- Profiles of histidine-rich glycoprotein associate with age and risk of all-cause mortality
Affinity-based proteomics assays identify particular profiles of the circulating histidine-rich glycoprotein to increase with age and elevated levels to indicate a higher risk of all-cause mortality.
- Sam68 splicing regulation contributes to motor unit establishment in the postnatal skeletal muscle
Sam68 ensures the establishment of neuromuscular junctions (NMJs) and motor unit integrity by orchestrating a neuronal splicing program.
- Peptide-based quorum sensing systems in Paenibacillus polymyxa
Discovery of conserved communication systems in the agriculturally important Paenibacillus bacteria. These systems are widespread, and some species encode more than 25 different peptide-receptor pairs.
- Exploiting somatic piRNAs in Bemisia tabaci enables novel gene silencing through RNA feeding
RNAi usually relies on Dicer-produced siRNAs to induce gene silencing. In many arthropods, another type of RNAi is present in the soma—the piRNA pathway. This work finds exploiting this biology is a viable alternative for gene knockdown.
- Evolutionary divergence reveals the molecular basis of EMRE dependence of the human MCU
Using clues from evolution, chimeric proteins, and biochemical methods, this work identifies a new domain in mitochondrial calcium uniporter that determines its dependence on its binding partner EMRE.
- The bacterial quorum sensing signal DSF hijacks Arabidopsis thaliana sterol biosynthesis to suppress plant innate immunity
This study highlights that DSF, the quorum sensing signal produced by bacterial phytopathogens, is able to directly modulate plant plasma membrane dynamics by interfering with host lipid profile and thereby, suppress plant immunity responses.
- MIC26 and MIC27 cooperate to regulate cardiolipin levels and the landscape of OXPHOS complexes
Apolipoproteins of MICOS, MIC26 and MIC27, cooperatively manage cristae structure, cardiolipin levels, and the global stability and integrity of respiratory chain supercomplexes and F1Fo–ATP synthase.
- Thymosin α1 protects from CTLA-4 intestinal immunopathology
This study demonstrates that Tα1 protects mice from anti–CTLA-4–induced colitis and sustains its antitumor activity, thus suggesting that Tα1 may be used in combination protocols.
- DDX5 promotes oncogene C3 and FABP1 expressions and drives intestinal inflammation and tumorigenesis
In intestinal epithelial cells (IECs), DDX5 promotes the expression of immune response genes and oncogenes posttranscriptionally and is a novel therapeutic target for treating colitis and intestinal cancers.
- The RECQL helicase prevents replication fork collapse during replication stress
This work shows that RECQL is an essential player in the protection of stalled replication forks and possibly the restart of broken replication forks, thereby representing a target for cancer therapy.
- A dichotomy of gene regulatory associations during the activated B-cell to plasmablast transition
As human B-cells differentiate, IRF4 switches occupancy and acquires CTCF colocalisation and IRF4 regulatory output diverts from cell activation to plasma cell state genes in conjunction with XBP1, whereas BLIMP1 represses activation.

- Genome-wide R-loop analysis defines unique roles for DDX5, XRN2, and PRMT5 in DNA/RNA hybrid resolution
Genome-wide analysis of R-loop alterations in U2OS cells deficient of DDX5, XRN2, and PRMT5 identify >50,650 DRIP-seq peaks spanning ∼4.5% of the genomic sequence. R-loops near TSS generated intergenic antisense transcription.
