Background: Prostate cancer (PC) fearfully impacts men's health. We explored the efficacy and mechanism of circular RNA circZNF609 (circZNF609) on colony formation, viability, apoptosis, migration and invasion and in PC cells. Methods: Colony formation, CCK-8, flow cytometry, migration and invasion assay were respectively used to detect the functions of circZNF609 and microRNA (miR)-186-5p on cell colony ability, viability, apoptosis, migration and invasion. circZNF609 and miR-186-5p expression were changed by cell transfection and tested by RT-qPCR. Moreover, Cleaved-Caspase-3, Cleaved-Caspase-9, matrix metalloproteinase-9 (MMP-9), Vimentin and relate-proteins of cell pathways were examined through Western blot. Results: circZNF609 was highly expressed at PC tissues. circZNF609 declined cell colony ability, viability, migration and invasion and caused apoptosis. Furthermore, circZNF609 negatively regulated miR-186-5p, miR-186-5p inhibitor could reverse impacts of circZNF609. Finally, circZNF609 restrained the YAP1 and AMPK pathways by up-regulating miR-186-5p. Conclusion: Silencing circZNF609 restrained growth, migration and invasion of PC cells by upregulating miR-186-5p via YAP1 and AMPK pathways. HIGHLIGHTS 1. circZNF609 is highly expressed in PC tissues; 2. circZNF609 restrains cell growth, migration and invasion; 3. circZNF609 exerts its function by up-regulating miR-186-5p; 4. circZNF609 exerts its function by YAP1 and AMPK signaling pathways.
Hyperoxaluria and cell injury are key factors in urolithiasis. Oxalate metabolism may be altered by renal dysfunction and therefore, impact the deposition of calcium oxalate (CaOx) crystals. We investigated the relationship of renal function, oxalate metabolism and CaOx crystal deposition in renal ischemia. One hundred male Sprague-Dawley rats were randomly divided into four groups. Hyperoxaluria model (Group A and B) was established by feeding rats with 0.75 % ethylene glycol (EG). The left renal pedicle was clamped for 30 min to establish renal ischemia Groups (B and C), while Groups A and D underwent sham operation. Then, serum and urine oxalate (Ox), creatinine (Cr) and urea nitrogen (UN) levels were evaluated by liquid chromatography mass spectrometry (LCMS) and ion mass spectrum (IMS) at days 0, 2, 4, 7, and 14. CaOx crystallization was assessed by transmission electron microscope (TEM). A temporal and significant increase of serum Cr and UN levels was observed in Groups B and C compared to values obtained for Groups A and D (P < 0.05). Ox levels in serum and urine were significantly higher in Groups A and B than in the other two groups from day 7 (P < 0.05). In addition, CaOx crystallization was observed in both Groups A and B, but Group B showed earlier and more pronounced crystal deposition in the renal tissue. Our results indicated that renal tubular injury induced by renal ischemia might not affect Ox levels but could promote CaOx crystal retention under hyperoxaluria.
These findings should be highly considered by family physicians in their practice to provide infertile couples with information related to sexual well-being, coping styles, relationship, etc.
These analyses showed that high HDAC6 expression was an independent, poor prognostic factor in patients with RCC, and HDAC6 could serve as a biomarker of RCCs prognostic and an indicator for RCC progression.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
