Characterization of a Type 2 diabetes-associated islet-specific enhancer cluster in STARD10 by genome editing of EndoC-βH1 cells

Poster

Genome-wide association studies (GWAS) have identified more than 100 genetic loci associated with type 2 diabetes. The majority of these are located in the intergenic or intragenic regions suggesting that the implicated variants may alter chromatin conformation. This, in turn, is likely to influence the expression of nearby or more remotely located genes to alter beta cell function. At present, however, detailed molecular and functional analyses are still lacking for most of these variants. We recently analysed one of these loci and mapped five causal variants in an islet-specific enhancer cluster within the STARD10 gene locus. Here, we aimed to understand how these causal variants influence b-cell function by alteration of the chromatin structure of enhancer cluster

Psychiatric Risk Gene Cacna1c and Early Life Stress: Potential Gene-Environment interactions?

Poster

Early life stress (ELS) is highly associated with development of psychopathology
and mood disorders in adulthood. Genetic studies have identified variation in the gene calcium voltage-gated channel subunit alpha1C (CACNA1C) to increase risk for several psychiatric disorders. This poster assessed the expression of Cacna1c following prepubertal stress.

Regulatory T-Cells (Tregs) Within Bone Marrow-Derived Stem Cells (BMSCs) Actively Confer Immunomodulatory and Neuroprotective Effects Against Stroke

Poster

We found a distinct subpopulation of Tregs within BMSCs. Tregs and BMSCs in co-culture conferred neuroprotection that varied in a dose-dependent manner. Tregs minimized stem cell production of IL-6, a pro-inflammatory cytokine, and inhibited BMSC secretion of FGF-beta, a cytokine related to BMSC proliferation and differentiation. The ratio of Tregs found natively in BMSCs is optimally adapted to provide the maximum neuroprotective benefit of stem cell treatment after ischemic stroke.
