Childhood-onset primary osteoporosis is manifested as reduced bone mineral density, peripheral fractures and/or vertebral compression fractures. Until now, only mutations in LRP5 have been shown to cause the disorder. Candidate gene analyses were performed on 15 patients with primary osteoporosis and 80 healthy controls using CSGE and sequencing. The genes studied included DKK1, DKK2, WNT3A, WN...
AurkA overexpression was previously found in breast cancer and associated to its ability in controlling chromosome segregation during mitosis, however whether it may affect breast cancer cells, endorsed with stem properties (BCICs), is still unclear. Surprisingly, a strong correlation between AurkA expression and β-catenin localization in breast cancer tissues suggested a link between AurkA and...
In the development of the vertebrate body plan, Wnt3a is thought to promote the formation of paraxial mesodermal progenitors (PMPs) of the trunk region while suppressing neural specification. Recent lineage-tracing experiments have demonstrated that these trunk neural progenitors and PMPs derive from a common multipotent progenitor called the neuromesodermal progenitor (NMP). NMPs are known to ...
Sonic hedgehog (Shh) signaling plays an important role in many human cancers and cancer stem cells. Here we investigate the activity and functional role of Shh signaling in chronic myeloid leukemia (CML) and leukemia progenitor cells. Differential activation of Shh signaling was found in about 50% CML chronic phase samples, about 70% of CML accelerated phase samples, and >80% CML blast crisis p...
BACKGROUND There are changes in the skeletal muscle of patients with chronic heart failure (CHF), such as volume reduction and fiber type shift toward fatigable type IIb fiber. Forkhead box O (FoxO) signaling plays a critical role in the development of skeletal myopathy in CHF, and functional interaction between FoxO and the Wnt signal mediator β-catenin was previously demonstrated. We have rec...
About 20% hepatocellular carcinomas (HCCs) display wild-type β-catenin, enhanced Wnt signaling, hepatocyte dedifferentiation and bad outcome, suggesting a specific impact of Wnt signals on HCC stem/progenitor cells. To study Wnt-specific molecular pathways, cell fates and clinical outcome, we fine-tuned Wnt/β-catenin signaling in liver progenitor cells, using the prototypical Wnt ligand Wnt3a. ...
The complexity of canonical Wnt signaling comes not only from the numerous components but also from multiple post-translational modifications. Protein phosphorylation is one of the most common modifications that propagates signals from extracellular stimuli to downstream effectors. To investigate the global phosphorylation regulation and uncover novel phosphoproteins at the early stages of cano...
Introduction: Major peripheral nerve injuries lead to significant functional deficits. Although the general belief is that the regenerative capacity of the PNS when compared to the CNS is much more robust after nerve insult, this does not translate in the clinical setting. A reason for this phenomenon may be explained by end-organ atrophy. We recently showed that preservation of the motor endpl...
Neural stem cells (NSCs) show great promise in drug discovery and clinical application. Yet few efforts have been made to optimize biocompatible materials for such be expanded used conditions. We previously demonstrated that NSCs are readily cultured on substrates of certain recombinant spider silk protein without addition animal- or human-derived components. The question remains however whethe...
