   Механизмы устойчивости опухолей к цисплатину

цисплатина. Результати цієї роботи вказують на можливість участі

продукту гена v-src в індукції резитентності до цисплатина шляхом

модуляції деяких шляхів репарації ДНК [111].

Ампліфікація гена сорцина (кальцій-звязуючого білка з

молекулярною масою 19-22кД) в деяких модельних системах асоціювалася

з резистентним фенотипом [112]. Важко зараз сказати, чи є

резистентність пов`язаною саме з сорцином чи разом з геном сорцина у

клітинах ампліфіковані і інші, більш важливі для розвитку

резистентності гени.

Таким чином резистентність до цисплатина має комплексний

характер і пов`язана з рядом особливостей клітин на рівні

цитоплазматичної мемрани, внутрішньоклітинних систем детоксикації,

систем репарації та порушення функціональної активності генів p 53,

bcl-2, fos, mdm 2, nm23та інших.
