Affymetrix Wheat Genome Array (wheat)
Description
The supply of soluble silicon (Si) to plants has been associated with many benefits that remain poorly explained and often contested. In this work, the effect of Si was studied on wheat plants under both control and pathogen stress (Blumeria graminis f.sp. tritici (Bgt)) conditions by conducting an exhaustive transcriptomic analysis (55,000 genes) aimed at comparing the differential response of plants under four treatments. The response to the supply of Si on control (uninfected) plants was limited to 47 genes providing little evidence of regulation of a specific metabolic process. Plants reacted to inoculation with Bgt by an up-regulation of many genes linked to stress and metabolic processes and a down-regulation of genes linked to photosynthesis. Supplying Si to inoculated plants largely prevented disease development, a phenotypic response that translated into a nearly perfect reversal of genes regulated by the effect of Bgt alone. These results suggest that Si plays a limited role on a plants metabolism in absence of stress, even in the case of a high-Si accumulating monocot such as wheat. On the other hand, the benefits of Si, in the form of biotic stress alleviation, were remarkably aligned with a counter-response to transcriptomic changes induced by the pathogen Bgt.

- Illumina HumanHT-12 V4.0 expression beadchip
Description
Thirty-eight tumors from 17 patients treated with BRAF inhibitor (n=12) or combination BRAF/MEK inhibitors (n=5) with known PD-L1 expression were analyzed. RNA expression arrays were performed on all pre-treatment (PRE, n=17), early during treatment (EDT, n=8) and progression (PROG, n=13) biopsies. HLA-A/HLA-DPB1 expression was assessed by immunohistochemistry (IHC). Gene set enrichment analysis (GSEA) of PRE, EDT and PROG melanomas revealed that transcriptome signatures indicative of immune cell activation were strongly positively correlated with PD-L1 staining. In contrast, MAPK signaling and canonical Wnt/--catenin activity were negatively associated with PD-L1 melanoma expression. The expression of PD-L1 and immune activation signatures did not simply reflect the degree or type of immune cell infiltration, and was not sufficient for tumor response to MAPK inhibition.

- Affymetrix C. elegans Genome Array (celegans)
Description
Low concentrations of the dissolved leonardite humic acid HuminFeed (HF) prolonged the lifespan and enhanced the thermal stress resistance of the model organism Caenorhabditis elegans. Furthermore growth was impaired and reproduction delayed, effects which have also been identified in other polyphenolic monomers, including tannic acid, rosmarinic acid, and caffeic acid. Moreover, a chemical modification of HF (HF-HQ), which increases its phenolic/quinonoid moieties, magnified the biological impact on C. elegans. To gain a deep insight into the molecular basis of these effects, we performed global transcriptomics on young adult (3 d) and old adult (11 d) nematodes exposed to two concentrations of HF and young adults (3 d) exposed to two concentrations of HF-HQ.
