Symptoms
of pancreatic cancer are not very specific to the disease. They include
fatigue, weight loss, nausea and loss of appetite, all symptoms of any number
of ailments as well as most types of cancer. Small tumors on the pancreas are also
difficult to detect with CT or PET scans due to its location between the
stomach and spine.
After
three months of research, Jack came across a study identifying mesothelin as a
biomarker for pancreatic cancer. Mesothelin (MSLN) is a protein present on
normal mesothelial cells which line the internal organs and are present
throughout the entire body.
Pancreatic
cancer and mesothelioma have a few things in common, both tend to be diagnosed
late stage, both are difficult to treat due to that fact and as a result, both
come with a very poor prognosis. Both are also forms of cancer with an over
expression of the protein MSLN.
It was
when Jack was learning about carbon nanotubes (CNTs) in Biology class that he
had his ah-ha! Moment though. CNTs are extremely
small particles and because of their unique electrical and chemical properties,
they present very exciting opportunities for scientific research. Jack thought that he
could lace antibodies to CNTs so that they would react to MSLN.
Jack sent
his proposal to 199 professors before receiving approval from Johns Hopkins
professor, Dr. Anirban Maitra. Dr. Maitra gave Jack use of his lab to develop a
filter paper test strip dipped in CNT’s which when exposed to a blood sample,
the MSLN in the blood binds with the antibodies to form larger molecules thus
changing the paper strip’s electrical properties.
The
test is potentially 100% accurate, costs about three cents, takes about five
minutes and is over 100 times more sensitive than current tests. It has already
been tested and proven accurate in blind human trials.
Earlier
diagnosis of mesothelioma holds the potential to turn the fatal disease into a
chronic one. Pacific Meso Center is currently working to develop a breath test
that will be able to detect a person’s pre-disposition to mesothelioma from the
microscopic molecules carried in a their breath.
Jack
received the Gordan E. Moore award at the Intel International Science and
Engineering Fair for his invention, earning a $75,000 prize and has been
contacted by multiple companies about potentially licensing or commercializing
his idea.
