#IamFulbright – Blog about neuroblastoma research

How things work in science: targeting cell components.

How do researchers study cells? How do we get the nitty gritty?

We use many methods to tag and chase various cell components. One of my favourites is fluorescent microscopy. It allows the use of nearly all spectrum of colours from blue to purple in one go. However, we prefer to narrow it down to 2-3 colours and avoid their overlap.

How does it work? First, we use DAPI or Hoescht, which are blue fluorescent dyes used to stain DNA. This way, we tag the nucleus of the cell. Then, we tag a protein of interest. In our case, it was MYCN, a protein that acts as a transcription factor. MYCN amplification is associated with poor prognosis in neuroblastoma. As a transcription factor, it binds to genomic DNA and is located in the nucleus. We used a specific antibody that was labelled with a green fluorescent dye. Look at the image below. The green colour pattern overlaps with the blue colour. Then, we tagged the cytoskeleton, a complex of various proteins that hold the cell architecture and dynamics. We used phalloidin with red fluorescence. It is a highly selective bicyclic peptide and a popular choice for staining actin filaments.

Now, we can enjoy visualising cells and test different research questions. For example, how do cells respond to a drug? Or how do neuroblastoma cells spread?

How things work in Science: Tìr na nÒg

In humans, NANOG, SOX2, and OCT4 are transcription factors that maintain the undifferentiated state of embryonic stem cells (ESCs). NANOG was first discovered in 2003 by Chambers et al. and Mitsui et al. as a transcription factor in ESCs responsible for cellular self-renewal. More importantly, it enables continuous self-renewal of cancer stem cells, leading to metastasis when the regulatory genes involved do not function normally. These have been identified as cancer stem cells, with NANOG being a marker of “stemness”. In multiple cancer types, NANOG has various effects, including cellular expression of mesenchymal phenotype, cellular invasion/migration, repressed apoptosis, drug resistance, and increased angiogenesis. In pathways, NANOG either promotes or represses the expression of other genes that lead to cancer-favoured cellular behaviour. Overall, a higher expression level of NANOG is usually indicated in cases of poor prognosis.

NANOG is even more interesting due to its eponym, which comes from Tìr na nÒg. A Celtic myth of the Land of Youth, where the Tuath Dé resided in a supernatural land of paradise. This land offered beauty, health, joy, and everlasting youth to the inhabitants. As the myth goes, the Tuath Dé were gods of the land, and the god that ruled, Manannán mac Lir, was the first ancestor of humans. In various Celtic legends, humans are invited by the gods to visit Tìr na nÒg on great adventures.

However, time passes much slower in Tìr na nÒg, making it precarious for humans to return to their own world. As is the fateful tale of Oisín, who fell in love with the Tìr na nÒg goddess, Niamh. He travelled with her to Tìr na nÒg, where they lived happily in paradise. Upon a visit back to Ireland, Oisín realized that all his family had died over the years. When Oisín found a group of men who were struggling to move a giant rock, he stopped to lend them a hand while on his horse. However, the weight of the rock caused his saddle strap to snap. He fell from his horse, and when he touched the ground, he suddenly aged 300 years all at once.

New Orlean’s Red Beans & Rice

While completing my Master’s degree at Tulane University in New Orleans, Louisiana, I found the top-notch post-grad comfort food I’ve taken with me ever since. After a day of work, the last thing I want to do is come home and cook an entire meal. Luckily, red beans and rice can be adapted to a slow cooker. Allowing me to throw all my ingredients in and come home to an amazing-smelling apartment with the most satisfying warm bowl waiting for me.

There’s something to the name “The Big Easy” that describes New Orleans because the people and the food take life a bit slower and enjoy every savoury bit together. My favourite memory in New Orleans is when my friends and I prepped a massive stock of red beans and rice for the week of Mardi Gras. This is an entire week of festivities and parade floats where the city quite literally shuts down since everyone participates. It was so comforting every night (or early morning) to come back from the parades and dish out the prepped meal that would fill you up, stick to your bones, and help you fall sound asleep with more than enough energy for the next days of parades.

*My first red beans and rice in New Orleans*

Red beans and rice is a Cajun dish with Haitian influence and contains the “holy trinity” – bell pepper, onion, and celery. You can find this vegetable blend in the base of almost every Cajun meal, including etouffee, jambalaya, and gumbo. Red beans and rice are traditionally made with a stovetop pot set on a low boil all day. However, the ease of a slow cooker is made with the PhD student in mind as it also keeps well during the week. The most important piece is to get red beans and soak them for about 12 hours before cooking them. This will make the beans more digestible as well as more hearty. Andouille is a Cajun spiced sausage that might be at a speciality butcher shop. Another crucial ingredient, Slap Ya Mama (yes, you read that right), is only available in the U.S. Slap Ya Mama seasoning has its name because “every time a mama uses it, she receives a loving slap on the back and a kiss on the cheek for another great dish”. There are so many great memories I have from my time in New Orleans and I’m happy to share my favorite meal. I hope you are able to replicate this dish and taste the Southern Comfort that is very true for New Orleans.

Laissez les bons temps rouler!

Recipe:

Serves 6, Cook time is 4 –8 hours

450 grams of dried red kidney beans (New Orleans Camelia brand recommended)
450 grams Andouille sausage (or smoked), sliced ½ inch
4 tablespoons olive oil
1 yellow onion, diced
4 ribs celery, diced
1 green bell pepper, chopped
4 cloves garlic
1 bunch green onions, chopped and divided
3 cups chicken broth
3 cups water
1 tablespoon Slap Ya Mama seasoning
1 teaspoon black pepper
1 teaspoon dried thyme
1 teaspoon dried oregano
3 bay leaves
Handful of fresh parsley, chopped

For serving:

Cooked long-grain white rice
Hot sauce

Instructions:

Rinse beans and soak.
Brown sausages in oil on both sides. Set aside.
In the same pan, add garlic and onion, sauté for 2-3 minutes until transparent. Then add the bell pepper, celery, and half of the green onions. Sauté for 5 minutes.
To the slow cooker, add your cooked vegetables. Then add the red beans, black pepper, Slap Ya Mama, dried thyme, oregano, and bay leaves.
Add the water and chicken broth.
Set the slow cooker to high setting for 4 hours or low for 8 hours.
When beans are ready, take out 1 ½ cups to mash and put back in pot.
Remove the bay leaves and add the sausage back in. Cook until sausage is hot.
Serve over a bowl of hot white rice with hot sauce, green onions, and parsley for garnish.

Notes:

In New Orleans, they also add a split-faced grilled sausage to the top.
This can be adapted to an Instant Pot (Pressure Cooker) as well. Just set the pressure to high for 60 minutes with a 15-minute natural release.
If the beans seem too thick, add more water.
This is a great dish that can be stored for a week or frozen for two months.

Enjoy!!!

Hey there, this is Alysia!

Hey there, this is Alysia! I recently joined the Cancer Bioengineering team as a first-year PhD student. At the beginning of 2022, I was selected as a Fulbright-RCSI StAR Programme student. I spent the summer in anticipation of what to expect from my new home. I had never travelled outside of America before! However, moving to Dublin has been a great new adventure with tons of amazing experiences and new friendships. One of the first things I did when I got here was going to cafes all over town to get to know the area. Also, to indulge in the foodie scene of Dublin. I also did some great walking tours, joined a tag rugby team, got cosy with the pub culture, and found some unique thrifting shops. Dublin has a lot of charm and hidden gems wedged in between the cobblestone streets. As an American in Dublin, I thought I would have a really hard time adjusting. However, everyone has been so friendly and helpful! I’ve been able to catch on to some of the local dialogue and sometimes catch myself about to say, “it’ll be grand!”

One of my favourite things I’ve done since being in Dublin is exploring the surrounding area through hiking. I’m from Colorado in the U.S., so the mountains here are quite a bit different. However, I can greatly appreciate the hiking culture that everyone seems to enjoy. I’ve been able to go on hikes with colleagues and friends alike in new stunning locations. My first introduction to Irish hiking was along the Howth cliff walk. Not only was the wind strong enough to fly me back to America, but the rain was “lashing”, and the temperature was absolutely, “Baltic”. I was soaked to the bone but could not be happier about getting outside and finding a social hobby that would help me adjust to my new home.

It’s only been a few months into my four-year journey in Ireland, but I’m looking forward to so many opportunities. Being so close to the rest of Europe, I’ve already travelled to Paris, London, and Barcelona. I was even in Brussels and Luxembourg for a Fulbright Seminar visiting the EU and NATO! I plan on travelling around Europe some more, exploring the coasts of Ireland, and of course, sampling all the new cuisine! I really lucked out with a great team here in the Bioengineering Group. We have conferences here in Ireland as well as internationally, which helps me explore. I can’t believe I’m here in Dublin doing cancer research. Being selected for Fulbright is an incredible opportunity for me to fall in love with Dublin while doing a PhD program.

Home, sweet home…

Checking the calendar, it has been a month since my last post! That month was a transition time. Collecting all that accumulated, shipping self and stuff home, settling back and reinventing the life. Learning to drive on the left side, getting used to the narrow roads and ‘snow-flake’ junctions.

I never had a problem with driving on the right side in the US. Though, my entire driving experience as a driver has happened in Ireland driving on the left side of the road. Apparently, something that you absorb as a toddler, youngster, teenager and young adult never leaves you. It is written in your ‘hard-drive and operation system’ as a default option. So, now I have always to pay attention particularly when roads are empty…

What is my other big discovery? I was adopted by the big-big family and happily accepted this fact! I met 3 sisters and 3 brothers-in-law and a grandpa. Now, I miss our Sunday dinners and chit-chats…

2018 Raleigh Fulbright Enrichment Seminar

The theme of the seminar was American Security: Integrating Multiple Perspectives. With the great support from North Carolina University, we stepped out our comfort zones and explored security topics through lenses of our cultural backgrounds and life experiences. Food Security, Energy Security and Environmental Security. Eighty-four Fulbrighters from almost 40 countries were sharing their stories on how these issues are dealt with in their home countries! We learnt to talk through being open-minded, find things in common and come to a balanced solution. This is not a-one-size-fits-all solution. We have more in common than we have thought. We have become friends and partners who build bridges and connect people and countries. The Fulbright Programme helped us to realise it!

A part of the activities was a site visit. I picked the Food Bank for the very simple reason – I have never heard about such a concept. My imagination fueled by perceptions drew a warehouse full of canned and dried food for a ‘rainy day’. How big was my surprise when I saw an absolutely different picture! Many dedicated people with the huge help of volunteers collect, sort, pack and distribute all type of food from vegetables to meat for people who can’t afford to buy it themselves. They collect fresh vegetables that do not meet perfection standards (called also number 2) from farmers. Giant sweet potatoes, ‘ugly’ squash or oranges – they all have the same nutrition value as their glamour looking brothers and sisters. Why #2 should be left in the field? So the Food Bank takes them in. The Bank also educates people on how to cook healthy meals from raw products.

Happy Thanksgiving 2018!

On November 22, almost all Americans and visitors celebrated Thanksgiving. Roads and airports were overcrowded a day before. Turkeys, potatoes, corn and pumpkin tarts were consumed in astronomical amounts. The New York Times cherry picked 50 recipes from the 50 states. Yamee!!!! Have a look – I am voting for Alaska’s one!

So, how was my experience? As a native American – together with the family! I drove through big and small towns, beautiful autumn sunflower fields and forests covering a mile after a mile. When I thought that I was nearly there GPS updated my route with instructions to drive another 5-10 miles. So after an hour, I joined the big gathering in Grandpa’s house in northern Harford County, Maryland.

Many generations sat at the family table making it noisy, warm and live. Grandpa said the prayer. Turkey was served with many tasty sides. Some food combinations were entirely new for me… Having turkey with sweet strawberry jello was unusual. Or with cinnamon-sprinkled baked apples. Both were delicious on their own right! Two recipes I pencilled down for my family – a broccoli salad and a strawberry jello though will use them differently. If the broccoli salad perfectly fits into my vision of appetisers, the jello is for the desserts collection.

After the main men were watching sports, children were surfing the Internet, and the women cleaned the dishes and put cakes, tarts and torts on the table. Chitchat spiced with jokes and old days funny stories were all day long. What else would you wish for?

Sharing this day with this American family recalled childhood memories when I was stepping into my Granny’s arms in a warm kitchen smelled with baked pies and pastries from chilly and wet outdoors.

Americans see Thanksgiving as a day of feasting, football and family. Why not? Traditions are not bad at all. In the modern busy life, family dinners link us together letting stop the moment, smile at each other and thank for being here and now. By the end of the day, the family matters more than any anything else. Isn’t it?

Sightseeing discoveries in Baltimore

Coming to live and work for a short period ignites opposite feelings. Should I see all the places recommended by Tripadvisor or do it at my pace as it happens? What if I miss something worthy? Perhaps, your own intuition balances somehow both.

I have discovered and loved two buildings in Baltimore. One is the building of Barnes & Noble bookstore in Inner Harbour and the other is Mount Vernon Place Church. Both have a great history behind and give a very warm feeling when you are inside.

Barnes & Noble bookstore is located in the former Power Plant. The features are easily spotted. From outside, the building looks like a Plant for modern social activities. Ugly slightly, isn’t it? Though, it is a different feeling when you enter the bookstore. The Plant scaffolds, chimneys and pipes are nicely crafted into a warm welcoming environment. Even lights are dimmed as back then. Rambling through the bookshelves and feeling the magic of the place and unread stories on them. You can pick up a book, sit where you are and enjoy the reading. Maybe it is the feeling of my childhood full of books and hours of reading?

Mount Vernon Place Church is next to the Washington Monument and recalls old Catholic Cathedrals in a Victorian Gothic Style. Built in 1872, the Church is actually the United Methodist Church from the very beginning. It is beautiful inside as well as outside. The stained glass and carvings have Nature themes. A big rose window in the rear of the church was inspired by the one in Notre Dame. It has an interesting history which you can read here. I discovered this place by chance and am glad that this chance came from my host family. I saw the interior not only the Church but also Asbury House. The mansion was a home to the first bishop of the Methodist Church in America – Francis Asbury (1745-1816). Have a look at the pictures, the furniture is well preserved, the staircase is similar to the one you can see in Slane Castle. Its light design makes it looks flying. Indeed, not everyone could use it at that times. Servants had a plain version at the back of the house, so none could have seen them moving in and out. Lots of blue and carved wood in the rooms. Incredibly beautiful.

Taste of Guinness in Baltimore

What is a must-see in Ireland? Right: visit Guinness brewery at St. James’s Gate and have a pint of right Guinness. It is one of the most recognised and famous beer brands. Rumours say Dublin is the only place where Guinness tastes Guinness. Traditions, traditions and traditions. Though the one we like most Guinness Draught is a relatively new addition – it was introduced almost 200 years after the brewery establishment in 1759 by Arthur Guinness.

So, what if you like tastes ‘outside the box’? Then Guinness brewery in Baltimore is for you. Respecting the Father, they do completely different stuff. Imagine, 16 different tastes, including the one we know! You can have a guided tour of the brewery, hear the great story and do a beer tasting. Have you tried one? Not, the one in the pub or with the friends at BBQ. It is a special way to feel the bouquet of flavours and taste the difference. There is a difference between the beer drunk straight from the bottle and from the glass. Because you can smell it as simple as that.

Taste of Guinness, the Guinness Brewery opened in Baltimore, MD, the USA in 2017

During our guided tour, we rambled inside the experimental brewery, learn the basics of beer production, tasted 4 types of beer: Guinness Blonde, Oatmeal Pale Ale, Guinness Draught and Guinness Milk Stout. Three were absolutely new for me. I liked Oatmeal Pale Ale, found Milk Stout a bit dessert style, Blonde – too citrusy. Do not forget, another 12 you can taste at the bar in a special set! However, to enjoy the most you have to bring your friends. All is much better with the right company!

Halfway through

Can you control the time? I can’t and know none who can. It flies, when things around you work out, and drags on when not. The time flies for me here in Baltimore. It feels so intense sometimes and then slightly slows down. I take pictures almost of everything: the path’s signposts when rambling in the network of Johns Hopkins Buildings, the first frosty morning, joyful deer at the backyard of my host family house, outdated clothes in the shop…

In the past, I had a similar journey to Ireland. It was 3 months research placement during my PhD. Did I like it – oh, yes I did! I travelled a lot, felt romantic and changed my life on my return home. But I did not run a diary or tag my way on Facebook. I have learnt the lesson: do it even more intense as you can’t travel back in time and write down your experience. It may be funny or educational to read in a couple of years! I become addicted to it though not always have time to do it.

I like the people who I am working with. They are a fantastic bunch of self-motivators and open-minded personalities. They are workaholics either naturally like me or because of the exciting projects they do like I do. Who knows, but very likely because of both. Isn’t it a dream to have an exciting project and great people around you? The luck like this gives you wings.

The American enthusiast studying Russian and my Mum

The host family – is my other great luck! This luck was crafted as a parallel story when none knew how the Fulbright application and an American enthusiast learning Russian may intersect. You would not believe, but parallel lines can be non-parallel sometimes! His journey to my home city in Russia paved the way to the opportunity to stay at his aunt’s house.

Every day 50 min drive to and from Hopkins opens up the other side of the local lifestyle and infrastructure. What are the rush hours? How many drivers are signalling before taking a turn? How do they call the shopping trolley? How parking system works?
