 Margit Balázs MSc DSc

Scientific degree

  • PhD/cell biology/1995
  • DSc/basic medical sciences/2003

Teaching

Course leader

  • Basic oncology
  • The use of molecular biological techniques in epidemiological studies
  • The role genetic predisposition in the development of malignant diseases
  • Investigation of genetic instability an clonal progression of malignant melanomas
  • The basics of fluorescence in situ hybridization
  • Array comparative genomic hybridization and the use in clinical diagnosis

Contributing teacher

  • Preventive medicine and public health
  • Genetic epidemiology
  • Molecular biology
  • Basic oncology

Research

  • key-words: molecular genetics of malignant diseases, FISH, CGH, gene copy alterations and gene expression, genetic background of malignant melanomas and head and neck cancers
  • Investigation of genetic alterations associated with tumor progression in order to identify molecular genetic markers that might be targets for cancer  diagnosis and therapeutics.
  • Fluorescence in situ hybridization (FISH), comparative genomic hybridization (CGH), laser microdissection, immunhistochemistry, Affymetrix gene expression analysis using the Genespring sofware.


Our major subtasks are: study of

  • molecular mechanisms of tumor invasion and progression, description of genetic alterations in early-stage lesions, identification of invasion specific genetic markers.
  • molecular alterations associated with metastasis formation, early detection of alterations that might help to predict metastatic behavior of primary tumors.
  • organ specific genetic markers of metastases, comparison of genomic alterations and gene expression patterns between primary tumors, lymph node and distant metastases obtained from the same patient.
  • detection of chromosome copy number alterations in interphase cells and on metaphase chromosome preparations. 


Research projects (ongoing):

  • NKFP 1-00003/2005; 257.000.000 HUF; 2005-2008  Potentials of preventing diseases of major public health importance (subproject leader)
  • OTKA T 048750, 2005-2008, 17.200.000 Ft Association between genomic alterations and gene expression, search for genetic markers in association with melanoma metastasis formation (project leader)
