A technique called Cell Painting could speed drug discovery

1 year ago 101

Now immoderate are embracing a caller paradigm: Measure everything, inquire questions later. This motto drives a laboratory astatine Harvard and MIT’s Broad Institute, wherever researchers person developed a method for generating a treasure trove of accusation connected a cell’s interior workings that they tin sift for years to come. The method, known arsenic Cell Painting, impressed scientists astatine respective pharmaceutical companies—so overmuch that they launched a consortium and pooled resources, utilizing the attack to make a monolithic information acceptable that they began releasing to the nationalist successful November. The JUMP–Cell Painting Consortium, arsenic it’s called, hopes the database volition accelerate cause find by helping researchers place promising compounds and get a amended consciousness of what they bash and what sorts of broadside effects they mightiness person earlier the molecules get tested successful animals oregon people.

Cell Painting uses up to six fluorescent dyes to airy up large components of the cell, specified arsenic the nucleus and mitochondria. A microscope snaps images of the assorted stains, and bundle measures morphological features similar size, shape, intensity, and texture, creating an image-based illustration of the sample. It is “just astir the simplest imaging assay you tin manage,” says computational biologist Anne Carpenter, who developed the method and co-leads the Broad Institute laboratory with Shantanu Singh. “Our ngo was to take the implicit cheapest, easiest dyes.” 

Beyond easiness of use, the powerfulness of Cell Painting lies successful the sheer measurement of information that comes from 1 experiment. The recently released database contains images of cells responding to much than 140,000 perturbations—either a cause attraction oregon immoderate different modification that turns a gene’s enactment up oregon down. Using this information set, Carpenter and immoderate of her colleagues recovered a twelve compounds that look to impact the aforesaid structures that are influenced by a cardinal cistron progressive successful a fast-growing musculus cancer. Rather than putting hundreds of samples done aggregate rounds of wet-lab experiments, the Broad researchers came up with the cause database respective years agone by typing the sanction of the cistron into the database. 

“It’s a wholly antithetic attack that has a batch less steps and is simply a batch little costly,” says T.S. Karin Eisinger, a biologist astatine the University of Pennsylvania who studies that peculiar musculus cancer. Her squad worked with Carpenter’s to validate the compounds successful wet-lab tests, and the 2 scientists are launching a institution to further make the astir promising candidates. Others are a spot further along: Recursion Pharmaceuticals, a institution successful Salt Lake City for which Carpenter is an advisor, has already launched 5 objective trials to trial cause candidates identified utilizing a mentation of Cell Painting.

As it wraps up its nationalist release, consortium members are gearing up to enactment with the Health and Environmental Sciences Institute, based successful Washington, DC, to spot if they tin brace results from Cell Painting with different information to foretell the toxicity of pharmaceuticals and agrochemicals.
