Taken together, MNX1-AS1 functions as a sponge to miR-218-5p to modulate RAB1A expression in bladder cancer, which suggests that MNX1-AS1 might serve as a novel therapeutic target and a novel biomarker for metastasis and prognosis in bladder cancer.
In this review, we discuss the formation, classification, and biological functions of circRNAs, especially their molecular diagnostic values in common cancers, including gastric cancer (hsa_circ_002059, circ_LARP4, hsa_circ_0000190, hsa_circ_0000096, circ-SFMBT2, and circ_PVT1), hepatocellular carcinoma (circ_104075, circRNA_100338, circ_MTO1, and circZKSCAN1), colorectal cancer (hsa_circ_0136666 and hsa_circ_0000523), lung cancer (hsa_circ_0006427, circ_100876, and circ_ABCB10), breast cancer (hsa_circ_0089105, circAGFG1, and circEPSTI1), bladder cancer (circFNDC3B and circTFRC), and esophageal squamous cell carcinoma (circ_100876 and circ-DLG1).
In conclusion, the present study revealed that HCG22 inhibited BCa progression via the HuR/PTBP1 axis, opening new prospects for potent therapeutic regimens for BCa patients.
Our findings support that PNO1 participates in promoting proliferation and colonogenesis, while reducing apoptosis of UBC cells, and is also predicted to be associated with the migration and metastasis of UBCPNO1 knockdown (KD) attenuated the tumorigenesis ability of UBC in mouse.
The significance of actin-related protein 2/3 complex subunit 4 (ARPC4) expression in bladder cancer, and its potential role in the invasion and migration of bladder cancer cells, has yet to be determined.
Seventy-five bladder cancer cases (including 57 NMIUCs) were classified according to the quantitatively assessed degree of UroVysion-detected chromosomal abnormalities into urine fluorescence in situ hybridization score (UFS) groups: UFS I, II, and III.
These findings suggest that elevated expression of STX1A and VAMP2 might have caused the abnormal progression and invasion of cancer cells leading to the transformation of cells into high-grade tumor in bladder cancer.
Further, results from liquid chromatography-mass spectrometry (LC-MS) showed that the co-factors of AR in PCa and BCa are NFIX and HDAC2, respectively.
Androgen receptor suppresses prostate cancer metastasis but promotes bladder cancer metastasis via differentially altering miRNA525-5p/SLPI-mediated vasculogenic mimicry formation.
To identify direct downstream targets of ZFP36L1, systematic screening using RNA pull-down of wildtype and mutant ZFP36L1 as well as whole transcriptome sequencing of bladder cancer cells ± tet-on ZFP36L1, was performed.
Mechanistically, LNMAT2 was loaded to BCa cell-secreted exosomes by directly interacting with heterogeneous nuclear ribonucleoprotein A2B1 (hnRNPA2B1).
These findings suggest that elevated expression of STX1A and VAMP2 might have caused the abnormal progression and invasion of cancer cells leading to the transformation of cells into high-grade tumor in bladder cancer.
Emerging as crucial biomarkers, long noncoding RNAs (lncRNAs) play an important role in the regulation of many cancers. lncRNA NNT-AS1 has been studied in a series of cancers, whereas its role and potential molecular mechanism was poorly understood in BC.
Collectively, our findings indicate that circ0001361 plays oncogenic role in BC invasion and metastasis through targeting the miR-491-5p/MMP9 axis, and it might be a potential novel target for BC therapy.
Mechanistically, we demonstrated that circVANGL1 upregulated the expression of miR-1184 target gene insulin-like growth factor-binding protein 2 (IGFBP2) by sponging miR-1184, which promoted the aggressive biological behaviors of BC.
Mechanism dissection showed that the AR could differentially alter the expression of the VM marker SLPI through miR-525-5p to regulate SLPI; moreover, it could either increase miR-525-5p transcription in PCa or decrease it in BCa via binding to different androgen-response-elements (AREs) located at different positions in the miR-525 precursor promoter.
