The use of synthetic biomarkers is an emerging technique to improve disease diagnosis. Here, we report a novel design strategy that uses analyte-responsive acetaminophen (APAP) to expand the catalogue of analytes available for synthetic biomarker development. As proof-of-concept, we designed hydrogen peroxide (H O )-responsive APAP (HR-APAP) and succeeded in H O detection with cellular and animal experiments. In fact, for blood samples following HR-APAP injection, we demonstrated that the plasma concentration ratio [APAP+APAP conjugates]/[HR-APAP] accurately reflects in vivo differences in H O levels. We anticipate that our practical methodology will be broadly useful for the preparation of various synthetic biomarkers.

Background: Glycogen storage disease (GSD) Ia is an ultra-rare inherited disorder of carbohydrate metabolism. Patients often present in the first months of life with fasting hypoketotic hypoglycemia and hepatomegaly. The diagnosis of GSD Ia relies on a combination of different biomarkers, mostly routine clinical chemical markers and subsequent genetic confirmation.

To create a diagnostic tool before biopsy for patients with prostate-specific antigen (PSA) levels < 20 ng/ml to minimize prostate biopsy-related discomfort and risks. Data from 655 patients who underwent transperineal prostate biopsy at the First Affiliated Hospital of Wannan Medical College from July 2021 to January 2023 were collected and analyzed. After applying the Synthetic Minority Over-sampling TEchnique class balancing on the training set, multiple machine learning models were constructed by using the Least Absolute Shrinkage and Selection Operator (LASSO) feature selection to identify the significant variables.

Background & Aims: The ubiquitin receptor ADRM1/Rpn13 governs the specificity of eukaryotic protein degradation. By SMRT sequencing, we first discovered a novel spliced variant of ADRM1 with a skipped exon 9, termed ADRM1-ΔEx9, in human hepatocellular carcinoma (HCC). This study aimed to elucidate this novel ubiquitin receptor's underlying biology and clinical implications in HCC.

In Silico Method for ssDNA Aptamer Binding with Aurora Kinase A Protein.

Methods Mol Biol

January 2025

Department of Biotechnology, College of Natural and Applied Science, Addis Ababa Science and Technology University, Addis Ababa, Ethiopia.

While traditional assay methods face challenges in detecting specific proteins, aptamers, known for their high specificity and affinity, are emerging as a valuable biomarker detection tool. Aurora kinase A (AURKA) plays a role in cell division and influences stem cell reprogramming. In this study, an in silico approach method was conducted for a random ssDNA aptamer sequence selection and its binding with AURKA.
