Transcriptional gene silencing mutants in "Arabidopsis thaliana" and their impact on nuclear architecture and heterochromatin organization [PDF]

open access: yes, 2004
The epigenetic regulation of gene expression is defined by covalent modifications of DNA and histone tails as well as by chromatin structure and nuclear architecture.

Hypomethylation of GNA15 Promotes Pancreatic Ductal Adenocarcinoma Progression and Macrophage M2 Polarization via STAT3‐CXCL8 Axis

open access: yesAdvanced Science, EarlyView.
A schematic model summarizing GNA15's mechanism in mediating macrophage M2 polarization and Gemcitabine resistance. ABSTRACT The complexity of pancreatic ductal adenocarcinoma (PDAC) progression, coupled with the lack of effective immunotherapy, underscores the imperative to deepen our understanding of its mechanisms and identify suitable immune ...

The k-junction motif in RNA structure [PDF]

open access: yes, 2014
The k-junction is a structural motif in RNA comprising a three-way helical junction based upon kink turn (k-turn) architecture. A computer program written to examine relative helical orientation identified the three-way junction of the Arabidopsis TPP ...

UFL1‐Mediated UFMylation of ENO1 Restrains Aerobic Glycolysis and Colorectal Cancer Progression

open access: yesAdvanced Science, EarlyView.
UFMylation restrains aerobic glycolysis and colorectal cancer progression by modifying the glycolytic enzyme ENO1. Pharmacological enhancement of the UFL1–ENO1 interaction by the FDA‐approved antibiotic torezolid promotes ENO1 UFMylation, suppresses tumor metabolism, and sensitizes colorectal cancer to chemotherapy, revealing an actionable metabolic ...

m6Acomet: large-scale functional prediction of individual m6A RNA methylation sites from an RNA co-methylation network

open access: yesBMC Bioinformatics, 2019
Background Over one hundred different types of post-transcriptional RNA modifications have been identified in human. Researchers discovered that RNA modifications can regulate various biological processes, and RNA methylation, especially N6 ...

A small RNA response at DNA ends in Drosophila [PDF]

open access: yes, 2012
Small RNAs have been implicated in numerous cellular processes, including effects on chromatin structure and the repression of transposons. We describe the generation of a small RNA response at DNA ends in Drosophila that is analogous to the recently ...

AARS1‐Mediated RUNX3 K193 Lactylation Enhances the Activation and Cytotoxicity of CD8+T Cells in Smoking‐Related Emphysema

open access: yesAdvanced Science, EarlyView.
Exposure to CS causes an elevation of AARS1 levels, which increases the levels of RUNX3 lactylation at the K193 site and increases protein levels of RUNX3 through inhibition of autolysosomal degradation. Elevated RUNX3 levels promote CD8+T cell activation and augment their cytotoxicity, which induces alveolar epithelial cell death and facilitates the ...

Argonaute 4 as an Effector Protein in RNA-Directed DNA Methylation in Human Cells

open access: yesFrontiers in Genetics, 2019
DNA methylation of specific genome locations contributes to the distinct functions of multicellular organisms. DNA methylation can be governed by RNA-dependent DNA methylation (RdDM).

Fibrillarin Resists Cellular Senescence Via SIRT1‐Dependent Nicotinamide Metabolism and Its Inhibition Sensitizes Senolytic Therapy in Esophageal Squamous Cell Carcinoma

open access: yesAdvanced Science, EarlyView.
FBL directly binds to and stabilizes SIRT1 by blocking its ubiquitin‐proteasome degradation, thereby sustaining nicotinamide metabolism and redox homeostasis to counteract cellular senescence in ESCC. Genetic and pharmacological suppression of FBL sensitizes tumor cells to senolytic therapy.
