Lactylation of HMGB1 at K177 Drives Nuclear Export of TIAR to Promote Hypoxia‐Induced Stress Granule Formation

Advanced Science, EarlyView.
This study uncovers a novel mechanism in which p300‑catalyzed lactylation of HMGB1 triggers nuclear export of the HMGB1‐TIAR complex, driving TIAR‐dependent SGs formation in the cytoplasm. Mass spectrometry and mutagenesis reveals that K177 lactylation is essential for this export and subsequent SGs formation.

Comparative structural dynamic analysis of GTPases.

PLoS Computational Biology, 2018
GTPases regulate a multitude of essential cellular processes ranging from movement and division to differentiation and neuronal activity. These ubiquitous enzymes operate by hydrolyzing GTP to GDP with associated conformational changes that modulate ...

Structure of UreG/UreF/UreH complex reveals how urease accessory proteins facilitate maturation of Helicobacter pylori urease. [PDF]

PLoS Biology, 2013
Urease is a metalloenzyme essential for the survival of Helicobacter pylori in acidic gastric environment. Maturation of urease involves carbamylation of Lys219 and insertion of two nickel ions at its active site. This process requires GTP hydrolysis and

Exocytosis from permeabilized bovine adrenal chromaffin cells is differently modulated by guanosine 5'-[gamma-thio]triphosphate and guanosine 5'-[beta gamma-imido]triphosphate [PDF]

, 1992
1. In bovine adrenal chromaffin cells made permeable either to molecules less than or equal to 3 kDa with alphatoxin or to proteins less than or equal to 150 kDa with streptolysin O, the GTP analogues guanosine 5'-[beta gamma-imido]triphosphate (p[NH]ppG)

Molecular Aspects of Secretory Granule Exocytosis by Neurons and Endocrine Cells [PDF]

, 1994
Neuronal communication and endocrine signaling are fundamental for integrating the function of tissues and cells in the body. Hormones released by endocrine cells are transported to the target cells through the circulation.

Igfbp2 Downregulation in PVT‐CeA Glutamatergic Circuits Drives Neonatal Anesthesia‐Induced Fear Memory Deficits

Advanced Science, EarlyView.
Repeated neonatal sevoflurane exposure impairs adolescent fear memory through Igfbp2 downregulation in paraventricular thalamus‐central amygdala glutamatergic projections. Restoring Igfbp2 or activating this circuit rescues memory deficits, neuronal excitability, and spine density, identifying a precise molecular target for preventing anesthesia ...

Malignant progression of liver cancer progenitors requires lysine acetyltransferase 7–acetylated and cytoplasm‐translocated G protein GαS

Hepatology, EarlyView., 2022
KAT7‐acetylated and cytoplasm‐translocated G‐protein GαS enhances IL‐6 effect and drives HCC progenitor cell progression. Abstract Background and Aims Hepatocarcinogenesis goes through HCC progenitor cells (HcPCs) to fully established HCC, and the mechanisms driving the development of HcPCs are still largely unknown.

Cell surface localization of tissue transglutaminase is dependent on a fibronectin-binding site in its N-terminal beta-sandwich domain [PDF]

, 1999
Increasing evidence indicates that tissue transglutaminase (tTG) plays a role in the assembly and remodeling of extracellular matrices and promotes cell adhesion.

Onion‐Mitochondria Inhibit Lipopolysaccharide‐Induced Acute Lung Injury by Shaping Lung Macrophage Mitochondrial Function

Advanced Science, EarlyView.
Proposed model of orally administered onion mitochondria (O‐Mit) uptake by lung macrophages and fuse with macrophage mitochondria (M‐Mit). This fusion reprograms the metabolism of dysfunctional M‐Mit in lipopolysaccharide‐induced murine acute lung injury by modulating dynamin‐related protein 1 (DRP1) phosphorylation and cardiolipin peroxidation ...
