Auranofin (AF), a gold (I)-containing phosphine compound, is being investigated for oncological application as a repurposed drug. We show here that 4~5 µM AF induces paraptosis, a non-apoptotic cell death mode characterized by dilation of the endoplasmic reticulum (ER) and mitochondria, in breast cancer cells. Although the covalent inhibition of thioredoxin reductase (TrxR), an enzyme that critically controls intracellular redox homeostasis, is considered the primary mechanism of AF's anticancer activity, knockdown of TrxR1 did not induce paraptosis.

Article Synopsis
  • Semisulcospira gottschei is a freshwater and marine species native to Korea and China, but its genetic diversity has not been deeply studied previously.
  • This research sequenced mitochondrial DNA and analyzed microsatellite markers to explore the genetic structures of S. gottschei populations, finding 43 distinct haplotypes that indicated no gene flow between the Korean and Chinese groups.
  • The study revealed significant genetic diversity within populations, forming two distinct clusters that could aid in managing and restoring these populations, helping to differentiate their origins for conservation efforts.

Article Synopsis
  • Pufferfish are important to the economy as edible fish, but misidentification can result in poisoning, making accurate species identification vital.
  • This study utilized the mtDNA COI gene to create specific primers that can quickly identify six of the 21 pufferfish species sold in Korea via a multiplex PCR method.
  • The method proved effective, allowing for the identification of each species within six hours, thus helping to prevent mislabeled fish, protect consumers, and reduce poisoning risks.

A highly accurate quantitative method, based on the new technique, droplet digital PCR (ddPCR), was applied to determine the content of Alaska pollock (Gadus chalcogrammus) in seafood products. Using this method, we found a linear relationship among raw sample weight, DNA concentration and DNA copy number. We also established a formula to calculate the raw sample weight, based on the number of DNA copies.

The antiviral activity of an extract mixture from Celosia cristata and Raphanus sativus was tested against viral hemorrhagic septicemia virus (VHSV). Pretreatment of EPC cells with this extract up to 72 h before VHSV infection markedly reduced the virus titer, but it had no effect when added after virus inoculation. In olive flounder that received 5 µg of extract per fish, Mx expression peaked at 48 h after treatment.

SPIN90 is an F-actin binding protein thought to play important roles in regulating cytoskeletal dynamics. It is known that SPIN90 is expressed during the early stages of neuronal development, but details of its localization and function in growth cones have not been fully investigated. Our immunocytochemical data show that SPIN90 is enriched throughout growth cones and neuronal shafts in young hippocampal neurons.

Achondroplasia is a congenital disorder resulting from a specific disturbance in endochondral bone formation. The ophthalmic features reportedly associated with achondroplasia are telecanthus, exotropia, inferior oblique overaction, angle anomalies and cone-rod dystrophy. This is first report of chorioretinal coloboma in achondroplasia.

To test the applicability of Caenorhabditis elegans mutant for toxicity screening, the sensitivity of cadmium (Cd) in C. elegans was investigated on 14 mutant strains using median lethal concentration (LC50) tests, with further analysis on growth and reproduction conducted on five selected strains. The 24h LC50 of Cd observed on the wildtype and mutant strains of C.
