DNA Source Selection for Downstream Applications Based on DNA Quality Indicators Analysis.

High-quality human DNA samples and associated information of individuals are necessary for biomedical research. Biobanks act as a support infrastructure for the scientific community by providing a large number of high-quality biological samples for specific downstream applications. For this purpose, biobank methods for sample preparation must ensure the usefulness and long-term functionality of the products obtained.

The Nodal inhibitor Lefty is negatively modulated by the microRNA miR-302 in human embryonic stem cells.

MicroRNAs (miRNAs) have been shown to be important in early development and maintenance of human embryonic stem cells (hESCs). The miRNA miR-302-367 is specifically expressed in hESCs, and its expression decays on differentiation. We previously identified the structure of the gene coding for the human miR-302-367 cluster and characterized its promoter.

The miR-302-367 cluster as a potential stemness regulator in ESCs.

Increasing experimental evidence suggests an important role of miRNAs in embryonic stem cell (ESC) biology. The miR-302-367 cluster is exclusively expressed at high levels in ESCs but not in either somatic stem cells or adult/embryonic differentiated cells. The human miR-302-367 gene structure has been recently described and its promoter has been identified, characterized and functionally validated in human stem cells.

Embryonic stem cell-specific miR302-367 cluster: human gene structure and functional characterization of its core promoter.

MicroRNAs (miRNAs) play a central role in the regulation of multiple biological processes including the maintenance of stem cell self-renewal and pluripotency. Recently, the miRNA cluster miR302-367 was shown to be differentially expressed in embryonic stem cells (ESCs). Unfortunately, very little is known about the genomic structure of miRNA-encoding genes and their transcriptional units.
