Short personal activity proposal for the COST Action CA15135 (max 1000 characters)
| Evaluation of cytotoxic/cytostatic effects and antitumor activity of new compounds/molecules.
A wide range of cell cultures [primary cultures and permanent cell lines; cancer and non-cancer cells; animal and human cells; cell cultures established from cancers of various origin, histological type, etiology; drug-sensitive and drug-resistant cancer cells] will be used as model systems in our studies.
The investigations will be performed by short-term (2-4 to 96 h, with monolayer 2D cell cultures) and long-term (16-18 to 30-40 days; with 3D cancer cell colonies) experiments using methods with different molecular/cellular targets and mechanisms of action such as MTT assay, neutral red uptake cytotoxicity assay, crystal violet staining, double staining with acridine orange and propidium iodide, LDH cytotoxicity assay, TUNEL test, Annexin V propidium iodide staining, colony-forming method, etc.
Preparation of experimental and review articles, presentations and other educational materials.
