Join @FredHutch.org's Basic Sciences Division as an Assistant or Associate Professor and help shape the future of fundamental biology. We welcome applicants whose work will complement, extend, or bring new directions to the division.

My lab at #Yale has two #riboswitch research openings: 1. Postdoc with mammalian gene manipulation experience (tinyurl.com/zzb269em); 2. Postdoc (or BS, MS) with bioinformatics skills (tinyurl.com/3j73jfcn). Send your cv to me or to Kavita at kumari.thakur@yale.edu.

(1/6) Thrilled to share this story! In our preprint from my PhD in the @kranzuschlab.bsky.social, with help from the Hatfull lab and @soreklab.bsky.social, we discover RyDEP, a phage-encoded RyR-domain glycosidase that allows phages to evade Thoeris defense. Highlights below! doi.org/10.64898/202...

Small RNA promotes negative feedback of the master virulence regulator PhoP by repressing the PhoQ sensor enhancer UgtL in acidic pH | mSphere

To cause disease, pathogens must express their virulence genes at the right time and in proper levels. Here, we establish that a small RNA (sRNA) restricts the activation of a regulator critical for t...

From lab reagent to metabolite: the riboswitch ligand guanidine as a relevant compound in bacterial physiology | Journal of Bacteriology

More than two decades ago, the first naturally occurring mRNA elements regulating gene expression by directly binding target ligands, termed riboswitches, were discovered in bacteria (1–4). Since then, more than 55 classes of riboswitches have been characterized (5, 6), advancing our general knowledge of gene regulation and stress response, but also unveiling unexpected biological roles for compounds whose relevance had remained elusive. A notable example is the discovery of riboswitches recognizing c-di-AMP and c-AMP-GMP (7, 8), which hinted at important biological functions for the two molecules that were later revealed to act as second messengers in key cellular processes such as biofilm formation, chemotaxis, sporulation, and virulence (9–11).

I’m excited to share some of the results of my postdoctoral work @yalemicropath.bsky.social, where we reveal how a mechanism of nutritional immunity deployed by macrophages against Salmonella governs their metabolic behavior inside host cells, just published @pnas.org: www.pnas.org/doi/10.1073/...

Enjoying this deep dive into the link between coffee and the microbiome They found a microbe (Lawsonibacter asaccharolyticus) that is 4- to 8-fold more abundant in coffee drinkers, and correlates with coffee intake in worldwide populations www.nature.com/articles/s41...

Coffee consumption is associated with intestinal Lawsonibacter asaccharolyticus abundance and prevalence across multiple cohorts - Nature Microbiology

Coffee consumption is associated with the presence and abundance of a specific member of the human gut microbiome, Lawsonibacter asaccharolyticus, and changes to the plasma metabolome.
