We have screened 11 isoquinoline derivatives and α-methylene-γ-butyrolactones using the 3-(4,5-dimethylthi-azol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) cytotoxicity assay in HeLa and HEK-293T cells. Compound 2 was identified as potential anticancer agent. To further improve its therapeutic potential, this agent was incorporated into transferrin (Tf)-conjugated liposomes (LPs) for targeted d...

background: micropatterning is becoming a powerful tool for studying cells in vitro. this method not only uses very small amount of material but also mimic the microenvironment structure present in living tissues better than flask culturing techniques. in previous studies using micropatterning of extracellular matrix proteins on glass surfaces, the rate of protein detachment from the surface wa...

Ephrin-B1,-B2 and -B3 proteins share a high degree of sequence similarity. Investigation these as putative prognostic markers in human cancers including oral squamous cell carcinoma (OSCC) has been limited by challenges generating specific antibodies against them. The current study examined the reactivity polyclonal anti-human ephrin-B2 antibody (HPA008999) ephrin-B investigated significance im...

Large conductance Ca(2+)-activated K(+) (BK(Ca)) channels encoded by the Slo1 gene (also known as KCNMA1) are physiologically important in a wide range of cell types and form complexes with a number of other proteins that affect their function. We performed a yeast two-hybrid screen to identify proteins that interact with BK(Ca) channels using a bait construct derived from domains in the extrem...

The mechanism underlying the crosstalk between multiple G protein–coupled receptors remains poorly understood. We previously reported that prostaglandin E receptor EP1 facilitates dopamine D1 receptor signaling in striatal slices and promotes behavioral responses induced by D1 receptor agonists. Here, using human embryonic kidney (HEK)-293T cells expressing D1 and EP1, we have analyzed the mech...
