| Abstract | Nicotine exposure causes the release of dopamine from the ventral tegmental area (VTA) to the nucleus accumbens (NAc). We have previously shown that maternal exposure to nicotine during lactation causes hyperleptinemia in dams and pups, and leptin is known to decrease dopamine release from the VTA. Here we evaluated whether maternal exposure to nicotine during lactation causes changes in dopamine and leptin signaling pathways at the end of exposure and after 5days of withdrawal in the: VTA, NAc, arcuate nucleus (ARC) and dorsal striatum (DS). On postnatal day (PN) 2, lactating Wistar rats were implanted with minipumps releasing nicotine (NIC; 6mg/kg/day, s.c.) or saline (C) for 14days. Offspring were tested in the elevated plus maze (EPM) and open field on PN14 or PN20, and euthanized on PN15 or PN21. Entries into the open arms and head dips in the EPM were reduced in NIC pups at P20. At weaning (PN21), NIC dams had: lower tyrosine hydroxylase (TH), higher OBRb and SOCS3 contents in VTA; lower TH, higher D1R, D2R and DAT contents in NAc; higher TH content in DS; and higher D2R and SOCS3 contents in ARC. On PN15, NIC offspring had higher D1R, D2R and lower DAT contents in NAc, while on PN21, they had lower DAT in DS, and lower pSTAT3 content in ARC. We evidenced that postnatal nicotine exposure induces relevant changes in the brain reward system of dams and pups, possibly associated with changes in leptinemia and increased offspring anxiety-like behavior. |

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.
