AN INTEGRATED NETWORK ANALYSIS OF PSORIASIS: A NOVEL APPROACH TO DISEASE PATHOLOGY

Objective: Psoriasis is a chronic autoimmune disorder. At present, about 2% of human population is affected by psoriasis in a global scale.There is no permanent cure for psoriasis in the post-genomic era and the disease mechanism too is poorly understood. We hereby investigatepsoriasis through a systems biology approach to identify the underlying regulatory networks, which are pivotal to the disease pathology ofpsoriasis.Methods: Initially, we surveyed microarray studies from array express, and then we extracted the list of implicated genes through array mining tools.We then verified the nomenclature of extracted genes and extracted gene ontology information from various publications and databases such as UCSC,HUGO, and DAVID. We then have identified the list of novel micro RNA (miRNAs), transcription factors and pathways, which are involved in the diseasepathology of psoriasis from EnrichR.Results: EnrichR predicted 193 miRNAs, 183 transcription factors, and 116 pathways. After applying various mining techniques and statistics, weidentified a very few transcriptions factors and miRNAs, which are related to the disease pathways of psoriasis. Finally, we have used t-test to identifya specific miRNA and transcription factors, which are associated with the disease pathology of psoriasis on the basis of pathway analysis and it wasidentified that hsa-miR-324-5p and PAX3 have a higher degree of association on the basis of p-value.Conclusion: Integrated network analysis of biological data is an exciting view point to view and understand the pathological conditions in a biologicalsystem, but until date this field has not developed enough to encompass etiology and therapy. In order to take an equilibrium shift from the level ofdisease understanding to pattern characterization and therapy, there is a requirement for conducting more experimental studies on human with therespective ailments. At present, we have applied the approach of network analysis to psoriasis and in future we will be applying this approach tounderstand the disease pathology of various disorders of autoimmune nature.Keywords: Psoriasis, Micro RNA, Post-genomics, Bioinformatics and systems biology

MOLECULAR DOCKING OF ANTITRYPANOSOMAL INHIBITORS FROM EUCALYPTUS TERETICORNIS FOR SLEEPING SICKNESS

Objectives: This study aims to investigate the antitrypanosomal inhibitors of Eucalyptus tereticornis for sleeping sickness through molecular docking and studies on Absorption distribution metabolism excursion and toxicology (ADMET). Methods: In silico molecular docking in ArgusLab software and ADMET analysis in AdmetSAR software was performed for the antitrypanosomal inhibitors of E. tereticornis for sleeping sickness. Results: Interactions were studied for the ten proteins responsible for sleeping sickness with the 50 antitrypanosomal inhibitors of E. tereticornis. Docking was performed to see the interaction and the best binding energy of compounds with the proteins involved in sleeping sickness. The docking scores were highest for betulonic acid with −15.66 kcal/mol followed by euglobal with −12.24 kcal/mol, B-pinene with −10.313 kcal/mol, A-pinene with −10.3418 kcal/mol, and the least docking score for P-cymene with −10.6045 kcal/mol. Docking results showed that only betulonic acid and euglobal showed that hydrogen bond interaction was as b-pinene, a-pinene, and p-cymene yielded no hydrogen bond interactions so we will be taking the former docking results for further studies. The best docking result was shown by betulonic acid with trypanothione reductase giving binding energy of −15.66 kcal/mol with hydrogen bond interaction of 2.9, so this result was taken for further analysis. Conclusion: The results of the compound extracted from E. tereticornis will become physiological relevant only when (i) the pure compounds of this plant is available in large quantities; (ii) the Eucalyptus is biochemically stabilized to avoid degradation and enhance absorption in the gastrointestinal tract; and (iii) special delivery methods for this drug to reach the areas of treatment. In this work, the efficacy of E. tereticornis to act against trypanosomal protein was initiated and thus further research in this process would help us to take full advantage of the remedial effects of the compounds extracted from this plant
