Now some are embracing a brand new paradigm: Measure all the things, ask questions later. This motto drives a lab at Harvard and MIT’s Broad Institute, the place researchers have developed a way for producing a treasure trove of data on a cell’s internal workings that they will sift for years to return. The methodology, often known as Cell Painting, impressed scientists at a number of pharmaceutical firms—a lot that they launched a consortium and pooled assets, utilizing the method to create a large information set that they started releasing to the general public in November. The JUMP–Cell Painting Consortium, because it’s called, hopes the database will speed up drug discovery by serving to researchers establish promising compounds and get a greater sense of what they do and what kinds of unwanted side effects they could have earlier than the molecules get examined in animals or individuals.
Cell Painting makes use of as much as six fluorescent dyes to gentle up main elements of the cell, such because the nucleus and mitochondria. A microscope snaps photographs of the varied stains, and software program measures morphological options like dimension, form, depth, and texture, creating an image-based profile of the pattern. It is “just about the simplest imaging assay you can manage,” says computational biologist Anne Carpenter, who developed the tactic and co-leads the Broad Institute lab with Shantanu Singh. “Our mission was to choose the absolute cheapest, easiest dyes.”
Beyond ease of use, the ability of Cell Painting lies within the sheer quantity of information that comes from one experiment. The newly launched database accommodates photographs of cells responding to greater than 140,000 perturbations—both a drug therapy or another modification that turns a gene’s exercise up or down. Using this information set, Carpenter and a few of her colleagues discovered a dozen compounds that appear to have an effect on the identical constructions which can be influenced by a key gene concerned in a fast-growing muscle most cancers. Rather than placing a whole bunch of samples by way of a number of rounds of wet-lab experiments, the Broad researchers got here up with the drug listing a number of years in the past by typing the title of the gene into the database.
“It’s a totally different approach that has a lot fewer steps and is a lot less costly,” says T.S. Karin Eisinger, a biologist on the University of Pennsylvania who research that specific muscle most cancers. Her crew labored with Carpenter’s to validate the compounds in wet-lab assessments, and the 2 scientists are launching an organization to additional develop essentially the most promising candidates. Others are a bit additional alongside: Recursion Pharmaceuticals, an organization in Salt Lake City for which Carpenter is an advisor, has already launched 5 medical trials to check drug candidates recognized utilizing a model of Cell Painting.
As it wraps up its public launch, consortium members are gearing as much as work with the Health and Environmental Sciences Institute, primarily based in Washington, DC, to see if they will pair outcomes from Cell Painting with different information to foretell the toxicity of prescription drugs and agrochemicals.
