BACKGROUND: Tumor is an abnormal cell growth that spreads to other organs. Breast tumor develops in the tissues of the breastRegular exercise can help to lower the chance of developing breast tumor. For the year 2020, the expected incidence of tumor patients in India was 679,421 (94.1 per 100,000) for males and 712,758 (103.6 per 100,000) for females.. AIM: To analyse the endogenous over the expression of catalase as an inhibitor of EMT signaling in breast tumor through molecular docking.
 
MATERIALS AND METHODS:
            The molecular docking analysis is a bio informatic study conducted in a private dental college. The endogenous substance catalase which is secreted after post exercise is used as our target protein. The interaction of catalase with the proteins relevant to breast tumor namely Vimentin, Beta-catenin, Ecadherin are included for docking analysis. The protein structure is retrieved using protein data bank, Protein protein docking done using patch Dock server followed by visualisation of protein-protein interaction using pymol.
 
RESULT:
             The surface representation of catalase with Vimentin, Beta-catenin and Ecadherin showed good shape complementarity.The results showed that Catalase forms strong interaction with Vimetine, Beta catenin, Ecatherine proteins in terms of hydrogen bond interaction, hydrophobic and non bonded interaction. Through this interaction these proteins might control the overexpression of catalase activity in breast tumor.
 
  CONCLUSION:
           From the obtained result it can be concluded that catalase may have a protective role against breast tumor through its interaction with Vimentin, E-Cadherin, Beta-Catenin. The present study has suggested a possible mechanism of catalase in the inhibitor of EMT signaling in breast tumor.

Background: Breast tumor is the most common tumor in women and the second leading cause of tumor death in women, after lung tumor. As people get older, their chances of developing breast tumor increase. Breast tumor is a major health concern in developed countries. Glutathione is an endogenous antioxidant that helps maintain quality of life and may help prevent breast tumor. The role of endogenous glutathione as a regulator of Wnt/beta catenin signalling in breast tumor will be studied using molecular docking.. Materials and Methods: The molecular docking analysis is a bio-informatic study executed in a dental college. The endogenous substance Glutathione which is secreted after exercise is used as a target protein. The interaction of glutathione with proteins relevant to breast tumor namely Beta catenin , MYC are included for docking analysis. The protein structure is retrieved using protein data bank, Protein protein docking done using patch dock server followed by visualisation of protein- protein interaction using pymol. Results: The surface representation of Glutathione with Beta-catenin,MYC complex showed good shape complementarity. The number of structurally aligned residues indicates anticipated binding free energy for the top-listed solutions. Conclusion: The findings suggest that exercise-induced endogenous glutathione may operate as a regulator of wnt/beta catenin signalling in breast tumor. The exercise may help maintain gene expression balance by modifying the Wnt/beta catenin signalling system, as well as operate as a protective factor in preventing, controlling, and aiding as an additional therapy for breast tumor with a favourable prognosis.
