Clear cell renal cell carcinoma (ccRCC) is the most prevalent form of kidney cancer in adults, with rising global incidence and mortality rates. Early diagnosis is critical for improving patient outcomes. However, current diagnostic techniques often rely on expensive and complex instrumentation, which limits their accessibility. This creates an urgent need for affordable, sensitive, and user-friendly diagnostic methods. MiR-210–3p, a biomarker significantly upregulated in ccRCC, shows promise for non-invasive diagnostic applications. In this study, we innovatively developed a fluorescence-colorimetric dual-mode platform for miR-210–3p detection by utilizing a recently identified hemin aptamer with a stem-loop structure and by combining the trans -cleavage activity of the CRISPR/Cas12a system with the peroxidase-like activity of the aptamer/hemin complex. Moreover, using fluorescently labeled aptamer or its complementary sequence as cleavage substrates for CRISPR/Cas12a allows us to achieve two types of dual-mode detection: fluorescence “turn on” combined with colorimetric “turn off”, and fluorescence “turn on” combined with colorimetric “turn on”. This dual-mode detection platform combines sensitive quantification (with a detection limit for miR-210-3p of 0.95 pM) with rapid and visually interpretable on-site analysis, significantly enhancing the reliability and accuracy of test results. The platform has good scalability, as it is capable of detecting miR-210-3p and can also be extended to detect other tumor biomarkers. This versatility holds great potential for integration with big data analytics to personalize miRNA profiles, aiding in tumor staging, monitoring, and the development of treatment strategies, thereby advancing the field of precision medicine.

Ischemic skin flaps are highly susceptible to distal necrosis because of insufficient perfusion, oxidative stress, and dysregulated cell death. Here, we investigated the role of Hippo/YAP signaling in ischemic flap survival and identified its upstream regulatory mechanism. Hippo pathway inactivation, characterized by reduced MST1/2 and LATS1/2 phosphorylation and enhanced YAP nuclear localization, was preferentially associated with viable flap regions. Mechanistically, ischemia-induced HIF-1α upregulated miR-210-3p, which suppressed ephrin-A3 (EFNA3), weakened the EFNA3–YAP interaction, and promoted YAP nuclear translocation. Re-expression of EFNA3 partially reversed miR-210-3p-induced YAP activation and cytoprotection, confirming its functional involvement. Mechanistically, ischemia-induced HIF-1α increased miR-210-3p expression, which suppressed EFNA3 and facilitated YAP nuclear localization. EFNA3 re-expression partially reversed miR-210-3p-induced YAP activation, supporting its functional involvement. MiR-210-3p treatment was further associated with reduced oxidative injury, lipid peroxidation, mitochondrial dysfunction, and ferroptosis-related molecular alterations, together with improved perfusion and flap survival. In vivo, miR-210-3p improved local perfusion and flap survival. We further developed a virus-inspired biomimetic nanoparticle for miR-210-3p delivery, which achieved protective effects comparable to AAV-mediated delivery in vitro and in vivo. These findings identify the miR-210-3p–EFNA3–YAP axis as an important regulator of ischemic tissue adaptation and provide a non-viral miRNA delivery strategy for ischemic flap repair.
