A reliable result obtained by qRT-PCR highly depends on accurate transcript normalization using stably expressed reference genes. However, the transcript levels of traditional reference genes are not always stable. Also, the inaccurate normalization could easily lead to the false conclusions. In this report, by using geNorm and NormFinder algorithms, 12 candidate reference genes were evaluated in...
We evaluated the impact of low pH and aluminum (Al) on the leaves and roots of Plantago almogravensis Franco and Plantago algarbiensis Samp., focusing on energy partitioning in photosystem II, H2O2 levels, lipid peroxidation, electrolyte leakage (EL), protein oxidation, total soluble protein content and antioxidant enzyme activities. In both species, Al triggered more changes in oxidative metabolism...
Manganese (Mn) is an essential trace element and trivalent Mn complexes have been used as oxidation catalysts and enzyme mimetics. We studied the cytotoxicity of Mn(III) derivatives of citrate, pyrophosphate and salicylene diamine (respectively, MnCit, MnPPi and EUK8) toward HeLa cells stressed by ultraviolet irradiation and the effect of the co-administration of ascorbate and para-amino salicylate...
The primary objective of this research project is explore a possible adipogenic effect of iron and/or copper in albino Wistar rats kept on standard (STD) and high-fat (HFD) diets. The female Wistar rats in the study were divided into eight experimental groups (n = 6). Rats maintained on STD and HFD received 3 mg/l FeSO4·7H2O, 4.88 mg/l CuSO4 and a combination of 1.5 mg/l FeSO4·7H2O and 2.44 mg/l CuSO...
Iron is an essential element for oceanic microbial life but its low bioavailability limits microorganisms in large areas of the oceans. To acquire this metal many marine bacteria produce organic chelates that bind and transport iron (siderophores). While it has been hypothesized that the global production of siderophores by heterotrophic bacteria and some cyanobacteria constitutes the bulk of organic...
Silver nanoparticles possess antibacterial effect for various bacteria; however mechanisms of the interaction between Ag-NPs and bacterial cells remain unclear. The aim of our study was to obtain direct evidence of Ag-NPs penetration into cells of Gram-negative bacterium S. typhimurium and Gram-positive bacterium S. aureus, and to study cell responses to Ag-NPs. The Ag-NPs (most 8–10 nm) were obtained...
Multiple sclerosis (MS) is a neurodegenerative disease caused by recurring attacks of neuroinflammation leading to neuronal death. Immune-suppressing gold salts are used for treating connective tissue diseases; however, side effects occur from systemic spread of gold ions. This is limited by exploiting macrophage-induced liberation of gold ions (dissolucytosis) from gold surfaces. Injecting gold beads...
The objective of this study was to compare the oxidative stress induced in rat internal organs by the administration of the following clinically used intravenous (IV) iron (Fe) containing compounds: iron sucrose (IS), iron dextran (ID), ferric carboxymaltose and ferumoxytol. Groups of six adult rats received 1 mg/kg of each compound weekly for 5 doses. Seven days following the last dose, animals were...
Drug induced toxicity and drug resistance are the major impediments to successful application of cancer chemotherapy. Therefore, selective targeting of the key biochemical events of the malignant cells may have a great therapeutic potential in specifically kill the cancer cells. We have evaluated in vitro the cytotoxic efficacy of a previously reported copper complex viz. copper N-(2-hydroxy acetophenone)...
The association of arbuscular mycorrhizal fungi (AMF) with the roots of Lindenbergia philippensis (Cham.) Benth., sampled from a Zn-contaminated settling pond at a zinc smelter, significantly enhanced Zn accumulation (72,540 ± 5,092 mg kg−1 dry weight) in rhizosphere sediment amended with 1,000 mg L−1 of Zn sulfate solution compared to fungicide-treatments that suppressed AMF colonization. This can...
Copper chelation regulates the production of inflammatory mediators in vivo during vascular inflammation and atherogenesis. Little is known about how the copper egress pump ATP7A regulates the production of these mediators. In this study, we isolated ATP7A deficient macrophages (MΦ) from the peritoneal cavity of blotchy mice and identified the lipopolysaccharide (LPS)-induced inflammatory mediators...
The present research is aimed to characterize the potential efficiency of two chelators after chromium(VI) administration for 60 days following two doses of 15 and 30 mg/kg chromium(VI) per body weight daily to male rats. However, the hypothesis that the two chelators might be more efficient as combined therapy than as single therapy in removing chromium(VI) from rat organs was considered. In this...
In the present study, the interaction between GC-rich sequence of bcl-2 gene P1 promoter (Pu39) and two ruthenium (II) polypyridyl complexes, [Ru(bpy)2(tip)]2+ (1) and [Ru(phen)2(tip)]2+ (2), was investigated by UV–Visible, fluorescence spectroscopy, circular dichroism, fluorescence resonance energy transfer melting assay and polymerase chain reaction stop assay. Those experimental results indicated...
