Wrinkled Strain‐Enriched High‐Entropy Metallene Enables Cross‐Site Tandem Nitrate‐to‐Ammonia

open access: yesAngewandte Chemie, EarlyView.
A wrinkled 2D PdFeCoNiCuIn high‐entropy metallene overcomes the low atom utilization of high‐entropy alloys. Indium‐induced strain and p‐d hybridization enable a cross‐site tandem pathway for nitrate reduction to ammonia. It achieves 99.3% Faradaic efficiency and an NH3 yield rate of 4.55 mmol h−1 mgcat−1.

RAS oncogenes direct metastasis

open access: yesMolecular & Cellular Oncology, 2017
RAS genes are cardinal driver oncogenes frequently and differentially mutated across bodily tumors. Their tumorigenic potential has been mainly ascribed to autonomous promotion of tumor cell proliferation and survival. However, recent evidence shows that

Spatial and Volumetric Characteristics of Glioblastoma: Associations With Clinical Presentation and Survival

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective We aim to comprehensively analyze how regional tumor and edema characteristics are associated with clinical presentations and survival outcomes in a large cohort of glioblastoma patients. Methods Patients with IDH‐wildtype glioblastoma who received brain MRI from 2010 to 2023 were included.

Neuroblastoma RAS Viral Oncogene Homolog (NRAS) Is a Novel Prognostic Marker and Contributes to Sorafenib Resistance in Hepatocellular Carcinoma

open access: yesNeoplasia: An International Journal for Oncology Research, 2019
Inhibition of the RAS-RAF-ERK-pathway using sorafenib as a first-line and regorafenib as a second-line treatment approach is the only effective therapeutic strategy for advanced hepatocellular carcinoma (HCC).

Extracellular Vesicle‐Transferred ATP‐Citrate Lyase Induces Monocyte Differentiation Toward Tumor‐Associated Macrophages and Fuels Hepatocellular Carcinoma Progression

open access: yesAdvanced Science, EarlyView.
Hepatocellular carcinoma (HCC)‐derived extracellular vesicles (EVs) enrich the metabolic enzyme ATP‐citrate lyase (ACLY). EV‐transferred ACLY enhances palmitate biosynthesis, increases the S‐palmitoylation and stability of multiple immune checkpoint proteins, augments the cellular immunosuppressive activity, and ultimately accelerates the malignant ...

Elevated NRAS expression during DCIS is a potential driver for progression to basal-like properties and local invasiveness

open access: yesBreast Cancer Research, 2022
Background Ductal carcinoma in situ (DCIS) is the most common type of in situ premalignant breast cancers. What drives DCIS to invasive breast cancer is unclear. Basal-like invasive breast cancers are aggressive.

Identification of NRAS Downstream Genes with CRISPR Activation Screening

open access: yesBiology, 2022
Mutations in NRAS constitutively activate cell proliferation signaling in malignant neoplasms, such as leukemia and melanoma, and the clarification of comprehensive downstream genes of NRAS might lead to the control of cell-proliferative signals of NRAS ...

Endogenous Engineering Reprograms Extracellular Vesicles for Enhanced Therapeutic Function

open access: yesAdvanced Science, EarlyView.
This review explains how Extracellular vesicles‐producing cells can be endogenously engineered to load therapeutic proteins and nucleic acids. We summarize physiological and genetic strategies that harness native sorting pathways for selective cargo loading.
