Summary: This study reports a facile method to synthesize corn-like Mg-calcite mesocrystals using only Ca2+ and Mg2+ from pure ACC. The resulting mesocrystals consist of many nanocubes with common crystallographic orientation, displaying excellent single crystal features. In the crystallization process, ACC nanospheres rapidly agglomerate into Mg-calcite corn-like mesocrystals through oriented attachment in a certain direction, shedding new light on the role of seawater in the formation of biological Mg-calcite.

Summary: Ca- and Mg-based batteries are more sustainable alternatives to Li-ion batteries, but suffer from poor mass transport of cations. Organic positive electrodes, although most sustainable and potentially low-cost, currently have the best electrochemical performances in Ca and Mg cells but suffer from low capacity retention upon cycling, the origin of which is not yet fully understood.

Summary: Alkali-earth metal ions, specifically calcium and magnesium, bind to DNA differently, with calcium ions leading to compact DNA structures and magnesium ions having a propensity to appear near the DNA backbone due to steric effects. Calcium ions exhibit a dynamic solvent shell and strong coordination with free oxygen atoms of phosphate, promoting the formation of A-type DNA structures.

Summary: The study investigated the interaction of Sr2+ with Ca2+ binding sites of a canonical EF-hand protein, alpha-parvalbumin, suggesting that Sr2+ and Ca2+ bind to CD/EF sites of alpha-PA with sequential binding processes. Despite lower affinity to Sr2+, alpha-PA competes with Ca2+ for the same EF-hands, inducing similar structural rearrangements. The presence of a secondary Sr2+ binding site(s) may contribute to Sr2+ impact on the functional activity of proteins.

Summary: Calcium signaling plays a crucial role in the regulation of the obligate intracellular parasite Toxoplasma gondii, and a novel EF-hand domain-containing protein, TgEFP1, has been identified in this calcium homeostasis network, localizing to the PLV/ELC and PV. Knockout of TgEFP1 results in faster parasite propagation, hypersensitivity to calcium ionophore-induced egress, and premature natural egress.

Summary: The Mg/Ca ratio in echinoderm skeletons is influenced by seawater chemistry, indicating that fossil echinoderms may provide a record of paleoseawater Mg2+/Ca2+. While sea stars were not significantly stressed by decreased seawater Mg2+/Ca2+, brittle stars were affected in growth and mortality. Reconstruction of paleoseawater Mg2+/Ca2+ from fossil echinoderms is limited by variations in Mg partition coefficients among different species.

Summary: Neuronal K(V)7 channels are highly sensitive to reactive oxygen species, and the S2S3 linker of the voltage sensor plays a crucial role in redox modulation of the channels. Recent structural studies have revealed interactions between this linker and the Ca2+-binding loop of calmodulin, specifically the EF3 hand, which is essential for the signaling. Disrupting Ca2+ binding to EF3 abolishes the oxidation-induced enhancement of K(V)7.4 currents. Furthermore, the loading of EF3 with Ca2+ is critical for the reorientation of the AB fork, which translates the Ca2+ signals.

Summary: In this study, researchers investigated the behavior of Calbindin D-9k, a high-affinity modulator protein for Ca2+, and demonstrated that loop and helix II were necessary elements for the conformational change promoted by calcium. The fusion of chimeric motifs to an activity reporter gene indicated that the loop was the minimal element needed to induce a conformational change. The discrepancy between these results was discussed in terms of inter-motif interactions and the involvement of helix I in modulating Ca2+ affinity and restricting motif conformation.

Summary: In this study, we generated TcMICU1/TcMICU2 double knockout cell lines using CRISPR/Cas9 genome editing and found that these knockout cell lines were unable to uptake calcium at low extramitochondrial calcium concentrations. Further investigation revealed that Mg2+ negatively regulates the mitochondrial calcium uptake mediated by MCUC.

Summary: AP2 forms AP2 CCV with clathrin and other coat proteins, and synapses contain different types of CCV. The stability and composition of CCV are regulated by various factors, including Hsc70 and phosphorylation patterns. The knockout of the AP1/O1B complex disrupts synaptic vesicle recycling and endosomal protein sorting, leading to upregulation of endocytosis. Stable CCV, termed stCCV, have distinct characteristics and specialized functions in synaptic plasticity. The phosphorylation of Hsc70 and the levels of kinases play a crucial role in regulating the stability and disassembly of clathrin in CCV.

Summary: This study used a mass spectrometry-based approach to assess the differences in glycan features between extracellular vesicles (EVs) and originating cells. The results showed that EVs selectively enriched specific glycan features, particularly those associated with binding to the extracellular matrix. The study also found differences in EV glycan sorting between different metastatic cell lines and mouse models, indicating a potential role of glycan diversity in the metastatic process.

Summary: This study reveals that glioma-derived S100A9 can induce microglial M2 polarization, inhibit CD8+ T lymphocytes, and promote immunosuppression. The mechanism is related to the interaction with alpha v133 integrin and subsequent activation of AKT1 in microglia. The expression of S100A9 is positively associated with CD206 expression and negatively correlated with CD8+ T lymphocyte accumulation in the TME, suggesting a potential role of S100A9 in regulating the tumor microenvironment and immune evasion in glioma.

Summary: The replication of DNA requires a complex machinery called the replisome, which is highly conserved across species. One crucial component of the replisome is the CMG helicase complex, which unwinds DNA and coordinates the assembly and function of other replisome components. In this study, the impact of the absence of one copy of the CMG complex genes on the physiology and aging of yeast cells was investigated. The findings showed disruptions in the cell cycle, extended doubling times, and alterations in the biochemical profile of these cells. Importantly, it was found that heterozygous cells for CMG helicase genes exhibited increased reproductive potential and delayed aging. The study also highlighted potential therapeutic targets for cancer treatment using yeast.

Summary: The phosphorylation of p65 and the expression of SUMO1 are increased in cancer tissues of HCC patients, and there is a positive correlation between SUMO1 and phosphorylated p65. SUMOylation of p65 by SUMO1 promotes p65 nuclear import and enhances NF-xB activity. Both SUMOylation and phosphorylation of p65 increase the viability and invasion of hepatoma cells, and decrease cell apoptosis.

Summary: This study investigates the role of cyclic AMP (cAMP) in glycogen metabolism and reveals that cAMP regulates glycogenolysis in opposite directions depending on its site of synthesis within cells and downstream effectors. The canonical tmAC-cAMP-PKA signaling promotes glycogenolysis, while the non-canonical sAC-cAMP-Epac1 signaling suppresses glycogenolysis. This highlights the importance of cAMP microdomain organization for distinct metabolic regulation.
