Abstract
The whole pituitary contents of beta-endorphin and ACTH were found to vary widely among 5 inbred strains of mice. beta-endorphin values were 2.5-fold different and ACTH values 1.5-fold. Strains low in beta-endorphin were also low in ACTH. The existence of genetic differences raises the possibility that there exist, or can be developed, strains with extremely low or high levels of these peptides that would aid research directed at elucidating the physiology of opioid peptides.

Abstract
The amino acid sequences of two previously uncharacterized regions of the mouse anterior pituitary common precursor to adrenocorticotropin (ACTH) and beta-endorphin (pro-ACTH/endorphin) were determined. Portions of the NH2-terminal region of pro-ACTH/endorphin (called the 16K fragment) and the region between ACTH and beta-endorphin (called gamma-lipotropin) were sequenced by Edman degradations of biosynthetically labeled immunoprecipitated proteins and by Edman degradations of purified 16K fragment and beta-lipotropin. With a combination of these two approaches, 29 of the first 34 residues at the NH2-terminal end of the mouse 16K fragment were determined. The NH2-terminal region of the mouse 16K fragment was found to be nearly identical with the homologous porcine and bovine molecules. The complete amino acid sequence of the NH2-terminal region of gamma-lipotropin was determined. In contrast to the highly conserved nature of the 16K fragment, mouse gamma-lipotropin was found to differ substantially from the gamma-lipotropins of other species. Although the NH2-terminal and beta-melanotropin-like regions of the mouse gamma-lipotropin are similar to the corresponding regions of other gamma-lipotropins, the intervening region of mouse gamma-lipotropin is substantially shorter than it is in other gamma-lipotropins. In addition, mouse gamma-lipotropin lacks the pair of basic amino acids that normally mark the proteolytic cleavage site used to produce beta-melanotropin from gamma-lipotropin.

Abstract
The proopiocortin gene is located on chromosome 2 in humans. A 13-kb DNA fragment containing proopiocortin gene sequences was identified in human cells while proopiocortin-related genes sequences of 9.8 and 6.2 kb were present in mouse cells. In human-mouse cell hybrids which contained reduced numbers of human chromosomes and a complete set of mouse chromosomes, the 9.8- and 6.2-kb fragments were always present while the 13-kb fragment segregated with human chromosome 2 and the chromosome 2 enzyme markers acid phosphatase-1 (ACP1), malate dehydrogenase-1 (MDHI), and isocitrate dehydrogenase-1 (IDH1). Analysis of a single cell hybrid with a broken chromosome 2 indicates that the proopiocortin and ACP1 genes are closely linked and in the distal region of the short arm of chromosome 2.

Abstract
Proopiomelanocortin, the common glycoprotein precursor to adrenocorticotropin (ACTH) and beta-lipotropin (beta-LPH), is the most abundant protein synthesized in rat neurointermediate lobes. It represents 30% of the total amount of radioactive proteins obtained after a 1-h pulse incubation with [3H]phenylalanine. Several forms of this protein can be separated by a high-resolution two-dimensional gel electrophoresis technique. The three most abundant species which can be reproducibly characterized by their apparent molecular weights (Mr) and isoelectric points (pI) were called form I (Mr 34 000; pI 8.2), form II (Mr 36 000; pI 8.2), and form III (Mr 35 000; pI 7.3). Additional minor forms, representing together approximately 30% of the total forms I, II, and III combined, are also observed. They have very close molecular weights but differ by their isoelectric points. When glycosylation is prevented by tunicamycin, forms I and II are replaced by a new molecule with the same pI of 8.2 but a slightly lower Mr (32 000). This form is referred to as form T1. Similarly, form III is replaced by form T2 (Mr 33 000; pI 7.3). Forms T1 and T2 are supposed to be nonglycoslyated peptides. They were further characterized by microsequencing and peptide mapping. They both have the same N-terminal amino acid sequence with leucine residues in positions 3 and 11, and they both contain identical [3H]phenylalanine-labeled tryptic fragments, two of them corresponding to the sequences 1-8 of ACTH and 61-69 of beta-LPH. However, a limited digestion with the Staphylococcus aureus (V8 strain) protease generates a collection of peptides different for each form. These results suggest the presence of at least two different gene products corresponding to the major forms of proopiomelanocortin in the rat pars intermedia.

Abstract
Studies of lipotropins, melanotropins and endorphins on one hand, and of adrenocorticotropin on the other, has given rise to the concept of a multipotent precursor molecule recently renamed proopiomelanocortin. The preferential sites of cleavage of the precursor to produce its biologically active components are made of pairs of basic amino acid residues as described for the biosynthesis of beta-MSH and pro-insulin. Such structural feature is also found in other pro-hormone molecules. Pulse chase experiments and secretory studies carried out in both anterior and intermediate lobes of rat pituitary glands revealed the transformation of different forms of the precursor into different end-products, the anterior lobe producing preferentially ACTH and beta-LPH while the intermediate produces mainly the alpha-MSH and beta-endorphin. The multiple forms of precursors seem to differ in their carbohydrate content although at least two different gene products are still possible. The presence of similar peptides in the hypothalamus makes it highly probable that neuropeptides are biosynthesized with similar process. Thus the model of beta-LPH precursor, proposed as early as in 1967, is now applicable to the biosynthesis of all other neuropeptides. Major advances in this field are expected in the 1980s.

Abstract
Sensitive and specific radioimmunoassays for gamma- and beta-endorphin-like peptides (gamma E and beta E) were used to examine the distribution and relationship of these peptides in the pituitary and in microdissected nuclear brain areas of the male rat. In the pituitary, the highest amounts of gamma E and beta E were found in the neurointermediate region of the gland. On a molar basis, gamma E-like immunoreactivity was found to exist as a relatively constant proportion of beta E-like peptides throughout the pituitary. In the brain, while beta E-like peptides were detected in many brain areas, gamma E-like peptides were detected in only a limited number of sites. In most of these areas, the molar ratio of gamma E to beta E-like peptides closely approximated that found in the pituitary. However, in the ventromedial nucleus of the hypothalamus and nucleus accumbens a higher proportion of gamma E to beta E was measured. These results suggest preferential formation of gamma E or related peptides in certain areas of the brain may occur.

Abstract
We report a detailed comparative immunocytochemical mapping of enkephalin, CCK and ACTH/beta-endorphin immunoreactive nerves in the central nervous system of rat and guinea pig. Enkephalin immunoreactivity was detected in many groups of nerve cell bodies, fibers and terminals in the limbic system, basal ganglia, hypothalamus, thalamus, brain stem and spinal cord. beta-endorphin and ACTH immunoreactivity was limited to a single group of nerve cell bodies in and around the arcuate nucleus and in fibers and terminals in the midline areas of the hypothalamus, thalamus and mesencephalic periaqueductal gray with lateral extensions to the amygdaloid area. Cholecystokinin immunoreactive nerve fibers and terminals displayed a distribution similar to that of enkephalin in many regions; but striking differences were also found. An immunocytochemical doublestaining technique, which allowed simultaneous detection of two different peptides in the same tissue section, showed that enkephalin-, CCK- and ACTH/beta-endorphin-immunoreactive nerves although closely intermingled in many brain areas, occurred separately. The distributions of nerve terminals containing these neuropeptides showed striking overlaps and also paralleled the distribution of opiate receptors. This may suggest that enkephalin, CCK, ACTH and beta-endorphin may interact with each other and with opiate receptors.

Abstract
Binding of 3H-enkephalinamide and 3H-naloxone to P2-fractions of whole rat brain homogenate displayed saturable, stereospecific binding to receptor sites with at least two binding sites for 3H-metenkephalinamide (type I: KD = 0.4 nM and Bmax = 35 fmol/mg protein; type II: KD = 5.7 nM and Bmax = 57 fmol/mg protein) and for 3H-naloxone (type I: KD = 1.5 nM and Bmax = 40 fmol/mg protein; type II: KD = 51 nM and Bmax = 255 fmol/mg protein). beta-endorphin and met- and leu-enkephalin produced a concentration-dependent inhibition of 3H-met-enkephalinamide and 3H-naloxone binding with dissociation constants in the nanomolar range, but with very different displacement curves. Purified porcine ACTH (1-39) displaced both 3H-met-enkephalinamide and 3H-naloxone with dissociation constants of 3.4 X 10(-7) M and 1.8 X 10(-6) M, respectively. The synthetic congeners, ACTH (1-32) and to a lesser extent ACTH (1-28) and ACTH (1-24) showed a similar effect, whereas other fragments of ACTH were inactive in concentrations ranging from 10(10) to 10(-6) M. In the same concentration range cholecystokinin congeners (CCK-8 and CCK-4) were without effect. Since ACTH immunoreactive nerves seem also to contain beta-endorphin and furthermore, to show a partially overlapping distribution with the enkephalinergic systems it is possible that the binding of ACTH fragments to opiate receptors is of physiological relevance.

Abstract
Rat pars intermedia cells were incubated for 3 h with the following amino acids: (a) 35S-methionine and 3H-phenylalanine, (b) 3H-valine; and (c) 3H-valine and 3H-lysine. Radioactive gamma-lipotropin, beta-lipotropin and beta-endorphin were purified on carboxymethyl-cellulose and characterized by polyacrylamide disc gel electrophoresis at pH 4.5, molecular weight estimation and micro-sequencing. Rat gamma-lipotropin was shown to differ slightly from ovine gamma-lipotropin in its NH2-terminal amino acid sequence, in containing no methionine and having phenylalanine at position 6, valine at positions 13 and 27, and lysine at position 20. The same variations were observed in the sequence of rat beta-lipotropin, while rat beta-endorphin was shown to be identical to the ovine beta-endorphin. Following a 3-h pulse of rat pars distalis, the cells were extracted with care to avoid beta-lipotropin degradation by proteolytic enzymes, A peptide was purified and identified to be rat beta-endorphin, thus demonstrating that beta-endorphin is biosynthesized in pars distalis and is not an extraction artifact.

Abstract
A synthetic peptide, representing a portion of the 16K (16,000 dalton)-fragment sequence within the pro-adrenocorticotropin/endorphin precursor molecule, potentiates the steroidogenic action of the 1 to 24 portion of adrenocorticotropin [ACTH(1-24)] on the rat adrenal cortex. The peptide has 27 amino acid residues and consists of gamma-melanotropin with a carboxyl terminal extension. It affects both the inner and outer adrenocortical zones of hypophysectomized animals, as evidenced by a synergistic augmentation of corticosterone and aldosterone production, respectively. The peptide can be distinguished from adrenocorticotropin by its activation of cholesterol ester hydrolase and its failure to stimulate cholesterol side-chain cleavage.

Abstract
High molecular weight forms of adrenocorticotropin (ACTH) and endorphin were identified in extracts of guinea pig anterior and intermediate/posterior pituitary. Extracts of anterior pituitary contained ACTH immunoactive material with apparent molecular weights of 36,000, 24,000 and 4,500 daltons. The highest molecular weight form the ACTH co-migrated with a peak of endorphin immunoactive material. No material the size of glycosylated ACTH(1--39) was detected. Separated forms of high molecular weight ACTH prepared from mouse tumor cell culture medium stimulated the same maximal production of steroid as ACTH(1--39) in the guinea pig adrenal cell bioassay. Pro-ACTH/endorphin and ACTH biosynthetic intermediate were two orders of magnitude less potent than synthetic human ACTH(1--39); glycosylated ACTH(1--39) was equipotent to ACTH(1--39) although no similar material was detected in guinea pig pituitary extracts. Isolated guinea pig adrenal cortical cells were incubated with the various separated form of mouse tumor cell ACTH and products synthesized from (3H)pregnenolone were analyzed by two-dimensional thin-layer chromatography. The ratio of cortisol-related to corticosterone-related products was the same in response in glycosylated and nonglycosylated ACTH.
