Author:Du Plessis, EM; Theron, J; Berger, E; Louw, MEDate:Nov 2007A 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
Author:Van Dijk, JP; Leifert, C; Barros, E; Kok, EJDate:Jan 2010Since 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
Author:Mahaye, Ntombikayise; Thwala, Melusi; Cowan, DA; Musee, EuniceDate:Jul 2017Engineered 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
Author:Truter, JC; Van Wyk, JH; Oberholster, Paul J; Botha, AMDate:Feb 2014Acid 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
Author:Magagula, L; Gagliardi, M; Naidoo, Jerolen; Mhlanga, MusaDate:Aug 2017Termed '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
Author:Naidoo, Jerolen; Brackin, R; Khutlang, Rethabile; Savulescu, A; Mhlanga, MusaDate:Jun 2014The 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
Author:O'Kennedy, Maretha M; Burger, JT; Berger, DKDate:Dec 2001Elite 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 ...Read more
