Regulated nuclear import of the STAT1 transcription factor by direct binding of importin-alpha [PDF]
Signal transducers and activators of transcription (STATs) reside in a latent state in the cytoplasm of the cell, but accumulate in the nucleus in response to cytokines or growth factors. Localization in the nucleus occurs following STAT tyrosine phosphorylation and dimerization.

Signal transducer and activator of transcription-1 localizes to the mitochondria and modulates mitophagy [PDF]
The signal transducer and activator of transcription (STAT) proteins are latent transcription factors that have been shown to be involved in cell proliferation, development, apoptosis, and autophagy. STAT proteins undergo activation by phosphorylation at

Signal transducer and activator of transcription 2 deficiency is a novel disorder of mitochondrial fission [PDF]
Defects of mitochondrial dynamics are emerging causes of neurological disease. In two children presenting with severe neurological deterioration following viral infection we identified a novel homozygous STAT2 mutation, c.1836C4A (p.Cys612Ter), using ...

Molecular mechanisms of IL-18BP regulation in DLD-1 cells: pivotal direct action of the STAT1/GAS axis on the promoter level [PDF]
Interleukin (IL)-18, formerly known as interferon (IFN)-γ-inducing factor, is a crucial mediator of host defence and inflammation. Control of IL-18 bioactivity by its endogenous antagonist IL-18 binding protein (IL-18BP) is a major objective of ...

SUMO conjugation of STAT1 protects cells from hyperresponsiveness to IFNγ [PDF]
The biologic effects of IFNγ are mediated by the transcription factor STAT1. The activity of STAT1 is inhibited by small ubiquitin-like modifier (SUMO) conjugation.

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

Proteomic profile of KSR1-regulated signalling in response to genotoxic agents in breast cancer [PDF]
Kinase suppressor of Ras 1 (KSR1) has been implicated in tumorigenesis in multiple cancers, including skin, pancreatic and lung carcinomas. However, our recent study revealed a role of KSR1 as a tumour suppressor in breast cancer, the expression of which

Effects of hypnotic bromovalerylurea on microglial BV2 cells
An old sedative and hypnotic bromovalerylurea (BU) has anti-inflammatory effects. BU suppressed nitric oxide (NO) release and proinflammatory cytokine expression by lipopolysaccharide (LPS)-treated BV2 cells, a murine microglial cell line.
