BACKGROUND: Lead (Pb), cadmium (Cd), and arsenic (As) could cause health issues through oxidative stress that is indicated in the elevated tumor necrosis factor-alpha (TNF-α). However, some of the essential elements-selenium (Se), zinc (Zn), cobalt (Co), and copper (Cu)-are cofactors or structural components of antioxidant enzymes. It is suggested that single-nucleotide polymorphisms (SNPs) in the TNF-α gene have different TNF-α responses. This study aims to evaluate the effect of serum TNF-α levels through the interactions between toxic metals and essential elements and how the interactions between the toxic metals and TNF-α SNPs (-1031 T > C, -863 C > A, -857 C > T, -308 G > A, -238 G > A) influence serum TNF-α levels...

BACKGROUND: Iron deficiency anemia in celiac disease is related to impaired duodenal mucosal uptake, due to villous atrophy. Iron enters the enterocytes through an apical divalent metal transporter, DMT1. Different DMT1 transcripts have been identified, depending on the presence of an iron-responsive element that allows DMT1 up-regulation during iron starvation. An intronic DMT1 polymorphism, IVS4+44C>A, has been associated with metal toxicity, and the CC-carriers show high iron levels...

Platelet-derived growth factor receptor has been implicated in many malignant and non-malignant diseases. Platelet-derived growth factor receptor-α is a tyrosine kinase and a side target for imatinib, a revolutionary drug for the treatment of chronic myeloid leukemia that has dramatically improved the survival of chronic myeloid leukemia patients. Given the importance of platelet-derived growth factor receptor in platelet development and its inhibition by imatinib, it was intriguing to analyze the role of platelet-derived growth factor receptor-α in relation to imatinib treatment in the development of imatinib-induced thrombocytopenia in chronic myeloid leukemia patients...

BACKGROUND: Polymorphisms in genes encoding proteins of the leptin-melanocortin pathway have been associated with obesity. The involvement of these polymorphisms with changes in body mass index (BMI) and anthropometric measures could also imply a contribution to the risk of metabolic syndrome (MetS) and metabolic alterations. We evaluated the relationship of leptin-melanocortin system polymorphisms with obesity, MetS, and other metabolic alterations in Southern Chilean individuals. METHODS: Two-hundred individuals were grouped as normoweight (BMI 18...

To develop monoclonal antibodies (McAbs) against chicken interleukin 4 (chIL-4), we subcloned the mature chIL-4 gene into prokaryotic expression vectors pET-28a and pGEX-6P-1, then expressed and purified the recombinant proteins. We immunized BALB/c mice with the purified His-chIL-4 protein and fused the murine splenocytes with SP2/0 after 4 times of immunization. We used the GST-chIL-4 protein as a coating antigen to establish an indirect ELISA to screen positive clones. After screening and 3 rounds of cloning process, we obtained 3 hybridomas that stably secreted McAbs against chIL-4, and named 1G11-3B, 2E5-3D, and 1G11-5H...

Flag leaves (FL) and second leaves (SL) in rice show differential aging patterns during monocarpic senescence. Coordination of aging programs between FL and SL is important for grain yield and quality. However, the molecular bases for differential aging programs between FL and SL have not been systematically explored in rice. Here, we performed mRNA-sequencing of FL and SL at six time points during grain-filling and identified four molecular bases for differential aging programs between FL and SL: phenylpropanoid biosynthesis, photosynthesis, amino acid (AA) transport, and hormone response...
