TREX1, a predator for treating MSI‐H tumors?

Molecular Oncology, EarlyView.
Immunotherapy benefits many patients; yet, some with MSI‐H tumors remain unresponsive despite their high immunogenicity. Xu et al. reveal that TREX1 enables immune evasion by degrading cytosolic DNA and suppressing cGAS–STING–IFN‐I signaling. TREX1 loss restores DNA sensing, increases CD8+ T and NK cell infiltration, and boosts antitumor immunity ...

Macrophage‐derived MLKL in alcohol‐associated liver disease: Regulation of phagocytosis

Hepatology, EarlyView., 2022
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

Insulin Action on Polyunsaturated Phosphatidic Acid Formation in Rat Brain: An “In Vitro” Model with Synaptic Endings from Cerebral Cortex and Hippocampus [PDF]

, 2009
The highly efficient formation of phosphatidic acid from exogenous 1-stearoyl-2-arachidonoyl-sn-glycerol (SAG) in rat brain synaptic nerve endings (synaptosomes) from cerebral cortex and hippocampus is reported.

Actin dynamics controlled by IqgC, a RasGAP at the crossroads between the IQGAP and fungal GAP1 families

FEBS Open Bio, EarlyView.
IqgC is a RasGAP from Dictyostelium discoideum. IqgC binds RasG via its RasGAP domain and deactivates it on macroendocytic cups, thereby suppressing the uptake of fluid and particles. IqgC has a positive effect on cell‐substratum adhesion, and its RGCt domain is required for recruitment to ventral foci.

Tubulins in C. elegans [PDF]

, 2018
The C. elegans tubulin family is composed of nine α-, six β-, and one γ-tubulin. Tubulins are highly conserved, functioning as α-β heterodimers that assemble into microtubules.

GTP binding and intramolecular regulation by the ROC domain of Death Associated Protein Kinase 1

Scientific Reports, 2012
The ROCO proteins are a family of large, multidomain proteins characterised by the presence of a Ras of complex proteins (ROC) domain followed by a COR, or C-terminal of ROC, domain.

Ethylene Regulates Monomeric GTP-Binding Protein Gene Expression and Activity in Arabidopsis [PDF]

Plant Physiology, 2003
AbstractEthylene rapidly and transiently up-regulates the activity of several monomeric GTP-binding proteins (monomeric G proteins) in leaves of Arabidopsis as determined by two-dimensional gel electrophoresis and autoradiographic analyses. The activation is suppressed by the receptor-directed inhibitor 1-methylcyclopropene.

Molecular determinants of signal transduction in tropomyosin receptor kinases

FEBS Open Bio, EarlyView.
Tropomyosin receptor kinases control critical neuronal functions, but how do the same receptors produce diverse cellular responses? This review explores the structural mechanisms behind Trk signaling diversity, focusing on allosteric modulation and ligand bias.

Small GTP-binding protein Rho-mediated signaling promotes proliferation of rheumatoid synovial fibroblasts [PDF]

, 2005
Rho is a major small GTP-binding protein that is involved in the regulation of various cell functions, including proliferation and cell migration, through activation of multiple signaling molecules in various types of cells.

Pathogenic Neurofibromatosis type 1 gene variants in tumors of non‐NF1 patients and role of R1276

FEBS Open Bio, EarlyView.
Somatic variants of the neurofibromatosis type 1 (NF1) gene occur across neoplasms without clinical manifestation of the disease NF1. We identified emerging somatic pathogenic NF1 variants and hotspots, for example, at the arginine finger 1276. Those missense variants provide fundamental information about neurofibromin's role in cancer.
