Regeneration mechanism could provide target for liver disease drugs

Drug Target Review | November 06, 2019

A newly-discovered molecular mechanism that allows damaged adult liver cells to regenerate could pave the way for drugs for chronic liver diseases. A molecular mechanism that allows damaged adult liver cells to regenerate has been discovered and could pave the way for drugs to treat conditions such as cirrhosis or other chronic liver diseases where regeneration is impaired. The researchers used mice and liver organoids (‘mini-livers’ generated in the lab from mouse liver cells) to study adult liver regeneration. They discovered that a molecule called TET1 is produced in healthy adult liver cells during the first steps of regeneration, and that this process is mimicked in liver organoids, where it has a role in stimulating organoid growth. “We now understand how adult liver cells respond to the changes caused by tissue injury,” said Dr Luigi Aloia, first author of the paper and postdoctoral researcher at the Gurdon Institute “This paves the way for exciting future work to boost cell regeneration in chronic liver disease, or in other organs where regeneration is minimal such as the brain or pancreas.”

Peptilogics and Cerebras Systems Partner on AI Solutions to Advance the Future of Peptide Therapeutics

Cerebras Systems , Peptilogics | August 19, 2021

Cerebras Systems, the pioneer in high performance artificial intelligence (AI) compute, and Peptilogics, a biotechnology platform company and an emerging leader in leveraging computation to design novel therapeutics, today announced a collaboration to accelerate the development cycle of peptide therapeutics through AI. Leveraging the revolutionary Cerebras CS-2 system – powered by the world’s fastest AI processor – Peptilogics will be able to push the boundaries of innovation in drug design and novel peptide therapeutics. This cutting-edge exploration of innovation is a scientific game changer with the potential to meaningfully reduce the time from bench to bedside. “Our mission at Peptilogics is to radically alter drug development and realize the full potential of peptides as therapeutics,” said Nick Nystrom, PhD, SVP and Head of Computation and Data, Peptilogics. “By partnering with Cerebras, we will be able to accelerate our research by orders of magnitude for important areas such as membrane proteins, including G protein coupled receptors (GPCRs). Traditional drug discovery operates on the time scale of one new drug in ten years. We aim to flip that to ten new leads in one year.” Peptides are sequences of amino acids, essentially small proteins, that play critical roles in how our bodies operate. They offer relatively unexplored opportunities for therapeutics, conferring potential advantages over other types of drugs. The “design space,” or number of possible peptide structures, is vastly larger than could be explored through traditional drug discovery. AI – specifically deep learning – is well-suited to identify ideal peptide structures as drug candidates. Through this collaboration, Cerebras and Peptilogics scientists will use the CS-2 system to develop and run advanced models to identify novel peptide therapeutics that meet specific biological activity and biophysical criteria. By accelerating the slowest step of the research cycle and training deep learning models on big data, Peptilogics with Cerebras will be positioned to deliver better therapeutics sooner. Peptilogics joins other life science leaders, including GSK and AstraZeneca, in leveraging Cerebras’ industry-leading AI technology to advance drug discovery. “Peptilogics is operating at the forefront of AI-enabled drug design. With Cerebras, they are part of a select group of partners that share similar interests in pushing the boundaries of scientific research and AI computing to radically accelerate innovation for better healthcare outcomes,” said Andy Hock, VP of Product at Cerebras. “Cerebras Systems makes world-leading AI compute accessible and easy to use so that our partners at Peptilogics can test more ideas quickly, reduce the cost of curiosity, and achieve their mission of discovering peptide therapeutics in record time.” About Cerebras Systems Cerebras Systems is a team of pioneering computer architects, computer scientists, deep learning researchers, and engineers of all types. We have come together to build a new class of computer to accelerate artificial intelligence work by three orders of magnitude beyond the current state of the art. The CS-2 is the fastest AI computer in existence. It contains a collection of industry firsts, including the Cerebras Wafer Scale Engine (WSE-2). The WSE-2 is the largest chip ever built. It contains 2.6 trillion transistors and covers more than 46,225 square millimeters of silicon.

Mission Bio and S2 Genomics to Provide Tumor Sample for Single-cell DNA Analysis

Mission Bio | April 20, 2022

Mission Bio, Inc., a leader in high-throughput single-cell DNA and multi-omics analysis, announced today a co-marketing agreement with S2 Genomics, Inc., a leading developer of laboratory automation solutions for processing solid tissues for single-cell applications, to provide a single streamlined workflow for solid tumor applications from sample prep to analysis. Christine A. Iacobuzio-Donahue, MD, Ph.D., Director of the Center for Pancreatic Cancer Research at Memorial Sloan Kettering Cancer Center (MSKCC), validated the automated nuclei workflow, which she presented at the American Association for Cancer Research (AACR) Annual Meeting last week. Single-cell DNA analysis has revolutionized cancer research, allowing researchers to gain high-resolution insights into tumor heterogeneity, leading to a slew of high-profile papers on disease causes. Solid tumor profiling, on the other hand, presents significant problems, as existing prep procedures sometimes fail to yield enough cells or nuclei to offer relevant data. Mission Bio introduced their Tapestri Solution for Solid Tumor Research last month to address this issue, which includes new pre-designed research panels for breast cancer and glioblastoma multiforme, as well as an upgraded single-cell copy number variation (CNV) bioinformatic analysis tool. S2 Genomics' SingulatorTM 100 technology for automated dissociation of solid tissue into single-cell or nuclei suspensions can now be used in conjunction with Tapestri to achieve scalable, high-yield, efficient, and repeatable tissue processing. We are eager to partner with leading companies to address key challenges to sample prep in solid tumor research, As Dr. Iacobuzio-Donahue's lab demonstrates, the Singulator 100 and Tapestri together are a powerful solution enabling single-cell DNA sequencing at scale, in pancreatic cancer research and across a variety of tissue types." Yan Zhang, Ph.D., CEO of Mission Bio. The Singulator 100 has been an important tool for enabling single-cell sequencing in solid tissue, but cancer researchers have been unable to directly interrogate DNA, Tapestri is the only commercial platform capable of single-cell DNA analysis, and we're excited to offer this single automated pipeline connecting cell and nuclei prep to Tapestri's microfluidics-based workflow."
