RIOK3 sustains colorectal cancer cell survival under glucose deprivation via an HSP90α-dependent pathway.

Glucose oxidation via the pentose phosphate pathway serves as the primary cellular mechanism for generating nicotinamide adenine dinucleotide phosphate (NADPH). The central regions of solid tumors typically experience glucose deficiency, emphasizing the need for sustained NADPH production crucial to tumor cell survival. This study highlights the crucial role of RIOK3 in maintaining NADPH production and colorectal cancer (CRC) cell survival during glucose deficiency.

Hinokitiol protects gastric injury from ethanol exposure via its iron sequestration capacity.

Hinokitiol is a natural bioactive tropolone derivative isolated from Chamaecyparis obtusa and Thuja plicata, which exhibits promising potential in terms of antioxidant and anti-inflammatory properties and possesses potent iron-binding capacity. In this study, we aimed to investigate the potential role of hinokitiol in protecting against ethanol-induced gastric injury and elucidate the underlying mechanism. Our results demonstrated that hinokitiol effectively attenuated hemorrhagic gastric lesions, epithelial cell loss, and inflammatory response in mice with ethanol-induced gastric injury.

Precipitation changes and its interaction with terrestrial water storage determine water yield variability in the world's water towers.

Previous studies have quantified the contributions of climate factors, vegetation, and terrestrial water storage change, and their interaction effects on hydrological process variation within the Budyko framework; however, further decomposition of the contributions of water storage change has not been systematically investigated. Therefore, focusing on the 76 water tower units of the world, the annual water yield variance was first examined, followed by the contributions of changes in climate, water storage change, and vegetation, as well as their interaction effects on water yield variance; finally, the contribution of water storage change on water yield variance was further decomposed into the effect of changes in groundwater, snow water, and soil water. The results showed that large variability exists in the annual water yield with standard deviations ranging from to 10-368 mm in water towers globally.

Pseudotyped Viruses for Orthohantavirus.

Orthohantaviruses, members of the Orthohantavirus genus of Hantaviridae family of the Bunyavirales order, are enveloped, negative-sense, single-stranded, tripartite RNA viruses. They are emerging zoonotic pathogens carried by small mammals including rodents, moles, shrews, and bats and are the etiologic agents of hemorrhagic fever with renal syndrome (HFRS) and hantavirus cardiopulmonary syndrome (HCPS) among humans. With the characteristics of low biological risk but strong operability, a variety of pseudotyped viruses have been constructed as alternatives to authentic orthohantaviruses to help delineate the roles of host factors in viral entry and other virus-host interactions, to assist in deciphering mechanisms of immune response and correlates of protection, to enhance our understanding of viral antigenic property, to characterize viral entry inhibitors, and to be developed as vaccines.

Integrative proteomics and phosphoproteomics profiling on osteogenic differentiation of periodontal ligament stem cell.

This study aims to elucidate the phosphorylated profile of periodontal ligament stem cells (PDLSCs) osteogenic differentiation, which contributes to the promotion of periodontium regeneration. PDLSCs cultured in the osteogenic induction medium for 14 days were analyzed by proteomics and phosphoproteomics. Potential functions of phosphorylated differentially expressed proteins (DEPs) were annotated and enriched based on Gene Ontology (GO).

PGM3 regulates beta-catenin activity to promote colorectal cancer cell progression.

The hexosamine biosynthetic pathway (HBP) is connected to abnormal N- and O-linked protein glycosylation in cancer, which performs critical roles in tumorigenesis. However, the regulation mechanisms of HBP and its role in colorectal cancer (CRC) progression remain unexplained. This study analyzed the expression level of phosphoglucomutase 3 (PGM3), a key enzyme in HBP, and identified its function in CRC cell lines.

Macrophage-Disguised Manganese Dioxide Nanoparticles for Neuroprotection by Reducing Oxidative Stress and Modulating Inflammatory Microenvironment in Acute Ischemic Stroke.

Reperfusion injury is still a major challenge that impedes neuronal survival in ischemic stroke. However, the current clinical treatments are remained on single pathological process, which are due to lack of comprehensive neuroprotective effects. Herein, a macrophage-disguised honeycomb manganese dioxide (MnO ) nanosphere loaded with fingolimod (FTY) is developed to salvage the ischemic penumbra.

A Versatile Theranostic Platform for Colorectal Cancer Peritoneal Metastases: Real-Time Tumor-Tracking and Photothermal-Enhanced Chemotherapy.

A versatile tumor-targeting stimuli-responsive theranostic platform for peritoneal metastases of colorectal cancer is proposed in this work for tumor tracking and photothermal-enhanced chemotherapy. A quenched photosensitizer ("off" state) is developed and escorted into a tumor-targeting oxaliplatin-embedded micelle. Once reaching the tumor cell, the micelle is clasped to release free oxaliplatin, as well as the "off" photosensitizer, which is further activated ("turned-on") in the tumor reducing microenvironment to provide optical imaging and photothermal effect.

Lysophosphatidic acid mediated PI3K/Akt activation contributed to esophageal squamous cell cancer progression.

Lysophosphatidic acid (LPA) and its G-protein-coupled receptors (Lpar1-Lpar6) mediate a plethora of activities associated with cancer growth and progression. However, there is no systematic study about whether and how LPA promotes esophageal squamous cell carcinoma (ESCC). Here, we show that autotaxin (ATX), a primary LPA-producing enzyme, is highly expressed in ESCC, and overexpressed ATX is associated with the poor outcome of ESCC patients.

Heparin locks with low and high concentration in haemodialysis patients: A systematic review and meta-analysis.

Aim: There is no evidence-based consensus on the optimal concentration for heparin locks; several randomized controlled trials (RCTs) have evaluated the concentration of heparin locks, yet the results remain inconsistent. We aimed to assess heparin locks with low and high concentration in haemodialysis patients.

Methods: We performed a systematic review and meta-analysis of RCTs focusing on the concentration in heparin locks.

Pancreatic cancer-targeting exosomes for enhancing immunotherapy and reprogramming tumor microenvironment.

Immunotherapy has gained increasing focus in treating pancreatic ductal adenocarcinoma (PDAC), since conventional therapies like chemotherapy could not provide satisfactory improvement in overall survival outcome of PDAC patients. However, it is still not the game changing solution due to the unique tumor microenvironment and low cancer immunogenicity of PDAC. Thus, inducing more intratumoral effector immune cells as well as reversing immunosuppression is the core of PDAC treatment.
