Research Focus

Research in this laboratory is focused on cellular stress responses originated from the endoplasmic reticulum (ER) and/or mitochondria that modulate inflammation and metabolism that are associated with metabolic disease, autoimmune disease, and cancer. The ER is an organelle that is primarily recognized as a compartment for protein folding and assembly, a pool of intracellular calcium, and a site for lipid and sterol biosynthesis. Physiological states that increase protein-folding demand, or stimuli that disrupt protein folding reactions, create an imbalance between the protein-folding load and capacity of the ER. This can cause accumulation of unfolded or misfolded proteins in the ER lumen -a condition referred to “ER stress”. To ensure the fidelity of protein folding and to handle the accumulation of unfolded or misfolded proteins, the ER has evolved a group of signal transduction pathways collectively termed “Unfolded Protein Response (UPR)” to alter transcriptional and translational programs. The UPR is a critical regulator in the initiation and progression of a variety of human diseases. Research projects in the Zhang laboratory include: 1) regulation of hepatic energy metabolism by ER stress-inducible transcriptional activators; 2) roles and mechanisms for the UPR transducer IRE1a in rheumatoid arthritis and lupus; 3) airborne particulate matter (PM2.5)-induced cellular stress responses and their effects on non-alcoholic steatohepatitis (NASH) and type-2 diabetes; and 4) roles of ER lipid-raft proteins and UPR transducers in breast cancer malignancy maintenance and therapy resistance.
