Fatty acid metabolism: A new target for nasopharyngeal carcinoma therapy.

Lipid metabolic reprogramming is considered one of the most prominent metabolic abnormalities in cancer, and fatty acid metabolism is a key aspect of lipid metabolism. Recent studies have shown that fatty acid metabolism and its related lipid metabolic pathways play important roles in the malignant progression of nasopharyngeal carcinoma (NPC). NPC cells adapt to harsh environments by enhancing biological processes such as fatty acid metabolism, uptake, production, and oxidation, thereby accelerating their growth.

Baicalin ameliorates neuroinflammation by targeting TLR4/MD2 complex on microglia via PI3K/AKT/NF-κB signaling pathway.

This study aims to elucidate the target and mechanism of baicalin, a clinically utilized drug, in the treatment of neuroinflammatory diseases. Neuroinflammation, characterized by the activation of glial cells and the release of various pro-inflammatory cytokines, plays a critical role in the pathogenesis of various diseases, including spinal cord injury (SCI). The remission of such diseases is significantly dependent on the improvement of inflammatory microenvironment.

Doxorubicin prodrug for γ-glutamyl transpeptidase imaging and on-demand cancer therapy.

The γ-glutamyl transpeptidase (γ-GGT) is an important tumor marker, which has been reported to be firmly associated with the developmental stage of liver cancer. Therefore, it makes sense to image and monitor γ-GGT level and design γ-GGT-responsive prodrug for integrated diagnosis and treatment of liver cancer. Herein, we prepare a doxorubicin (Dox) prodrug for imaging γ-GGT and on-demand treating liver cancer.

Diverse perspectives on proteomic posttranslational modifications to address EGFR-TKI resistance in non-small cell lung cancer.

Non-small cell lung cancer (NSCLC) is the main histological subtype of lung cancer. For locally advanced and advanced NSCLC, epidermal growth factor receptor (EGFR) tyrosine kinase inhibitor (TKI)-targeted therapy has been the first choice for NSCLC patients with EGFR mutations. TKIs, as targeted drugs, inhibit kinase activity and autophosphorylation by competitively binding to the ATP binding site of the EGFR tyrosine kinase domain, which blocks the signal transduction mediated by EGFR and thus inhibits the proliferation of tumor cells.

Temporal and spatial trends in gastric cancer burden in the USA from 1990 to 2021: findings from the global burden of disease study 2021.

Background: Gastric cancer (GC) is a significant public health concern in the USA, and its burden is on the rise.

Methods: This study utilized the latest data from the Global Burden of Disease (GBD) study. We provided descriptive statistics on the incidence, prevalence, mortality, disability-adjusted life years (DALYs), and age-standardized rates (ASRs) of GC across the USA and states.

Validation and evaluation of the performance of QIAstat-Dx gastrointestinal panel in pooled stool samples.

In the current study, the analytical sensitivity, analytical specificity, reproducibility, anti-interferences ability, and clinical performance of the QIAstat-Dx Gastrointestinal Panel (GIP) system were evaluated using pooled stool samples. Results showed that the pooled sample test detected the selected ten targets exclusively, with no cross reaction with any other targets of common enteropathogens. The analytical sensitivity of the pooled sample test on QIAstat-Dx GIP system was 10 CFU/ml for Shigella spp.

Sclerostin as a new target of diabetes-induced osteoporosis.

Sclerostin, a protein synthesized by bone cells, is a product of the gene. Sclerostin is a potent soluble inhibitor of the WNT signaling pathway, and is known to inhibit bone formation by inhibiting osteocyte differentiation and function. Currently, sclerostin has been the subject of numerous animal experiments and clinical investigations.

Cx43 Regulates Nicotine-Induced Proliferation and Migration of Distal Pulmonary Artery Smooth Muscle Cells by the ERK1/2 Signaling Pathway.

Pulmonary hypertension is a progressive disease associated with remodeling of the pulmonary vasculature. Excessive proliferation and migration of pulmonary artery smooth muscle cells (PASMCs) play important roles in nicotine-induced vascular injury. Connexin 43 (Cx43) is involved in intracellular communication and regulation of the pulmonary vasculature.

A General Strategy to Rapid and Sensitive Determination of Five High Boiling Point Solvents in Pharmaceuticals by RP-HPLC Combined with Precipitation Method.

The difficulty on determination of high boiling point solvents, always exist due to their low vapor pressure in headspace (HS) vial. What's worse, the commonly used GC diluents, such as N, N-dimethylacetamide, 1,3-dimethyl-2-imidazolidinone, dimethyl sulfoxide, N, N-dimethylformamide and N-methylpyrrolidone are often remained in HS instrument after frequent injection into HS, thus would result in terrible positive interference problem. In this work, a fast and sensitive HPLC method in combination with a sample precipitation method, was proposed for the determination of above five high boiling point solvents in drug substances within 14.
