Abstract

Curcumin, the bioactive polyphenolic ingredient of turmeric, has been extensively studied for its effects on human papilloma virus (HPV) infection as well as primary and malignant squamous cervical cancers. HPV infections, especially those related to HPV 16 and 18 types, have been established as the leading cause of cervical cancer; however, there are also additional contributory factors involved in the etiopathogenesis of cervical cancers. Curcumin has emerged as having promising chemopreventive and anticancer effects against both HPV-related and nonrelated cervical cancers. In this review, we first discuss the biological relevance of curcumin and both its pharmacological effects and pharmaceutical considerations from a chemical point of view. Next, the signaling pathways that are modulated by curcumin and are relevant to the elimination of HPV infection and treatment of cervical cancer are discussed. We also present counter arguments regarding the effects of curcumin on signaling pathways and molecular markers dysregulated by benzo(a)pyrene (Bap), a carcinogen found in pathological cervical lesions of women who smoke frequently, and estradiol, as two important risk factors involved in persistent HPV-infection and cervical cancer. Finally, various strategies to enhance the pharmacological activity and pharmacokinetic characteristics of curcumin are discussed with examples of studies in experimental models of cervical cancer. © 2016 BioFactors, 43(3):331-346, 2017.

An essential role for NF-kappaB in preventing TNF-alpha-induced cell death.

A Beg, D Baltimore (1996)

Studies on mice deficient in nuclear factor kappa B (NF-kappaB) subunits have shown that this transcription factor is important for lymphocyte responses to antigens and cytokine-inducible gene expression. In particular, the RelA (p65) subunit is required for induction of tumor necrosis factor-alpha (TNF-alpha)-dependent genes. Treatment of RelA-deficient (RelA-/-) mouse fibroblasts and macrophages with TNF-alpha resulted in a significant reduction in viability, whereas RelA+/+ cells were unaffected. Cytotoxicity to both cell types was mediated by TNF receptor 1. Reintroduction of RelA into RelA-/- fibroblasts resulted in enhanced survival, demonstrating that the presence of RelA is required for protection from TNF-alpha. These results have implications for the treatment of inflammatory and proliferative diseases.

Prophylactic quadrivalent human papillomavirus (types 6, 11, 16, and 18) L1 virus-like particle vaccine in young women: a randomised double-blind placebo-controlled multicentre phase II efficacy trial.

Luisa Villa, Ronaldo L R Costa, Carlos Petta … (2005)

A randomised double-blind placebo-controlled phase II study was done to assess the efficacy of a prophylactic quadrivalent vaccine targeting the human papillomavirus (HPV) types associated with 70% of cervical cancers (types 16 and 18) and with 90% of genital warts (types 6 and 11). 277 young women (mean age 20.2 years [SD 1.7]) were randomly assigned to quadrivalent HPV (20 microg type 6, 40 microg type 11, 40 microg type 16, and 20 microg type 18) L1 virus-like-particle (VLP) vaccine and 275 (mean age 20.0 years [1.7]) to one of two placebo preparations at day 1, month 2, and month 6. For 36 months, participants underwent regular gynaecological examinations, cervicovaginal sampling for HPV DNA, testing for serum antibodies to HPV, and Pap testing. The primary endpoint was the combined incidence of infection with HPV 6, 11, 16, or 18, or cervical or external genital disease (ie, persistent HPV infection, HPV detection at the last recorded visit, cervical intraepithelial neoplasia, cervical cancer, or external genital lesions caused by the HPV types in the vaccine). Main analyses were done per protocol. Combined incidence of persistent infection or disease with HPV 6, 11, 16, or 18 fell by 90% (95% CI 71-97, p<0.0001) in those assigned vaccine compared with those assigned placebo. A vaccine targeting HPV types 6, 11, 16, 18 could substantially reduce the acquisition of infection and clinical disease caused by common HPV types.
