Serine-arginine-rich (SR) proteins play a key role in alternative pre-mRNA splicing in eukaryotes. We recently showed that a large SR protein called Son has unique repeat motifs that are essential for maintaining the subnuclear organization of pre-mRNA processing factors in nuclear speckles. Motif analysis of Son highlights putative RNA interaction domains that suggest a direct role for Son in pre-mRNA splicing. Here, we used in situ approaches to show that Son localizes to a reporter minigene transcription site, and that RNAi-mediated Son depletion causes exon skipping on reporter transcripts at this transcription site. A genome-wide exon microarray analysis was performed …

The number of laboratories using zebrafish as an experimental animal model has risen tremendously over the past two decades (Craig et al., 2006). As a result, the number of zebrafish facilities around the world has dramatically increased to meet the elevated demand for proper animal care and maintenance. In order to meet this demand, aquaculture facilities must employ husbandry protocols designed to produce a constant supply of healthy, viable eggs. Surprisingly, many husbandry strategies, particularly feeding protocols, are frequently passed down from members of one lab to another in a colloquial fashion without rigorous experimental validation. An ideal diet should …

Wound healing is a complex, multi-step process that can be summarized into three stages, namely hemostasis and inflammation, proliferation, and finally tissue remodeling. Battlefield wound healing demands rapid hemostasis using clotting or cauterizing agents to immediately limit blood loss, but this occurs at the expense of proper tissue repair beyond hemostasis. Layered silicate clays such as kaolin and montmorillonite (MMT) have been previously shown to induce blood clotting due to their ability to form charged interactions with clotting factors. The charge characteristics of sodium MMT (Na-MMT) also enable functionalization with active biomolecules. Herein we first functionalize three types of alumoinosilicate …

The human-associated microbiota has been the focus of much current research, with the microbiota inhabiting the gastrointestinal tract of particular interest. These organisms play many roles in human health and well-being. However, shifts in the composition of the intestinal microbiota have been associated with diseases such as irritable bowel syndrome, inflammatory bowel disease, and colon cancer. Several recent studies have reported on the distal gut microbiota composition of healthy adults and those with IBS, while there is a lack of studies devoted to adolescents. This study utilized a custom-designed Affymetrix Microbiota Array capable of detecting 775 phylo-species of intestinal bacteria …

We describe a methodology that combines urinary metabolomics with a tissue-specific stressor administration to enhance assessment of tissue function. Kidney function in rats was mildly compromised with a sub-acute dose of D-serine and stressed with furosemide. NMR-based metabolomics analyses showed no detectable effects due to D-serine alone; but furosemide or D-serine + furosemide groups, classified separately from each other, and from control. Furosemide alone caused a ca. 2-fold increase in glucose, lactate, choline, and a 30% decrease in TCA intermediates (p≤0.05). D-serine suppressed these effects and produced a 1.7-fold increase in a p-phenolic acid-derivative of tyrosine (PAdY) relative to control …

Peroxisome proliferator-activated receptors (PPAR) and liver X receptors (LXR) are known to play important roles in fatty acid metabolism, interact with each other, and function as heterodimeric partners. Although previous studies indicate that PPARα is activated by long chain fatty acyl-CoA thioesters (LCFA-CoA) and polyunsaturated fatty acids, little is known about the effects of these ligands on the function or interaction of PPARα and LXRα. In this study, hPPARα and hLXRα were shown to directly interact by circular dichroism, fluorescent binding assays, and co-immunoprecipitation. Further experiments suggested that although fatty acids resulted in small structural changes, they significantly altered binding …
