Orphan nuclear receptor NR2E3 is a new molecular vulnerability in solid tumors by activating p53.

The orphan nuclear receptor NR2E3 has emerged as a potential tumor suppressor, yet its precise mechanisms in tumorigenesis require further investigation. Here, we demonstrate that the full-length protein isoform of NR2E3 instead of its short isoform activates wild-type p53 and is capable of rescuing certain p53 mutations in various cancer cell lines. Importantly, we observe a higher frequency of NR2E3 mutations in three solid tumors compared to the reference population, highlighting its potential significance in tumorigenesis.

Years of life lost attributable to air pollution, a health risk-based air quality index approach in Ningbo, China.

Air pollution remains a significant threat to human health and economic development. Most previous studies have examined the health effects of individual pollutants, which often overlook the combined impacts of multiple pollutants. The traditional composite indicator air quality index (AQI) only focuses on the major pollutants, whereas the health risk-based air quality index (HAQI) could offer a more comprehensive evaluation of the health effects of various pollutants on populations.

Copper-catalysed radical cascade reaction of -(2-oxo-2-phenylethyl) substituted 2-pyridones with styrene to access 1,6-carboannulated 2-pyridone scaffolds.

Herein, we present that treating -(2-oxo-2-phenylethyl) substituted 2-pyridones with styrenes in DMSO/HO at 120 °C affords 1,6-carboannulated 2-pyridone scaffolds with up to 79% yield. This protocol provides a simple and efficient method for obtaining complicated bicyclic 2-pyridones through a radical cascade reaction. Additionally, we have successfully synthesized 27 target compounds, which confirms the practicality and wide applicability of the proposed reaction.

Long non-coding RNAs (lncRNAs) have emerged as important regulators of cell proliferation and differentiation. Nuclear paraspeckle assembly transcript 1 (NEAT1) has been implicated in various cellular processes, but its role in granulosa cell function remains unclear.

Nematode controlling effects and safety tests of Duddingtonia flagrans biological preparation in sheep.

Duddingtonia flagrans is a nematode-trapping fungus that is widely used to control parasitic nematodes in livestock. After oral ingestion and passage through the digestive tract of animals, this microorganism captures nematodes in feces.

Two-Dimensional Phototransistors with van der Waals Superstructure Contacts for High-Performance Photosensing.

Semiconducting transition metal dichalcogenides (TMDs) possess exceptional photoelectronic properties, rendering them excellent channel materials for phototransistors and holding great promise for future optoelectronics. However, the attainment of high-performance photodetection has been impeded by challenges pertaining to electrical contact. To surmount this obstacle, we introduce a phototransistor architecture, in which the WS channel is connected with an alternating WS-WSe strip superstructure, strategically positioned alongside the source and drain contact regions.

A Review of the Therapeutic Potential of Ginseng and Its Bioactive Components in Nonalcoholic Fatty Liver Disease.

Non-alcoholic fatty liver disease (NAFLD) is the major cause of chronic liver disease worldwide, with no universally recognized effective treatments currently available. In recent years, ginseng and its principal active components, such as ginsenosides, have shown potential protective effects in the treatment of these liver diseases. In NAFLD, studies have demonstrated that ginseng can improve hepatic lipid metabolism, reduce inflammatory responses, and inhibit oxidative stress and fibrosis, thereby attenuating the progression of NAFLD.

Maintenance of neuronal TDP-43 expression requires axonal lysosome transport.

TDP-43 mislocalization and pathology occurs across a range of neurodegenerative diseases, but the pathways that modulate TDP-43 in neurons are not well understood. We generated a Halo-TDP-43 knock-in iPSC line and performed a genome-wide CRISPR interference FACS-based screen to identify modifiers of TDP-43 levels in neurons. A meta-analysis of our screen and publicly available screens identified both specific hits and pathways present across multiple screens, the latter likely responsible for generic protein level maintenance.
