Cheng B, Horst I, Mader S, Kowal J
Mol Cell Endocrinol . 1990 Oct; 73(1):R7-12. PMID: 1963413
Adrenal cells from 2-6-month-old young rats (Y cells) and from 19-25-month-old aged male rats (O cells) were adapted to primary monolayer culture. The cultures of Y and O cells appeared...

Cheng B, Horst I, Kowal J
J Steroid Biochem . 1990 Aug; 36(5):493-9. PMID: 2170765
We have previously reported that treatment of cultured mouse adrenal tumor cells with 0.6-1.2 microM monensin, a monovalent carboxylic ionophore, results in disruption of the organized structure of the Golgi...

Cheng B, Horst I, Kowal J
Endocr Res . 1987 Jan; 13(3):243-50. PMID: 2828016
Following 15-30 min exposure to monensin, adrenocorticotropic hormone (ACTH)-stimulated steroidogenesis in cultured adrenal cells is inhibited by 37-48%. Electron microscopic studies reveal that, in monensin-treated cells, the Golgi complexes are...

Ray D, Jansen R, Horst I, Mills N, Kowal J
Endocrinology . 1986 Jan; 118(1):393-407. PMID: 3510121
The concentrations of PRL, corticosterone, and insulin required by long term cultures of normal rat mammary cells to produce alpha-lactalbumin (alpha LA) and the 25,000 mol wt beta-casein were evaluated...

Cheng B, Horst I, Kowal J
Arch Biochem Biophys . 1985 Jun; 239(2):508-16. PMID: 2988453
It has previously been shown that the steroidogenic action of adrenocorticotropic hormone (ACTH) is accompanied by characteristic alterations in cell ultrastructure. These include hypertrophy of the Golgi complex associated with...

Mills N, Ray D, Littlejohn R, Horst I, Kowal J
Anal Biochem . 1984 Apr; 138(1):164-80. PMID: 6329034
The requirements for in vitro mitochondrial protein synthesis have been studied using isolated mitochondria from cultured adrenal Y-1 tumor cells from mice. By reducing the reaction volume to 50 microliter...

Ray D, Horst I, Jansen R, Kowal J
Endocrinology . 1981 Feb; 108(2):573-83. PMID: 7192624
Mammary cells from normal tissue of virginal, pregnant, and lactating rats have been adapted to long term monolayer culture in plastic culture dishes with retention of hormone-responsive functional activity. The...

Ray D, Horst I, Jansen R, Littlejohn R, Kowal J
Endocr Res Commun . 1981 Jan; 8(3):165-78. PMID: 7037364
Cultures of normal rat mammary cells have been developed which produce alpha-lactalbumin (a-LA) for several months in response to physiological levels of corticosterone whereas none is measureable without glucocorticoid. In...
