(Press-News.org) Now-live SOAR platform is a one-stop shop to help scientists explore how genes behave differently in various parts of the body, show them how cells might be talking to each other
SOAR aggregates 3,461 tissue samples from 13 species and 42 tissue types to help scientists zero in on the exact biological processes that could be targeted to treat diseases
Big Pharma is looking to use the tool in their research
CHICAGO --- Scientists at Northwestern University have developed the largest open-access resource of its kind to help researchers shave off months of early-stage drug development time by allowing them to better understand diseases and find potential treatments.
Called SOAR (Spatial transcriptOmics Analysis Resource), the now-live platform is a one-stop shop that helps scientists explore how genes behave differently in various parts of the body, shows them how cells might be talking to each other and enables them to find new drug possibilities.
Spatial transcriptomics is a cutting-edge scientific method that helps researchers see which genes are active in different parts of a tissue, essentially giving scientists a bird’s eye view of cell interactions. SOAR is the first comprehensive spatial-transcriptomics resource designed expressly to accelerate drug-discovery pipelines.
“It’s too expensive and too time consuming to push thousands of potential drug candidates to the preclinical study and clinical trials,” said corresponding author Yuan Luo, chief AI officer of the Northwestern University Clinical and Translational Sciences (NUCATS) Institute and the Institute for Artificial Intelligence in Medicine at Northwestern University Feinberg School of Medicine. “We need to pick the right leads and then push them to downstream studies. This resource will help prioritize that.”
Research findings using the resource will be published June 11 in Science Advances. Several pharmaceutical companies are already looking to use SOAR in their research, Luo said.
Gives researchers a ‘molecular GPS’
SOAR aggregates data across 441 spatial transcriptomics datasets from 19 different spatial transcriptomics companies, allowingresearchers to see detailed maps of gene activity across 3,461 tissue samples from 13 species (from humans to zebrafish) and 42 tissue types (e.g. breast, lung, brain, bowel, etc.).
By showing how genes are expressed — turned on or off — in different parts of a tissue and connecting that to how certain chemicals affect cells, this dataset acts like a “molecular GPS” — helping scientists zero in on the exact biological processes that could be targeted to treat diseases, Luo said.
Studying IBS to breast cancer
With disease, Luo said it’s often not the cell activity itself that is problematic, but rather where the cell activity is occurring.
“If immune cells are attacking normal cells in regular tissue, that’s really bad because that could give you inflammatory disease, like the irritable bowel disease,” Luo said. “Or if the immune cells are not attacking cancer cells in a tumor microenvironment, that is really a bad thing because it lets the cancer grow.
“SOAR helps examine the variability and interactions to give researchers the understanding of what mechanism is going on so they can better understand what is underlining the disease.”
Peking University’s Zexian Zeng (a former trainee in the Luo lab and Northwestern alumnus) is a co-corresponding study author. Other Northwestern authors on the study include Yiming Li, Yanyi Ding, Saya Dennis, Meghan R. Hutch, Jiaqi Zhou, Yawei Li, Maalavika Pillai, Sanaz Ghotbaldini, Mario Alberto Garcia, Mia S. Broad, Chengsheng Mao and Parambir S. Dulai.

CAMBRIDGE, MA -- As more connected devices demand an increasing amount of bandwidth for tasks like teleworking and cloud computing, it will become extremely challenging to manage the finite amount of wireless spectrum available for all users to share.
Engineers are employing artificial intelligence to dynamically manage the available wireless spectrum, with an eye toward reducing latency and boosting performance. But most AI methods for classifying and processing wireless signals are power-hungry and can’t operate in real-time.
Now, MIT researchers have developed a novel AI hardware accelerator that is specifically designed for wireless signal processing. Their optical processor ...
Why do people develop antibodies to food? While clinicians have long observed that healthy humans develop a particular type of antibody, called IgG, to the foods they eat, the reasons for this phenomenon have remained unknown. Researchers, led by investigators from Allergy and Immunology at Mass General Brigham, have identified the mechanism underlying IgG antibody development to food proteins. They discovered that humans are intrinsically predisposed to develop a particular type of IgG antibody to peanut by human antibody genes. These antibodies develop, whether or not they develop peanut allergy. Results are published in Science Translational ...
A new large-scale study has mapped the first molecular events that drive the formation of harmful amyloid protein aggregates found in Alzheimer’s disease, pointing towards a new potential therapeutic target.
Published today (11 June) in Science Advances, researchers from the Wellcome Sanger Institute, Centre of Genomic Regulation (CRG) and Institute for Bioengineering of Catalonia1 (IBEC) used large-scale genomics and machine learning to study over 140,000 versions of a peptide called Aβ42, which forms harmful plaques in the brain and is known to play a central role in Alzheimer’s disease.
This research is a significant step towards helping scientists find new ...

In a new study, physicists at the University of Colorado Boulder have used a cloud of atoms chilled down to incredibly cold temperatures to simultaneously measure acceleration in three dimensions—a feat that many scientists didn’t think was possible.
The device, a new type of atom “interferometer,” could one day help people navigate submarines, spacecraft, cars and other vehicles more precisely.
“Traditional atom interferometers can only measure acceleration in a single ...
Under what conditions would it be right — or is it never acceptable — to eliminate a harmful species from our planet? That’s what an international team of researchers, including Professor of Philosophy Dr. Clare Palmer from Texas A&M University, explores in a study published in Science.
In the study, “Deliberate extinction by genome modification: An ethical challenge,” researchers examine the controversial idea of using genetic engineering for local and full species extinction as a conservation strategy. They conducted ...
Two recent studies suggest there is no significant benefit of early biologics over standard step-up care with methotrexate2,3, but these did not select for poor prognosis. The aim therefore of the SPEED trial (Severe Psoriatic arthritis – Early intervEntion to control Disease) – which was funded by the National Institute for Health Research (NIHR) – was to compare disease activity in 192 PsA patients with poor prognostic factors when treated with one of three regimens: standard step-up with conventional systemic disease-modifying ...

LONDON, ON – A groundbreaking clinical trial led by London Health Sciences Centre Research Institute (LHSCRI) and Western University’s Schulich School of Medicine & Dentistry may enhance how medical professionals detect hidden blood clots responsible for strokes. The study, published in The Lancet Neurology, is the first to show that extending imaging to include the heart within minutes of a patient’s arrival to hospital with an acute stroke significantly improves the ability to determine the stroke’s underlying cause. This innovative diagnostic approach can be used to determine an effective and tailored treatment plan for preventing future strokes.

Ateneo de Manila University researchers warn that young Filipinos graduating with a degree in nursing or medicine face an uphill battle for stable employment, fair pay, and meaningful roles in the local public health system.
This comes as the Philippines faces a massive shortage of health professionals, with less than eight doctors per 10,000 people—below the international standard of 10 per 10,000—and over 127,000 vacancies for nurses, particularly in rural areas and private facilities.
The researchers found that many new graduates feel lost and unsupported ...
