Gene expression profiling is an exceedingly important tool in functional genomics research and in drug discovery. The general trend in the field is towards higher throughput of less complex samples. Nowadays studies are appearing where expression of tens of genes is measured in hundreds of individual single cells, to be able to characterize cell subtypes and its roles. To identify subpopulations of astrocytes, to define them in molecular terms, and to determine the biological progress of astrocyte maturation on single cell level we developed and optimized protocol for high-throughput gene expression profiling using qPCR together with a system of quality control: ValidPrimeTM - control for genomic DNA background, Interplate calibrator - tool, which is used to compensate for inter-run variation in qPCR and Universal Spike (RNA/DNA), which can be used to detect presence of inhibition in samples of any living species or monitor losses and yield of isolation, or check the integrity of mRNA during sample processing, storage and transporation.
Inhibition of The Auto-inflammation Suppressor Protein ISG15 Triggers Preeclampsia by Blocking Trophoblast Migration and InvasionPoster
In summary, ISG15 expression levels are crucial for trophoblast morphology and function (migration/invasion). By blocking trophoblast invasion, reduced ISG15 levels could contribute to impaired spiral artery transformation that reduces utero-placental blood flow in preeclampsia. Thus, agents inducing ISG15 expression are likely to be therapeutic in preeclampsia.
An Emerging Phenotype of Partial RAG 1/2 Deficiency Among Young Children with Autoimmunity and Viral InfectionsPoster
We describe the natural history of a cohort of 12 patients with confirmed partial RAG1/2 mutations and autoimmunity at a young age. We were seeking the link between viral infections and autoimmunity and tested candidate biomarkers that may reflect the underlying RAG1/2 protein deficiency.READ MORE
