Unveiling the unusual i-motif-derived architecture of a DNA aptamer exhibiting high affinity for influenza A virus.

Non-canonical nucleic acid structures play significant roles in cellular processes through selective interactions with proteins. While both natural and artificial G-quadruplexes have been extensively studied, the functions of i-motifs remain less understood. This study investigates the artificial aptamer BV42, which binds strongly to influenza A virus hemagglutinin and unexpectedly retains its i-motif structure even at neutral pH.

Meta-analysis of gut microbiota alterations in patients with irritable bowel syndrome.

Introduction: Irritable bowel syndrome (IBS) is a common chronic disorder of gastrointestinal function with a high prevalence worldwide. Due to its complex pathogenesis and heterogeneity, there is urrently no consensus in IBS research.

Dinuclear Dicationic Iridium Complexes for Highly Synergistic Photodynamic and Photothermal Therapy to Chemoresistant Cancer.

A series of dinuclear Ir(III) complexes have been constructed for enhanced photodynamic and photothermal therapy (PDT and PTT) for cisplatin-resistant non-small-cell lung cancer. They enter cells via caveolar endocytosis, target mitochondria but not nuclear, generate both singlet oxygen and superoxide anion, and release heat when exposed to infrared (IR) irradiation, thus inducing reactive oxygen species (ROS)-associated cell disruption and thermal ablation. The IR-generated ROS can further activate caspases, triggering apoptosis.

p53: The Multifaceted Roles of Covalent Modifications in Cancer.

The p53 protein has attracted huge research interest over several decades due to its role as one of the most important tumor suppressors in mammals, which orchestrates a synchronous response from normal cells in the body to various forms of stress. The diverse cellular activities of the p53 protein are regulated mainly via its post-translational modifications (PTMs). PTMs affect p53 on several levels: at the level of the assembly of tetrameric complexes on DNA to transactivate its target genes, at the level of the assembly of tetrameric complexes on DNA to transactivate its target genes; at the level of proteolysis in the absence of stress; and on the contrary, at the level of augmented protein stability in response to stress signals.

Fractional modelling of COVID-19 transmission incorporating asymptomatic and super-spreader individuals.

The COVID-19 pandemic has presented unprecedented challenges worldwide, necessitating effective modelling approaches to understand and control its transmission dynamics. In this study, we propose a novel approach that integrates asymptomatic and super-spreader individuals in a single compartmental model. We highlight the advantages of utilizing incommensurate fractional order derivatives in ordinary differential equations, including increased flexibility in capturing disease dynamics and refined memory effects in the transmission process.

Phenylpropanoid dimers from Chrysanthemum indicum with antioxidant effects via activating the Nrf2 signaling pathway.

Five phenylpropanoid dimers chrysanthephenyls A-E, with the 1-O-1'-type (1) and 1-O-2'-type (2-5) ether bond linking modes, were isolated from the aerial parts of Chrysanthemum indicum. Among them, chrysanthephenyls D and E were two pairs of enantiomers, and chrysanthephenyl E was further resolved into its enantiomers (+)-chrysanthephenyl E and (-)-chrysanthephenyl E via chiral-phase HPLC. Their structures were characterized on the basic analysis of the spectroscopic techniques (IR, HRESIMS, 1D and 2D NMR), and their absolute configurations were determined by DP4+ NMR analysis and ECD calculation method.

Homology modeling of the orthoflavivirus NS1 protein for virtual screening of potential ligands.

The orthoflavivirus NS1 protein is a relatively understudied target for the design of broad-spectrum anti-orthoflaviviral drugs. Currently, the NS1 protein structures of tick-borne orthoflaviviruses have not been published yet, but these structures can be modelled by homology, thus generating a large amount of structural data. We performed homology modelling of the NS1 protein structures of epidemiologically significant orthoflaviviruses and analysed the possibility of using these models in ensemble docking-based virtual screening.

T-cadherin modulates adipogenic differentiation in mesenchymal stem cells: insights into ligand interactions.

Introduction: T-cadherin, a non-canonical member of the cadherin superfamily, was initially identified for its involvement in homophilic recognition within the nervous and vascular systems. Apart from its adhesive function, T-cadherin acts as a receptor for two ligands: LDL, contributing to atherogenic processes, and HMW adiponectin, a hormone with well-known cardiovascular protective properties. However, the precise role of T-cadherin in adipose tissue remains elusive.
