Distribution of the control values of each HTS plate (the control values of each HTS plate were normalized over [0, 1] so that they can be displayed in the same plot). The exposure time is identified by the “-Tx” appended to a cellular response. The upper and lower boundaries of a solid bar identify the first quartile (Q1) and the third quartile (Q3) of the data, the symbol “ͼ” inside the solid bar represents the median of the data; ends of the whiskers are the smallest and largest observations within the range defined by [Q1-1.5(Q3-Q1), Q3+1.5(Q3-Q1)]. Control values outside the range are considered as outliers (marked by “○”) since they are abnormally deviated from the majorities of control populations. It is noted that only a small percent of outliers were identified in control data (1.5% and 2.8% for RAW264.7 and BEAS-2B cell lines, respectively) via the box-plots. 2 Electronic Supplementary Material (ESI) for Analyst This journal is © The Royal Society of Chemistry 2013 Figure S2.

Summary of the ten luciferase-reporter based and the four fluorescence-based cell response assays TF Pathway CRE cAMP/PKA E2F/ DP1 Cell Cycle Myc/ Max c-myc NFkB NFkB SMAD2/ SMAD3/ SMAD4 TGF-beta p53 p53/DNA Damage Significance cAMP response element is a point of convergence for many extracellular and intracellular signals, including cAMP, calcium, G-protein coupled receptors (GPCR) and neurotrophins Regulator of cell-cycle checkpoints in mammalian cells-major target of the retinoblastoma gene product (Rb) and the activity of E2F/pRb is intimately connected with the G1-S transition of the cell cycle Transcription factor that heterodimerizes with an obligatory partner, Max, and regulates the transcription of genes important for cell proliferation, differentiation, and apoptosis. Nuclear factor-kappaB plays a key role in inflammation, immune response, cell proliferation and protection against apoptosis Transforming growth factor β (TGFβ) signaling pathway is involved in many cellular processes, including cell cycle arrest, differentiation, homeostasis, and immunosuppression. TGFβ signaling induces phosphorylation and activation of the SMAD2 and SMAD3 proteins, which then form complexes with the mediator SMAD4. These SMAD complexes then translocate to the nucleus, where they activate the expression of TGFβ-responsive genes Role in DNA repair, cell cycle arrest, and apoptosis. TCR and Elk-1, form a complex with the SRF over the serum response element (SRE), and activate gene expression. The Elk-1 protein is phosphorylated by mitogen-activated protein kinase (MAPK), causing increased DNA binding, ternary complex formation, and transcriptional activation of target genes Hypoxia-inducible factor-1 protein is a key regulator of oxygen homeostasis and plays significant roles in cancer progression as well as in cardiovascular diseases Activator protein-1 (AP1) transcription factor is a hetero- or homo-dimeric complex that comprises members of the proto-oncogene Jun protein family (cJun, JunB and JunD) and Fos protein family (c-Fos, Fos B, Fra-1 and Fra-2). The stress-activated protein kinase/Jun N-terminal kinase (SAPK/JNK) signal transduction pathway is responsible for the phosphorylation and activation of Jun, which in turn activates AP1 NFAT family of transcription factors plays a role in the transcriptional regulation of cytokine genes and other genes critical for the immune response. Several pathways are associated with activation of the NFAT enhancer element, including calcineurin and protein kinase C Elk-1/ SRF MAPK/ERK HIF1A Hypoxia AP1 MAPK/JNK NFAT PKC/Ca++ Probe pathway Significance Fluo-4 Intracellular calcium Detect intracellular calcium influx.
