... was normalized by the renilla luciferase activity in the same well. To construct the STAT3-driven promoter, the 2 · APRE sequence was cloned into the multiple cloning site of the pGL3–TATA plasmid, ... signaling pathway [15,16]. On the other hand, the MAPK pathway has been shown to have an important role in the regulation of STAT3 signaling [17,18]. We thus examined the po...

... showed the presence of the CSB dimer in the nucleus of HeLa cells. We further show that dimerization occurs through the central ATPase domain of the pro- tein. These results have implications for the ... Thus, these results suggest that the CSB protein, under the experimental conditions used, functions as a multimer. Furthermore, the Hill coeffi- cient of 2.1, which is the...
