Molecular and cellular mechanisms of glioblastoma resistance to vascular endothelial growth factor inhibitors

Молекулярные и клеточные механизмы резистентности глиобластомы к ингибиторам фактора роста эндотелия сосудов

Molecular and cellular mechanisms of glioblastoma resistance to vascular endothelial growth factor inhibitors

Abstract

Представлен обзор современных источников литературы, посвященных изучению молекулярных и клеточных механизмов резистентности глиобластомы к антиангиогенным лекарственным средствам. Ангиогенез представляет собой важнейший патофизиологический механизм роста и прогрессирования глиобластомы за счет активного развития микрососудистой сети. Ускоренное развитие микрососудистой сети в глиобластоме происходит благодаря синтезу опухолевыми клетками большого количества фактора роста эндотелия сосудов (Vascular Endothelial Growth Factor, VEGF). Среди основных молекулярных и клеточных механизмов лекарственной устойчивости глиобластомы к анти-VEGF агентам принято относить VEGF-независимые пути ангиогенеза, активность клеток костного мозга и перицитов, а также сосудистую кооперацию, периваскулярную инвазию и феномен аутофагии. Изложены современные данные о рациональном и наиболее эффективном использовании анти-VEGF-лекарственных средств у пациентов с глиомами высокой степени злокачественности. Обозначены актуальные, остающиеся нерешенными вопросы, что обусловливает необходимость проведения дальнейших экспериментальных и клинических исследований, посвященных изучению механизмов лекарственной устойчивости глиобластомы к анти-VEGF-препаратам. This state-of-the-art review focuses on molecular and cellular factors associated with glioblastoma resistance to antiangiogenic drugs. Angiogenesis is an important pathophysiological mechanism for the growth and progression of glioblastoma facilitated by active development of microvasculature. The accelerated development of the microvascular network in glioblastoma occurs due to the synthesis of a large number of vascular endothelial growth factor (VEGF) by tumor cells Among the major molecular and cellular factors, glioblastoma drug resistance to anti-VEGF agents is commonly attributed to VEGF-independent pathways of angiogenesis, bone marrow cell and pericyte activity as well as to vascular co-option, perivascular invasion, and the phenomenon of autophagy. The authors provided current data on the rational and most effective use of anti-VEGF drugs for patients with high-grade gliomas. Relevant unsolved problems associated with drug resistance of glioblastoma to anti-VEGF drugs were highlighted.
