ZNF609 (Zinc Finger Protein 609)

Our findings indicate that cardiac inhibition of circ-ZNF609 protects against DOX-induced cardiotoxicity without compromising the anti-tumor efficacy of DOX in females. These results suggest that targeting circ-ZNF609 in the heart may represent a promising and viable therapeutic strategy for preventing DOX-induced cardiotoxicity.

These findings identify circZNF609 as a novel post-transcriptional regulator of EWS::FLI1 and establish its critical role in EwS pathogenesis. Our results suggest that targeting the circZNF609/miR-145-5p/EWS::FLI1 axis may offer a promising therapeutic strategy for EwS.

Mechanistically, circZNF609 was identified to function as a sponge for miR-324-5p, thereby upregulating voltage-dependent anion channel 1 (VDAC1) expression and promoting OC progression. Our findings indicate that circZNF609 promotes OC via the miR-324-5p/VDAC1 axis, contributing to the therapeutic targeting of this disease.

This is the first report of WES analysis of an HMSC, in this case associated with HPV type 35. The detected mutation in EP300 and the overexpression of MYB may serve as molecular targets for personalized therapy.

Our previous research revealed its role in reducing the chemosensitivity of bladder cancer (BCa) to cisplatin...CircZNF609 promoted immune escape and suppressed BCa immunotherapy sensitivity by regulating the newly identified circZNF609/IGF2BP2/CD36 cascade. Therefore, circZNF609 holds potential as both a biomarker and therapeutic target in BCa immunotherapy.

These findings may open a new window for researchers to better understand the potential pathways involved in GBM pathogenesis. In conclusion, it may provide a new potential pathway for the development of effective drugs for the treatment of GBM patients.

Exosomal Circ-ZNF609 also interacted with HuR and inhibited HuR binding to ZO-1, Claudin-1, and Occludin mRNAs, thereby reducing their translation. Collectively, our findings identified an essential function for exosomal Circ-ZNF609 from ESCC cells, suggesting the potential therapeutic value of exosomes for ESCC patients.

Moreover, it showed that circAFF1 upregulation occurs in a subset of cases with HOXA KMT2A::AFF1 ALL. Collectively, functional analyses and patient data reveal oncogenic circRNA upregulation as a relevant mechanism that sustains the malignant cell phenotype in KMT2A::AFF1 ALL.

Here, we used RNA-sequencing to investigate the effects of U2AF1 mutations on circRNA expression in K562 cells with a doxycycline-inducible U2AF1 mutation, in a mouse model with a doxycycline-inducible U2AF1 mutation, and in FACS-sorted CD34+ bone marrow cells from MDS patients with either U2AF1 or U2AF1 mutations...Several well-described cancer-associated circRNAs, including circZNF609 and circCSNK1G3, were upregulated in MDS patients with U2AF1 mutations compared to U2AF1-wildtype MDS controls. In conclusion, high circRNA expression is observed in association with U2AF1 mutations in three biological systems, presenting an interesting possibility for biomarker and therapeutic investigation.

Being aberrantly upregulated in various diseases, it could promote malignant progression of human tumors, as well as tumor cell proliferation, migration, and invasion. Here in this review, we concluded the biological functions and potential mechanisms of circ-ZNF609 in multiple diseases, which could be further explored as a targetable molecule in future accurate diagnosis and prognosis.
