pulmonary epithelial cell types. Additionally, by RNA microarray-analysis of laser-microdissected intrapulmonary epithelium we identified 218 potential target genes which were affected either by loss of-Dll1, or after Notch-inhibition, or under both conditions. These genes are currently being evaluated in silico as well as by expression analysis in wildtype and Notch signaling mutant embryos.
The gene encoding cystatin E/M, CST6, is a Class II tumor suppressor. Using bioinformatics tools for database mining and virtual gene expression profiling, the authors showed that CST6 is differentially expressed in various types of cancer. Moreover, epigenetic silencing mediated by hypermethylation of the CpG island located at the CST6 promoter was found to be conserved in mammalian species. C...
Quorum sensing controls the luminescence of Vibrio fischeri through the transcriptional activator LuxR and the specific autoinducer signal produced by luxI. Amino acid sequences of these two genes were analyzed using bioinformatics tools. LuxI consists of 193 amino acids and appears to contain five α-helices and six ß-sheets when analyzed by SSpro8. LuxI belongs to the autoinducer synthetase fa...
Completion of genome projects gives us a lot of information to deal with and analyze. From the genomic sequence data, cellular information can be obtained. The complexity of cellular processes can be analyzed not only by the individual components but also by the systematic approaches. However in general, these approaches are limited by the lack of kinetic information on the metabolism. The ulti...
Metallothioneins are low-molecular-weight proteins capable of covalently binding heavy metal ions due to the presence of many cysteine residues in their sequences. We analyzed the predicted amino acid sequences of 19 metallothionein (7 from Arabidopsis thaliana and 12 from Oryza sativa) and their promoter sequences in silico in order to determine the potential regulatory cis-elements present in...
Altered drug binding may be an important factor in isoniazid (INH) resistance, rather than major changes in the enzyme’s activity as a catalase or peroxidase (KatG). The identification of structural or functional defects in the mutant KatGs responsible for INH resistance remains as an area to be explored. In this connection, the differences in the binding affinity between wild-type (WT) and mut...
Postmenopausal osteoporosis (PO) is a common disease in females >50 years of age worldwide and is becoming an increasing burden to society. The present study aimed to assess the molecular mechanism of PO using bioinformatic methods. The gene expression data from patients with PO and normal controls were downloaded from the ArrayExpress database provided by European Bioinformatics Institute. Fol...
Malaria is still a devastating disease caused by the mosquito-transmitted parasite Plasmodium, particularly Plasmodium falciparum. During the last few years the situation has worsened in many ways, mainly due to malarial parasites becoming increasingly resistant to several anti-malarial drugs. Thus there is an urgent need to find alternate ways to control malaria and therefore it is necessary t...
We report a novel GNRHR mutation in a male with normosmic isolated hypogonadotropic hypogonadism (nIHH). The coding region of the GNRHR gene was amplified and sequenced. Three variants p.[Asn10Lys;Gln11Lys]; [Tyr283His] were identified in the GNRHR coding region in a male with sporadic complete nIHH. The three variants were absent in the controls (130 normal adults). Familial segregation showed...
BACKGROUND The compounds 1,4-napthoquinone (1,4-NQ), bis-(2,4-dinitrophenyl)sulfide (2,4-DNPS), 4-nitrobenzothiadiazole (4-NBT), 3-dimethylaminopropiophenone (3-DAP) and menadione (MD) were tested for antimalarial activity against both chloroquine (CQ)-sensitive (D6) and chloroquine (CQ)-resistant (W2) strains of Plasmodium falciparum through an in vitro assay and also for analysis of non-coval...
