| Abstract | Gene expression of eucaryotes is regulated through transcription factors, which are molecules able to attach to the binding sites in the DNA sequence. These binding sites are small pieces of DNA usually found upstream from the gene they regulate. As the binding sites play an important role in the gene expression, it is of interest to find out their characteristics. In this paper, we look for dependencies and independencies between these binding sites using independent component analysis (ICA), non-negative matrix factorization (NMF), probabilistic latent semantic analysis (PLSA) and the method of frequent sets. The data used are human gene upstream regions and possible binding sites listed in a biological database. Also, results on the baker's yeast (S. Cerevisiae) upstream regions are briefly discussed for comparison. ICA, NMF and PLSA are latent variable methods that decompose the observed data into smaller components. Of these, ICA and NMF were originally aimed for continuous data. We show that these methods can be successfully used on discrete DNA data as well. PLSA and the method of frequent sets were created for discrete data sets. The above methods reveal partially overlapping sets of possible binding sites such that the binding sites within a set are dependent of each other. The methods of frequent sets and NMF give a good overview of the most common data structures, whereas using ICA and PLSA we find large sets that are surprisingly frequent. That is, sets of very frequently occurring possible binding sites can be found near hundreds or thousands of genes; also interesting but less frequent ones co-occur surprisingly often. |

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.
