Aim: To understand the molecular difference between negative and positive gastric cancer, a regulatory network analysis is investigated.
Background: Helicobacter pylori as the one of the most leading causes of gastric cancer is yet to be studied in terms of its molecular pathogenicity.
Methods: Cytoscape version of 3.7.2 with its applications was employed to conduct this study via corresponding algorithms.
Results: A total of 161 microRNAs were identified differentially expressed in the comparison of two groups of gastric cancer including negative and positive with infection. CluePedia explored the regulatory network and found down-regulation dominant while considering the linked hub genes.
Conclusion: It can be concluded that the presented microRNAs and target genes could have associations with carcinogenesis in gastric cancer through dysregulation of some vital biological processes. These microRNAs and target genes include hsa-miR-943, hsa-miR-935, hsa-miR-367, hsa-miR-363, hsa-miR-25, and hsa-miR-196b and ADRA1A, KCNA4, SOD1, and SESN3, respectively. However, verification analysis in this regard is required to establish these relationships.

Delta-like protein (DLL3) is a novel therapeutic target. DLL3 expression in gastroenteropancreatic neuroendocrine tumors (GEP-NECs) is poorly understood, complicating the distinction between well-differentiated neuroendocrine tumors G3 (NET G3) and poorly differentiated NEC. DLL3 immunohistochemistry (IHC) was performed on 248 primary GEP-NECs, correlating with clinicopathological parameters, NE markers, PD-L1, Ki67 index, and prognosis.

Activation of the p38 mitogen-activated protein kinase (MAPK) pathways is vital in regulating cell growth, differentiation, apoptosis, and stress response, significantly affecting tumorigenesis and cancer progression. We developed a bioinformatic technique to construct an interactome network-based molecular pathways for genes of interest and quantify their activation levels using high-throughput gene expression data. This study is focused on the p38α, p38β, p38γ, and p38δ kinases, examining their activation levels (PALs) based on transcriptomic data and their associations with survival and drug responsiveness across various cancer types.

Introduction: Histone deacetylase inhibitors (HDACi) have shown promising preclinical activity in gastric cancer cells; unfortunately, however, these could not be confirmed in clinical trials. This highlights the need for the identification of underlying reasons, which may also provide the basis for possible combination therapies. Here, we delineated the effects of HDACi on components of EGFR signalling in gastric cancer cells.

Background: Motile sperm domain containing 1 (MOSPD1) is overexpressed in colorectal, prostate, and breast cancers, but its role in gastric cancer (GC) progression remains unclear.
Methods: The effect of MOSPD1 was evaluated using cell viability, colony formation, wound healing, and Transwell assays. Triglyceride and lipid levels were measured in GC cells.

Introduction: Advances in treatment strategies for gastric and esophageal cancer have led to improved long-term outcomes, however the local and systemic effects of tumor growth, neoadjuvant therapies and surgery, results in specific nutritional challenges. Comprehensive nutritional evaluation and support represents a core component of multidisciplinary holistic care for this patient population.
Areas Covered: This review provides a detailed overview of the nutritional challenges in gastric and esophageal cancer, with a focus on malignant obstruction, preoperative optimization and nutrition in survivorship.
