This book presents development of an in vitro human cells based test system that is suitable for pre-clinical studies of drugs and assessment of adverse effects of various chemical compounds. As a consequence results of toxicological studies in animals can lead to false conclusions and termination of development of drug candidates potentially beneficial to humans and also to continued development of drug candidates that later show to be toxic to humans. Traditionally preclinical toxicological studies are performed on animals. The system is based on rotary vessels that simulate growth in microgravity conditions allowing the cells to grow continuously for months and create cell conglomerates that resemble normal liver tissue. Testing of drugs can be performed for hours or weeks/months to follow acute or chronic toxicity respectively. Pharmaceutical and, to a lesser degree, most other consumer products are routinely tested for safety. Metabolism of drugs and toxic compounds in many cases is different in test animals and humans.

|Isolation and characterization of novel genes from tomato. Molecular Cloning of genes associated with lycopene biosynthesis and Disease resistance in tomato Книга по Требованию Hemaprabha E. |
Hence partial cDNA coding for a key enzyme in lycopene biosynthesis, phytoene desaturase (PDS) was isolated by RT-PCR from L. pimpinellifolium. Artificial screening of tomato wild species and cultivars for resistance to Tospovirus, Fusarium and Root knot nematode revealed that L. peruvianum was resistant to all. cDNAs of three R genes coding for Tospovirus, Fusarium and Root knot nematode resistance were isolated from the wild species, L. peruvianum. A cDNA of R gene involved in Fusarium resistance was isolated from L. pimpinellifolium. Sequence analysis using bioinformatics tools viz, LALIGN, BALST, BLASTp, ClustalW, Treetop, ScanProsite of all the four cDNAs isolated corresponding to the different R genes showed considerable homology with already available disease / nematode resistance genes.
