Project description:To evaluate differentially expressed genes and pathways in hippocampus between young (3-month-old, 3M) and aging (22-month-old, 22M) group. We then performed gene expression profiling analysis using data obtained from mRNA-seq in hippocampus of 3M and 22M group.

Project description:Aging is associated with a general decline of cognitive functions, and it is widely accepted that this decline results from changes in expression of proteins involved in regulation of synaptic plasticity. However, several lines of evidence has accumulated that impaired function of aged brain may be related to significant alterations in the energy metabolism. In the current study, we employed the label-free „Total protein approach” (TPA) method to focus on similarities and differences in energy metabolism proteomes of young (1 month-old) and aged (22 month-old) murine brains. We quantified over 7,000 proteins in each of three analyzed brain structures: hippocampus, cerebral cortex and cerebellum. To the best of our knowledge, this is the most extensive quantitative proteomic description of energy metabolism pathways during physiological aging of mice. The analysis demonstrates that aging does not affect significantly the abundance of total proteins in the studied brain structures, however, the levels of proteins constituting energy metabolism pathways differ significantly between young and aged mice.

Project description:Curcumin has been demonstrated to have many neuroprotective properties, including improvement of cognition in humans and neurogenesis in animals, yet the mechanism of such effects remains unclear. Here, we assessed behavioural performance and hippocampal cell proliferation in aged rats after 6- and 12-week curcumin-fortified diets. Curcumin enhanced non-spatial and spatial memory, as well as dentate gyrate cell proliferation as compared to control diet rats. We also investigated underlying mechanistic pathways that might link curcumin treatment to increased cognition and neurogenesis via microarray analysis of cortical and hippocampal mRNA transcription. We used microarrays to investigate the effects of short-term (6-week) and long-term (12-week) curcumin-supplemented diet on gene expression of hippocampus and cortex in aged rats. The hippocampus and cortex of every three rats from one group were pooled together, respectively and used for RNA extraction and hybridization on Affymetrix microarrays. To ensure the reliability of the data, we conducted hybridization experiments in duplicate microarrays from each RNA sample. The tissues examined by microarray are as follows: the hippocampus and cortex of 6-week curcumin-treated 15-month-old rats, the hippocampus and cortex of 6-week no curcumin-treated 15-month-old rats (control rats), the hippocampus and cortex of 12-week curcumin-treated 15-month-old rats, the hippocampus and cortex of 12-week no curcumin-treated 15-month-old rats (control rats).

Project description:Purpose: Transcriptome profiling (RNA-seq) to microarray to evaluate transcriptional changes in the heart of HD mouse models Methods: Heart mRNA profiles of 4-weeks-old wild-type (WT) and R6/2 transgenic; 15-weeks-old WT and R6/2 transgenic mice; 8-month-old WT and HdhQ150 knock-in mice; 22-month-old WT and HdhQ150 knock-in mice were generated by deep sequencing, in triplicate, using Illumina Hi-seq 2000. Conclusions: Our study showed that there is no major transcriptional deregulation in the heart of mouse models of HD.

Project description:We carried out a global survey of age-related changes in mRNA levels in the C57BL/6NIA mouse hippocampus and found a difference in the hippocampal gene expression profile between 2-month-old young mice and 15-month-old middle-aged mice correlated with an age-related cognitive deficit in hippocampal-based explicit memory formation. Middle-aged mice displayed a mild but specific deficit in spatial memory in the Morris water maze. Experiment Overall Design: No technical replicates; 14 biological replicates for 15-month-old mice, 9 biological replicates for 2-month-old mice. Whole hippocampus.

Project description:We used Affymetrix miRNA arrays to analyze the expression of miRNAs in the frontal cortex and hippocampus of 8-week-old C57BL/6J wt mice. We compared these microarray-based expression profiles to ones obtained by miRNA sequencing from the same brain regions of the same mouse strain. miRNA expression profiling of frontal cortex and hippocampus from C57BL/6J mice (N=3) was performed with Affymetrix miRNA array

Project description:To identify novel aging-related miRNAs, we initially established a physiological aging mouse model (20-month old male C57BL/6 mouse), compared with 2-month old male C57BL/6 mouse. Then, the Agilent miRNA microarray was performed to profile miRNA expression levels in kidney from 20-month old male C57BL/6 mouse (designated as Aging) and 2-month old male C57BL/6 mouse (designated as Young).
