In summary, the vitamin pantothenic acid is an integral part of the acylation carriers, CoA and acyl carrier protein (ACP). The vitamin is readily available from diverse dietary sources, a fact which is underscored by the difficulty encountered in attempting to induce pantothenate deficiency. Although pantothenic acid deficiency has not been linked with any particular disease, deficiency of the vitamin results in generalized malaise clinically. In view of the fact that pantothenate is required for the synthesis of CoA, it is surprising that tissue CoA levels are not altered in pantothenate deficiency. This suggests that the cell is equipped to conserve its pantothenate content, possibly by a recycling mechanism for utilizing pantothenate obtained from degradation of pantothenate-containing molecules. Although the steps involved in the conversion of pantothenate to CoA have been characterized, much remains to be done to understand the regulation of CoA synthesis. In particular, in view of what is known about the in vitro regulation of pantothenate kinase, it is surprising that the enzyme is active in vivo, since factors that are known to inhibit the enzyme are present in excess of the concentrations known to inhibit the enzyme.[1]

(±)-Pantothenic acid (3 × 200 mg/kg; IP, single treatment) inhibits VPA-induced decrease in c-Myb and Pim-1 protein expression; incidence of NTD in VPA-injected CD-1 mice dropped to 6.8%, whereas the incidence rate in the untreated group was 23.6%[1].
In utero exposure to valproic acid (VPA) during pregnancy is associated with an increased risk of neural tube defects (NTDs). Although the mechanism by which VPA mediates these effects is unknown, VPA-initiated changes in embryonic protein levels have been implicated. The objectives of this study were to investigate the effect of in utero VPA exposure on embryonic protein levels of p53, NF-kappaB, Pim-1, c-Myb, Bax, and Bcl-2 in the CD-1 mouse. We also evaluated the protective effects of folic acid and (±)-Pantothenic acid on VPA-induced NTDs and VPA-induced embryonic protein changes in this model. Pregnant CD-1 mice were administered a teratogenic dose of VPA prior to neural tube closure and embryonic protein levels were analyzed. In our study, VPA (400 mg/kg)-induced NTDs (24%) and VPA-exposed embryos with an NTD showed a 2-fold increase in p53, and 4-fold decreases in NF-kappaB, Pim-1, and c-Myb protein levels compared to their phenotypically normal littermates (P<0.05). Additionally, VPA increased the ratio of embryonic Bax/Bcl-2 protein levels (P<0.05). Pretreatment of pregnant dams with either folic acid or (±)-Pantothenic acid prior to VPA significantly protected against VPA-induced NTDs (P<0.05). Folic acid also reduced VPA-induced alterations in p53, NF-kappaB, Pim-1, c-Myb, and Bax/Bcl-2 protein levels, while (±)-Pantothenic acid prevented VPA-induced alterations in NF-kappaB, Pim-1, and c-Myb. We hypothesize that folic acid and (±)-Pantothenic acid protect CD-1 embryos from VPA-induced NTDs by independent, but not mutually exclusive mechanisms, both of which may be mediated by the prevention of VPA-induced alterations in proteins involved in neurulation.[2] |

(±)-Pantothenic acid/VPA treatment[2]
Pregnant mice were grouped as described above with one group treated on GD 9 with a single subcutaneous injection of 400 mg/kg VPA in addition to three intraperitoneal injections of 200 mg/kg of (±)-Pantothenic acid dissolved in PBS (pH 7.4), 1 h prior to the VPA injection, immediately after the VPA injection, and 1 h after the VPA injection. A second treatment group was just given VPA (400 mg/kg) on GD 9, and received the (±)-Pantothenic acid vehicle PBS as described above. The corresponding controls were similarly treated with vehicles alone. For the teratology studies, the numbers of dams analyzed were 6, 5, 5, and 13 for the vehicle control, PTA control, VPA, and VPA + PTA treatment groups, respectively. For analysis of proteins, the number of dams treated varied between 3 and 9 from which embryos were pooled. The FA/PTA dosing regime was based on a study performed by Sato et al., 1995, in which they observed a significant decrease in NTDs using this PTA dosing schedule. |

Pantothenic acid is a member of the class of pantothenic acids that is an amide formed from pantoic acid and beta-alanine. It has a role as a plant metabolite. It is a conjugate acid of a pantothenate.
DL-Pantothenic acid has been reported in Daphnia pulex, Drosophila melanogaster, and other organisms with data available. See also: Pantothenic Acid (annotation moved to); 4-Deoxypyridoxine (annotation moved to). hus, other physiological regulatory factors (which are largely unknown) must counteract the effects of these inhibitors, since the pantothenate-to-CoA conversion is operative in vivo. Another step in the biosynthetic pathway that may be rate limiting is the conversion of 4'-phosphopantetheine (4'-PP) to dephospho-CoA, a step catalyzed by 4'-phosphopantetheine adenylyl-transferase. In mammalian systems, this step may occur in the mitochondria or in the cytosol. The teleological significance of these two pathways remains to be established, particularly since mitochondria are capable of transporting CoA from the cytosol. Altered homeostasis of CoA has been observed in diverse disease states including starvation, diabetes, alcoholism, Reye syndrome (RS), medium-chain acyl CoA dehydrogenase deficiency, vitamin B12 deficiency, and certain tumors. Hormones, such as glucocorticoids, insulin, and glucagon, as well as drugs, such as clofibrate, also affect tissue CoA levels. It is not known whether the abnormal metabolism observed in these conditions is the result of altered CoA metabolism or whether CoA levels change in response to hormonal or nonhormonal perturbations brought about in these conditions. In other words, a cause-effect relation remains to be elucidated. It is also not known whether the altered CoA metabolism (be it cause or result of abnormal metabolism) can be implicated in the manifestations of a disease. Besides CoA, pantothenic acid is also an integral part of the ACP molecule.[1] |
