Wnt Signaling Regulates the Function of MyoD and Myogenin

MyoD and Myogenin

Canonical Wnt signaling negatively regulates platelet function.

Wnts regulate important intracellular signaling events, and dysregulation of the Wnt pathway has been linked to human disease. Here, we uncover numerous Wnt canonical effectors in human platelets where Wnts, their receptors, and downstream signaling components have not been previously described. We demonstrate that the Wnt3a ligand inhibits platelet adhesion, activation, dense granule secretion...

Hedgehog Signaling Regulates MyoD Expression and Activity*

The inhibition of MyoD expression is important for obtaining muscle progenitors that can replenish the satellite cell niche during muscle repair. Progenitors could be derived from either embryonic stem cells or satellite cells. Hedgehog (Hh) signaling is important for MyoD expression during embryogenesis and adult muscle regeneration. To date, the mechanistic understanding of MyoD regulation by...

Kindlin 2 Regulates Myogenic Related Factor Myogenin via a Canonical Wnt Signaling in Myogenic Differentiation

Kindlin 2, as an integrin-associated protein, is required for myocyte elongation and fusion. However, the association of Kindlin 2 with muscle differentiation-related signaling pathways is unknown. Here, we identified a mechanism that Kindlin 2 regulates myogenic regulatory factors myogenin via a canonical Wnt/β-catenin signaling. We found that knockdown of Kindlin 2 leads to the abolishment of...

Interaction of viral oncogenic proteins with the Wnt signaling pathway

It is estimated that up to 20% of all types of human cancers worldwide are attributed to viruses. The genome of oncogenic viruses carries genes that have protein products that act as oncoproteins in cell proliferation and transformation. The modulation of cell cycle control mechanisms, cellular regulatory and signaling pathways by oncogenic viruses, plays an important role in viral carcinogenes...
