MD, PhD, Professor emer.
Hormone-regulated cancer, selective estrogen receptor modulators (SERM), in vitro and in vivo models for breast and prostate cancer
Pirkko Härkönen
graduated in medicine and received her PhD degree in experimental endocrinology
at the University of Turku. She worked as postdoctoral fellow at the Imperial
Cancer Research Fund (now Cancer Research UK), in London, UK (1985-1987). Since
postdoctoral training, she worked in various positions at the Department of
Anatomy, University of Turku and as Senior Researcher of Academy of Finland
(1994-2000). In 2002, she received a position as Professor of Tumor Biology at
Lund University, Sweden, and in 2010 as Professor of Medical Cell Biology at
University of Turku. She also worked as Head of the Institute of Biomedicine
(2010-2016). She retired from professor’s position in 2016 and presently works
as researcher and senior specialist at the Institute of Biomedicine.
The research of
Dr Härkönen has concerned growth mechanisms of human breast and prostate cancer
using experimental in vivo and in vitro models and clinical tumor specimens. Recently,
her group has concentrated on patient-derived models of breast and prostate
cancer. She has particularly focused on the FGF/FGFR mediated tumor growth, progression
and metastasis and the role of the FGF/FGFR pathways in hormonal regulation and
development of hormone resistance. Prof.
Härkönen has published more than 140 original research papers and she has
supervised 21 completed doctoral theses. She has extensive experience in
teaching students in the Medical and Dental curricula as well as in the
Bachelor`s program and the International Master`s Degree program in the
Biomedical Sciences. Besides several positions of trust, she was the first
director of the National Drug Discovery Graduate School. She is a founding
member of a drug discovery company and two contract research service companies
(CROs). Her research group has critically contributed to discovery process of a
drug now in clinical use (Osphena) and transfer of clinically relevant disease
models to local spin-off companies.
We study the role of the fibroblast growth factor (FGF)/FGF receptor
(FGFR) pathways in regulation of the growth, progression and metastasis in breast and prostate cancer using
experimental cell and tumor models, and clinical tumor specimens. Particular attention is paid to the role of FGF/FGFR pathways in hormonal regulation and development of endocrine resistance in breast and prostate cancer.
To develop new diagnostic methods, the
applicability of tumor-specific glycoproteins on breast and prostate cancer
cells as targets for novel molecularly imprinted synthetic probes is studied.
To obtain tools for finding and testing personalized
treatments, we work to establish patient-derived in vitro and in vivo breast
and prostate cancer models, including 2D and 3D cell cultures, explant cultures,
and tumor and metastasis models.
