Magnesium is Essential for Preventing Substance P Overload , May 24, 2011, by Byron J. Richards, Board Certified Clinical Nutritionist , “Substance P is a neuropeptide that is typically ”over-heated” in situations of anxiety, depression, digestive bloating, insomnia, fibromyalgia, PTSD, and cardiovascular deterioration. New research shows that one of the first signs of magnesium deficiency1 is that it enables the over-production of substance P.” Read More: [http://www.wellnessresources.com/health/articles/magnesium_is_essential_for_preventing_substance_p_overload/]
Raw shelled pumpkin seeds are a good source of magnesium, zinc, B vitamins and essential fatty acids. A few prenatal clients that I have worked with in the past, who were high risk due to a history of high blood pressure or pre-eclampsia during their first pregnancy, did report that the raw shelled pumpkin seeds that I had recommended they try adding to their diet during their second pregnancy did seem helpful for preventing high blood pressure or pre-eclampsia from reoccurring. So it is also possible that raw unsalted pumpkin seeds may be a beneficial food for use during the perinatal stage for women who hope to prevent autism from developing in their infant during conception or the early weeks of pregnancy.

Tachykinins (substance P, neurokinin A and neurokinin B) are pro-inflammatory neuropeptides that may play an important role in some autoimmune neuroinflammatory diseases. Autoimmunity may have a role in the pathogenesis of autism in some patients.” And an excerpt from the discussion section: “In our series, increased serum levels of anti-ribosomal P protein antibodies were found in 44.3% of autistic patients. This study was the first to investigate serum levels of anti-ribosomal P protein antibodies in autistic children.” [http://www.ncbi.nlm.nih.gov/pmc/articles/PMC3261830/]

[http://iai.asm.org/content/75/3/1137.full] *Cryptosporidiosis is a parasitic infection that can be more of a risk for AIDS patients than for average people — reason unknown — The reason speculatively might be that there is a magnesium deficiency or an elevated calcium level resulting from elevated hormone D levels underlying the increased risk for crypotosporidiosis in AIDS patients.

This article is primarily about a few B vitamins and protozoan parasites but one section addresses vitamin D, Excerpt: “One way in which vitamin D3 might affect Plasmodium is through its involvement in phospholipid metabolism and signalling pathways 60. Vitamin D3 and analogues have pronounced inhibitory effects on P. falciparum erythrocytic late stage development possibly because the phospholipid biosynthesis pathways of the parasite is affected by these compounds 61. Inhibition of phospholipid biosynthesis by other classes of inhibitors (for instance choline analogues) has been followed up extensively 62, 63 and it is likely that these inhibitors will be developed as new drugs against malaria in the near future 64. Thus the activity of vitamin D3 analogues merits further attention.” [http://www.ncbi.nlm.nih.gov/pmc/articles/PMC2330093/]

Steroids. 1999;64:129–136. [PubMed] *Roughly this title could be translated into: Hormone D affects growth plate cartilage cells by affecting the endogenous cannabinoid system, — arachidonic acid and PGE2 can be formed from cannabinoids that are released from storage within cell membranes. Elevated levels of calcium intracellularly can be a trigger signalling the release of endogenous cannbinoids from the membranes.
7. Regulation of growth plate chondrocytes and bone cells, Excerpt: “In recent years it has been demonstrated that a large number of growth factors and cytokines regulate the proliferation and differentiation of bone and cartilage cells in vitro and in vivo (Table 2). This subject has been extensively reviewed (Goldring & Goldring, 1990; Canalis, McCarthy & Centrella, 1988a; Price & Russell, 1992; Martin, 1989). There is also increasing evidence that abnormal production of cytokines in diseases such as rheumatoid arthritis, osteoarthritis and osteoporosis may result in inappropriate responses by bone and cartilage cells. Those cytokines and growth factors considered to be of particular importance during bone development and growth include the IGFs, TGF a and b, bone morphogenetic proteins (BMPs), FGF, PDGF and epidermal growth factor (EGF). Many of the cell types present in the microenvironment of growing bone contribute to the local synthesis of cytokines and growth factors including the resident endothelial cells, marrow stromal cells, osteoblasts, periosteal cells and chondrocytes. The haemopoetic cells present in bone marrow include circulating monocytes, macrophages and T cells; these are another potential source of cytokines. In fact, several lines of evidence point to there being a close relationship between bone cells and cells of the immune system (Skjodt & Russell, 1993).”
7.12. Parathyroid hormone related peptide (PTHrP)
“PTHrP is a peptide closely related to PTH that is produced by normal tissues, with similar effects to PTH on bone. It has been established as having an important role in regulating the hypercalcaemia that is associated with some malignancies (Webb et al., 1988). PTHrP has also been identified as a fetal hormone which may regulate placental calcium (Ca2+) flux (Orloff, 1989). This peptide may also have an important role in skeletal development, having been localised in embryonic bone, and a recent study has shown that mice with a defective PTHrP gene have multiple skeletal abnormalities (Karaplis et al., 1992).” [http://archive.unu.edu/unupress/food2/UID06E/UID06E0V.HTM]

J Clin Invest. 1988 Nov; 82(5): 1798–1802 [http://www.ncbi.nlm.nih.gov/pmc/articles/PMC442751/] Abstract: “A parathyroid hormone-related protein (PTHrP) has recently been isolated from tumors associated with hypercalcemia. In the present study, we tested the effects of neutralizing antisera to the PTHrP on serum calcium and urine cAMP in two animal models of malignancy-associated hypercalcemia. The animal models consisted of (a) a human squamous cell lung cancer and (b) a human laryngeal cancer, both serially carried in athymic mice. The antisera specifically reduced the elevated serum calcium and urinary cAMP levels in the tumor-bearing animals. We conclude that PTHrP plays a major role in the pathogenesis of malignancy-associated hypercalcemia.”

“Parathyroid hormone-related peptide (PTHrP) has been detected in fetal serum and amniotic fluid. Using a combination of immunocytochemistry and molecular biology we have detected the peptide and its mRNA in a variety of fetal tissues throughout gestation. Tissue-specific mRNA isoforms were observed, the pattern of hybridization of which changed throughout gestation. In addition, the intensity and pattern of immunocytochemical localization of the peptide was found to vary over the time-period studied (8-30 weeks). PTHrP is expressed by a variety of tumours associated with the syndrome of humoral hypercalcaemia of malignancy and probably accounts for the hypercalcaemia by virtue of its limited amino acid homology with parathyroid hormone. These data demonstrate for the first time that PTHrP, a tumour-related peptide, is expressed during normal human fetal development, and suggest the possibility that it may function to regulate fetal calcium balance and growth in utero.”
- “Parathyroid hormone-related peptide (PTHrP) can be elevated in pregnant and lactating women and in newborn infants. Nonmalignant conditions that have been described in association with elevated plasma PTHrP levels include systemic lupus erythematosus, HIV-associated lymphadenopathy, lymphedema of chest or pleural cavities, and with benign tumors of the ovary, kidney and the neuroendocrine system.” [http://www.mayomedicallaboratories.com/test-catalog/Clinical+and+Interpretive/81774]
