Abstract Cancer development and its response to therapy are regulated by inflammation, which either promotes or suppresses tumor progression, potentially displaying opposing effects on therapeutic outcomes. Chronic inflammation facilitates progression treatment resistance, whereas induction of acute inflammatory reactions often stimulates the maturation dendritic cells (DCs) antigen presentation, leading anti-tumor immune responses. In addition, multiple signaling pathways, such as nuclear...
Apolipoprotein B (apoB) is the major protein component of atherogenic lipoproteins hepatic origin. In HepG2 cells, standard cell culture model human lipoprotein metabolism, there a limited availability core lipids in endoplasmic reticulum for association with nascent apoB. Under these conditions, apoB partially translocated, interacts cytosolic Hsp70, and undergoes rapid degradation. We show that increasing expression Hsp70 cells promotes addition, polyubiquitinated its degradation both...

Presentation of a wild-type secretory protein, apolipoprotein B100 (apoB), to the cytosol for ubiquitin-proteasome proteolysis has been observed in HepG2 cells. A currently accepted model proteasomal degradation proteins is retrograde translocation substrate polypeptides from lumen endoplasmic reticulum (ER) back cytosol. In this report, we present evidence that newly synthesized apoB becomes exposed and targeted proteasomes co-translational manner. Thus, after protein translation was...
Microsomal triglyceride (TG) transfer protein (MTP) is an endoplasmic reticulum lumenal consisting of a 97-kDa subunit and disulfide isomerase. It believed that MTP delivers TG to nascent apoB molecules during the assembly lipoprotein particles in secretory pathway. Although vitro studies have established mechanism between donor acceptor membranes, action vivo remains unknown. The present were undertaken examine whether or not involves physical interaction apoB. HepG2 cells labeled with...

When lipid synthesis is limited in HepG2 cells, apoprotein B100 (apoB100) not secreted but rapidly degraded by the ubiquitin-proteasome pathway. To investigate apoB100 biosynthesis and secretion further, physical functional states of destined for either degradation or lipoprotein assembly were studied under conditions which synthesis, proteasomal activity, microsomal triglyceride transfer protein (MTP) lipid-transfer activity varied. Cells pretreated with a inhibitor (which remained cells...
Elevated triglyceride (TG) and cholesterol levels are risk factors for cardiovascular disease often associated with diabetes metabolic syndrome. Recent reports suggest that fibroblast growth factor (FGF)19 FGF21 can dramatically improve dysfunction, including hyperglycemia, hypertriglyceridemia, hypercholesterolemia. Due to their similar receptor specificities co-receptor requirements, FGF19 share many common properties have been thought be interchangeable in regulation. Here we directly...
