TEAD1 is crucial for developmental myelination, Remak bundles, and functional regeneration of peripheral nerves.

Previously we showed that the hippo pathway transcriptional effectors, YAP and TAZ, are essential for (SCs) to develop, maintain and regenerate myelin . Although TEAD1 has been implicated as a partner transcription factor, the mechanisms by which it mediates YAP/TAZ regulation of SC myelination are unclear. Here, using conditional and inducible knockout mice, we show that TEAD1 is crucial for SCs to develop and regenerate myelin.

Co-targeting B-RAF and PTEN Enables Sensory Axons to Regenerate Across and Beyond the Spinal Cord Injury.

Primary sensory axons in adult mammals fail to regenerate after spinal cord injury (SCI), in part due to insufficient intrinsic growth potential. Robustly boosting their growth potential continues to be a challenge. Previously, we showed that constitutive activation of B-RAF (rapidly accelerated fibrosarcoma kinase) markedly promotes axon regeneration after dorsal root and optic nerve injuries.

Co-targeting myelin inhibitors and CSPGs markedly enhances regeneration of GDNF-stimulated, but not conditioning-lesioned, sensory axons into the spinal cord.

A major barrier to intraspinal regeneration after dorsal root (DR) injury is the DR entry zone (DREZ), the CNS/PNS interface. DR axons stop regenerating at the DREZ, even if regenerative capacity is increased by a nerve conditioning lesion. This potent blockade has long been attributed to myelin-associated inhibitors and (CSPGs), but incomplete lesions and conflicting reports have prevented conclusive agreement.

MELK and EZH2 Cooperate to Regulate Medulloblastoma Cancer Stem-like Cell Proliferation and Differentiation.

Medulloblastoma is the most common malignant brain tumor in children. Although accumulated research has suggested that cancer stem-like cells play a key role in medulloblastoma tumorigenesis, the specific molecular mechanism regarding proliferation remains elusive. Here, we reported more abundant expression of maternal embryonic leucine-zipper kinase (MELK) and enhancer of zeste homolog 2 (EZH2) in medulloblastoma stem-like cells than in neural stem cells and the interaction between the two proteins could mediate the self-renewal of sonic hedgehog subtype medulloblastoma.
