Helicobacter pylori (H. pylori) is one of the most common human pathogens, affecting half world’s population. Approximately 20% infected patients develop gastric ulcers or neoplastic changes in stroma. An infection also leads to progression epithelial–mesenchymal transition within tissue, increasing probability cancer development. This paper aims review role H. and its virulence factors associated with malignant transformation The reviewed included: CagA (cytotoxin-associated gene A) along induction stem-cell properties interaction YAP (Yes-associated protein pathway), tumor necrosis factor α-inducing protein, Lpp20 lipoprotein, Afadin penicillin-binding 1A, microRNA-29a-3p, programmed cell death 4, lysosomal-associated transmembrane 4β, cancer-associated fibroblasts, heparin-binding epidermal growth (HB-EGF), matrix metalloproteinase-7 (MMP-7), stem cells (CSCs). summarizes recent findings, providing insight into potential molecular targets new treatment strategies for cancer.

Upon immunogenic challenge, lymph nodes become mechanically stiff as immune cells activate and proliferate within their encapsulated environments, with resolution, they reestablish a soft baseline state. Here we show that sensing these mechanical changes in the microenvironment requires mechanosensor YAP. YAP is induced upon activation suppresses metabolic reprogramming of effector T cells. Unlike other cell types which promotes proliferation, proliferation stiffness-dependent manner by directly restricting translocation NFAT1 into nucleus. slows responses systemic viral infections retards autoimmune diabetes. Our work reveals paradigm whereby tissue mechanics fine-tune adaptive health disease.

Helicobacter pylori causes persistent infection in the gastric epithelium of more than half world’s population, leading to development severe complications such as peptic ulcer diseases, cancer, and mucosa-associated lymphoid tissue (MALT) lymphoma. Several virulence factors, including cytotoxin-associated gene A (CagA), which is translocated into via type 4 secretory system (T4SS), have been indicated play a vital role disease development. Although with strains harboring East Asian CagA possessing EPIYA-A, -B, -D sequences has found potentiate cell proliferation pathogenicity, exact mechanism involvement severity still remains be elucidated. Therefore, we discuss possible pathogenicity.

The Hippo signaling pathway is involved in tissue size regulation and tumorigenesis. Genetic deletion or aberrant expression of some genes lead to enhanced cell proliferation, tumorigenesis, cancer metastasis. Recently, multiple studies have identified a wide range upstream regulators the pathway, including mechanical cues ligands G protein-coupled receptors (GPCRs). Through activation related proteins possibly rearrangements actin cytoskeleton, GPCR can potently modulate phosphorylation states activity YAP TAZ, two homologous oncogenic transcriptional co-activators, major effectors pathway. Herein, we summarize network, regulation, functions GPCR-Hippo signaling, will also discuss potential anti-cancer therapies targeting GPCR-YAP signaling.
