Cadmium (Cd) is associated with male infertility and poor semen quality in humans. Increasing evidence demonstrates that Cd induces testicular germ cell apoptosis in rodent animals. However, the molecular mechanisms of Cd-induced testicular germ cell apoptosis remain poorly understood. In the present study, we investigated the role of endoplasmic reticulum (ER) stress on Cd-evoked germ cell apo...

The heavy metal cadmium is a common environmental contaminant in soils and has adverse effects on crop growth and development. The signaling processes in plants that initiate cellular responses to environmental stress have been shown to be located in the plasma membrane (PM). A better understanding of the PM proteome in response to environmental stress might provide new insights for improving s...

Thermococcus gammatolerans, the most radioresistant archaeon known to date, is an anaerobic and hyperthermophilic sulfur-reducing organism living in deep-sea hydrothermal vents. Knowledge of mechanisms underlying archaeal metal tolerance in such metal-rich ecosystem is still poorly documented. We showed that T. gammatolerans exhibits high resistance to cadmium (Cd), cobalt (Co) and zinc (Zn), a...

Gibberellins (GA) are the decisive players in seed germination whose functionality could be adversely affected by presence of cadmium (Cd); however, underlying mechanisms unclear. Eco-toxicological effects Cd (0, 25, 50, 75, and 100 µM) on early stages ontogenesis a mung bean variety (ML-2056) were investigated. Seed characteristics along with Cd-tolerance index recorded at seventh day germinat...

ZmST1;1, a putative high-affinity sulfate transporter gene expressed in maize (Zea mays) roots, was functionally characterized and its expression patterns were analyzed in roots of plants exposed to different heavy metals (Cd, Zn, and Cu) interfering with thiol metabolism. The ZmST1;1 cDNA was expressed in the yeast (Saccharomyces cerevisiae) sulfate transporter mutant CP154-7A. Kinetic analysi...

Cadmium (Cd) is a heavy metal and is highly toxic to all plant species. However, the underlying molecular mechanism controlling the effects of auxin on the Cd stress response in maize is largely unknown. In this study, the transcriptome produced by maize 'Zheng 58' root responses to Cd stress was sequenced using Illumina sequencing technology. In our study, six RNA-seq libraries yielded a total...

Coeliac disease (CD) is a chronic disease which could stress patients and their family. Although, poor attention has been paid to the quality of life in CD children and to the functioning of families with CD children. The study aims to evaluate the parenting perception of the CD impact and the parenting distress level. A group of 74 parents of CD children compiled the Impact Childhood Illness S...

The MICA/B genes (MHC class I chain related genes A and B) encode for non conventional class I HLA molecules which have no role in antigen presentation. MICA/B are up-regulated by different stress conditions such as heat-shock, oxidative stress, neoplasic transformation and viral infection. Particularly, MICA/B are expressed in enterocytes where they can mediate enterocyte apoptosis when recogn...

The hormetic responses of Lonicera japonica Thunb. to cadmium (Cd) stress were investigated in a hydroponic experiment. The present results showed that root length and total biomass dry weight increased in comparison with the control at low concentrations Cd. The height of the plant exposed to 2.5 and 5 mg L(-1) Cd increased significantly by 11.9% and 12.8% relative to the control, and with the...

Cadmium (Cd) is an environmental and industrial cumulative pollutant that most affects many organs specially the liver. The protective effect of Spirulina, filamentous blue green algae, on Cd – induced oxidative stress and hepatotoxicity was evaluated in male rats. Oral administration of water extract of Spirulina for seven days followed by an acute toxic dose of Cd (3.5 mg kg b.wt. ), reduced ...
