The cancer no-effect levels for glyphosate, based on rat and mouse lifetime feeding studies, are 1,000 and 1,500 mg/kg/day, respectively (Williams et al. 2000).
For PCR amplification, sequence-specific oligonucleotide primers for the genes of interest were designed (Bioneer, Daejeon, Korea) based on rat and human sequences in the GenBank database (Table 1).
The injections were performed once daily for 10 days based on rat weight and clinical protocol.
All GAK plasmids were based on rat GAK and have been described previously (Zhang et al. 2005).
Although official RfDs have not been established for PFOA or PFOS, provisional RfDs based on rat carcinogenesis and multigenerational studies have been suggested (PFOS, 0.025 μg/kg/day; PFOA, 0.333 μg/kg/day) (Gulkowska et al. 2006).
Internal PCR products for X. laevis TRPM8 and TRPM8-b were obtained using PCR primers designed to amplify conserved regions within each gene (based on rat, human, chick, and X. tropicalis genome sequences), and the resulting sequence information was used to obtain complete transcript sequences using 5' and 3' SmartRACE (Clontech).
The assignment of toxicity class for Leadscope chemicals was based on rat data only and chemicals have been classified as carcinogens if at least one of the two genders (male or female rat) was labelled in Leadscope as positive or intermediate level carcinogen.
Interestingly, the increased osteopontin adhesion in CD44s-Separate cells disagrees with a previous conclusion that CD44 variants, but not CD44s, facilitated osteopontin binding to allow migration[ 29]; however, these data were based on rat pancreatic carcinoma, rat fibrosarcoma, and mouse melanoma cells, and pertained to CD44v4-7, not CD44v7-10.
Stapling peptides are based on rat syntaxin 1 (GenBank: EDM13396.1) and were synthesized by Peptide Synthetics, UK, and stored in DMSO.
Because shotgun sequencing was only done in the wild rat 1, we cannot make a direct comparison between wild rat-based SNP discovery and SNP discovery based on rat strains separately.
In vitro studies performed in the late '90 s and based on rat or human hearts isolated with the Langendorff technique demonstrated a direct pathogenic role of antibodies from mothers of children with CHB, as perfusion of hearts with maternal IgG containing anti-Ro and anti-La antibodies induced bradycardia and complete AV block within 15 minutes [ 49, 50].
