Figure Lengend Snippet: Heat map of Phenotype MicroArray TM (PM) results for carbon and nitrogen source utilization by PAM 2766 T , R. equi DSM 20307 T and R. equi 103S (PAM 1126). Bacterial inocula were grown at 30°C in TSB until the stationary phase and then suspended in mReMM mineral medium and transferred to the PM plates. Incubabion was performed at 30°C with OD 590 monitored every 15 min for 48 hours in an OmniLog reader. Strains were tested in duplicate and results were analysed using OmniLog software. Maximum growth is represented in graded colours from lowest (black) to highest (yellow). Red arrows indicate differential utilization of a substrate between PAM 2766 T and R. equi. Black arrows in the PM1 and PM2A plates indicate a carbon source utilized by the three tested bacteria (see Table S2 for detailed results). Asterisks indicate false positive reactions in the PM2A plate previously reported in ref. .

Article Title: A white-box machine learning approach for revealing antibiotic mechanisms of action

doi: 10.1016/j.cell.2019.04.016

Figure Lengend Snippet: (A) Overall experimental design for measuring metabolite effects on antibiotic lethality. Overnight cultures of E. coli MG1655 were inoculated into MOPS minimal medium, grown to early exponential phase, and back-diluted to OD600 = 0.1. Cells were dispensed into Biolog phenotype microarray plates (PMs) 1–4 (Bochner, 2009) with different concentrations of ampicillin (AMP), ciprofloxacin (CIP) or gentamicin (GENT) added. OD600 was measured after 4 hours of incubation at 37°C and 900 rpm shaking. Antibiotic IC50s were estimated for each antibiotic-metabolite combination.

Article Title: Large-scale analysis of DNA methylation in chronic lymphocytic leukemia

doi: 10.2217/epi.09.10

Figure Lengend Snippet: This cluster is based on a 10% threshold where there are 12 samples with less than 10% of the cells expressing CD38 and 26 samples with more than 10% CD38 expression. This illustrates a measure of relatedness of DNA methylation across all loci for each sample. Each column represents a patient sample and each row represents a clone/locus on microarray chip. The florescence ratios of cy3/cy5 are measures of DNA methylation and are depicted as a color intensity (-0.5 to +0.5) in log base 2; yellow indicates loci that have a higher level of DNA methylation in chronic lymphocytic leukemia compared with normal controls, blue indicates a lower level of methylation and black indicates no change. Graded colors across the spectrum represent various levels of methylation. The dendrogram from the top of the cluster (rotated 90° and enlarged on the right) represents the CD38 expression level of each sample. Not every patient sample clustered with the expected group. The numbers shown in blue color are seven patients with CD38high that are clustered in the group of 10% or less, and one sample with 6% CD38 clustered with the CD38high group.

Figure Lengend Snippet: Plot of gene expression of sorted/unsorted cells . Plot of one-sample T-test p-values with fold-change in gene expression for all ORFs in microarray study I. Vertical lines show the cutoff of fold-change of 2 (Log 2 ratio of ± 1), while the horizontal line shows the cutoff of p-value 0.05. Genes located in the left-bottom corner (Log 2 ratio <-1 and p-value <0.05) and in the right-bottom corner (Log 2 ratio >1 and p-value <0.05) were considered to have their expressions changed due to dispersion/homogenization and IMS (immuno-magnetic separation) cell sorting. A total of ten genes were selected using these criteria, eight of which also differentially expressed in the independent microarray study II.
