Introduction: The GLP1R gene provides the necessary instruction for the synthesis of the insulin hormones which is needed for glucose catabolism. Polymorphisms in this gene are associated with diabetes. The protein is an important drug target for the treatment of type-2 diabetes and stroke. Material and Methods: Different nsSNPs and protein-related sequences were obtained from NCBI and ExPASY database. Gene associations and interactions were predicted using GeneMANIA software. Deleterious and damaging effects of nsSNPs were analyzed using SIFT, Provean, and Polyphen-2. The association of the nsSNPs with the disease was predicted using SNPs & GO software. Protein stability was investigated using I-Mutant and MUpro software. The structural and functional impact of point mutations was predicted using Project Hope software. Project Hope analyzes the mutations according to their size, charge, hydrophobicity, and conservancy. Results: The GLP1R gene was found to have an association with 20 other different genes. Among the most important ones is the GCG (glucagon) gene which is also a trans membrane protein. Overall 7229 variants were seen, and the missense variants or nsSNPs (146) were selected for further analysis. The total number of nsSNPs obtained in this study was 146. After being subjected to SIFT software (27 Deleterious and 119 Tolerated) were predicted. Analysis with Provean showed that (20 deleterious and 7 neutral). Analysis using Polyphen-2 revealed 17 probably damaging, 2 possibly damaging and 1 benign nsSNPs. Using two additional software SNPs & GO and PHD-SNPs showed that 14 and 17 nsSNPs had a disease effect, respectively. Project Hope software predicts the effect of the 14 nsSNPs on the protein function due to differences in charge, size, hydrophobicity, and conservancy between the wild and mutant types. Conclusion: In this study, the 14 nsSNPs which were highly affected the protein function. This protein is providing the necessary instruction for the synthesis of the insulin hormones which is needed for glucose catabolism. Polymorphisms in this gene are associated with diabetes and also affect the treatment of diabetic patients due to the fact that the protein acts as an important drug target.展开更多

They know answers of exercises from it before they do them. Some of them just copy down the right answers and wait for teacher’s praise. In this situation, College English teachers should redesign the exercises after each unit so that students will be interested and involved in learning. This study thus suggests several ways to redesign the vocabulary exercises from “ College English". It expects, on the one hand, to raise College English teachers’ awareness of the necessity to change the exercises. On the other hand, it expects to give them an inspiration, and example of designing more appropriate exercises so as to reinforce students’ vocabulary and enhance their language awareness.展开更多

Apple whole genome sequencing has been completed, which provided an excellent opportunity for genome-wide analysis of the synonymous codon usage patterns. In this study, a multivariate bioinformatics analysis was performed to reveal the characteristics of synonymous codon usage and the main factors affecting codon bias in apple. The neutrality, correspondence, and correlation analyses were performed by Codon W and SPSS(Statistical Product and Service Solutions) programs, indicating that the apple genome codon usage patterns were affected by mutational pressure and selective constraint. Meanwhile, coding sequence length and the hydrophobicity of proteins could also influence the codon usage patterns. In short, codon usage pattern analysis and determination of optimal codons has laid an important theoretical basis for genetic engineering, gene prediction and molecular evolution studies in apple.展开更多

[Method] Relative codon usage patterns of MaBSP were calculated using the software CodonW version 1.4.2. and the web-based tool(http://kazusa.or.jp/codon/).[Result] Our findings showed that C-ended and G-ended codons were the most preferential except the TER codon UGA which was coded for by just one codon. The ENc value, relationship between AT bias and GC bias, Random synonymous codon usage(RSCU) and CAI all showed that codon bias usage existed in MaBSP gene.[Conclusion] The codon usage patterns of MaBSP gene is principally influenced by natural selection in the third position. However, other multiple factors also influence this pattern.展开更多

Results:Two hundred and seventy five acute phase samples were screened by RT-PCR.of which 149(54.18%) showed positivity for CHIKV.Later on 192 convalescent phase samples were tested for CHIKV specific antibodies in which 125(65.10%) samples were found to be positive.Four CHIKV strains were selected and subjected to cloning followed by nucleotide sequencing and were submitted to the Genbank DMA database with the Accession numbers(GQ119362,GQ119363, GQl 19364,and FJ225403).The Sequence analysis of "CHIK-Kadapa" strain(GQ119362) with other CHIKV isolates suggested that the present CHIKV strain has(99.23±0.52)%and 100%identity with Central East South African isolates(CESA) at nucleotide and amino acid levels respectively.Two unique non synonymous mutations S168L and D183V were depicted in El gene of the selected strains of the present study.Conclusions:The 14 months survey revealed the circulation of CHIKV in 2008-2009 in Andhra Pradesh and the causative agent is identified to be of Central East South African(CESA) origin.The importance of the non synonymous mutations(S168L and D183V) and their role in the mobility and strength of the El-El and E1-E2 interactions needs further investigations.The study also urges the need for intensifying the epidemiological and entomological surveillance to combat any such CHIKV outbreak in the near future.展开更多
