- Prerequisites
- Bi7070 Physiology of Cell Systems
Basic knowledge of biochemistry, cell physiology and molecular biology and passing through lecture of Physiology of cell systems are neccessary. - Course Enrolment Limitations
- The course is also offered to the students of the fields other than those the course is directly associated with.
- fields of study / plans the course is directly associated with
- there are 9 fields of study the course is directly associated with, display
- Course objectives
- The course gives a complex view of the process of carcinogenesis, including mutagenic (genotoxic), epigenetic, and non-genotoxic factors that play a role during the development of cancer. Molecular and biological principles of changes in extra-, inter-, and intracellular communication leading to disruption of cellular proliferation, differentiation, and apoptosis and the role of stem cells, specific signalling pathways, and tumour microenvironment in cancer development are explained. The students obtain knowledge of development of frequent cancers such as leukemias, colon, prostate, breast, lung, liver, and skin cancer including specific mechanisms. Next, the role of environmental factors, especially dietary lipids and lipid metabolism in carcinogenesis is explained. Finally, possibilities and importance of recent diagnostic and therapeutic approaches including mechanisms of action of specific drugs are described.
- Learning outcomes
- At the end of the course students should be able to: understand a complex view of the process of carcinogenesis, including mutagenic (genotoxic), epigenetic, and non-genotoxic factors that play a role during the development of cancer; explain and understand basic processes leading to cancer development including metastases on the level of cells and cellular polupations; interpret molecular and biological principles influencing extra-, inter-, and intracellular communication and specific signal transduction leading to disruption of cellular proliferation, differentiation, and apoptosis; explain the role and importance of stem cells, specific signalling pathways and tumour microenvironment in cancer development; describe mechanisms of frequent cancer type development (leukemias, colon, prostate, breast, lung, liver, and skin cancer); understand mechanisms of the effects of environmental factors, especially dietary lipids and lipid metabolism in carcinogenesis; discuss questions of cancer prevention, diagnosis and therapy; use acquired knowledge of new research results from described areas for prevention and new therapeutic strategies.

- Teaching methods
- Lectures and class discussion. Learning answers for individual lectures in e-learning didacting material.
- Assessment methods
- Attendance of the lectures is not mandantory but highly recommended for right understanding of the subject matter. During lectures, students are asked about subjects of past lectures. The course is finished first by short written exam. Students must answer about 10 questions which go through all topics discoursed. This is followed by detail oral examination which is evaluated together with written exam by the teacher.
