MicroRNA (miRNA) is a promising biomarker for the early diagnosis of pancreatic cancer. To enable sensitive and reliable miRNA detection, we have developed a one-pot isothermal CRISPR/Dx detection system by combining rolling circle amplification (RCA) and CRISPR/Cas12a. RCA and CRISPR/Cas12a reactions are carried out in a single closed tube, bypassing the transferring step.

Data augmentation is a crucial regularization technique for deep neural networks, particularly in medical imaging tasks with limited data. Deep learning models are highly effective at linearizing features, enabling the alteration of feature semantics through the shifting of latent space representations-an approach known as semantic data augmentation (SDA). The paradigm of SDA involves shifting features in a specified direction.

Article Synopsis
  • The study investigates the biotoxicity of nanoplastics (NPs) and introduces a machine learning-based technique called "shrink-restricted" SERS (SRSS) to analyze cellular changes when exposed to different types of NPs.
  • It finds that environmentally sourced NPs are more toxic to specific cell lines, particularly due to their ability to carry harmful pollutants, which alters the death pathways of the cells.
  • The research highlights the effectiveness of this new method over traditional assays by providing real-time insights into cellular responses, improving understanding of the risks of plastic pollution.

Myelin sheath, as the multilayer dense structure enclosing axons in humans and other higher organisms, may rupture due to various injury factors after spinal cord injury, thus producing myelin debris. The myelin debris contains a variety of myelin-associated inhibitors (MAIs) and lipid, all inhibiting the repair after spinal cord injury. Through summary and analysis, the present authors found that the inhibition of myelin debris can be mainly divided into two categories: firstly, the direct inhibition mediated by MAIs; secondly, the indirect inhibition mediated by lipid such as cholesterol.

To address the challenge of chiral recognition in terms of efficiency and generality, we propose a novel fluorescence sensing approach by rationally designing metal-ion-responsive chiral molecular tweezers. The flexible and adaptable molecular tweezers enable facile recognition of 31 structurally varied chiral primary amine compounds, including amino acids, amino acid esters, and chiral amines. Notably, upon stimulation by zinc ions, the chiral molecular tweezers demonstrate a higher enantioselective fluorescence response.

Phenylketonuria (PKU) is a liver metabolic disorder mainly caused by a deficiency of the hepatic phenylalanine hydroxylase (PAH) enzyme activity, often leading to severe brain function impairment in patients if untreated or if treatment is delayed. In this study, we utilized dual-AAV8 vectors to deliver a near PAM-less adenine base editor variant, known as ABE8e-SpRY, to treat the Pah PKU mouse model carrying a frequent R408W mutation in the Pah gene. Our findings revealed that a single intravenous injection in adult mice and a single intraperitoneal injection in neonatal mice resulted in 19.

Although immune checkpoint inhibitors (ICIs) have demonstrated efficacy in treating advanced cancers, their therapeutic success remains limited for many patients, with initial responders often experiencing resistance and relapse. Interleukin-12 (IL-12) is a powerful cytokine for antitumor immunotherapy, enhancing both lymphocyte recruitment into tumors and immune cell activation. In this study, we successfully produced mouse interleukin-12 (mIL12) through eukaryotic recombinant expression.

1,2-Dichloroethane (1,2-DCE), a prevalent industrial and environmental contaminant, induces toxic encephalopathy through inhalation, leading to neurotoxic effects and inflammation-driven brain edema. Human umbilical cord mesenchymal stem cells (HUCMSCs) secrete bioactive factors, including miRNAs, proteins, and lipids via exosomes, exhibiting anti-inflammatory and immune-regulatory properties. However, their potential in treating 1,2-DCE-induced neuroinflammation and the underlying mechanisms remain unclear.

Synthetic Notch (synNotch) receptors have enabled mammalian cells to sense extracellular ligands and respond by activating user-prescribed transcriptional programs. Based on the synNotch system, we describe a cell-based in vivo sensor for cancerous cell detection. We attempted to engineer synNotch-programmed macrophages to sense cancer cells via urinary analysis of human chorionic gonadotropin (HCGB5).

Sialyltransferases are enzymes that play a crucial role in regulating cancer progression by modifying glycoproteins through sialylation. In particular, the ST3 beta-galactoside alpha-2,3-sialyltransferase 4 (ST3GAL4) enzyme is known to be upregulated in breast cancer, but its specific biological functions have not been fully understood. This study aimed to investigate the impact and mechanisms of ST3GAL4 on aerobic glycolysis in breast cancer.

Unlabelled: Hepatitis B virus (HBV) infection is a significant global health concern due to elevated immunosuppressive viral antigen levels, the host immune system's inability to manage HBV, and the liver's immunosuppressive conditions. While immunotherapies utilizing broadly reactive HBV neutralizing antibodies present potential due to their antiviral capabilities and Fc-dependent vaccinal effects, they necessitate prolonged and frequent dosing to achieve optimal therapeutic outcomes. Toll-like receptor 7/8 (TLR7/8) agonists have been demonstrated promise for the cure of chronic hepatitis B, but their systemic use often leads to intense side effects.
