Description
Calorie restriction (CR) enhances longevity and mitigates aging phenotypes in numerous species. Physiological responses to CR are cell-type specific and variable throughout the lifespan; however, the mosaic of molecular changes responsible CR benefits remain unclear, particularly in brain regions susceptible to deterioration throughout aging. Thus, we examined the influence of long-term CR on the CA1 hippocampal region, a key learning and memory brain area that is vulnerable to age-related pathologies, such as Alzheimer’s disease (AD). Through mRNA sequencing and NanoString nCounter analysis, we demonstrate that one year of CR feeding suppresses an age-dependent signature of 882 genes functionally associated with synaptic transmission-related pathways, including calcium signaling, long-term potentiation (LTP), and Creb signaling in wild-type mice. By comparing the influence of CR on hippocampal CA1 region transcriptional profiles at younger- (5 months) and older-adult (15 months) timepoints, we identify conserved upregulation of proteome quality control and calcium buffering genes, including heat shock 70 kDa proteins 1b and 5 (Hspa1b and Hspa5), protein disulfide isomerase family A members 4 and 6 (Pdia4 and Pdia6), and calreticulin (Calr). Expression levels of putative neuroprotective factors, klotho (Kl) and transthyretin (Ttr), are also elevated by CR throughout adulthood, although the global CR-specific expression profiles at young and older timepoints are highly divergent. At a previously unachieved resolution, our results demonstrate conserved activation of neuroprotective gene signatures and broad CR-suppression of age-dependent hippocampal CA1 region expression changes, indicating that CR functionally maintains a more youthful transcriptional state within hippocampal CA1 throughout aging. Overall design: Hippocampal CA1 region mRNA profiles of younger- (5 months) and older-adult (15 months) mice on calorie-restricted (CR) and normal (AD) diets were generated by deep sequencing using Illumina HiSeq 2500.

Description
Despite overwhelming data that cigarette smoking causes chronic obstructive pulmonary disease (COPD), only a minority of chronic smokers are affected, strongly suggesting that genetic factors modify susceptibility to this disease. We hypothesized that there are individual variations in the response to cigarette smoking, with variability among smokers in expression levels of protective / susceptibility genes. Affymetrix arrays and TaqMan PCR were used to assess the variability of gene expression in the small airway epithelium obtained by fiberoptic bronchoscopy of 18 normal non-smokers, 18 normal smokers and 18 smokers with COPD.

Description
Purpose: Mutations in several genetic loci lead to cardiac anomalies, with mutations in transcription factor NKX2-5 gene being one of the largest mutations known. Gestational hypoxia, such as seen in high-altitude pregnancy, has been known to affect cardiac development, and this paper aims to uncover information about the underlying mechanisms of this phenomena. Methods: Wild-type female mice were mated with Nkx2-5 mutant males, to produce offsprings. The pregnant females were then separated into two groups, one left in normal air and one breathing hypoxic, 14% oxygen, air from gestation day 10.5 to 12.5. Hearts were dissected from E12.5 embryos, subjected to RNA purification followed by RNA-seq. Wild-hypoxia and mutant-normoxia were compared to control wild-normoxia. Conclusions: The results of our study provide insights into a common molecular mechanism underlying non-genetic/epigenetic and genetic cardiac anomalies. Overall design: Embryonic mice were produced with either wild-type or mutant genomes, and some from each group were exposed to hypoxia during gestation, then physical analysis and RNA sequencing was done on the embryos.

Description
We collected airway epithelial brushings for microarray analysis from 42 asthmatics and two control groups 28 healthy subjects and 16 smokers. A subgroup of 32 asthmatics completed a randomized placebo-controlled trial of fluticasone propionate in which collection of brushings was repeated after 1 week of treatment.
