Cryptotanshinone inhibits constitutive signal transducer and activator of transcription 3 function through blocking the dimerization in DU145 prostate cancer cells.
It is the first report that cryptotanshinone has antitumor activity through the inhibition of STAT3, a potent anticancer agent targeting the activation STAT3 protein.
KRIBB11 Inhibits HSP70 Synthesis through Inhibition of Heat Shock Factor 1 Function by Impairing the Recruitment of Positive Transcription Elongation Factor b to the hsp70 Promoter*
Chromatin immunoprecipitation analysis showed that KRIBB11 inhibited HSF1-dependent recruitment of p-TEFb (positive transcription elongation factor b) to the hsp70 promoter, which strengthens the rationale for targeting HSF 1 in cancer therapy.
Blocking Tumor Cell Migration and Invasion with Biphenyl Isoxazole Derivative KRIBB3, a Synthetic Molecule That Inhibits Hsp27 Phosphorylation*
Overall, the results demonstrate that KRIBB3 inhibits tumor cell migration and invasion by blocking protein kinase C-dependent phosphorylation of Hsp27 through its direct binding to HSP27.
Phosphatase of regenerating liver‐3 promotes migration and invasion by upregulating matrix metalloproteinases‐7 in human colorectal cancer cells
It was found that PRL‐3 induced MMP‐7 through oncogenic pathways including PI3K/AKT and ERK and that there is a relationship between the expression of PRL-3 and MMP-7 in human tumor cell lines.
Computational determination of hERG-related cardiotoxicity of drug candidates
The neural network model can predict hERG-related cardiotoxicity of chemical compounds with a high accuracy and can be applied to virtual high-throughput screening for drug candidates that do not cause cardiot toxicity.
