The anabolic steroid stanozolol is a potent inhibitor of human MutT homolog 1
MutT homolog 1 (MTH1) is a member of the NUDIX superfamily of enzymes and is an anticancer drug target. We show that stanozolol (Stz), an anabolic steroid, is an unexpected nanomolar inhibitor of MTH1. The X‐ray crystal structure of the human MTH1–Stz complex reveals a unique binding scaffold that could be utilized for future inhibitor development ...

Tuberculosis remains a global health challenge and new therapeutic targets are required. Here, we characterized SseA, a sulfurtransferase from Mycobacterium tuberculosis involved in macrophage infection, and its interaction with the newly identified protein SufEMtb that activates SseA enzymatic activity.

Mapping DNA sequence to transcription factor binding energy in vivo.
Despite the central importance of transcriptional regulation in biology, it has proven difficult to determine the regulatory mechanisms of individual genes, let alone entire gene networks.

This work presents the characterization of MvoDUF2193, a Methanococcus voltae (Mvo) protein from the domain of unknown function (DUF) 2193 family. We demonstrate that MvoDUF2193 binds a single [4Fe–4S] cluster per subunit and that cluster occupancy regulates the transition from an apo tetramer to a [4Fe–4S] monomeric form. This structural transition is

Structurally specific thermal fluctuations identify functional sites for DNA transcription
We report results showing that thermally-induced openings of double stranded DNA coincide with the location of functionally relevant sites for transcription.

ERBIN limits epithelial cell plasticity via suppression of TGF‐β signaling
In breast and lung cancer patients, low ERBIN expression correlates with poor clinical outcomes. Here, we show that ERBIN inhibits TGF‐β‐induced epithelial‐to‐mesenchymal transition in NMuMG breast and A549 lung adenocarcinoma cell lines. ERBIN suppresses TGF‐β/SMAD signaling and reduces TGF‐β‐induced ERK phosphorylation.

Scanning sequences after Gibbs sampling to find multiple occurrences of functional elements
Background Many DNA regulatory elements occur as multiple instances within a target promoter. Gibbs sampling programs for finding DNA regulatory elements de novo can be prohibitively slow in locating all instances of such an element in a sequence set ...

MEMOFinder: combining _de_ _novo_ motif prediction methods with a database of known motifs [PDF]
*Background:* Methods for finding overrepresented sequence motifs are useful in several key areas of computational biology. They aim at detecting very weak signals responsible for biological processes requiring robust sequence identification like ...

Neutrophil deficiency increases T cell numbers at the site of tissue injury in mice
In wild‐type mice, injury or acute inflammation induces neutrophil influx followed by macrophage accumulation. Mcl1ΔMyelo (neutrophil‐deficient) mice lack neutrophils, and in response to muscle injury show fewer macrophages and exhibit strikingly elevated T‐cell numbers, primarily non‐conventional “double‐negative” (DN) αβ and γδ T cells.

Edge usage, motifs and regulatory logic for cell cycling genetic networks
The cell cycle is a tightly controlled process, yet its underlying genetic network shows marked differences across species. Which of the associated structural features follow solely from the ability to impose the appropriate gene expression patterns?
