TL;DR: Overall, this study establishes the CDK4/6–DUB3 axis as an important regulatory mechanism of breast cancer metastasis and provides a rationale for potential therapeutic interventions in the treatment of breast Cancer metastasis.
Abstract: Tumour metastasis, the spread of cancer cells from the original tumour site followed by growth of secondary tumours at distant organs, is the primary cause of cancer-related deaths and remains poorly understood. Here we demonstrate that inhibition of CDK4/6 blocks breast tumour metastasis in the triple-negative breast cancer model, without affecting tumour growth. Mechanistically, we identify a deubiquitinase, DUB3, as a target of CDK4/6; CDK4/6-mediated activation of DUB3 is essential to deubiquitinate and stabilize SNAIL1, a key factor promoting epithelial-mesenchymal transition and breast cancer metastasis. Overall, our study establishes the CDK4/6-DUB3 axis as an important regulatory mechanism of breast cancer metastasis and provides a rationale for potential therapeutic interventions in the treatment of breast cancer metastasis.

TL;DR: Molecular modeling and experimental investigation of aminothiazolquinolone 12b with DNA from a sensitive methicillin-resistant Staphylococcus aureus (MRSA) strain revealed that the possible antibacterial mechanism might be related to the formation of a compound 12b-Cu(2+)-DNA ternary complex.
Abstract: A series of novel 3-aminothiazolquinolones as analogues of quinolone antibacterial agents were designed and synthesized in an effort to circumvent quinolone resistance. Among these 3-aminothiazolquinolones, 3-(2-aminothiazol-4-yl)-7-chloro-6-(pyrrolidin-1-yl) quinolone 12b exhibited potent antibacterial activity, low cytotoxicity to hepatocyte cells, strong inhibitory potency to DNA gyrase, and a broad antimicrobial spectrum including against multidrug-resistant strains. This active molecule 12b also induced bacterial resistance more slowly than norfloxacin. Analysis of structure–activity relationships (SARs) disclosed that the 2-aminothiazole fragment at the 3-position of quinolone plays an important role in exerting antibacterial activity. Molecular modeling and experimental investigation of aminothiazolquinolone 12b with DNA from a sensitive methicillin-resistant Staphylococcus aureus (MRSA) strain revealed that the possible antibacterial mechanism might be related to the formation of a compound 12b–Cu...

TL;DR: Direct electron transfer of hemin to the electrode during the potential scan can generate significantly amplified current for sensitive detection of thrombin at the low picomolar level and can offer new opportunities for the development of convenient signal amplification strategies for detecting various protein targets.
Abstract: Thrombin plays important roles for the diagnosis of neurodegenerative and cardiovascular diseases. By integrating proximity binding-induced strand displacement and metal ion-dependent DNAzyme recycling amplification, we demonstrate here the development of a simple and sensitive strategy for the detection of thrombin in human serums. The binding of the two distinct aptamers to the thrombin targets increases the local concentration of the aptamers and facilitates the release of the enzymatic sequences through proximity binding-induced strand displacement. The liberated enzymatic sequences further hybridize with the G-quadruplex containing and hairpin-structured substrate sequences on the sensor electrode to form the metal-ion dependent DNAzymes. Subsequently, the metal ions catalyze the cleavage of the substrate sequences to unlock the G-quadruplex forming sequences and to release the enzymatic sequences to trigger another cleavage cycle. Such metal ion-dependent DNAzyme recycling amplification leads to the...

TL;DR: FMRI and graph theory suggested that MDD was associated with disruptions in the topological structure of functional brain networks, and provided new insights concerning the pathophysiological mechanisms of MDD.
Abstract: Recent developments in graph theory have heightened the need for investigating the disruptions in the topological structure of functional brain network in major depressive disorder (MDD). In this study, we employed resting-state functional magnetic resonance imaging (fMRI) and graph theory to examine the whole-brain functional networks among 42 MDD patients and 42 healthy controls. Our results showed that compared with healthy controls, MDD patients showed higher local efficiency and modularity. Furthermore, MDD patients showed altered nodal centralities of many brain regions, including hippocampus, temporal cortex, anterior cingulate gyrus and dorsolateral prefrontal gyrus, mainly located in default mode network and cognitive control network. Together, our results suggested that MDD was associated with disruptions in the topological structure of functional brain networks, and provided new insights concerning the pathophysiological mechanisms of MDD.

TL;DR: The results indicate the potential for producing recombinant spider silk in transgenic B. mori and show a higher tensile strength and elasticity than wild-type silk.
Abstract: Spider dragline silk is a unique fibrous protein with a combination of tensile strength and elasticity, but the isolation of large amounts of silk from spiders is not feasible. In this study, we generated germline-transgenic silkworms (Bombyx mori) that spun cocoons containing recombinant spider silk. A piggyBac-based transformation vector was constructed that carried spider dragline silk (MaSp1) cDNA driven by the sericin 1 promoter. Silkworm eggs were injected with the vector, producing transgenic silkworms displaying DsRed fluorescence in their eyes. Genotyping analysis confirmed the integration of the MaSp1 gene into the genome of the transgenic silkworms, and silk protein analysis revealed its expression and secretion in the cocoon. Compared with wild-type silk, the recombinant silk displayed a higher tensile strength and elasticity. The results indicate the potential for producing recombinant spider silk in transgenic B. mori.
