| Abstract | Recently, retrospective studies provided conflicting results on the benefit of ß-adrenoceptor-blockers (ß-blockers) on melanoma progression. Most of these studies did not define the ß-blocker used, making it difficult to understand the source of discrepancies between results. Therefore, we investigated the effect of non-cardioselective and cardioselective ß-blockers on melanoma progression at the cellular, molecular, and tumor levels. Here we show that the non-cardioselective ß-blocker propranolol hydrochloride (propranolol) inhibits proliferation and induces apoptosis in primary cell cultures derived from a primary and a metastasis of human melanoma and in melanoma cell lines. In contrast, the cardioselective ß-blocker metoprolol tartrate hardly affects melanoma cell survival or proliferation. We further highlight that a daily treatment with propranolol slows down tumor development in immunodeficient mice transplanted with human melanoma cells. RNA microarrays, quantitative PCR, and histochemistry analyses showed that propranolol regulates the expression of different genes involved in tumor angiogenesis, cell death, or proliferation. Thus, our results suggest that non-cardioselective ß-blockers affect melanoma progression, and bring first clues about the pathways involved in this antitumor effect. |

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.
