KRAS/ABHD17C/ALOX15B Axis Promotes Pancreatic Cancer Progression via Ferroptosis Evasion

open access: yesAdvanced Science, EarlyView.
Phosphorylation of ABHD17C induced by KRASmut/ERK signaling facilitates ALOX15B depalmitoylation and degradation via the CUL4/DDB1/DCAF10 complex, thereby enabling KRASmut‐PDAC cell to evade ferroptosis. Methyl protodioscin inhibits KRASmut‐PDAC progression by disrupting the ABHD17C/ALOX15B interaction and inducing ferroptosis, which represents a ...

Dynamic cofilin phosphorylation in the control of lamellipodial actin homeostasis [PDF]

open access: yes, 2007
During animal cell chemotaxis, signalling at the plasma membrane induces actin polymerisation to drive forward cell movement. Since the cellular pool of actin is limited, efficient protrusion formation also requires the coordinated disassembly of pre ...

The architecture of the Rag GTPase signaling network [PDF]

open access: yes, 2017
The evolutionarily conserved target of rapamycin complex 1 (TORC1) couples an array of intra- and extracellular stimuli to cell growth, proliferation and metabolism, and its deregulation is associated with various human pathologies such as ...

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

open access: yesAdvanced 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.

Novel regulation of mitotic exit by the Cdc42 effectors Gic1 and Gic2 [PDF]

open access: yes, 2004
Copyright @ The Rockefeller University PressThe guanine nucleotide exchange factor Cdc24, the GTPase Cdc42, and the Cdc42 effectors Cla4 and Ste20, two p21-activated kinases, form a signal transduction cascade that promotes mitotic exit in yeast.

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

open access: yesAdvanced 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 ...

Expression of MHC II genes

open access: yes, 2005
Innate and adaptive immunity are connected via antigen processing and presentation (APP), which results in the presentation of antigenic peptides to T cells in the complex with the major histocompatibility (MHC) determinants.

The importance of the GTP‐binding protein tissue transglutaminase in the regulation of cell cycle progression

open access: yesFEBS Letters, 1995
Tissue transglutaminase (tTgase) is a GTP‐binding Ca2+‐dependent enzyme which catalyses the post‐translational modification of proteins via ϵ(γ‐glutamyl) lysine bridges. Recent evidence suggests that the GTP‐binding activity of tTgase may be important in intracellular signalling thus explaining some of the diverse suggested roles for the enzyme. In the

An Amygdala‐hippocampus Circuit for Endocannabinoid Modulation of Anxiety Avoidance

open access: yesAdvanced Science, EarlyView.
This study employs three synapse‐specific endocannabinoids (eCB) probes to monitor dynamic eCB release, activate CB1Rs and knockdown 2‐AG biosynthesis enzymes in glutamatergic anterior basolateral amygdala ‐ ventral hippocampus (aBLA–vHPC) circuit. At aBLA–vHPC circuits, activation of CB1Rs reduce anxiety avoidance, and knockdown of eCB biosynthesis ...

The GAPs, GEFs, and GDIs of heterotrimeric G-protein alpha subunits

open access: yesInternational Journal of Biological Sciences, 2005
The heterotrimeric G-protein alpha subunit has long been considered a bimodal, GTP-hydrolyzing switch controlling the duration of signal transduction by seven-transmembrane domain (7TM) cell-surface receptors.
