Summary: This study discovered three active prokaryotic Argonautes (pAgos) with about 50% sequence identity to KmAgo, which have typical DNA-guided DNA target cleavage ability. Among them, RsuAgo from Rummeliibacillus suwonensis was mainly explored for its ability to cleave both DNA and RNA targets, especially with short guide DNAs in the range of 16-20 nt. RsuAgo-mediated RNA target cleavage showed a preference for a guide strand with a 5'-terminal A residue. Furthermore, RsuAgo was found to be able to cleave double-stranded DNA in a low-salt buffer at 37 degrees C, providing a new tool for DNA and RNA manipulation at moderate temperatures.

Summary: This study investigated the impact of high endogenous DNase activity on an animal model of acute liver failure. It was found that mice with higher DNase activity had lower mortality after 48 hours. The study also suggested that vesicles or DNA-binding proteins may play a role in protecting ecDNA from nucleases.

Summary: CRISPR-Cas9 is a versatile ribonucleoprotein complex used in various biological techniques, but its stable binding to DNA after cleavage poses a challenge in genome editing applications. Research shows that different Cas9 variants exhibit different release mechanisms after DNA cleavage, with post-cleavage state demonstrating higher stability. This study provides insights into the binding stability of Cas9 and its variants, shedding light on their potential applications in genome editing.

Summary: The crystallographic structures of Cas9 bound to off-target substrates reveal that noncanonical base-pairing interactions within the guide:off-target heteroduplex enable off-target binding. Single-nucleotide deletions in off-target substrates are accommodated by base skipping or multiple noncanonical base pairs. PAM-distal mismatches result in duplex unpairing and induce a conformational change in the Cas9 REC lobe. These insights contribute to the improved rational design of guide RNAs and off-target prediction algorithms.

Summary: Heme proteins have shown promising potential as artificial metalloenzymes for catalyzing various reactions. In this study, reconstitution of myoglobin with sodium copper cholorophyllin resulted in a new artificial enzyme CuCP-L29E Mb, which exhibited hydrolytic DNA cleavage activity independently of O-2. The DNA cleavage activity of CuCP-L29E Mb was effectively promoted by Mg2+ ions, whereas the wild-type Mb reconstituted with CuCP showed no DNA cleavage activity. This study highlights the critical role of Mg2+ ions and the Glu29 ligand in the nuclease activity of CuCP-L29E Mb, suggesting potential applications for the artificial nuclease in the future.

Summary: Enhancing the cytotoxicity of metal complexes to cancer cells by fine-tuning structural and chemical properties is crucial. Copper complexes with intercalating ligands, such as [Cu(2CP-Bz-SMe)](2+), have shown superior DNA binding ability and efficient ROS generation for effective degradation of DNA. The synergistic effect of ROS generation and DNA intercalation contributes to the low IC50 values against various cancer cell lines, indicating a promising strategy for improved chemotherapy.

Summary: A mononuclear mixed ligand copper(II) complex, [Cu(L)(Hdpa)](ClO4), with a tridentate NNO donor ligand (H(L)) and 2,2'-dipyridylamine (Hdpa), has been synthesized. The complex has a square pyramidal coordination geometry with a CuN4O chromophore. It forms self-assembled inter-pair dimers in solid-state and solution due to stacking interactions and hydrogen bonding. The complex exhibits reversible oxidation state change (Cu(II)(->)(<-)Cu(I)) at high positive redox potentials and acts as an efficient catalyst for oxidation reactions.

Summary: Generation of the 3' overhang is a crucial step in homologous recombination and replication fork rescue processes. In archaea, the nuclease NurA and ATPase HerA, along with the highly conserved MRE11/RAD50 proteins, play a significant role in producing 3' single-stranded DNA during homologous recombination. The single-strand binding protein SSB regulates the DNA repair process by inhibiting the activities of NurA and HerA.

Summary: This study investigated the antineoplastic activity of two platinum complexes containing alpha- and beta-naphthyl groups. The results showed that one of the platinum complexes exhibited higher cytotoxicity against all cancer cell lines tested and lower cytotoxicity against normal peripheral blood mononuclear cells. Further investigations revealed that this complex induced cell death by apoptosis and was associated with mitochondrial membrane depolarization, elevated levels of reactive oxygen species (ROS), and caspase activation.

Summary: This study presents the antioxidant activity of two manganese complexes [Mn(III)(bpa)2]Cl.H2O (1) and [(Cl)Mn(mu-hbpclnol)(mu-bpclnol)Mn](ClO4).3H2O (2) towards H2O2, superoxide anion radical, hydroxyl and DPPH. Both complexes demonstrated similar or better activities than the reference complex [Mn(salen)Cl] when tested against ROS (H2O2, O2•-, and •OH) by EPR in PBS, DMSO, and water. Complex (2) showed the highest scavenging activity towards hydroxyl and inhibited lipid peroxidation, as confirmed by TBARS assay. The results suggest that complexes (1) and (2) protect tissues from lipid peroxidation at the nanomolar scale, making them promising candidates for in vivo studies.

Summary: By hybridizing TiO2 photocatalyst with CaCO3 as the wall material and using linseed oil as the core material, self-cleaning and self-repairing microcapsules were produced using in-situ precipitation. The microcapsules were evaluated for their morphology, chemical composition, thermal stability, and self-cleaning and self-repairing properties. Results showed that the microcapsules had a rough and spherical surface, along with excellent thermal stability and repeatability. Increasing the dosage of microcapsules significantly increased the degradation rate of methylene blue, while the self-repairing effect of micro-cracks became more evident. The optimal microcapsule dosage was found to be 7.0 wt%.

Summary: The development of the textile industry has raised concerns due to the contamination of drinking water by organic dyes, which pose a carcinogenic risk to humans. Nanomaterials, particularly semiconductors, have been utilized for photocatalytic degradation of dye pollutants. Various parameters, such as catalyst dosage, irradiation time, light sources, initial dye concentration, temperature, and pH, play significant roles in the degradation process. Different generations of photocatalytic nanomaterials, including single metal nanoparticles, binary and ternary metal oxides, as well as inert solid substrates with photocatalysts, have been employed for dye degradation.
