Furthermore, Prof. Wu and her group present the first evidence of TR3 on inhibition of oncoprotein MDM2 mediated by p53 (The EMBO Journal, 2006) in their study of cell signal transduction, It is revealed that the TR3s novel function in protecting p53 degradation from MDM2, suggesting TR3 as a potential target to develop new anticancer agents that restrict MDM2-induced tumor progression. Prof. Wu Qiao is working at the School of Life Sciences Although the physiological ligand of TR3 has not been in Xiamen University as the deputy director of the Key identified up to data, Prof. WU and her group recently Laboratory of the Ministry of Education for Cell Biology identified an octaketide, cytosporone B (Csn-B) isolated and Tumor Cell Engineering.

The population dynamics of cotton bollworms in Bt cotton and conventional cotton fields was systemati- cally investigated in Hebei Province from 1997 to 2007. The results combined the model analyses with data obtained from 100 experimental points in North China from 1992 to 2006 demonstrated that the large scale adoption of Bt cotton destroyed the food chain of cotton bollworms shifting among different host crops seasonally. It compressed the ecological niche of cotton bollworm, and it thus not only efficiently reduced the damage of Prof. Wu Kongming is currently engaged in the research cotton bollworm on cotton plants, but also highly sup- to develop technologies and theories for monitoring, pressed the occurrence of cotton bollworm on corn, early warning and control of cotton bollworm populations. soybean, peanut, vegetables and other host plants.
