Human breast tumor tissues have higher concentration of total Oxalate than non-cancerous breast tissues. 13 samples of human breast tumor tissues (Tumor samples) and 12 samples of tumor-adjacent non-cancerous breast tissues (Control samples) were homogenized in 2.75 M hydrochloride acid. The supernatant fractions were analyzed by Capillary Electrochromatography to establish the total concentration of oxalate present in each sample. Results of oxalate concentrations are expressed as μg oxalate/mg of tissue (n = 13 and n = 12 were analyzed for tumor and non-tumor samples, respectively); statistical significance was calculated using Student’s two tailed t -test. ****P value < 0.0001
