MicroRNAs (miRNAs) have been identified as promising cancer biomarkers due to their stable presence in serum. As an alternative PCR-based homogenous assays, surface-based electrochemical biosensors offer great opportunities for low-cost, point-of-care tests (POCTs) of disease-associated miRNAs. Nevertheless, the sensitivity miRNA sensors is often limited by mass transport and crowding effects at water-electrode interface. To address such challenges, we herein report a DNA nanostructure-based...

As an early type of lung adenocarcinoma, ground glass nodule (GGN) has been detected increasingly and now accounts for most cancer outpatients. GGN a satisfactory prognosis its characteristics are quite different from solid adenocarcinoma (SADC). We compared the (GGN-ADC) with SADC using single-cell RNA sequencing (scRNA-seq) to fully understand GGNs. The tumor samples five patients GGN-ADCs SADCs underwent surgery were digested suspension analyzed 10× Genomic scRNA-seq techniques. obtained...

Abstract Background Lung adenocarcinoma (LUAD) patients with different American Joint Committee on Cancer stages have overall 5‐year survival rates. The tumor microenvironment (TME) and intra‐tumor heterogeneity (ITH) been shown to play a crucial role in the occurrence development of tumors. However, TME ITH lesions LUAD not extensively explored. Methods We present 204,157‐cell catalog transcriptome 29 lung samples systematically explore LUAD. Traditional RNA sequencing data complete...

Most cancer cells have fundamentally different metabolic characteristics, particularly much higher glycolysis rates than normal tissues, which support the increased demand for biosynthesis and promote tumor progression. We found that transforming growth factor (TGF)-β plays a dual function in regulating cell proliferation non-small lung cancer.We used PET/MRI imaging system to observe glucose metabolism of subcutaneous tumors nude mice. Energy lines detected by Seahorse XFe96 outflow...

EGF receptor (EGFR) tyrosine kinase inhibitors (TKIs) have achieved clinical success in lung adenocarcinoma (LUAD). However, tumors often show profound but transient initial response and then gain resistance. We identify transcription factor ZNF263 as being significantly decreased osimertinib-resistant or drug-tolerant persister LUAD cells residual tumors. overexpression improves the of delays formation with osimertinib treatment. further that binds recruits DNMT1 to EGFR gene promoter,...

Immune-related adverse reactions (irAEs) are common after immune checkpoint inhibitor treatment, impacting the universality and continued use of immunotherapy. Currently, preclinical models to investigate mechanisms underlying these effects inadequate. This study aims develop both in vitro vivo irAEs advance basic research on reactions. For models, we designed two co-culture systems: "Lung epithelial cells-PBMC" conditional model "organoid-PBMCs" model. These involve culturing spheroids,...

In order to identify novel non-invasive biomarkers with high accuracy for the screening of non-small cell lung cancer (NSCLC), we investigated predictive power 4 microRNAs (miR-146, miR-204, miR-106a and miR-124) in plasma samples obtained from patients NSCLC healthy controls (n=50; training phase) by reverse transcription-quantitative polymerase chain reaction (RT-qPCR). We found that levels miR-204 were significantly dysregulated compared controls, thus this miRNA was selected further...
