The miRNA-mRNA interactions were validated using real-time PCR in independent patient cohorts. This study revealed a complex molecular landscape of mCLM within the hepatic microenvironment and novel miRNA-mRNA interactions with potential prognostic and therapeutic implications.

Combination approaches, such as pairing miR-122 mimics with miR-221 inhibitors or delivering miR-326 via nanoparticles, further enhance efficacy by simultaneously targeting multiple oncogenic pathways. This review summarizes recent advances in miRNA-mediated regulation of HCC signaling and highlights their clinical potential, including ongoing trials of miRNA-based diagnostics and therapeutics for early detection, prognostication, and personalized treatment.

Additionally, this research examines the efficacy of Regorafenib and 3,3'-diindolylmethane (DIM) as therapeutic agents aimed at mitigating the oncogenic activities of these miRNAs by influencing their structural and conformational dynamics, thereby offering a preventive strategy against CRC...They indicated a high affinity to miRNA-629-5p compared with miRNA-660-5p created a slight change in its structure and can suppress its activity in CRC. However, extra experimental approaches are needed to approve our hypothesis.

This study underscores the critical role of TPX2 in type 2 pRCC progression and highlights its potential as a prognostic biomarker and therapeutic target. The TPX2/LINC00894/miR-660-5p regulatory axis provides novel insights into the molecular mechanisms driving pRCC and offers a promising avenue for improving patient prognosis.

It also plays a role in resistance to chemotherapies like cisplatin, gemcitabine, and sorafenib in lung adenocarcinoma (LUAD), pancreatic ductal adenocarcinoma (PDAC), and hepatocellular carcinoma (HCC), thus highlighting its clinical importance. Our comprehensive study not only elucidates the aberrant expression patterns, biological functions, and regulatory networks of miR-660 and its ceRNAs but also delves into the intricate signaling pathways implicated. We envisage that our findings will furnish a robust framework and serve as a seminal reference for future investigations of miR-660, fostering advancements in cancer research and potentially catalyzing breakthroughs in cancer diagnosis and treatment paradigms.

Multiple Myeloma (MM) is the second most common hematologic malignancy, which exhibits strong resistance to bortezomib, the first-line treatment...These molecular interactions expand our understanding of the mechanisms of drug resistance in multiple myeloma. This study identified the role of hsa_circ_0058191 in the development of drug resistance in MM, which provides a theoretical foundation for designing potential therapeutic strategies to prevent drug resistance.

Adipocyte-derived exosomal miR-660-5p is a potential biomarker for evaluating radiotherapy efficacy in ESCC.

Our study highlights the upregulation and involvement of miR-660-5p in breast cancer cell proliferation, migration, invasion, and angiogenesis. Additionally, we identified TMEM41B as a direct target of miR-660-5p in breast cancer cells.

We conclude that autophagy events are more active in HCC tissues compared to the adjacent non-cancer tissues. We also reported the possible role of several miRNAs in regulating autophagy-related genes in the autophagy pathway in HCC. This may contribute to the development of potential therapeutic targets for improving HCC therapy. Future investigations are warranted to validate the target genes reported in this study using a larger sample size and more targeted molecular technique.

Intriguingly, in vitro experiments confirmed that RAMP2-AS1 was a hypoxia-suppressed lncRNA and miR-660-5p/ATM was a potential downstream axis of RAMP2-AS1 in breast cancer. Collectively, our current data elucidated a key hypoxia-suppressed lncRNA RAMP2-AS1 and its possible miRNA-mRNA regulatory mechanism in breast cancer.

Our findings unveil a previously uncharted mechanism underpinning cisplatin resistance and advocate the potential therapeutic targeting of circ_104797 in cisplatin-administered patients with BCa, offering a promising avenue for advanced BCa management.

The review concludes by highlighting exosomal ncRNAs like miR-4443 and miR-660-5p as promising therapeutic targets, offering avenues for precise cancer interventions by modulating signaling pathways and sensitizing cells to ferroptosis.
