Abstract

Objective: Prostate cancer (PCa) patients suffer severe side effects of standard treatment beside the resistance to castration. PCa cells shows increased lipogenesis. Thymoquinone (TQ) inhibits cell proliferation, metastasis, and invasion. However, there was no study on the effect of TQ on the levels of NEDDL4, PLA2G7, and UCP2 lipid droplets (LD) related proteins. Hence, the study aims to investigate the impact of TQ on PLA2G7, UCP2, and NEDD4L proteins on DU145 and PC3 cell lines.
Materials and Methods: Cells were cultured and treated with TQ with a IC50 of 60 µM and 80 µM for DU145 and PC3, respectively. PLA2G7, UCP2, and NEDD4L levels were measured using the ELISA.
Results: TQ has significantly increased the level of NEDD4L (p<0.01 for DU145 and p<0.001 for PC3) and decreased the level of UCP2 proteins (p<0.05).
Conclusions: Our preliminary findings suggest that TQ may impact NEDD4L and UCP2, indicating a potential role in repressing LD. Further investigations are needed to confirm the efficacy of TQ and explore its potential utility as a therapeutic agent for PCa treatment.

Prostat Kanserinde Lipid Damlacık Oluşumu ile İlişkili PLA2G7, UCP2 ve NEDD4L Genlerinin Protein Seviyeleri Üzerine Timokinonun Etkisi

Abstract

Amaç: Prostat kanseri (PCa) hastalarına yönelik standart tedavide, kastrasyona dirençli tipin gelişmesinin yanı sıra ciddi yan etkiler de yaşanmaktadır. PCa hücrelerinin esas olarak artmış lipogenez ile karakterize olduğu bilinmektedir. Timokinonun (TQ) hücre proliferasyonunu, metastazı ve invazyonu inhibe ettiği gösterilmiştir. Ancak literatürde TQ'nun NEDDL4, PLA2G7 ve UCP2 lipit damlacığı ile ilişkili proteinlerin düzeylerine etkisine ilişkin bir çalışma bulunmamaktadır. Bu çalışmanın temel amacı, TQ'nun PLA2G7, UCP2 ve NEDD4L proteinleri üzerindeki DU145 ve PC3 hücre hatları üzerindeki etkisini araştırmaktır.
Materyal ve Metot: Hücreler çoğaldı ve DU145 ve PC3 için sırasıyla 60 μM ve 80 μM IC50 ile TQ ile tedavi edildi. İnkübasyondan sonra, PLA2G7, UCP2 ve NEDD4L seviyeleri ELISA yöntemi kullanılarak ölçüldü.
Bulgular: TQ, NEDD4L düzeyini önemli ölçüde artırmıştır (DU145 için p<0.01 ve PC3 için p<0.001). Ayrıca, TQ'nun UCP2 protein düzeyini azalttığı da gösterilmiştir (p<0.05).
Sonuç: Çalışmamızın başlangıç bulguları, TQ'nun öncelikle NEDD4L ve UCP2 üzerinde etkisi olabileceğini göstermektedir. Bu, TQ'nun LD üzerinde baskılayıcı bir etkiye sahip olabileceğini ve daha fazla araştırma ile PCa tedavisi için faydalı bir molekül olabileceğini öne sürmektedir
