Edwardsiella piscicida effector EseD mediates ferritinophagy by targeting NCOA4 and STING in teleost cells.

Edwardsiella piscicida (E. piscicida), an important pathogen in aquatic systems, has been demonstrated to hijack Ncoa4 (nuclear receptor co-activator 4)-dependent ferritinophagy through its type III secretion system effector EseD, thereby promoting intracellular bacterial survival. However, the molecular mechanisms governing EseD-mediated ferritinophagy remain elusive.

Suppression of NRAS-mutant melanoma growth with NRAS-targeting Antisense Oligonucleotide treatment reveals therapeutically relevant kinase co-dependencies.

Background: Melanoma is an aggressive form of skin cancer, and patients with NRAS-mutant melanoma face limited treatment options due to the lack of direct NRAS inhibitors. This study explores the utilization of antisense oligonucleotides (ASOs) to directly target NRAS-mRNA for therapeutic approaches.

Methods: We designed and tested NRAS-mRNA-targeting ASOs.

Proton perception and activation of a proton-sensing GPCR.

Maintaining pH at cellular, tissular, and systemic levels is essential for human health. Proton-sensing GPCRs regulate physiological and pathological processes by sensing the extracellular acidity. However, the molecular mechanism of proton sensing and activation of these receptors remains elusive.

Impact of Frailty on Antihypertensive Treatment in Older Adults.

Background: The association between systolic blood pressure and all-cause mortality differs between frail and nonfrail individuals, highlighting uncertainties about the effectiveness of antihypertensive treatments in frail populations.

Methods: Using data from the SHEP trial (Systolic Hypertension in the Elderly Program), a baseline frailty index (FI), including 55 variables, was constructed. Fine-Gray subdistribution hazard models and Cox proportional hazards regression models were used to explore the association between baseline FI and the risks of stroke, cardiovascular disease, and all-cause death, as well as to examine whether the impact of antihypertensive treatment on these outcomes was modified by baseline FI.

Delayed open-heart operation to remove migrated intracardiac inferior vena cava stents in a living donor liver transplantation recipient: a case report.

Intracardiac migration of inferior vena cava (IVC) filter or stent is a rare but potentially fatal complication of endovascular venous device placement. There is no consensus whether migrated stents should be surgically removed by open cardiac surgery or retrieved by the percutaneous endovascular route and whether an intervention should be performed immediately or expectantly. Herein, we report a 39-year-old female who received emergent left lobe living donor liver transplantation (LDLT) owing to posthepatectomy liver failure.

Molecular insights into the activation mechanism of GPR156 in maintaining auditory function.

The class C orphan G-protein-coupled receptor (GPCR) GPR156, which lacks the large extracellular region, plays a pivotal role in auditory function through G. Here, we firstly demonstrate that GPR156 with high constitutive activity is essential for maintaining auditory function, and further reveal the structural basis of the sustained role of GPR156. We present the cryo-EM structures of human apo GPR156 and the GPR156-G complex, unveiling a small extracellular region formed by extracellular loop 2 (ECL2) and the N-terminus.

In situ synthesis of luminescent dsDNA-Cu NCs stained with a dsDNA-lighted fluorophore for rapid and stable detection of histamine in food.

Poisonous histamine is accumulated in stale meat and fermented foods. The rapid and stable detection of histamine is essential for food safety.

Orthosteric and allosteric modulation of human HCAR2 signaling complex.

Hydroxycarboxylic acids are crucial metabolic intermediates involved in various physiological and pathological processes, some of which are recognized by specific hydroxycarboxylic acid receptors (HCARs). HCAR2 is one such receptor, activated by endogenous β-hydroxybutyrate (3-HB) and butyrate, and is the target for Niacin. Interest in HCAR2 has been driven by its potential as a therapeutic target in cardiovascular and neuroinflammatory diseases.

Deconstructing the role of MALAT1 in MAPK-signaling in melanoma: insights from antisense oligonucleotide treatment.

The long non-coding RNA (lncRNA) MALAT1 is a regulator of oncogenesis and cancer progression. MAPK-pathway upregulation is the main event in the development and progression of human cancer, including melanoma and recent studies have shown that MALAT1 has a significant impact on the regulation of gene and protein expression in the MAPK pathway. However, the role of MALAT1 in regulation of gene and protein expression of the MAPK-pathway kinases RAS, RAF, MEK and ERK in melanoma is largely unknown.
