| Abstract | Complement factor B, a serine protease playing a pivotal role in alternative pathway activation, is an acute-phase plasma protein. Previous studies have revealed that interleukin-1 (IL-1) mediates, at least in part, the acute-phase induction of factor B expression and that the IL-1-responsive element resides in the region between -553 and -478 relative to the transcription initiation site of the mouse factor B gene. In this paper, we demonstrate a specific binding site for a nuclear factor of human hepatoma HepG2 cells in this region of the factor B gene, using gel shift and methylation interference analysis. The nucleotide sequence of the binding site is closely similar to the NF kappa B or H2TF1 binding motif. The binding activity of HepG2 showed very similar specificity to that of NF kappa B or H2TF1, as shown by a competition binding assay, and was induced by IL-1 alpha treatment. A synthetic oligonucleotide corresponding to this binding site, as well as a similar sequence found in another class III complement C4 gene, conferred IL-1 responsiveness on the minimal factor B promoter. In contrast, a mutated oligonucleotide that could not bind to the HepG2 nuclear factor did not confer IL-1 responsiveness. These results suggest that IL-1 induces factor B expression via NF kappa B or a closely related factor in hepatocyte nuclei. |

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.
