Aspartate signalling drives lung metastasis via alternative translation.

Lung metastases occur in up to 54% of patients with metastatic tumours. Contributing factors to this high frequency include the physical properties of the pulmonary system and a less oxidative environment that may favour the survival of cancer cells. Moreover, secreted factors from primary tumours alter immune cells and the extracellular matrix of the lung, creating a permissive pre-metastatic environment primed for the arriving cancer cells.

Do Risk Factors for HCC Impact the Association of CT/MRI LIRADS Major Features With HCC? An Individual Participant Data Meta-Analysis.

Guidelines suggest the Liver Imaging Reporting and Data System (LI-RADS) may not be applicable for some populations at risk for hepatocellular carcinoma (HCC). However, data assessing the association of HCC risk factors with LI-RADS major features are lacking. To evaluate whether the association between HCC risk factors and each CT/MRI LI-RADS major feature differs among individuals at-risk for HCC.

A literature review of artificial intelligence (AI) for medical image segmentation: from AI and explainable AI to trustworthy AI.

Background And Objective: Medical image segmentation is a vital aspect of medical image processing, allowing healthcare professionals to conduct precise and comprehensive lesion analyses. Traditional segmentation methods are often labor intensive and influenced by the subjectivity of individual physicians. The advent of artificial intelligence (AI) has transformed this field by reducing the workload of physicians, and improving the accuracy and efficiency of disease diagnosis.

Paying to publish: A cross-sectional analysis of article processing charges and journal characteristics among 87 pathology journals.

Article processing charges are increasingly being levied on authors via publication fees to provide open access to readers. These charges may impose challenges to early career physicians seeking to publish research but pathology journal article processing charges have not been investigated to date. We aimed to quantify pathology journal article processing charges and investigate the potential associated factors.

Selective autophagy receptor hinders antitumor immunity.

Autophagy has a dual role in tumor progression and therapy, influenced by specific receptors and cargo selection. Recent research published in Cell by Herhaus et al. identifies immunity-related GTPase Q (IRGQ) as a novel autophagy receptor that facilitates immune evasion in hepatocellular carcinoma (HCC) by degrading histocompatibility complex class I (MHC-I) molecules, highlighting a potential target to enhance immunotherapy.

NFE2L2 and SLC25A39 drive cuproptosis resistance through GSH metabolism.

Cuproptosis is a recently discovered form of regulated cell death triggered by mitochondrial copper accumulation and proteotoxic stress. Here, we provide the first evidence that glutathione (GSH), a major non-protein thiol in cells, acts as a cuproptosis inhibitor in pancreatic ductal adenocarcinoma (PDAC) cells. Mechanistically, GSH inhibits cuproptosis by chelating copper, contrasting its role in blocking ferroptosis by inhibiting lipid peroxidation.

Comprehensive characterization of neddylation related genes in cutaneous melanoma identified a novel prognostic signature for treatment outcomes, immune landscape.

Neddylation, as a post-translational modification, has garnered significant attention in various tumor types recently. Few studies have investigated the involvement of neddylation-related genes (NRGs) in cutaneous melanoma (CM). Our study aims to identify prognostic NRGs and investigate their potential roles in CM.

TRIM32 inhibits Venezuelan equine encephalitis virus infection by targeting a late step in viral entry.

Alphaviruses are mosquito borne RNA viruses that are a reemerging public health threat. Alphaviruses have a broad host range, and can cause diverse disease outcomes like arthritis, and encephalitis. The host ubiquitin proteasome system (UPS) plays critical roles in regulating cellular processes to control the infections with various viruses, including alphaviruses.

Liver cancer in 2021: Global burden of disease study.

Background & Aims: The epidemiology of adult primary liver cancer continues to evolve, owing to the increasing prevalence of metabolic disease, rising alcohol consumption, advances in vaccination for HBV, and antiviral therapy for HCV. Disparities in care and the burden of liver cancer between populations persist. We assess trends in the burden of liver cancer and contributions by various etiologies across 204 countries and territories from 2010 to 2021.

Molecular model of a bacterial flagellar motor reveals a "parts-list" of protein adaptations to increase torque.

One hurdle to understanding how molecular machines work, and how they evolve, is our inability to see their structures . Here we describe a minicell system that enables cryogenic electron microscopy imaging and single particle analysis to investigate the structure of an iconic molecular machine, the bacterial flagellar motor, which spins a helical propeller for propulsion. We determine the structure of the high-torque motor including the subnanometre-resolution structure of the periplasmic scaffold, an adaptation essential to high torque.

Loss of LRP1 Promotes Hepatocellular Carcinoma Progression via UFL1-Mediated Activation of NF-κB Signaling.

Low-density lipoprotein receptor-related protein-1 (LRP1) is thought to be correlated with hepatocellular carcinoma (HCC) invasion and metastasis. However, the precise mechanism through which LRP1 contributes to HCC progression remains unclear. Here, lower LRP1 levels are associated with malignant progression, and poor prognosis in patients with HCC is shown.

Advances and Challenges in RAS Signaling Targeted Therapy in Leukemia.

RAS mutations are prevalent in leukemia, including mutations at G12, G13, T58, Q61, K117, and A146. These mutations are often crucial for tumor initiation, maintenance, and recurrence. Although much is known about RAS function in the last 40 years, a substantial knowledge gap remains in understanding the mutation-specific biological activities of RAS in cancer and the approaches needed to target specific RAS mutants effectively.

Combinatorial responsiveness of single chemosensory neurons to external stimulation of mouse explants revealed by DynamicNeuronTracker.

Calcium fluorescence imaging enables us to investigate how individual neurons of live animals encode sensory input or drive specific behaviors. Extracting and interpreting large-scale neuronal activity from imaging data are crucial steps in harnessing this information. A significant challenge arises from uncorrectable tissue deformation, which disrupts the effectiveness of existing neuron segmentation methods.

GV-971 prevents severe acute pancreatitis by remodeling the microbiota-metabolic-immune axis.

Despite recent advances, severe acute pancreatitis (SAP) remains a lethal inflammation with limited treatment options. Here, we provide compelling evidence of GV-971 (sodium oligomannate), an anti-Alzheimer's medication, as being a protective agent in various male mouse SAP models. Microbiome sequencing, along with intestinal microbiota transplantation and mass cytometry technology, unveil that GV-971 reshapes the gut microbiota, increasing Faecalibacterium populations and modulating both peripheral and intestinal immune systems.

RIPK4 promotes oxidative stress and ferroptotic death through the downregulation of ACSM1.

One of the most critical axes for cell fate determination is how cells respond to excessive reactive oxygen species (ROS)-oxidative stress. Extensive lipid peroxidation commits cells to death via a distinct cell death paradigm termed ferroptosis. However, the molecular mechanism regulating cellular fates to distinct ROS remains incompletely understood.

Mechanism of TBK1 activation in cancer cells.

TANK-binding kinase 1 (TBK1) is a serine/threonine kinase with well-established roles as a central player in innate immune signaling. Dysregulation of TBK1 activity has been implicated in a variety of pathophysiologic conditions, including cancer. Generally, TBK1 acts as an oncogene and increased TBK1 activity, indicated by increased phosphorylation at the Ser172 residue, can be observed in multiple human cancers.
