Research profile

There is evidence of overlapping issues in the biology of aging and the biology of cancer on organismal as well as cellular levels. The major interest is biogerontology and biology of cancer focused on the understanding the molecular mechanisms regulating cell proliferation, cellular senescence and cell death.

Current research activities

  • Studies on the immunosenescence focused on searching for immunological markers (T cell phenotypes, propensity to undergo apoptosis and proliferation capacity) possibly determining healthy aging and longevity.
  • Searching for the longevity genes in the frame of FP6 GEHA-genetics for healthy aging coordinated by Prof. Claudio Franceschi;
  • Studies on cellular senescence in vivo and in vitro elucidating mechanisms of cell cycle regulation and proliferation cessation, telomere erosion, functional activities and cell capacity to undergo apoptosis;
  • Investigation of molecular mechanisms leading to cancer senescence induced by low doses of DNA damaging agents and Curcumin, a natural polyphenol derived from Curcuma longa; cancer cell senescence as a potential anticancer strategy;
  • Investigation of the Bcr-Abl-dependent pro-survival and antiapoptotic pathways with particular interest in the role of p53, GSK-3beta kinase, Bcl-2 family proteins and endoplasmic reticulum stress. Studies on mitosis and spindle assembly checkpoint regulation in Bcr-Abl expressing cells; the possible connection with genomic instability in leukaemic cells;
  • Studies on apoptosis resistance of cancer cells and mechanisms of cell death types alternative to apoptosis with particular interest in mitotic catastrophe; Curcumin, as a potent inducer of various types of cell death;
  • Studies on activation of Akt/PKB and ERK ½ kinases and their possible participation in down regulation of ornithine decarboxylase expression induced via cell membrane receptor c-Met and androgen receptor in mouse kidney;
