The Hedgehog (Hh) signaling pathway is a developmentally conserved regulator of stem cell function. Several reports suggested that Hh signaling is an important regulator of hematopoietic stem cell (HSC) maintenance and differentiation. Here we test this hypothesis in vivo using both gain- and loss-o...

In this experiment, we want to assess the effect of a lentiviral miR-10a and miR-335 overexpression on the transcriptome of murine LSK (Lin-,Sca-1+,c-Kit+) cells. Primary LSK cells were transduced with lentiviral miRNA overexpression constructs (control: GFP overexpression) and sorted for transduced...

MicroRNAs influence hematopoietic differentiation, but little is known about their effects on the stem cell state. Here, we report that the microRNA processing enzyme Dicer is essential for stem cell persistence in vivo and a specific microRNA, miR-125a controls the size of the stem cell population ...

In response to osmolarity, Salmonella enterica serotype Typhi (S. Typhi) regulates genes required for Vi capsular antigen expression oppositely to those required for motility and invasion. Previous studies suggest that osmoregulation of motility, invasion and capsule expression is mediated through t...

Objective To establish whether whole-blood MicroRNA (miRNA) profiles differ between postural tachycardia syndrome (POTS) sufferers and control subjects, and to identify the miRNA that regulate plasma H2S. Study design: High-throughput sequencing was used to obtain whole-blood miRNA expression profi...
