Project description:9-day-old Sertoli cells have a stronger proliferative activity compared with 21-day-old Sertoli cells. We used microarrays to detail the global programme of gene expression underlying cellularisation and identified distinct classes of up-regulated and down-regulated genes during this process.
Project description:time-course experiment with embryoid bodies of CGR8 mouse embryonic stem cells ; in the whole time-series RNA from 0 days old embryoid bodies were hybridized against RNA from 3 days and 10 days old embryoid bodies Keywords = embryoid bodies Keywords = mouse Keywords = time-course Keywords = oligonucleotide array Keywords: time-course
Project description:Examination of the difference in mRNA expression profile between mid-old fibroblasts co-cultured with mid-old fibroblasts and mid-old fibroblasts co-cultured with young fibroblasts
Project description:MicroRNAs have been reported to be involved in the regulation of cellular and organismal aging. However, little is known about the role of microRNAs in cardiac aging. We used microarrays to examine microRNA profiles in the hearts from young (8 week-old) and middle-aged (15 month-old) male mice.
Project description:Aging of the peripheral nervous system (PNS) is associated with structural and functional changes that lead to a reduction in regenerative capacity and the development of age-related peripheral neuropathy. Myelin is a central component in maintaining physiological peripheral nerve function, and differences in myelin maintenance, degradation, formation and clearance have been suggested to contribute to age-related PNS changes. In addition, recent proteomic studies have elucidated the complex composition of the total myelin proteome in health and its changes in neuropathy models. However, changes in the myelin proteome of peripheral nerves during ageing have not been investigated. Hence, the aim of this proteomics experiment was to define proteome changes in isolated myelin fractions during ageing, by investigating myelin proteome profiles from young (nerves from 2-3 month old mice) and old (nerves from 18 months old mice) nerves.
