| Abstract | Monocyte adhesion to the vascular endothelium and their subsequent trans-endothelial migration are pivotal early events in atherogenesis. In this study, the effect of delphinidin, belonging to the group of anthocyanin, on adhesion of monocytes to endothelial cells induced by ox-LDL was investigated. The results showed that the pre-treatment with delphinidin (50, 100, or 200 μM) dose-dependently decreased the ox-LDL-induced up-regulation of the expression of ICAM-1 and P-selectin, and the enhanced adhesion and transmigration of monocytes. To determine the role of ROS/p38MAPK/NF-κB pathway, intracellular ROS level, p38MAPK protein expression, NF-κB transcription activity and protein expression, IκB-α degradation, NADPH oxidase subunit (Nox2 and p22phox) protein, and mRNA expression were measured. The results showed that delphinidin attenuated ox-LDL-induced generation of ROS, p38MAPK protein expression, NF-κB transcription activity and protein expression, IκB-α degradation, NADPH oxidase subunit (Nox2 and p22phox) protein and mRNA expression in endothelial cells in a dose-dependent manner. These results suggest that delphinidin attenuates ox-LDL induced expression of adhesion molecules (P-selectin and ICAM-1) and the adhesion of monocytes to endothelial cells by inhibiting ROS/p38MAPK/NF-κB pathway. These findings provide a basis for the design of potent antiatherosclerotic agents that will have therapeutic potential in the prevention of AS. |

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.
