Single-cell analysis unveils cell subtypes of acral melanoma cells at the early and late differentiation stages.

Background: Melanoma, a malignant neoplasm originating from melanocytes, is a form of skin cancer with rapidly increasing global incidence, often exacerbated by UV radiation[1]. Particularly, acral melanoma, characterized by its swift metastasis and poor prognosis, underscores the significance of further research into its heterogeneity. Single-cell sequencing has been widely utilized in the study of tumor heterogeneity; however, research related to melanoma remains to be further refined.

TtrAgo-mediated nucleic acid detection system and portable device for rapid detection of sexually transmitted diseases.

The development of rapid and multiplexed point-of-care (POC) diagnostic tools is vital for the prevention and control of sexually transmitted diseases (STIs). Here, we developed a POC-comprehensive Thermococcus thioreducensArgonaute (TtrAgo)-mediated nucleic acid detection system (POC-CANDY) and palm-sized portable detection device "Owl-1" for the simultaneous detection of Ureaplasma urealyticum, Chlamydia trachomatis, Neisseria gonorrhoeae, human papillomavirus types 16/18 and antibiotic resistance molecular markers [tetM, and gyrA mutation (S91F)]. Using recombinase polymerase amplification (RPA), the optimized POC-CANDY could finish the whole detection procedure within 55 min and achieve a limit of detection of 10 copies/μL.

Dual signal amplification in ECL biosensors: A novel approach for argonaute2 detection using SAHARA CRISPR-Cas12a technology.

Argonaute 2 (Ago2) is a crucial enzyme in the RNA interference (RNAi) pathway, essential for gene silencing via the cleavage of target messenger RNA (mRNA) mediated by microRNA (miRNA) or small interfering RNA (siRNA). The activity of Ago2 is a significant biomarker for various diseases, including cancer and viral infections, necessitating precise monitoring techniques. Traditional methods for detecting Ago2 activity are often cumbersome and lack the necessary sensitivity and specificity for low-abundance targets in complex samples.

Loss of LRRK2 activity induces cytoskeleton defects and oxidative stress during porcine oocyte maturation.

Leucine-rich repeat kinase 2 (LRRK2) is a ROCO family member which its mutation is closely related with Parkinson's disease, and LRRK2 is widely involved into the regulation of autophagy, vesicle transport and neuronal proliferation. However, the roles of LRRK2 during mammalian oocyte maturation are still largely unclear. In present study, we disturbed the activity of LRRK2 and showed its essential roles in porcine oocytes.

Tree shrew as a new animal model for musculoskeletal disorders and aging.

Intervertebral disc degeneration (IDD), osteoarthritis (OA), and osteoporosis (OP) are common musculoskeletal disorders (MSDs) with similar age-related risk factors, representing the leading causes of disability. However, successful therapeutic development and translation have been hampered by the lack of clinically-relevant animal models. In this study, we investigated the potential suitability of the tree shrew, a small mammal with a close genetic relationship to primates, as a new animal model for MSDs.

Co-Expression of Dominant-Negative TGF-β Receptor 2 Enhances the Therapeutic Efficacy of Novel TREM1/DAP12-BB-Based CAR-T Cells in Solid Tumours.

Chimeric antigen receptor (CAR) T-cell therapy has exhibited remarkable efficacy in the treatment of haematological malignancies, yet its application in solid tumours is hindered by the immunosuppressive tumour microenvironment (TME). In this study, a novel SS1-TREM1/DAP12-BB CAR-T cell was devised to target ovarian cancer and further engineered to co-express the dominant-negative TGF-β receptor 2 (DNR) to combat CAR-T cell exhaustion in TME. The incorporation of DNR effectively blocked TGF-β signalling, thereby enhancing CAR-T cell survival and antitumor activity in a TGF-β1-rich environment.

However, not all patients experience long-lasting benefits, underscoring the necessity to discover reliable biomarkers for predicting treatment outcomes.

Haplotype-Resolved Genotyping and Association Analysis of 1,020 β-Thalassemia Patients by Targeted Long-Read Sequencing.

Despite the well-documented mutation spectra of β-thalassemia, the genetic variants and haplotypes of globin gene clusters modulating its clinical heterogeneity remain incompletely illustrated. Here, a targeted long-read sequencing (T-LRS) is demonstrated to capture 20 genes/loci in 1,020 β-thalassemia patients. This panel permits not only identification of thalassemia mutations at 100% of sensitivity and specificity, but also detection of rare structural variants (SVs) and single nucleotide variants (SNVs) in modifier genes/loci.

Oxymatrine Inhibits Liver Cancer Progression by Regulating SIRT1/YY1/GPX4 Axis-Mediated Ferroptosis.

Ferroptosis is regarded as a promising cancer therapeutic target. As a major bioactive compound from traditional Chinese medicine (TCM) herb Aiton, oxymatrine (OMT) can depress inflammatory factors, reduce iron deposition, and suppress the hub gene or protein expression involved in ferroptosis and inflammation. Additionally, OMT can control collagen deposition in the liver and has a therapeutic effect on liver cancer.

Ankylosing Spondylitis (AS) and Systemic Sclerosis (SSc) are both autoimmune diseases, albeit with distinct anatomical targets. AS primarily affects the spine and sacroiliac joints, triggering inflammation and eventual fusion of the vertebrae. SSc predominantly impacts the skin and connective tissues, leading to skin fibrosis, thickening, and potential damage to vital organs such as the lungs, heart, and kidneys.

Roles and Mechanisms of Ferroptosis in Sorafenib Resistance for Hepatocellular Carcinoma.

Hepatocellular carcinoma (HCC) is the most prevalent malignant tumor, characterized by a poor prognosis. In recent decades, both the incidence and mortality rates of HCC have risen sharply. Sorafenib has emerged as the first conventional drug approved by the US Food and Drug Administration for first-line treatment in advanced HCC patients due to its favorable safety profile.

Inhibition of autophagy attenuates cognitive decline and mitochondrial dysfunction in an Alzheimer's disease mouse model with chronic cerebral hypoperfusion.

This study aimed to investigate the impact of chronic cerebral hypoperfusion (CCH) on cognitive function, amyloid-β (Aβ) deposition, cellular autophagy, and mitochondrial dynamics in an Alzheimer's disease (AD) mouse model, and to evaluate the intervention effects of autophagy modulation on these outcomes. Utilizing the APP/PS1 mouse model combined with CCH, we assessed cognitive function, Aβ deposition, and the expression levels of relevant proteins through behavioral tests and immunohistochemical analysis. Our findings revealed pronounced cognitive deficits and increased Aβ deposition in the AD + CCH group mice, along with upregulation of mitochondrial fission proteins (Drp1, Fis1) and downregulation of mitochondrial fusion proteins (Opa1, Mfn1), indicating a shift towards mitochondrial fission and promoting cell apoptosis.

The aim of this study was to reveal the structural characteristics of FAPP2, evaluate its expression in HepG2 and MHCC97H cells, and explore its potential role and molecular mechanism in the clinical treatment of hepatocellular carcinoma. The role of FAPP2 in these two cell lines was evaluated using cell function tests, such as cell proliferation, migration, and invasion tests.

Impact of anxiety symptoms on dialysis adherence and complication rates: A longitudinal observational study.

Background: Anxiety is a common psychological comorbidity in patients undergoing dialysis, yet its impact on treatment adherence and complication rates remains understudied. We designed a longitudinal observational study to investigate these relationships, based on the hypothesis that higher anxiety symptoms would be associated with increased complication rates and negatively associated with adherence to the dialysis regimen.

Aim: To investigate the relationship between anxiety symptoms, dialysis adherence, and complication rates in patients undergoing dialysis over a 24-month period.
