We investigated the role of the CXCR4 chemokine receptor in development of the mouse hippocampus. CXCR4 mRNA is expressed at sites of neuronal and progenitor cell migration in the hippocampus at late embryonic and early postnatal ages. mRNA for stromal cell-derived factor 1 (SDF-1), the only known ligand for the CXCR4 receptor, is expressed close to these(More)
In this study, we examined chemokine receptor expression and function in rat cerebellar neurons. Calcium imaging experiments demonstrated that a wide variety of chemokines elicited [Ca(2+)](i) transients in acutely isolated and cultured cerebellar Purkinje and granule neurons. In many cases, these chemokine responses were pertussis toxin (PTX) insensitive.(More)
Hedgehog signaling pathway plays a critical role in the initiation and development of pancreatic ductal adenocarcinoma (PDA) and represents an attractive target for PDA treatment. Lithium, a clinical mood stabilizer for mental disorders, potently inhibits the activity of glycogen synthase kinase 3β (GSK3β) that promotes the ubiquitin-dependent proteasome(More)
Diketoreductase catalyzes a two-step bioreduction on a dicarbonyl substrate through a novel dual catalysis mode, in which random hydride attack simultaneously forms two mono-carbonyl intermediates, and subsequently distinct catalytic sites are responsible for the reductions of respective carbonyl group of the intermediates to yield the final dihydroxy(More)
Tumor metastasis is the most common cause of death and poor prognosis for cancer patients. Therapeutics that prevent tumor metastasis are the key to prolonging the lifespan of cancer patients. Cancer stem cells are believed to be critical in the metastatic process. Recently, drug screening for cancer stem cells reports that antipsychotic drugs displayed(More)
The emergence of NDM-1 containing multi-antibiotic resistant "Superbugs" necessitates the needs of developing of novel NDM-1inhibitors. In this study, we report the discovery of novel NDM-1 inhibitors by multi-step virtual screening. From a 2,800,000 virtual drug-like compound library selected from the ZINC database, we generated a focused NDM-1 inhibitor(More)
