What are receptor tyrosine kinases?
Receptor tyrosine kinases are proteins that play a crucial role in cell signaling and are often implicated in cancer.
How is target inhibition confirmed?
Target inhibition is confirmed using Western blot analysis in cultured leukemia cells.
What is a clonogenic assay?
A clonogenic assay measures the ability of cells to grow into colonies, indicating their functional activity.
What role do pharmacodynamic studies play?
Pharmacodynamic studies assess the effects of drugs on the body, helping to determine effective dosing schedules.
How is therapeutic efficacy evaluated?
Therapeutic efficacy is evaluated using bioluminescent imaging in vivo.
