Project description:Comparison of gene expression level by Illumina sequencing of rat skin from young and old animals. We identified differentially expressed genes and provide functional profiles, which give insights into the aging process of short-lived rodents.

Expression of miRNAs in breast tumor from very youn women (<36) and women above 65 years old

Project description:miRNA expression from breast tumor tissue obtained from two groups of breast cancer (BC) patients: one group formed by women younger than 36 years and the other group by women older than 65 years. We selected breast tumor tissue samples from 21 women under 36 years old and 12 women above 65 years old, without BRCA mutation and without metastases. We selected a pool of samples in which all the subtypes were representated, in young patients as well as in older patients, to avoid expression biass. We add three samples from breast tissue of cancer-free women to minimize the age-related expression biass. Our aim was to compare miRNA expression between young women and older women, considering normal tissue as a reference.

Quantitative analysis of skin proteomics in Chinese young and old populations by mass spectrometry

Project description:Aging is a normal physiological phenomenon of organisms. Skin aging is a specific manifestation of aging of local human organs. In this study, we used mass spectrometry to perform non-invasive analysis of the skin of 20 healthy young and elderly people in China. Quantitative proteomic analysis identified differentially expressed proteins.

miRNA expression data from sun-exposed and sun- protected skin of young (18-25 years) and old (>70 years) females

Project description:In this study we explored the effects of chronological and photoageing on the miRNome of human skin. To this end, miRNA expression was analysed in biopsies collected from sun-exposed (outer arm) and sun-protected (inner arm) skin from fair-skinned (phototype II/III) healthy female volunteers of two age groups: young, 18-25 years and aged, >70 years. Strict inclusion criteria were used for photoageing scoring and for chronological ageing. Microarray analysis revealed that chronological ageing had minor effect on the human skin miRNome. In contrast, photoageing had a robust impact on miRNAs, and a set of miRNAs differentially expressed between sun-protected and sun-exposed skin of the young and aged groups was identified. We have performed miRNome analysis (using microarray) on RNA isolated from sun-exposed and sun-protected skin of young and old females

Effects of resistance exercise on the transcriptome in MHC I and MHC IIa muscle fibers of young and old women

Project description:Global microarray (HG U133 Plus 2.0) was used for the first time to investigate the effects of resistance exercise on the transcriptome in slow-twitch myosin heavy chain (MHC) I and fast-twitch MHC IIa muscle fibers of young and old women. Vastus lateralis muscle biopsies were obtained pre and 4hrs post resistance exercise in the beginning (untrained state) and at the end (trained state) of a 12 wk progressive resistance training program.
