Rat alpha 2u-globulin mRNA expression in the preputial gland
Biochemical Genetics
|April 1, 1985
Summary
Rat alpha 2u-globulin and mouse major urinary proteins (MUP) are homologous. Alpha 2u-globulin mRNA is abundant in rat preputial glands, unlike MUP in mice, suggesting constitutive expression rather than hormonal regulation.
Area of Science:
- Biochemistry
- Molecular Biology
- Genomics
Background:
- Rat alpha 2u-globulin and mouse major urinary proteins (MUP) belong to homologous multigene families.
- These proteins display complex tissue-specific, developmental, and hormonal expression controls.
Purpose of the Study:
- To investigate the expression patterns of alpha 2u-globulin and MUP in rat preputial glands.
- To compare the hormonal regulation of alpha 2u-globulin in preputial glands with liver and lachrymal glands.
Main Methods:
- Analysis of alpha 2u-globulin mRNA levels in rat preputial glands.
- Detection of MUP mRNA in male mouse preputial glands.
- Two-dimensional polyacrylamide gel electrophoresis of alpha 2u-globulin translation products.
Main Results:
- High levels of alpha 2u-globulin mRNA were detected in rat preputial glands.
- MUP mRNA was not detected in male mouse preputial glands.
- Alpha 2u-globulin mRNA concentrations were similar in male and female rat preputial glands, indicating a lack of endocrine regulation.
- Preputial gland alpha 2u-globulin products comigrated with liver and lachrymal gland products.
Conclusions:
- Alpha 2u-globulin genes expressed under hormonal control in liver and lachrymal glands may also be constitutively expressed in the preputial gland.
- This suggests differential regulation of homologous gene families across tissues.
