To investigate the role of SH-2-containing pro- tein tyrosine phosphatase 1, SHP-1, in IL-4-induced IL-4 receptor (IL-4R) expression, we examined IL-4 receptor α-chain (IL-4Rα) mRNA expression in Na3VO4-treated wild...
Calcineurin (CN) is the only protein phosphatase known to be under the control of calcium (Ca2+) and calmodulin (CaM). The enzyme consists of two subunits, the catalytic A subunit of 61 ku (CNA) and a regulatory B sub...
A pot experiment has been carried out under controlled conditions to study the possibility of applying the technique of in vivo staining for acid phosphatase activity on the roots of mycorrhizal plants and arbuscular ...
The effects of simulated microgravity on matrix mineralization of chondrocytes were examined using cultured chicken embryonic chondrocytes as the model. In four days, there was a time course decrease in alkaline phosp...

It has been confirmed that tyrosine phosphorylation and dephosphorylation play crucial roles in the regulation of cellular growth, proliferation, differentiation and transformation. However, the systematic study on nu...
Malsumura and Hogendijk (1964) found that there was a difference in phosphatase activity between organophosphorus (OP)-resistant and sensitive (SEN) strains of houseflies. Welling et al. (1971) found that the resistan...
