Stool Phospholipid Signature is Altered by Diet and Tumors
Figure 3
Quantities and distribution of lipid classes recovered from stool samples.
Calculated pmol/g stool values for all detected peaks (both identified and unidentified) from representative class specific spectra were summed for each class of phospholipid. A) The bulk amount of each phospholipid class as determined above is graphed for each treatment group. Comparisons between untreated and AOM-DSS treated animals were analyzed by unpaired t-test. Bars represent mean ± SD, p values as indicated. B) The normalized pmol quantities of PLs were graphed. Chain lengths were summed and similar lengths combined to reduce complexity. Simpson's reciprocal diversity index for each treatment was calculated to determine α diversity. Bars represent means.
