CpG Island Hypermethylation in Human Astrocytomas [PDF]

Cancer Research, 2010
Abstract Astrocytomas are common and lethal human brain tumors. We have analyzed the methylation status of over 28,000 CpG islands and 18,000 promoters in normal human brain and in astrocytomas of various grades using the methylated CpG island recovery assay.

Ahcy Acts as an Effector of Hnf4a‐Driven Super‐Enhancer Activation to Alleviate MASLD During Intermittent Fasting

Advanced Science, EarlyView.
Our study identifies an Hnf4a‐driven super‐enhancer of hepatic Ahcy that mediates the protective effects of intermittent fasting against MASLD. Disruption of the Ahcy super‐enhancer reduces Ahcy expression and exacerbates lipid accumulation. This pathway prevents aberrant promoter hypermethylation by maintaining the SAM/SAH balance, as exemplified by ...

Maternal Exercise Rescues Embryonic Osteogenesis Impaired due to POLG Mutation Through a Potential Apelin‐ATF4 Axis

Advanced Science, EarlyView.
Maternal exercise (ME) increases apelin abundance across maternal and fetal tissues and is associated with improved fetal osteogenesis under POLG mutation‐induced mitochondrial dysfunction. Apelin‐APJ signaling is linked to enhanced mitochondrial function, Akt phosphorylation, and ATF4‐RUNX2 association, supporting coordinated fetal bone remodeling ...

CpG Islands Detector: a Window-based CpG Island Search Tool [PDF]

Genomics & Informatics, 2010
Abstract CpG is the pair of nucleotides C and G, appearing suc-cessively, in this order, along one DNA strand. It is known that due to biochemical considerations CpG is relatively rare in most DNA sequences. However, in par-ticular subsequences, which are a few hundred to a few thousand nucleotides long, the couple CpG is more frequent.

WTAP Transcriptional Suppression by KLF9 Drives Osteoclastogenesis via M6A‐Mediated Regulation of CSF1R Signaling in Estrogen‐Deficient Osteoporosis

Advanced Science, EarlyView.
Scheme of the KLF9/WTAP/YTHDF2/m6A/CSF1R regulatory axis in osteoclastogenesis and estrogen‐deficient osteoporosis. WTAP‐mediated m6A modification of Csf1r mRNA governs osteoclastogenesis via a YTHDF2‐mediated pathway. Pathological upregulation of KLF9 drives Wtap transcription, leading to increased m6A deposition on the 3’‐UTR of Csf1r mRNA.

A Toll for lupus [PDF]

, 2005
Toll-like receptor (TLR)-9 recognizes CpG motifs in microbial DNA. TLR9 signalling stimulates innate antimicrobial immunity and modulates adaptive immune responses including autoimmunity against chromatin, e.g., in systemic lupus erythematosus (SLE ...

Genome-scale computational analysis of DNA curvature and repeats in Arabidopsis and rice uncovers plant-specific genomic properties

BMC Genomics, 2011
Background Due to its overarching role in genome function, sequence-dependent DNA curvature continues to attract great attention. The DNA double helix is not a rigid cylinder, but presents both curvature and flexibility in different regions, depending on

ZBTB18 Dysfunction Promotes Neuropathic Pain via CHD4‐based Epigenetic Disinhibition of CLIC1 Channels in Sensory Neurons

Advanced Science, EarlyView.
In this study, we identify a novel functional role of ZBTB18 in regulating trigeminal‐mediated neuropathic pain. Nerve injury reduces ZBTB18 in trigeminal ganglion neurons, impairing CHD4/NuRD recruitment and de‐repressing Clic1. Elevated CLIC1 enhances chloride channel activity and neuronal hyperexcitability, thereby driving pain.

An Engineered HR1‐Stem Helix‐HR2 Trimeric Platform for Developing Broad‐Spectrum Coronavirus Vaccines

Advanced Science, EarlyView.
Sun et al. report a self‐assembling trimeric subunit vaccine platform termed RHS, which integrates the JN.1 receptor‐binding domain (RBD) with the heptad repeat 1 (HR1), stem helix (SH), and heptad repeat 2 (HR2) regions. The SARS‐CoV‐2 RHS vaccine elicits variant‐reactive RBD‐specific antibodies and cross‐reactive SH‐specific antibodies against ...

Epigenetics as a mechanism driving polygenic clinical drug resistance [PDF]

, 2006
Aberrant methylation of CpG islands located at or near gene promoters is associated with inactivation of gene expression during tumour development.
