AI Article Synopsis

  • Alternative polyadenylation (APA) significantly influences gene expression in eukaryotes, impacting processes like cell growth and differentiation, but its role during metamorphosis remains unclear.
  • By analyzing RNA-seq data from embryos to maturation over 16 time points, researchers found 247 differentially expressed APA events and identified five distinct patterns, with the gradual elongation of the 3' UTR being the most prominent.
  • The study highlights complex APA mechanisms during metamorphosis, revealing a connection between these changes and pathways related to protein and energy metabolism, along with potential regulatory roles of specific miRNAs.

Article Abstract

As an important mechanism in the post-transcriptional regulation of eukaryotic gene expression, alternative polyadenylation (APA) plays a key role in biological processes such as cell proliferation and differentiation. However, the role and dynamic pattern of APA during metamorphosis are poorly understood. Here, RNA-seq data covering from the embryo to the maturation (16 time points) of were utilized. We identified 247 differentially expressed APA events between early and adult stages, and through fuzzy mean clustering analysis, we discovered five dynamic APA patterns. Among them, the gradual elongation of the 3'UTR is the major APA pattern that changes over time, and its genes are enriched in the pathways of protein and energy metabolism. Finally, we constructed mRNA-miRNA and PPI networks and detected several central miRNAs that may regulate development. Our results revealed the complex APA mechanisms in metamorphosis, shedding new light on post-transcriptional regulation of crustacean metamorphosis.

Comprehensive characterization of the transcriptional landscape in Alzheimer's disease (AD) brains.

Sci Adv

Department of Biostatistics and Health Data Science, School of Medicine, Indiana University, Indianapolis, IN 46202, USA.

Alzheimer's disease (AD) is the leading dementia among the elderly with complex origins. Despite extensive investigation into the AD-associated protein-coding genes, the involvement of noncoding RNAs (ncRNAs) and posttranscriptional modification (PTM) in AD pathogenesis remains unclear. Here, we comprehensively characterized the landscape of ncRNAs and PTM events in 1460 samples across six brain regions sourced from the Mount Sinai/JJ Peters VA Medical Center Brain Bank Study and Mayo cohorts, encompassing 33,321 long ncRNAs, 92,897 enhancer RNAs, 53,763 alternative polyadenylation events, and 900,221 A-to-I RNA editing events.

Background: Circular RNAs (circRNAs) play multifaceted roles to precisely control expression of broad gene networks. These highly stable molecules are often accumulated in the mammalian brain and thought to serve as "memory molecules" that govern the long process of aging. Mounting evidence demonstrated circRNA dysregulation in the postmortem brains of Alzheimer's disease (AD).

Background: Alternative cleavage and polyadenylation (APA) is a crucial post-transcriptional gene regulation mechanism that regulates gene expression in eukaryotes by increasing the diversity and complexity of both the transcriptome and proteome. Despite the development of more than a dozen experimental methods over the last decade to identify and quantify APA events, widespread adoption of these methods has been limited by technical, financial, and time constraints. Consequently, APA remains poorly understood in most eukaryotes.

RNA-binding protein quaking: a multifunctional regulator in tumour progression.

Ann Med

Department of Breast Surgery, Second Affiliated Hospital and Cancer Institute (Provincial Key Laboratory of Tumor Microenvironment and Immunotherapy, Key Laboratory of Cancer Prevention & Intervention, National Ministry of Education), Zhejiang University School of Medicine, Hangzhou, China.

Background: Quaking (QKI) is a member of the signal transduction and activators of RNA (STAR) family, performing a crucial multifunctional regulatory role in alternative splicing, mRNA precursor processing, mRNA transport and localization, mRNA stabilization, and translation during tumour progression. Abnormal QKI expression or fusion mutations lead to aberrant RNA and protein expression, thereby promoting tumour progression. However, in many types of tumour, QKI played a role as tumour suppressor, the regulatory role of QKI in tumour progression remains ambiguous.
