MIR653 (MicroRNA 653)

The identified miRNAs exhibit strong regulatory interactions with these hub genes, while serine/threonine protein kinases emerged as the most significantly associated group. Together, these findings highlight promising biomarker candidates and potential therapeutic targets for gynecological cancers.

Drug sensitivity analysis showed that the risk score was significantly correlated with the sensitivity to various chemotherapeutic drugs (e.g., Methotrexate, Paclitaxel). This study established a reliable prognostic risk scoring model for HCC by screening differentially expressed glycolysis-related miRNAs, which effectively distinguishes between high-risk and low-risk patients and predicts patient survival. Additionally, the model is closely associated with the immune microenvironment and drug sensitivity, offering strong support for personalized treatment and clinical decision-making in HCC.

Thus, significant metabolomic imbalance in the urine was observed in the OC patients and was associated with changes in the levels of microRNAs that regulate the signaling pathways of the metabolites. The 26 compounds with abnormal concentrations and the levels of the microRNAs miR-33b-5p, miR-423-5p, miR-6843-3p, miR-4668-3p, miR-30c-5p, miR-6743-5p, miR-4742-5p, miR-1207-5p, and miR-17-5p in the urine were considered to be suitable as noninvasive diagnostic markers of OC.

This discovery highlights the significance of circWDR78 as a potential regulatory axis of miR-653-3p/RGS4 in CRC progression.

Moreover, in vivo experiments demonstrated that silencing circ_0114866 resulted in a repression of tumor growth. Our findings indicate that circ_0114866 knockdown upregulated MYL6B transcription by sponging miR-653-5p, leading to hinder the progression and EMT process of NSCLC.

Overexpression of SLC6A15 reversed the suppressive effects of DGUOK-AS1 knockdown on LUSC cell processes. In conclusion, DGUOK-AS1 promotes malignant behaviors of LUSC cells by upregulating SLC6A15 level through interaction with miR-653-5p.

On the other hand, circPOFUT1 promoted stemness and chemoresistance of CRC cells via stabilizing BMI1 in an IGF2BP1-dependent manner. In conclusion, circPOFUT1 fosters CRC metastasis and chemoresistance via decoying miR-653-5p/E2F7/WDR66 axis and stabilizing BMI1.

The functions of microRNAs were enriched in cell cycle. We identified hub messenger RNAs and core microRNAs and established a novel messenger RNA-microRNA network associated with the prognosis of prostate adenocarcinoma.

The ring structure of circAGFG1 was analyzed by RNase R and actinomycin D treatment...Knockdown of circAGFG1 inhibited tumor growth in vivo. Taken together, these data suggest that circAGFG1 acts as a sponge for miR-653-5p to mediate YWHAE expression to promote the malignant behaviors of BC.

miR-653 plays as a tumour suppressor in CRC progression, and serum exosomal hsa-circ-0004771 may be a predictive biomarker for 5-FU-resistance in CRC patients, potentially through miR-653/ZEB2 axis.

Our findings highlight the exceptional diagnostic performance of the miRNA signature as a stratifying biomarker for distinguishing between AC and SCC subtypes in lung cancer. The developed molecular diagnostic model holds promise for providing a more accurate and comprehensive molecular characterization of NSCLC, thereby guiding personalized treatment decisions and improving clinical management and prognosis for patients.

Additionally, our evidence showed that miR-653-3p promoted CRC cell proliferation, migration, and 5-FU resistance, and miR-653-3p induced the development of CRC in the xenograft mice model. Altogether, our evidence suggests that miR-653-3p regulates SIRT1/TWIST1 signaling pathway and plays an important role in promoting genomic instability, proliferation, migration, and chemoresistance of CRC cells, which may serve as a promising therapeutic target for CRC therapy.
