| Abstract | Baicalein is a bioactive flavonoid that is widely used in ancient China. However, its effects on the most common primary malignant bone tumor, osteosarcoma, remain unknown. In the present study, we investigated the effects of baicalein in osteosarcoma cells. Our results indicate baicalein might be an efficacious anti-osteosarcoma drug. We found that baicalein could inhibit cell proliferation in a time- and dose-dependent manner. Additionally, we demonstrated that baicalein promotes osteosarcoma cell apoptosis, and our mechanistic studies suggest that this is mediated by caspase activation, especially caspase-3. We also showed that the down-regulation of Bcl-2 and concurrent increase in Bax and Bim levels contribute to the apoptosis induced by baicalein. In addition, we observed that baicalein induces G1 cell cycle arrest by decreasing cyclin D1 and cyclin-dependent kinase 4 (CDK4). Furthermore, our data verifies that baicalein can reduce osteosarcoma cell adhesion, migration and invasion in vitro, which indicates its potential to inhibit osteosarcoma metastasis. The decrease in expression of matrix metalloproteinases (MMP)-2 and MMP-9 may contribute to the effects of baicalein. Taken together, our results provide evidence that baicalein plays important roles in anti-osteosarcoma therapy, and thus may serve as a novel and efficient candidate agent for osteosarcoma treatment. |

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.
