The rapid pace at which genomic and proteomic data is being generated necessitates the development of tools and resources for managing data that allow integration of information from disparate sources. The Human Protein Reference Database (http://www.hprd.org) is a web-based resource based on open source technologies for protein information about several(More)
DNA microarray technology has led to an explosion of oncogenomic analyses, generating a wealth of data and uncovering the complex gene expression patterns of cancer. Unfortunately, due to the lack of a unifying bioinformatic resource, the majority of these data sit stagnant and disjointed following publication, massively underutilized by the cancer research(More)
Many studies have used DNA microarrays to identify the gene expression signatures of human cancer, yet the critical features of these often unmanageably large signatures remain elusive. To address this, we developed a statistical method, comparative metaprofiling, which identifies and assesses the intersection of multiple gene expression signatures from a(More)
Elicitors play an important role in challenging the plant defense system through plant-environment interaction and thus altering the secondary metabolite production. Culture filtrates of four endophytic fungi, namely, Chaetomium globosum, Aspergillus niveoglaucus, Paecilomyces lilacinus, and Trichoderma harzianum were tested on embryogenic cell suspensions(More)
Agrobacterium tumefaciens (EHA-105 harboring pCAMBIA 1304)-mediated transgenic plant production via direct regeneration from leaf and elite somaclones generation through indirect regeneration in Stevia rebaudiana is reported. Optimum direct regeneration frequency along with highest transformation frequency was found on MS + 1 mg/l BAP + 1 mg/l NAA, while(More)
Wounding is required to be made in the walls of the green seed pod of Opium poppy prior exudation of latex. To withstand this kind of trauma plants regulate expression of some metabolites through an induced transcript level. 167 unique wound-inducible ESTs were identified by a repetitive round of cDNA subtraction after 5 hours of wounding in Papaver(More)
Five cell suspension lines of Catharanthus roseus resistant to 5-methyl tryptophan (5-MT; an analogue of tryptophan) were selected and characterized for growth, free tryptophan content and terpenoid indole alkaloid accumulation. These lines showed differential tolerance to analogue-induced growth inhibition by 30 to 70 mg/l 5-MT supplementation (LD50 = 7–15(More)
A vincamine positive hairy root clone of Vinca minor with integration of all the three- rolA, rolB and rolC genes and its subsequently raised cell suspensions were treated with culture filtrate of four endophytic fungi namely Chaetomium globosum; Aspergillus niveoglaucus; Paecilomyces lilacinus and Trichoderma harzianum. Addition of 10 % v/v T. harzianum(More)
Chalcone derivatives on estradiol framework have been synthesized. Some of the derivatives showed potent anticancer activity against some human cancer cell lines. Compounds 9 and 19 showed potent activity against MCF-7, a hormone dependent breast cancer cell line. Chalcone 7 was further modified to the corresponding indanone derivative (19) using the(More)
Vinca minor is the sole source of vincamine, an alkaloid known to be used in a variety of cerebral disorders. Three stable variant shoot lines (V10, V20 and V30) with tolerance thresholds of 10, 20 and 30 mg/l 5-methyltryptophan (5-MT; analogue of tryptophan), respectively, were selected. These lines showed twofold to threefold increase in tryptophan(More)
