Project description:Gene expression profiling was carried out on peripheral blood mononuclear cell mRNA samples collected from 93 older adults participating in the Chicago Health Aging and Social Relations Study (CHASRS). The primary research question is whether gene expression differs in participants who are chronically lonely.

Project description:In this study participants were experimentally challenged with an infective dose of S. Typhi (1-5x10^3-4 cfu) and followed over at least 14 days. Every study participant was treated with antibiotics (ciprofloxacin, 500 mg twice daily, 14 days) on day 14 after challenge unless diagnosed with typhoid fever at which time treatment commenced immediately (ciprofloxacin, 500 mg twice daily, 14 days). For details about the study design please refer to Waddington et al. CID 2014 May;58(9):1230-40. Criteria for typhoid diagnosis were either microbiological (≥1 positive blood culture collected after day 5) and/or clinical (fever ≥38°C sustained for ≥12hrs). 3mL of venous blood was obtained at pre-challenge baselines, 24hrs prior typhoid diagnosis, day of diagnosis, 24hrs post-diagnosis and day 14 after challenge in those diagnosed with acute typhoid fever. In those who did not develop typhoid despite oral challenge samples were obtained at pre-challenge, day 7 and day 14 after challenge. The samples are labelled with one of the following accronyms: V1: Day 0, i.e. pre-challenge control. D7: day 7 after challenge. TD-24: 24hrs prior to typhoid diagnosis. TD: day of typhoid diagnosis. TD+24: 24hrs after typhoid diagnosis. D14: day 14 after challenge.

Project description:Although increased vascular stiffness is more prominent in aging males than females, and males are more prone to vascular disease with aging, no study has investigated the genes potentially responsible for gender differences in vascular aging. We tested the hypothesis that the transcriptional adaptation to aging differs in males and females using a monkey model, which is not only physiologically and phylogenetically closer to humans than the more commonly studied rodent models, but also is not afflicted with the most common forms of vascular disease that accompany the aging process in humans, e.g., atherosclerosis, hypertension, and diabetes. Gene expressions of monkey aorta from four groups (YF, OF, YM, OM) were detected to find out the molecular mechanism of aorta stiffness. Experiment Overall Design: Four groups were used in this experiment. 6 samples per group.The transcriptional profile of the aorta was compared by high-density microarrays between young and old males or females. About 600 genes were expressed differentially when comparing old versus young animals. Analysis of the different groups was further performed by gene ontology.We also analyzed whether the transcriptional regulation described above might correspond to specific transcription factors

Project description:The aim of this investigation was to develop a global view of muscle transcriptional differences between older men and women and with aging for each sex. Muscle biopsies were obtained from the biceps brachii of young (age 19~28yrs) and older (age 65~76 yrs) men (7 young, 4 older) and women (7 young, 4 older). Total RNA was extracted and gene expression profiling was performed using the Affymetrix Human Genome U133 Plus 2 chip.

Project description:Aging is associated with increased monocyte production and altered monocyte function. Classical monocytes are heterogenous and a shift in their subset composition may underlie some of their apparent functional changes during aging. We have previously shown that mouse granulocyte-monocyte progenitors (GMPs) produce “neutrophil-like” monocytes (NeuMo), whereas monocyte-dendritic cell progenitors (MDPs) produce monocyte-derived dendritic cell (moDC)-producing monocytes (DCMo). Here, we demonstrate that classical monocytes from the bone marrow of old male and female mice have higher expression of DCMo signature genes (H2-Aa, H2-Ab1, H2-Eb1, Cd74), and that more classical monocytes express MHCII and CD74 protein. Moreover, we show that bone marrow MDPs and classical monocytes from old mice yield more moDC. We also demonstrate higher expression of Aw112010 in old monocytes and that Aw112010 lncRNA activity regulates MHCII induction in macrophages, which suggests that elevated Aw112010 levels may underlie increased MHCII expression during monocyte aging. Finally, we show that classical monocyte expression of MHCII is also elevated during healthy aging in humans. Thus, aging-associated changes in monocyte production may underlie altered monocyte function and have implications for aging-associated disorders.

Project description:Gene expression profiling was carried out on peripheral blood mononuclear cell mRNA samples collected from renal cell carcinoma patients. The primary research question is whether gene expression differs as a function of patient's level of depression as measured by CESD score > 16.

Project description:Spinal motor neurons have been implicated in the loss of motor function that occurs with advancing age. However, the cellular and molecular mechanisms that impair the function of these neurons during aging remain unknown. Here, we show that motor neurons do not die in old female and male mice, rhesus monkeys, and humans. Instead, these neurons selectively shed excitatory synaptic inputs throughout the soma and dendritic arbor during aging. By examining the translatome , we also show that aging alters the molecular composition of motor neurons in both male and female mice. Aging motor neurons present with changes in genes and molecular pathways with roles in glia-mediated synaptic pruning, and inflammation. They also exhibit changes in pathways with roles in axonal regeneration caused by axotomy and Amyotrophic Lateral Sclerosis (ALS). Thus, we have identified cellular and molecular mechanisms altered in aged motor neurons that could serve as therapeutic targets to preserve motor function during aging.
