| Abstract | Regulator of G protein signaling (RGS) proteins are responsible for the rapid turnoff of G protein-coupled receptor signaling pathways. RGS92, a brainspecific splice variant of the RGS9 gene, is highly expressed in the striatum but lowly expressed in the periaqueductal gray and spinal cord, which mediate various actions of morphine and other opiates. In order to identify the markers that contribute to the genetic susceptibility of heroin dependence, the potential association between heroin dependence and 10 single nucleotide polymorphisms (SNPs), including rs8077696, rs8070231, rs2292593, rs2292592, rs9916525, rs1122079, rs4790953, rs1530351, rs4791230 and rs2869577 of the RGS9 gene was evaluated using the MassARRAY system. The present study recruited 425 heroindependent patients and 205 healthy controls. The results revealed that two SNPs (rs1530351 and rs4791230) located in the promoter region of the RGS9 gene, were significantly associated with heroin dependence (P<0.05). The frequency of the C allele in rs1530351 (χ2=8.031, P=0.005, OR=2.079, 95% CI=1.2413.483) and the G allele in rs4791230 (χ2=7.360, P=0.007, OR=2.021, 95% CI=1.2053.389) in the heroindependent patients was significantly higher than that in the controls. Furthermore, linkage disequilibrium was observed in three blocks (D'>0.9) and significantly less TA haplotypes (χ2=4.867, P=0.027, OR=0.442, 95% CI=0.2100.929) were identified in the heroindependent patients, suggesting that they may exhibit protective effects against heroin dependence. These findings indicate a role for RGS9 gene polymorphisms in heroin dependence and may be informative for future genetic or biological studies on heroin dependence. |

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.
