Project description:The principal objective of this work was to investigate the somatic copy number changes that influence the risk of head and neck cancer occurrence and outcome from two large comprehensive case series in Europe and South America. A second objective was to investigate how these somatic changes interact with environmental and host risk factors such including HPV infection, alcohol and smoking.
Project description:Archaeological and archaeogenetic evidence points to the Pontic-Caspian steppe zone between the Caucasus and the Black Sea as the crucible from which the earliest steppe pastoralist societies arose and spread, ultimately influencing populations from Europe to Inner Asia. However, little is known about their economic foundations and the factors that may have contributed to their extensive mobility. Here we investigate the dental calculus proteomes of 45 individuals spanning the Neolithic to Greco-Roman periods in the Pontic-Caspian Steppe and neighboring South Caucasus, Oka-Volga-Don, and East Urals regions.
Project description:Here we present genome-wide high-coverage genotyping data on a panel of 75 human samples from Western Balkan region, Europe, that are used in addition to public data in studing the genetic variation of Southern Europe that was sequenced to the avwerage depth of 1X.

Project description:Gene and miRNA profiles from a unique Chinese/Caucasian trans-ethnic collection of breast cancer from Shanghai (China) and Milan (Italy) were compared using an unsupervised approach that identified similar clusters of correlated features in Chinese and Caucasian datasets. Partition of gene expression data using previously published gene signatures, such as the PAM50 intrinsic gene list and the extracellular matrix (ECM) genes, revealed Chinese and Caucasian subgroups with equivalent gene and miRNA expression profiles. A significant reduction of Luminal-A tumors was observed in the Chinese series. Tissue samples from 78 Chinese (Han Chinese) and 97 Italian (South Europe Caucasian) consecutive primary breast tumors were subjected to gene and miRNA profiling. Tissue specimens, initially collected respectively in the Chinese and Italian hospitals, were all stored, randomly processed and analyzed in identical experimental conditions in the Italian center to minimize pre-analytical, instrumental and computational variability, enabling direct comparison of gene and miRNA profiles from the two groups.

Project description:The current study aimed to address the hypothesis that programmed expression of key miRNAs in skeletal muscle mediates the development of insulin resistance, and consequently long-term health. We thus examined microRNA signatures in skeletal muscle of programmed insulin resistant rats offspring from high fat-fed dams vs control offspring from chow fed dams.
