Summary: This study revealed that hsa_circ_0030586 is significantly upregulated in prostate cancer cells and may promote epithelial-mesenchymal transition (EMT) through the PI3K-AKT signaling pathway. Experiment results showed that interfering with hsa_circ_0030586 could inhibit tumor cell proliferation, migration, and invasion in PCa.

Summary: The study found that miR-182 promotes EMT in GBC cells by targeting FOXN3, which in turn suppresses the Wnt/beta-catenin pathway. Decreased miR-182 expression led to attenuated EMT and reduced activity of beta-catenin and its downstream factors in GBC cells. Overexpression of FOXN3 improved EMT and the beta-catenin pathway.

Summary: Pancreatic ductal adenocarcinoma (PDAC) is a highly malignant tumor with poor prognosis. The molecular mechanisms of pancreatic oncogenesis and malignant progression are not fully understood. Recent studies have shown that long noncoding RNAs (lncRNAs) and circular RNAs (circRNAs) play important roles in the epithelial-mesenchymal transition (EMT) process in PDAC, affecting the migration and invasion of tumor cells. These RNAs can regulate the expression of EMT-related proteins through different mechanisms, thus influencing the development of cancer.

Summary: The newly discovered circular RNA hsa-circ_0058106 is upregulated in laryngeal cancer and is associated with lymph node metastasis and advanced clinical stages. Silencing hsa-circ_0058106 inhibits migration and invasion of laryngeal cancer cells, and suppresses epithelial-mesenchymal transition (EMT). Mechanistically, hsa-circ_0058106 sponges miR-153 to regulate Snail1 expression and blocks the nuclear translocation of Twist1.

Summary: RNA axes have been studied in breast cancer, but not used for risk assessment in early-onset breast cancer. By investigating in a breast epithelial culture model and a patient cohort, potential RNA biomarkers associated with breast cancer initiation risk were identified.

Summary: Circular RNAs are important regulatory molecules in cellular processes and may be involved in tumor growth and diffusion. The circular RNA from the DOCK1 gene shows differential expression in breast cancer cell lines with different phenotypes and influences the expression of common genes. The study provides insights into the role of specific circular RNAs in the generation and progression of breast cancer.

Summary: This paper investigates the expression and role of miR-182 in prostate cancer. The study finds that miR-182 is over-expressed in prostate cancer cells and is associated with clinical markers of disease progression. It also identifies MITF as a novel target of miR-182 in prostate cancer. The findings suggest that miR-182 could be a useful biomarker for diagnosing and predicting the prognosis of prostate cancer.

Summary: Triple negative breast cancers (TNBC) are a morphologically and genetically heterogeneous group of breast cancers with uncertain prediction of biological behavior and response to therapy. Epithelial to mesenchymal transition (EMT) is a dynamic process characterized by loss of typical epithelial phenotype and acquisition of mesenchymal characteristics. The study aimed to analyze miRNA expression within areas of TNBCs with cellular morphology related to the EMT process, and found a specific miRNA expression profile of apocrine and spindle cell morphology which may be relevant for prognosis and therapy resistance of TNBC.

Summary: In this study, an EMT-related lncRNA signature was constructed to predict the prognosis of breast cancer patients. A risk score signature consisting of 10 lncRNAs associated with the EMT process was developed and validated. The signature was also evaluated for its impact on drug sensitivity and tumor immune cell infiltration in breast cancer.

Summary: In this study, the highly expressed circRNA circ_0001789 was identified in gastric cancer tissues. Silencing circ_0001789 attenuated the malignancy of gastric cancer cells, and exosomal circ_0001789 was sufficient to regulate the malignant phenotype of gastric cancer cells. miR-140-3p was identified as a downstream target of circ_0001789, negatively correlated with circ_0001789 expression in gastric cancer tissues. Overexpression of miR-140-3p suppressed cell migration, invasion, and epithelial-mesenchymal transition in gastric cancer cells, and PAK2 was identified as the target of miR-140-3p to mediate the malignant phenotype of gastric cancer cells.

Summary: This study reveals that circPSMA1 functions as a tumor promoter in triple-negative breast cancer (TNBC) by acting as a miRNA sponge to absorb miR-637 and regulate Akt1-beta-catenin (cyclin D1) axis. Exosomes from TNBC cells carrying high levels of circPSMA1 can transmit migration and proliferation capacity to recipient cells. High expression of Akt1 and low expression of miR-637 are highly correlated with poor prognosis in TNBC patients with lymph node metastasis.
