RESUMO

BACKGROUND/AIM: The anticancer mechanism of itraconazole remains unsolved; therefore, we studied itraconazole-induced alterations in specialized pro-resolving mediators (SPMs) in cancer cells. MATERIALS AND METHODS: The human cervical squamous carcinoma cell line CaSki was cultured with or without 1 µM itraconazole. Liquid chromatography/mass spectrometry analysis was conducted to identify SPMs that were influenced by itraconazole. Cell growth experiments were conducted using itraconazole and inhibitors targeting the metabolic pathways of candidate SPMs. RESULTS: Resolvin E3, resolvin E2, prostaglandin J2 (PGJ2), delta-12-PGJ2, and maresin 2 were identified as candidate SPMs. The 12/15-lipoxygenase inhibitor, which is involved in the conversion of 18-hydroxy-eicosapentaenoic acid to resolvin E3, attenuated the inhibitory effect of itraconazole. Inhibition of the PGJ2 metabolic pathway did not interfere with itraconazole treatment. CONCLUSION: The metabolic pathway of SPMs, including resolving E3, could be proposed as an anticancer target of itraconazole.

RESUMO

Amyloidosis of the uterine cervix is rare. A 35-year-old pregnant woman underwent a cervical biopsy and was found to have amyloid deposits. The results of liquid chromatography-tandem mass spectrometry revealed that these deposits mainly consisted of immunoglobulin light chain (kappa chain). After undergoing several examinations, the patient was diagnosed with localized amyloidosis, without systemic or secondary amyloidosis. She underwent a normal delivery without disease exacerbation. The possible presence of systemic and secondary amyloidosis must be evaluated carefully during the diagnosis of localized cervical amyloidosis.
