The B30.2/SPRY-Domain: A Versatile Binding Scaffold in Supramolecular Assemblies of Eukaryotes

Crystals
B30.2 domains, sometimes referred to as PRY/SPRY domains, were originally identified by sequence profiling methods at the gene level. The B30.2 domain comprises a concanavalin A-like fold consisting of two twisted seven-stranded anti-parallel β-sheets ...

H4K12 Lactylation Impairs Dopaminergic Neuron Energy Metabolism via the HIF‐1α/NDUFS1 Pathway in Parkinson's Disease

Advanced Science, EarlyView.
Lactate and H4K12la are elevated in Parkinson's disease. Mechanistically, p300‐mediated H4K12la enrichment at the HIF‐1α promoter upregulates HIF‐1α, which represses Ndufs1, impairing mitochondrial respiration and energy homeostasis in DA neurons.

The Antidepressant Mirtazapine Inhibits Hepatic Innate Immune Networks to Attenuate Immune-Mediated Liver Injury in Mice

Frontiers in Immunology, 2019
Activation of the innate immune system, including tissue macrophages and associated neutrophil infiltration, is an important driver of subsequent adaptive immune responses in many autoimmune diseases, including autoimmune hepatitis (AIH).

Disabling COMPASS Promoter Licensing Shifts HDAC‐Inhibited Gastric Cancer Toward Sustained Transcriptional Suppression During Recovery

Advanced Science, EarlyView.
Combined inhibition of the WDR5 WIN pocket and HDAC activity converts SAHA‐induced hyperacetylation into a promoter state with reduced WDR5–COMPASS association and H3K4me3. MYC/E2F‐linked nascent transcription and biosynthetic recovery are suppressed, while apoptosis and senescence‐like features increase, resulting in sustained growth inhibition in ...

The effect of concanavalin A on the replication of rotavirus (SA-11) in cell culture

Brazilian Archives of Biology and Technology, 2002
Rotavirus (RV) strain SA-11 was studied with respect to its infectivity in MA-104 cell cultures and the effect of concanavalin A (ConA). Receptors for ConA at the surface of MA-104 cell were determined by fluorescence assay and specifically inhibited by ...

Dopamine D2 Receptor-Mediated AKT/PKB Signalling: Initiation by the D2S Receptor and Role in Quinpirole-Induced Behavioural Activation

ASN Neuro, 2012
The short and long isoforms of the dopamine D2 receptor (D2S and D2L respectively) are highly expressed in the striatum. Functional D2 receptors activate an intracellular signalling pathway that includes a cAMP-independent route involving Akt/GSK3 ...

Thioredoxin‐2 Alleviates Osteoporosis by Restraining FOXO3a Nuclear Translocation

Advanced Science, EarlyView.
Endothelial TRX2 preserves bone homeostasis by retaining FOXO3a at mitochondria and limiting TRAIL production. Loss of TRX2 or oxidative stress releases FOXO3a for nuclear translocation, increasing endothelial TRAIL secretion and driving osteoclast formation and bone loss.

Maternal Hyperglycemia Disrupts Cerebral Cortex Development Through the Foxp1‐Dll1‐Notch Axis

Advanced Science, EarlyView.
Maternal hyperglycemia disrupts offspring cortical development through a Foxp1–Dll1–Notch signaling axis. In a PGDM mouse model, intrauterine hyperglycemia decreases cortical thickness and perturbs neuronal layering by downregulating Foxp1, which transcriptionally regulates the Notch ligand Dll1.

HECTD1 Directs HIF‐1α to Facilitate Intestinal Inflammation and Carcinogenesis via Promoting Th17 Differentiation and Glycolysis

Advanced Science, EarlyView.
HECTD1 emerges as an upstream amplifier of Th17 metabolic programming by promoting K63‐linked ubiquitination of IGF2BP3 and enhancing HIF‐1α translation. HIF‐1α reciprocally drives HECTD1 transcription, establishing a positive regulatory loop that sustains glycolysis and Th17 differentiation.

Vagal afferent fibers contribute to the anti-inflammatory reactions by vagus nerve stimulation in concanavalin A model of hepatitis in rats

Molecular Medicine, 2020
Background Increasing number of studies provide evidence that the vagus nerve stimulation (VNS) dampens inflammation in peripheral visceral organs. However, the effects of afferent fibers of the vagus nerve (AFVN) on anti-inflammation have not been ...
