| Abstract: | Di-octyl phthalate(DOP) is widely used as a plasticizer in the plastics industry.As a result,DOP is often found in marine water ecosystems where many species are exposed to it.Our objective was to evaluate the effect of long-term(14 d) DOP exposure(2.6,7.8,or 31.2 mg/L) on the expression of immunerelated genes in Tegillarca granosa.The expression of small heat shock protein(sHSPs) and tissue inhibitor of metalloproteinase(TIMP) were highest in clams exposed to 31.2 mg/L DOP on days 7 and 14.The relative expression of Tg-ferritin,superoxide dismutase(SOD),and metallothionein(MT) increased initially then decreased as the concentration of DOP increased.The hemoglobin of T.granosa(Tg-Hb I) exhibited two distinct expression patterns at two time points.Our results suggest that the immune response of T.granosa against DOP pollution varies depending on the dose.Additionally,we identified some immune-related genes that are promising candidates for biomarkers of DOP. |
