Abstract Moderately low protein (MLP) diets can help decrease nutrient excretion from the swine production. However, MLP diets negatively impact growth performance. We hypothesized that supplementing MLP diets with phytogenics may reduce the negative effects of these diets on growth. The objective of this study was to investigate the effect of a phytogenic water additive (PWA; Herbanimal®) on growth performance, blood metabolite and gene expression of amino acids transporters in pigs fed with MLP diets. Forty-eight weaned barrows were allotted to six dietary treatments (n = 8) for 4 weeks: >CON-NS: standard protein diet-no PWA; CON-LS: standard protein diet-low PWA dose (4 ml/L); CON-HS: standard protein diet-high PWA dose (8 ml/L); LP-NS: low protein diet-no PWA; LP-LS: low protein diet-low PWA dose (4 ml/L); LP-HS: low protein diet- high PWA dose (8 ml/L). Feed intake and body weight were recorded daily and weekly, respectively. At week 4, blood and tissue samples were collected and analyzed for metabolites using a chemistry analyzer and amino acid transporters using qPCR, respectively. The data were analyzed by univariate GLM (SPSS®) and the means were separated using paired Student’s t-test corrected by Benjamini-Hochberg. Pigs fed CON-HS improved the average daily gain and serum calcium and phosphorus concentrations compared to CON-NS. Pigs fed LP-LS had higher serum phosphorus and blood urea nitrogen compared to the pigs fed with LP-NS. The mRNA abundance of SLC7A11 in the jejunum was lower in CON-LS and CON-HS compared to CON-NS. Additionally, mRNA abundance of SLC6A19 in the jejunum of pigs fed with LP-LS was higher compared to LP-NS and lower in CON-HS relative to pigs fed with CON-LS. In conclusion, PWA improved the growth performance of pigs fed standard protein diets but not low protein diets. Further, the PWA improved the concentrations of blood calcium and phosphorous in pigs fed MLP diets.

In our previous study, we have shown that maternal low protein diet (LPD, 9% casein vs 18% casein control) fed exclusively during the rat preimplantation period (0–4.25 day postcoitum) induced low birth weight, altered postnatal growth and hypertension in a gender-specific manner. In this study, we investigated the effect of maternal LPD restricted only to the preimplantation period (switched diet) or provided throughout gestation on fetal growth and imprinted gene expression in blastocyst and fetal stages of development. Male, but not female, blastocysts collected from LPD dams displayed a significant reduction (30%) inH19mRNA level. A significant reduction inH19(9.4%) andIgf2(10.9%) mRNA was also observed in male, but not in female, fetal liver at day 20 postcoitum in response to maternal LPD restricted to the preimplantation period. No effect on the blastocyst expression ofIgf2Rwas observed in relation to maternal diet. The reduction inH19mRNA expression did not correlate with an observed alteration in DNA methylation at theH19differentially methylated region in fetal liver. In contrast, maternal LPD throughout 20 days of gestation did not affect male or femaleH19andIgf2imprinted gene expression in fetal liver. Neither LPD nor switched diet treatments affectedH19andIgf2imprinted gene expression in day 20 placenta. Our findings demonstrate that one contributor to the alteration in postnatal growth induced by periconceptional maternal LPD may derive from a gender-specific programming of imprinted gene expression originating within the preimplantation embryo itself.

Abstract This study investigates the mechanism by which maternal protein restriction induces hepatic autophagy-related gene expression in the offspring of rats. Pregnant Sprague-Dawley rats were fed either a control diet (C, 18% energy from protein) or a low-protein diet (LP, 8.5% energy from protein) during gestation, followed by the control diet during lactation and post-weaning. Liver tissue was collected from the offspring at postnatal day 38 and divided into four groups according to sex and maternal diet (F-C, F-LP, M-C, and M-LP) for further analysis. Autophagy-related mRNA and protein levels were determined by real-time PCR and Western blotting, respectively. In addition, chromatin immunoprecipitation (ChIP) was performed to investigate the interactions between transcription factors and autophagy-related genes. Protein levels of p-eIF2a and ATF4 were increased only in the female offspring born to dams fed the LP diet. Correlatively, the mRNA expression of hepatic autophagy-related genes including Map1lc3b, P62/Sqstm1, Becn1, Atg3, Atg7, and Atg10 was significantly greater in the F-LP group than in the F-C group. Furthermore, ChIP results showed greater ATF4 and C/EBP homology protein (CHOP) binding at the regions of a set of autophagy-related genes in the F-LP group than in the F-C group. Our data demonstrated that a maternal LP diet transcriptionally programmed hepatic autophagy-related gene expression only in female rat offspring. This transcriptional program involved the activation of the eIF2α/ATF4 pathway and intricate regulation by transcription factors ATF4 and CHOP.

Concentrating Defect

Protein restriction and hypercalcemia result in a urinary concentrating defect in rats and humans. Previous tubular perfusion studies show that there is an increased active urea transport activity in the initial inner medullary (IM) collecting duct in low-protein diet (LPD) and vitamin D (Vit D) animal models. To investigate the possible mechanisms that cause the urinary concentrating defect and to clone the new active urea transporter, we employed a modified two-tester suppression subtractive hybridization (ttSSH) approach and examined gene expression induced by LPD and Vit D in kidney IM base. Approximately 600 clones from the subtracted library were randomly selected; 150 clones were further confirmed to be the true positive genes by slot blot hybridization with subtracted probes from LPD and Vit D and sent for DNA sequencing. We identified 10 channel/transporter genes that were upregulated in IM base in LPD and Vit D animal models; 8 were confirmed by real-time PCR. These genes include aquaporin 2 (AQP2), two-pore calcium channel protein 2, brain-specific organic cation transporter, Na+- and H+-coupled glutamine transporter, and solute carrier family 25. Nine genes are totally new, and twelve are uncharacterized hypothetical proteins. Among them, four genes were shown to be new transmembrane proteins as judged by Kyte-Doolittle hydrophobic plot analysis. ttSSH provides a useful method to identify new genes from two conditioned populations.
