IN VITRO ANTITUMOR ACTIVITY OF PATULIN ON LİVER AND LUNG CANCER CELL LINES

Öz

Objective: Patulin is a mycotoxin produced by some molds, mainly Aspergillus and Penicillium, and is responsible for mycotoxicosis in animals and humans. Although there are still no detailed data on the antitumor activity of patulin, some reports indicate that it induces cellular apoptosis and toxicity. Our aim in this study is to determine the antiproliferative and antimigration effects of patulin on human liver and lung cancer cells and its effect on gene expressions in apoptotic pathways.

Material and Method: HEP3B and A549 cell lines were used to determine the efficacy of patulin in the treatment of liver and lung cancers. Cell lines were exposed to increasing concentrations of patulin (1, 2.5, 5, 10, 25, 50, and 100 µM), followed by determination of cell viability, cell migration, and apoptosis by MTS assay, wound healing assay, and RT-PCR assays.

Result and Discussion: Patulin caused a dose-dependent significant decrease in cell viability and cell migration in both cancer cell lines. It also promoted the induction of apoptosis in both cell lines. Our results showed that patulin can significantly reduce tumor growth in human liver and lung cancer cells in vitro.

PATULİNİN KARACİĞER VE AKCİĞER KANSERİ HÜCRE HATLARI ÜZERİNDEKİ İN VİTRO ANTİTÜMÖR AKTİVİTESİ

Öz

Amaç: Patulin, başta Aspergillus ve Penicilium olmak üzere bazı küf mantarları tarafından üretilen bir mikotoksin olup, hayvanlarda ve insanlarda mikotoksikozdan sorumludur. Patulinin antitümör aktivitesi hakkında hala çok ayrıntılı veriler bulunmamakla birlikte bazı raporlar hücresel apoptozu ve toksisiteyi indüklediğini göstermektedir. Bizim bu çalışmadaki amacımız patulinin insan karaciğer ve akciğer kanseri hücreleri üzerindeki antiproliferatif, antimigrasyon etkilerini ve apoptotik yolaklardaki gen ifadeleri üzerine etkisini belirlemektir.

Gereç ve Yöntem: Patulinin karaciğer ve akciğer kanserleri tedavisindeki etkinliğini belirlemek için HEP3B ve A549 hücre hatları kullanıldı. Hücre hatları, artan konsantrasyonlarda patuline (1, 2.5, 5, 10, 25, 50 ve 100 µM) maruz bırakıldı, ardından MTS testi, yara iyileşme testi ve RT-PCR deneyleri ile, hücre canlılığı, hücre göçü ve apoptoz belirlendi.

Sonuç ve Tartışma: Patulin her iki kanser hücre hattında da doza bağlı olarak hücre canlılığında ve hücre göçünde önemli bir azalmaya neden oldu Ayrıca her iki hücre hattında da apoptozun indüksiyonunu teşvik etti. Sonuçlarımız patulinin insan karaciğer ve akciğer kanser hücrelerinde tümör büyümesini in vitro olarak önemli ölçüde azaltabileceğini gösterdi.
