Abstract Early tumor recurrence in hepatocellular carcinoma (HCC) remains a challenging area, as the mechanisms involved are not fully understood. While microvascular invasion is linked to early recurrence, established biomarkers for diagnosis and prognostication lacking. In this study, our objective was identify DNA methylation sites that can predict outcomes of liver cancer patients elucidate molecular driving HCC aggressiveness. Using methylome data from patient samples CGRC TCGA databases, we pinpointed hypermethylated CpG HCC. Our analysis revealed cg02746869 acts crucial regulatory site VIM-AS1 (vimentin antisense RNA1), 1.8 kb long noncoding RNA. RNA sequencing cells with manipulated expression EPHA3 pathogenic target , which performs an oncogenic function Hypermethylation-induced suppression significantly impacted cell dynamics, particularly impairing motility invasiveness. Mechanistically, reduced stabilized mRNA by enhancing binding IGF2BP1 mRNA, leading increased promotion progression. vivo experiments further confirmed VIM-AS1‒EPHA3 axis controlled growth microenvironment These findings suggest downregulation due hypermethylation at via m6A-dependent mechanism increase

Long non-coding RNAs (lncRNAs) have been established as pivotal players in various cellular processes, encompassing the regulation of transcription, translation and post-translational modulation proteins, thereby influencing functions. Notably, lncRNAs exert a regulatory influence on diverse biological particularly context tumor development. Tumor-associated macrophages (TAMs) exhibit M2 phenotype, exerting significant impact crucial processes such initiation, angiogenesis, metastasis immune evasion. Elevated infiltration TAMs into microenvironment (TME) is closely associated with poor prognosis cancers. LncRNAs within play direct role regulating processes. Functioning integral components tumor-derived exosomes, prompt M2-like polarization macrophages. Concurrently, reports indicate that cells contribute to expression release molecules modulate TME. These actions induce recruitment, TAMs, providing critical support for In this review, we survey recent studies elucidating macrophage function across different types

Breast cancer (BC) is a multifactorial condition and it primarily expresses the estrogen receptor α (ERα) that encoded by gene 1 (ESR1), which modulates signaling. ESR1, facilitating overproduction, plays an indispensable role in progression survival of majority BCs. To obtain molecular insights into these phenomena, we analyzed The Cancer Genome Atlas (TCGA) breast invasive carcinoma (BRCA) RNA-Seq datasets for expression ESR1 its correlation to microRNAs (miRNAs) long non-coding RNAs (lncRNAs), along with methylation patterns. Regulation was also assessed total 43 cancerous non-cancerous cell lines. Analyses both TCGA BRCA line data revealed specific lncRNAs, i.e., MEG3, BIK, MLL, FAS are negatively correlated PARP1 demonstrates positive association. Additionally, miR-30a miR-145 showed negative correlations expression. Of 54 loci analyzed, them exhibited expression, highlighting potentially modifiable regulatory mechanism. These findings underscore complex events influencing interaction diverse signaling pathways, demonstrating novel pathogenesis potential therapeutics.
