Biography

Gabriela Chiritoiu graduated from Faculty of Chemistry, University of Bucharest (2004-2008). She received her Ph.D. in Biology from the Institute of Biochemistry of the Romanian Academy in 2016, under the supervision of dr. Stefana Petrescu and her thesis was focused on investigating the role of glycosylation and ERAD (endoplasmic reticulum associated degradation) in epitope generation and antigen presentation.

Microfluidic assay of FGF2 therapeutic administration for bone regeneration 2017-2019
Acronym: μFGF2bone
Project director: Gabriela Chiritoiu

Musculoskeletal disorders affect 1 in 7 people and fractures alone affect 1 in 50 people annually while 10% of bone injuries fail to heal. Our present proposal aims to test for the first time the potential of fibroblast growth factor-2 (FGF2), to be administered as a stimulatory drug to enhance bone regeneration.

Role of TG2 in cancer tumor microenvironment for guiding metastasis prevention therapeutic approaches 2020-2022
Acronym: TG2TARGET
Budget: 431,900 RON
Project director: Livia Sima

The overall goal of the current project is to understand the impact of tissue transglutaminase (TG2) targeting in the context of ovarian cancer (OC) tumor microenvironment (TME). Our aproach is aimed at testing the hypothesis that interventions in targeting TG2 in the OC TME will disrupt pro-tumorigenic signaling cross-talk within tumors.

Context-dependent therapeutic targeting of ovarian cancer metastasis using TG2 small molecule inhibitors 2020-2022
Acronym: TG2THERAPY
Budget: 600,000 RON
Project director: Livia Sima

The principal goal of this project is the development of a new class of small molecule inhibitors (SMIs) targeting TG2-FN interaction, which is currently in the phase of lead optimization, translatable to clinical use for prevention of ovarian cancer dissemination, either alone or in combinations.

Identification of new molecules involved in melanoma associated antigens production 2020-2022
Acronym: ImmunoMOD
Budget: 246,950 RON
Project director: Gabriela Chiritoiu

This project aims to develop new strategies to improve the capacity of antigen presenting tumor cells to activate cytotoxic T cells and hamper immune escape mechanisms in cancer.

IDENTIFICATION OF IL-1Β CYTOKINE SECRETION MODULATORS TARGETED BY REPOSITIONED DRUGS 2023-2025
Acronym: RepozIL
Budget: 200.000 RON
