Awards & Achievements
Our overarching goals are to discover key aspects of ovarian development that underpin our understanding of infertility and endocrine diseases involving the ovary, and to develop prevention and treatment strategies for these. My group, in collaboration with many others, focuses on the roles of extracellular matrix. Matrix is diverse and complex and regulates many cellular and tissue functions. It has been largely overlooked in comparison with the numerous studies of hormones and growth factors in the ovary and hence holds potential for many new discoveries.
- Mechanism of Fetal Predisposition
to Polycystic Ovary Syndrome: While the precise aetiology of PCOS is yet to be determined,
several familial studies from others have demonstrated an association
between PCOS and the dinucleotide repeat microsatellite marker D19S884.
D19S884 is located within intron 55 of the extracellular matrix gene
fibrillin 3 gene. Studies of fibrillins 1 and 2 have shown that they
function both as structural components of elastin fibres or mircrofibrils
and as regulators of TGFβ family members. Regulation of TGFβ activity by
fibrillins is a result of their ability to bind to latent TGFβ binding
proteins causing sequestration of latent TGFβs into the extracellular
matrix where they are stored and/or activated. TGFβs stimulate collagen
production by fibroblasts and are up regulated in fibrosis. The PCOS ovary
has increased trunica albunigea and stroma and collagen deposition in
these layers. We published two large studies by Ray Rodgers (Molec
Cell Endo 307, 133; Molec Human Reprod 15, 829) where we failed to find
any role of fibrillin 3 in adult ovaries. Then in a landmark study we showed that fibrillin
3 was found to be expressed in the developing stroma of human and bovine
fetal ovaries (FASEB J 25, 2256-2265).
This study mechanistically combined three important observations
about PCOS: (a) The fetal origins of PCOS, (b) The genetic studies
suggesting that fibrillin 3 could be a candidate gene in PCOS and (c) The
PCOS ovarian phenotype with altered stromal compartments (tunica
albuginea, cortical stroma, theca interna); the hallmarks of enhanced TGFβ
activity. Note that this is also
the first time TGFβ had been implicate in the aetiology of PCOS.
- Formation of the Ovary: The
continued study of PCOS necessitated studying the fetal ovary. It soon became clear the current
hypotheses on how the ovary develops, and as described in anatomy text
books are not correct. We
identified how the ovary and follicles develop during fetal development (PLOS
ONE 8(2):e55578). Importantly we
identified a novel cell type, GREL (Gonadal-Ridge Epithelial Like) cells,
that are the precursor cells of both the surface of the ovary and the
follicular granulosa cells. We
identified the surface epithelium at the base of the ovary differs in its
developmental origins that the rest of the ovary, perhaps explaining the
difference in their stemness and oncogenic potential observed between
these two regions of the ovary surface (Nature.
- Regulation of Thecal Androgen
Production: Androgen production
by the theca cells is the cause of hyperandrogenia in PCOS women. A hormone INSL3 whose role was not
understood is also expressed in the thecal cells. Early studies by us and collaborators (Biol.
Reprod. 66, 934-943) found it be dynamically regulated during follicular
growth and atresia. In
collaboration with Prof Phil Knight of Reading University is has now been
shown to be regulated by BMPs and to stimulate androgen production by the
thecal cells (Proc Natl Acad Sci USA
110, doi =10.1073/pnas.1222216110).
- Oocyte Quality: Whilst studying the follicular basal laminas
we discovered in bovine (J. Reprod. Fertil. 118, 221-228) and in humans (Human Reprod. 24, 936-944) that follicles have one of either of two phenotypes of follicular
basal lamina. We believe these are formed
by differential rates of follicle antrum expansion (Biol Reprod 82, 1021–1029). These forms are related to the quality of
oocytes within them based upon their ability to mature in vitro (Human Reprod. 24, 936-944). Both follicles are
healthy. Using a combination of microarrays, proteomics and metabolomics
we are identifying molecules differentially present in these follicles
that could be used as biomarkers for each follicle type. Significant
savings and improvements in ART should be possible if we could choose the
better embryos for uterine transfer in IVF programs, thus increasing
- Focimatrix and Maturation of Follicles: We have identified many components of matrix
and the changes they undergo in developing follicles, atretic follicles,
ovulating follicles and resultant corpora lutea. We also identified a
novel type of basal lamina matrix, called focimatrix, which is
developmentally regulated in the later phases of follicular growth (Matrix Biol. 23, 207-217.). The novel aspect of this matrix is its
conformation. Basal laminas are normally a sheet of matrix ‘wrapped'
around a cell or a group of cells (epithelia or endothelia). Therefore
basal laminas make compartments within tissues. Focimatrix, however, does
not form a continuous layer and thus it cannot perform known basal lamina
functions. Our recent data suggest that focimatrix is the key to a
follicle developing dominance over other follicles in the follicular phase
of the cycle (Mol Cell Endo 321,
207-214; Reproduction 137, 825-834). Studies into its regulation and function
maybe useful in improving fertility both in PCOS women and in IVF
- Formation of Follicular Fluid: Growth of the follicle encompasses
enlargement of the oocyte, replication of follicular cells and formation
and expansion of a central follicular antrum or cavity. Many in vitro
studies of follicular growth have focused on the replication of granulosa
cells, whilst in vivo studies using ultrasonography have focused on the
expansion of the follicular antrum and its fluid. Replication of
follicular cells and expansion of the follicular antrum are both
important, and both are probably stimulated by some of the same hormones
and growth factors. They are, however, very distinct processes. Our
central hypothesis on follicular fluid formation, which is based upon our
data, suggests that production by granulosa cells of hyaluronan and the
chondroitin sulfate proteoglycan versican generate an osmotic gradient to
draw in fluid from the thecal layer (Reproduction 132, 119-131; Biol Reprod 82, 1021–1029).
