The course aim is that the student will acquire knowledge of the importance of molecular mechanisms behind transcription control, signal transduction, cell cycle control, and cell differentiation in tumour development. Signal transduction and cell cycle control are conserved processes found in almost all eucaryotic organisms. The area of molecular cell biology has developed dramatically through genetic studies using simple model systems, and is now of fundamental importance for the understanding of tumour-related diseases. The aim is that the student will get sufficient knowledge of genetic model systems and general biological regulatory systems to understand scientific articles within molecular cell and tumour biology. The experimental training includes work with different model organisms and methodology for the study of transcription control, signal transduction, and cell differentiation and proliferation.
