The expression of genes involved in the control of redox homeostasis and antioxidant defense was studied in macroalga Ulva fasciata Delile in response to 5 and 50 microM CuSO(4). Redox-related genes, methionine sulfoxide reductase A (UfMsrA), thioredoxin (UfTrx), cyclophilin (UfCyp), and ferritin (UfFer) that were up-regulated by excess Cu [Wu, T.M., Lee, T.M., 2008. Regulation of activity and gene expression of antioxidant enzymes in Ulva fasciata Delile (Ulvales, Chlorophyta) in response to excess copper. Phycologia 47, 346-360] were cloned and their expression was compared to superoxide dismutase (UfMnsod and UfFesod), ascorbate peroxidase (UfApx), glutathione reductase (UfGr), and catalase (UfCat). Transcripts of UfMsrA, UfCyp, and UfFer were increased by excess Cu with a peak at 3h and that of UfTrx increased after 6-9h, but not affected by 4-day exposure to excess Cu, except an increase in UfMsrA transcript. Transcripts of UfMnsod, UfFesod, UfApx, UfGr and UfCat can be increased by 4-day exposure to Cu excess [Wu, T.M., Lee, T.M., 2008. Regulation of activity and gene expression of antioxidant enzymes in Ulva fasciata Delile (Ulvales, Chlorophyta) in response to excess copper. Phycologia 47, 346-360] but not by short-term excess Cu treatment, except UfGr whose transcript increased after 3h. Reactive oxygen species involved in up-regulation of antioxidant defense enzymes genes. These results suggest that the expression of genes of antioxidant defense enzymes and UfMsrA are associated with long-term adaptation of U. fasciata to Cu excess and transcription of redox-related genes and UfGr is up-regulated for short-term acclimation.

The hydatid cyst fluid (HCF) of Echinococcus granulosus is a complex biological mixture containing a wide range of proteins of both parasite and host origin. Using a combination of in- and off-gel protein fractionation techniques and tandem mass spectrometry 130 HCF proteins were identified from fertile cysts of sheep and human origin and infertile cysts from cattle. Forty-eight proteins were of parasite origin including Antigen 5 and Antigen B--the most abundant parasite proteins, thioredoxin, low-density lipoprotein receptors, cyclophilin and ferritin. Across the three host species the identified HCF proteins were broadly similar although, based on spectral counts, three proteins, including an antigen B isoform, were more abundant in sheep HCF compared with the fluids of cattle and human origin. Eighty-two host proteins were identified in HCF from the three species. Host plasma proteins were the most abundant, although approximately thirty of the host proteins that were identified are not considered constituents of plasma. The identification of parasite heat shock proteins and annexin A13 exclusively in infertile cysts, along with an increased spectral count for cathepsin B, supports the hypothesis of increased cellular stress and apoptosis as the cause of their infertility.
