Thinking, working, racing and sweating -- Velosano 5: 100% for the cure.

I owe a lot of updates from the lab, but first let me advertise a bit for a charity bike ride I'm doing in next month.

Like last year, I am riding in the Velosano cancer charity bike ride. I will be riding 200 miles over two days in support of important, innovative research done here in Cleveland under the auspices of the Cleveland Clinic and the Case Comprehensive Cancer Center.  Last year was my first year riding, and thanks to you, I raised over $4,000 (over $4 MILLION was raised overall). I started alone (this is a LONG ride to do alone), but eventually was adopted by a 'wolf pack' of riders who I had never met. This group of riders became like a little family over the next two days, and included founding members of the ride.

What I didn't know at the time was the my lab would end up being directly supported, to the tune of $100,000 by this ride. This is particularly important, as we are a young lab, and do thing quite differently than many, and this seed grant has allowed us to think completely outside the box -- and to pursue a project that would have little chance at standard funding methods.  I'd like to tell you a little about it.

First off, I think it's important to realize that I see cancer research almost entirely differently than most do.  I am not interested in new drug development (this takes decades, and BILLIONS of dollars) because we already have excellent drugs... we just don't know how to use them in the face of a changing, evolving foe.  Cancer, like all living entities, responds dynamically to external stresses... by EVOLVING. Therefore, the focus of our lab (which you can find out more about here) is the purposeful, direct study of the evolutionary process.  We are not interested in any one of the uncountable ways cancer evolves resistance to drugs (mutations) but instead on the process by which these solutions are chosen. We study this in a number of ways, typically with mathematics.

Recently, however, we have begun to start thinking about how to design experimental systems that give us the ability to constantly monitor the genomic changes in evolving populations of cancer cells -- the idea being if we can monitor these changes in real time (not just after months of treatment), we can learn the patterns in more detail. We are seeking to know our enemy's ways, not just stop any individual plan. To do this, we have had to rethink how experimental systems work, and to design one of our own, which we call EVE (the EVolutionary biorEactor). EVE will be a robotic system consisting of state of the art sensors, computer programs we had to write ourselves, microcontrollers, pumps, and an interface between the biology itself, and this robotic system. This requires many scientists, from many disciplines to come together -- making funding from tradition, focused, funding boards almost impossible. We are basing this system on a 'morbidostat' that was published previously, and also are using some open source parts from the eVOLVER project - but the application to cancer is brand new, and making the jump from bugs/yeast to cancer carries a lot of difficult bits.

With flexible funding like that raised in this event, however, the funding board can take a risk... and while I'm not suggesting that this device will sort out all our problems, history tells us that breakthroughs come from the fiery interface between disciplines, which is where my lab sits.  There are some cool schematics and diagrams you can see describing this project (and others) in our lab on our research in progress page here.

We have also just recently gotten the baseline device working, and can now proudly show off a gorgeous logistic growth curve ...  next steps are to start killing the bugs.  

holy moly - it's logistic growth!!!  (optical density vs. time E. coli growth in media, no antibiotics, well done Nikhil and team)

While we're still behind the groups that pioneered these systems, we are learning fast, and will soon start evolving cancer cells, and testing drug combinations in earnest to see if we can steer evolution, optimize the timing of therapy, and test how repeatable evolution really is, and how this maps to secondary drug sensitivities.

If you gave to my ride last year, THANK YOU, and please consider continuing your support of this important process.  If you are a first time donor, THANK YOU for considering, and know that every dollar counts.

These grants help support the equipment and salaries of the hard working folks who make this research happen. Many folks in the lab have touched this project, but Nikhil, Julia and Erin have been the driving forces of late - and so we went to a Velosano launch party last night to show off the research. Nikhil even brought along some props to show off to interested passers-by, in this case Kara - part of my wolf pack!




tl;dr: I'm hoping to get to $5,000 for my ride this year - please consider helping me.  If you can't donate, please consider sharing this post, or the donation link (below), with your social network to help expand the reach.  The fight against cancer is one we are all touched by. 

If you are in the Cleveland area, you could also consider joining our team, or volunteering - every rider, every dollar and every volunteer help the cause.

To donate to my ride, and to support cutting edge research like this, please follow this link, and press the green DONATE button.

  1. I was depressed when doctor told me that I have been diagnosed with Herpes disease… I thought about my Family, I know my Family will face a serious problem when I'm gone, I lost hope and I wept all day, but one day I was searching the internet I found Dr.ezomo contact number. +2349069171173 I called him and he guided me. I asked him for solutions and he started the remedies for my health. Thank God, now everything is fine, I'm cured by Dr.ezomo herbal medicine, I'm very thankful to Dr.ezomo and very happy with my hubby and family. email him on dr.ezomorootandherbals@gmail.com or you can also reach him through WhatsApp number+2349069171173
    He can also cure so many sickness

  2. I have been suffering from (HERPES) disease for the last four years and had constant pain, especially in my knees. During the first year, I had faith in God that I would be healed someday.This disease started to circulate all over my body and I have been taking treatment from my doctor, a few weeks ago I came on search on the internet if I could get any information concerning the prevention of this disease, on my search I saw a testimony of someone who has been healed from (Hepatitis B and Cancer) by this Man DR ikhuele and she also gave the email address of this man and advise we should contact him for any sickness that he would be of help, so I wrote to DR ikhuele telling him about my (HERPES Virus) he told me not to worry that I was going to be cured!! hmm i never believed it,, well after all the procedures and remedy given to me by this man few weeks later I started experiencing changes all over me as the DR assured me that I have cured, after some time i went to my doctor to confirmedave been finally healed behold it was TRUE, So friends my advice is if you have such sickness or any other at all you can email DR ikhuele on( dr.ikhuelespellhome@outlook.com sir I am indeed grateful for the help I will forever recommend you to my friends!!! with your lovely Email Address ( dr.ikhuelespellhome@outlook.com or you can also WhatsApp him on this number +2348064752987
