Importance of V-ATPase for cancer cell resistence
Suchánková, Kristýna ; Eckschlager, Tomáš (advisor) ; Indra, Radek (referee)
Chemoresistance is one of the main causes of failure of anticancer chemotherapy. Vacuolar-type ATPase (V-ATPase) is an ATP-dependent proton pump involved in the regulation of the pH in cells, cell organelles and the intracellular space. A significant acidification of the extracellular space and intracellular compartments occurs in connection with the metabolism of tumour cells (glucose metabolism, hypoxia, insufficient blood perfusion of the cancer tissue). Basic drugs are transferred into acidic organelles based on the pH gradient, where they are then protonated and accumulated. This mechanism is called lysosomal sequestration and is one of the mechanisms how tumour cells resist to applied drugs, which then do not reach their target site in cancer cell. An increased expression of V-ATPases has been described in relation to chemoresistance and the progression of tumours. This dissertation is focused on observing the membrane subunit V0d from the complex of V-ATPase and the changes in resistance to ellipticine caused by the silencing of this subunit's gene in human neuroblastoma cell lines UKF-NB-4 (sensitive) and UKF-NB-4ELLI (resistant to ellipticine). The expression of the V0d protein was first examined on mRNA level using real-time polymerase chain reaction (RT-PCR). The silencing of selected...
