Abstract
The amino acids in methanol-soluble extracts of Xenopus oocytes were measured using a method involving precolumn derivatization with phenylisothiocyanate and reverse phase HPLC of the derivatized amino acids. This technique allows the estimation of asparagine and glutamine pools in oocytes, estimated as 70 and 283 pmoles per oocyte, respectively. The pool sizes of the other amino acids were similar to previously reported results obtained using conventional ion exchange chromatography and postcolumn derivatization with ninhydrin. The advantages of the method developed here include picomolar sensitivity and the enhanced resolution of asparagine and glutamine from other amino acids. The kinetics of aspartic acid and asparagine utilization were monitored following microinjection of oocytes with [3H]aspartic acid and [14C]asparagine. The aspartic acid pool turned over rapidly with a half-time of < 30 min. The asparagine pool was metabolized much more slowly and appeared to be utilized almost completely for protein synthesis. The absolute rate of protein synthesis in oocytes was calculated from the incorporation data and chemical pool measurements as approximately 25 ng/hr-oocyte. The methodology developed here may be useful in experimental situations involving limited amounts of biological material.

Abstract
Ham's F-10 medium was analyzed biochemically before and after growth of murine and human embryos. Ham's F-10 medium (280 mosm/kg, pH 7.4) alone, by means of reverse-phase high-performance liquid chromatography, demonstrated one major hydrophilic peak, which eluted at 4 to 8 minutes in a 10% to 48% acetonitrile gradient. This peak showed a single peptide of 50 kilodaltons in one-dimensional polyacrylamide gel electrophoresis and size exclusion high-performance liquid chromatography. After the growth of two-cell murine embryos to eight-cell embryos or blastocysts, the major hydrophilic peak was greatly reduced or absent in the culture medium, and in turn a major hydrophobic peak appeared that eluted at 29 minutes. The major hydrophobic peak could not be focused in one-dimensional polyacrylamide gel electrophoresis, but a high content of polar and nonpolar amino acids was revealed in N-terminal sequencing and mass spectrometric analysis. This shift in the peaks was not detected when embryos were cultured in the presence of 0.02% sodium azide. In vitro culture of human zygotes from the pronuclear stage to two to eight cells caused a similar disappearance of the major hydrophilic peak concomitant with the appearance of one to three major hydrophobic peaks in the culture medium. We conclude that the change in profile of culture medium from hydrophilic to hydrophobic peaks on high-performance liquid chromatography is indicative of the metabolic pattern of murine and human embryos. These data also indicate that murine and human embryos do not secrete any major peptide during their development in vitro.

Abstract
Messenger RNA half-life in vegetatively growing cells of Dictyostelium discoideum was determined using a uridine pulse-chase procedure. In these experiments, mRNA decayed in a complex fashion, and consisted of at least two major components, one with a half-life of about 50 min and a second with a half-life of about 10 hr. These results independently confirm our previous studies on the decay of mRNA extracted from actinomycin D-treated cells. Since these results were in apparent conflict with half-life determinations obtained with a combination of actinomycin D and daunomycin (J. P. Margolskee and H. F. Lodish, 1980a, Dev. Biol. 74, 37-49), we have also studied mRNA half-life in cells treated with a combination of both drugs and found that simultaneous use of both drugs leads to accelerated mRNA decay and other noticeable side effects. In light of our observations, we have suggested an alternative to conclusions drawn by others with respect to mRNA synthesis and stability in Dictyostelium development.

Abstract
Cytoplasmic polyadenylated RNA of myogenic cells was shown to decay with biphasic kinetics, suggesting the existence of two main populations of mRNA with respect to stability. In the present study, the stability of mRNA extracted from actinomycin-D-treated cultures of a myogenic cell line was tested by its capacity to direct protein synthesis in the wheat germ cell-free system. The products were analyzed by dodecylsulphate/polyacrylamide gel electrophoresis. All major radioactive bands found in gels used for analyzing the products of the cell-free system directed by polyadenylated RNA extracted from untreated cultures were also found in similar gels containing products of RNA extracted after many hours of application of actinomycin D. The capacity to code for specific protein bands decays with a half-life ranging between 11 and 40 h. No fast-decaying translatable mRNA could be detected by this method. Instead, it was found that during the first 4--6 h following application of actinomycin D, the capacity of RNA to stimulate incorporation of amino acids into total acid-insoluble material increased by 20--30%. The synthesis of specific products increased by up to 100%. The possibility that the fast-decaying polyadenylated RNA or part of it is nontranslatable RNA is discussed.

Abstract
The two calcium antagonistic agents lanthanum and tetracaine cause severe disturbances in the secretory process of the exocrine pancreas, including inhibition of the rate of protein synthesis and exocytosis. The former effect resulted mainly from the inhibition of amino acid transport. Lanthanum in a concentration up to 1 mM inhibited transport of different species of amino acids in an unspecific way whereas tetracaine interfered specifically with the Na+ -dependent transport system for neutral amino acids (14C-alpha-amino-isobutyric acid). Na+ -dependent transport of neutral amino acids (3H-leucine) was not affected. Transport inhibition was correlated to the acitvity of the Na+, K+ -ATPase system which was measured in isolated plasma membrane fractions. At higher concentrations (5-10 mM) some uptake of lanthanum into the cells by limited endocytosis was observed. At lower concentrations lanthanum seemed to bind exclusively to certain components of the plasms membrane, mainly at the lateral and basal cell surface. Even at a concentration of 5-10 mM no binding to the apical surface occurred. Similarly no binding of lanthanum was observed to the limiting membrane of isolated zymogen granules, while mitochondria, contained in the same fraction showed considerable binding affinity. The action of lanthanum and tetracaine on membrane carrier systems did not affect the interior organization of the plasma membrane. Particle density and distribution in freeze-fracture replicas as well as the submembrane microfilamentous=microtubular system and the junctional elements remained unaffected.

Abstract
We examined the kinetics of incorporation of [3H]adenine into polyadenylate-containing ribonucleic acid [poly(A)-containing RNA] in yeast. The total poly(A)-containing RNA from spheroplasts and intact cells and the polysomal poly(A)-containing RNA exhibited similar incorporation kinetics. At 30 C half-saturation of the pool of poly(A)-containing RNA with label occurred in approximately 22 min. Since precursor pools appeared to require 5 min to saturate with label, we conclude that at 30 C messenger RNA molecules in yeast decay with an average half-life of 17 min.

Abstract
Optimal conditions for incorporation of radioactive amiino acids into protein by slices of brain have been established. Protein synthesis continued for at least 4 h at 35 degrees. The highest incorporation of amino acids into protein was obtained with 20-50 mg wet weight per ml incubated at pH 7.1. After incubation of 500 mg of slices acidic proteins were separated by saltfractionation and electrophoresis on 14% polyacrylamide gel. The most acidic band was shown to contain S-100 protein. Indentification was solubility of the protein in 100% (NH4)2SO4, electrophoretic mobility at pH 8.9, precipitation with specific antibodies, and 2-dimensional electrophoresis in polyacrylamide gel. The protein band was insoluble in 50% methanol and contained between 0.06 and 0.2% of the radioactivity present in the total soluble proteins; while other well separated acidic proteins contained about 10 times the radioactivity of S-100 protein.

Abstract
Reexamination of the effects of actinomycin D (AMD) on the intracellular level and rate of synthesis of tyrosine aminotransferase (TAT) in hepatoma tissue culture (HTC) cells reveals that much apparent controversy can be resolved with acknowledgment of the multi-faceted nature of this inhibitor's action. AMD can slow overall protein synthesis and inhibit the degradation of both TAT and its mRNA as well as block the synthesis of RNA. The extent of these secondary actions of the inhibitor depend somewhat upon the growth condition of the cells. The effects of cordycepin (3'-deoxyadenosine) on the metabolism of TAT and its mRNA are also complex, but differ in several respects from those of AMD.
