Diversity and evolution of CYP6 family in insects.
It is important to know the diversity and evolution of CYP6 family in insects in respect to understand the molecular biological mechanism about the occurrence and development of cytochrome P450 mediated insecticide resistance. In this review,the diversity of CYP6 family in insects and the formed reasons, the natural evolutional history, the internal evolutional relationship and the evolutional molecular mechanism of CYP6 family in insects were summarized.
Objective To investigate the relationship between FcγRⅢB gene polymorphisms and susceptibility to chronic periodontitis in Chinese patients. Methods DNA samples with buccal swabs were collected from 63 severe CP patients, 103 initial to moderate CP patients, and 80 healthy controls in Chinese Han nationality. The FcγRⅢB gene polymorphisms were analyzed with PASA. Results There were no significant genotype distribution differences of FcγRⅢB between any two of the three subject groups. Conclusion Further study was needed since we did no find the relationship between the FcγRⅢB gene polymorphism and periodontitis in this present study.
