The epigenetic modification of DNA or RNA may have relationship with the development of diabetic nephropathy (DN). We designed to develop a liquid chromatography mass spectrometry (LC-MS) coupled with mobile phase additive sensitization method for the analysis of the dissociative epigenetic modified nucleosides in serum of patients from different periods of DN with the health comparison. Serum samples were collected from 43 healthy volunteers and 156 patients, which divided into four groups. A succinic acid enhanced LC-MS/MS strategy was developed for the quantitative analysis of seven nucleosides in serum samples. The signal intensity of seven nucleosides increased three to seven times, respectively. A series of statistical analysis were carried out to demonstrate the dynamic changes of modified nucleosides in four groups. This method showed good specific, accuracy, and stability. The results were calibrated and presented through the formation of mA/C, I/C, 5-mdC/C, 5-mC/C, pseU/U to eliminate the individual and age differences. The mA/C, I/C, and pseU/U were found having the dynamic changes in four groups (p< 0.05). And these five modified nucleosides can also used as one parameter to distinguish these four groups by ROC and LDA analysis. Additionally, they were found to be connected with several clinical biochemical indexes through multiple linear regression analysis. Our LC-MS/MS method assay successfully quantifies the modified nucleosides in serum. And three modified nucleosides can act as the potential biomarkers to describe the development of DN and help to evaluate the diagnosis, treatment, and prognosis of DN in clinical.

Objective: Oxidative stress prompts breast cancer cells to adapt by raising the lethal threshold and enhancing the antioxidant mechanism, thereby enabling survival and continuous proliferation that facilitates tumor progression. Nrf2 and 8-OHdG are indicative of oxidative stress activity and impact the progression of breast cancer. We aimed to analyze the expression of Nrf2 and 8-OHdG in various T stages of breast cancer in our hospital.

Exactly two decades ago, the ability to use high-throughput RNA sequencing technology to identify sites of editing by ADARs was employed for the first time. Since that time, RNA sequencing has become a standard tool for researchers studying RNA biology and led to the discovery of RNA editing sites present in a multitude of organisms, across tissue types, and in disease. However, transcriptome-wide sequencing is not without limitations.

Site-directed RNA editing (SDRE) holds significant promise for treating genetic disorders resulting from point mutations. Gene therapy, for common genetic illnesses is becoming more popular and, although viable treatments for genetic disorders are scarce, stop codon mutation-related conditions may benefit from gene editing. Effective SDRE generally depends on introducing many guideRNA molecules relative to the target gene; however, large ratios cannot be achieved in the context of gene therapy applications.

Ribonucleic acid (RNA) plays a pivotal role in regulating biological processes within living systems, with modified nucleosides serving as critical modulators of various aspects of biological functions. Therefore, the development of efficient methodologies for late-stage, site-selective RNA modification is of considerable interest, as it facilitates the functional exploration of RNA chemical modifications and their implications for therapeutic applications. Precise RNA modification holds significant promise for the treatment of genetic diseases by enabling the correction of mutated nucleobases to their wild-type forms.

Osteosarcoma (OS) is the most commonly diagnosed primary malignant bone tumor in children and adolescents. Despite significant advancements in therapeutic strategies against OS over the past few decades, the prognosis for this disease remains poor, largely due to its high invasiveness and challenges associated with its treatment. N6-methyladenosine (m6A) modification is one of the most abundant epigenetic modifications of RNAs, and many studies have highlighted its crucial role in OS.
