Abnormal accumulation of beta-catenin is considered to be a strong driving force in hepatocellular carcinogenesis; however, the mechanism of beta-catenin accumulation in tumours is unclear. Here, it was demonstrated that hepatitis B virus X protein (HBx) differentially regulates the level of beta-catenin through two ubiquitin-dependent proteasome pathways(More)
Glioblastoma multiforme (GBM) is the most aggressive malignant brain tumor. Since differentiation can attenuate or halt the growth of tumor cells, an image-based phenotypic screening was performed to find out drugs inducing morphological differentiation of GBMs. Bexarotene, a selective retinoid X receptor agonist, showed strong inhibition of neurospheroidal(More)
