Summary: In this study, the role of C17orf53 in hepatocellular carcinoma (HCC) was analyzed using public datasets. The findings suggest that C17orf53 is highly expressed and predicts poor survival in HCC patients. It also correlates positively with the abundance of B cells, macrophages, and dendritic cells. Functional analysis revealed that C17orf53 is involved in cell cycle, DNA replication, and Fanconi anemia pathways. Knockdown of C17orf53 inhibited cell proliferation and decreased the expression of MCM8, cyclin D1, and PCNA. Overall, C17orf53 is a novel prognostic signature for HCC.

Summary: Fruit malformation is a widespread issue in fruit production, causing significant economic losses. Although farmers have long observed the association between chilling temperature before blooming and malformed fruits, the molecular mechanism behind this phenomenon remains unclear. In this study, we investigated how tomato fruit development responded to cold stress and found that short-term cold stress led to increased callose accumulation in both shoot apical and floral meristems. This caused symplastic isolation and altered intercellular movement of WUS, resulting in expanded stem cell population and malformed fruits. Our findings suggest that the callose dynamics during short-term cold stress involve the interplay of abscisic acid and gibberellin, similar to bud dormancy mechanisms. This study provides new insights into the regulation of fruit malformation under cold stress.

Summary: Magnetically insulated coaxial diodes are commonly used in high power microwave devices for generating intense annular electron beams. This study conducted electrical and optical measurements on a long-pulse magnetically insulated coaxial diode to observe the emission characteristics and plasma properties. The impact of cathode material, blade angle, diode voltage, and guiding magnetic field on the emission characteristics and plasma properties of six types of annular cathodes was investigated. The metal-dielectric cathode showed excellent emission characteristics and plasma properties, achieving impressive diode performance. Additionally, high voltage and small blade angle were found to enhance the emission capability and uniformity, while a strong magnetic field or large diode voltage reduced the axial and radial expansion velocities.

Summary: Bortezomib (BTZ) is an effective drug for multiple myeloma treatment, but it often leads to BTZ-induced peripheral neuropathy (BIPN). In this study, it was found that BTZ caused demyelination in sciatic nerves, leading to mechanical hyperalgesia and impaired nerve conduction. The mechanism was identified as the dysfunction of lysosomes and autophagy blockage in Schwann cells. However, the use of the lysosomal activator Torin1 reversed the autophagy blockage and improved the BIPN pathology.

Summary: This study found that MAOB was highly overexpressed in the spinal cord and DRG tissues of PIPN mice, rather than MAOA, and Khellin as a selective MAOB inhibitor could improve PIPN-like pathology. Moreover, Khellin promoted neurite outgrowth, alleviated apoptosis, and improved mitochondrial dysfunction of DRG neurons by targeting MAOB, while inhibiting spinal astrocytes activation and suppressing neuroinflammation through the MAOB/NF-kappa B/NLRP3/ASC/Caspase1/IL-1 beta pathway. These findings provide potential therapeutic approaches for treating the side effects of PTX-induced neuropathy using selective MAOB inhibitors.

Summary: This study investigated the influence of binding strength (BS) of extracellular organic substances (EOS) on organic matter (OM) recovery from sewage sludge. The results revealed the effects of multivalent metals, floc structures, and rheological properties on the release of EOS. The power-law distribution of BS was found to determine the state of organic molecules, stability of floc structures, and rheological properties. Hierarchical cluster analysis identified three levels of BS in EOS, indicating three stages of OM release or recovery from sludge. This study provides a theoretical basis for developing methods for OM release and recovery from sludge.
