Wnt5a Suppresses β-catenin Signaling during Hair Follicle Regeneration
Hair follicles display periodic growth. Wnt signaling is a critical regulator for hair follicle regeneration. Previously, we reported that Wnt5a inhibits the telogen-to-anagen transition of hair follicles, but the mechanism by which this process occurs has not yet been reported. Here, we determined the expression patterns of Wnt signaling pathway molecules by quantitative reverse transcription ...
متن کاملWnt5a inhibits hypoxia-induced pulmonary arterial smooth muscle cell proliferation by downregulation of β-catenin.
Chronic hypoxia-induced pulmonary arterial hypertension (HPH) is closely associated with profound vascular remodeling, especially pulmonary arterial medial hypertrophy and muscularization due to hyperplasia of pulmonary artery smooth muscle cells (PASMCs). Aberrant Wnt signaling has been associated with lung diseases, but its role in pulmonary hypertension is unclear. This study evaluated the e...
متن کاملPurified Wnt5a Protein Activates or Inhibits β-Catenin–TCF Signaling Depending on Receptor Context
The Wnts comprise a large class of secreted proteins that control essential developmental processes such as embryonic patterning, cell growth, migration, and differentiation. In the most well-understood "canonical" Wnt signaling pathway, Wnt binding to Frizzled receptors induces beta-catenin protein stabilization and entry into the nucleus, where it complexes with T-cell factor/lymphoid enhance...
متن کاملNoncanonical Wnt5a enhances Wnt/β-catenin signaling during osteoblastogenesis
Wnt regulates bone formation through β-catenin-dependent canonical and -independent noncanonical signaling pathways. However, the cooperation that exists between the two signaling pathways during osteoblastogenesis remains to be elucidated. Here, we showed that the lack of Wnt5a in osteoblast-lineage cells impaired Wnt/β-catenin signaling due to the reduced expression of Lrp5 and Lrp6. Pretreat...
متن کاملGlycogen synthase kinase 3 β-dependent Snail degradation directs hepatocyte proliferation in normal liver regeneration.
Liver regeneration proceeds under the well-orchestrated control of multiple transcription factors that lead hepatocytes to reenter the cell cycle, proliferate, and renew quiescence. Here, we found an important role of the zinc-finger transcription factor Snail in liver regeneration. Snail was typically expressed in quiescent adult hepatocytes, but was rapidly degraded when the liver needed to r...
