Progression Of Atherosclerosis

Introduction Malondialdehyde/Acetaldehyde (MAA) modified proteins have been suggested to play a role in the development/progression of atherosclerosis. Circulating antibodies directed against these proteins have recently been shown to be associated with the severity of the disease. More specifically, the isotype of the antibody to MAA correlated with either an acute MI (IgG) or stable plaque formation (IgA) formation. MAA is thought to form as a result of the oxidation of fat(s) and thus the concentration and antibody response should reflect the amount of fat in the diet. Objective The purpose of this study was to evaluate the antibody responses to MAA modified proteins following immunization and high fat western diet feeding in rats. Methods Male Sprague Dawley rats were immunized with MAA-modified protein weekly for 5 weeks and then assayed for antibodies to these proteins. Animals were then separated into the following groups: chow sham, chow MAA immunized, high fat sham, and high fat MAA immunized. The high fat animals were fed a Western diet with 2-thiouracil for 12 weeks, bled every 3 weeks, and serum assayed for the presence of circulating MAA antibodies. Results Prior to feeding with high fat diet, rats immunized with MAA-modified protein had a significant increase (P<0.001) in serum antibodies directed against these modified proteins compared to controls (N of 4 per group). Following feeding of high fat diet antibody concentrations increased 6 fold in the high fat MAA immunized group compared to the chow MAA immunized group (P<0.05). Antibodies in the high fat sham and chow sham had only minimal increases in antibodies to these proteins. Conclusions These data demonstrate that following immunization with MAA-modified proteins, circulating antibodies are produced that increase following consumption of a high fat Western diet. It suggests that MAA-modified proteins are produced at low levels following normal diet, producing antibodies which act as a normal clearance method for altered protein. When high fat consumption increases these antibody levels are increased in response to the oxidative stress. Implications Use of these antibodies as a biomarker in the future may help predict the onset or progression of atherosclerosis.

Food Intake Patterns

The hypothesis that BHE/Cdb rats with mutations in their mitochondrial genome might accommodate this mutation by changing their food intake patterns was tested. Four experiments were conducted. Experiments 1 and 2examined food intake patterns of BHE/Cdb rats fed a stock diet or BHE/Cdb and Sprague-Dawley rats fed a high-fat diet from weaning. Experiment 3 examined the daily rhythms of respiration and heat production in these rats at 200 days of age. Experiment 4 examined the effects of diet composition on these measurements at 50-day intervals. The Sprague-Dawley rats, regardless of diet, had the typical day-night rhythms of feeding and respiration. In contrast, the BHE/Cdb rats fed the high-fat diet showed normal rhythms initially, but with age, these rhythms were attenuated. The changes in rhythms preceded the development of glucose intolerance.
