GCAT|genomes for life: A cohort of the genomes of catalonia, the microbiome, and DNA methylation
alterations in gastrointestinal cancer
T
he cancer genome accumulates numerous genetic and epigenetic alterations. Microbiomes are now considered an
essential component of health and disease. Bacteria can associate and have an impact in the epigenetic alterations of
gastrointestinal cancer (GC). In one example, we reported that gastric cancer exhibited abnormally low DNA methylation
compared with matching normal tissue or the normal tissue from first-degree relatives. Our results showed the link between an
epigenetic alteration (DNA hypomethylation) and H. pylori infection. In another example, we described how other epigenetic
abnormalities (DNA hypermethylation), may be aberrantly introduced in the human genome by
Mycoplasma hyorhinis
methyl
transferases. Our findings unveiled a novel link between the microbiome and human epigenetics with special relevance to
cancer epigenetics. A long-term prospective cohort study called Genomes for Life (GCAT) will be useful to further explore the
association between GCs, their epigenetic alterations, and the microbiome and other environmental factors. The GCAT project
was designed to explore the role of epidemiologic, genomic, and epigenomic factors in the development of cancer and other
chronic diseases in Catalonia, Spain. GCAT will have recruited 22.000 participants at the end of 2017. Participants complete a
detailed epidemiological questionnaire and undergo anthropometry measurements, and plasma, serum, and white blood cells
are collected. The GCAT study has access to the Electronic Health Records (EHR) of the Catalan Public Health Care System.
Participants will be followed at least 20 years after recruitment. Several approaches will be used to investigate the association of
epidemiologic and genetic risk factors with various cancers and chronic diseases.
