| Abstract | Heme oxygenase1 (HO1) possesses significant potential as a drug target for hepatitis B, which may be transferable to patient therapy. The aim of the present study was to clarify the dynamic correlation between the hepatitis B virus (HBV) and HO1. The levels of HBV replication and expression of HO1 were investigated in HepG2.2.15 hepatoma cells following exposure to 550 µM hemin for 16 days. The mRNA expression levels of HO1 were then detected using reverse transcriptionquantitative polymerase chain reaction (RTqPCR). HBV replication levels were determined by enzymeimmunoassay and a PCRfluorescence quantitation assay. The results of the present study demonstrated that the mRNA expression levels of HO1 increased in a dosedependent manner in the HepG2.2.15 cells, following exposure to 550 µM hemin. The mRNA expression levels of HO1 reached a peak following exposure of the cells to hemin for three days, subsequently the expression of HO1 decreased. Following exposure to hemin at an optimal concentration of 50 µM for 16 days, the levels of the hepatitis B surface antigen (HBsAg) and hepatitis B e antigen (HBeAg) in the cells were significantly reduced. This marked reduction in the expression of HBsAg and HBeAg reached its peak on the first day, following which the inhibition weakened as the duration of exposure increased. In addition, the inhibition of HBV DNA replication increased with the a longer duration of exposure. Furthermore, HBV DNA levels were significantly decreased following exposure to hemin for 36 days. In conclusion, the present study demonstrated that induced expression of HO1 interfered with HBV replication in a dose and timedependent manner, implying that a reduction of the HBV viral load may contribute to upregulation in the expression of HO1. |

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.
