The loach is one of the most important fish species in aquaculture in China.
The study of peroxisome proliferator-activated receptors (PPARs) will be
essential for the determination of the functional role of the PPARα and
PPARγ in loach fish. We used immunohistochemistry for PPARα and
PPARγ at some stages of development beginning from the age of 1 month
till the age of 15 months. Our result indicated that, the expression of
PPARα and PPARγ was found in; columnar cells lining intestinal folds,
hepatocytes, blood sinusoids in liver, pancreatic islets, pancreatic acini, the
whole spleen and epithelial cells lining renal tubules of the kidney. The
expression pattern of both PPARα and PPARγ was low at the age of one
month, then reach its highest level at the age of 2 months. Then it decline at
the age of 5 months. Then it re-increase at the age of 7 months and became
low in older ages. The expression of PPARα was higher in comparison with
PPARγ. |
