Machine learning reveals metabolic pathways disrupted by the drugs, offering new targets to combat resistance

phys.org | May 09, 2019

Most antibiotics work by interfering with critical functions such as DNA replication or construction of the bacterial cell wall. However, these mechanisms represent only part of the full picture of how antibiotics act. In a new study of antibiotic action, MIT researchers developed a new machine-learning approach to discover an additional mechanism that helps some antibiotics kill bacteria. This secondary mechanism involves activating the bacterial metabolism of nucleotides that the cells need to replicate their DNA. "There are dramatic energy demands placed on the cell as a result of the drug stress. These energy demands require a metabolic response, and some of the metabolic byproducts are toxic and help contribute to killing the cells," says James Collins, the Termeer Professor of Medical Engineering and Science in MIT's Institute for Medical Engineering and Science (IMES) and Department of Biological Engineering, and the senior author of the study.

The management of risk is part of all business operations, but to biotech companies manufacturing cell-based therapies, risk mitigation is necessarily a critical element of day-to-day operations. The costly nature of irreplaceable samples/cell lines and high value products such as cell-based drugs, and biological active pharmaceutical ingredient (Bio-API) dictates planning for the full continuum of risk. The best solution is frequently offsite storage. Choosing an offsite storage facility means asking the right questions.

Angstrom Bio Launches AMPD™, Platform for High-accuracy, High-frequency, Low-cost COVID-19 and Respiratory Pathogen Testing

Angstrom Bio | October 14, 2020

Angstrom Bio, Inc. today announces the launch of AMPD™, its nanopore sequencing and machine learning powered platform for high-accuracy, high-frequency, low-cost COVID-19 and respiratory pathogen testing. AMPD leverages the extreme resolution and bandwidth of nanopore sequencing to provide the accuracy and volume necessary to detect the earliest stages of exposure to pathogens like SARS-CoV-2 and influenza and to enable schools and places of work to reopen safely and confidently. Angstrom will partner with businesses, schools, and public sector organizations to implement cost-effective testing programs designed to maximize employee and stakeholder safety and to minimize the potential for operational disruption. The company intends to bring more than 1,000,000 results per day online in 2021, at prices that enable nearly any organization to have access to repeated, high-quality testing. "Despite the tremendous progress made in diagnostics since the beginning of the pandemic, it is clear that testing today remains an area plagued by too many tradeoffs between availability, accuracy, and speed, as well as ease of collection, cost, and adaptability," said Carlos F. Santos, Ph.D., Angstrom's CEO. "We designed AMPD to eliminate the need for such tradeoffs. By leveraging the extraordinary resolution and bandwidth of nanopore sequencing and the power of our machine learning-driven diagnostic pipelines, and by rethinking pre-COVID-19 diagnostic workflows, we have been able to design a platform that can provide the extreme scale and accuracy required to meet the unprecedented challenges posed by COVID-19." At the heart of AMPD is a novel nucleotide chemistry and computational biology platform designed to harness the bandwidth and resolution of Oxford Nanopore Technologies' nanopore Third-Generation Sequencing (TGS) systems. Unlike diagnostic systems that rely upon fluorescence-driven workflows for diagnostic analysis, nanopore TGS counts individual DNA molecules that pass through each of hundreds of nano-scale pores in a specially-designed membrane. The combination of single-molecule resolution and parallelism allow for the processing of tens of thousands of diagnostic results per AMPD run, while enabling orders of magnitude greater sensitivity than is currently available. This makes AMPD ideal for parties that require timely access to affordable, repeated testing, but that cannot compromise safety.
