Advanced Center forChronicDiseases General Aim: Toprovide a frameworkfortheunderstanding and prevention of thetwomainchronicdiseasesaffectingtheChileanpopulation. In associationwith a network of internationalcollaborators, ACCDiS aspires tobecoming a referencecenter in LatinAmericaforresearch and advanced training in chronicdiseases (CDs). • SpecificAims: • Todevelop a multidisciplinaryresearchinitiativethatwillpermitanalyzingthe natural history of cardiovascular diseasesand cancer in theChileanpopulation. • Toestablishspecificresearchlines in thearea of cancer and cardiovascular diseasescoveringbasic, clinical and epidemiologicalaspects and theirpublichealthconsequences. • To set up novel commonfacilitiesthatprovidestate of the art supportforthebasic, clinical and epidemiologicalresearch and training units. • Totrainadvanced human resources in CDs in collaborationwithourinternationalpartners. • Tocommunicatetothegeneral publicCD-relatedinformationand educate in diseaseprevention.

Collaborative Research Maule Cohort (MAUCO)Rolando de la Cruz, Claudia Bambs, Pablo Toro and the six ACCDiS groups The epidemic of chronic diseases is associated with lifestyle and environmental changes and interactions with the genetic background of the population, which create unique disease profiles. The county of Molina (Maule region) with a high burden of chronic diseases is an ideal setting for population-based studies designed to identify key factors involved in disease development. Aims: To measure at baseline and follow-up on: • Risk factors: a) Socioeconomic and occupational; b) Psycho-social and lifestyle; c) Environmental; d) Chronic infections and inflammation; e) Genetic and ethnic. • Health biomarkers and disease-related events: a) Cardiovascular and metabolic outcomes; b) Cancer; c) Nutrition; d) Aging; e) Respiratory diseases. Chronic diseases share common risk factors and most of them are preventable Molina Methods: Population-based prospective cohort of 10,000 subjects aged >45 yrs, residents of Molina county. Collect biological samples and conduct an epidemiological survey (Biobank and Databank).

Line 3: Inflammation in Angiogenesis, CellMigration, Metastasis Andrew Quest (PI), Lisette Leyton (AI), Carmen Romero (AI) • Pro-inflammatory stimuli (Prostaglandin E2, Helicobacter pylori) promote survivin dependent tumor angiogenesis and caveolin1-enhanced metastasis • Survivinexpression in tumor cells favors angiogenesis by promoting β-catenin/Tcf-Lef-dependent transcription of VEGF via a PI3K/Akt-mediated pathway • Pro-inflammatory stimuli disrupt E-cadherin/caveolin-1 surface complexes and promote β-catenin/Tcf-Lef- and HIF-1α-dependent transcription of survivin, cox2 and vegf • Pro-inflammatory stimuli activate NADPH oxidases and Src-family kinases, liberate caveolin-1 from E-cadherin/caveolin-1 surface complexes and promote migration/invasion via caveolin-1 enhanced tyrosine-14 phosphorylation and Rac1 activation Aim 1 Cell culture Chick CAM assay Aim 2 Murine tumor model Aim 3 Molina MAUCO In the cohort, look for microRNAs specific for caveolin-1 and E-cadherin (early phase) and caveolin-1 exosomes(metastasis marker)
