Comprehensive analysis of ESCRT transcriptome-associated signatures and identification of the regulatory role of LMO7-AS1 in osteosarcoma.

Osteosarcoma (OS) is a commonly observed malignant tumor in orthopedics that has a very poor prognosis. The endosomal sorting complex required for transport (ESCRT) is important for the development and progression of cancer and may be a significant target for cancer therapy. First, we built a prognostic signature using 7 ESCRT-related genes (ERGs) to predict OS patient prognosis.

Amarogentin suppresses cell proliferation and EMT process through inducing ferroptosis in colorectal cancer.

Background: Colorectal cancer (CRC) is one common tumor with the high death rate, and badly affects the normal lives of CRC patients. Amarogentin (AG) has been found to exhibit regulatory roles and join into the progression of multiple diseases. However, the regulatory impacts and associated molecular mechanisms of AG in CRC progression keep unclear.

Curcumin administration alleviates seminal vesicle damage in type 1 diabetic rats by promoting AQP8 expression through AR activation.

Diabetes is a detriment to male reproductive health, notably through its capacity to diminish secretion from accessory glands such as the seminal vesicles and prostate, which are crucial for reproductive function. Curcumin, a naturally derived polyphenol renowned for its anti-inflammatory and antioxidative attributes, has demonstrated potential in mitigating tissue damage across various organs in diabetic patients. Despite its established benefits, the specific impact of curcumin on seminal vesicle damage in the context of diabetes remains underexplored.

Tunable control of Cas12 activity promotes universal and fast one-pot nucleic acid detection.

The CRISPR-based detection methods have been widely applied, yet they remain limited by the non-universal nature of one-pot diagnostic approaches. Here, we report a universal one-pot fluorescent method for the detection of epidemic pathogens, delivering results within 15-20 min. This method uses heparin sodium to precisely tunes the cis-cleavage capability of Cas12 via interference with the Cas12a-crRNA binding process, thereby generating significant fluorescence due to the accumulation of isothermal amplification products.

Versatile nitrate-respiring heterotrophs are previously concealed contributors to sulfur cycle.

Heterotrophic denitrifiers play crucial roles in global carbon and nitrogen cycling. However, their inability to oxidize sulfide renders them vulnerable to this toxic molecule, which inhibits the key enzymatic reaction responsible for reducing nitrous oxide (NO), thereby raising greenhouse gas emissions. Here, we applied microcosm incubations, community-isotope-corrected DNA stable-isotope probing, and metagenomics to characterize a cohort of heterotrophic denitrifiers in estuarine sediments that thrive by coupling sulfur oxidation with denitrification through chemolithoheterotrophic metabolism.

Efficient Methanol Oxidation Kinetics Enabled by an Ordered Heterocatalyst with Dual Electric Fields.

Induced by a sharp-tip-enhanced electric field, periodical nanoassemblies can regulate the reactant flux on the electrode surface, efficiently optimizing the mass transfer kinetics in electrocatalysis. However, when the nanoscale building blocks in homoassemblies are arranged densely, it results in the overlap and reduction of the local electric field. Herein, we present a comprehensive kinetic heteromodel that simultaneously couples the sharp-tip-enhanced electric field and charge transfer electric field between different building blocks with any arrangement densities.

Arginine-derived carbon dots with antioxidant activity for treating aflatoxin B1-induced liver injury via Nrf2/Keap1 and NLRP3 pathways in mice.

Aflatoxin B1 (AFB1) is a prevalent contaminant in food and feed matrices, known for its hepatotoxic effects. Its metabolic breakdown generates reactive oxygen species (ROS), leading to oxidative stress and subsequent liver damage. Mitigating oxidative stress is, therefore, essential for ameliorating the hepatocellular damage and systemic toxicity caused by AFB1.

Thiol-modified hyaluronic acid and hydroxyl radical-induced oxidation synergistically enhance the gelling capacity of ginkgo seed proteins.

The objective of this work was to investigate the effect of synthetic thiol-modified hyaluronic acid (HASH) on the gelation properties of ginkgo seed protein isolate (GSPI) under non-oxidizing (NOX) or oxidizing (OX) conditions. Under NOX conditions, HASH mediated the disruption of disulfide bonds, leading to a dose-dependent dissociation of GSPI. Conversely, in OX conditions, hydroxyl radical-induced oxidation facilitated the formation of interprotein disulfide bonds.

Proximity-Induced Superconductivity in Ferromagnetic FeGeTe and Josephson Tunneling through a van der Waals Heterojunction.

Synergy between superconductivity and ferromagnetism may offer great opportunities in nondissipative spintronics and topological quantum computing. Yet at the microscopic level, the exchange splitting of the electronic states responsible for ferromagnetism is inherently incompatible with the spin-singlet nature of conventional superconducting Cooper pairs. Here, we exploit the recently discovered van der Waals ferromagnets as enabling platforms with marvelous controllability to unravel the myth between ferromagnetism and superconductivity.
