PCBP2-dependent secretion of miRNAs via extracellular vesicles contributes to the EGFR-driven angiogenesis.

The EGFR-driven angiogenesis is crucial in solid tumors, particularly through the delivery of biomolecules via extracellular vesicles (EVs), but the mechanism by which EGFR regulates EV cargo is still unclear. First, cell co-culture and murine tumor models were employed to examine the impact of EGFR overexpression on the pro-angiogenic properties of small EVs (sEVs) derived from oral squamous cell carcinoma (OSCC). Small RNA sequencing was then used to compare the miRNA profiles of OSCC-sEVs with and without EGFR overexpression, followed by functional enrichment and motif analyses of the differentially expressed miRNAs.

Metabolic Engineering of BL21(DE3) for 2'-Fucosyllactose Synthesis in a Higher Productivity.

2'-Fucosyllactose (2'-FL) is the most abundant human milk oligosaccharides (HMOs). 2'-FL exhibits great benefits for infant health, such as preventing infantile diarrhea and promoting the growth of intestinal probiotics. The microbial cell factory technique has shown promise for the massive production of 2'-FL.

Nedd4 family interacting protein 1 directly regulates the NF-κB signaling pathway without promoting the ubiquitination of Tak1 in Nile tilapia.

Mammalian Nedd4 family interacting protein 1 (Ndfip1) serves as an activator of the E3 ubiquitin ligase, promoting ubiquitination and limiting the production of pro-inflammatory cytokines. However, the functional role of teleost Ndfip1 is not completely understood. In the current study, an Ndfip1 gene designated as OnNdfip1 was characterized in Nile tilapia.

Modulation of RuO Nanocrystals with Facile Annealing Method for Enhancing the Electrocatalytic Activity on Overall Water Splitting in Acid Solution.

RuO-based materials are considered an important kind of electrocatalysts on oxygen evolution reaction and water electrolysis, but the reported discrepancies of activities exist among RuO electrocatalysts prepared via different processes. Herein, a highly efficient RuO catalysts via a facile hydrolysis-annealing approach is reported for water electrolysis. The RuO catalyst dealt with at 200 °C (RuO-200) performs the highest activities on both oxygen evolution reaction (OER) and hydrogen evolution reaction (HER) in acid with overpotentials of 200 mV for OER and 66 mV for HER to reach a current density of 100 mA cm as well as stable operation for100 h.

Inhibition of IFITM3 in cerebrovascular endothelium alleviates Alzheimer's-related phenotypes.

Introduction: Interferon-induced transmembrane protein 3 (IFITM3) modulates γ-secretase in Alzheimer's Disease (AD). Although IFITM3 knockout reduces amyloid β protein (Aβ) production, its cell-specific effect on AD remains unclear.

Methods: Single nucleus RNA sequencing (snRNA-seq) was used to assess IFITM3 expression.
