Here is the perfect example of the teamwork troubleshooting protein extractions. My Dream Team 2018 in action. The current information and communication technologies allow to stay connected and respond quickly.
Five minutes later in the lab: troubleshooting is the exchange of experiences!
When I look back on my journey in 2017, there were many junctions, traffic lights and stops as well as ups and downs. Junctions were to make decisions, while traffic lights and stops – to be patient. Ups and downs were my feelings of satisfaction. The good mix of both kept me to stay human. It is not the number of grants received that matters it is who around you. I have met genuinely curiosity-driven students who made this journey fascinating and very special.
My most memorable Ups were the successful examination and graduation of my PhD student John Nolan, organisation and chairing the IACR Meeting session: Challenges in Childhood Cancers, the Mad Hatter’s Tea Party and the Gala Dinner with the CFNCRF, the launch of my very own research team thanks to the funding by the NCRC and the Neuroblastoma UK, the successful completion of two final year undergraduate and two MSc projects, and welcoming the new PhD student Tom Frawley.
My team is growing and I am looking forward to 2018!
On November 20th, the Irish neuroblastoma researchers have met for the first time to set up a collaborative research hub. The aim is to consolidate their expertise and skills in order to crack the neuroblastoma code together.
They all have different science background spanning from molecular and cellular biologists, immunologists, tissue-engineering, bioinformatics, mathematical modelling and clinicians representing RCSI, UCD, TCD, OLCHC and NCRC. During this meeting, researchers talked about their challenges and progress finding out that we are complementing each other projects. Clinicians from different OLCHC departments exposed basic researchers to realities of the disease. None would find this information in academic papers: it is what you see in the clinic and how it works in practice.
Big thank you to Dr Cormac Owens for the invitation and linking us together and Prof Jacinta Kelly for mapping the support available from the NCRC and CMRF.
Our next meeting will be held in RCSI in January 2018.
Happy Birthday the Irish Neuroblastoma Research Consortium!
It is always a pleasure to host undergraduate students during summer months. Two students joined the RCSI Research Summer School (RSS) Programme. Both are working on the NCRC funded project to understand mechanisms that drive neuroblastoma pathogenesis. None of them had a prior lab experience, but nothing is impossible under John’s supervision.
A full concentration on every single step of the research.
The research is a long-term investment. It is always built up on the work of the predecessors. Keep research running is crucial to make the dreams come true. Dreams for better treatment options and quality of life.
Thank you to everyone involved in raising funds for CMRF!
The ultimate aim is to identify biomarkers of tumour response to drugs in the blood of children with high-risk neuroblastoma.
Challenge: Treatment regimens for patients with high-risk neuroblastoma involve intensive, multi-modal chemotherapy. Many patients response to initial therapy very well, but has only short-term effects, with most becoming resistant to treatment and developing progressive disease.
The project has two parts which complement each other.
We will study cell-to-cell communication using cell-based models. We will collect exosomes, small envelopes containing bioactive molecules, produced by drug-resistant cell lines to treat non-cancerous cells. We will measure the effect of exosomes on non-cancerous cells by counting cell growth, examining their shape and metabolism. We will also examine whether non-cancerous cells treated with exosomes become less responsive to chemo drugs.
We will treat neuroblastoma cells with a drug and collect exosomes before and after treatment. We will profile exosomes to identify any changes in their miRNA content. MiRNA are very small pieces of genetic material that can change the way cell feels and works. This step will help to find biologically active miRNA that can trigger cell resistance to drugs. These biologically active miRNA can represent biomarkers of tumour response to chemotherapy.
We will screen clinical samples for exosomal miRNA in response to drug treatment. We are planning to use a small sample of blood taken from neuroblastoma patients during routine examinations before, during and after chemotherapy.This step will help to find clinically relevant miRNA of tumour responsiveness to chemo drugs.
How does this project contribute to the biomedical community?
This study aims to contribute to the better understanding of the disease mechanisms and scientific knowledge in the area, and in particular how neuroblastoma cells communicate with other cells helping tumour to create a unique microenvironment and protect themselves from chemotherapy pressure. The new data will give insights in biologically active proteins and miRNAs involved in cell-to-cell communication and drug responsiveness.
What are potential benefits of the proposed research to neuroblastoma patients?
This project aims to develop exosomal biomarkers of tumour response to drugs that might be used to help select patients for treatment and identify novel targets for the development of more effective personalised therapy with the anticipated improvement in outcomes. This work will contribute to the more efficient design of re-initiation treatment, sparing patients unnecessary rounds of chemotherapy and ultimately increasing survival. These new circulating markers will benefit children with high-risk neuroblastoma whose tumours are relapsed leading to less harmful and more tailored treatment options and improving their quality of life.
