Here, we report, in both these long-lived mice, that three up-regulated lead microRNAs, miR-470, miR-669b, and miR-681, are involved in posttranscriptional regulation of genes pertinent to growth hormone/IGF1 signaling. All three are most prominently localized in the hippocampus and correspond to reduced expression of key IGF1 signaling genes: IGF1, IGF1R, and PI3 kinase.

Thus, tetherin plays an important role in the innate cell-autonomous immune response. The aim of this study was to examine the antiviral activities of tetherin in vesicular stomatitis virus infections of murine neuronal cells.

This paper places the bio-genetic industry within the larger political economy framework of globalisation and privatisation, thus employing a framework that is often omitted from discussions on ARTs, but has direct and significant bearings on the ART industry in India. As markets for human organs, tissues and reproductive body parts experience unprecedented growth, the limits of what can or should be bought and sold continue to be pushed.

The size and health of the neuronal cell population determines cognitive robustness in mammals. A transgenic mouse model over-expressing Bcl-2 has been shown to rescue neurons from naturally occurring cell death (NOCD).
View Article and Find Full Text PDFAge-dependent loss of oxidative defense is well recognized in rodent models, although the control mechanism is still obscure; a few studies have shown how microRNAs, a non-coding RNA species, regulate the expression of their target genes at the post-transcriptional level. In the current study, miR-34a and miR-93 are observed to increase in middle- and old-age rat liver, compared to young rats; the up-regulation of these two miRNAs is determined by qPCR through a grind-and-find approach, and histochemical in situ hybridization. Three commonly used miRNA target prediction programs suggest four candidate targets of miR-34a and miR-93: Sp1, Nrf2 (Nfe2l2), Sirt1 and Mgst1; their expression is found to be reduced inversely to the up-regulation of the two miRNAs by Western blotting of protein extracts, as well as immunofluorescence staining of intact liver tissues.

The present investigation is an attempt to study the effect of solar treatment for disinfection of biomedical wastes with and without lime stabilization process. The laboratory experiments were conducted using box type solar disinfector with and without lime. The study involves the determination of parameters, such as COD, total solids, volatile solids, electrical conductivity, alkalinity and microbial colony count at different stages of disinfection.

The peptide aggregates formed at a concentration of 3 mM in the apolar solvent CDCl(3) were broken by the addition of 12% v/v of the more polar solvent DMSO-d(6). Successive N(i)H <--> N(i+1)H NOEs observed over the entire length of the sequence in this solvent mixture together with the observation of several characteristic medium-range NOEs support a major population of continuous helical conformations for Dpg-14.

Identifying functional factors secreted by stem cells, as well as their target cells, may advance our understanding of stem cells' multifaceted physiologic functions. Here, we report that mouse bone marrow stromal cell-derived neuroprogenitor cells (mMSC-NPC) provide a protective function by secreting a key factor, prosaposin (PSAP), capable of rescuing mature neurons from apoptotic death.

Although significant advances have been made demonstrating that this aging phenotype results primarily from an endocrine imbalance, the post-transcriptional regulation of gene expression and its impact on longevity remains to be explored. Towards this end, we present the first comprehensive study by microRNA (miRNA) microarray screening to identify dwarf-specific lead miRNAs, and investigate their roles as pivotal molecular regulators directing the long-lived phenotype.

Their role in aging mechanisms has been proposed in various model systems. In this report, the expression profiling of 462 human miRNAs in the reversible growth arrest state of quiescence, and irreversible states of replicative senescence and hydrogen peroxide-induced premature senescence, are compared to young replicating lung fibroblasts.
