(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) Fibroblast growth factor (FGF) 10 is essential for lung morphogenesis and polymorphisms in the Fgf10 region are linked with higher susceptibility towards COPD in human patients. We found that FGF10 signaling is impaired in lung septal wall compartment from COPD patients. Mice with impaired FGF10 signaling (Fgf10+/-) were more prone to develop cigarette smoke (CS)-induced emphysema and pulmonary hypertension (PH). 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.

(Submitter supplied) Objectives: Systemic inflammatory response syndrome (SIRS) is a frequent complication of cardiopulmonary bypass (CPB). 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...

(Submitter supplied) Metastases in the brain are the most severe and devastating complication of cancer. The incidence of brain metastasis is increasing. Therefore, the need of finding specific druggable targets for brain metastasis is demanding. The aim of this study was to compare the brain (immune) response to brain metastases of the most common tumor lineages, viz., lung adenocarcinoma and breast cancer. Targeted gene expression profiles of 11 brain metastasis of lung adenocarcinoma (BM-LUAD) were compared to 11 brain metastasis of breast cancer (BCBM) using NanoString nCounter PanCancer IO 360™ Panel. more...

(Submitter supplied) Lung adenocarcinoma (LUAD) is one of the most common pathological and histological subtypes of primary lung cancer, with high morbidity and mortality. MicroRNAs (miRNAs) are endogenous small non-coding RNAs that regulate the expression of genes at post-transcriptional level. It was reported that A-to-I miRNA editing was decreased in tumors, suggesting the potential value of miRNA editing in cancer classification. more...

(Submitter supplied) Qing-Jin-Hua-Tan decoction (QJHTD) is a classic traditional Chinese medicine (TCM) prescription that has proven appropriate for the treatment of inflammatory lung diseases including chronic obstructive pulmonary disease (COPD), but its mechanism of action on COPD is still perplexing. We aim to explore the molecular machinery underpinning the curative effects of QJHTD on COPD. We confirmed in vitro anti-apoptotic and anti-inflammatory activities of QJHTD using the BEAS-2B and RAW264.7 cells challenged by cigarette smoke (CS) extract (CSE) and lipopolysaccharide (LPS) after chemical analysis of QJHTD. more...
