Cancer arises from mutations in the critical genes that allow healthy cells to escape cell cycle regulation and acquire the ability to proliferate ...
Прогрессирование опухоли
Прогрессирование опухоли
Tumor progression is a phenomenon where the pre-formed tumor acquires successive mutations to become clinically more aggressive and malignant. In the ...
Адаптационные механизмы в раковых клетках
Адаптационные механизмы в раковых клетках
Cancer cells accumulate genetic changes at an abnormally rapid rate due to the defects in the DNA repair mechanisms. From an evolutionary perspective, ...

The Ras-gene-encoded proteins are regulators of signaling pathways controlling cell proliferation, differentiation, or cell survival. The Ras-gene family ...
Передача сигналов mTOR и прогрессирование рака
Передача сигналов mTOR и прогрессирование рака
The mammalian target of rapamycin or mTOR protein was discovered in 1994 due to its direct interaction with rapamycin. The protein gets its name from a ...
Раковые стволовые клетки и поддержание опухоли
Раковые стволовые клетки и поддержание опухоли
Early diagnosis and treatment can often cure cancer. However, even with treatment, residual cells called cancer stem cells (CSC) might remain, often ...
Мышиные модели исследования рака
Мышиные модели исследования рака
Mice have long served as models for studying human biology and pathology because of their phylogenetic and physiological similarity with humans. They are ...
