Cyclic AMP metabolism and adenylate cyclase concentration in patients with advanced hepatic cirrhosis [PDF]

open access: yes, 1978
Glucagon was tested for its effect on plasma adenosine 3′,5′-cyclic monophosphate (cyclic AMP), insulin, and glucose in healthy subjects and in patients with advanced cirrhosis of the liver. In the normal subjects, intravenous infusion of glucagon caused

Xylose Metabolism Perturbation in Yarrowia lipolytica for Efficient Succinic Acid Bioproduction from Lignocellulosic Biomass

open access: yesAdvanced Science, EarlyView.
This study engineers Yarrowia lipolytica to produce succinic acid (SA) from lignocellulosic biomass. Adaptive evolution and multi‐omics analysis identify regulators that alleviate xylose metabolic disorder. Multi‐copy integration of xylose metabolic genes resolves redox imbalances from a futile fatty acid cycle, producing high‐titer SA from corn stover

Targeting Histamine H4 Receptor in the Rostral Ventromedial Medulla to Relieve Hypertension

open access: yesAdvanced Science, EarlyView.
H4R and its downstream TRPV1 channel mediate the excitatory effect of TMN histaminergic afferent inputs on GABAergic sympathoinhibitory neurons in RVMM. Intranasal delivery of selective H4R agonist VUF 8430 suppresses renal sympathetic outflow and elicits sustained depressor and bradycardia responses in SHRs and CUMS‐induced hypertensive rats ...

Steady-state modulation of voltage-gated K+ channels in rat arterial smooth muscle by cyclic AMP-dependent protein kinase and protein phosphatase 2B [PDF]

open access: yes, 2015
Voltage-gated potassium channels (Kv) are important regulators of membrane potential in vascular smooth muscle cells, which is integral to controlling intracellular Ca2+ concentration and regulating vascular tone. Previous work indicates that Kv channels

Cyclic AMP-Dependent Protein Kinase A Regulates the Alternative Splicing of CaMKIIδ

open access: yesPLoS ONE, 2011
Ca(2+)/calmodulin-dependent protein kinase (CaMK) IIδ is predominantly expressed in the heart. There are three isoforms of CaMKIIδ resulting from the alternative splicing of exons 14, 15, and 16 of its pre-mRNA, which is regulated by the splicing factor SF2/ASF. Inclusion of exons 15 and 16 or of exon 14 generates δA or δB isoform. The exclusion of all

Smohaze‐Upregulated RFWD3 Competes with TRIM24 to Stabilize TREX1 and Reduce Cytosolic dsDNA in Non‐Small Cell Lung Cancer

open access: yesAdvanced Science, EarlyView.
The E3 ubiquitin ligase RFWD3 binds the exonuclease TREX1 and protects it from TRIM24‐mediated ubiquitination and degradation, leading to the eradication of intracellular dsDNA, inhibition of the cGAS‐STING pathway, and immunosuppressive microenvironment of lung cancer.

An evolutionary perspective on the kinome of malaria parasites [PDF]

open access: yes, 2012
Malaria parasites belong to an ancient lineage that diverged very early from the main branch of eukaryotes. The approximately 90-member plasmodial kinome includes a majority of eukaryotic protein kinases that clearly cluster within the AGC, CMGC, TKL ...

Blocking Lysine Crotonylation and Aerobic Glycolysis as Targeting Strategy Against mpox Virus Replication

open access: yesAdvanced Science, EarlyView.
Wei et al. report that MPXV infection induces aerobic glycolysis, a process mediated by the viral protein I3 through lysine crotonylation at its K102 residue. The acetyltransferase MYST1 catalyzes the crotonylation of I3 to inhibit the ubiquitin‐mediated degradation of WDR26.
