Reaching cruising altitude: New discovery tools to target RNA

Dark Matter Blog

Our overall mission at Arrakis is to expand the set of “druggable” targets for small-molecule medicines to include RNA. Today, we are pleased to announce that our article describing one such platform: “ PEARL-seq, A Photoaffinity Platform for the Analysis of Small Molecule-RNA Interactions ” was published in ACS Chemical Biology.

Malaria unravelled: decoding the parasite’s gene expression control

Drug Target Review

Through phylogenetic analysis and microscopy techniques, they identified a nuclear-encoded apicoplast RNA polymerase σ subunit called ApSigma. The initial subject of my research carrier was RNA polymerase principal sigma factors in bacteria. The first identification was based on a bioinformatic analysis.

When doctors sequenced the DNA and RNA found in Alice’s blood and synovial fluid—the liquid that surrounds and lubricates joints—they found abnormally low levels of genes encoding iron-storing proteins and high levels of epidermal growth factor receptor RNA. At least nine laboratories outside the U.S.
