Phospholipase D from Streptomyces sp. was found to catalyze the transfer reaction of the dipalmitoylphosphatidyl residue from 1,2-dipalmitoyl-3-sn-phosphatidylcholine to thiamin, pantothenic acid, and their derivatives in a biphasic system. The following phosphatidylated compounds were synthesized: 1,2-dipalmitoyl-3-sn-phosphatidylthiamin, 1,2-dipalmitoyl-3-sn-phosphatidylthiamin propyl disulfide, 1,2-dipalmitoyl-3-sn-phosphatidylthiamin tetrahydrofurfuryl disulfide, 1,2-dipalmitoyl-3-sn-phosphatidylpantothenic acid, and 1,2-dipalmitoyl-3-sn-phosphatidyl-pantothenyl ethyl ether.

1. Measurements of brain acetylcholine (ACh) synthesis from precursor [14C]-pyruvate, pantothenic acid (PA) concentration in the brain, and blood ethanol (EtOH) concentration were made in rats treated with either ethanol (5-6 g kg-1 body wt daily) alone or ethanol with PA supplementation (100-200 mg kg-1 body wt daily). EtOH with or without PA was administered orally by either Lieber-Decarli liquid diet for 4 weeks and 4 months or by oral intubation for 1 and 4 days. Matched controls were given either ethanol-free liquid diet or saline. 2. ACh synthesis in the brain of rats treated with ethanol alone for 4 months was significantly (P less than 0.01) inhibited. PA concentration of the brain was diminished to 7.0% of the control value. 3. PA concentration in the brain of rats treated with ethanol plus PA for 4 months was three times that of rats treated with ethanol alone. ACh synthesis in rats with ethanol and PA supplementation was also significantly (P less than 0.01) higher. 4. There was no difference in blood EtOH concentration between rats treated with ethanol with or without PA supplement. 5. The EtOH effect on ACh synthesis and PA concentration in the brain was observed in the chronic treatments but not in the acute treatments. 6. Data suggest that chronic ethanol exposure may decrease ACh synthesis by depleting PA, a precursor for the synthesis of acetyl CoA. Acetyl CoA is an essential substrate for ACh synthesis.

The purpose of this study was to clarify the expression of Na(+) -dependent multivitamin transporter (SLC5A6/SMVT) and its contribution to the supply of biotin and pantothenic acid to the human brain via the blood-brain barrier. DNA microarray and immunohistochemical analyses confirmed that SLC5A6 is expressed in microvessels of human brain. The absolute expression levels of SLC5A6 protein in isolated human and monkey brain microvessels were 1.19 and 0.597 fmol/μg protein, respectively, as determined by a quantitative targeted absolute proteomics technique. Using an antibody-free method established by Kubo et al. (2015), we found that SLC5A6 was preferentially localized at the luminal membrane of brain capillary endothelium. Knock-down analysis using SLC5A6 siRNA showed that SLC5A6 accounts for 88.7% and 98.6% of total [(3) H]biotin and [(3) H]pantothenic acid uptakes, respectively, by human cerebral microvascular endothelial cell line hCMEC/D3. SLC5A6-mediated transport in hCMEC/D3 was markedly inhibited not only by biotin and pantothenic acid, but also by prostaglandin E2, lipoic acid, docosahexaenoic acid, indomethacin, ketoprofen, diclofenac, ibuprofen, phenylbutazone, and flurbiprofen. This study is the first to confirm expression of SLC5A6 in human brain microvessels and to provide evidence that SLC5A6 is a major contributor to luminal uptake of biotin and pantothenic acid at the human blood-brain barrier. In humans, it was unclear (not concluded) about what transport system at the blood-brain barrier (BBB) is responsible for the brain uptakes of two vitamins, biotin and pantothenic acid, which are necessary for brain proper function. This study clarified for the first time that the solute carrier 5A6/Na(+) -dependent multivitamin transporter SLC5A6/SMVT is responsible for the supplies of biotin and pantothenic acid into brain across the BBB in humans.

Liver metabolomic characteristics in three different rat models of deficiency based on ultra-performance liquid chromatography coupled to quadrupole time-of-flight mass spectrometry.
OBJECTIVE
To investigate the mechanism of deficiency syndrome (YDS) by analyzing the liver metabolomic characteristics of three different deficiency rat models METHODS: Following the TCM etiology, for clinical features and pathological manifestations of modern medicine, three kinds of animal models of deficiency were induced and replicated. Totally 48 Sprague-Dawley (SD) male rats were randomly divided into blank group, irritation induced model group, Fuzi-Ganjiang induced model group, and thyroxine-reserpine induced model group. After successful development of model, the ultra-performance liquid chromatography coupled to quadrupole time-of-flight mass spectrometry was carried out to detect metabolites in each group. The metabolites of rat liver were analyzed for the characteristics of their biomarkers. The pathway enrichment analysis and metabolic network construction were performed through various online databases including Metabolite Biology Role, Human Metabolome Database, MetaboAnalyst, and Kyoto Encyclopedia of Genes and Genomes.
RESULTS
The SD rats in the experimental group showed symptoms like less weight gain, reduced diet and water intake, high body temperature, increased liver and kidney indexes, and abnormal liver and kidney tissue morphology. Moreover, the rats showed high increased levels of serum cyclic adenosine monophosphate, estradiol, alanine transaminase, and aspartate aminotransferase and decreased levels of cyclic guanosinc monophosphate and testosterone. We found four key interrelated metabolic pathways in the liver tissue metabolomics, including the biosynthesis of pantothenic acid and coenzyme A, and metabolism of alpha-linolenic acid metabolism, glycerophospholipid metabolism, and sphingolipid.
CONCLUSION
The liver and kidney YDS is closely related to the biosynthesis of pantothenic acid and CoA and abnormal metabolism of α-linolenic acid, glycerophospholipid, and sphingolipid in SD rats.

It is thought that both exercise and dietary composition increase the utilization of, and thus the requirement for, certain water-soluble vitamins. However, there have been no studies evaluating the combined impacts of exercise and dietary composition on vitamin utilization. In this experiment, rats were fed a pantothenic acid (PaA)-restricted (0.004 g PaA-Ca/kg diet) diet containing 5% (ordinary amount of dietary fat) or 20% fat (high fat), and were forced to swim until exhaustion every other day for 22 d. PaA status was assessed by urinary excretion, which reflects body stores of water-soluble vitamins. The urinary excretion of PaA in rats fed a 5% fat diet was not affected by swimming (5% fat + non-swimming vs. 5% fat + swim; p>0.05). Excretion of PaA was decreased by the high-fat diet (5% fat + non-swim vs. 20% fat + non-swim; p<0.05) and synergistically decreased by exercise (20% fat + non-swim vs. 20% fat + swim; p<0.05). There was a significant interaction between exercise and a high-fat diet. Plasma PaA concentrations showed changes similar to those seen for urinary excretion. The experiment was then repeated using rats fed a PaA-sufficient (0.016 g PaA-Ca/kg diet) diet, and PaA excretion was again synergistically decreased by the combination of exercise and a high-fat diet (p<0.05). These results suggest that the combination of exercise and a high-fat diet synergistically increases the requirement for PaA.

Review
The Apicomplexa phylum comprises thousands of distinct intracellular parasite species, including coccidians, haemosporidians, piroplasms, and cryptosporidia. These parasites are characterized by complex and divergent life cycles occupying a variety of host niches. Consequently, they exhibit distinct adaptations to the differences in nutritional availabilities, either relying on biosynthetic pathways or by salvaging metabolites from their host. Pantothenate (Pan, vitamin B5) is the precursor for the synthesis of an essential cofactor, coenzyme A (CoA), but among the apicomplexans, only the coccidian subgroup has the ability to synthesize Pan. While the pathway to synthesize CoA from Pan is largely conserved across all branches of life, there are differences in the redundancy of enzymes and possible alternative pathways to generate CoA from Pan. Impeding the scavenge of Pan and synthesis of Pan and CoA have been long recognized as potential targets for antimicrobial drug development, but in order to fully exploit these critical pathways, it is important to understand such differences. Recently, a potent class of pantothenamides (PanAms), Pan analogs, which target CoA-utilizing enzymes, has entered antimalarial preclinical development. The potential of PanAms to target multiple downstream pathways make them a promising compound class as broad antiparasitic drugs against other apicomplexans. In this review, we summarize the recent advances in understanding the Pan and CoA biosynthesis pathways, and the suitability of these pathways as drug targets in Apicomplexa, with a particular focus on the cyst-forming coccidian, Toxoplasma gondii, and the haemosporidian, Plasmodium falciparum.

BACKGROUND
We aimed to investigate the familial resemblance of dietary intakes, including energy and nutrients, and the family-based heritability of dietary intake in different age-sex dyads of the Tehran cardiometabolic genetic study.
METHODS
This cross-sectional study was conducted on 9,798 participants, aged ≥ 18 years, with complete data in each of the third, fourth, fifth, and sixth surveys of the Tehran Cardiometabolic Genetic study, who were eligible to enter the current study based on inclusion and exclusion criteria. Nutrient intake was determined using a valid and reliable food frequency questionnaire (FFQ). FCOR command of the S.A.G.E. software was used to estimate the intra-class correlation coefficients of all relative pairs to verify the family resemblance of dietary nutrient intakes. Classical likelihood-based is used to assess the family-based heritability of dietary nutrient traits.
RESULTS
There were 4338 families with a mean family size of 3.20 ± 2.89, including 1 to 32 members (2567 constituent pedigrees and 1572 singletons) and 3627 sibships. The mean ± SD age of participants was 42.0 ± 15.2 years, and 44.5% were males. The heritability of nutrient intake ranged from 3 to 21%. The resemblance degree of energy intake and most nutrients between spouses or between parents and children is weak to moderate; however, a high resemblance of intake was observed for some food components, especially among spouses, including trans fatty acids (TFAs) (r:0.70), chromium (r:0.44), fiber(r:0.35), pantothenic acid (r:0.31), and vitamin C(r:0.31). Based on our findings, the resemblance of nutrient intake in spouses was greater than in parent-offspring. The similarity in parent-offspring nutrient intake was different, and the correlation in mother-girls nutrient intakes was greater than other parent-child correlations. Also, the lowest resemblance in nutrient intake was observed among siblings.
CONCLUSIONS
Our findings suggested a weak-to-moderate similarity between the nutrient intakes of parents and offspring. The resemblance degree in nutrient intake varied between different family pairs; the strongest correlation of nutrients was observed between spouses, which includes TFAs, chromium, fiber, pantothenic acid, and vitamin C. The lowest correlation of nutrients was between siblings, such as carbohydrates, thiamine, niacin, and vitamin K. An individual's nutrient intake can somewhat be influenced by genetics, family relationships, and the effects of parents, although the significant influence of environmental factors should not be ignored.
