Article Abstract
Background: The newly discovered reversible N6-methyladenosine (mA) modification plays an important regulatory role in gene expression. Long non-coding RNAs (lncRNAs) participate in Marek's disease virus (MDV) replication but how mA modifications in lncRNAs are affected during MDV infection is currently unknown. Herein, we profiled the transcriptome-wide mA modification in lncRNAs in MDV-infected chicken embryo fibroblast (CEF) cells.
Results: Methylated RNA immunoprecipitation sequencing results revealed that the lncRNA mA modification is highly conserved with MDV infection increasing the expression of lncRNA mA modified sites compared to uninfected cell controls. Gene Ontology and the Kyoto Encyclopedia of Genes and Genomes pathway analysis revealed that lncRNA mA modifications were highly associated with signaling pathways associated with MDV infection.
Conclusions: In this study, the alterations seen in transcriptome-wide mA occurring in lncRNAs following MDV-infection suggest this process plays important regulatory roles during MDV replication. We report for the first time profiling of the alterations in transcriptome-wide mA modification in lncRNAs of MDV-infected CEF cells.

Diabetic nephropathy (DN) is a major complication of diabetes, imposing substantial socioeconomic and public health challenges. N6-methyladenosine (m6A) modification, a prevalent epigenetic mechanism, influences cellular processes and disease progression. Wilms' tumor 1-associating protein (WTAP), an m6A methyltransferase subunit, was investigated for its role in DN.

Bladder cancer (BlCa) exhibits a highly heterogeneous molecular landscape and treatment response, underlining the pressing need for personalized prognosis. N6-methyladenosine (m6A) constitutes the most abundant RNA modification, modulates RNA biology/metabolism, and maintains cellular homeostasis, with its dysregulation involved in cancer initiation and progression. Herein, we evaluated the clinical value of METTL3 m6A methyltransferase, the main catalytic component of m6A methylation machinery, in improving BlCa patients' risk stratification and prognosis.

Heat shock protein family A member 4-like (HSPA4L) has been shown to be overexpressed in osteoarthritis (OA) patients, but its role in OA process still unknown. Chondrocytes were stimulated with interleukin-1β (IL-1β) to mimic OA cell model in vitro, and rat was injected with monosodium iodoacetate (MIA) to construct OA rat model in vivo. The expression of HSPA4L, methyltransferase-like 3 (METTL3) and extracellular matrix (ECM)-related markers was examined by qRT-PCR or western blot.

RNA modifications, including N6-methyladenosine (m6A), 5-methylcytosine, and pseudouridine, serve as pivotal regulators of gene expression with significant implications for human health and disease. These dynamic modifications influence RNA stability, splicing, translation, and interactions, thereby orchestrating critical biological processes such as embryonic development, immune response, and cellular homeostasis. Dysregulation of RNA modifications is closely associated with a variety of pathologies.

Objectives: Hepatocellular carcinoma (HCC) is among the most frequently occurring malignant tumors of the digestive tract and is associated with an increased mortality rate worldwide. This study aimed to develop and validate a prognostic model based on immunogenic cell death (ICD)-related genes to predict patient survival and guide individualized treatment strategies for HCC.
Methods: ICD-related genes were identified from the GeneCards database using a relevance score threshold of >10.
