| Abstract | The aim of the study was to investigate the mechanism of arsenic trioxide (As$_{2}$O$_{3}$) in the treatment of malignant pleural effusion (MPE) caused by pleural metastasis of lung cancer. A mouse model of MPE caused by pleural metastasis of lung cancer was first established, and As$_{2}$O$_{3}$ was then intraperitoneally injected to treat the MPE. Mice treated with bevacizumab and bleomycin were included as positive controls, and placebo equivalents were also used as negative controls. The effects of As$_{2}$O$_{3}$ on MPE volume, pleural vessel density, vascular permeability, expression of angiogenic function-related factors, including vascular endothelial growth factor (VEGF) and tumor necrosis factor alpha (TNF-α), as well as nuclear factor-κB (NF-κB) activity in pleural carcinomatosis, were observed. Intraperitoneal injection of As$_{2}$O$_{3}$ reduced the volume of MPE and decreased vascular density and permeability in pleural metastatic nodules in a dose-dependent manner. Moreover, dose-dependent decreases in VEGF and TNF-α expression in MPE, and NF-κB activity in pleural carcinomatosis, were also found after As$_{2}$O$_{3}$ treatment. We showed that As$_{2}$O$_{3}$ can down-regulate VEGF expression via inhibition of NF-κB, and decrease vascular density and permeability in pleural metastatic nodules, thereby eliciting its effects on MPE caused by pleural metastasis of lung cancer. Our results provide a foundation for an As$_{2}$O$_{3}$-based clinical treatment program. |

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.
