Trosolwyg

Ar ôl PhD mewn Bioleg Foleciwlaidd ym Mhrifysgol Caerdydd, dechreuais yrfa Ôl-ddoethurol yng Ngholeg Meddygaeth Prifysgol Cymru, gan ymchwilio i rôl Ffactor Twf Hepatocyte (HGF) ar endothelia. Arweiniodd hyn at y cyfle i archwilio HGF a'i wrthwynebydd NK4 mewn canser. Ers 1998, rwyf wedi bod yn ymwneud ag ymchwilio i rôl cyffyrdd tynn mewn canser (yn ystod metastasis) ac mewn endothelia (yn ystod angiogenesis). Mae fy niddordebau ymchwil yn cynnwys ymchwilio i sut y gellir modiwleiddio cyffyrdd tynn i reoli datgysylltiad a goresgyniad celloedd canser, ynghyd â diddordeb parhaus mewn ffactorau angiogenic a'u rôl mewn metastasis gyda diddordeb arbennig yn y mecanweithiau lle gall HGF reoli cynulliad cyffordd tynn a gweithredu mewn canser ac endothelia a rôl cyffyrdd tynn a metastasis ar draws rhwystr ymennydd y gwaed.

Cyffyrdd celloedd fel cyfryngwyr neu rwystrau i ledaenu celloedd a'r rheoleiddwyr ohono

  • Mae'r Cyffordd Dynn (TJ) yn rhanbarth lle mae pilen plasma celloedd cyfagos yn ffurfio cyfres o gysylltiadau sy'n ymddangos eu bod yn atal y gofod allgellog yn llwyr gan greu rhwystr rhynggellog a ffens trylediad intramembrane.
  • Mewn celloedd epithelaidd, mae'r TJ yn gweithredu mewn modd gludiog a gall atal datgysylltu celloedd tra bod TJs mewn celloedd endothelaidd yn gweithredu fel rhwystr lle gall moleciwlau a chelloedd llidiol basio.
  • Mae corff sylweddol o waith bellach yn bodoli ar TJ a'u rôl mewn nifer o glefydau.
  • Mae TJs wedi cael eu cydnabod fel chwaraewyr allweddol mewn metastasis canser. Awgrymodd astudiaethau cynnar fod cysylltiad rhwng lleihau proteinau TJ a gwahaniaethu tiwmorau a chynyddu tystiolaeth arbrofol wedi dod i'r amlwg i osod TJs yn y rheng flaen fel y strwythur y mae'n rhaid i gelloedd canser ei oresgyn er mwyn metastasize.
  • Mae rhyngweithio a threiddiad yr endotheliwm fasgwlaidd gan gelloedd canser datgysylltiol yn gam pwysig wrth ffurfio metastases canser.
  • Mae angen newidiadau mewn celloedd tiwmor ac endothelaidd ar gyfer twf a lledaeniad celloedd canser yn llwyddiannus a bod y newidiadau hyn ychydig yn debyg.
  • Mae newid mewn celloedd canser trwy uwchreoleiddio neu isreoleiddio proteinau TJ perthnasol yn arwain at golli cysylltiad celloedd-gell, atal cyswllt celloedd, gan arwain at dwf heb reolaeth, colli adlyniad i'r islawr a diraddio.
  • Rhaid i'r rhain fod yn golled gydamserol o gysylltiad cell-gell yn endotheliwm a modwleiddio proteinau TJ sy'n ymwneud â hwyluso hynt y celloedd canser trwy'r rhwystr hwn.
  • Rydym wedi dangos bod mynegiant gwahaniaethol o nifer o broteinau TJ trawsmembrane, yn enwedig Occludin, Claudin-5 a'r Nectin a'u bod yn cydberthyn ag aflonyddwch TJs mewn tiwmorau.
  • Mae modiwleiddio mynegiant o'r proteinau hyn yn arwain at newidiadau allweddol mewn swyddogaeth rhwystr gan arwain at ddilyniant canser a dilyniant metastasis.

Bywgraffiad

Career overview

Team Leader and Senior Lecturer: My research interests are investigating the role of Tight Junctions in the progression of cancer, and investigating how they can be modulated in both benign and pathological disease. I also have a continued interest in angiogenic factors and their role in metastasis. I supervise a large number of PhD, MD and visiting research fellows, attend national and international conferences (I have presented over 70 papers), write original research papers, reviews (many invited) and book chapters (invited). During the last 10 years, I was employed to work on 2 major projects as a research scientist: the first was sponsored by Abbot Pharmaceuticals (2003-2005) and involved investigating factors that could affect benign and malignant breast cancer cells in regards to cellular “leakiness”. This directly involved Tight Junctions as controllers.

2003 - 2020 Lecturer: Developing a research focau on Tight Junctions in cacner and metastatic disease. From 2006-2011 I was employed as the research scientist on a Cancer-Research Wales sponsored program grant. This involved the examination of Hepatocyte Growth Factor (HGF) and how this cytokine influences stem cells markers in breast and prostate cancer (funded by Cancer Research Wales). This work led to the award of the AACR-CTR-SABSC-Susan G, Komen for the Cure Scholarship for “Evaluation of the distribution of stem cell markers (PSCA, CD44, CD49b and CD133) in human breast cancer reveals correlation with clinical progression and metastatic disease in ductal carcinoma”.

March 2000 - July 2003 Research Fellow: Undertook a program of research to determine, using molecular, cellular and in vivo techniques, the mechanisms of cancer metastasis in particular the possible application of newly discovered antagonists to growth factors as an anti-metastasis tool (Susan G. Komen Breast Cancer Foundation for a study on 'NK4, a HGF/SF antagonist, as a new anti-metastatic-agent in breast cancer). This was followed by a project sponsored by CR-UK that involved the creation of an anti-metastasis/angiogenesis compound. I also began to research the role that Tight Junctions and their molecular constituents may have in breast cancer metastasis. This research was recognised at the 2002 San Antonio Breast Cancer Symposium, where I was honoured with a Astra-Zeneca Scholar Awards showing that tight junction molecules are lost in those patients with metastatic breast cancer.

June 1997- March 2000 Research Fellow: Establishing the role of fibroblasts in the process of tissue repair and cancer metastasis, identifying fibroblast derived factors responsible for the regulatory effect of fibroblasts, in the promotion of angiogenesis, at the Wound Healing Research Unit, University Department of Surgery at UWCM, Cardiff, UK for Prof. K.G. Harding (funded by Smith & Nephew/Advanced Tissue Science Joint Venture).
