Comparative analysis of testis and ovary transcriptomes in zebrafish by combining experimental and computational tools
(Wiley, 2004)Studies on the zebrafish model have contributed to our understanding of several important developmental processes, especially those that can be easily studied in the embryo. However, knowledge on late events such as gonad ... -
Opportunities in Africa for training in genome science
(Academic Journals, 2004)Genome science is a new type of biology that unites genetics, molecular biology, computational biology and bioinformatics. The availability of the human genome sequence, as well as the genome sequences of several other ... -
Mice and men: Their promoter properties
(PLoS Genetics, 2006)Using the two largest collections of Mus musculus and Homo sapiens transcription start sites (TSSs) determined based on CAGE tags, ditags, full-length cDNAs, and other transcript data, we describe the compositional landscape ... -
Transcriptomic analysis reveal novel genes with sexually dimorphic expression in the zebrafish gonad and brain
(Plosone, 2008)Our knowledge on zebrafish reproduction is very limited. We generated a gonad-derived cDNA microarray from zebrafish and used it to analyze large-scale gene expression profiles in adult gonads and other organs. We have ... -
DDESC: Dragon database for exploration of sodium channels in human
(BMC Cancer, 2008)Sodium channels are heteromultimeric, integral membrane proteins that belong to a superfamily of ion channels. The mutations in genes encoding for sodium channel proteins have been linked with several inherited genetic ... -
DDEC: Dragon databaseof genes implicated in esophageal cancer
(BioMed Central, 2009)Esophageal cancer ranks eighth in order of cancer occurrence. Its lethality primarily stems from inability to detect the disease during the early organ-confined stage and the lack of effective therapies for advanced-stage ... -
Database for exploration of functional context of genes implicated in ovarian cancer
(Oxford Journals, 2009)Ovarian cancer (OC) is becoming the most common gynecological cancer in developed countries and the most lethal gynecological malignancy. It is also the fifth leading cause of all cancer-related deaths in women. The ... -
Genome-wide SNP identification by high-throughput sequencing and selective mapping allows sequence assembly positioning using a framework genetic linkage map
(BioMed Central, 2010)Determining the position and order of contigs and scaffolds from a genome assembly within an organism’s genome remains a technical challenge in a majority of sequencing projects. In order to exploit contemporary technologies ... -
DDPC: Dragon database of genes associated with prostate cancer
(Oxford Journals, 2011)Prostate cancer (PC) is one of the most commonly diagnosed cancers in men. PC is relatively difficult to diagnose due to a lack of clear early symptoms. Extensive research of PC has led to the availability of a large amount ... -
DAMPD: a manually curated antimicrobial peptide database
(Oxford University Press, 2012)The demand for antimicrobial peptides (AMPs) is rising because of the increased occurrence of pathogens that are tolerant or resistant to conventional antibiotics. Since naturally occurring AMPs could serve as templates ... -
The African Coelecanth genome provides insights into tetrapod evolution
(Macmillan Publishers, 2013)The discovery of a living coelacanth specimen in 1938 was remarkable, as this lineage of lobe-finned fish was thought to have become extinct 70 million years ago. The modern coelacanth looks remarkably similar to many of ... -
Trends in Genotypic HIV-1 Antiretroviral resistance between 2006 and 2012 in South African Patients receiving first- and second line antiretroviral treatment regimens
(University of the Western CapePublic Library of Science -- PLoS, 2013)South Africa's national antiretroviral (ARV) treatment program expanded in 2010 to include the nucleoside reverse transcriptase (RT) inhibitors (NRTI) tenofovir (TDF) for adults and abacavir (ABC) for children. We ... -
Blood pressure gradients and cardiovascular risk factors in urban and rural populations in Abia State South Eastern Nigeria using the WHO STEPwise approach
(Public Library of Science, 2013)Background: Developing countries of sub-Saharan Africa (SSA) face a double burden of non-communicable diseases (NCDs) and communicable diseases. As high blood pressure (BP) is a common global cardiovascular (CV) disorder ... -
A diverse array of genetic factors contribute to the pathogenesis of Systemic Lupus Erythematosus
(Biomed Central, 2013)Systemic lupus erythematosus (SLE) is a chronic systemic autoimmune disease with variable clinical presentation frequently affecting the skin, joints, haemopoietic system, kidneys, lungs and central nervous system. It can ... -
Evidence of pervasive biologically functional secondary structures within the Genomes of Eukaryotic Single-Stranded DNA Viruses
(American Society for Microbiology, 2013)Single-stranded DNA (ssDNA) viruses have genomes that are potentially capable of forming complex secondary structures through Watson-Crick base pairing between their constituent nucleotides. A few of the structural elements ... -
Characterizing the emergence and persistence of drug resistant mutations in HIV-1 subtype C infections using 454 ultra deep pyrosequencing
(BioMed Central -The Open Access Publisher, 2013)BACKGROUND: The role of HIV-1 RNA in the emergence of resistance to antiretroviral therapies (ARTs) is well documented while less is known about the role of historical viruses stored in the proviral DNA. The primary ... -
Avihepadnavirus diversity in parrots is comparable to that found amongst all other avian species
(Elsevier, 2013)Avihepadna viruses have previously been isolated from various species of duck ,goose, stork, heron and crane. Recently the first parrot avihepadna virus was isolated from a Ring-necked Parakeet in Poland. In this study, ... -
Evidence that dicot-infecting mastreviruses are particularly prone to inter-species recombination and have likely been circulating in Australia for longer than in Africa and the Middle East
(Elsevier, 2013)Viruses of the genus Mastrevirus (family Geminiviridae) are transmitted by leafhoppers and infect either mono- or dicotyledonous plants. Here we have determined the full length sequences of 49 dicot-infecting mastrevirus ... -
The Influence of N-Linked Glycans on the MolecularDynamics of the HIV-1 gp120 V3 Loop
(PLoS ONE, 2013)N-linked glycans attached to specific amino acids of the gp120 envelope trimer of a HIV virion can modulate the binding affinity of gp120 to CD4, influence coreceptor tropism, and play an important role in neutralising ... -
Challenges of biobanking in South Africa to facilitate indigenous research in an environment burdened with human immunodeficiency virus, tuberculosis, and emerging non-communicable diseases
(Mary Ann Liebert, Inc., 2013)The high burden of infectious diseases and the growing problem of noncommunicable and metabolic disease syndromes in South Africa (SA) forces a more focused research approach to facilitate cutting-edge scientific growth ...
