Colorectal cancer (CRC) represents one of the most common malignancies with high morbidity worldwide. RNA methylation (m6A) has been considered to tremendously contribute to cancer initiation and progression since its first discovery. In this study, we comprehensively analyzed associations between mRNA expressions of m6A regulators and CRC tumor samples' epidemiologic information from the Cancer Genome Atlas (TCGA). Multivariate Cox proportional hazard model was applied to screening of m6A regulators whose mRNA expressions were significantly associated with CRC tumor samples' overall survival (OS) probability and those significant regulators were used for LASSO regression analysis to construct CRC prognosis prediction signature. As a result, two regulators i.e., YTHDC2 and ALKBH5 were picked out in multivariate analysis. CRC prognosis signature was constructed based on those two regulators through which CRC tumor samples with favorable and inferior prognosis could definitely be distinguished independent of potential confounding factors. This study should be helpful for identifying prognostic different CRC patients and guiding therapeutic method selection.

Background/aims: Colon adenocarcinoma (COAD) is a prevalent malignant tumor of the digestive system. Previous research has indicated that RNA N6-methyladenosine (m6A) methyltransferase RNA-binding motif protein-15 (RBM15) is involved in various cancers. We aimed to investigate the function of RBM15 in COAD progression and its underlying molecular mechanism.

As a widely epigenetic modification, mA (N-methyladenosine, mA) can regulate the degradation, translation, and other biological functions of circRNAs through dynamic reversible processes. It plays an important role in regulating the life activities of biological organisms, particularly in cell differentiation, apoptosis, embryonic development, stress response, and innate immunity. In this study, bioinformatics analysis, qRT-PCR identification, FISH subcellular localization, and ceRNA network construction were performed on mA modified circRNAs regulating the apoptosis of secondary hair follicle cells of Inner Mongolia Albas white cashmere goats based on the skin mA sequencing data of secondary hair follicles in anagen and catagen.

Acute kidney injury (AKI) is one of the most serious and common complications in the course of sepsis, known for its poor prognosis and high mortality rate. Recently, ferroptosis, as a newly discovered regulatory cell death, might be closely associated with the progression of AKI. METTL14 is a writer of RNA m6A, an abundant epigenetic modification in transcriptome with broad function.
