Low-dose apatinib optimizes the vascular normalization and enhances the antitumor effect of PD-1 inhibitor in gastric cancer.

Background: Apatinib is a tyrosine kinase inhibitor that has shown potential in combination with immune checkpoint inhibitors (ICIs) in gastric cancer (GC); however, its role in GC is unclear. This research aims to investigate the effect of low-dose apatinib in GC, and analyze the mechanisms of its underlying action.

Methods: A mouse model of GC was established, and the experimental mice were divided into different groups for different treatment: group NS (normal saline), group A (low-dose apatinib 50 mg/kg), group B (high-dose apatinib 200 mg/kg), group C [programmed cell death protein 1 (PD-1) inhibitor monotherapy], and group D (PD-1 inhibitor combined with low-dose apatinib).

Early Oral Feeding is Safe and Comfortable in Patients with Gastric Cancer Undergoing Radical Total Gastrectomy.

Data supporting the safety and clinical efficacy of early oral feeding (EOF) after total gastrectomy are limited.

miR-99b/let-7e/miR-125a cluster suppresses pancreatic cancer through regulation of NR6A1.

This experiment investigates how the miR-99b/let-7e/miR-125a cluster regulates the mechanism of NR6A1 involved in the invasive and metastatic effects of pancreatic cancer (PCa). Bioinformatics prediction and dual luciferase reporter gene assay were applied to verify the targeted relationship between miR-99b/let-7e/miR-125a and NR6A1. ASPC1 cells underwent transfection with lentiviruses to overexpress miR-99b/let-7e/miR-125a (individual or together) to explore functions of miR-99b/let-7e/miR-125a cluster governing NR6A1 in PCa.

Key Roles of p53 Signaling Pathway-Related Factors GADD45B and SERPINE1 in the Occurrence and Development of Gastric Cancer.

p53 can function as an independent and unfavorable prognosis biomarker in cancer patients. We tried to identify the key factors of the p53 signaling pathway involved in gastric cancer (GC) occurrence and development based on the genotype-tissue expression (GTEx) and the Cancer Genome Atlas (TCGA) screening. We downloaded gene expression data and clinical data of GC included in the GTEx and TCGA databases, followed by differential analysis.

Microplastic accumulation via trophic transfer: Can a predatory crab counter the adverse effects of microplastics by body defence?

Microplastics are considered detrimental to aquatic organisms due to their potential accumulation along food chains. Thus, it is puzzling why some of them appear unaffected by microplastics. Here, we assessed the contribution of water filtration and food consumption to microplastic accumulation in a predatory marine crab (Charybdis japonica) and examined the associated impacts of microplastics (particle size: 5 μm) following ingestion for one week.

Diel-cycling seawater acidification and hypoxia impair the physiological and growth performance of marine mussels.

Ocean acidification and hypoxia are concurrent in some coastal waters due to anthropogenic activities in the past decades. In the natural environment, pH and dissolved oxygen (DO) may fluctuate and follow diel-cycling patterns, but such effects on marine animals have not been comprehensively studied compared to their constant effects. In order to study the effects of diel-cycling seawater acidification and hypoxia on the fitness of marine bivalves, the thick shell mussels Mytilus coruscus were exposed to two constant levels of dissolved oxygen (2 mg/L, 8 mg/L) under two pH treatments (7.

Dual-targeting strategy using trastuzumab and lapatinib in a patient with HER2 gene amplification in recurrent metachronous metastatic gallbladder carcinoma.

Gallbladder carcinoma (GBC) is a rare and highly aggressive tumor. Early diagnosis is challenging, which results in a poor prognosis using systemic therapy. Recent studies have identified a subset of GBC patients with HER2 gene (ERBB2) amplification that could benefit from HER2-targeted therapy.

The roles of IL-6, IL-8 and IL-10 gene polymorphisms in gastric cancer: A meta-analysis.
