Proteogenomics reveals markers of chemotherapy resistance and outcome in triple negative breast cancer

Broad Institute

Data from standard DNA and RNA sequencing approaches were integrated with mass spectrometry-based proteomics and phosphoproteomic analyses to derive more complete molecular portraits of treatment-responsive versus treatment-resistant tumors. "The These data suggest a multi-omics predictor for chemotherapy response is within reach.

A Look Back

Dark Matter Blog

As soon as I learned about DNA and RNA, I wanted to be a molecular biologist. Last stops at RNA My last roles in biotech were where my original passion began: DNA and RNA. As any good idea tends to have a long life, Ad-IFN is currently in a phase 3 clinical trial in mesothelioma patients.

Article FDA Thank You Draft guidance on potency assays for CGT products garners extensive stakeholder input

Agency IQ

Not only are assays useful tools for characterizing products early in development; they can also be used to set “benchmarks,” allowing sponsors to verify that the lots of the product used during clinical trials and eventually, for commercial distribution, continue to adhere to the same standards specified in the original product’s design.

Digital nanoreactors to control absolute stoichiometry and spatiotemporal behavior of DNA receptors within lipid bilayers. Peroxisomal metabolic coupling improves fatty alcohol production from sole methanol in yeast. Optogenetic closed-loop feedback control of the unfolded protein response optimizes protein production.

Beyond Steel Tanks

Codon

Credit: Universität Würzburg Archives His key insight hinged upon the fact that living cells are essentially bags of liquid filled with enzymes, or proteins that speed up chemical reactions. Water accounts for 70 percent of a bacterium by mass; the other 30 percent includes everything else: proteins, RNA, DNA, lipids, and so on.

An “Unsilencer” Drug May Treat Angelman Syndrome – Someday

PLOS: DNA Science

This part of chromosome 15 is especially unstable because highly repetitive DNA sequences bracket the genes associated with the symptoms. Repeats can cause slippage as DNA replicates. The researchers scrutinized a “chemogenetic library ,” which is a collection of chemical compounds that bind to specific DNA sequences.

Codon Digest: Discovering Antibiotics with Deep Learning

Codon

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. An engineered version of this protein can convert DNA bases with efficiencies up to 92%. so this Digest will be published more irregularly.
