AI Article Synopsis
- Perfluorooctanoic acid (PFOA) is found in the blood of pregnant women and may affect fetal development through changes in DNA methylation.
- A study compared serum PFOA levels in pregnant women and analyzed offspring's DNA methylation but found no significant differences overall when accounting for various factors.
- Some CpG sites showed potential differences based on PFOA levels, suggesting the need for larger studies to better understand the implications of PFOA on health.
Article Abstract
Perfluorooctanoic acid (PFOA), a perfluoroalkyl substance, is commonly detected in the serum of pregnant women and may impact fetal development via epigenetic re-programming. In a pilot study, we explored associations between serum PFOA concentrations during pregnancy and offspring peripheral leukocyte DNA methylation at delivery in women with high (n = 22, range: 12-26ng/mL) and low (n = 22, range: 1.1-3.1ng/mL) PFOA concentrations. After adjusting for cell type, child sex, and income, we did not find differences in CpG methylation in the two exposure groups that reached epigenome-wide significance. Among the 20 CpGs with the lowest p-values we found that seven CpG sites in three genes differed by exposure status. In a confirmatory cluster analysis, these 20 CpGs clustered into two groups that perfectly identified exposure status. Future studies with larger sample sizes should confirm these findings and determine if PFOA-associated changes in DNA methylation underlie potential health effects of PFOA.

Unlabelled: Cladribine indirectly downregulates methylation of DNA, RNA, and histones by blocking the transfer of methyl groups from -adenosyl-methionine. The cladribine and rituximab combination showed a synergetic effect in treating B-cell lymphomas. Bortezomib (Velcade) is a Food and Drug Administration (FDA)-approved proteasome inhibitor for treating mantle cell lymphoma (MCL).

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.

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.
