Timing of protocol is relative to day of gestation (birth is at 21–22 days in a rat); −10 indicates 10 days prior to mating and 43 days is equivalent to offspring post natal day 21 (weaning). Abbreviations: SHR, spontaneously hypertensive rat; SD, Sprague-Dawley rat; IR, iron restricted diet (iron content 3 mg (kg diet)−1); GTT, glucose tolerance test; HF, Hope Farm low protein diet; SH, Southampton low protein diet; w, postnatal week; ↑, increased; ↓, decreased; ↔, no change; M, male only; F, female only; C, combined male and female; M + F, both male and female considered individually.
