Evaluation of staphylococcus aureus class C non-specific acid phosphatase (SapS) as a reporter for gene expression and protein secretion in gram-negative and gram-positive bacteria

Author: Du Plessis, EM ; Theron, J ; Berger, E ; Louw, ME Date: Nov 2007 A phosphatase secreted by Staphylococcus aureus strain 154 has previously been characterized and classified as a new member of the bacterial class C family of non-specific acid phosphatases. As the acid phosphatase activity can be easily ... Read more
Gene expression profiling for food safety assessment: examples in potato and maize

Author: Van Dijk, JP ; Leifert, C ; Barros, E ; Kok, EJ Date: Jan 2010 Since the mid 1990s, microarray analysis has become one of the few tools that can analyze the entire contents of a cell regarding a specific information type. Especially since the development of whole genome microarrays the technique can be ... Read more
Genotoxicity of metal based engineered nanoparticles in aquatic organisms: A review

Author: Mahaye, Ntombikayise ; Thwala, Melusi ; Cowan, DA ; Musee, Eunice Date: Jul 2017 Engineered nanoparticles (ENPs) are an emerging class of environmental contaminants, but are generally found in very low concentrations and are therefore likely to exert sub-lethal effects on aquatic organisms. In this review, we: (i) highlight ... Read more
The impacts of neutralized acid mine drainage contaminated water on the expression of selected endocrine-linked genes in juvenile Mozambique tilapia Oreochromis mossambicus exposed in vivo

Author: Truter, JC ; Van Wyk, JH ; Oberholster, Paul J ; Botha, AM Date: Feb 2014 Acid mine drainage (AMD) is a global environmental concern due to detrimental impacts on river ecosystems. Little is however known regarding the biological impacts of neutralized AMD on aquatic vertebrates despite excessive discharge into ... Read more
Lnc-ing inflammation to disease

Author: Magagula, L ; Gagliardi, M ; Naidoo, Jerolen ; Mhlanga, Musa Date: Aug 2017 Termed 'master gene regulators' long ncRNAs (lncRNAs) have emerged as the true vanguard of the 'noncoding revolution'. Functioning at a molecular level, in most if not all cellular processes, lncRNAs exert their effects systemically. Thus, ... Read more
Systems biology tools to understand the role of host miRNAs in infection: a closer look at HIV

Author: Naidoo, Jerolen ; Brackin, R ; Khutlang, Rethabile ; Savulescu, A ; Mhlanga, Musa Date: Jun 2014 The discovery of mammalian microRNAs (miRNAs) has greatly enhanced our appreciation for the complexity associated with the regulation of the mammalian transcriptional landscape. Endogenous miRNA pathways mediate the targeted and subtle ... Read more
Transformation of elite white maize using the particle inflow gun and detailed analysis of a low-copy integration event

Author: O'Kennedy, Maretha M ; Burger, JT ; Berger, DK Date: Dec 2001 Elite white maize lines W506 and M37W were transformed with a selectable marker gene (bar) and a reporter gene (uidA) or the polygalacturonase-inhibiting protein (pgip) gene after bombardment of cultured immature zygotic embryos using the ...
