Vaccine 26(7):7 (2008) PMID 18201806

This study compared: (1) Freund's complete adjuvant and CpG oligodeoxynucleotide (ODN) 2006 in water-in-oil emulsion as adjuvants; and (2) increasing doses of a recombinant ovalbumin-LHRH (ova-LHRH) fusion protein as an antigen for a contraceptive vaccine. Treatment groups (n=8 heifers/group) were: one untreated control group; five groups receiving CpG ODN with different doses of ova-LHRH (1.5; 2.3; 3.4; 5.1; and 7.6mg); and one group receiving 3.4mg ova-LHRH in Freund's. Heifers were immunized at weeks 0 and 14. All vaccine treatments caused gonadal regression and estrus suppression. CpG ODN is a suitable replacement for Freund's for LHRH immunization.

    We identified novel SF-1 target genes using a genome-wide promoter tiling array and a DNA microarray. SF-1 was found to regulate human glutathione S-transferase A (GSTA) family genes (hGSTA1-hGSTA4), a superfamily of detoxification enzymes clustered on chromosome 6p12. All hGSTA genes were up-regula...

    We need to define concepts, relations among concepts, and links to supporting evidence. Some methods already enable representation of concepts and measures at the levels of behavioral and basic biological processes, but a major gap at the level of neural circuitry must be bridged to link basic biolo...
