(Submitter supplied) Genome-wide association studies (GWAS) have identified multiple lung cancer risk loci including those that are distinct in the major histological types. However, most of these loci have not been functionally characterized. Here we employed massively parallel reporter assays (MPRA) to assess allelic transcriptional activity of risk-associated variants en masse. We tested 2,245 variants in 42 loci from 3 recent GWASs of East Asian and European populations in the context of lung adenocarcinoma and squamous cell carcinoma cells while incorporating exposure to a tobacco-smoke carcinogen, benzo[a]pyrene. more...

(Submitter supplied) The precise origin of newly formed alpha smooth muscle actin-positive (ACTA2+) cells appearing in non-muscularized vessels in the context of pulmonary hypertension (PH) is still debatable, although it is believed that they predominantly derive from pre-existing vascular smooth muscle cells (VSMCs). Here, Gli1Cre-ERT2; tdTomatoflox mice were used to lineage-trace GLI1+ cells in the context of PH using two independent models of vascular remodeling (VR) and reverse remodeling (RR): hypoxia and cigarette-smoke exposure (SE). more...

(Submitter supplied) To determine gene expression changes that contribute to the development of COPD among smokers using high-throughput RNA sequencing in the peripheral blood of COPD patients. Total RNA sequencing was investigated by prospectively collecting lung function test results and whole blood samples from smokers who visited the outpatient department of respiratory medicine at three hospitals since 2020. This study confirmed gene expression differences in non-coding RNA in COPD patients according to the degree of airflow limitation through RNA-Seq transcriptome analysis. more...

(Submitter supplied) Transcriptomic subtyping holds promise for personalized therapy in extensive stage small cell lung cancer (ES-SCLC). In this study, we aimed to assess intratumoral transcriptomic subtype diversity and to identify biomarkers associated with long-term chemoimmunotherapy benefit in human ES-SCLC. Our work highlights that high intratumoral heterogeneity, lack of consistent association with outcome, and unclear subtype-specific target expression are major challenges for SCLC subtype-based precision oncology. more...

(Submitter supplied) Dysbiosis, or changes within the microbiome, is a common feature of solid tumors, however whether this dysbiosis directly contributes to tumor development is largely unknown. We previously characterized the human lung cancer microbiome and identified the Gram-negative Acidovorax temperans as enriched in tumors and associated with smoking status and TP53 mutations. To determine if A. temperans exposure could contribute to the development of lung cancer, we investigated its effect in a genetically engineered mouse model of lung adenocarcinoma driven by mutant Kras and Tp53. more...

(Submitter supplied) Precision medicine's potential to transform complex autoimmune-disease treatment is often challenged by limited data availability and inadequate sample size when compared to the number of molecular features found in high-throughput multi-omics datasets. Addressing this issue, the novel framework PRoBeNet (Predictive Response Biomarkers using Network medicine) was developed. ProBeNet operates under the hypothesis that the therapeutic effect of a drug propagates through a protein–protein interaction network to reverse disease states. more...

(Submitter supplied) Never-smoker lung adenocarcinoma (NSLA) is prevalent in Asian populations, and is even more in women. EGFR mutations and ALK fusions are major alterations observed in NSLA. We have focused on NSLA without EGFR and ALK alteration (NENA) rather than NSLA with EGFR and ALK (EA). First, we selected 141 NSLA tissues, and performed proteogenomic analyses including the whole-genome sequencing (WGS), transcriptome, methylation EPIC array, total proteome and phosphoproteome. more...

(Submitter supplied) Background. The unknown tissue of origin in head and neck cancer of unknown primary (hnCUP) leads to invasive diagnostic procedures and unspecific and potentially inefficient treatment options for patients. The most common histological subtype, squamous cell carcinoma, can stem from various tumor primary sites, including the oral cavity, oropharynx, larynx, head and neck skin, lungs, and esophagus. DNA methylation profiles are highly tissue-specific and have been successfully used to classify tissue origin. We therefore developed a support vector machine (SVM) classifier trained with publicly available DNA methylation profiles of commonly cervically metastasizing squamous cell carcinomas (n = 1,103) in order to identify the primary tissue of origin of our own cohort of squamous cell hnCUP patient’s samples (n = 28). Methylation analysis was performed with Infinium MethylationEPIC v1.0 BeadChip by Illumina. Results. The SVM algorithm achieved the highest overall accuracy of tested classifiers, with 87%. Squamous cell hnCUP samples on DNA methylation level resembled squamous cell carcinomas commonly metastasizing into cervical lymph nodes. The most frequently predicted cancer localization was the oral cavity in 11 cases (39%), followed by the oropharynx and larynx (both 7, 25%), skin (2, 7%), and esophagus (1, 4%). These frequencies concord with the expected distribution of lymph node metastases in epidemiological studies. Conclusions. On DNA methylation level, hnCUP is comparable to primary tumor tissue cancer types that commonly metastasize to cervical lymph nodes. Our SVM-based classifier can accurately predict these cancers’ tissues of origin and could significantly reduce the invasiveness of hnCUP diagnostics and enable a more precise therapy after clinical validation.

SIRS is associated with significant morbidity and mortality, but its pathogenesis remains incompletely understood, and as a result biomarkers are lacking, and treatment remains expectant and supportive. This study aimed to understand the pathophysiological mechanisms driving SIRS induced by CPB and identify novel therapeutic targets that might reduce systemic inflammation and improve patient outcomes. more...
