摘要: Newborn larvae (NBL) and adult (Ad) stage-specifically expressed genes or members of gene families of Trichinella spiralis were identified by suppression subtractive hybridization (SSH)dagger. Six cDNA clones were identified as NBL stage-specific, including 1 member of the T. spiralis gene family encoding glutamic acid-rich proteins, 2 clones encoding novel serine proteases, 2 closely related clones encoding proteins that are members of a deoxyribonuclease 11 (DNase I I)-like family and 1 clone with no similarity to known genes. Four stage-specific clones encoding homologues of retinoid X receptor, caveolin, C2H2 type zinc finger protein and a putative protein with no homology to known sequences were obtained from 3-day-old adult worms. One gene specifically up-regulated in the 5-day-old adult worms encoding a putative cuticle collagen was also identified.
