Lung adenocarcinoma (LA) is a common non-small cell lung cancer, but effective biomarkers to diagnose early LA are still lacking. Increasing evidence has indicated that the dysregulation of microRNAs (miRNAs) play crucial roles in LA progression. miR-339-5p has been recently confirmed to exert crucial functions in various cancers. Nevertheless, molecular mechanisms and effects of miR-339-5p on LA development still remain vague. In the present research, miR-339-5p expression was downregulated in human LA tissues...

The detection of long non-coding RNA (lncRNA) is a novel method for lung cancer diagnosis. However, the diagnostic efficacy of lncRNA in different studies is inconsistent. Therefore, we conducted this meta-analysis to elucidate the diagnostic efficacy of lncRNA in identification of lung cancer including small cell lung cancer. The online PubMed, Medline, EMBASE, CNKI and Wanfang literature databases were searched to identify all related articles about the diagnostic efficacy of lncRNA for lung cancer. 28 articles including 3044 patients with lung cancer and 2598 controls were enrolled in our meta-analysis...

Lung adenocarcinoma is one of the leading causes of mortality among cancer patients worldwide and chronic obstructive pulmonary disease (COPD) is also high in death statistics. In addition, patients with chronic obstructive pulmonary disease (COPD) have high risk for developing primary lung cancer. Prevention, risk estimation and a non-invasive diagnostics are essential to decrease COPD and lung cancer mortality. Therefore, better and more accurate molecular diagnostic markers (biomarkers) are needed for the early differential diagnosis of these lung diseases to help clinicians making better therapeutic decisions...

Medical image biomarkers of cancer promise improvements in patient care through advances in precision medicine. Compared to genomic biomarkers, image biomarkers provide the advantages of being non-invasive, and characterizing a heterogeneous tumor in its entirety, as opposed to limited tissue available via biopsy. We developed a unique radiogenomic dataset from a Non-Small Cell Lung Cancer (NSCLC) cohort of 211 subjects. The dataset comprises Computed Tomography (CT), Positron Emission Tomography (PET)/CT images, semantic annotations of the tumors as observed on the medical images using a controlled vocabulary, and segmentation maps of tumors in the CT scans...

OBJECTIVES: The composition and structure of site-specific microbiota have been investigated as potential biomarkers for a variety of chronic inflammatory diseases and cancers. While many studies have focused on the changes in the airway microbiota using respiratory specimens from patients with various respiratory diseases, more research is needed to explore the microbial profiles within the distal lung parenchyma in smokers with lung cancer and/or emphysema. MATERIALS AND METHODS: To describe and contrast lung tissue-associated microbial signatures in smokers with lung cancer and/or emphysema, we employed culture-independent pyrosequencing of 16S rRNA gene hypervariable V4 region and compositional analysis in non-malignant lung tissue samples obtained from 40 heavy smokers, including 10 emphysema-only, 11 lung cancer-only, and 19 with both lung cancer and emphysema...

Immune checkpoint inhibitor (ICI) therapy had achieved significant clinical benefit in multiple malignant solid tumors, such as non-small cell lung cancer, melanoma and urothelial cancer. ICI therapy not only revolutionarily altered the treatment strategy of malignant solid tumors, but also dramatically prolonged overall survival. However, the objective response rate (ORR) of ICI therapy in second line treatment remains 20% or less. How to find patients eligible for ICI therapy by effective biomarkers became hot nowadays...

Protease-activated receptor 2 (PAR2), a G protein-coupled receptor for trypsin, contributes to growth, anti-apoptosis, and migration in lung cancer. Given that PAR2 activation in airway epithelial cells compromises the airway epithelium barrier by disruption of E-cadherin adhesion, PAR2 may be involved in epithelial-mesenchymal transition (EMT) in lung adenocarcinoma cells. Although PAR2 is known to promote the migration of lung cancer cells, the detailed mechanism of this event is still not clear. Here, we found that PAR2 is highly expressed in several lung adenocarcinoma cell lines...

Cyclic long noncoding RNAs have recently become major players in cancer biology and can serve as biomarkers for cancer diagnosis and prognosis, and as potential therapeutic targets. We explored circulating LINC00342 as a predictor of non-small cell lung cancer (NSCLC). The expression of LINC00342 in tissues, serum, PBMC, and NSCLC cell lines were screened by reverse transcription quantitative polymerase chain reaction. A multistage validation and risk score formula detection analysis was used. The effect of LINC00342 on proliferation was assessed by MTT, p53, and PTEN pathways, which were analyzed by Western blot analysis...

Bone metastasis occurs in ~40% patients with non‑small cell lung cancer (NSCLC), resulting in serious morbidity and mortality. Sclerostin domain‑containing protein 1 (SOSTDC1) has been demonstrated to be associated with the development and progression of multiple types of cancer. However, the role of SOSTDC1 in NSCLC bone metastasis remains unclear. In the present study, it was identified that SOSTDC1 was downregulated in NSCLC bone metastatic lesions compared with that in primary tumors, and low SOSTDC1 expression predicted poor prognosis for patients with NSCLC...

MicroRNA‑3666 (miR‑3666) acts as a tumor suppressor in cervical cancer, non‑small cell lung cancer and thyroid carcinoma; however, the function of miR‑3666 in colorectal cancer (CRC) remains largely unknown. In the present study, was demonstrated that miR‑3666 was significantly downregulated in CRC tissues compared with in adjacent normal tissues by reverse transcription‑quantitative polymerase chain reaction. Additionally, miR‑3666 may serve as a prognostic biomarker for patients with CRC. Via functional experiments, the present study reported that miR‑3666 overexpression significantly inhibited the proliferation, migration and invasion of CRC cells as determined by Cell Counting Kit‑8 and Transwell assays, and vice versa...

Long noncoding RNAs (lncRNAs) have been demonstrated to play significant roles in hepatocellular carcinoma (HCC) tumor progression. LINC01433 has been implicated in the progression of lung cancer. However, its biological role in HCC remains poorly understood. In our current study, we focused on the detailed mechanism of LINC01433 in HCC development. First, it was exhibited that LINC01433 was remarkably elevated in HCC cells, which indicated that LINC01433 was involved in HCC. Then, knockdown of LINC01433 was able to restrain HCC cell proliferation and cell colony formation and greatly induced cell apoptosis...

Circulating tumor cells (CTCs) from peripheral blood of cancer patients are considered as one of the most promising pharmacodynamic (PD) biomarkers due to its non-invasive property in disease diagnosis and prognosis. However, the detection of extremely low number of CTCs in patient blood requires methods with high sensitivity and accuracy. We fabricated an arrayed geometrically enhanced mixing (GEM) chip with a "dislocation herringbone" layout based on cell immunoaffinity. By optimizing the injection and rinsing flow rate, an average cell capture rate of 87...
