It is inhibited or enhanced, respectively, by Adrx knockdown and over expression Figure 2D. Moreover, and like cultured fat murine cells Figure 2BsiRNA mediated knockdown of Adrx in primary human adipocyte cultures inhibited the secretion of all adiponectin oligomers Supplemental Figure 1. Thus, these aspects of Adrx biochemistry in vitro appeared identical in mouse and human Aquarius Std S20 Q77 cells. If the overall effect of Adrx expression levels results in altered assembly of mature proteins, hence altered secretion, we would expect that cell-associated adiponectin would be enhanced by its knockdown and decreased by its over expression and this is exactly what we observe Figure 2A. In addition, the insulin receptor which has numerous intra- and intermolecular disulfide bonds [39] also shows altered expression due to Adrx manipulation, as expected, less receptor in the knockdown and more Aquarius Std S20 Q77 the over expressers Figure 2E.

In this case, it was the steady state levels of an integral membrane protein that were being altered. As shown in Figure 3A, control cells exhibited a mixture of oxidized and reduced PDI and Adrx, and cells treated with the strong oxidizing reagent diamide [41] showed fully oxidized proteins and cells treated with the reducing agent, dithiothreitol DTTshowed reduced mobility due to PEGylation. Knocking down Adrx decreased the oxidized form of PDIa1 in the basal state and in response to all doses of hydrogen peroxide Figure 3B. Overexpression of Adrx caused a slight but statistically insignificant increase in the oxidized forms of PDIa1 Figure 3C consistent with the enhanced secretion under these conditions.


Overall, we were able to identify ca. Principal component analysis Figure 4A Aquarius Std S20 Q77 the proteomic data shows good agreement between the biological replicates, and we observed that the majority of the proteome was unaffected by Adrx expression.

Figure 4B shows a heat map of all proteins quantified and Gene ontology GO enrichment analysis Aquarius Std S20 Q77 proteins in the overexpressing cells showed a significant increase in cell associated oxidoreductase and thioredoxin-related proteins and decreases in secreted adiponectin and collagen Figure 4Cthe latter two as would be expected from the data of Figure 2. Thus the amount of cell-associated, disulfide-bonded adipokines, adiponectin Adpn and resistin Rtn [44, 45] was less than in controls in the Adrx overexpressing cells and increased cell retention in the Adrx knockdown cells. On the other hand, serum amyloid A3 protein, which lacks S-S bonds [46], does not change as a result of altered Adrx expression Figure 4C.

The expression of the three specific collagen chains indicated in Figure 4C see also Supplemental Tables S1 and S2 Aquarius Std S20 Q77 affected by alterations in Adrx levels in a manner similar to adiponectin in confirmation of the biochemical analysis of Figure 2D.

Adrx null mice show decreased adipokine secretion, have mild ER stress and are hyperinsulinemic. In order to obtain data for the effects of Adrx levels in vivo, we introduced into mice Aquarius Std S20 Q77 cells obtained from KOMP for a gene construct that deletes exonsand we generated Adrx knockout mice. Mass Aquarius Std S20 Q77 analysis of intact epididymal fat tissue from WT and Adrx knockout mice confirmed that adiponectin and other adipokines show higher cellular levels enhanced retention implying reduced secretion in the knockout as compared to WT Supplemental Table S2The WT and null mice are the same weight Figure 5D and body composition Figure S3B, S3Cand the nulls have decreased levels of circulating HMW adiponectin 5E as was expected from the in vitro data Figure 2 and 3.

The knockout mice have normal blood glucose 5F are mildly hyperinsulinemic 5Gbut have normal glucose tolerance 5H. Adrx null mice are protected from fibrosis due to decreased collagen deposition. Biochemical analysis of total collagen confirmed the Aquarius Std S20 Q77 spectrometry data Figure 5J.


Thus the in vivo collagen expression data are consistent with the adipose tissue staining Figure 5I and the results from the in vitro mass spectrometry analysis and quantification Figure 2C and 4C. Interestingly, at age months, the Adrx null mice are the same weight and body composition as wild type mice, have identical glucose tolerance but have significantly higher fasting insulin Supplemental Figure Aquarius Std S20 Q77. Adrx is expressed in human adipocytes and down regulated in proportion to the level of inflammation. In addition, tissue Adrx protein levels were inversely related to the ratio of pJNK to total JNK protein for fat cells of both sexes Figure 6CpJNK being a marker of inflammation in human adipose tissue [48], and this association was independent of BMI in multiple regression models data not shown.

Lastly, male wild type mice fed a high fat diet showed elevated adipose inflammation [49] and also Aquarius Std S20 Q77 reduced Adrx levels and reduced circulating adiponectin, whereas females do not show any changes in these parameters Supplemental Figure S4. We describe herein the actions of adiporedoxin Adrxa novel protein highly enriched in adipocytes and localized to the endoplasmic reticulum, whose altered expression in vitro in mouse and human cells, and in vivo in mice, results in significant changes in adipocyte protein secretion. In particular, its knockdown in mouse and human fat cells resulted in a significant attenuation of adiponectin secretion Figures 2, 4 and S1a protein whose expression has been linked with insulin sensitivity [50] and the secretion of collagens Figure 2, 4, 5 and Supp.

Table 2proteins which can cause adipocyte fibrosis and insulin resistance [19, 51]. Both types of proteins require disulfide bonds for assembly and secretion. Moreover, we showed by proteomic analysis that Adrx over and under expression enhanced and attenuated, respectively, the secretion of several S-S bonded adipokines including resistin Figure 4 and adipsin Western blot not shown as well as affected insulin receptor amounts Figure 2the latter presumably due to its large number of disulfide linkages [39]. As most secreted proteins have disulfide bonds, appropriate controls are scarce for the measuring the effects of Adrx on secreted proteins lacking disulfides. However, serum amyloid A protein is such a protein [46], and its secretion is in fact unchanged in by manipulation of Adrx expression Figure 4. Importantly, we confirmed much of the protein secretion data in studies of Adrx null mice Figure 5which circulate lower levels of HMW adiponectin and are remarkably free of fibrosis due to impaired collagen secretion.

Lastly, Adrx protein levels in human fat tissue correlate well with adiponectin protein levels, and inversely with cellular inflammatory markers regardless of BMI.

Thus higher levels of Adrx contribute to the maintenance of healthy adipose tissue despite obesity Figure 6. The data we obtained are consistent with Adrx acting at an Aquarius Std S20 Q77 step in the secretory pathway of adipocytes. Thus reduced Adrx expression in the context of ER oxidative stress hydrogen peroxide, Figure 3 results in impaired redox regulation of PDIa1, the most abundant adipocyte chaperone found in our proteomic analysis of mouse adipose tissue Supp. Table 2which is directly involved in disulfide bond formation [21]. Adrx appears to be in the peroxiredoxin Prx family of redox-regulated proteins [52] that have diverse biological functions in a variety of cell types, reduction of peroxides being their eponymous activity [53].

The only other endoplasmic reticulum localized peroxiredoxin, Prdx4, functions in the formation of disulfide bonds indirectly, probably by regulating the amount of reactive oxygen species, principally hydrogen peroxide [54, 55]. As noted, disulfide bond formation is directly mediated by protein disulfide isomerases PDIs whose active sites have two or three -CGHC- sequences along with a chaperone fold consisting of about amino acids with four beta sheets and 3 alpha helices [21]. The PDIs bind to substrates, form and if necessary, reform and correct their disulfide bonds, although many details of the process remain unclear [34].

Moreover, unlike most members of the PDI family and Prdx4, which are soluble in the lumen of the organelle, Adrx is a transmembrane protein Figure 1 similar to the transmembrane thioredoxin-like protein 4 TMX4 only with respect to its ER membrane location [40, 56]. Based on the data of Figure 3, we hypothesize that Adrx has a function unique to adipocytes that likely involves its ability to deal with metabolically related ER oxidative stress and to mediate protein secretion under these conditions. On the other hand, the biochemical phenotype of the Adrx null mouse with regard to collagen secretion is particularly robust. Thus, considerable additional work will be required to define the biochemical role of Adrx more precisely and its hierarchical role in adipocyte ER redox regulation, and this is in progress.

Adrx has previously been reported in one publication naming it peroxiredoxin 2-like protein expressed in bone marrow monocytes PAMM, also known as Fama [52] that affects cellular redox status, a result consistent with the present data.
