in the detection of epidermal growth factor receptor (EGFR) mutations, and potential heterogeneity in patients with non-small-cell lung cancer (NSCLC). Peripheral blood samples were collected from 91 patients with lung cancer, 10 patients with benign disease and 10 healthy volunteers. CTCs were enriched by positive immunomagnetic separation, detected by immunocytochemistry, and processed for...

Authors: Yuan T, Zhang F, Zhou X, Li Y, Zhang Y, Xu Y, Wang X Abstract Proteasome inhibitors represent a novel class of drugs that have clinical efficacy against hematological and solid cancer types, including acute myeloid leukaemia, myelodysplastic syndrome an non-small cell lung cancer. It has been demonstrated that the anti-apoptotic protein B-cell lymphoma-2-associated athanogene 3 (BAG3) is induced by proteasome inhibitors in various cancer cells and serves an important role in chemotherapy resistance. The phosphatidylinositol 3-kinase (PI3K)/RAC-α serine/threonine-protein kinase (AKT) pathway is consti...

In total, 80 pulmonary lung major resections (including lobectomy and segmental resections) with systematic mediastinal lymphadenectomy were retrospectively analyzed. Patients were randomly divided into an observation group and a control group. In the observation group, the device was...

Abstract Lung cancer is the leading cause of cancer-related death, and NSCLC constitutes nearly 85% – 90% of all cases. The IRS proteins function as adaptors and transmit signals from multiple receptors. Upon binding of insulin to the insulin receptor (IR), IRS1 is phosphorylated at several YXXM motifs creating docking sites for the binding of PI3Kp85, which activates AKT kinase. Therefore, we thought that gain of function mutantions of IRS1 could be related to development of lung cancer. In line with this, we wanted determine whether the IRS1 gene was mutated in the coding regions surrounding YXXM motifs. We sequenc...

Abstract KRAS G12D point mutation plays an important role in the incidence of non-small-cell lung cancer (NSCLC) as well as colorectal cancer, pancreatic cancer and breast cancer. Here, we developed a novel anchor-like DNA (alDNA) electrochemical sensor for the detection of KRAS point mutation level (the concentration ratio of the specific KRAS point mutant DNA (M-DNA) to the total DNA (t-DNA) of both mutant and wild-type DNAs carrying the same allele). Compared to those conventional ligation-based DNA sensors, the proposed alDNA sensor achieved the one-step capture of both wild-type and mutant DNA, and the subseq...
