In 2013, he became a scientific cofounder of Editas Medicine, a company developing CRISPR therapies for genetic diseases. Now, they’re up to Phase II data, which execs earlier maintained could pave the way to a quick OK, and the team is giving little away. And execs want an EUA now, GSK, Vir cleared to leap into PhIII, angling for a spot in the Covid-19 antibody race led by Lilly, Regeneron, Amgen posts upbeat assessment of PhII KRAS data on AMG510 — but there's no clear picture of what researchers saw, Medicxi splashes more funding into Janpix's STAT protein degrader program, Jim Allison and Pam Sharma back a Canadian AI upstart seeking to solve the tumor stroma puzzle, Jumping ahead of Merck and others, Bristol Myers declares a PD-1 first in NSCLC, UPDATED: Bristol Myers offers a big premium to reel in MyoKardia's cardio pipeline with a $13B buyout. What this does is open up a lot of different types of mutations that weren’t available previously.
Liu quickly became a pioneer of DNA-templated synthesis, now commonly called DNA-encoded libraries, a method of appending small molecules to DNA strands to generate many combinations of new molecules. COVID-19 has demanded unprecedented speed and innovation in drug development, and the time is right to re-think what’s possible. Liu’s current office at the Broad Institute of MIT & Harvard is tamer. And he’s working with a former graduate student on starting a sixth. “It was an amazing experience.” He still keeps a case full of poker chips from their travels.
We'll e-mail you a link to set a new password. At the time, scientists were already fashioning such proteins with directed evolution, a laborious technique that involved mutating large batches of genes, weeding out the protein progeny of interest, then repeating the cycle to arrive at a protein with the desired properties. The goal is to combine a chemist’s ingenuity with the Darwinian brutality of natural selection to access molecules that are more perfect than what man or nature alone could create. Since base editors debuted in 2016, Liu receives one or two letters from parents like Gladstone every day. Corey’s lab “filled me with this amazing reverence for and belief in the power of synthetic chemistry,” Liu says. “We just anticipated that if it did succeed it would be really useful to the field, and potentially to patients.”. But Amgen is taking it to a whole new level with its Phase II snapshot on the KRAS G12c drug sotorasib — aka AMG 510. Doug Cole, a managing partner at the venture capital firm Flagship Pioneering, remembers meeting Liu, then a new professor.
Cas9, the enzyme used in CRISPR gene editing, lines up with a specified sequence of DNA and cuts it, like a pair of molecular scissors. He is reluctant to see himself in those terms, but everyone around him seems to recognize the potential lurking inside that insatiably thirsty mind. Please note the magic link is one-time use only and expires after 24 hours.
In the past few years, Liu’s lab has evolved from an incubator of promising science into a hub of transformative discoveries. Your account has been created successfully, and a confirmation email is on the way. That’s probably overselling where the tech is today – Dow said they only tested it on four human cell types, leaving questions on how it will fare in the rest – but it gets at the potential. “I turned to my daughter and said, ‘They are talking about you,’ ” Gladstone says. They also were able to edit in non-dividing such as neurons and liver cells. That broke Liu’s long-standing rule: “If step one is evolve your starting material, then don’t pick that project.” Even if they could evolve the enzyme, there was no guarantee they could coax it into editing DNA in cells. Renew your membership, and continue to enjoy these benefits. In the past six months alone, Liu’s group has landed four publications related to CRISPR in the pages of Science and Nature. In 1990, he won the California Junior Science & Humanities Symposium. “But the fact that David has had that happen several times to him, throughout his career, may indicate that it’s not just luck.”. And now those upstarts are being followed by a whole new wave of companies that are applying improvements on the duo’s foundational work. To pivot the tech into therapeutic applications, Liu also launched Prime Medicine with the backing of Arch Venture Partners, GV, Newpath Partners and F-Prime.
Liu’s legacy is already apparent in his students’ successes. On Wednesday, Cambridge, MA-based Janpix announced the closing of a modest $10 million Series B led by Medicxi. Komor recently became an assistant professor at UCSD. Esvelt couldn’t get the idea to work in practice, though, and Liu began wondering how many years a responsible adviser should allow a student to continue with no successful results. With his own lab, Liu began exploring evolution on the molecular scale. “My parents never pushed me to be a scientist,” Liu says, but his curiosity pulled him there anyway.
Soon after, he began informally teaching a group of card-counting Harvard undergraduates. Addgene is a nonprofit plasmid repository dedicated to improving life science research. Die Forscher testeten ihr neues System in menschlichen Zellen an mehr als 175 bekannten Mutationen, die teils schwerste Krankheiten verursachen.
Known as CRISPR, such tools
The problem was Liu’s first discovery –and Beam Therapeutics, the company he launched around it – had major difficulty attacking sickle cell, because that first gadget could only make four switches: C-to-T, T-to-C, A-to-G, and G-to-A.

He has founded five companies, each based on a potentially transformative technology, a breadth of innovation that is typically reserved for engineers. Sign in with a different account. That difference may seem trivial, but it meant that Gaudelli would have to think bigger if she wanted to develop the first adenine base editor. Join us to get the news you need.
In yesterday’s Nature paper, Liu and his coauthors switched T to A. “The evidence in this case for correcting those disease alleles is the first step and that’s a long way off from the last step.”. His first big discovery as an independent scientist came out of a desire to appropriate the genetic code of DNA to allow scientists to create hundreds or thousands of new molecules that could be screened for drug activity. Liu is on track to become an important name in the biotech industry—a serial entrepreneur along the lines of a Robert Langer or Greg Verdine. David Liu unveils newest advancement in CRISPR tech: Prime editing. The breakthrough swiftly inspired hundreds of academic studies and spawned a wave of biotech startups like Intellia, CRISPR Therapeutics and others that sought to apply the tech to the development of new therapies.
