Bayer announced awards of $2 Million in Hemophilia Research and Patient-care Grants to 16 People at The International Society on Thrombosis and Haemostasis 2017, held in Berlin in July.
Congratulations to Dr. Roger Preston, Irish Centre for Vascular Biology[ICVB], (MCT) who was awarded a prestigious Special Project Award (€200,000) from the Bayer Haemophilia Award Programme to develop novel pro-hemostatic agents for the enhanced treatment of patients with haemophilia.
There was a strong representation from MCT at the ISTH Congress including Professor Dermot Kenny, Professor James O’Donnell, Dr. Roger Preston and their respective teams, and Dr. Dermot Cox, President, SSC* 2018. [*SSC:The Scientific and Standardization Committee].
Orla Willis Fox, Phd student with Dr. Roger Preston (ICVB/MCT), was awarded an ISTH Young Investigator Award for submitting one of the highest ranked abstracts. Her abstract title was ‘Inhibition of Activated Protein C Aspartyl Beta-hydroxylation Restricts Anticoagulant Function but Enhances Cytoprotective Signaling Activity’.
Professor James O’Donnell, ICVB/MCT presented an invited state-of-the-art lecture on his landmark studies on VWF and Cerebral Malaria,Dr. Michelle Lavin, ICVB/MCT on LOVIC [The Low Von Willebrand factor Ireland Cohort (LoVIC)] study, Dr. Sonia Agulia, ICVB/MCT on The Role of Sialylation in low VWF levels andSoracha Ward, ICVB/MCT gave a presentation on VWF Clearance.
Additionally, there was significant interest among the attendees in the ISTH SSC 2018 Annual Meeting which will be held in Dublin 2018; Dr. Dermot Cox, President, SSC 2018 anticipates a record attendance of 3,000 delegates for the Dublin meeting. Olwen Foley , (MCT) managed the Irish stand.
Over the last 10 years, Prof Tracy Robson has collaborated closely with Almac Discovery on the development of the therapeutic peptide, ALM201, based on her initial research into the anti-angiogenic properties of FKBPL. ALM201 is part of the active anti-angiogenic domain of FKBPL and is a potent inhibitor of angiogenesis both in vitro and in vivo. The technology was patented by Professor Robson and licensed to Almac Discovery. Following collaborative pre-clinical work showing robust efficacy, this ‘first-in-class’ FKBPL-based antiangiogenic peptide has entered phase I/II clinical trials in the ovarian setting (EudraCT No: 2014-001175-31). Whilst the trial is ongoing, we have received exciting news that the U.S. Food and Drug Administration (FDA) has granted Orphan Drug Designation to the drug candidate ALM201 in the treatment of ovarian cancer. The FDA Office grants orphan drug designation to encourage the development of drugs for the prevention, or treatment of a medical condition affecting fewer than 200,000 people in the US and grants market exclusivity for a seven-year period if the sponsor complies with certain FDA specifications. Receiving Orphan Drug Designation for ovarian cancer underlines the fact that ALM201 may address a significant unmet medical need for this important disease.
While RCSI is an institution with a long-standing international perspective on education in the health sciences, it has as a strategic goal the further extension of its international activities, particularly in relation to research collaborations. RCSI is doing so through several mechanisms, which include Science Foundation Ireland International Strategic Collaboration Awards (ISCAs), namely ISCA-Brazil, ISCA-China and ISCA-Japan, awards from the Japan Society for the Promotion of Science (JSPS), the EU Erasmus+ programme, and via joint programmes with individual institutions. Over the past several years, I’ve been pleased to contribute to these developments and continue to do so in my new role as Professor Emeritus.
In October-November 2016, I spent three weeks in Japan under a JSPS Invitation Fellowship. From a base at Hoshi Pharmaceutical University, Tokyo, I also visited and gave seminars at Nihon University at its Tokyo and Matsudo campuses, Nagoya University, and Takeda Pharmaceutical Company, Fujisawa. Even after many previous visits to Japan, it’s difficult to describe the enduring professional and personal pleasures of interacting and fostering collaborations with Japanese academics/scientists and enjoying their beautiful country and so hospitable a culture and society. In addition to ongoing research collaborations with Prof. Hiroko Ikeda and her colleagues, this summer will see the second exchange of RCSI and Hoshi University students to participate in the International Research Summer School, directed in RCSI by Dr. Sarah O’Neill (MCT), whereby up to four students from each Institution travel to the other to undertake a 2-month research project. Additionally, later this year Dr. Sudipto Das (MCT) will travel to Hoshi University under a JSPS Postdoctoral Fellowship to further extend collaborative research studies. We hope that such interactions will grow over the years to come.
In February-March 2017, I spent three weeks in China under a joint appointment as a Professor of Pharmacology in the College of Pharmaceutical Sciences at Soochow University, approximately 100 km west of Shanghai. China is a country that is now pursuing a ‘twin-track’ approach of “… internal restructuring of its economy combined with exposure to global trade winds and investment”. While this presents some similarities but many fascinating contrasts with academe in both Japan and Ireland, interacting and fostering collaborations with Chinese academics/scientists also brings many professional and personal pleasures. While there, I gave three undergraduate lectures on mental health, met with postgraduate students and postdoctoral researchers, and facilitated the visits of Prof. Tracy Robson & Dr. Darran O’Connor (MCT), Prof. Jochen Prehn (Physiology & Medical Physics) and Prof. Brian Kirby (School of Pharmacy) to Soochow University and the subsequent reciprocal visits of Profs. Xinliang Mao and Xinchen Teng to RCSI. In addition to ongoing research collaborations with Prof. Xuechu Zhen, this summer will see the third exchange of RCSI and Soochow University students to participate in the International Research Summer School, whereby, as with Hoshi University, up to four students from each Institution travel to the other to undertake a 2-month research project. Dr. Darren Griffith (Pharmaceutical & Medicinal Chemistry) will be the next RCSI colleague to visit Soochow University and we hope that such interactions, like those with Hoshi University, will grow over the years to come.
It is difficult to think of a greater contrast than my recent visit, April 2017 under Erasmus+ funding, to Novosibirsk State University and the Institute of Physiology and Fundamental Medicine. Novosibirsk is Russia’s third-largest city and is located in Siberia, approximately 2,800 km east of Moscow. The University and Research Institutes are located in Akademgorodok [Akadem = academic, gorod = town, ok = small, hence Akademgorodok = small academic town], the purpose-built educational and scientific centre of Siberia constructed in the late 1950s approximately 30 km south of the city of Novosibirsk. In April, there was still some snow on the ground and the nearby Ob river was still frozen and will remain so until the end of May. During my stay there, the weather ranged from one blizzard and one (in their terms) ‘regular’ fall of snow through to warm, sunny periods with a temperature of 20C; Prof. Marc Devocelle (Pharmaceutical & Medicinal Chemistry) and I were reluctant to travel to Novosibirsk until April, to avoid the harsh Siberian winter, a meteorological objective that was only partially successful. This academic centre has both original and new buildings, with good teaching and research facilities. Under the kind offices of Profs. Vladimir Pustylnyaki and Michele Debrenne, Novosibirsk State University, I gave three undergraduate lectures on the neuroscience of mental health, and under the auspices of Dr. Tatiana Lipina, Institute of Physiology and Fundamental Medicine gave a postgraduate seminar.
Meetings with them and several other colleagues explored the potential for future research collaborations. After what we regarded as a good meeting, one colleague reached into a cupboard for a bottle of vodka and poured us each a generous measure; he hoped this would induce ’emotional warmth’ commensurate with what he regarded as the positivity of the meeting. After this had been imbibed, he then poured a second generous measure of vodka, to reinforce these positive sentiments. Clearly, RCSI needs to reconsider its policies in this regard with a view to appropriately realigning its practices to these new international standards. As I write this in the second week of May, Prof. Konstantin Volcho, Dr. Ekaterina Semenova and Dr. Artyom Rogachev are currently making reciprocal visits to RCSI under Erasmus+ funding and we hope that such interactions, like those with Hoshi and Soochow Universities, will grow over the years to come.

She was awarded a prestigious L’Oréal-UNESCO For Women in Science 2017 Fellowship at a ceremony held at the Royal Society in London on May 5th.
She was one of five winners of these fellowships and the only Irish winner this year. The fellowship will support her research into understanding the precise mechanisms by which the body clock restrains inflammation from a key immune cell called the macrophage.
The main challenge in treating high-risk neuroblastoma is to combat tumour metastasis and development of resistance to multiple chemotherapeutic drugs. In the native tissue, cancer cells are surrounded by a three-dimensional (3D) microenvironment which provides biological and physical support and determines disease initiation, progression, patient prognosis and response to treatment. The conventional two-dimensional (2D) cell culture lacks this feature resulting in discrepancies between in vitro and in vivo results. Current neuroblastoma studies employ either 2D cell culture systems or murine models or alternatively a mix of both.
In collaboration with Dr Caroline Curtin and Prof Fergal O’Biren (TERG), we decided to bridge the gap between 2D culture and in vivo tumours in neuroblastoma research by developing a tissue-engineered cell culture model of neuroblastoma. This project is supported by a pilot grant from Neuroblastoma UK.
To understand what signalling pathways are activated in 2D, 3D and in vivo neuroblastoma models, we decided to look closer at the differences between conventional 2D neuroblastoma cells and their xenografts. This way we hope to find those targets that are activated in both tumour microenvironment and the 3D tissue engineered models. Ciara and Larissa have begun this search by profiling xenograft samples with a panel of antibodies. Ciara became particularly fascinated by the elevated levels of c-jun, TCF1 and LEF1 in cisplatin-resistant neuroblastoma xenografts suggesting that the development of cisplatin resistance in neuroblastoma may be accompanied by activation of the wnt/b-catenin pathway in vivo. Larissa identified that cisplatin-resistant neuroblastoma cells secrete chromogranin A (CgA) at levels higher that cisplatin-sensitive cells. CgA levels also correlated with increased vascularisation and volume of murine orthotopic neuroblastoma xenografts. Altogether it suggests that CgA can be used as a marker of neuroblastoma cell growth both in vitro and in vivo.
Following a workshop conducted at Hoshi University, Tokyo, Japan organized through the ISCA-Japan initiative funded by SFI in October, 2015 a successful collaborative initiative was established between Dr. Sudipto Das (MCT, RCSI) and Prof. Hiroko Ikeda (Department of Neurophysiology, Hoshi University) to investigate the role of epigenetic modifications like DNA methylation in driving a neuronal dysfunction phenotype associated with Diabetes mellitus (DM). Moving this collaboration forward with support from his collaborators at Hoshi University Dr. Sudipto Das has recently received a prestigious short-term post-doctoral fellowship to further his work at Hoshi University from the Japan Society for Promotion of Science (JSPS), which would essentially cover travel, subsistence and a research consumable allowance of 562,000 Japanese Yen. As a part of this fellowship, Dr. Das will travel to Japan for a period of 1.5 months in January 2018. The successful completion of the proposed project as a part of this proposal will for the first time allow the scientific community to understand as to how epigenetic modifications like DNA methylation impact on neurological dysfunction in endocrine
The successful completion of the proposed project as a part of this proposal will for the first time allow the scientific community to understand as to how epigenetic modifications like DNA methylation impact on neurological dysfunction in endocrine related disorders such as DM, thus opening up avenues to utilize this modification to potentially predict such conditions in DM patients.
Asthma is of particular relevance to the area of circadian control of immunity, since it is a disease with very strong clinical evidence demonstrating regulation by circadian variation. Airway hypersensitivity and asthma attacks are more common at night in humans. The molecular basis for this is unknown and no model of asthma in animals with genetic distortion of the molecular clock exists.
In this study, we showed that mice lacking the main clock transcription factor BMAL1 in myeloid cells have increased lung inflammation demonstrated by higher numbers of eosinophils and increased IL-5 (key pathogenic cytokine in asthma that recruits eosinophils).This suggests that Bmal1 is a potent negative regulator, in myeloid cells in the context of allergic asthma. Our findings might explain the increase in asthma incidents during the night in humans when BMAL1 expression is low.
Prof Tracy Robson (MCT), Prof Jochen Prehn (Physiology & Medical Physics) and Dr Darran O’Connor (MCT) have recently returned from 1 week at the College of Pharmaceutical Sciences, Soochow University, Suzhou, China where they participated in a workshop with faculty to explore research collaborations and future joint funding applications under the newly announced SFI-NSF Partnerships for International Research and Education. Supported by an Erasmus+ programme coordinated by Prof Marc Devocelle (Department of Pharmaceutical and Medicinal Chemistry), the workshop involved presentations from RCSI and Soochow investigators describing their work and discussion to identify areas of synergy. Afternoon lectures by RCSI faculty were opened to postgraduate and postdoctoral researchers from Soochow, leading to a vigorous and stimulating discussion and Prof Xinliang Mao from Soochow will visit RCSI next month to further strengthen future collaborative research opportunities.
At the invitation of the President of the British Pharmacological Society, Professor John Waddington (Emeritus, RCSI) has been elected to Fellowship of the Society; this is in recognition of his career contributions to research, education and service in the discipline of pharmacology, not just in Ireland but globally. He has recently returned from 3 weeks at the College of Pharmaceutical Sciences, Soochow University, China, under his joint appointment as a Professor of Pharmacology. While there, he continued collaborative research, gave undergraduate lectures and fostered further joint endeavours between RCSI and Soochow University, which is in the top 5% of Chinese research universities.

Epilepsy is a common neurological disorder that affects ~40,000 people in Ireland. There are many different types of seizures which are caused by uncontrolled electrical impulses in the brain. Anti-epileptic drugs control seizures for ~50% of people with epilepsy but up to ~30% of patients remain uncontrolled despite treatment with multiple drugs. Epilepsy is caused by a number of factors include stroke, trauma and infections. However, more recently we have learned that epilepsy can be caused by genetic mutations. Some epilepsies are heritable while others arise de-novo. Many patients with an intellectual disability (ID) also have epilepsy. Many of these patients lack a specific diagnosis due to limited testing and available investigations. We sequenced a cohort of 99 adult patients with epilepsy and ID on a custom gene panel of ~150 genes. A likely pathogenic variant was identified in 20 patients in 19 different genes, including SCN1A, DCX and DEPDC5, well-known epilepsy genes. Furthermore, we identified copy number variants in two patients which are likely causative. Further work is needed to investigate the phenotype-genotype correlations identified in this study and any potential treatment options that may arise.
