CHAC1 in urological tumors: contextual dualism and therapeutic implications.

CHAC1, a glutathione-degrading enzyme, governs context-dependent pathophysiological processes in urological malignancies through modulation of endoplasmic reticulum stress and ferroptotic pathways. In clear cell renal cell carcinoma (ccRCC), CHAC1 exhibits stage-specific functional duality: downregulation in early-stage tumors correlates with adverse prognosis (suggesting tumor-suppressive activity), whereas elevated expression in advanced ccRCC (G3-G4/Stage III-IV) associates with increased mortality (indicating adaptive pro-survival adaptation). For prostate cancer, CHAC1 potentiates docetaxel cytotoxicity via coordinated induction of endoplasmic reticulum stress and ferroptosis, yet its suppression by cancer-associated fibroblast-derived exosomal miR-432-5p establishes therapy-reinforced chemoresistance.

Anti-Müllerian hormone signalling sustains circadian homeostasis in zebrafish.

Circadian clocks temporally orchestrate the behavioural and physiological rhythms. The core molecules establishing the circadian clock are clear; however, the critical signalling pathways that cause or favour the homeostasis are poorly understood. Here, we report that anti-Müllerian hormone (Amh)-mediated signalling plays an important role in sustaining circadian homeostasis in zebrafish.

Chr23-miR-200s and Dmrt1 Control Sexually Dimorphic Trade-Off Between Reproduction and Growth in Zebrafish.

In animals, a trade-off exists between reproduction and growth, which are the most fundamental traits. Males and females exhibit profound differences in reproduction and growth in fish species. However, the precise molecular mechanism governing this phenomenon is still not clear.

PET-MR Guided, Pre-targeted delivery to HER2(+) Breast Cancer Model.

Purpose: HER2(+) metastatic breast cancer (mBC) is one of the most aggressive and lethal cancer types among females. While initially effective, targeted therapeutic approaches with trastuzumab and pertuzumab antibodies and antibody-drug conjugates (ADC) lack long-term efficacy against HER2(+) mBC and can cause severe systemic toxicity due to off-target effects. Therefore, the development of novel targeted delivery platforms that minimize toxicity and increase therapeutic efficacy is critical to the treatment of HER2(+) breast cancer (BC).

Synergy of 5-aminolevulinate supplement and CX3CR1 suppression promotes liver regeneration via elevated IGF-1 signaling.

Inadequate remnant volume and regenerative ability of the liver pose life-threatening risks to patients after partial liver transplantation (PLT) or partial hepatectomy (PHx), while few clinical treatments focus on safely accelerating regeneration. Recently, we discovered that supplementing 5-aminolevulinate (5-ALA) improves liver cold adaptation and functional recovery, leading us to uncover a correlation between 5-ALA metabolic activities and post-PLT recovery. In a mouse 2/3 PHx model, 5-ALA supplements enhanced liver regeneration, promoting infiltration and polarization of anti-inflammatory macrophages via P53 signaling.

A Skin-Inspired Multifunctional Conductive Hydrogel with High Stretchable, Adhesive, Healable, and Decomposable Properties for Highly Sensitive Dual-Sensing of Temperature and Strain.

Developing smart hydrogels with excellent physicochemical properties and multi-sensing capabilities for various simulation of human skin's functions still remains a great challenge. Here, based on simple and convenient one-step covalent cross-linking method enhanced by dynamic RS-Ag interactions, a skin-inspired multifunctional conductive hydrogel with desirable physicochemical properties (including high stretchability, self-adhesion, self-healing, decomposition and removability) is developed for highly sensitive dual-sensing of temperature and strain. Benefiting from the synergistic action of multiple hydrogen bonds, RS-Ag bonds and S-S bonds, the gel exhibited a novel thermosensitive mechanism.

Ultrasmall Superparamagnetic Iron Oxide Nanoparticles as Nanocarriers for Magnetic Resonance Imaging: Development and Characterization.

Ultrasmall superparamagnetic iron oxide nanoparticles (uSPIOs) are attractive platforms for the development of smart contrast agents for magnetic resonance imaging (MRI). Oleic acid-capped uSPIOs are commercially available yet hydrophobic, hindering applications. A hydrophilic ligand with high affinity toward uSPIO surfaces can render uSPIOs water-soluble, biocompatible, and highly stable under physiological conditions.

VEGF Overexpression Significantly Increases Nanoparticle-Mediated siRNA Delivery and Target-Gene Downregulation.

The availability of nanoparticles (NPs) to deliver small interfering RNA (siRNA) has significantly expanded the specificity and range of 'druggable' targets for precision medicine in cancer. This is especially important for cancers such as triple negative breast cancer (TNBC) for which there are no targeted treatments. Our purpose here was to understand the role of tumor vasculature and vascular endothelial growth factor (VEGF) overexpression in a TNBC xenograft in improving the delivery and function of siRNA NPs using in vivo as well as ex vivo imaging.

Genome-wide association study reveals the genetic basis of growth trait in yellow catfish with sexual size dimorphism.

Sexual size dimorphism has been widely observed in a large number of animals including fish species. Genome-wide association study (GWAS) is a powerful tool to dissect the genetic basis of complex traits, whereas the sex-differences in the genomics of animal complex traits have been ignored in the GWAS analysis. Yellow catfish (Pelteobagrus fulvidraco) is an important aquaculture fish in China with significant sexual size dimorphism.

Dual-Modality PET-SPECT Image-Guided Pretargeting Delivery in HER2(+) Breast Cancer Models.

Pretargeted drug delivery has been explored for decades as a promising approach in cancer therapy. An image-guided pretargeting strategy significantly enhances the intrinsic advantages of this approach since imaging the pretargeting step can be used for diagnostic purposes, while imaging of the drug delivery step can be utilized to evaluate drug distribution and assess therapeutic response. A trastuzumab (Tz)-based HER2 pretargeting component (Tz-TCO-[Zr-DFO]) was developed by conjugating with -cyclooctene (TCO) bioorthogonal click chemistry functional groups and deferoxamine (DFO) to enable radiolabeling with a Zr PET tracer.

Identifying difference in primordial germ cells between XX female and XY male yellow catfish embryos.

Primordial germ cells (PGCs) are singled out from somatic cells very early during embryogenesis, then they migrate towards the genital ridge and differentiate into gametes through oogenesis or spermatogenesis. Labeling PGCs with Localized RNAexpression (LRE) technique by fluorescent proteins has been widely applied among teleost species to study the germ cell development and gonad differentiation. In this study, we first cloned and characterized the 3' untranslated regions (3'UTRs) of nanos homolog 1-like (nos1l), dead end (dnd), and vasa in yellow catfish (Pelteobagrus fulvidraco), and then synthesized the GFP-nos1l/dnd/vasa 3'UTR mRNAs.

The microRNA-200 cluster on chromosome 23 is required for oocyte maturation and ovulation in zebrafish†.

The reproductive process is usually controlled by the hypothalamic-pituitary-gonad axis in vertebrates, while Kiss/gonadotropin-releasing hormone (GnRH) system in the hypothalamus is required for mammalian reproduction but dispensable for fish reproduction. The regulation of follicle stimulating hormone/luteinizing hormone (LH) expression in fish species is still unknown. Here, we identified miR-200s on chromosome 23 (chr23-miR-200s) as important regulators for female zebrafish reproduction.

Igf2bp1 is required for hepatic outgrowth during early liver development in zebrafish.

IGF2BPs, a subclass of RNA-binding proteins, regulate cellular differentiation, proliferation and migration during multiple organs development, but their functions in liver development still remain unclear. Here, in this study, whole-mount in situ hybridization showed that igf2bp1 was constantly and stably expressed at early stages of embryo development in zebrafish. Both the morpholino-induced knockdown and CRISPR/Cas9-mediated knockout of igf2bp1 led to a reduced-size liver phenotype.
