Conformational ensembles for protein structure prediction.

Acquisition of conformational ensembles for a protein is a challenging task, which is actually involving to the solution for protein folding problem and the study of intrinsically disordered protein. Despite AlphaFold with artificial intelligence acquired unprecedented accuracy to predict structures, its result is limited to a single state of conformation and it cannot provide multiple conformations to display protein intrinsic disorder. To overcome the barrier, a FiveFold approach was developed with a single sequence method.

Economic evaluation of newborn deafness gene screening as a public health intervention in China: a modelling study.

Background: While global newborn hearing screening programmes (NHSP) are far from the optimal level, the combined hearing and genetic screening has emerged as an innovative approach of early healthcare interventions. There is a clear need for economic evaluation to establish whether newborn deafness gene screening (NDGS), currently mandated by many cities in China, is a good investment.

Methods: A decision-tree model was constructed to simulate a hypothetical 10-million Chinese newborn cohort over a lifetime with three strategies: (1) no screening, (2) NHSP (standard screening) and (3) NHSP+NDGS (combined screening).

Dek570-1, a PPR-DYW protein, is required for maize seed and plant development via modulation of C-to-U RNA editing in mitochondria and chloroplasts.

Maize Dek570-1 affects the expression and function of organellar genes by performing cytidines-to-uridines RNA editing at specific sites of mitochondrial and chloroplast transcripts, thereby regulating seed and plant development. Cytidines-to-uridines (C-to-U) RNA editing at specific sites of mitochondrial and plastid transcripts is crucial for the expression and function of organellar genes, which requires PPR proteins. Here, we report the map-based cloning and characterization of Defective Kernel 570-1 (Dek570-1), which encodes a PPR-DYW protein and is an allele of Emp17.

Repressing cytokine storm-like response in macrophages by targeting the eIF2α-integrated stress response pathway.

Cytokine storm is a life-threatening systemic hyper-inflammatory state caused by different etiologies, in which the bulk production of pro-inflammatory cytokines from activated macrophages has a central role. Integrated stress response (ISR) comprises several protective signaling pathways, leading to phosphorylation of eukaryotic initiation factor 2α (eIF2α) and repression of protein translation. Emerging evidence suggests that ISR induction may elicit anti-inflammatory effects.

Synergistic SDT/cuproptosis therapy for liver hepatocellular carcinoma: enhanced antitumor efficacy and specific mechanisms.

The efficacy of sonodynamic therapy (SDT), an emerging approach for tumor treatment, is hindered by the high levels of the antioxidant glutathione (GSH) in the tumor microenvironment (TME). In this study, we constructed nanobubbles loaded with the sonosensitizer HMME and the tumor-targeting peptide RGD (HMME-RGD@CF NBs) for synergistic SDT/cuproptosis therapy of liver hepatocellular carcinoma (LIHC) in combination with Elesclomol-Cu as cuproptosis inducers. Endogenous GSH is consumed by Cu to modulate the complex TME, thereby amplifying oxidative stress and further improving SDT performance.
