Evolutionary profiling of the U49 snoRNA gene [PDF]

Hereditas, 2003
Small nucleolar RNAs (snoRNAs) are involved in precursor ribosomal RNA (pre-rRNA) processing and rRNA base modifications (2'-O-ribose methylation and pseudouridylation). Their genomic organization show great flexibility: some are individually or polycistronically transcribed, while others are encoded within introns of other genes.

Epigenetic Regulation in the Pathogenesis of Renal Inflammation: Insights and Therapeutic Potentials

iNew Medicine, EarlyView.
ABSTRACT Renal inflammation is a common pathological process in various kidney diseases, often initiated by factors such as toxins, ischemia, or autoimmune reactions. This inflammatory response can result in structural damage and a rapid decline in renal function.

Intronic small nucleolar RNAs regulate host gene splicing through base pairing with their adjacent intronic sequences

Genome Biology, 2023
Background Small nucleolar RNAs (snoRNAs) are abundant noncoding RNAs best known for their involvement in ribosomal RNA maturation. In mammals, most expressed snoRNAs are embedded in introns of longer genes and produced through transcription and splicing

Distinct Pathways for snoRNA and mRNA Termination [PDF]

Molecular Cell, 2006
Transcription termination at mRNA genes is linked to polyadenylation. Cleavage at the poly(A) site generates an entry point for the Rat1/Xrn2 exonuclease, which degrades the downstream transcript to promote termination. Small nucleolar RNAs (snoRNAs) are also transcribed by RNA polymerase II but are not polyadenylated.

SnoRNAs from the filamentous fungus Neurospora crassa: structural, functional and evolutionary insights

BMC Genomics, 2009
Background SnoRNAs represent an excellent model for studying the structural and functional evolution of small non-coding RNAs involved in the post-transcriptional modification machinery for rRNAs and snRNAs in eukaryotic cells.

Comparative analysis of microRNAs in bovine colostrum and neonatal calf blood

Journal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND MicroRNAs (miRNAs) are short non‐coding RNAs that participate in a wide range of biological processes. MiRNAs are present in high concentrations in colostrum, and these may be potentially transferred to newborn calves being fed colostrum.

Inhibition of PHF1 promotes ferroptosis via IRES‐dependent Snail translation regulation in pancreatic ductal adenocarcinoma

VIEW, EarlyView.
PHF1 is a known epigenetic regulator involved in transcriptional silencing in cancer. In this study, we identified PHF1 as an oncogene that promotes PDAC progression and demonstrated that its inhibition induces ferroptosis. Mechanistically, PHF1 physically interacts with the FBL/NOP56/NOP58 snoRNP complex to enhance the IRES‐dependent translation of ...

Accurate identification of snoRNA targets using variational graph autoencoder to advance the redevelopment of traditional medicines

Frontiers in Pharmacology
Existing studies indicate that dysregulation or abnormal expression of small nucleolar RNA (snoRNA) is closely associated with various diseases, including lung cancer.

DNA Hypomethylation Is One of the Epigenetic Mechanisms Involved in Salt‐Stress Priming in Soybean Seedlings

Plant, Cell &Environment, EarlyView.
ABSTRACT Salt‐stress priming enhances the tolerance of plants against subsequent exposure to a similar stress. Priming‐induced transcriptomic reprogramming is mediated by multiple epigenetic mechanisms, the best known of which is histone modifications. However, not much is known about other epigenetic responses.

Network of epistatic interactions within a yeast snoRNA [PDF]

Science, 2016
Epistasis and mutational fitness landscapeA fitness landscape of a gene defines the molecular potential of evolution. This can help us understand the current state of evolution as well as predict unrealized potential. Using deep sequencing to examine mutations in nonessential genes that affect the growth of yeast strains, two studies have generated ...
