Telosome: biological function and its relationship with tumor / 国际肿瘤学杂志

ABSTRACT

Recent studies show that the structure integrality and function are more important than the length of telomere in maintaining tumor cells reproduction and proliferation.Mammalian telomeres bound by a specialized six-protein(TRF1,TRF2,TIN2,RAP1,POT1 and TPP1 )complex known as telosome or shelterin,has fundamental role in the regulation of telomere activity,maintaining the length and protecting telomere chromosome terminal.Telosome is involved in the complex regulation of cell mitosis process.The study of the role of telomere binding protein complex in tumorigenesis is very important for searching new methods of tumor diagnosis and treatment.
