Hypoxia is a common feature of lung squamous cell carcinoma (LUSC), and hypoxia-inducible factor-1 (HIF-1) overexpression is associated with poor clinical outcome in LUSC. NADH dehydrogenase 1 alpha subcomplex subunit 4-like 2 (NDUFA4L2) is a recently identified target of HIF-1, but its roles in LUSC remain unclear. Herein, the expression and regulatory mechanisms of NDUFA4L2 were investigated in LUSC, and the influences on LUSC cell oxidative metabolism and survival of NDUFA4L2 were determined.

Impaired facial expression perception is a core element in depression, but the underlying mechanism remains controversial. This event-related potential study investigated how attention modulates facial expression perception in depression using a nonclinical sample. A group of healthy controls (HC, N = 39) and a group of individuals with subsyndromal depression (SD, N = 39) categorized faces based on either facial expression (happy vs.

Contextual valence is an important dimension during value-based decision-making. Previous research has revealed behavioral and neural asymmetries between the gain context and the loss context. The present event-related potential study investigated the effects of contextual valence on neural dynamics underlying magnitude and time, two important reward dimensions, during feedback evaluation.

Uncertainty can be fractioned into risk and ambiguity psychologically and neurobiologically. However, whether and how risk and ambiguity are dissociated in terms of neural dynamics during value-based decision making remain elusive. The present event-related potential (ERP) study addressed these issues by asking participants to perform a wheel-of-fortune task either during a risky context (Experiment 1; N = 30) where outcome probability was known or during an ambiguous context (Experiment 2; N = 30) where outcome probability was unknown.

Background: The MDS1 and EVI1 complex locus (MECOM, also called PRDM3) and PR domain containing 16 (PRDM16) are two highly related zinc finger transcription factors associated with many malignancies. However, the mechanisms of MECOM and PRDM16 in prognosis and tumor immune infiltration in lung adenocarcinoma (LUAD) remain uncertain.

Methods: The Cancer Genome Atlas (TCGA), Oncomine, UALCAN, GEPIA, and TIMER databases were searched to determine the relationship between the expression of MECOM and PRDM16, clinicopathological features, immune infiltration, and prognosis in LUAD.

Idiopathic pulmonary fibrosis (IPF) is a chronic progressive disease with unknown etiology and unfavorable prognosis. Ferroptosis is a form of regulated cell death with an iron-dependent way that is involved in the development of various diseases. Whereas the prognostic value of ferroptosis-related genes (FRGs) in IPF remains uncertain and needs to be further elucidated.

Death receptor 4 (DR4) is a cell surface protein that is generally thought to mediate apoptosis upon binding to its ligand named TRAIL. However, its contribution to apoptosis resistance has also been reported. MET (or c-MET) gene amplification represents an important mechanism for acquired resistance to EGFR tyrosine kinase inhibitors (EGFR-TKIs) against EGFR mutant non-small cell lung cancer (NSCLC).

Overexpression of ETS‑homologous factor (EHF) in non‑small cell lung cancer (NSCLC) is associated with poor patient prognosis. To explore the mechanism of the effect of EHF in NSCLC, EHF expression was examined in NSCLC and its role in cell proliferation, invasion, cell cycle, and apoptosis of NSCLC cells was evaluated by overexpressing EHF and/or knocking down EHF expression in NSCLC cells and in cancer cell grafted mice . The results revealed that the knockdown of EHF expression in NSCLC with siRNA significantly inhibited cell proliferation and invasion, arrested the cell cycle at the G/G phase, and induced apoptosis, whereas overexpression of EHF in NSCLC promoted cell proliferation, tumor growth, and cancer cell migration .

Death receptor 4 (DR4), a cell surface receptor, mediates apoptosis or induces inflammatory cytokine secretion upon binding to its ligand depending on cell contexts. Its prognostic impact in lung cancer and connection between EGFR-targeted therapy and DR4 modulation has not been reported and thus was the focus of this study. Intracellular protein alterations were measured by Western blotting.

The circular RNA (circRNA) circEPSTI1 has been recently identified as a new cancer-associated circRNA in multiple types of cancer. However, the involvement of circEPSTI1 in non-small cell lung cancer (NSCLC) remains unexplored. The purpose of this study was to explore the expression pattern and function of circEPSTI1 in NSCLC.

Background: The majority of patients with non-small cell lung cancer (NSCLC) harboring activating epidermal growth factor receptor (EGFR) mutations respond well to osimertinib (AZD9291), a third-generation, mutation-selective EGFR inhibitor. The current study focuses on determining whether targeting MEK/ERK signaling prevents or delays the development of acquired resistance to osimertinib.

Methods: Drug effects on cell survival were determined by measuring cell number alterations.

Background: Lung cancer is the leading cause of cancer death in China and around the world. Early detection is key to improving the survival rate of non-small cell lung cancer (NSCLC). Alteration in glycosylation has been observed in cancers, and glycans can be a source for the development of new biomarkers for NSCLC.

The third-generation EGFR inhibitor, osimertinib (AZD9291), selectively and irreversibly inhibits EGFR activating and T790 M mutants while sparing wild-type EGFR. Osimertinib is now an approved drug for non-small cell lung cancer (NSCLC) patients with activating EGFR mutations (first-line) or those who have become resistant to 1st generation EGFR inhibitors through the T790 M mutation (second-line). Unfortunately, all patients eventually relapse and develop resistance to osimertinib.

This study was aimed to explore if lncRNA MALAT1 would modify chemo-resistance of non-small cell lung cancer (NSCLC) cells by regulating miR-197-3p and p120 catenin (p120-ctn). Within this investigation, we totally recruited 326 lung cancer patients, and purchased 4 NSCLC cell lines of A549, H1299, SPC-A-1 and H460. Moreover, cisplatin, adriamycin, gefitinib and paclitaxel were arranged as chemotherapies, and half maximal inhibitory concentration (IC50) values were calculated to evaluate the chemo-resistance of the cells.

The role of telomere in genomic stability is an established fact. Variation in leukocyte telomere length (LTL) has been considered a crucial factor that associated with age-associated diseases. To elucidate the association between LTL variation and ischemic stroke (IS) risk, we selected ten single nucleotide polymorphisms (SNPs) in three genes (TERC, TERT and RTEL1) that previously reported link to LTL, and genotyped SNPs of these genes in a case-control study.
