(DUBAI) -
Mayo Clinic researchers
have pioneered an artificial
intelligence (AI) tool,
called OmicsFootPrint, that
helps convert vast amounts
of complex biological data
into two-dimensional
circular images. The details
of the tool are published in
a
study in Nucleic Acids
Research.
Omics is
the study of genes, proteins
and other molecular data to
help uncover how the body
functions and how diseases
develop. By mapping this
data, the OmicsFootPrint may
provide clinicians and
researchers with a new way
to visualize patterns in
diseases, such as cancer and
neurological disorders, that
can help guide personalized
therapies. It may also
provide an intuitive way to
explore disease mechanisms
and interactions.
"Data becomes most powerful
when you can see the story
it's telling," says lead
author
Krishna Rani Kalari, Ph.D.,
associate professor of
biomedical informatics at
Mayo Clinic's Center for
Individualized Medicine.
"The OmicsFootPrint could
open doors to discoveries we
haven't been able to achieve
before."
Genes act
as the body’s instruction
manual, while proteins carry
out those instructions to
keep cells functioning.
Sometimes, changes in these
instructions — called
mutations — can disrupt this
process and lead to disease.
The OmicsFootPrint helps
make sense of these
complexities by turning data
— such as gene activity,
mutations and protein levels
— into colorful, circular
maps that offer a clearer
picture of what’s happening
in the body.
In
their study, the researchers
used the OmicsFootPrint to
analyze drug response and
cancer multi-omics data. The
tool distinguished between
two types of breast cancer —
lobular and ductal
carcinomas — with an average
accuracy of 87%. When
applied to lung cancer, it
demonstrated over 95%
accuracy in identifying two
types: adenocarcinoma and
squamous cell carcinoma.
The study showed that
combining several types of
molecular data produces more
accurate results than using
just one type of data.
The OmicsFootPrint also
shows potential in providing
meaningful results even with
limited datasets. It uses
advanced AI methods that
learn from existing data and
apply that knowledge to new
scenarios — a process known
as transfer learning. In one
example, it helped
researchers achieve over 95%
accuracy in identifying lung
cancer subtypes using less
than 20% of the typical data
volume.
"This
approach could be beneficial
for research even with small
sample size or clinical
studies," Dr. Kalari says.
To enhance its
accuracy and insights, the
OmicsFootPrint framework
also uses an advanced method
called SHAP (SHapley
Additive exPlanations). SHAP
highlights the most
important markers, genes or
proteins that influence the
results to help researchers
understand the factors
driving disease patterns.
Beyond research, the
OmicsFootPrint is designed
for clinical use. It
compresses large biological
datasets into compact images
that require just 2% of the
original storage space. This
could make the images easy
to integrate into electronic
medical records to guide
patient care in the future.
The research team
plans to expand the
OmicsFootPrint to study
other diseases, including
neurological diseases and
other complex disorders.
They are also working on
updates to make the tool
even more accurate and
flexible, including the
ability to find new disease
markers and drug targets.

and funding.
