Loss of YTHDC1 mA reading function promotes invasiveness in urothelial carcinoma of the bladder.

Bladder cancer poses significant clinical challenges due to its high metastatic potential and poor prognosis, especially when it progresses to muscle-invasive stages. Here, we show that the mA reader YTHDC1 is downregulated in muscle-invasive bladder cancer and is negatively correlated with the expression of epithelial‒mesenchymal transition genes. The functional inhibition or depletion of YTHDC1 increased the migration and invasion of urothelial cells.

Assessment of Brain Development in Children With Congenital Diaphragmatic Hernia - an Automated Brain Segmentation Approach.

Background/aim: Congenital diaphragmatic hernia (CDH) is a critical condition affecting newborns, which often results in long-term morbidities, including neurodevelopmental delays, which affect cognitive, motor, and behavioral functions. These delays are believed to stem from prenatal and postnatal factors, such as impaired lung development and chronic hypoxia, which disrupt normal brain growth. Understanding the underlying mechanisms of these neurodevelopmental impairments is crucial for improving prognosis and patient outcomes, particularly as advances in treatments like ECMO have increased survival rates but also pose additional risks for neurodevelopment.

Prevention of Stroke in Intracerebral Haemorrhage Survivors with Atrial Fibrillation: Rationale and Design for PRESTIGE-AF Trial.

Adequate secondary prevention in survivors of intracerebral hemorrhage (ICH) who also have atrial fibrillation (AF) is a long-standing clinical dilemma because these patients are at increased risk of recurrent ICH as well as of ischemic stroke. The efficacy and safety of oral anticoagulation, the standard preventive medication for ischemic stroke patients with AF, in ICH patients with AF are uncertain. PRESTIGE-AF is an international, phase 3b, multi-center, randomized, open, blinded end-point assessment (PROBE) clinical trial that compared the efficacy and safety of direct oral anticoagulants (DOACs) with no DOAC (either no antithrombotic treatment or any antiplatelet drug).

Altering phosphorylation of dystrophin S3059 to attenuate cancer cachexia.

Aims: Cancer cachexia affects up to 80 % of patients with advanced cancer and accounts for >20 % of all cancer-related deaths. Sarcolemmal localization of dystrophin, a key protein within the dystrophin-glycoprotein complex (DGC), is perturbed in multiple muscle wasting conditions, including cancer cachexia, indicating a potential role for dystrophin in the maintenance of muscle mass. Strategies to preserve dystrophin expression at the sarcolemma might therefore combat muscle wasting.

Characterization of thyroid hormone transport in a human choroid plexus papilloma cell line (HIBCPP) as an in vitro blood-cerebrospinal fluid barrier model.

Adequate levels of thyroid hormones (THs) in the fetal brain are vital for early neurodevelopment. Most of TH in fetal brain is derived from circulating thyroxine (T4), which gets locally converted into the biologically active triiodothyronine (T3) by deiodinase enzymes. One of the major routes of TH into the brain is through the blood-cerebrospinal fluid barrier (BCSFB).

Professional-patient discrepancies in assessing lung cancer radiotherapy symptoms: An international multicentre study.

Background And Purpose: We investigate discrepancies in the assessment of treatment-related symptoms in lung cancer between healthcare professionals and patients, and factors contributing to these discrepancies.

Deciphering the role of the MALT1-RC3H1 axis in regulating GPX4 protein stability.

Ferroptosis, a unique form of iron-dependent cell death triggered by lipid peroxidation accumulation, holds great promise for cancer therapy. Despite the crucial role of GPX4 in regulating ferroptosis, our understanding of GPX4 protein regulation remains limited. Through FACS-based genome-wide CRISPR screening, we identified MALT1 as a regulator of GPX4 protein.

Membrane-embedded CdaA is required for efficient synthesis of second messenger cyclic di-AMP.

Cyclic di-adenylate monophosphate (cyclic di-AMP) is an important second messenger in microorganisms. Cyclic di-AMP regulates bacterial cell volume and turgor via control of potassium and compatible solute transport but is also involved in many other processes, including the activation of the metazoan innate immune response to bacterial infections. We compare the activity of full-length membrane-embedded CdaA, the enzyme that synthesizes cyclic di-AMP, with the water-soluble catalytic domain CdaA-DAC.
