| Abstract | Gallic acid (GA) has various biological properties, including an anti-cancer effect. However, little is known about the toxicological effect of GA in primary normal cells in relation to mitogen-activated protein kinase (MAPK) signaling. In this study, we investigated the effects of MAPK (MEK, JNK or p38) inhibitors on GA-treated human pulmonary fibroblast (HPF) cells in relation to cell growth inhibition, cell death, reactive oxygen species (ROS) and glutathione (GSH). GA induced HPF cell growth inhibition and cell death at 24 h, which was accompanied by the loss of mitochondrial membrane potential (MMP; ∆ψm). GA increased ROS levels and GSH-depleted cell numbers in the HPF cells. The MEK inhibitor did not affect cell growth inhibition, cell death, ROS and GSH levels in the GA-treated HPF cells. The JNK inhibitor slightly enhanced cell growth inhibition by GA, while the p38 inhibitor significantly prevented the growth inhibition. Both JNK and p38 inhibitors did not affect cell death, ROS and GSH levels in the GA-treated HPF cells. In conclusion, MAPK inhibitors differentially affected the growth inhibition of GA-treated HPF cells, which were not related to cell death, ROS and GSH levels. |

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.
