Molecular Oncology
Code: 45056
ECTS: 6.0
Lecturers in charge: prof. dr. sc. Nada Oršolić - Lectures
Take exam: Studomat
English level:

1,0,0

All teaching activities will be held in Croatian. However, foreign students in mixed groups will have the opportunity to attend additional office hours with the lecturer and teaching assistants in English to help master the course materials. Additionally, the lecturer will refer foreign students to the corresponding literature in English, as well as give them the possibility of taking the associated exams in English.

Description:
LEARNING OUTCOMES:
Students will be able to:
1. Understanding the main steps in the process of carcinogenesis
2. Precise knowledge about mechanisms by which oncogenes, tumor suppressor genes and others factors induced cancer
3. learn the major signaling pathways that lead to tumor progression
4. learn the mechanisms of tumor resistance to apoptosis and apoptosis interact with other forms of cell death
5. understand the importance of epigenetic factors in the modification of oncogenes and tumor suppressor genes
6. understand the process of metastasis, the relationship of the tumor and host during the metastatic cascade
7. Learned the main factors which influence metastatic spread of cancer cells to diferent target tissue
8. gain insight into the molecular pathways of metastasis
9. learn more about the process of creating blood vessels (angiogenesis) in the tumor and the importance and roles of metalloproteinases and other enzymes in cancer
10. learn how to identify key molecular markers of cancer and detection method

EXERCISES:
For students of the Molecular oncology course, practice include microscopy of histological slides of various tumors. Students will have the opportunity to examine samples of tumor tissue colored by immunohistochemistry which will give them a deeper information on the expression of certain proteins within the tumor cells.
On samples of breast cancer we will observe expression of the estrogen receptor, expression of the epidermal growth factor receptor 2 (HER-2), proliferation of cells through expression of Ki-67, the expression of markers of apoptosis, Bcl-2 and Bax and expression of mutated p53 protein. For comparison they will observe two subtypes of breast cancer of varying degrees of aggressiveness and metastatic potential. They will also look at lymph nodes occupied with metastasis of breast cancer.
Samples of melanoma will serve as an example of breakthrough basement membrane by loss of laminin and collagen at the site of penetration and the expression of matrix metalloproteinase-2 and 9 (MMP2, MMP).
They will also look at histology of colon cancer and cervix (CIN III) cancer.
