| Abstract | Cancer cachexia is a complex metabolic syndrome that cannot be fully reversed by conventional nutritional support, and leads to the progressive wasting of body tissues, particularly the loss of lean muscle mass. Formoterol, a highly selective β2-adrenoceptor therapeutic drug, gives potential anabolic responses in the context of skeletal muscles and was widely confirmed to possess anti-cachexia effects. However, the possible metabolic pathways and the metabolite changes that initiate and maintain these anabolic responses remain poorly understood. In the present study, a 1H NMR-metabonomics model was established to investigate the metabolic features of cancer cachexia and the contribution of formoterol to serum metabolites in a mouse model bearing CT26 carcinoma cells. Among the metabolic processes found in serum, the ones associated with cancer are glycolysis and lipid lipolysis. However, the citrate cycle and amino acid metabolism are the major metabolic characteristics of cachexia. Furthermore, formoterol stimulated skeletal muscle growth, increased the body weight and altered the metabolic profile. Amino acids, ketone bodies and citrate cycle metabolites are potential biomarkers associated with these functional pathways. Taking the pathways of cancer cachexia into account, formoterol could regulate the imbalance in glycolysis, the citrate cycle, and in lipid and amino acid metabolism. Collectively, these results indicate that formoterol partially reverses the metabolic disturbances associated with cachexia. |

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.
