| Abstract | Angiotensin II (AngII) is a hormone with long-established cardiovascular actions. Previous studies have revealed an additional role for AngII in the regulation of cutaneous wound healing. To evaluate the association between AngII and abnormal pigmentation of cutaneous wound healing, the present study used human melanocytes to investigate the effects of AngII on melanogenesis, and to elucidate the possible underlying mechanisms. Primary culture melanocytes were treated with AngII either alone or in combination with an AngII type 1 (AT1) receptor antagonist, losartan (LOS). The melanin content and tyrosinase activity were measured and reverse transcription-quantitative polymerase chain reaction (RT-qPCR) and western blotting were performed to assess the proteins involved in melanogenesis and the AT1 receptor. AngII regulated the mRNA expression of AT1 in the melanocytes. The melanin content and tyrosinase activity increased in response to treatment with AngII in a concentrationdependent manner. RT-qPCR and western blotting revealed that the AT1 receptor antagonist, LOS, eliminated this effect. These results provide a novel insight into the role of AngII and its associated signaling in melanogenesis. |

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.
