Weanling crossbred pigs (avg initial wt 6.4 kg) were fed diets containing six levels of threonine to determine the threonine requirement of young pigs fed diets somewhat similar to those used in commercial swine production. The diets (16% crude protein) were composed primarily of grain sorghum, oat groats and soybean meal supplemented with minerals, vitamins, lysine, tryptophan, methionine and isoleucine, and were calculated to be adequate in all nutrients except threonine and crude protein. Threonine levels were .53, .57, .62, .68, .75 and .83% of the diet. There were two trials, each with 96 pigs. The pigs were fed the experimental diets for 28 d. The addition of threonine increased weight gain (P|.02) and feed efficiency (P|.001), with most of the response occurring between .53 and .68% threonine. There was little further response when threonine was increased above .68%. Plasma threonine concentrations increased as dietary threonine increased, with a sharp rise when dietary threonine exceeded .68%.
To the Editor.-. We read with great interest the paper of Järvenpää et al1 about milk protein quantity and quality in the term infant and we agree with the conclusions. In the discussion, referring to their previous study in preterm infants,2 they concluded that their results show a positive correlation between the plasma threonine concentration and the threonine intake but they cannot support our data3 showing that the ability to metabolize a high threonine intake is impaired in preterm infants as compared with term infants.. ...

Histone phosphorylation is sometimes associated with mitosis and meiosis. We have recently identified a phosphorylation of the 127th threonine on TH2A (pTH2A), a germ cell-specific H2A variant, in condensed spermatids and mitotic early preimplantation embryos of mice. Here, we further report the existence of pTH2A at the centromeres in metaphase I spermatocytes and oocytes. Moreover, we identified Haspin, a known kinase for the 3rd threonine on H3, is responsible for pTH2A in vivo. In contrast to the severe meiotic defect in oocytes treated with a Haspin inhibitor, pTH2A-deficient mice, in which the 127th threonine was replaced by alanine, maintained the fertility and exhibited no obvious defect in both oocytes and spermatogenesis ...

A 14-day growth trial was conducted to determine the threonine: lysine ratio necessary to optimize growth performance of the segregated early-weaned (SEW) pig. Twelve experimental diets included two levels of lysine (1.15% and 1.5% apparent digestible lysine) and six apparent digestible threonine: lysine ratios (40, 45, 50, 55, 60, and 65 %) in a 2 x 6 factorial arrangement. Growth performance was improved by feeding 1.5% rather than 1.15% digestible lysine. Growth performance decreased linearly as the digestible threonine: lysine ratio increased. Although a significant quadratic response was not observed, this reduction in growth performance did not appear to occur until the threonine ratio exceeded 45% of lysine on an apparent digestible basis. These data indicate that the threonine requirement for the SEW pig is approximately 45% of digestible lysine ...

The PRC leaderships decision to devote not inconsiderable resources to legal development seems premised on the notion that such development is correlated to overall economic development. To wit, law, legal institutions and legal personnel of the type described in part one are seen as having the potential to foster economic growth and, in particular, foreign involvement in the economy and are to be encouraged for that reason, among others. This is, of course, hardly a new thought. Weber compensated for many a sociological error (as, for example, in his accounts of Chinese life) by explaining how legal rationality spurred the development of capitalist societies by facilitating the predictability he indicates business so prizes (Rheinstein, 1954:29-30). North earned the Nobel Prize by pushing this line of thought further in demonstrating how relative clarity in and security of property rights, spawned in important part through formal legal institutions, had been a prime factor in the rise of major ...

Seversal short-chain alcohols, especially ethanol, is abundent in the natural habitats of Drosophilu melanogaster and alcohol dehydrogenase (ADH) plays a key role in the detoxification ethanol and other alcohols. In general, primary alcohols are converted to aldehydes, and secondary alcohols to ketones by ADH. The purpose of this study is to define the function and regulation mechanism of Adh gene by examing how dietary threonine effects on the expression of the Adh gene during the development of Drosophilu melanogaster. In this study, two other wild type strain, one homozygous for Adh^(F) and one for Adh^(S), from Chunan Korea were used. ADH activity was measured by spectrophotometric method and ADH CRMs was calculated by using radial immunodiffusion. To exam the Adh gene expression, northern hybridization analysis was carried. The rusults obtained were as follows: The activities of Adh^(F) strain were about two fold higher than Adh^(S) strain and ADH CRMs were about 1.5 fold higher. ADH ...
Dietary protein dilution (DPD) promotes metabolic-remodelling and -health but the precise nutritional components driving this response remain elusive. Here, by mimicking amino acid (AA) supply from a casein-based diet, we demonstrate that restriction of dietary essential AA (EAA), but not non-EAA, drives the systemic metabolic response to total AA deprivation; independent from dietary carbohydrate supply. Furthermore, systemic deprivation of threonine and tryptophan, independent of total AA supply, are both adequate and necessary to confer the systemic metabolic response to both diet, and genetic AA-transport loss, driven AA restriction. Dietary threonine restriction (DTR) retards the development of obesity-associated metabolic dysfunction. Liver-derived fibroblast growth factor 21 is required for the metabolic remodelling with DTR. Strikingly, hepatocyte-selective establishment of threonine biosynthetic capacity reverses the systemic metabolic response to DTR. Taken together, our studies of ...

Aberrant expression of cyclin D1, frequently observed in human malignant disorders, has been linked to the control of G1→S cell cycle phase transition and development and progression in carcinogenesis. Cyclin D1 level changes are partially controlled by GSK-3β-dependent phosphorylation at threonine-286 (Thr286), which targets cyclin D1 for ubiquitination and proteolytic degradation. In our continuing studies on the mechanism of prostate cancer prevention by resveratrol, focusing on the role of its recently discovered target protein, quinone reductase 2 (NQO2), we generated NQO2 knockdown CWR22Rv1 using short hairpin RNA (shRNA)-mediated gene silencing approach. We found that, compared with cells expressing NQO2 (shRNA08), NQO2 knockdown cells (shRNA25) displayed slower proliferation and G1 phase cell accumulation. Immunoblot analyses revealed a significant decrease in phosphorylation of retinoblastoma Rb and cyclin D1 in shRNA25 compared with shRNA08. Moreover, shRNA25 cells showed a 37% ...
The catabolic L-serine (L-threonine) deaminase of Saccharomyces cerevisiae allows the yeast to grow on media with L-serine or L-threonine as sole nitrogen source. A mutant, cha1 (catabolism of hydroxyamino acids), lacking this enzyme activity has been isolated. We have cloned the CHA1 gene by complementation of a cha1 mutation. Northern analysis showed that CHA1 mRNA has a size of about 1200 ribonucleotides. CHA1 is probably the structural gene for the enzyme; it is an abundant RNA in cells grown with serine and threonine as nitrogen source, whereas it is not detected when cells are grown on ammonium or proline, i.e., the transcription of the CHA1 gene is induced by serine or threonine. Under induced growth conditions haploid ilv1 CHA1 strains do not require isoleucine, i.e., the catabolic deaminase is able to substitute for the biosynthetic threnonine deaminase encoded by the ILV1 gene. We have identified a nuclear, recessive mutation, sil1, that suppresses ilv1 mutations by increased ...
In the current study, we show for the first time that insulin-stimulated AS160 phosphorylation, measured by the PAS antibody, and specific phosphorylation at sites Ser-588, Thr-642, and Ser-666 are impaired in human skeletal muscle in conjunction with the decrement in insulin action typical with advancing age and a sedentary lifestyle (Figs. 2 and 4). Impaired insulin-mediated AS160 phosphorylation has been reported in other insulin-resistant conditions, including type 2 diabetes (12) and polycystic ovary syndrome (14), using the PAS antibody. The PAS antibody may recognize multiple phosphorylation sites on AS160; however, current research suggests this antibody is limited to only recognizing AS160 phosphorylation on Thr-642 (9,23). More recently, site-specific impairments were identified in patients with type 2 diabetes (Ser-318, Ser-588, and Ser-751) (13) and in healthy individuals after fasting-induced insulin resistance (Ser-588 and Ser-751) (4). The current data (Figs. 2 and 4), in ...
To test this pathway, we traced the metabolic fate of [U-14C]Thr in mESCs with high-performance liquid chromatography (HPLC). 14C was incorporated into Gly and Glu, indicating that Thr was used to synthesize these amino acids (Fig. 2B). In contrast, MEFs incubated with [U-14C]Thr did not exhibit Thr catabolism (fig. S2A). We also traced the fate of [U-13C]Thr in mESCs with LC-MS/MS metabolomics (fig. S2, B to F, and table S1). mESCs used Thr to synthesize acetyl-CoA-derived tricarboxylic acid (TCA) cycle intermediates (Fig. 2, C and D). At steady state, [U-13C]Thr contributed ~20% of the citrate via acetyl-CoA, whereas [U-13C]glucose contributed ~35% via acetyl-CoA (+2 isotopomer). Thus, Thr contributes significantly to the acetyl-CoA pool in mESCs (Fig. 2D). [U-13C]Thr-derived Gly also donated its 13C-methyl group to ultimately generate 5-methyltetrahydrofolate (5mTHF) and SAM (+1 isotopomer), whereas [U-13C]Ser-derived Gly contributed little to the synthesis of these metabolites (Fig. 2, C and ...

Highly conserved threonine residues were noted near the C-terminus of the external surface glycoproteins of HIV-1, SIV, and influenza A virus; this threonine residue was shown to be the efficient target of O-glycosylation on all three viruses. In all three cases, this O-glycosylated threonine was essential for the infectivity of the virus. We will define the functional role of C-terminal threonine glycosylation for HIV-1 and we will develop assays amenable to high throughput screening for the development of antiviral drugs. We will delineate protein-peptide and peptide-peptide interactions that are dependent on the O-glycosylated threonine of gp120. We will also examine whether there are rare examples of naturally-occurring HIV-1 sequences that are functional without an O-glycosylated threonine at this location ...
An obvious necessity for a successful protein-protein binding is a spatial matching. Therefore, it is becoming apparent that Ser/Thr phosphorylation of IRS proteins in close proximity to their PTB (receptor-binding) region affects insulin signaling. We could show that mutation of seven Ser sites located within or in close proximity to the PTB domain of IRS-1 protects it from autologous desensitization as well as desensitization induced by IRS kinases triggered by inducers of insulin resistance (71). Autologous desensitization is exemplified by the atypical PKCζ, which is activated in response to insulin to mediate glucose uptake in adipocytes (7) and skeletal muscle (12, 70) downstream of IRS-1 and PI3K (70). In addition to its role as a mediator of insulin action, PKCζ is involved in a self-attenuated mechanism induced by insulin to negatively regulate the function of IRS proteins upon prolonged insulin stimulation (72, 90). It involves Ser/Thr phosphorylation of IRS proteins, mediated by ...

The experiment was conducted to evaluate the effects of dietary threonine (Thr) supplement on reproductive performance and immune function of the male mice challenged with pseudorabies virus (PRV). Kun-Ming male mice were assigned randomly to four groups with different Thr levels (0.70%, 0.88%, 1.10% and 1.30%). Half of the mice in each group were injected with PRV or phosphate-buffered saline (PBS) after 5 weeks adaptation to diets. The second experiment examined the effects of dietary Thr level on copulation rate, pregnancy rate and average number per litter of PRV- or PBS-challenged male mice that copulated with adult female mice on the 9th day post PRV challenge. Sperm quality and testosterone of mice were decreased after PRV infection, but this effect was attenuated by increasing Thr levels. Copulation and conception rates were increased with increasing Thr levels (P = 0.14), but litter size was not affected (P > 0.05). In the PBS and PRV groups, mice fed higher levels of Thr had increased ...
