چکیده

Cancer stem cells (CSCs) are a subpopulation of tumor tissue with the ability to generate tumor cells through the process of self-renewal and differentiation to other cell types. Growing evidence suggests that cancer can be regarded as a metabolic disease and the stem-like behavior of CSCs are also highly controlled by metabolic mechanisms. Given the complexity of metabolism, a comprehensive understanding of metabolic mechanisms underlying tumorigenesis requires a systems approach. Genome-scale constraint-based metabolic models are currently the most advanced tools for quantitative characterization of metabolism. In the present study, we took a constraint-based metabolic reconstruction and analysis (COBRA) approach to develop in silico genome-scale models of glioblastoma multiform (GBM) and its stem cells to enable structural and functional characterization of metabolism in these cells. Our holistic analysis of the metabolic network reflected the current knowledge of GBM and led to identification of novel anti-tumor targets and promising drug repositioning scenarios for synergistic treatment of brain tumor malignancy.

اطلاعات بیشتر در مورد COI

COI مخفف عبارت CIVILICA Object Identifier به معنی شناسه سیویلیکا برای اسناد است. COI کدی است که مطابق محل انتشار، به مقالات کنفرانسها و ژورنالهای داخل کشور به هنگام نمایه سازی بر روی پایگاه استنادی سیویلیکا اختصاص می یابد.

کد COI به مفهوم کد ملی اسناد نمایه شده در سیویلیکا است و کدی یکتا و ثابت است و به همین دلیل همواره قابلیت استناد و پیگیری دارد.
