Article Synopsis
  • - The study examines how calcium (Ca) oscillations in neuron cultures and iPSCs can aid in understanding heart rhythm problems and epilepsy during drug development, focusing on the effects of ischemia and nicotinic acetylcholine receptor (nAChR) modulators.
  • - Ischemia (lack of blood flow) for 1-2 hours increased the frequency of Ca oscillations but decreased their amplitude; the study found that NMDA and AMPA receptor inhibition played a significant role in regulating these oscillations.
  • - The research highlighted that different nAChR subtypes and their positive allosteric modulator drugs influenced Ca oscillations in distinct ways, suggesting potential applications for identifying epilepsy triggers and developing neuroprotect

Phosphatase of regenerating liver (PRL) is an oncogenic protein that promotes tumor progression by directly binding to cyclin M (CNNM) membrane proteins and inhibiting their Mg efflux activity. In this study, we have developed a high-throughput screening system to detect the interactions between PRL and CNNM proteins based on homogenous time-resolved fluorescence resonance energy transfer (HTR-FRET, HTRF). We optimized the tag sequences attached to the recombinant proteins of the CNNM4 CBS domains and PRL3 lacking the carboxyl terminal CAAX motif, and successfully detected the interaction by observing the FRET signal in the mixture of the tagged proteins and fluorophore-conjugated antibodies.

The incorporation of saturated nitrogen-containing heterocycle 1,2,5-oxadiazinane into small molecules represents a compelling avenue in drug discovery due to its unexplored behavior within biological systems and incomplete protocols for synthesis. In this study, we present 1,2,5-oxadiazinane, an innovative heterocyclic bioisostere of piperizin-2-one and novel chemotype of the -schistosomal drug praziquantel (PZQ), which has been the only clinical drug available for three decades. PZQ is associated with significant drawbacks, including poor solubility, a bitter taste, and low metabolic stability.

The one-size-fits-all approach has been the mainstream in medicine, and the well-defined standards support the development of safe and effective therapies for many years. Advancing technologies, however, enabled precision medicine to treat a targeted patient population (e.g.
