    Agrobacterium rhizogenes induces growth of aberrant roots with bacterial T-DNA; some roots can spontaneously regenerate into plants carrying T-DNA fragments. T-DNAs contain genes that are expressed in plants which normally lead to root growth and to...

    Stalk position effect on harmful and potentially harmful cigarette smoke constituents in Burley tobacco: a case study

    Cured leaf chemistry varies sharply according to stalk positions and variations of smoke yields of harmful and potentially harmful constituents (HPHCs) are also expected. To quantitatively assess the effects on HPHC yields, Burley leaves of the...

    Use of an EpiOralTM human tissue model for testing of substances for oral irritancy in vitro

    JAI T.S.; DELVES S.J.; FAUX S.P.; KUMARAVEL T.S.; NEILSON L.R.; MEREDITH C.
    Advanced Technologies Ltd., Cambridge, UK
    The EpiOralTM tissue model consists of normal human keratinocytes differentiated to form a multilayered tissue. The phenotype is analogous to human oral epithelium in vivo providing the opportunity for in vitro irritancy testing on human tissue....

    Human bronchial epithelial cell transcriptome: gene expression changes following acute exposure to whole cigarette smoke in vitro

    PATWARDHAN S.; MAUNDERS H.; PHILLIPS J.; CLACK A.; RICHTER A.
    Advanced Technologies Ltd., Cambridge, UK
    Cigarette smoke is a complex mixture of over 4000 constituents. Its effects on cell biology are poorly understood, partly because whole smoke exposure in vitro is technically challenging. To investigate the effects of smoke on cell signalling and...
