Project description:Very little is known about the effects of aging on tissues such as the lung, and the resulting effects of immune cells within the tissue. We performed a microarray on total cells from young and aged mice to determine signaling pathways that are altered with aging.
Project description:Aging animals undergo a variety of changes in molecular processes. Among these, the cellular circadian clock has been shown to change as animals age. Moreover, there is evidence that also core circadian clock proteins could influence the ageing behavior of vertebrates. To investigate the interplay between aging and the circadian clock, we studied circadian mRNA expression in skeletal muscles from young (8 weeks) and aged (80 weeks) mice. In order to detect differences in circadian patterns, we used microarray-based transcriptome-wide time series of mRNA expression, containing 16 independent measurements for both young and aged animals. Each individual time point consists of total RNA from hind limb skeletal muscles from 3 different animals.
Project description:Analysis of function of CD11c+ cells from middle-aged and young mice at gene level. This experiment provided insight into the different genes that plays roles in inflammation, immune response and mainly arachidonic acid cascade that are differentiall expressed in CD11c+ cells from middle aged and young mice. Total RNA was isolated from pulmonary CD11c cells (separated using magnetic beads) from middle-aged and young mice

Each individual time point consists of total RNA from hind limb skeletal muscles from 3 different animals. Young and aged mice where entrained to 12 hr/12 hr light-dark conditions. From these mice, hind limb skeletal muscles were extracted at different times of day, in order to measure circadian mRNA expression patterns.
Project description:T cells change substantially with age and are involved in atherosclerosis. Aging is the strongest clinical risk factor for atherosclerosis so we profiled T cells in young and aged mice prior to atherosclerosis (healthy) and in young and aged atherosclerotic mice (diseased).
Project description:We report the gene expression changes in mobilized peripheral blood in aged, young, and aged/young samples cocultured in transwell. Restored samples refer to aged MPB co-cultured with young MPB in the transwell culture
Project description:Purpose of this experiment was to study the host-transcriptional response to MA-15, MA-15epsilon, and MA-15-gamma in both young and aged mice to further understand the differences between response within each age group, and the age-related differences in response to each virus. Young (8 weeks old) and aged (1 year old) female BALB/c mice were intranasally infected with 10^5 PFU of either MA15, MA15 gamma, MA15 epsilon, or phosphate buffer solution (PBS; mock-infection). Lungs from aged mice were harvested at 12, 24, and 48 hours post-infection. Lungs from young mice were harvested at 12, 24, 48, and 96 hours post-infection. For the aged mice, 3 biological replicates were collected for microarray analysis at each time point from the infected groups. 3 mocks at 12h, 2 mocks each at 24 and 48h time points.For the young mice, 4 biological replicates were collected for microarray analysis at each time point from the infected groups.
