چکیده :

Type I collagen is among the major extracellular proteins that plays a significant role in cell growth, mutility, migration, proliferation, differentiation, and inflammation. Collagen is involved in the development and progression of many tumors through various signaling pathways and cytokines. The present study investigated the effect of static magnetic field (SMF) 300 mT on the structure and molecular properties of Type I collagens. The purity of collagen was confirmed by SDS-PAGE, its secondary structure properties was revealed by Circular Dichroism (CD) and chemical bound properties by Fourier Transforms Infrared (FTIR) spectroscopy. Also, the Physico-chemical characterization of the collagen was studied using Zetasizer light Scattering and Rheological assay. Our results revealed that The pH of the treated collagen solution increased by while the Zeta potential decreased. The rheological experiments revealed changes in the viscoelastic behavior of collagen due to exposure to SMF 300mT making it less elastic. However, the secondary structure of collagen molecules did not change significantly and the typical positive and negative remained intact. Accordingly, the SMF is considered as a promising biophysical means for targeting type I collagen to control and manipulate cell metastases, motility and division as a prevention and treatment means to tackle with cancer.
