OBJECTIVE Monocyte/macrophage inflammation is an important contributor to diabetes and cardiovascular disease. Studies have suggested saturated fatty acids (SFA) induce monocyte inflammation in a Toll-like receptor-4-dependent manner, but recent data suggest SFA do not directly interact with Toll-like receptor-4. The present study tests the novel hypothesis(More)
Peroxisomal ascorbate peroxidase (APX) sorts indirectly via a subdomain of the ER (peroxisomal ER) to the boundary membrane of peroxisomes in tobacco Bright Yellow 2 cells. This novel subdomain characteristically appears as fluorescent reticular/circular compartments distributed variously in the cytoplasm. Further characterizations are presented herein. A(More)
It is now recognized that cross-talk between adipocytes and adipose tissue stromal cells such as macrophages contributes to local and systemic inflammation. One factor from adipocytes that may participate in this interaction and that is frequently elevated in inflammatory conditions such as obesity, insulin resistance, and type 2 diabetes is free fatty(More)
Homologs of peroxin 16 genes (PEX16) have been identified only in Yarrowia lipolytica, humans (Homo sapiens), and Arabidopsis (Arabidopsis thaliana). The Arabidopsis gene (AtPEX16), previously reported as the SSE1 gene, codes for a predicted 42-kD membrane peroxin protein (AtPex16p). Lin et al. (Y. Lin, J.E. Cluette-Brown, H.M. Goodman [2004] Plant Physiol(More)
Previously it has been shown that the endogenous Arabidopsis peroxin, AtPEX16, coexisted at steady state in membranes of the endoplasmic reticulum (ER) and peroxisomes. Herein, an ER-to-peroxisome trafficking pathway and the requisite molecular targeting signals for mycAtPEX16 transiently expressed in Arabidopsis and tobacco BY-2 suspension cells are(More)
