Project description:Lung cancer is closely associated with chronic inflammation, but the mechanism underlying such inflammation has not been clearly defined. The lung is a mucosal tissue colonized by a diverse bacterial community at the steady state, and pulmonary infections commonly present in lung cancer patients are linked to clinical outcomes. Here we provide evidence that local microbiota provoke inflammation associated with lung adenocarcinoma by activating lung-resident gamma-delta T cells. Germ-free or antibiotic-treated mice were significantly protected from lung tumor initiation and progression induced by Kras mutation and p53 loss. Mechanistically, commensal bacteria stimulated My88-dependent IL-1beta and IL-23 production from myeloid cells, inducing proliferation and activation of Vγ6+Vδ1+ γδ T cells that produced IL-17 and other effector molecules to promote inflammation and tumor cell proliferation. Our findings provide a clear link between local microbiota-immune crosstalk and lung tumorigenesis, and thereby define key cellular and molecular mediators that may serve as effective targets in lung cancer treatment and prevention.

Project description:The subject is to study the lung microbiota and the one of upper airways (UAs) (much less studied than the intestinal microbiota) in 40 patients having lung cancer. 20 patients undergo only surgical treatment, while other half receives also chemotherapy. The idea is to explore changes in microbiota of the lung, upper UAs and intestine, and potentially find associations between them. These results will serve us as a base for the future study, focused on manipulation of the microbiota by prebiotics, probiotics or symbiotics and its effect on anti-cancer treatment tolerance and effectiveness.

Project description:Commensal bacteria have been shown to influence the reactivity of immune cells in the gut and in other organs. This study aims to assess the impact of microbiota on transcription signatures in lung stroma cells. Samples were generated from mice that were either left on plain water, on water with antibiotics, or on water with antibiotics followed by faecal transplant to reverse the antibiotics effect. CD45 negative cells were MACS-purified from the lung, and RNA seq was performed on samples.

Project description:Even though small cell lung cancer (SCLC) has entered the age of broad genomic analysis, platinum-based chemotherapy remains the standard care for SCLC. Topotecan is the only approved agent for recurrent or progressive SCLC (1). In the absence of well-defined genomic biomarkers, clinical efficacy signals in genomically distinct subsets of SCLC could have been missed. Serine/Arginine Splicing Factor 1 (SRSF1) is a member of SR protein family. The deleterious consequences of overexpression of the SRSF1 proto-oncogene in human cancers suggest that there are complex mechanisms and pathways underlying SRSF1-mediated transformation (2). Whole exome and transcriptome sequencing of primary tumor SCLC from 99 Chinese patients has identified SRSF1 DNA amplification and mRNA over-expression which predicts poor survival in Chinese SCLC patients. In vitro and in vivo studies have demonstrated that SRSF1 is essential for tumorigenecity of SCLC and plays a key role in DNA repair and chemo-sensitivity. We did RNAseq on 79 small cell lung cancer patients' tumor sample and 7 normal lung tissue. We normalized the RNAseq data and did differential expression analysis. The deleterious consequences of overexpression of the SRSF1 proto-oncogene in human cancers suggest that there are complex mechanisms and pathways underlying SRSF1-mediated transformation.

Project description:Lung tumors, as well as normal tumor-adjacent (NTA) tissue of non-small cell lung cancer (NSCLC) patients, were collected and subjected label-free quantitation shotgun proteomics in data-independent mode to identify differences between the tumors and adjacent tissue. By employing in-depth proteomics, we identified several pathways that are up- or downregulated in the tumors of non-small cell lung cancer patients.

Project description:Genome wide DNA methylation profiling of normal lung tissue samples. The Illumina Infinium 450k Human DNA methylation Beadchip was used to obtain DNA methylation profiles across approximately 450,000 CpGs in nor mal lung tissue samples. Samples included 244 normal lung tissue samples from lung cancer patients. Environment and Genetics in Lung Cancer Etiology EAGLE; Population-based case-control study Bisulphite converted DNA from 244 fresh-frozen primary human lung samples were hybridised to the Illumina Infinium 450k Human Methylation Beadchip v1.2. This file has 60 samples.
