Interaction of steroid hormones with androgen receptor sites of mouse submandibular gland.

Mouse submandibular gland salivary apomucin contains repeated N-glycosylation sites.

A cDNA clone encoding mouse submandibular gland salivary mucin apoprotein was isolated and characterized. The mucin cDNA encodes a protein of 273 amino acids with a calculated molecular weight of 29,606. This apomucin is approximately 60% Thr, Ser, and Pro, and has a pI of 11.25. In addition to the signal sequence, the apomucin can be divided into four structural domains. The first of these con...

Interaction of glucocorticoid receptor-steroid complexes with acceptor sites.

The binding of the "activated" receptor-glucocorticoid complexes of cultured rat hepatoma cells to nuclei, chromatin, and DNA has been studied under cell-free conditions. A critical factor in determining the shape of the binding curve is shown to be an inhibitory material which is present in crude cytosol and which can be removed without destroying the receptor-steroid complex. These and other ...

HYDATID DISEASE OF THE SUBMANDIBULAR GLAND

Echinococcosis is a tissue infection of the human caused by the larval stage of Echinococcus granulosus or E. multilocularis. Hydatid cyst of the head and neck region is uncommon and involvement of the salivary glands, especially the submandibular gland, is very rare. In this article, a case of submandibular gland hydatid cyst is reported in a patient who presented with swelling of this are...

Induction of androgen receptor formation by epithelium-mesenchyme interaction in embryonic mouse mammary gland.

The role of tissue interaction in the development of hormone responsiveness was studied in the embryonic mammary gland of the mouse, which becomes sensitive to testosterone on day 14. Previously, the mesenchyme had been identified as the sole target tissue for the hormone, although it was also demonstrated that its response to testosterone required the presence of mammary epithelium. Using auto...
