CONSERVED FUNCTIONAL DOMAINS OF THE RNA-POLYMERASE-III GENERAL TRANSCRIPTION FACTOR BRF [PDF]
In Saccharomyces cerevisiae, two components of the RNA polymerase III (Pol III) general transcription factor TFIIIB are the TATA-binding protein (TBP) and the B-related factor (BRF), so called because its amino-terminal half is homologous to the Pol II ...

Disturbed flow promotes the formation of TRIM21‐rich biomolecular droplets, which concentrate TRIM21 and PTPN14 and facilitate their SPRY‐FERM interaction (illustrated by the TRIM21 D355‐PTPN14 R132 salt bridge). This condensate‐driven proximity enables TRIM21 to catalyze K48‐linked polyubiquitination of PTPN14 at lysine 956, leading to proteasome ...

STAT1 promotes ferroptosis and inflammation in mouse hepatic ischemia-reperfusion injury
Hepatic ischemia reperfusion injury (HIRI) is a critical complication in liver surgery and transplantation, driven by excessive inflammation and hepatocellular death. Although ferroptosis is recognized as a major form of regulated cell death in HIRI, the

STAT1 interacts with RXRα to upregulate ApoCII gene expression in macrophages.
Apolipoprotein CII (apoCII) is a specific activator of lipoprotein lipase and plays an important role in triglyceride metabolism. The aim of our work was to elucidate the regulatory mechanisms involved in apoCII gene modulation in macrophages.

Non-Canonical Role of IKKα in the Regulation of STAT1 Phosphorylation in Antiviral Signaling. [PDF]
Non-self RNA is recognized by retinoic acid-inducible gene-I (RIG-I)-like receptors (RLRs), inducing type I interferons (IFNs). Type I IFN promotes the expression of IFN-stimulated genes (ISGs), which requires the activation of signal transducer and ...

Transcription factor complex formation and chromatin fine structure alterations at the murine c-fms (CSF-1 receptor) locus during maturation of myeloid precursor cells [PDF]
Expression of the gene for the macrophage colony stimulating factor receptor (CSF-1R), c-fms, has been viewed as a hallmark of the commitment of multipotent precursor cells to macrophages.

Selective Modulation of OTUB1 Noncanonical Function via a bioPhosTAC Strategy
This work positions the versatile performance of the peptide‐based bioPhosTAC platform for dissecting phosphorylation‐dependent biology and expanding the scope of induced‐proximity technologies. We demonstrated that selective manipulation of a tyrosine phosphorylation site is sufficient to propagate coordinated cellular consequences.

Macrophage‐derived MLKL in alcohol‐associated liver disease: Regulation of phagocytosis
EtOH causes leaky gut allowing bacteria and PAMPs into the liver, resulting in hepatic inflammation and injury. We demonstrate that LPS induces STAT1‐mediated expression and phosphorylation of MLKL in macrophages and identify a novel function that myeloid MLKL translocates to phagosomes and lysosomes and regulates phagocytosis, which contributes to the

Macrophage PABPC4‐SPP1 Axis Orchestrates Immunosuppression in Colorectal Cancer
In the CRC microenvironment, macrophage PABPC4 binds to the 3′UTR of SPP1 mRNA to stabilize its expression, thereby sustaining M2‐like immunosuppressive macrophage polarization. Concurrently, this axis suppresses CD8+ T cell effector functions via CD44 signaling, collectively fostering an immunosuppressive niche that drives tumor progression.
