Lab Safari



Join us for an opportunity to see exactly what
happens in a research laboratory. The Department
of Molecular and Cellular Therapeutics (MCT)
at RCSI is opening its doors for a science week
interactive tour. Visitors will get to interact with
high-profile scientists, explore our labs and
perform some hands-on science activities.
Anyone considering a career in science is
welcome but we particularly encourage young
women/girls to attend, to promote the full
participation of girls and women in science.

Introducing Ingmar Schoen

Hi everyone in MCT! Thanks for the warm welcome!
 As some of you know, I have joined RCSI as a StAR research lecturer in June. My plan is to establish a lab on ‘MechanoVascular Biology and Microscopy’. What do I mean by this?
 The first part ‘MechanoVascular Biology’ sets the scope. I am interested in how cells in the cardiovascular system use mechanical forces to achieve their tasks. As mechanical and chemical cell functions are tightly related, both play important roles in health and disease. Most research has focused on one or the other aspect, but not both. The novel research field of ‘mechanobiology’ takes an integrative approach to better understand how physical forces co-regulate chemical processes on the molecular level. In my previous work at ETH Zurich, I have studied how fibroblasts sense matrix stiffness and respond to it. Here at RCSI, I want to study platelets in the context of thrombosis and, over the years, investigate their interplay with endothelial cells.
The second part ‘Microscopy’ highlights one of the major working horses in my lab. Following the credo ‘seeing is believing’, watching cells can tell you a lot about how they do things. I use microscopy to test hypothesis but also to discover unexpected behaviour. Over the years, I have developed several new microscopy techniques to look at sub-second dynamic processes, directly measure cellular tractions, or determine the nanoscale architecture of multi-protein structures. These are great tools to better understand how the processes starting from platelet activation and ending with the consolidation of the thrombus are regulated in space and time. For this we will use in vitro models, but I am keen to move in the future towards in vivo imaging.
By now, you may have noticed from my scientific viewpoint and my enthusiasm for technology that my background is in physics. I studied physics with a specialization on biophysics at the Technical University Munich. My PhD work at the Max Planck Institute of Biochemistry focused on electrical stimulation of neurons with extracellular electrodes. After a short postdoc at the Ludwig Maximilians University Munich where I studied bi-molecular binding kinetics in living cells, I moved to ETH Zurich in Switzerland. That’s where I have started with mechanobiology and super-resolution fluorescence microscopy, which I know bring over to RCSI.
 A long way is lying ahead of me to cross the bridge towards clinical research. I look forward to having many inspiring discussions with you, already thank you for the ones we had so far, and hope that I can make a valuable contribution to the research here at RCSI!
Looking forward to seeing you at MCT Research Talks on 16th October 2017 at 12.00 TR4!
Kind wishes,

Timely Announcement for Nobel Prize


Last Monday while in Amsterdam with my Mam and two sisters, a friend of mine sent a text to let me know that the 2017 Nobel Laureates in Physiology and Medicine were Hall, Rosbash and Young.  They were awarded the Nobel for their work in identifying the key genes that create circadian or body clock rhythms in the fruit fly. My feet literally were stuck to the ground, it was thrilling to know that these gentlemen would get the recognition that they so deserve, but also what this will mean for the field of science that I am so passionate about. The body clock is the molecular timekeeping system that exists in practically every organism on the earth and in every cell in our body. Simply put, it allows the cell to tell what time of day it is. Why is that important? We live on a spinning planet and because of the earth’s rotation to the sun, all life on earth has been subjected to daily periods of light and heat, dark and cold. The body clock allows us to anticipate and respond to these 24-hour predictable environmental changes and synchronises our physiology to it. For example, the body clock increases cortisol levels in the body ahead of awakening, this helps us to become active once we wake. The body clock also increases expression of digestive enzymes in the intestinal tract during daylight hours (this is why curry chips at 3am is never a great idea!).

Back in the 80’s Hall, Rosbash and Young independently isolated a gene called Period, they showed how the gene encodes a protein PER that builds up in cells at night and degrades during the day. This daily rise and fall of PER essentially allow the cell to track time of day. How thrilling it must have been for them to observe this daily change in the mRNA levels of Period gene (Figure 1- black line), all that is changing along the x-axis is the time of day.

So what does this mean three decades later? We have made great strides in understanding how the molecular clock works. We now know that the clock keeps time by a series of transcriptional-translational feedback loops. We also know that the clock controls 40% of all coding genes within the body. The body clock controls all aspects of our physiology from metabolism to immunity.

Many diseases, such as osteoarthritis and cardiovascular disease, are highly time of day dependent. Moreover, it appears that disruption of our body clocks, caused by our non-stop 24/7 lifestyle and exposure to artificial light at all times of day, is partly responsible for the increase in chronic inflammatory diseases. Unfortunately, most cell culture systems are not synchronized with the time of day, and this, in my opinion, is one of the main reasons that many researchers unknowingly neglect this field. Finally, we are making great strides in attempting to time specific treatments to the right time of day, an area called chronotherapy. Therefore, it is my hope that this increased awareness of the body clock will bring more researchers into this fascinating field. If we don’t fully understand how our body clock controls physiology and disease we will certainly be left in the dark.

Annie Curtis is a Research Lecturer and runs the Immune Clock laboratory at MCT and is fascinated by all things body clock related.
