Investigation of Some Inflammation Related Gene Expressions Under Lipotoxic Endoplasmic Reticulum Stress In Mouse Macrophage Cell Line
Öz
Objectives: The accumulation of free fatty acids in non-adipose tissues lead to cellular lipotoxicity and induce endoplasmic reticulum ER stress. To restore ER homeostasis, cells evoke an adaptive mechanism that is known as the unfolded protein response UPR . The aim of this study was to investigate the potential relationship between ER stress and some inflammasome complexes under lipotoxic ER stress conditions in the mouse macrophage cell line RAW 264.7 .Materials and Methods: The mouse macrophage cells RAW 264.7 were treated with Ethanol-BSA control or Palmitate-BSA 500μM . The expression of inflammation-related target genes was investigated using the qRTPCR method. Results: A significant induction at the mRNA levels of mTNFα, mNFκBIB, mIRF7, mCCL5, and reduction at the mRNA level of mIRF1 after lipid-induced metabolic ER stress were observed in RAW 264.7 cells.Conclusion: Together, these findings confirm that UPR regulates the expression of key inflammation-related genes under saturated lipid-induced stress conditions

LİPOTOKSİK ENDOPLAZMIK STRES SONUCU İNFLAMASYON ILE İLIŞKILI BAZI GEN İFADELERININ FARE MAKROFAJ HÜCRE HATTINDA ARAŞTIRILMASI
Öz
Amaç: Adipoz olmayan dokularda serbest yağ asitlerinin birikmesi, hücresel lipotoksisiteye ve endoplazmik retikulum ER stresine neden olur. ER homeostazını geri kazanmak için hücreler, katlanmamış protein tepkisi UPR olarak bilinen bir uyarlamalı mekanizma uyandırır. Bu çalışmada, lipotoksik ER stres koşulları altında ER stres ve bazı inflamasyon kompleksleri arasındaki moleküler ilişki fare makrofaj hücre hattında RAW 264.7 araştırılmıştır. Gereç ve Yöntem: Fare makrofaj hücreleri RAW 264.7 , Ethanol-BSA kontrol veya Palmitate-BSA 500 μM ile muamele edildi. İnflamasyonla ilişkili hedef genlerin ekspresyon değişimleri qRT-PCR yöntemi kullanılarak araştırıldı. Bulgular: RAW 264.7 hücrelerinde lipit kaynaklı metabolik ER stres sonrasında; mTNFα, mNFκBIB, mIRF7, mCCL5 mRNA seviyelerinde artış ve mIRF1 mRNA seviyesinde azalma olduğunu gözlemledi. Sonuç: Bu çalışmanın sonuçları UPR’ nin, doymuş lipit kaynaklı stres koşulları altında temel inflamasyonla ilişkili genlerin ekspresyonunu düzenlediğini doğrulamaktadır.
