Osteoarthritis (OA) is the most common joint disease and its pathogenic mechanism remains to be ensured. This study focused on the regulatory relation between B-cell lymphoma 6 (BCL6) and G-protein-coupled receptor 61 (GPR61) underlying IL-1β in OA. Real-time quantitative polymerase chain reaction and western blot were performed for mRNA and protein detection.

Article Synopsis
  • Osteoarthritis (OA) negatively impacts patient mobility, and the role of carbonic anhydrase 12 (CA12) in OA is being investigated, particularly its potential link to inflammation and cell death.
  • Research utilized various methods to analyze gene expression, cell viability, oxidative stress, and cytokine levels, revealing that CA12 is overexpressed in OA-affected cartilage and contributes to inflammation and cell apoptosis.
  • The study suggests that the Wilms' tumor 1-associating protein (WTAP) stabilizes CA12 mRNA via m6A modification, enhancing chondrocyte apoptosis and degradation of cartilage, indicating that targeting CA12 and WTAP could be beneficial for OA treatment.

Background: It has been reported that ferroptosis participates in the pathophysiological mechanism of spinal cord injury (SCI). Our preliminary experiments verified that dendrobium nobile polysaccharide (DNP) improved the behavioral function of SCI rats. Therefore, the purpose of this study was to examine the role of DNP on ferroptosis and its neuroprotective mechanism in SCI rats.

Background: Serum prostate-specific antigen (PSA) is a primary metric for diagnosis and prognosis of prostate cancer (PCa). Exposure to heavy metals, such as lead, cadmium, mercury, and zinc can impact PSA levels in PCa patients. However, it is unclear whether this effect also occurs in men without PCa, which may lead to the overdiagnosis of PCa.

Spin polarization of two-dimensional electron gas (2DEG) at the interface of EuTiO/SrTiO(STO) heterostructures has been theoretical predicted and experimentally observed via x-ray magnetic circular dichroism and polarized x-ray absorption spectroscopy, which, however, is lack of magnetotransport evidence. Here, we report the fabrication of high-quality EuTiO/STO heterostructures by depositing antiferromagnetic insulating EuTiOthin films onto STO substrates. Shubnikov-de Haas oscillation, Hall, and magnetoresistance (MR) measurements show that the interface is not only highly conducting, with electron mobility up to5.
