Abstract The low-density lipoprotein receptor (LDLR) plays a central role in cholesterol homeostasis. Here, we provide evidence that an increase in endoplasmic reticulum (ER) stress response or a disturbance of mitochondrial function inhibits LDLR expression in human liver Sk-Hep1 cells. Both ...

Abstract Helicobacter pylori, the etiological agent of several human gastric diseases, induces the transcription factor nuclear factor-κB (NF-κB) in colonized epithelial cells leading to the release of proinflammatory mediators. Activation of NF-κB involves the IκB kinase (IKK)-complex ...
