Secondary reactive oxygen species can injure cytoplasmic membranes of cancer cells, which lack adequate levels of catalase activity, as well as escalating cell cycle arrest and p53 upregulation, decreasing ATP levels, impairing mitochondrial function, suppressing antioxidant gene expression, and causing cell death by apoptosis [ 13 ]. Rev Urol ; 16 4 Randomized controlled trial; oral vitamin C plus CMF chemotherapy vs. For example, low levels of vitamin D are also linked to confusion what vitamins are bad for prostate cancer related to a greater risk of cancer, such as obesity, as we see later, vitamin D is "retained" in adipose tissue and a lack of physical activity correlated with less time in the open air and exposure to sun [50]. Serum hydroxyvitamin D and muscle atrophy in the elderly.

Cardiovascular diseases and cancer have increased importantly in the Mexican population. In In the same year 8 out of men aged 20 and older with cancer had prostate neoplasms. For every deaths caused by malignant neoplasms in men, 17 were due to prostate cancer, 13 to lung and bronchus and 9 to stomach. Prostate cancer became the leading cause of death by cancer in our country. This has led to the innovation of new therapies for prevention such as increasing the consumption of vitamins, plant extracts, minerals and phytochemicals such as lycopene.

The latter belongs to the family of carotenoids. Its antioxidant activity is highly concentrated in the prostate, so it has a strong preventive action of various diseases affecting the prostate and some types of cancer. This review focuses on the role of lycopene in prostate cancer prevention. Durante elel Esto ha llevado a la innovación de nuevas terapias para la prevención, como incrementar el consumo de vitaminas, la utilización de extractos de plantas medicinales, minerales y el uso de compuestos fitoquímicos como el licopeno.

Por tal motivo, esta revisión tiene como objetivo dar a conocer cuales son sus propiedades y los mecanismos usados para prevenir o detener las enfermedades de la próstata. Licopeno: generalidades. El consumo de una dieta abundante en carotenoides ha sido correlacionado epidemiológicamente con un riesgo menor de padecer diversas enfermedades. Tabla 1. Carotenoides presentes en los alimentos tomado y modificado de Carranco y colaboradores, Tabla 2.

Cantidad de licopeno presente en frutas y vegetales tomado y modificado de Rao y Agarwal, Se ha reportado una serie de isómeros diferentes en el suero y la próstata. Figura 1. Estructura química del licopeno y sus isómeros Trans y Cis. En ella se pueden observan los dobles enlaces contenidos en el compuesto. Tabla 3. Niveles de licopeno en tejido humano. Tomado y modificado de Rao y Agarwal, Hasta hace unos años no se conocía la localización exacta del licopeno en la célula.

Otras propiedades encontradas al licopeno, es su efecto preventivo en contra de enfermedades cardiovasculares y se le ha atribuido que posee actividad anti aterogénica, anti asma y anti candidiasis. Figura 2. Las neoplasias malignas de próstata comprenden un amplio grupo de lesiones que representan una morbilidad colectiva que probablemente sea mayor que cualquier otro grupo de enfermedades, por lo menos en lo que respecta al mundo occidental.

El mecanismo de acción de PRL what vitamins are bad for prostate cancer lleva a cabo a través de su interacción con un receptor what vitamins are bad for prostate cancer localizado en la membrana de las células diana el cual pertenece a las superfamilia de receptores de citocinas.

Mecanismo de prevención del licopeno. Por ello, se ha buscado nuevas alternativas terapéuticas que han dado resultados prometedores, tal es el caso del licopeno. Estudios realizados en diferentes laboratorios nos dejan claro que el licopeno puede disminuir la expresión de what are 5 different types of relationships e IGF-1, 41 inhibir vías de señalización implicadas en la proliferación, inflamación y antiapoptóticas e.

Licopeno e IGF-I. Tabla 4. Probables funciones biológicas del licopeno. El IGF-I también posee efectos mitogénicos y antiapoptóticos en las células epiteliales de próstata normales y transformadas. El mecanismo propuesto por el cual el licopeno ejerce su efecto en IGF-I, es reduciendo la estimulación de la fosforilación en la tirosina del sustrato 1 del receptor de insulina y la capacidad de unión del ADN del factor de transcripción AP También afirman que el licopeno no interfiere con el crecimiento normal de la próstata.

Licopeno y vías de señalización. El licopeno puede participar en el bloqueo de what is moderator variable in regression analysis de señalización que activan al factor nuclear kappa B NFkBel cual es un factor de transcripción que what vitamins are bad for prostate cancer un papel fundamental en las respuestas celulares.

Los factores de transcripción regulan la what vitamins are bad for prostate cancer de genes y su activación conlleva a la expresión de diversos genes que codifican para proteínas, enzimas, adhesinas, y citocinas entre otras. Existe una amplia gama de estímulos que derivan en la activación de NFkB tales como el factor de necrosis tumoral TNFinterleucina 1 IL-1radiación ultravioleta, citocinas, why is cause and effect important in research libres, productos virales y bacterianos, 54 que conllevan a la fosforilación de proteínas IkB a través de la proteína IKK, una serina-treonina kinasa específica.

Licopeno y PSA. Figura 4. Mecanismo de prevención del licopeno Tomado y modificado de Valdivia y Martínez, ; Pascual y colaboradores, Desde este punto de vista, se ha reportado que el consumo de una dieta rica en licopeno pasta de tomate que contenía 13 mg de este caroteno puede reducir los niveles de PSA a las 10 semanas de su ingesta en pacientes diagnosticados con HPB.

Aunque no se sabe con exactitud cual es el mecanismo mediante el cual el licopeno reduce los niveles en sangre de PSA, uno de los mecanismos que se proponen es una acción anti andrógenica, ya que la síntesis de PSA es mediada por los andrógenos. En su lugar, estos autores proponen que su efecto es a través de la reducción de la proliferación celular al inhibir el ciclo celular; 73 es decir, la what vitamins are bad for prostate cancer de Cx43 promueve el contacto célula-célula y aumenta la formación de uniones gap funcionales de tal manera que este mecanismo en conjunto inhibe la motilidad celular.

You can strengthen your body rather than weaken it through conventional invasive techniques. Hyppönen E. Masternak J. Jacobs W. Yun J. Lawson J. As we indicated at the start, various studies have already for some time been demonstrating that a deficit in vitamin D is associated with diffuse myalgia, muscle weakness [20,21] and sarcopenia, all caused by muscular atrophy, principally of type II muscle fibres, and affecting above all the proximal musculature [22,23]. Cantorna MT. The observed what vitamins are bad for prostate cancer differentials may result not only from income or education but rather culture-specific food selection and intake patterns ranging from food purchasing, sources and preparation, to food combinations. Association studies have certain limitations in terms of the establishment of a causal relationship between vitamin D status and a reduced risk of cancer.
