Hedgehog pathway inhibition and the race against tumor evolution
Dependence of basal cell carcinomas and medulloblastomas on the Hedgehog pathway provides an opportunity for targeted or "personalized" therapy. The recent effectiveness and FDA approval of the first Smoothened inhibitors validates this class of agents, but has revealed drug-resistant tumor variants that bypass Smoothened inhibition. Here, we summarize the effectiveness of Hedgehog pathway inhi...
متن کاملHedgehog Pathway Inhibition
The hedgehog (Hh) signaling pathway is aberrantly activated in a majority of basal cell carcinomas (BCC). Vismodegib and sonidegib are targeted inhibitors of Smoothened (SMO). Both drugs are approved for use in locally advanced BCC (laBCC), with vismodegib also approved for metastatic BCC (mBCC).
متن کاملMedulloblastoma growth inhibition by hedgehog pathway blockade.
Constitutive Hedgehog (Hh) pathway activity is associated with initiation of neoplasia, but its role in the continued growth of established tumors is unclear. Here, we investigate the therapeutic efficacy of the Hh pathway antagonist cyclopamine in preclinical models of medulloblastoma, the most common malignant brain tumor in children. Cyclopamine treatment of murine medulloblastoma cells bloc...
متن کاملInhibition of the hedgehog pathway targets the tumor-associated stroma in pancreatic cancer.
PURPOSE The Hedgehog (Hh) pathway has emerged as an important pathway in multiple tumor types and is thought to be dependent on a paracrine signaling mechanism. The purpose of this study was to determine the role of pancreatic cancer-associated fibroblasts (human pancreatic stellate cells, HPSCs) in Hh signaling. In addition, we evaluated the efficacy of a novel Hh antagonist, AZD8542, on tumor...
متن کاملThe role of the desert hedgehog signaling pathway during degeneration and regeneration of peripheral nerves
The desert hedgehog (Dhh) signaling pathway is involved in the development of peripheral nerves (PNs). Dhh-null mice show abnormal neuronal development and perineurial barrier function. As it was previously shown that dhh is mainly expressed in developmental nerves and Sonic hedgehog protein (dhh homologous) has therapeutic effects in neuronal survival, we attempted to investigate the possible ...
