ABSTRACT

Objective:

κ-carrageenan is a food stabilizer agent which has an antiproliferative effect, while vitamin D is a prohormone acts on the nuclear receptor and has a cytotoxic against cancer. This study aimed to show the synergistic effect of using topical κ-carrageenan and oral administration of the vitamin D on the 7, 12-dimethylbenz[a] anthracene (DMBA)-induced oral cancer. Material and

Methods:

fifty four male albino rats were randomly divided into seven groups Acetonetreated served as control (Group I), vitamin D (5000UI)-treated (Group II), κ-carrageenan (1%)- treated (Group III), DMBA (0.5%)-treated (Group IV), Acetone, κ-carrageenan and DMBA were administered topically on both cheeks and palate, five times weekly for 12 weeks, while the vitamin D was administered orally twice weekly for 12 weeks. Groups V, VI, and VII were animals treated with vitamin D, κ-carrageenan, and both vitamin D and κ-carrageenan for 8 weeks after induction of oral cancer. At the end of the study, blood samples were obtained by cardiac puncture for determination of TNF-α and EGFR.

Results:

In the groups III and IV, serum EGFR showed significant low levels compared with Group I. In the Group VII, serum EGFR showed a significantly (p=0.014) low level compared with Group IV (614.3±69.7 pg/ml versus 882.4±45.6 pg/ml, respectively). Higher percentages of high levels of TNF-α were observed in the Groups VI and VII, while a lower percentage of EGFR was observed in the Group VI.

Conclusion:

both κ-carrageenan and vitamin D have antiproliferative effect against DMBAinducing oral cancer by increasing the levels of TNF-α and suppressing the signaling pathway of EGFR. Concomitant using κ-carrageenan and vitamin D reduces the antiproliferative effect of each other.(AU)
RESUMO

Objetivo:

κ-carragenina é um agente estabilizador de alimentos que tem efeito um antiproliferativo, enquanto a vitamina D é um pró-hormônio que atua sobre o receptor nuclear e possui efeito citotóxico contra o câncer. Este estudo teve como objetivo mostrar o efeito sinérgico do uso de κ-carragenina tópica e administração oral da vitamina D no câncer de boca induzido por 7, 12-dimetilbenz[a]antraceno (DMBA). Material e

Métodos:

cinquenta e quatro ratos albinos machos foram divididos aleatoriamente em sete grupos tratado com acetona como controle (Grupo I), tratado com vitamina D (5000UI) (grupo II), tratado com κ-carragenina (1%) (grupo III), DMBA (0,5%) tratado (Grupo IV), acetona, κ-carragenina e DMBA foram administrados topicamente nas bochechas e no palato, cinco vezes por semana durante 12 semanas, enquanto a vitamina D foi administrada por via oral duas vezes por semana durante 12 semanas. Os grupos V, VI e VII foram animais tratados com vitamina D, κ-carragenina e No final do estudo, foram obtidas amostras de sangue por punção cardíaca para determinação do TNF-α e EGFR.

Resultados:

Nos grupos III e IV, o EGFR sérico mostrou níveis baixos significativos em comparação com o Grupo I. No grupo VII, o EGFR sérico mostrou um nível significativamente baixo (p = 0,014) em comparação com o Grupo IV (614,3 ± 69,7 pg / ml versus 882,4 ± 45,6 pg / ml, respectivamente). Maiores porcentagens de TNF-α foram observadas nos Grupos VI e VII, enquanto uma menor porcentagem de EGFR foi observada no Grupo VI.

Conclusão:

Tanto a κ-carragenina quanto a vitamina D têm efeito antiproliferativo contra o câncer de boca induzido por DMBA aumentando os níveis de TNF-α e suprimindo a via de sinalização do EGFR. O uso concomitante de κ-carragenina e a vitamina D reduz o efeito antiproliferativo um do outro (AU)
