Molecular Cell Biology

Protein homeostasis is fundamental for cell function and survival because proteins are critical facilitators of  all cellular processes. Our goal is to better understand the processes that maintain the fine balance between newly synthesized and old or misfolded proteins, preserving the protein homeostasis and preventing various diseases. Current projects in the laboratory are focused therefore on  processes regulating protein lifetime:  protein  folding and maturation, trafficking, subcellular localization and degradation. Our research explores new ways of investigating the quality control process occurring in the endoplasmic reticulum that facilitates protein secretion towards the Golgi apparatus whilst regulating degradation  of misfolded proteins by ERAD pathways.

Protein processing with focus on antigen processing and presentation is currently investigated and aims at determining the exact role of ERAD components  in the generation of tyrosinase-derived tumour antigens.  Understanding of basic  mechanisms of antigen processing and presentation to T cells will provide valuable clues to enhance the efficacy of peptide-based cancer vaccines.  Deciphering the pathways mediated by the  tyrosinase-related antigen, TRP-2 is another focus of our group aiming at uncovering the potential implications of this antigen in the prognostic and therapy of malignant melanoma.

We develop new tools to extend our knowledge on the role of ERAD in the endoplasmic reticulum of secretory cells. Proinsulin matures in the  endoplasmic reticulum of  pancreatic β−cells and depending on the ER folding capacity is either secreted or destroyed. Our  hypothesis is  that up-regulation of ERAD enhancers may alleviate the ER burden in pancreatic β−cells by recruiting misfolded proteins for degradation. To verify this hypothesis we use model β−cells, intact primary  islets and animal models with modified ERAD and test the insulin secretion upon glucose-stimulation.

In the next years our research will focus on the molecular mechanisms of the folding and intracellular transport of soluble and membrane bound glycoproteins. In particular, melanoma proteins will be investigated in terms of  maturation, degradation and antigen presentation.

Director of Institute, Head of Department

Dr. Petrescu graduated from the Department of Biochemistry, University of Bucharest and obtained a PhD in Biology from the Romanian Academy. She was a DAAD fellow and FEBS fellowship recipient at University of Wurzburg, Germany, during 1990. She followed postdoctoral studies in the Department of Biochemistry at the University of Oxford, UK. She obtained three consecutive Wellcome Trust Grants in collaboration with the University of Oxford from 1995- 2004. She investigated the glycobiology of tyrosinase from melanoma cells contributing to the fundamental mechanisms of calnexin associated folding and quality control of glycoproteins. She proposed tyrosinase as More...

In vitro evaluation of potential biomedical strategies aimed to prevent bone loss during spaceflight 2017-2019
Acronym: SPACEBONE
Project director: Stefana-Maria Petrescu

Bone loss represents one of the most important health problems experienced by Space travelling astronauts. Microgravity produces deterioration of the skeleton due to lack of mechanical loading thus affecting both muscle and bones. Tendons stiffness decreases, muscle fibres atrophies and attenuates their metabolic capacity, whileprogressive cartilage loss occurs.
