Targeting lipid metabolism via nanomedicine: A prospective strategy for cancer therapy.

Lipid metabolism has been increasingly recognized to play an influencing role in tumor initiation, progression, metastasis, and therapeutic drug resistance. Targeting lipid metabolic reprogramming represents a promising therapeutic strategy. Despite their structural complexity and poor targeting efficacy, lipid-metabolizing drugs, either used alone or in combination with chemotherapeutic agents, have been employed in clinical practice.

LIPUS activated piezoelectric pPLLA/SrSiO composite scaffold promotes osteochondral regeneration through P2RX1 mediated Ca signaling pathway.

Addressing the concurrent repair of cartilage and subchondral bone presents a significant challenge yet is crucial for the effective treatment of severe joint injuries. This study introduces a novel biodegradable composite scaffold, integrating piezoelectric poly-l-lactic acid (pPLLA) with strontium-enriched silicate bioceramic (SrSiO). This innovative scaffold continually releases bioactive Sr and SiO ions while generating an electrical charge under low-intensity pulsed ultrasound (LIPUS) stimulation, a clinically recognized method.

Comparative analysis of the performance, egg quality and ovarian immune function of fast and slow feather strains in tianfu green shell laying hens at various stages of egg production.

This objective of this experiment was to compare and evaluate the performance, egg quality, and immune function of Tianfu green shell laying hens with varying feather growth rates, in order to provide a reference for their rational utilization. A total of 120 one-day-old healthy Tianfu green shell laying hens were classified into the early-feathering (EF) and late-feathering (LF) groups through phenotypic identification of feather length and qPCR molecular identification. Each group was subdivided into four replicates, with 30 chickens in each replicate.

IGF2BP3 curbed by miR-15c-3p restores disrupted lipid storage and progesterone secretion in chicken granulosa cells under oxidative stress through AKT-Raf1-ERK1/2 signaling pathway.

For commercial laying hens, the continuous high-intensity ovulation process leads to a significant accumulation of reactive oxygen species (ROS) in the granulosa cells, inducing oxidative stress, which accelerates ovarian aging and shortens the peak laying period. The molecular mechanisms underlying this process remain poorly understood. Therefore, we modeled the processes of oxidative stress and antioxidant in chicken granulosa cells.

Thioether functionalized degradable poly(amino acids) and its calcium sulfate/calcium hydrogen phosphate composites: Reducing oxidative stress and promoting osteogenesis.

The imbalance of redox homeostasis, especially the abnormal levels of reactive oxygen species (ROS), is a key obstacle in the bone repair process. Therefore, developing materials capable of scavenging ROS and modulating the microenvironment of bone defects is crucial for promoting bone repair. In this study, to endow poly(amino acids) (PAA) and its composites with anti-oxidative stress properties and enhanced osteogenic differentiation, we designed and prepared a calcium sulfate/calcium hydrogen phosphate/poly(amino acids) (PCDM) composite material with a thioether structure (-S-) in the molecular chain of PAA matrix through situ polymerization and physical blending method.

Cysteine-Specific F and NIR Dual Labeling of Peptides via Vinyltetrazine Bioorthogonal Conjugation for Molecular Imaging.

Radiolabeled peptides are vital for positron emission tomography (PET) imaging, yet the F-labeling peptides remain challenging due to harsh conditions and time-consuming premodification requirements. Herein, we developed a novel vinyltetrazine-mediated bioorthogonal approach for highly efficient F-radiolabeling of a native peptide under mild conditions. This approach enabled radiosynthesis of various tumor-targeting PET tracers, including targeting the neurofibromin receptor (), the integrin αβ (), and the platelet-derived growth factor receptor β (), with a radiochemical yield exceeding 90%.

Deciphering the Power of Resveratrol in Mitophagy: From Molecular Mechanisms to Therapeutic Applications.

Resveratrol (RES), a natural polyphenolic compound, has garnered significant attention for its therapeutic potential in various pathological conditions. This review explores how RES modulates mitophagy-the selective autophagic degradation of mitochondria essential for maintaining cellular homeostasis. RES promotes the initiation and execution of mitophagy by enhancing PINK1/Parkin-mediated mitochondrial clearance, reducing reactive oxygen species production, and mitigating apoptosis, thereby preserving mitochondrial integrity.
