Institute of Biochemistry and Experimental Oncology (IBEO) is the teaching and research institute of the First Faculty of Medicine, Charles University in Prague The Institute teaches undergraduate medical students in Medical Chemistry and Biochemistry, a compulsory, theoretical, two semestral subject covering basic medical chemistry, biochemistry, inter-organ biochemistry, and molecular biology. The classes are taught in Czech and English languages. The institute teaches cancer pathobiochemistry at 5th semester and it also takes part in the tuition of Biochemistry for bachelors' students.

In the graduate education, the Institute offers programs in biochemistry or genetics for PhD students according to the specialization of research teams.

Research laboratories:

Laboratory of cancer cell biology (head: Aleksi Šedo)

Laboratory of oncogenetics (head: Zdeněk Kleibl)



Head: Aleksi Sedo

Research activities: The laboratory of cancer cell biology (LCCB) was established by Aleksi Šedo, M.D., PhD. in 1997 at the Institute of Medical Chemistry and Biochemistry as a joint laboratory of the 1st Faculty of Medicine, Charles University in Prague and the Institute of Physiology of The Czech Academy of Sciences. In 2002, LCCB joined the Institute of Biochemistry and Experimental Oncology and became its integral part. LCCB focuses on the role of membrane-bound serine proteases in various pathophysiological processes with a special focus on the pathogenesis of cancer and autoimmune disorders. Our results contributed to the definition of the group of “Dipeptidyl peptidase-IV structure and/or activity homologues” (DASH) and to the description of the expression pattern of DASH molecules in autoimmune rheumatoid diseases and in gliomas (CIT).

Currently, the main research interest is the role of the membrane bound proteases dipeptidyl peptidase-IV (DPP-IV) and fibroblast activation protein (FAP) in gliomagenesis. Gliomas are the most frequent primary intracranial tumors. The prognosis for the most common grade IV tumors (glioblastoma multiforme) remains dismal with a median survival of 14 months despite surgical resection and postoperative radiotherapy and chemotherapy. The identification and validation of qualitatively new therapeutic targets and approaches is therefore imperative to improve the limited therapeutic options. Analysis of the bioptic material, functional in-vitro assays as well as in vivo animal models including knock-out mice are being utilized to determine the role of DPP-IV and FAP within the tumor microenvironment and the interactions between malignant glial cells and the stroma with the aim of designing and testing inhibitors or inhibitor based targeting compounds as potential therapeutics.

LCCB closely cooperates with the neurosurgical departments of the Na Homolce Hospital and with the Military University Hospital and the Institute of Organic Chemistry and Biochemistry AS CR, v.v.i. LCCB is the founding member of the Neurooncological section of the Czech Oncological Society of the Czech Medical Association of J.E. Purkyně. The section should facilitate the national and international cooperation between clinical and biomedical disciplines that participate on the diagnostics, treatment and research of malignancies affecting the central nervous system. In addition to the neurooncology field, LCCB participates on the projects exploring the role of DPP-IV and FAP in the pathogenesis of pancreatic adenocarcinoma and possible effects of DPP-IV inhibitors on the immune system in patients with diabetes mellitus.

Research activities: The laboratory has been established by Petr Pohlreich, M.D., PhD. in 1997. It investigates factors contributing to the development of hereditary cancer syndromes with the main focus on hereditary breast and/or ovarian cancer in the Czech population.

Breast cancer (BC) is the most frequent malignant cancer diagnosis affecting Czech female population. It has been estimated that ~5-10% BC cases arise in patients carrying pathogenic alteration BC susceptibility genes; however, the proportion of breast cancer cases influenced by genetic factors is probably much larger. The most frequent BC-susceptibility alterations are found in the two major breast cancer predisposition genes BRCA1 and BRCA2 that code for the large phosphoproteins involved in the dsDNA break repair.

Since foundation of the lab, we identified more than 550 carriers of pathogenic variants in BRCA1 or BRCA2 from 350 families. Our results show that BRCA1 represents the most frequently altered BC susceptibility gene in our population, while mutation in BRCA2 and other tested genes (including CHEK2, ATM, PALB2, p53, NBS1, RAD51C, RAD51D, PPM1D/Wip1, or STK11) participate to BC susceptibility in smaller proportion of high-risk patients (less than 40% of patients with identified pathogenic variant).

Except genetic analyses in the large population series of high risk and unselected cancer patients using classical genotyping as well as high-throughput next-gen sequencing approaches, the laboratory is also involved in functional in vitro analyses of identified variants. Our studies are focused on the analyses of DNA repair capacity following genotoxic insults in modified cells expressing altered genes that code for DNA repair proteins.

We were also involved in pharmacogenomic studies focused on analyses of hereditary variants in genes that code for proteins involved in fluoropyrimidines catabolic pathway. We described variants in these genes that may contribute to the development of serious and body site-specific toxicities in fluoropyrimidine-treated cancer patients.
