Article Abstract
The long non-coding RNA taurine up-regulated gene 1 (TUG1) has been reported to be involved in various cancers, but its role in chondrosarcoma (CHS) remains a mystery. This research aimed to examine the function of TUG1 in CHS. We found that TUG1 expression was elevated in CHS. Functional assays demonstrated that TUG1 had a crucial role in the CHS cell progression. Mechanistically, TUG1 recruited ALYREF to maintain the stabilization of enhancer of zest homolog 2 (EZH2) mRNA and expression of H3K27me3, repressing the transcription of the tumor-suppressor gene . Additionally, exosomal TUG1 enhanced the polarization of M2 tumor-associated macrophages, which increased the proliferation and metastasis of CHS. Taken together, this study revealed the oncogenic role of TUG1 in CHS and its interactions with the downstream regulatory axis, offering novel insights into the tumorigenic mechanism of CHS.

Heydari et al. present an intriguing study examining the role of three long non-coding RNAs (lncRNAs)-H19, taurine upregulated gene 1 (TUG1), and colorectal neoplasia differentially expressed (CRNDE)-in the context of Coronavirus Disease 2019 (COVID-19), focusing on their diagnostic potential and biological significance. The authors argue that these lncRNAs play a role in inflammatory and fibrotic processes associated with COVID-19 and demonstrate their potential utility as biomarkers using machine learning-based predictive models.

Background: Pomegranate (Punica granatum L.) has been traditionally used in various cultures for its health benefits, particularly in promoting kidney health. Its rich composition of bioactive compounds, including polyphenols and flavonoids, has drawn attention for their potential protective effects against nephrotoxicity, a condition characterized by kidney damage due to various toxic agents.

Taurine upregulated 1 (TUG1), whose function is associated with tumor development, is a relatively new long non-coding RNA. TUG1 is overexpressed in multiple types of cancers. However, in head and neck squamous cell carcinoma (HNSCC), the behavior of TUG1 has not yet been completely elucidated.

Background: Breast cancer continues to be a predominant cause of female mortality globally, characterized by limited therapeutic options and substantial adverse effects. Artesunate (ART), a traditional Chinese medicine approved by the FDA for malaria treatment, has demonstrated potential anticancer properties against breast cancer. However, the underlying molecular mechanisms remain incompletely elucidated.

Liver diseases are progressive conditions driven by multiple factors, including molecular regulators such as nonprotein-coding RNAs, which orchestrate genetic and epigenetic processes across various biological levels. Long noncoding RNAs (lncRNAs), RNA molecules longer than 200 nucleotides, have been identified as key modulators in both cancerous and noncancerous liver diseases. Among them, (TUG1), one of the earliest discovered lncRNAs, has emerged as a tumor promoter in hepatocellular carcinoma.
