More and more evidence indicates that long non-coding RNAs (lncRNAs), as a kind of non-coding endogenous single-stranded RNA, play an essential role as oncogenes or tumour suppressors in the occurrence and development of human cancers. The tumour protein P73 antisense RNA 1 (TP73-AS1) was initially found to be down-regulated in oligodendroglioma and may act as a non-protein-encoding RNA. Since its discovery, TP73-AS1 has been identified as a carcinogenic regulator of many malignancies. At the same time, the high expression of TP73-AS1 is related to the clinicopathological features of patients with cancer. It also regulates cell proliferation, anti-apoptosis, invasion and metastasis through a variety of potential mechanisms, suggesting that it may be a promising biomarker and therapeutic target for cancer. In this review, we summarize the biological functions, mechanisms, and potential clinical implications of TP73-AS1 dysregulation in tumourigenesis and progression.

Insulin-like growth factor II mRNA-binding proteins (IGF2BPs), a family of RNA-binding proteins, are pivotal in regulating RNA dynamics, encompassing processes such as localization, metabolism, stability, and translation through the formation of ribonucleoprotein complexes. First identified in 1999 for their affinity to insulin-like growth factor II mRNA, IGF2BPs have been implicated in promoting tumor malignancy behaviors, including proliferation, metastasis, and the maintenance of stemness, which are associated with unfavorable outcomes in various cancers. Additionally, non-coding RNAs (ncRNAs), particularly long non-coding RNAs, circular RNAs, and microRNAs, play critical roles in cancer progression through intricate protein-RNA interactions.

Long non-coding RNAs (lncRNAs) play crucial roles in numerous biological processes and are involved in complex human diseases through interactions with proteins. Accurate identification of lncRNA-protein interactions (LPI) can help elucidate the functional mechanisms of lncRNAs and provide scientific insights into the molecular mechanisms underlying related diseases. While many sequence-based methods have been developed to predict LPIs, efficiently extracting and effectively integrating potential feature information that reflects functional attributes from lncRNA and protein sequences remains a significant challenge.

Long non-coding RNA TMC3-AS1 is identified to be upregulated by lipopolysaccharide (LPS) in inflammatory disease, but its role in acute kidney injury (AKI) is almost unknown. The study investigated the involvement of TMC3-AS1 in LPS-induced AKI and its downstream molecular regulatory mechanism. Our data suggested that knocking down TMC3-AS1 significantly reduced renal dysfunction, tissue inflammation and tissue damage in LPS-induced mice, and promoted cell viability, inhibited inflammation, apoptosis and necrosis in LPS-stimulated human renal tubular epithelial cells HK2.

RNA modifications are widespread throughout the mammalian transcriptome and play pivotal roles in regulating various cellular processes. These modifications are strongly linked to the development of many cancers. One of the most prevalent forms of RNA modifications in humans is adenosine-to-inosine (A-to-I) editing, catalyzed by the enzyme adenosine deaminase acting on RNA (ADAR) in double-stranded RNA (dsRNA).
