The quantitative structure-activity relationships (QSARs) for polychlorinated biphenyl (PCB) congeners have been determined by comparing the EC50 values for three in vitro test systems, namely, aryl hydrocarbon hydroxylase (AHH) and ethoxyresorufin O-deethylase (EROD) induction in rat hepatoma H-4-II-E cells and competitive binding avidities to the rat(More)
Emphasis was put on the comparative quantitative structure-activity approaches to the exploration of action mechanisms of structurally different classes of compounds showing the same type of activity as well as those of the same type of compounds having different actions. Examples were selected from studies performed on insecticides and plant growth(More)
Cancer/testis antigens (CTAs) are known to be expressed in various cancer types but are minimally or not expressed in normal tissues except for germline tissues. CTAs are attractive targets for cancer immunotherapy and diagnosis because of their restricted expression. The mechanisms of CTAs expression are unclear because the inducers of CTAs expression(More)
Influenza virus (IFV) infection is a common cause of severe pneumonia. Studies have suggested that excessive activation of the host immune system including macrophages is responsible for the severe pathologies mediated by IFV infection. Here, we focused on the X11 protein family member Mint3/Apba3, known to promote ATP production via glycolysis by(More)
1. The depolarizing afterpotential induced by phenothrin and methoxychlor in crayfish giant axons was measured intracellularly. 2. Changes in the K+ ion concentration did not affect the depolarizing afterpotential when evaluated as the membrane potential. 3. Addition of tetrodotoxin or replacement of the Cl- ions by OAc- ions or of the Na+ ions by choline(More)
