Resumen

AMOR-VIGIL, Ana María et al. Relevant results in molecular Biology, enzymopathies and citogenetics during 1996-2010. Rev Cubana Hematol Inmunol Hemoter [online]. 2011, vol.27, n.1. ISSN 0864-0289.

The Department of Cellular and Molecular Biology of the Institute of Hematology and Immunology includes 4 areas: molecular biology, hemoglobinopathies, enzymes and erythrocytic and cytogenetic membrane. Authors show relevant features of work developed in past years including researches of thalassemia allowing us to know the molecular bases of these hemoglobinopathies in our population. In the field of molecular biology initially we developed the Southern Blot technique; later, that of the polymerase chain reaction (PCR) and the inverse transcription, both very useful in the diagnosis and follow-up of patients presenting with malignant hemopathies. The presence of cytogenetic alterations (monosomies, trisomies, translocations, inversions and deletions) has been fully assessed in hematologic diseases and also with a great usefulness in the diagnosis, prognostic and follow-up of the patients. As regards the enzymopathies, it was possible to know the molecular alteration of variants lacking in glucose-6-phosphate dehydrogenase and with the development of the techniques for the study of proteins of erythrocytic membrane it was possible to determine the biochemical alteration of patients presenting with hereditary spherocytosis (HS).

Palabras clave : Hemoglobinopathies; molecular biology; cytogenetics; enzymopathies; membrane diseases.
