Mitogen activated protein kinase (MAPK) cascades are thought to mediate diverse biological functions such as cell growth, differentiation and migration. Activated MAPK may affect microtubule (MT) which is essential for cellular polarity, differentiation and motility. Data in this study show that JWA, a newly identified novel microtubule-associated protein(More)
Oxidative stress has been implicated as one of the primary mechanisms inducing DNA damage and believed to mediate aging and progression of numerous age-related diseases, including cancer. JWA, a gene previously described to mediate differentiation of leukemic cells, is also involved in cellular responses to environmental exposures linked to heat shock and(More)
Multidrug resistance (MDR) to anticancer drugs is a major obstacle to successful chemotherapy in the treatment of cancers. Identification of natural compounds capable of circumventing MDR with minimal adverse side effects is an attractive goal. Here, we found that H6, a gypenoside aglycon from Gynostemma pentaphyllum, displayed potent anti-MDR activity.(More)
UNLABELLED Activation of β-catenin, the central effector of the canonical wingless-type (Wnt) pathway, has been implicated in hepatocellular carcinoma (HCC). However, the transcription regulation mechanism of the β-catenin gene in HCC remains unknown. Here we report that human zinc finger protein 191 (ZNF191) is a potential regulator of β-catenin(More)
Cultured mycelium Cordyceps sinensis (CMCS) is a Chinese herbal medicine, which is widely used for a variety of diseases including liver injury in clinic. The current study aims to investigate the protective effects of CMCS against liver fibrosis and to exploit its active antifibrotic substances in vivo and in vitro. For evaluating the antifibrotic effect(More)
The discovery and optimization of a series of 2-N-aryl-substituted benzenesulfonamidoacetamides as novel tubulin polymerization inhibitors are described. Pharmacophore exploration of hit compound AH-487 identified the optimal structure of N-heteroaryl-2-(4-methoxy-N-(3-(trifluoromethyl)phenyl)phenylsulfonamido)acetamide as a potent antimitotic agent.(More)
Multi-drug resistance (MDR) to anticancer drugs remains a major impediment in cancer therapy. A major goal for scientists is to identify more effective compounds that are able to circumvent MDR and simultaneously have minimal adverse side effects. Here, we reported that Pyramidatine (Z88), a cinnamic acid-derived bisamide compound isolated from the leaves(More)
