TranscriptomicsThe SIRT1 activator SRT1720 extends lifespan and improves health of mice fed a standard diet
The prevention or delay of the onset of age-related diseases prolongs survival and improves quality of life while reducing the burden on the health care system. Activation of sirtuin 1 (SIRT1), an NAD+ deacetylase, improves metabolism and confers protection against physiological and cognitive distur...

TranscriptomicsNIA Neuroarray dehydration
The magnocellular neurons (MCNs) of the supraoptic nucleus (SON) and paraventricular nucleus (PVN) of the hypothalamus are the principal site of biosynthesis of prepropeptide precursor of the antidiuretic hormone vasopressin (VP). This precursor is processed during anterograde axonal transportation ...

TranscriptomicsChanges in mouse cognition and hippocampal gene expression observed in a mild physical- and blast-traumatic brain injury
Warfare has long been associated with traumatic brain injury (TBI) in militarized zones. Common forms of TBI can be caused by a physical insult to the head-brain or by the effects of a high velocity blast shock wave generated by the detonation of an explosive device. While both forms of trauma are d...

TranscriptomicsExendin-4, a glucagon-like peptide-1 receptor agonist prevents mTBI-induced changes in hippocampus gene expression and memory deficits in mice
Traumatic brain injury (TBI) is a global problem reaching near epidemic numbers that manifests clinically with cognitive problems that decades later may result in dementias like Alzheimer’s disease (AD). Presently, little can be done to prevent ensuing neurological dysfunctions by pharmacological me...

TranscriptomicsSRT2104 extends survival of male mice on a standard diet and preserves bone and muscle mass
Increased expression of SIRT1 extends the lifespan of lower organisms and delays the onset of age-related diseases in mammals. Here, we show that SRT2104, a synthetic small molecule activator of SIRT1, extends both mean and maximal lifespan of mice fed a standard diet. This is accompanied by improve...

TranscriptomicsSSH-PCR dehydrated supraoptic nucleus
The magnocellullar neurons (MCNs) of the supraoptic nucleus (SON) of the hypothalamus are the principle source of the neuropeptide hormone vasopressin (VP), which has a crucial role in osmoregulation. Physiological activation of the SON by dehydration results is a massive release of VP from stores i...

TranscriptomicsEuglycemic agent-mediated hypothalamic transcriptomic manipulation in the N171-82Q model of Huntington's disease is related to their physiological efficacy
Our aim was to find an effective treatment for the dysfunction in energy regulation and hypothalamic integrity occurring in many HuntingtonM-bM-^@M-^Ys disease (HD) patients and mouse models. HD is a neurodegenerative disease caused by an expanded CAG repeat and is characterized by mutant huntingtin...

TranscriptomicsToll-like receptor 2 (TLR2)-TLR9 crosstalk dictates IL-12 family cytokine production in microglia
Microglia are the resident mononuclear phagocytes of the CNS parenchyma and represent an initial line of defense against invading microorganisms. Microglia utilize Toll-like receptors (TLRs) for pathogen recognition and TLR2 specifically senses conserved motifs of gram-positive bacteria including li...

TranscriptomicsIdentification of transformation-related pathways in a breast epithelial cell model using a ribonomics approach.
Employing MCT-1 oncogene mediated transformation of immortalized breast epithelial MCF10A cells; we characterized the largely reciprocal association of these two RBPs with target mRNAs and their influence on protein expression vis-à-vis cellular transformation. Using a ribonomics approach, we ident...
