| Abstract | Previously we reported that exposure of mouse and human mast cells to aryl hydrocarbon receptor (AhR) ligands resulted in reactive oxygen species (ROS)- and calcium (Ca2+)-dependent activation of mast cells in vitro and in vivo. However, the mechanisms through which the AhR-ligand axis mediates stress response, Ca2+ signaling and subsequent mast cell activation remain to be fully elucidated. Evidence is provided herein that SHP-2 is critical in regulating AhR-mediated ER stress response and intracellular Ca2+ dynamics. We found that an AhR ligand, FICZ, induced significant reduction of intracellular GSH and an increased level of intracellular ROS. Significantly, we showed that in FICZ-treated mast cells, SHP-2 promoted, in a ROS-dependent manner, ER stress response involving primarily the PERK signaling pathway, ATF4 activation and eIF2α phosphorylation, which could be reversed by the addition of an antioxidant, NAC, and was inhibited in cells with SHP-2 knockdown. Our findings suggested that SHP-2 is critical in controlling ER stress signals in response to AhR activation, which provides a new mechanistic insight into how the AhR-ligand axis regulates cellular adaptation to the environmental insult in mast cells. |

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.
