Article Abstract
Objectives: To explore the effects of Lin28A on progression of osteocarcinoma (OS) cells.
Results: Lin28A mRNA and protein expressions were significantly increased in OS tissues compared with that in normal adjacent tissues. Expressions of Lin28A and long noncoding RNA MALAT1 were positively correlated. Patients with higher Lin28A expression had shorter overall survival. Moreover, Lin28A knockdown inhibited OS cells proliferation, migration, invasion and promoted cell apoptosis; Lin28A was found to harbor binding sites on MALAT1 sequences and associated with MALAT1, and increased MALAT1 stability and expression. Notably, the inhibition of Lin28A knockdown was attenuated or even reversed by MALAT1 overexpression.
Conclusions: RNA binding protein Lin28A could facilitate OS cells progression by associating with the long noncoding RNA MALAT1.

Metabolic associated steatohepatitis (MASH) is a severe form of metabolic dysfunction-associated steatotic liver disease (MASLD) characterized by hepatocellular injury, inflammation, and fibrosis. Despite advances in understanding its pathophysiology, the molecular mechanisms driving MASH progression remain unclear. This study investigates the role of long non-coding RNA Linc01271 in MASLD/MASH pathogenesis, ant its involvement in the miR-149-3p/RAB35 axis and PI3K/AKT/mTOR signaling pathway.

The necessity of this unique mechanism remains unsubstantiated, as does the role of recursive splicing (RS) in human disease. From analyses of rare copy number variants (CNVs) from almost one million individuals, we previously identified large, heterozygous deletions eliminating an RS site (RS1) in the first intron of that conferred substantial risk for attention deficit hyperactivity disorder (ADHD) and other neurobehavioral traits.

Long non-coding ribonucleic acids (lncRNAs) form a subclass of non-coding RNAs (ncRNAs), they are quite long and as their name non-coding suggests they do not have a role in protein coding. lncRNAs are vital in all the key steps of tumorigenesis, such as epithelial-mesenchymal transition, cancer stem cells formation, invasion, migration, and formation of the tumor vasculature. lncRNAs are classified into oncogenic or anti-tumor lncRNAs based on their functions.

Bladder cancer (BC) is a disease that predominantly affects older adults, with aging playing a critical role in its onset and progression. Age-associated phenomena, including immunosenescence and chronic inflammation, form a pro-tumor milieu, while genomic instability and epigenetic drift further increase cancer risk. The review highlights the dual role of DNA methylation in BC: global hypomethylation can activate transposable elements and oncogenes, whereas focal hypermethylation silences tumor-suppressor genes like CDKN2A, especially detrimental in older tissues that rely on these genes for senescence control.
