DIVERSITY-DISTURBANCE RELATIONSHIPS IN THE LATE ARCHAIC SOUTHWEST: IMPLICATIONS FOR FARMER-FORAGER FOODWAYS – ADDENDUM

The originally published version of this article (Sinensky and Farahani, 2018) did not include one of the online supplemental files, Supplemental Text 1. R markdown document. This file has now been added to the online supplemental material for this article.

We hear you

Last year, we came to the realization that online supplemental material had gotten out of control. In our conversations with authors and referees, we heard that the time needed to produce it and thoroughly review it was increasing at an unsustainable pace. In response, we changed our policy on supplemental material. Well, we’re still listening. And we’re hearing author frustration with seemingly endless rounds of external review at high-impact journals. We want to let you know that the editors of The Journal of Experimental Medicine have been working hard to avoid contributing to this problem.

Biological Applications of a Chimeric Probe for the Assessment of Galectin-3 Ligands

β1–6 branching of N-linked oligosaccharides has been correlated with the progression of different cancers. The leukoagglutinins of Phaseolus vulgaris (L-PHA) have been used to study this pattern of glycosylation whose biological significance is incompletely understood. The animal lectin, galectin-3, also binds to structures recognized by L-PHA. To develop a functional tool for the in situ identification of this pattern of glycosylation, human galectin-3 was fused to bacterial alkaline phosphatase (gal3/AP). Gal3/AP recognized both A and B blood group saccharides (B>A) and lactosamine derivatives. Gal3/AP recognition depended at least in part on the N-linked oligosaccharides of different glycoproteins. The presence and distribution of galectin-3 ligands were analyzed in both murine and human normal and tumor samples. Loss of apical expression of galectin-3 ligands was commonly found in carcinomas. Endothelial and inflammatory cells were enriched in galectin-3 ligands as compared with tumor cells; thus, gal3/AP is a suitable tool for studying tumor micro-environments. Comparative analysis of both gal3/AP and L-PHA binding patterns indicated that although similar, these patterns are not identical. The probe developed was useful for several immunoenzymatic assays and will allow the physiological and clinical significance of the expression pattern of galectin-3 ligands to be established.
