Abstract

Purpose: The aim of this study was to investigate the role of Ganoderma lucidum (GL) in cell proliferation and autophagy in breast cancer cell lines.
Materials and Methods: Cell lines were cultured in vitro and the appropriate dose was determined by the MTT method. In order to show the effect of GL on autophagy in MCF-7 and MDA-MB-231 breast cancer cell lines, Beclin-1, LC3 and p62 expression were examined by immunohistochemistry staining. Additionally, cell cycle analysis was carried out in GL-treated and untreated cells using a cell cycle analysis kit to look into how GL affects cell division.
Results: Viability level was significantly reduced in MCF-7 and MDA-MB-231 cells incubated with 40 and 80 μM concentrations of GL for 24 hours. In addition, GL induced the initiation of autophagy in MDA-MB-231 and MCF-7 cells, as evidenced by enhanced levels of Beclin-1, LC3 and p62 expression. At the same time, this study showed that GL induced cell cycle arrest in the G2/M phases.
Conclusion: GL has anti-proliferative activity by arresting the cell cycle at the G2/M phase and accelerates cell death by inducing autophagy, particularly in aggressive breast cancers that are resistant to treatment..

Abstract

Amaç: Bu çalışmada meme kanseri hücre dizilerinde Ganoderma lucidumun (GL) hücre proliferasyonu ve otofaji ile ilişkisinin belirlenmesi amaçlanmıştır.
Gereç ve Yöntem: Hücre hatları in vitro ortamda kültüre edildi ve uygun doz MTT yöntemi ile belirlendi. MCF-7 ve MDA-MB-231 meme kanseri hücre hatlarında GL'nin otofaji üzerindeki etkisini göstermek için, immünohistokimya boyaması ile Beclin-1, LC3 ve p62 ekspresyonu incelenmiştir. Ek olarak, GL'nin hücre bölünmesi üzerindeki etkisini araştırmak için, bir hücre döngüsü analiz kiti kullanılarak GL uygulanan ve uygulanmayan hücre döngüsü analizi yapıldı.
Bulgular: 24 saat süreyle GL'nin 40 ve 80 μM’lik konsantrasyonlarıyla inkübe edilen MCF-7 ve MDA-MB-231 hücrelerinde canlılık düzeyinin önemli ölçüde azaldığı gösterildi. Ek olarak, GL, artan Beclin-1, LC3 ve p62 ekspresyonu seviyeleri ile kanıtlandığı gibi, MCF-7 ve MDA-MB-231 hücrelerinde otofajinin başlatılmasını indüklemiştir. Aynı zamanda, bu çalışma GL'nin G2/M fazlarında hücre döngüsü durmasını indüklediğini gösterdi.
Sonuç: GL, hücre döngüsünü G2/M fazında durdurarak anti-proliferatif aktiviteye sahiptir ve özellikle tedaviye dirençli agresif meme kanserlerinde otofajiyi indükleyerek hücre ölümünü hızlandırır.
