Developing and validation a prognostic model for predicting prognosis among synchronous colorectal cancers patients using combined log odds ratio of positive lymph nodes: a SEER database study.

Purpose: The aim of the study is to identify risk factors for the prognosis and survival of synchronous colorectal cancer and to create and validate a functional Nomogram for predicting cancer-specific survival in patients with synchronous colorectal cancer.

Methods: Synchronous colorectal cancers cases were retrieved from the Surveillance, Epidemiology, and End Results database retrospectively, then they were randomly divided into training (n = 3371) and internal validation (n = 1440) sets, and a set of 100 patients from our group was used as external validation. Risk factors for synchronous colorectal cancer were determined using univariate and multivariate Cox regression analyses, and two Nomograms were established to forecast the overall survival and cancer-specific survival, respectively.

Antitumor Activity of a Bispecific Chimera Targeting EGFR and Met in Gefitinib-Resistant Non-Small Cell Lung Cancer.

Non-small cell lung cancers (NSCLC) frequently acquire resistance to tyrosine kinase inhibitors (TKI) due to epidermal growth factor receptor (EGFR) mutation or activation of the bypass pathway involving mesenchymal-epithelial transition factor (Met). To address this challenge, a bispecific nanobody-aptamer chimera is designed to target mutated EGFR and Met simultaneously to block their cross-talk in NSCLC. The EGFR-Met chimera is cost-effectively engineered using microbial transglutaminase and click chemistry strategies.

Identification of serum tsRNA-Thr-5-0015 and combined with AFP and PIVKA-II as novel biomarkers for hepatocellular carcinoma.

Accumulating evidence has shown that tRNA-derived small RNAs (tsRNAs) play crucial roles in malignant tumor development. However, whether serum tsRNAs can act as potential biological markers for hepatocellular carcinoma (HCC) are still largely unknown. In the current study, a novel tsRNA, namely tsRNA-Thr-5-0015, was prominently elevated in the sera of HCC patients than that of hepatitis cases and healthy check-ups, and it was related with TNM stage and lymphatic metastasis of HCC patients.

KRT80 in hepatocellular carcinoma plays oncogenic role via epithelial-mesenchymal transition and PI3K/AKT pathway.

Hepatocellular carcinoma (HCC), a globally prevalent form of cancer, is featured by aggressive growth and early metastasis.

Piezo1 Mediates Glycolysis-Boosted Pancreatic Ductal Adenocarcinoma Chemoresistance within a Biomimetic Three-Dimensional Matrix Stiffness.

Pancreatic ductal adenocarcinoma (PDAC) is a lethal cancer with a very low 5-year survival rate, which is partially attributed to chemoresistance. Although the regulation of chemoresistance through biochemical signaling is well-documented, the influence of three-dimensional (3D) matrix stiffness is poorly understood. In this study, gelatin methacrylate (GelMA) hydrogels were reconstructed with stiffnesses spanning the range from normal to cancerous PDAC tissues, which are termed as the soft group and stiff group.

Mechanisms of Action of HSP110 and Its Cognate Family Members in Carcinogenesis.

Tumors, as chronic malignant diseases that account for about 20% of all deaths worldwide, are the number one threat to human health. Until now there is no reliable treatment for most types of tumors. Tumorigenesis and cellular carcinogenesis remain difficult challenges due to their complex etiology and unknown mechanisms.

Neutrophil membrane-coated nanoparticles for targeted delivery of toll-like receptor 4 siRNA ameliorate LPS-induced acute lung injury.

Pulmonary delivery of small interfering RNAs (siRNAs) is an effective treatment for acute lung injury (ALI), which can modulate the expression of pro-inflammatory cytokines and alleviate the symptoms of ALI. However, the rapid degradation of siRNA in vivo and its limited ability to target and validate cells are important challenges it faces in clinical practice. In this work, we developed neutrophil membrane-coated Poly (lactic-co-glycolic acid) nanoparticles loaded with TLR4 siRNA (si-TLR4) (Neutrophil-NP-TLR4), which can target both inflammatory and macrophage cells to alleviate the pulmonary inflammation in lipopolysaccharide (LPS)-induced ALI mice.
