Due to oxidative damage and mitochondrial dysfunction, boar semen cryopreservation remains a significant challenge. This study investigates the effects of pyrroloquinoline quinone (PQQ), mitochondrial-targeted antioxidant, on post-thaw sperm quality during cryopreservation. Boar was diluted in freezing extender containing different concentrations PQQ (0, 10, 100, 1000, 10,000 nM). After freezing-thawing, motility, viability, acrosome integrity, activity, adenosine triphosphate (ATP) levels,...

Microtubule-based transport by the kinesin motors, powered ATP hydrolysis, is essential for a wide range of vital processes in eukaryotes. We obtained insight into this process developing atomic models no-nucleotide and states monomeric motor domain on microtubules from cryo-EM reconstructions at 5-6 Å resolution. By comparing these with existing X-ray structures ADP-bound kinesin, we infer mechanistic scheme which microtubule attachment, mediated universally conserved 'linchpin' residue...

Septin 9 (SEPT9) interacts with microtubules (MTs) and is mutated in hereditary neuralgic amyotrophy (HNA), an autosomal-dominant neuropathy. The mechanism of SEPT9 interaction MTs the molecular basis HNA are unknown. Here, we show that N-terminal domain contains novel repeat motifs K/R-x-x-E/D R/K-R-x-E, which bind bundle by interacting acidic C-terminal tails β-tubulin. Alanine scanning mutagenesis revealed K/R-R/x-x-E/D pair electrostatically one another β-tubulin, enabling septin–septin...

Myosin X has features not found in other myosins. Its structure must underlie its unique ability to generate filopodia, which are essential for neuritogenesis, wound healing, cancer metastasis and some pathogenic infections. By determining high-resolution structures of key components this motor, characterizing the vitro behaviour native dimer, we identify that explain myosin dimer behaviour. Single-molecule studies demonstrate a moves on actin bundles with higher velocities takes larger...

The DNA-origami technique has enabled the engineering of transmembrane nanopores with programmable size and functionality, showing promise in building biosensors synthetic cells. However, it remains challenging to build large (>10 nm), functionalizable that spontaneously perforate lipid membranes. Here, we take advantage pneumolysin (PLY), a bacterial toxin potently forms wide ring-like channels on cell membranes, construct hybrid DNA-protein nanopores. This PLY-DNA-origami complex, which...

Abstract Sperm are susceptible to excessive reactive oxygen species (ROS). Spermine and spermidine secreted in large amounts by the prostate potent natural free radical scavengers protect cells against redox disorder. Thus, we used boar sperm as a model study polyamines uptake elucidate whether protected from ROS stress. Seven mature fertile Duroc boars (aged 15 30 mo) were this study. In experiment 1, spermine (3.6 ± 0.3 3.3 0.2 mmol/L, respectively) abundant seminal plasma, content of...

Significance Pore-forming toxins are a common type of bacterial and important virulence factors. Aerolysin is produced by Aeromonas species. It interesting that aerolysin-like proteins also found in vertebrates. However, the physiological roles these still unknown. Previously, βγ-crystallin fused protein (α-subunit) trefoil factor (β-subunit) complex, hence named βγ-CAT, was identified frogs. Here, we this complex inducible challenge.

Abstract Circular RNAs (circRNAs) serve as competing endogenous (ceRNAs) and indirectly regulate gene expression through shared microRNAs (miRNAs). However, the potential circRNAs functioning ceRNAs in osteoporosis remain unclear. The bone marrow mesenchymal stem cells (BMSCs) were isolated from ovariectomy ( OVX) mice controls. We systematically analyzed RNA‐seq miRNA‐microarray data, miRNA‐target interactions, prominently coexpressed pairs to identify aberrantly expressed circRNAs, miRNAs,...
