A prospective randomized controlled study of Mycobacterium Indicus Pranii vaccine, Measles Mumps Rubella vaccine and Vitamin D3 in extragenital cutaneous warts.
    Journal of cosmetic dermatology, 2023, Volume: 22, Issue:4

    Interventional, prospective, four arm randomized control.. Outpatient department, Department of Dermatology, Venereology and Leprology, AIIMS Jodhpur (Rajasthan), India.. Two hundred patients.. The intervention administered in the groups were normal saline (A), vitamin D. A total of 197 patients were recruited. The mean percentage improvement in the injected and non-injected warts was 68.4% and 66.8%, respectively. Intention to treat analysis (ITT) showed that complete clearance of lesions in injected wart occurred in placebo, vit D. The efficacy of immunotherapies was comparable to placebo with minimal side effects.

Effects of dietary calcium and vitamin D3 on tumor promotion in mouse skin.
    Nutrition and cancer, 1991, Volume: 16, Issue:3-4

    The effects of low, adequate, and supplemental intake of calcium and vitamin D3 on 12-O-tetradecanoylphorbol-13-acetate (TPA) skin tumor promotion were examined. Administration of the experimental diets was started one week before the first TPA application to the 7,12-dimethylbenz[a]anthracene-initiated dorsal skin of female Sencar mice. Neither dietary calcium in a range from 0.15% to 2.0% of the diet as calcium carbonate nor vitamin D3 ranging from 200 to 4,000 IU/kg diet resulted in modulation of the skin papilloma response in terms of incidence, number per mouse, or size distribution of tumors. There were also no effects of the varied levels of calcium or vitamin D3 on mouse body weights, serum calcium, or TPA induction of epidermal ornithine decarboxylase activity. These results indicate that dietary administration of a wide range of doses of calcium or vitamin D does not alter the serum calcium levels and, therefore, does not appear capable of altering skin tumor promotion. These results are in contrast to reports that demonstrate antineoplastic activity for both calcium ion and active hormonal vitamin D, either in control of epidermal cell proliferation and/or differentiation or inhibition of carcinogenesis.

Induction of metallothionein mRNA by tumor promoters in mouse skin and its constitutive expression in papillomas.
    Molecular carcinogenesis, 1989, Volume: 2, Issue:2

    A single topical application of 12-O-tetradecanoylphorbol-13-acetate (TPA) was found to induce mRNA of a metallothionein (MT) gene or genes in the skin of Sencar mice, and papillomas produced by repeated applications of TPA were shown to have elevated levels of MT mRNA. Induction of MT mRNA was maximal 4-8 h after application of TPA and returned to the control level 24 h later. A dose-dependent increase of MT mRNA was observed with doses of TPA of 1-5 micrograms. Of the other promoters tested, phorbol-12, 13-didecanoate, mezerein, and the ionophore A23187 also induced MT mRNA, but 4-O-methyl-TPA and benzoyl peroxide did not. Phorbol and 4 alpha-phorbol-12,13-didecanoate, which are not promoters, also did not induce MT mRNA. Retinoic acid and 1 alpha, 25-dihydroxyvitamin D3, inhibitors of tumor promotion, did not induce MT mRNA themselves or inhibit the induction of MT mRNA by TPA. In C57BL/6 promotion-resistant mice, TPA caused only slight induction of MT mRNA. These data suggest a correlation between induction of MT mRNA and epidermal hyperplasia. The constitutive elevation of MT mRNA levels in papillomas may be due to the loss, during the process of tumor promotion, of some mechanism regulating MT gene expression.
