By training PLACER on structures stored in the Protein Data Bank, the team taught the model to predict atom arrangements that follow the physical and chemical rules governing protein-smallmolecule interactions. They synthesized DNA encoding each protein variant, expressed the proteins in E.
Dian eventually made her way to Shanghai, where she encountered a much bigger world while earning degrees in pharmaceutical engineering and medicinal chemistry. researching DNA photoproducts related to skin cancer. In her smallmolecule DMPK research, proteomics also served to identify reactive metabolites (e.g.,
Finding smallmolecule drugs is much harder than finding a needle in a haystack – discovering the right arrangement of atoms to bind precisely to a protein target to elicit a particular response is a problem of vast dimensionality. Yet the situation with smallmolecules is even worse.
And unlike traditional DNA sequencers, which parse genetic material by breaking it up into fragments and interpreting it chunk-by-chunk, a nanopore device unspools a long strand of DNA and reads it all at once. A scientist can isolate DNA and load up a flow cell in fifteen minutes. Nanopore devices work incredibly fast.
Columbia Engineering researchers report that they have developed a “cloaking” system that temporarily hides therapeutic bacteria from immune systems, enabling them to more effectively deliver drugs to tumors and kill cancer cells in mice. Sheng Professor of Biomedical Engineering. ” An Effective On/Off Switch.
Data Science in Lead Optimization and Drug Design Data science accelerates the lead optimization and drug design process, transforming how molecules are engineered for therapeutic applications. These complex molecules require precise engineering to ensure optimal efficacy and safety.
For my PhD project, I chose an advisor who worked on DNA and I started working with her on the physical properties of DNA. I worked with Jackie Barton in the early days of what’s now called DNA-mediated electron transfer. I went to Genentech and postdoc-ed for Jim Wells in protein engineering.
By delivering radiation directly to the tumour cells, RLT can induce DNA damage, leading to cell death and tumour regression. Peptides are relatively smallmolecules compared to mAbs, making them easier and less costly to produce and modulate. In contrast, development of mAbs is typically resource intensive.
The majority of smallmolecule drugs induce their therapeutic effects by seeking out and binding to their intended target while avoiding most other molecules in the dense milieu of the cell interior. Our overall mission at Arrakis is to expand the set of “druggable” targets for small-molecule medicines to include RNA.

This is Codon Digest, a weekly roundup of research papers, news articles, and industry highlights about engineered biology. But now, by studying DNA extracted from microbes in the blood of almost 10,000 healthy people, this paper shows that there is no such thing. Read Transcription factors bind to DNA and control gene expression.
Codon Digest is my weekly roundup of research, news, and industry highlights about engineered biology. This week: A way to measure a transgene’s expression in the brain using ultrasound, a DNA sequencing method that uses 1000x less reagents, and base editors get even smaller. Please send me your feedback. Thanks for reading.

New supercomputing-scale large language models (LLMs) that understand biology and chemistry text are helping scientists understand proteins, smallmolecules, DNA, and biomedical text. These state-of-the-art AI models help generate de novo proteins and molecules and predict the 3D structures of proteins.
DNA and RNA molecules are also built from exclusively right-handed nucleic acids. Glucose is a chiral molecule because its structure allows for two distinct configurations, or enantiomers, which cannot be superimposed on each other. The mirrored enzyme seamlessly transcribed 2,900 bases of mirrored DNA into mirrored RNA.
These hair clip-like molecules clamp onto DNA, thereby turning many genes on and off. As Darnell observed, the prospect of being able to regulate Transcription Factor function holds the potential to reframe the way we treat disease but achieving that goal with traditional smallmolecule screening approaches is impossible.

Engineering sites on the antibody to enable specific and consistent attachment of the cytotoxic drug to achieve an optimal drug-to-antibody ratio (DAR). Innovations in payload substances, such as topoisomerase inhibitors (topo-1i), and next-generation DNA- damaging agents to replace older, more toxic agents.
engine along with algorithms tuned to predict BBB permeability played an important role in helping determine which CNS cancers and which genomically-defined subtypes of CNS cancer should be prioritized for development. .
Many drugs fail in clinical trials because of their low blood brain barrier permeability. Lantern’s A.I.
In contrast, targeted therapies are engineered to exploit specific vulnerabilities in cancer cells, such as oncogenic mutations or irregular signaling pathways. This targeted therapy is a smallmolecule inhibitor of the BCR-ABL tyrosine kinase, the oncogenic driver of CML.

Avacopan is an oral smallmolecule selective inhibitor of the complement C5a receptor Cf1R1. platforms and the human GM-CSF cytokine.
Targeting Novel Bacterial Pathways Traditional antibiotics often target essential bacterial processes such as cell wall synthesis or DNA replication. Advances in genetic engineering have enabled researchers to enhance bacteriophage efficacy and overcome bacterial resistance mechanisms.
Srinivasan has led the development of multiple computational pipelines to process data from different next generation sequencing techniques with applications in oncology, genome editing systems including CRISPR-Cas mediated DNA editing, and ADAR-mediated RNA editing.
