Causes and consequences of microsatellite instability in gastric carcinogenesis

This review summarizes the current knowledge on the molecular mechanisms underlying the acquisition of microsatellite instability (MSI) in gastric cancer (GC) as well as on the clinic, pathologic and molecular consequences of the MSI phenotype. Additionally, current therapeutic strategies for GC and their applicability in the MSI subset are also discussed.

Causas e consequências da instabilidade de microsatélites na carcinogénese gástrica

Este artigo de revisão sumariza o conhecimento atual acerca dos mecanismos moleculares subjacentes à aquisição da instabilidade de microsatélites (MSI) no cancro gástrico (GC), bem como nas consequências clínicas, patológicas e moleculares do fenótipo MSI. Também são discutidas as estratégias terapêuticas no GC, e o seu potencial benefício em pacientes com fenótipo MSI.

Genetic variants in the interleukin 1 alpha (IL1A) gene are associated with gastric cancer

This study is part of the EUR-GAST Project, established to elucidate the effects of Helicobacter pylori infection, genetic polymorphisms and environmental factors in gastric cancer etiology in European populations. The EUR-GAST Project is enclosed in a much larger European investigation (European Prospective Investigation into Cancer and Nutrition – EPIC) which is designed to investigate the relationships between diet, nutritional status, lifestyle and environmental factors and the incidence of cancer and other chronic diseases.

Researchers from IPATIMUP identified a molecule that can influence gastric cancer progression

Gastric cancer is one of the most prevalent and fatal in the world, especially due to its invasive nature, and the capacity to metastasize at distance, frequently without symptoms. E-cadherin is one of the most important structural molecules in the stomach, and its expression in the gastric epithelia suppresses cancer development. Carriers of mutations in the gene encoding E-cadherin have high probability of developing hereditary diffuse gastric cancer. Strategies aiming to prevent the loss of E-cadherin expression enclose high therapeutic potential for gastric cancer.
