ABSTRACT BACKGROUND: In Brazil, particularly in the underdeveloped localities, the prevalence of Helicobacter pylori (H. pylori) infections can range up to 90%. These rates are higher in older individuals and vary by country region. H. pylori infections are linked to the development of gastric pathologies, namely mild to moderate gastritis, gastroenteritis, peptic ulcer, intestinal metaplasia, and gastric cancer. In 1994, this organism was classified by the International Agency for Research on Cancer (IARC) as pertaining to the Group 1 carcinogen for gastric adenocarcinoma etiology. Gastric cancer represents a significant ...

Authors: Kim J, Bae DH, Kim JH, Song KS, Kim YS, Kim SY Abstract Homeodomain‑containing gene 10 (HOXC10) is a member of the homeobox transcription factors that plays an important role in the development of multicellular organisms. HOXC10 is overexpressed in a variety of human cancers, and recent studies have revealed that HOXC10 is upregulated in gastric cancer as well. However, its mechanism of action is not fully understood, thus, the role of HOXC10 was investigated in the present study in human gastric cancer. First, HOXC10 expression was revealed to be significantly increased in gastric cancer tissues compare...

TFAP2E methylation promotes 5‑fluorouracil resistance via exosomal miR‑106a‑5p and miR‑421 in gastric cancer MGC‑803 cells. Mol Med Rep. 2019 May 14;: Authors: Jingyue S, Xiao W, Juanmin Z, Wei L, Daoming L, Hong X Abstract Hypermethylation of transcription factor activating enhancer‑binding protein 2e (TFAP2E) has been reported to be associated with chemoresistance to 5‑fluorouracil (5‑FU) in gastric cancer (GC). In the present study, the molecular mechanism governing this chemoresistance was investigated. Drug‑resistant human GC MGC‑803/5‑FU cells were established and TFAP2E exp...

Authors: Liu Y, Li Y, Zhao Y, Liu Y, Fan L, Jia N, Zhao Q Abstract Interleukin enhancer‑binding factor 3 (ILF3) may function as a transcriptional coactivator and has been reported to be involved in tumor proliferation and metastasis; however, its role and clinical value in gastric cancer (GC) remains unclear. To understand the value of ILF3 in GC, a total of 80 matched samples selected from GC tissues and the adjacent mucosa were used to evaluate the expression of ILF3 and its association with clinical characteristics. Furthermore, its biological functions and mechanisms were investigated using SGC‑7901 and BGC...

Publication date: August 2019Source: Biochimica et Biophysica Acta (BBA) - Reviews on Cancer, Volume 1872, Issue 1Author(s): Cheng-Bei Zhou, Jing-Yuan FangAbstractPyroptosis, a type of inflammatory programmed cell death, is mediated by multiple inflammasomes which can recognize danger signals and activate the secretion of pro-inflammatory cytokines like IL-181 and IL-1β2. It can induce cancer cell death within the gastrointestinal tract. NLRs3, AIM24, GSDM5 family play important roles in pyroptosis signaling pathways in intestinal cancer such as gastric cancer, colitis-associated colorectal cancer and esophageal cance...

Authors: Vázquez-Ibarra KC, Bustos-Carpinteyro AR, García-Ruvalcaba A, Magaãa-Torres MT, Gutiérrez-Aguilar R, Marín-Contreras ME, Santiago-Luna E, Sánchez-López JY Abstract Gastric cancer (GC) is the third most lethal type of cancer worldwide. Single nucleotide polymorphisms (SNPs) in regulatory sites or coding regions can modify the expression of genes involved in gastric carcinogenesis, as ERBB2, which encodes for the tyrosine-kinase receptor HER-2. The aim of this work was to analyze the association of the polymorphisms: rs2643194, rs2517951, rs2643195, rs2934971,...

The precise role of PD-1/PD-L1 inhibition of the immune response in GC is unknown. The study investigated PD-1 and PD-L1 expression on peripheral T-cells and its potential association with clinicopathological features in gastric cancer (GC) patients. Material and methods: PD-1/PD-L1 expression on CD4(+...
