Summary: Alkaline phosphatase (ALP) is a widely present and important biomarker in the human body. Researchers synthesized a core-shell metal-organic framework sensor that can be used for sensitive and accurate ALP detection. By self-triggered control of phosphate ions (Pi), the sensor avoids the potential inaccuracy caused by using ascorbic acid (AA) as the reducing component. The developed strategy has shown linear response to ALP concentrations ranging from 0.1 to 150 mU/mL with a detection limit of 0.03 mU/mL.

Summary: Optimization of mass transfer within nanoporous gold-modified gold electrode greatly influences the voltammetric profile of ascorbic acid oxidation reaction. The surface porosity of nanoporous gold depends on electrodeposition parameters and affects the mass transport behavior of ascorbic acid. The combination of diffusion and thin layer EC1 mechanism determines the predominance of mass transport and can be controlled by electrodeposition parameters and substrate size.

Summary: This article presents an electrochemical technique that uses an electroactive tracer species to probe the rate-limiting factors of redox reactions at an electrode surface. A theoretical model is developed for the transient response in step 2, considering diffusion-limited and desorption-limited recovery of the electrode potential. The mathematical modeling shows that in a desorption-limited system, the electrode potential drifts to open circuit slowly compared to a diffusion-limited system. This technique can be used to study adsorption-desorption processes during electrochemistry.

Summary: Vitamin C is known to regulate hematopoietic stem cells and leukemogenesis. However, glucose transporter 3 (GLUT3) deficiency in acute myeloid leukemia (AML) blocks the uptake of vitamin C and diminishes its clinical benefits. This study aimed to investigate the therapeutic potential of restoring GLUT3 in AML. Restoring GLUT3 expression in AML cells enhanced TET2 activity and improved the anti-leukemic effect of vitamin C treatments. Pharmacological salvage of GLUT3 deficiency has the potential to improve the effectiveness of vitamin C in AML treatment.

Summary: One of the major challenges in measuring dopamine (DA) using electro-chemical methods in living organisms is to achieve selectivity in the presence of interfering substances like ascorbic acid (AA) and uric acid (UA). Researchers have used complicated multimaterial structures and ill-defined pretreatments to enhance selectivity. However, the lack of control over the electrode structures has made it difficult to establish a relationship between selectivity and structure. Carbon nanofiber (CNF) electrodes have shown promise in neurobiological applications due to their easily customizable structure. In this study, the sensitivity and selectivity of CNF electrodes towards DA were controlled by adjusting the lengths of the CNF during the fabrication process while maintaining similar surface chemistries. It was found that increasing the fiber length enhanced the sensitivity towards DA while also causing a shift in the oxidation peaks of AA and DA, leading to excellent selectivity.

Summary: Nicotinic acid adenine dinucleotide phosphate (NAADP) is a second messenger that releases Ca2+ from endosomes and lysosomes by activating two-pore channels (TPCs). Two different NAADP-binding proteins (NAADP-BPs), JPT2 and LSM12, have recently been identified, bridging the gap between NAADP generation and NAADP activation of TPCs. The discovery of these NAADP-BPs will facilitate future studies on the molecular mechanism of NAADP action.

Summary: The anthelmintic drug praziquantel (PZQ) causes contraction of parasitic schistosomes and blood vessels. PZQ's action on the vasculature is mediated by the activation of host serotonergic 5-HT2B receptors. The molecular basis for PZQ interaction with these receptors and their location in the vessel wall have not been experimentally defined.

Summary: The drug praziquantel (PZQ) is the key clinical therapy for treating schistosomiasis and other infections caused by parasitic flatworms. A recent study identified a target for PZQ in parasitic flatworms, but little is known about its properties in other flatworms. This study found that the PZQ target is present in all parasitic flatworms and showed different sensitivities to PZQ among different flatworms. The study also identified variations in the binding pocket of the PZQ target, which explains why PZQ is effective against specific infections.

Summary: The anthelmintic drug praziquantel is highly effective against parasitic flatworms, but its target has remained undefined. This study demonstrates that praziquantel analogs show different activities against different parasites, which is reflected by unique structure-activity relationships at the TRPMPZQ channels found in these organisms. These findings provide further support for TRPMPZQ as the therapeutically relevant target of praziquantel.

Summary: This study found that low expression of TP53INP2 is associated with poor survival in colorectal cancer (CRC) patients. As the malignancy of CRC progresses, TP53INP2 expression gradually decreases. Knockdown of TP53INP2 promotes CRC cell proliferation and tumor growth. Mechanistically, TP53INP2 deficiency decreases phosphorylation of beta-catenin, leading to increased accumulation and enhanced nuclear translocation and transcriptional activity. Additionally, TP53INP2 sequesters TIM50, inhibiting its activation of beta-catenin. In conclusion, downregulation of TP53INP2 promotes CRC progression by activating beta-catenin.
