| Abstract | To study the mechanism of transcription and expression of the myostatin gene, we cloned and analyzed the sequence of the bovine myostatin gene promoter and first intron from Qinchuan and Red Angus cattle, then constructed eukaryotic expression vectors encoding the GFP vector by replacing the CMV promoter with the bovine myostatin promoter using PCR method, thereby obtaining an expression vector coding GFP report gene with first intron (identified as pEGFP-MSTNPro-intron1). By transfecting C2C12 cells with the vectors, we then compared the effect on GFP gene expression of the promoter and normal first intron of Qinchuan and Red Angus cattle with that from the promoter and a Qinchuan allele with a 16 base pair insertion. After 48 h incubation, fluorescent indices (FIs), which indicate the expression rate and intensity of gene GFP expression, were analyzed by flow cytometry (FCM). Results showed that Qinchuan sequence homology of promoter was 99% with Red Angus, that Qinchuan first intron sequence homology was 99.51% with Red Angus and that first intron homologies of Qinchuan and Red Angus were 99.08 and 99.02%, respectively, with Accession No.AF320998 in GenBank. Expression of the GFP gene did not differ significantly between preparations using the Qinchuan versus Red Angus promoter. Preparations with a construct that included the first intron had higher GFP gene expression in C2C12 cells than those whose construct lacked the first intron (P < 0.05 or P < 0.01). However, there was no significant difference (P > 0.05) in gene expression between normal first intron and 16 bp insertion first intron (+16 bp) preparations. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
