Exploring ABI5 regulation: Post-translational control and cofactor interactions in ABA signaling.

Abscisic acid insensitive 5 (ABI5) is a pivotal transcription factor in abscisic acid (ABA) signaling, playing an essential role in plant growth and responses to abiotic stress. This key regulator is subject to multifaceted regulation, especially on post-translational mechanisms. Recent research has shed light on the post-translational regulation of ABI5, encompassing both post-translational modifications (PTMs) and the modulation of its transcriptional activity.

Squamocin Suppresses Tumor Growth through Triggering an Endoplasmic Reticulum Stress-Associated Degradation of EZH2/MYC Axis.

Despite substantial advances in the antitumor effects of annonaceous acetogenins (ACGs), the absence of a defined biological action mechanism remains a major barrier to their clinical application. Here, it is found that squamocin effectively depletes both EZH2 and MYC in multiple cancer cell lines, including head and neck squamous cell carcinoma, and gastric and colorectal cancer, demonstrating potent efficacy in suppressing these in vivo tumor models. Through the combination of surface plasmon resonance (SPR), differential scanning fluorimetry (DSF), and cellular thermal shift assay (CETSA), heat shock protein 90α (HSP90α) is identified as the direct binding target of squamocin.

Isoliensinine suppresses chondrocytes pyroptosis against osteoarthritis via the MAPK/NF-κB signaling pathway.

Background: Isoliensinine is an active compound derived from Nelumbo nucifera which has long been used for its anti-inflammatory properties. However, the mechanism of Isoliensinine in the treatment of osteoarthritis is poorly known.

Purpose: The present study aims to investigate whether Isoliensinine could alleviate osteoarthritis by regulating MAPK/NF-κB signaling pathway-mediated pyroptosis.

Activation, but not inactivation, of the medial or lateral orbitofrontal cortex impaired context-specific fear encoding.

In laboratories, classical fear conditioning and extinction procedures are commonly used to study the behavioral and neural mechanisms underlying fear regulation. Contextual fear conditioning involves the association of an aversive event with the environment where it occurs, which engages the hippocampus and its interactions with the amygdala. The orbitofrontal cortex (OFC), divided into the lateral OFC (lOFC) and medial OFC (mOFC) subregions, plays a crucial role in integrating contextual information from the hippocampus and modulating behavioral responses based on the anticipated outcomes of the context.

Methods: The national survey was conducted from November 7 to November 28, 2022.

Finite element study on the micromechanics of cement-augmented proximal femoral nail anti-rotation (PFNA) for intertrochanteric fracture treatment.

Blade cut-out is a common complication when using proximal femoral nail anti-rotation (PFNA) for the treatment of intertrochanteric fractures. Although cement augmentation has been introduced to overcome the cut-out effect, the micromechanics of this approach remain to be clarified. While previous studies have developed finite element (FE) models based on lab-prepared or cadaveric samples to study the cement-trabeculae interface, their demanding nature and inherent disadvantages limit their application.

Mitochondria protective and anti-apoptotic effects of peripheral benzodiazepine receptor and its ligands on the treatment of asthma in vitro and vivo.

Background: Asthma is a prevalent respiratory inflammatory disease. Abnormal apoptosis of bronchial epithelial cells is one of the major factors in the progression of asthma.
