| Abstract | To gain more knowledge about the physiological regulation of metal pollutant detoxification in grass carp, we examined Cd concentration and its the potential influence on the expression of metallothionein 2 (MT2) and multidrug resistance protein 2 (ABCC2) mRNA in the liver and kidney, using in vitro and in vivo experiments. First, the full-length of MT2 cDNA and partial ABCC2 cDNA was obtained, consisting 183bp and 366bp respectively. In vivo approach, grass carp received 96h exposure of Cd (1/10 LD50), and MT2 and ABCC2 mRNA expression were determined by qRT-PCR. The Cd treatment resulted in an increase of MT2 mRNA level in the liver with Cd accumulation. Nonetheless, the elevation ABCC2 mRNA in the liver was appeared at 48h after Cd exposure, as well as the expression of MT2 and ABCC2 mRNA in the kidney. The in vitro experiment was carried out using the hepatocyte (L86) and nephroblasts (CIK). The qRT-RCR results showed that MT2 and ABCC2 mRNA dramatically increased following Cd exposure (1/10 LD50); however, ABCC2 mRNA expression was suppressed in the L86 cell line at first (6h). In conclusion, this result suggested that both MT2 and ABCC2 mRNA may play important roles in the detoxification of toxic metals, and MT2 gene was more sensitive to Cd induction. |

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.
