Does soy really raise estrogen levels?
Soy is unique in that it contains a high concentration of isoflavones, a type of plant estrogen (phytoestrogen) that is similar in function to human estrogen but with much weaker effects. Soy isoflavones can bind to estrogen receptors in the body and cause either weak estrogenic or anti-estrogenic activity.
Does lycopene increase estrogen?
Previous studies have shown that the dietary carotenoids including lycopene inhibits the estrogen signaling of 17-β E2. Lycopene and other carotenoids inhibited estrogen-induced transactivation of estrogen response element (ERE) that was mediated by both ER-α and ER-β.
Can tofu affect hormones?
Research suggests that eating soy products might decrease FSH and LH in people who are premenopausal, which may impact fertility. And it might increase estrogen in people who are menopausal (19), leading to a reduction in menopausal symptoms.

¿Qué es la fase M de la célula?
Una vez el material genético está duplicado, la célula pasa a la fase G2. Durante esta fase la célula sigue creciendo y termina de sintetizar los componentes que necesita. Luego llega a la fase M, cuando la célula finalmente se divide. A partir de una célula se obtienen dos células hijas, cada una de las cuales empieza su fase G1,
¿Qué es la fase G1 de la ciclina?
En la fase G1 hay altos niveles de la ciclina D, que se une a CDK4 y CDK6. Luego van subiendo los niveles de ciclina E, cuando llegan al máximo se produce la transición a la fase S. La ciclina E se une a la CDK2.
¿Cómo se regula la progresión en el ciclo celular?
La progresión en el ciclo celular está regulada por la acción de las proteínas CDKs, que son quinasas dependientes de ciclinas, y por las ciclinas. Las quinasas son proteínas que se encargan de fosforilar determinados sustratos, como otras proteínas.
¿Qué es la fase M del ciclo celular?
L a fase M es la fase del ciclo celular donde se produce la división de una célula en dos células hijas.Comprende una serie de procesos en paralelo encaminados a repartir los componentes celulares, sintetizados durante las fases anteriores del ciclo celular, entre las dos células hijas resultantes de una forma generalmente equitativa.
