Detection of lead contamination using DNAzyme and split activator-triggered CRISPR/Cas12a.

Widespread Pb contamination represents a significant global health threat, particularly to children, highlighting the critical need for accurate monitoring and quantification to mitigate its adverse effects. The integration of DNAzymes with the programmable nuclease Cas12a has emerged as a promising approach for achieving specific and ultrasensitive detection of Pb. However, conventional DNAzyme-Cas12a systems suffer from inevitable background signals caused by dynamic instability between DNAzymes and Cas12a activators, which compromises analytical reliability.

Ultrasensitive RNase H activity detection using the transcription-based hybrid probe and CRISPR/cas12a signal amplifier.

Ribonuclease H (RNase H), a critical functional protein in replication and genome stability, is emerging as a crucial therapeutic target for various diseases, including immune disorders. We present a transcription-based hybrid probe, referred to as Hybprobe, and a CRISPR/Cas12a signal amplifier for the rapid, sensitive, and low-cost detection of RNase H activity. In this method, the RNA strand of the Hybprobe is specifically cleaved by RNase H, releasing a single-stranded DNA activator that facilitates recognition and cleavage by the Cas12a/crRNA complex, triggering signal amplification via Cas12a's trans-cleavage activity.

The transcription factor MEF2C restrains microglial overactivation by inhibiting kinase CDK2.

Microglial intrinsic immune checkpoints are essential safeguards to maintain immune homeostasis by preventing microglial overactivation, a process that substantially influences neurological disorders such as autism spectrum disorder (ASD). MEF2C is a crucial immune checkpoint that regulates microglial activation, but the mechanism remains unclear. We found that MEF2C-deficient (MEF2C) induced microglia-like cells (iMGLs) derived from human pluripotent stem cells (hPSCs) exhibited overactivation following lipopolysaccharide stimulation, mimicking patterns observed in various neuroinflammatory disorders.

Brown adipose tissue alleviates podocyte apoptosis through NRG4 in a male mouse model of diabetic kidney disease.

Aims/hypothesis: Brown adipose tissue (BAT) consumes excess energy through heat production by uncoupling protein 1 (UCP1) to regulate the metabolic profile, but the UCP1-independent mechanisms of BAT, such as in endocrine function, are largely unknown. Our previous study showed that BAT-derived neuregulin 4 (NRG4) displays anti-atherosclerotic properties. Thus, we hypothesised that BAT could regulate diabetic nephropathy, a diabetic microvascular complication, via NRG4.

Change trends in serum phosphate levels predict in-hospital mortality in critically ill septic patients.

Serum phosphate levels are strongly correlated with the prognosis of septic patients. However, previous studies have concentrated on individual phosphate levels, and the relationship between change trends in serum phosphate levels and in-hospital mortality has seldom been reported. We aimed to investigate whether the level and change trends of serum phosphate were associated with in-hospital mortality.

Enhancing RNA editing efficiency and specificity with engineered ADAR2 guide RNAs.

RNA editing is a prospective therapeutic approach for correcting harmful mutations, offering the benefits of reversibility and tunability without permanently modifying the genome. However, the relatively low enzymatic activity and the occurrence of off-target editing events present significant challenges, limiting its utility. In response to this limitation, we introduced a novel strategy: strand displacement-responsive ADAR system for RNA editing (SPRING) by adding a "blocking sequence" to form a hairpin guide RNA.

Stigmasterol mitigates rheumatoid arthritis progression by decreasing Nrf2/NLRP3-mediated pyroptosis in chondrocyte.

Stigmasterol (Stig), a phytosterol with anti-inflammatory and antioxidant properties, has been shown to have potential therapeutic effects. In this study, we aimed to investigate whether Stig mitigates rheumatoid arthritis (RA) progression by reducing chondrocyte injury. A mouse model of RA was established by intradermally injecting type II collagen into the tail roots of mice.

Therapeutic Reprogramming toward Regenerative Medicine.

Therapeutic reprogramming represents a transformative paradigm in regenerative medicine, developing new approaches in cell therapy, small molecule drugs, biologics, and gene therapy to address unmet medical challenges. This paradigm encompasses the precise modulation of cellular fate and function to either generate safe and functional cells for cell-based therapies or to directly reprogram endogenous cells or for tissue repair and regeneration. Building on the discovery of induced pluripotent stem cells (iPSCs), advancements in chemical modulation and CRISPR-based gene editing have propelled a new iterative medicine paradigm, focusing on developing scalable, standardized cell therapy products from universal starting materials and enabling iterative improvements for more effective therapeutic profiles.

Integrating commercial personal glucose meter with peroxidase-mimic DNAzyme to develop a versatile point-of-care biosensing platform.

The development of point-of-care testing (POCT) methods is highly desirable in molecular detection, as they enable disease diagnosis and biomarker monitoring on-site or at home. Repurposing existing POCT devices to detect diverse biomarkers is an economical way to develop new devices for POCT use. Personal glucose meter (PGM) is one of the most used off-the-shelf POCT devices that has been reused to detect non-glucose targets.

Single-cell multi-omics deciphers hepatocyte dedifferentiation and illuminates maintenance strategies.

Due to the similarity to human hepatocytes, porcine hepatocytes play an important role in hepatic research and drug evaluation. However, once hepatocytes were cultured in vitro, it was often prone to dedifferentiate, resulting in the loss of their characteristic features and normal functions, which impede their application in liver transplantation and hepatotoxic drugs evaluation. Up to now, this process has yet to be thoroughly investigated from the single-cell resolution and multi-omics perspective.

Association between red blood cell distribution width and mortality in severe osteomyelitis patients.

Red blood cell distribution width (RDW) is considered to be associated with the prognosis of patients with severe infections. This study aims to investigate the relationship between RDW and prognosis in osteomyelitis patients admitted to the ICU. Through a retrospective cohort study, relevant records of severe osteomyelitis patients were collected from the Medical Information Mart for Intensive Care (MIMIC-IV) database.

Pharmacologically inducing regenerative cardiac cells by small molecule drugs.

Adult mammals, unlike some lower organisms, lack the ability to regenerate damaged hearts through cardiomyocytes (CMs) dedifferentiation into cells with regenerative capacity. Developing conditions to induce such naturally unavailable cells with potential to proliferate and differentiate into CMs, that is, regenerative cardiac cells (RCCs), in mammals will provide new insights and tools for heart regeneration research. In this study, we demonstrate that a two-compound combination, CHIR99021 and A-485 (2C), effectively induces RCCs from human embryonic stem cell-derived TNNT2 CMs in vitro, as evidenced by lineage tracing experiments.
