Microbiota of gastric topographic regions in Colombian populations

Persistent inflammation in the gastric antrum caused by Helicobacter pylori (H. pylori) increases the risk of developing duodenal ulcer, in contrast, when gastritis predominates in the stomach body, generates atrophic gastritis and increased risk for the development of gastric cancer.

Preliminary results on Dietary habits, lifestyle, oral health and obesity in a case control study on adenocarcinoma gastric in Sao Paulo at A.C Camargo Cancer Center (2016-2017)

Gastric cancer is the fifth commonest incident malignancy represents 6.8% of the cancers (952,000 cases/2012)and it is the third leading cause of death by cancer for both genders worldwide 8.8% (723,000 deaths), Epidemiologic studies have shown the positive impact of the Mediterranean Diet.

A novel role for the urease virulence factor in the induction of HIF-1α activity in gastric cells by Helicobacter pylori

A recently published study from our lab demonstrated that H. pylori activation of the PI3K-AKT-mTOR pathway in gastric cells, increased hypoxia-induced factor (HIF)-1α expression, which accelerated the post-translational down-regulation of Cyclin D1.

The profile of differentially expressed piRNAs associated to the field effect theory in gastric cancer

The knowledge about carcinogenesis and the molecular events that lead to cell transformation in gastric cancer (GC) has been a challenge to the scientific community. In this way, studies involving small non-coding RNAs have been widely explored.

Circular RNAs in gastric cancer: a new field to be explored as biomarkers

ircular RNAs comprise a new class of long noncoding RNAs characterized by their 5'and 3'ends covalently joined. They were misinterpreted as splicing errors for more than 20 years until their rediscovery in 2012 as diverse, highly abundant, conserved and naturally occurring RNAs in eukaryotes.
