Knowledge, Attitudes, and Practices Among Thoracic Healthcare Professionals Toward Postoperative Pulmonary Embolism.

Postoperative pulmonary embolism (PPE) is a critical complication that can significantly affect patient outcomes. This study aimed to assess knowledge, attitudes, and practices (KAP) of thoracic healthcare professionals toward PPE. A cross-sectional study was conducted from September to December 2022.

A novel mitochondrial metabolism-related gene signature for predicting the prognosis of oesophageal squamous cell carcinoma.

Oesophageal squamous cell carcinoma (ESCC) is one of the most lethal cancers worldwide. Due to the important role of mitochondrial metabolism in cancer progression, a clinical prognostic model based on mitochondrial metabolism and clinical features was constructed in this study to predict the prognosis of ESCC. Firstly, the mitochondrial metabolism scores (MMs) were calculated based on 152 mitochondrial metabolism-related genes (MMRGs) by single sample gene set enrichment analysis (ssGSEA).

Exosomal lncCRLA is predictive for the evolvement and development of lung adenocarcinoma.

Lung adenocarcinoma, the most common histological subtype of non-small cell lung cancer, exhibits heterogeneity that enables adaptability, limits therapeutic success, and remains incompletely understood. Our team uncovers that lncRNA related to chemotherapy resistance in lung adenocarcinoma (lncCRLA) is preferentially expressed in lung adenocarcinoma cells with the mesenchymal phenotype. lncCRLA can not enhance chemotherapy resistance in lung adenocarcinoma due to its binding to RIPK1 in exosomes, which is released into intercellular media and transferred by exosomes from mesenchymal-like to epithelial-like cells.

Hsa-miR-1269a up-regulation fosters the malignant progression of esophageal squamous cell carcinoma via targeting FAM46C.

Esophageal squamous cell carcinoma (ESCC) is a malignancy of the alimentary tract resulting in death worldwide. The role and underlying mechanism of hsa-miR-1269a in the progression of ESCC remain unclear. In this study, hsa-miR-1269a was screened by differential expression analysis in TCGA, and its target gene FAM46C was predicted.

TMED3 exerts a protumor function in non-small cell lung cancer by enhancing the Wnt/β-catenin pathway via regulation of AKT.

Transmembrane emp24 protein transport domain containing 3 (TMED3) is a newly identified cancer-related protein in several malignancies. However, its role in carcinogenesis is still controversial. The project was performed to explore the possible function of TMED3 in the carcinogenesis of non-small cell lung cancer (NSCLC).

lncCRLA Enhanced Chemoresistance in Lung Adenocarcinoma That Underwent EpithelialMesenchymal Transition.

EMT confers increased metastatic potential and the resistance to chemotherapies to cancer cells. However, the precise mechanisms of EMT-related chemotherapy resistance remain unclear. c-Src-mediated caspase 8 phosphorylation essential for EMT in lung adenocarcinoma cell lines preferentially occurs in cells with the mesenchymal phenotype, resulting in chemoresistance to cisplatin plus paclitaxel in patients with resectable lung adenocarcinoma and a significantly worse 5-year PFS.

SphK1 promotes development of non‑small cell lung cancer through activation of STAT3.

Sphingosine kinase1 (SphK1) is an oncogenic enzyme that regulates tumor cell apoptosis, proliferation and survival. SphK1 has been reported to promote the development of non‑small cell lung cancer (NSCLC), although the underlying mechanism remains to be determined. The aim of the present study was to examine the expression and function of SphK1 in NSCLC and to explore the underlying molecular mechanism.

Circular RNA SMARCA5 suppressed non-small cell lung cancer progression by regulating miR-670-5p/RBM24 axis.

Circular RNAs (circRNAs) have good stability and long half-life in blood and other body fluid, and possess regulatory effects on various biological processes as miRNA/RNA-binding protein sponges, or by competing endogenous RNA, indicating their great potential as biomarkers or targets of cancer therapy. In this study, we mainly explored the role and mechanism of circular RNA SMARCA5 (circsSMARCA5) in non-small cell lung cancer (NSCLC). Quantitative RT-PCR was applied to measure the expression levels of genes, and then, the relationships among circsSMARCA5, microRNA-670-5p (miR-670-5p), and RBM24 were further analyzed.

Targeting Aurora kinase B attenuates chemoresistance in glioblastoma via a synergistic manner with temozolomide.

Background: Recent studies have demonstrated that aberrant expression or activation of kinases results in oncogenesis of a wide range of cancers including GBM. Inhibition of kinases expression induces a reduction of therapy resistance. In this study, we investigate the underlying mechanism by which glioblastoma (GBM) cells acquire resistance to Temozolomide (TMZ) through Aurora kinase B (AURKB) thus to identify novel therapeutic targets and prognostic biomarkers for GBM.

RNF43 ubiquitinates and degrades phosphorylated E-cadherin by c-Src to facilitate epithelial-mesenchymal transition in lung adenocarcinoma.

Background: In epithelial cells, tyrosine kinases induce tyrosine phosphorylation and ubiquitination of the E-cadherin complex, which is responsible for the epithelial-mesenchymal transition (EMT). However, the precise mechanisms remain unclear.

Methods: Protein antibody microarray analysis and E3 ligase profiling were performed to detect the unique E3 ligase underlying E-cadherin downregulation in lung adenocarcinoma tissues.

Silencing of Rab3D suppresses the proliferation and invasion of esophageal squamous cell carcinoma cells.

Rab3D is a member of the ras-related GTP-binding protein Rab family and was found up-regulated in several types of cancer. However, little is known about the role of Rab3D in carcinogenesis and progression of esophageal squamous cell carcinoma (ESCC). Thus, in this study, we investigated the expression patterns and functional roles of Rab3D in human ESCC.

Knockdown of DDX5 Inhibits the Proliferation and Tumorigenesis in Esophageal Cancer.

DEAD (Asp-Glu-Ala-Asp) box protein 5 (DDX5), a prototypical member of the DEAD/H-box protein family, has been involved in several human malignancies. However, the expression and biological role of DDX5 in esophageal cancer (EC) remain largely unknown. In this study, we examined the role of DDX5 in regulating EC cell proliferation and tumorigenesis and explored its possible molecular mechanism.

Knockdown of Ubiquitin-Specific Protease 14 (USP14) Inhibits the Proliferation and Tumorigenesis in Esophageal Squamous Cell Carcinoma Cells.

Ubiquitin-specific protease 14 (USP14), one of three proteasome-associated deubiquitinating enzymes (DUBs), plays an essential role in the development of human carcinoma. However, to the best of our knowledge, the role of USP14 in esophageal squamous cell carcinoma (ESCC) is unknown. In the current study, we investigated the expression and role of USP14 in ESCC.
