AI Article Synopsis

  • Researchers aim to understand Parkinson's disease (PD) pathology, noting that only about 10% of patients have identified genetic mutations, indicating it's a multifactorial disorder.
  • Recent studies highlight the role of epigenetics, such as changes in miRNA expression, histone modification, and DNA methylation, in the development of PD.
  • Analysis of methylation levels in specific PD-related genes across different brain regions revealed fluctuations that may influence gene expression through alterations in Sp1 binding.

Article Abstract

Efforts have been made to understand the pathophysiology of Parkinson's disease (PD). A significant number of studies have focused on genetics, despite the fact that the described pathogenic mutations have been observed only in around 10% of patients; this observation supports the fact that PD is a multifactorial disorder. Lately, differences in miRNA expression, histone modification, and DNA methylation levels have been described, highlighting the importance of epigenetic factors in PD etiology. Taking all this into consideration, we hypothesized that an alteration in the level of methylation in PD-related genes could be related to disease pathogenesis, possibly due to alterations in gene expression. After analysing promoter regions of five PD-related genes in three brain regions by pyrosequencing, we observed some differences in DNA methylation levels (hypo and hypermethylation) in in some CpG dinucleotides that, possibly through an alteration in Sp1 binding, could alter their expression.

Article Synopsis
  • STEAP3 is a critical protein associated with cervical cancer (CC) progression, showing strong expression in CC tissues and linked to poor patient prognosis.
  • The study employed various methods, such as immunohistochemistry and RNA sequencing, to investigate STEAP3's role, revealing that lower methylation levels of STEAP3 are connected to worse outcomes.
  • Knockdown of STEAP3 in CC cells reduced their growth and invasion abilities while enhancing drug sensitivity, suggesting STEAP3 drives cancer cell activity through the activation of the JAK/STAT3 signaling pathway.

N6-methyladenosine regulates metabolic remodeling in kidney aging through transcriptional regulator GLIS1.

BMC Biol

December 2024

Department of Orthodontics, School and Hospital of Stomatology, Liaoning Provincial Key Laboratory of Oral Diseases, China Medical University, Shenyang, 110001, China.

Background: Age-related kidney impairment, characterized by tubular epithelial cell senescence and renal fibrosis, poses a significant global public health threat. Although N6-methyladenosine (m6A) methylation is implicated in various pathological processes, its regulatory mechanism in kidney aging remains unclear.

Methods: An m6A-mRNA epitranscriptomic microarray was performed to identify genes with abnormal m6A modifications in aged human kidney tissues.

Single-cell DNA methylation measurements reveal genome-scale inter-cellular epigenetic heterogeneity, but extreme sparsity and noise challenges rigorous analysis. Previous methods to detect variably methylated regions (VMRs) have relied on predefined regions or sliding windows and report regions insensitive to heterogeneity level present in input. We present vmrseq, a statistical method that overcomes these challenges to detect VMRs with increased accuracy in synthetic benchmarks and improved feature selection in case studies.
