Proteomic analysis of the effect of diclazuril on second-generation merozoites of Eimeria tenella.

Diclazuril has long been used as an effective benzeneacetonitrile anticoccidial for the control of Eimeria tenella that causes coccidiosis. However, the molecular mechanism underlying the anticoccidial effects of diclazuril remains elusive. In this study, a proteomic analysis of the effect of diclazuril on second-generation merozoites of E.

Nuclear translocation and accumulation of glyceraldehyde-3-phosphate dehydrogenase involved in diclazuril-induced apoptosis in Eimeria tenella (E. tenella).

In mammalian cells, GAPDH (glyceraldehyde-3-phosphate dehydrogenase) has recently been shown to be implicated in numerous apoptotic paradigms, especially in neuronal apoptosis, and has been demonstrated to play a vital role in some neurodegenerative disorders. However, this phenomenon has not been reported in protists. In the present study, we report for the first time that such a mechanism is involved in diclazuril-induced apoptosis in Eimeria tenella (E.

Receptor for activated C kinase ortholog of second-generation merozoite in Eimeria tenella: clone, characterization, and diclazuril-induced mRNA expression.

The receptor for activated C kinase (RACK) cDNA of second-generation merozoites of Eimeria tenella was cloned using reverse transcriptase polymerase chain reaction and rapid amplification of cDNA ends, compared with other species, and then successfully expressed using the pET-28a vector in Escherichia coli BL21 (DE3) (EtRACK). Nucleotide sequence analysis revealed that the full length of the cloned cDNA (1,264 bp) encompassed a 957-bp open reading frame encoding a polypeptide of 318 residues with an estimated molecular mass of 34.94 kDa and a theoretical isoelectric point of 5.

Effect of the diclazuril on Hsp90 in the second-generation merozoites of Eimeria tenella.

Eimeria tenella (E. tenella) is one of the most virulent pathogens of coccidiosis. In apicomplexan parasites, Hsp90 (Heat shock protein 90) is essential for the invasion and survival in host cells.
