Circular RNA circFOXM1 triggers the tumorigenesis of non-small cell lung cancer through miR-132-3p/TMEM14A axis

Farlier studies indicated that circular RNAs(circRNAs)were found in various cancer clls,and circFOXM1 was reported to act as an oncogane in non-small cell lung cancer(NSCLC).However,the function of circFOXM1 in NSCLC remains undear.The epression lewels of genes were measured using quantative real-time polymerase chain reactions(qRT-PCR).Cell prolferation and apoptosis were determined by 3-(4,5 dimethylthiazol-2-yl)-25 dipbenyletrazolium bromide solution(MTT)and flow cytometry assay.The rdative protein expression was assed by westen blot Moreower,transwell assays were employed to examine ell migration and invasion.The targeted relationship was confirmed by dual-luciferase reporter assay.The expression of circFOXMI was up-regulated in NSCIC tissues and cell lines.The depletion of circFOXM1 decreased the prolferation,migration,invasion,and induced cell apoptosis of NSCLC cells.MicroRNA-132-3p(MiR-1323p)was idenified as a target of dircFOXMl.The expression level of miR-132-3p was decrased in NSCLC tssues and cell lines and inversely corrdated with circFOXM1 expression.Furthermore,the efects of drdOXMl down regulation on NSCLC cell progression were abolished by mR-1323p inhibitor.Transmembrane protein 14A(TMEM14A)was verifed as a target gene of miR-132-3p.The efects of circFOXM1 depletion on NSCLC cell proliferation,apoptosis,migration,and invasion were reversed by TMEMI4A overexpression.Our study demonstrated that knodkdown of circFOXM1 suppressed NSCLC progression through rqgulating miR-132-3p/TMEMI4A axis,sugesting the drFOXM/miR-132-3p/TMEM14A axis may serve as the novd target for NSCLC diagnosis and therapy.

A novel long-term intravenous combined with local treatment with human amnion-derived mesenchymal stem cells for a multidisciplinary rescued uremic calciphylaxis patient and the underlying mechanism

Calciphylaxis is a rare disease characterized histologically by microvessel calcification and microthrombosis,with high mortality and no proven therapy.Here,we reported a severe uremic calciphylaxis patient with progressive skin ischemia,large areas of painful malodorous ulcers,and mummified legs.Because of the worsening symptoms and signs refractory to conventional therapies,treatment with human amnion-derived mesenchymal stem cells(hAMSCs)was approved.Preclinical release inspections of hAMSCs,efficacy,and safety assessment,including cytokine secretory ability,immunocompetence,tumorigenicity,and genetics analysis in vitro,were introduced.We further performed acute and long-term hAMSC toxicity evaluations in C57BL/6 mice and rats,abnormal immune response tests in C57BL/6 mice,and tumorigenicity tests in neonatal Balbc-nu nude mice.After the preclinical research,the patient was treated with hAMSCs by intravenous and local intramuscular injection and external supernatant application to the ulcers.When followed up to 15 months,the blood-based markers of bone and mineral metabolism improved,with skin soft tissue regeneration and a more favorable profile of peripheral blood mononuclear cells.Skin biopsy after 1-month treatment showed vascular regeneration with mature noncalcified vessels within the dermis,and 20 months later,the re-epithelialization restored the integrity of the damaged site.No infusion or local treatment-related adverse events occurred.Thus,this novel long-term intravenous combined with local treatment with hAMSCs warrants further investigation as a potential regenerative treatment for uremic calciphylaxis due to effects of inhibiting vascular calcification,stimulating angiogenesis and myogenesis,anti-inflammatory and immune modulation,multidifferentiation,re-epithelialization,and restoration of integrity.

Percutaneous endoscopic removal of a residual foreign body at the orbital-cranial region after transorbital penetrating injury:a novel minimally invasive technique

Background: The orbit is susceptible to traumatic injuries, and surgical management of transorbital penetrating injury with foreign body retention is challenging due to the associated risks of nervous and vascular injury. Application of multiple imaging modalities is helpful for the preoperative surgical planning, and technical advances in percutaneous endoscopy would render the surgical approach even less invasive. Case presentation: We present a 60-year-old female patient with a transorbital penetrating injury (TPI) caused by a bamboo stick in her right eye. The bamboo stick was initially pulled out at the emergency room but, 1 month later, massive bleeding from her nose and mouth occurred. CT and CTA revealed a foreign body in the right orbito-cranial region and a traumatic aneurysm at the right internal carotid artery. Endovascular embolization was first delivered to treat the aneurysm, and the remains of the bamboo stick were completely removed with a percutaneous endoscope. The patient was discharged 1 week later. Conclusions: A careful preoperative examination by multiple imaging modalities, e.g., CT, MRI, and DSA are essential for the correct diagnosis and surgical planning for the patient with a TPI. We minimised the associated risks of vascular and nervous injuries during foreign body removal by sequential application of the endovascular intervention and percutaneous endoscopic technique.
