ABSTRACT
Type 2 diabetes mellitus (T2DM) is a common chronic metabolic disorder,it results from an interaction of environmental as well as genetic factors.There were several kinds of oral antidiabetic drugs (OADs),including biguanides,sulfonylureas,thiazolidinediones,and meglitinides,etc.Several genes have been identified to be associated with disease development and therapeutic outcomes.Inter-individual variations in the human genome affect both,risk of T2DM development and personalized response to identical drug therapies.Pharmacogenomics approaches focus on single nucleotide polymorphisms and their influence on individual drug response,efficacy and toxicity.Therefore,pharmacogenomics in T2DM is of great importance towards precision medicine which will greatly improve the efficacy of diabetes treatment.In this paper,antidiabetic drugs and related gene polymorphism researches are reviewed.
ABSTRACT
Objective To identify and rename one strain stored in National Center for Medicine Culture Collections ( CMCC) and used for tracheitis vaccine production. Methods The test strain CMCC (B)29108 and the type strain DSM30007T were cultured on NA medium. Characteristics in morphology, physiology, biochemistry and fatty acid profile were compared between the two strains. Phylogenetic analysis was based on 16S rRNA and rpoB gene sequences, together with the DNA-DNA hybridization assay. Results A Comparative analysis of a partial sequence of the 16S rRNA gene sequence revealed that the CMCC( B) 29108 strain was closed to the Acinetobacter species and showed the highest similarity with the type strain Acinetobacter baumannii DSM30007T. Moreover, the CMCC(B)29108 strain was highly similar to type strain DSM30007T in morphology, physiology, biochemistry and fatty acid profile. On the phylogenetic tree based on 16S rRNA and rpoB gene of all Acinetobacter members, the CMCC(B)29108 strain steadily clustered into one independent branch only with the DSM30007 T strain with a DNA-DNA hybridization value of 100%. Conclusion The CMCC(B)29108 strain that is one of the strains used for the production of tracheitis vac-cine should be assigned to the species of Acinetobacter baumannii based on its phenotypic, phylogenetic and chemotaxonomic characteristics.
