ABSTRACT

ETHNOPHARMACOLOGICAL RELEVANCE: Leonurus japonicus Houtt (L. japonicus, Chinese motherwort), known as Yi Mu Cao which means "good for women", has long been widely used in China and other Asian countries to alleviate gynecological disorders, often characterized by estrogen dysregulation. It has been used for the treatment of polycystic ovary syndrome (PCOS), a common endocrine disorder in women but the underlying mechanism remains unknown. AIM OF THE STUDY: The present study was designed to investigate the effect and mechanism of flavonoid luteolin and its analog luteolin-7-methylether contained in L. japonicus on aromatase, a rate-limiting enzyme that catalyzes the conversion of androgens to estrogens and a drug target to induce ovulation in PCOS patients. MATERIALS AND METHODS: Estrogen biosynthesis in human ovarian granulosa cells was examined using ELISA. Western blots were used to explore the signaling pathways in the regulation of aromatase expression. Transcriptomic analysis was conducted to elucidate the potential mechanisms of action of compounds. Finally, animal models were used to assess the therapeutic potential of these compounds in PCOS. RESULTS: Luteolin potently inhibited estrogen biosynthesis in human ovarian granulosa cells stimulated by follicle-stimulating hormone. This effect was achieved by decreasing cAMP response element-binding protein (CREB)-mediated expression of aromatase. Mechanistically, luteolin and luteolin-7-methylether targeted tumor progression locus 2 (TPL2) to suppress mitogen-activated protein kinase 3/6 (MKK3/6)-p38 MAPK-CREB pathway signaling. Transcriptional analysis showed that these compounds regulated the expression of different genes, with the MAPK signaling pathway being the most significantly affected. Furthermore, luteolin and luteolin-7-methylether effectively alleviated the symptoms of PCOS in mice. CONCLUSIONS: This study demonstrates a previously unrecognized role of TPL2 in estrogen biosynthesis and suggests that luteolin and luteolin-7-methylether have potential as novel therapeutic agents for the treatment of PCOS. The results provide a foundation for further development of these compounds as effective and safe therapies for women with PCOS.

ABSTRACT

La osteoporosis y las enfermedades cardiovasculares son patologías prevalentes en mujeres posmenopáusicas. La calcificación vascular es un proceso en el que se produce una distorsión de la arquitectura natural del tejido arterial con una transformación símil osteogénica. La fisiología vascular y la osteogénesis (formación y remodelación ósea) comparten una complejidad metabólica y funcional crítica, que ha sido poco explorada en forma conjunta, lo que ha impulsado la concepción del Eje Óseo-Vascular como nueva área de investigación, con una visión de estudio integradora con la finalidad de identificar vínculos entre ambos sistemas. En virtud de la controversia planteada sobre los riesgos/beneficios de la terapia de reemplazo hormonal para prevenir enfermedades asociadas a la menopausia, se ha incentivado la búsqueda de nuevas opciones de tratamiento. Los fitoestrógenos, como compuestos nutracéuticos, surgen como una potencial alternativa terapéutica. En particular, las isoflavonas presentan gran analogía estructural con el estrógeno humano 17ß-estradiol, lo que les permite unirse al receptor de estrógenos e inducir acciones estrogénicas tanto en células animales como humanas. Basado en la experiencia propia como en lo reportado en la bibliografía, este artículo analiza la información disponible sobre las acciones vasculares y óseas de los fitoestrógenos (específicamente la isoflavona genisteína), con una visión de ciencia traslacional. Es de esperar que los avances en el conocimiento derivado de la ciencia básica, en un futuro cercano, pueda contribuir a decisiones clínicas a favor de promover terapias naturales de potencial acción dual, para la prevención de enfermedades de alta prevalencia y significativo costo social y económico para la población. (AU)


Osteoporosis and cardiovascular diseases are prevalent diseases in postmenopausal women. Vascular calcification is a cellmediated process that leads to the loss of the natural architecture of the arterial vessels due to osteogenic transdifferentiation of smooth muscle cells, and matrix mineralization. Vascular physiology and osteogenesis (bone formation and remodeling) share a critical metabolic and functional complexity. Given the emerging integrative nature of the bonevascular axis, links between both systems are a matter of ongoing interest. In view of the controversy stated about the risks/benefits of hormone replacement therapy to prevent diseases associated with menopause, phytoestrogens arise as a potential natural therapeutic alternative. In particular, isoflavones have a strong structural analogy with the human estrogen 17ß-estradiol, that allows them to bind to the estrogen receptor and induce estrogenic actions in animal and human cells. Based in on our own experience and the information available in the literature, in this paper we provide an overview of the role of phytoestrogens on vascular and bone tissues, with focus on Genistein actions. We wish that the basic knowledge acquired may contribute to guide clinical decisions for the promotion of natural therapies for the treatment of diseases that conspire against human health. (AU)

ABSTRACT

El resveratrol es un polifenol natural presente en numerosas plantas y frutos como cacahuetes, moras, arándanos y, sobre todo, en la uva y el vino tinto. Su síntesis está condicionada por la presencia de factores estresantes, tales como la contaminación fúngica o la radiación ultravioleta. En las plantas actúa como fitoalexina, es decir, posee la capacidad de inhibir el progreso de ciertas infecciones. La medicina antigua ha utilizado extractos de plantas que contienen resveratrol desde hace más de 2.000 años y hace más de 30 años que se aisló y se comenzaron a estudiar sus propiedades con métodos científicos. Sus propiedades in vitro han sido ampliamente estudiadas y contrastadas, entre ellas cabe destacar su actividad como anticancerígeno, antiagregante plaquetario, antiinflamatorio, antialérgico, etc. En cuanto a sus propiedades in vivo su actividad no está tan clara; existen numerosos estudios que encuentran beneficios sobre el sistema cardiovascular, enfermedades como la diabetes y sobre la longevidad; sin embargo, otros autores no encuentran una equivalencia de los estudios in vitro a in vivo. Esta discrepancia es debida a la biodisponibilidad que tiene el resveratrol. Tras un consumo oral se ha comprobado que la absorción es muy buena, pero las vías metabólicas dejan solo una pequeña fracción de resveratrol libre en sangre, por lo que la disponibilidad en los tejidos diana es muy baja y no se llegan a las concentraciones empleadas en los estudios in vitro. Así pues, aunque los estudios in vitro indican que se trata de una molécula biológicamente activa con propiedades saludables, los estudios realizados in vivo hasta el momento no pueden confirmar parte de estos resultados, lo cual puede atribuirse a su baja biodisponibilidad(AU)


Resveratrol is a natural polyphenol which can be found in many plants and fruits, such as peanuts, mulberries, blueberries and, above all, in grapes and red wine. Its synthesis is regulated by the presence of stressful factors, such as fungal contamination and ultra-violet radiation. In plants, it plays a role as a phytoalexin, showing a capacity to inhibit the development of certain infections. Plant extracts which contain resveratrol have been employed by traditional medicine for more than 2000 years. Resveratrol was first isolated, and its properties were initially studied with scientific methods, thirty years ago. Its in vitro properties have been extensively studied and demonstrated. It is worth highlighting its activity as an anti-cancer agent, platelet anti-aggregation agent, anti-inflammatory, antiallergenic, etc. The activity of its in vivo properties are not so clear. There are many studies that report benefits on the cardiovascular system, illnesses such as diabetes, and in longevity. However, other authors did not find any agreement between in vitro and in vivo studies. This discrepancy is due to the bioavailability of resveratrol. After an oral dose, it has been demonstrated that the absorption is very high, but the metabolic pathways leave just a little free resveratrol in blood, therefore the bioavailability in the target tissues is very low and the concentrations used in in vitro studies are not found in these tissues. Thus, resveratrol is a very active molecule for maintaining health, but due to the low bioavailability not all the in vitro effects can be translated to in vivo. This opens a new potential approach, seeking derivatives of resveratrol that can be measured in the desired tissues(AU)

ABSTRACT

La enzima P450 aromatasa (P450Aro) participa en la síntesis de estrógenos a partir de andrógenos. La mutación c655G>A, descripta en forma heterocigota en una niña y en forma homocigota en un hombre adulto, ambos con déficit de aromatasa, genera la disrupción del sitio dador de splicing exón5-intrón5. Se ha postulado que la retención del intrón5 y la generación de una proteína truncada inactiva serían las consecuencias de esta mutación. Sorpresivamente, la paciente presentó desarrollo espontáneo de mamas y niveles puberales de estradiol, sugiriendo una actividad aromatasa (AA) residual. En principio postulamos que la mutación c655G>A generaría la pérdida del exón5 con conservación del marco de lectura, generándose una proteína con menor actividad que podría explicar el déficit parcial. La expresión del ARNm sin exón5 (ARNm- E5) en linfocitos de la paciente sugiere una asociación entre la pérdida del exón y la presencia de la mutación; posteriormente confirmada realizando ensayos de splicing en células Y1. Sin embargo, la expresión del cDNAE5 en células Y1 presentó una AA nula que no explicaría un déficit parcial. La expresión del ARNm-E5 fue detectada en placenta, testículo y adrenal humanos como una variante de splicing normal. Estos resultados indicarían la ocurrencia de splicing alternativo (SA) en la zona codificante de P450Aro como un posible mecanismo regulador de la producción de estrógenos en tejidos esteroidogénicos humanos. La mutación c655G>A podría alterar los mecanismos fisiológicos reguladores del SA del exón5 favoreciendo su exclusión. De esta forma, bajos niveles de ARNm+E5 podrían expresarse aun en presencia de la mutación explicando el fenotipo de déficit parcial observado en la paciente.


P450 aromatase (P450Aro), involved in androgen to estrogen conversion, is encoded by the CYP19 gene. P450Aro c655G>A mutation described in heterozygous form in a girl and in homozygous form in an adult male with P450Aro deficiency results in an aberrant splicing due to disruption of a donor splice site. A truncated inactive protein would be expected if intron5 is retained. Surprisingly, the girl described with this mutation showed spontaneous breast development and pubertal estradiol (E2) levels suggesting residual P450Aro activity (AA). Formerly, we postulate the in frame E5 skipping as a consequence of this mutation generating a protein with some degree of activity. When P450Aro mRNA expression was analysed from patient's lymphocytes, an aberrant spliced mRNA lacking E5 (-E5mRNA) was detected, suggesting an association between E5 skipping and the presence of the mutation. Splicing assays in Y1 cells confirmed this association. -Ex5 cDNA expression in Y1 cells resulted in an inactive protein that could not explain patient's phenotype. Exon 5 might be predicted as a poorly defined exon suggesting a susceptibility to splicing mutations and physiological alternative splicing (AS) events. Therefore, -Ex5mRNA was assessed as a natural occurring alternative transcript in normal human steroidogenic tissues. As P450Aro -E5mRNA expression was detected in human term placenta, prepubertal testis and prepubertal adrenal, we might speculate that AS of P450Aro coding region would occur in humans and would be involved in the complex AA regulation. Furthermore, tissue specific regulation of AS might suggest low expression of +E5mRNA from the c655G>A allele explaining residual AA evidenced in the affected girl.

ABSTRACT

The mammalian testis serves two main functions: production of spermatozoa and synthesis of steroids; among them estrogens are the end products obtained from the irreversible transformation of androgens by a microsomal enzymatic complex named aromatase. The aromatase is encoded by a single gene (cyp19) in humans which contains 18 exons, 9 of them being translated. In rats, the aromatase activity is mainly located in Sertoli cells of immature rats and then in Leydig cells of adult rats. We have demonstrated that germ cells represent an important source of estrogens: the amount of P450arom transcript is 3-fold higher in pachytene spermatocytes compared to gonocytes or round spermatids; conversely, aromatase activity is more intense in haploid cells. Male germ cells of mice, bank voles, bears, and monkeys express aromatase. In humans, we have shown the presence of a biologically active aromatase and of estrogen receptors (alpha and ß) in ejaculated spermatozoa and in immature germ cells in addition to Leydig cells. Moreover, we have demonstrated that the amount of P450arom transcripts is 30 percent lower in immotile than in motile spermatozoa. Alterations of spermatogenesis in terms of number and motility of spermatozoa have been described in men genetically deficient in aromatase. These last observations, together with our data showing a significant decrease of aromatase in immotile spermatozoa, suggest that aromatase could be involved in the acquisition of sperm motility. Thus, taking into account the widespread localization of aromatase and estrogen receptors in testicular cells, it is obvious that, besides gonadotrophins and androgens, estrogens produced locally should be considered to be physiologically relevant hormones involved in the regulation of spermatogenesis and spermiogenesis.

ABSTRACT

O uso do álcool entre mulheres é uma questão atual e preocupante, face a maior vulnerabilidade destas aos danos hepáticos, cerebrais, entre outros, quando comparadas aos homens com padrões semelhantes de consumo.Sendo assim, investigaram-se as possíveis variações na farmacocinética do etanol em mulheres, considerando duas fases do ciclo menstrual (pré-folicular e lútea), bem como o uso de anticoncepcionais orais (AO). Participaram voluntários dos sexos feminino (n=22) e masculino (n=14), administrando-lhes 0,3 g/kg de etanol, na forma de uísque. Os resultados indicaram: a) os parâmetros farmacocinéticos do etanol não variam em função do ciclo menstrual (fase pré-folicular e lútea); b) as mulheres que tomavam (AO)...

ABSTRACT

Los lisosomas no deben considerarse sólo orgánulos que participan en la lisis de diferentes moléculas en proceso de digestión o defensa celular, ya que participan en diversos procesos de metabolismo celular, incluyendo los regulados hormonales. La actividad lisosomal se ve alterada minutos después de la administración de hormonas tanto esteroides como peptídicas incluyendo efectos como: labilización de membranas, cambio en la estructura química de las hidrolasas (latencia estructural) y migración perinuclear de lisosomas. Estas alteraciones demuestran que la actividad lisosomal es hormino-dependiente, y que hidrolasas como fosfatasa ácida pueden esta actuando de alguna manera a nivel de des-represión génica. Por otro lado, los lisosomas pueden propagar efectos hormonales desde la superficie de las células blanco hasta el núcleo. Es muy probable que ésta propagación se efectúe por medio de poblaciones especializadas de lisosomas que bajo el efecto hormonal migran a la región perinuclear. Se ha demostrado que ciertas substancias naturales y sintéticas que estabilizan membranas pueden bloquear esos eventos de distinto grado, de tal manera, que estos restablecen la labilización lisosomal y por consiguiente impiden la liberación enzimática. De una u otra forma, por lo anteriormente descrito, el sistema lisosomal participa en los mecanismos de comunicación autocrina, paracrina y endocrina

ABSTRACT

Existen hipótesis en el sentido de que el estatus hormonal está involucrado en la distinta susceptibilidad entre el hombre y la mujer en el desarrollo de enfermedad hepatobiliar, ya que el hígado es órgano blanco para hormonas esteroides. En el desarrollo del fenómeno fibrogénico durante la cirrosis hepática de diversa etiología están involucradas las células de Ito, los miofibroblastos y diversas citocinas como factor transformador de crecimiento-ß, interleucina-6 y factor de necrosis tumoral-alfa. Se sabe que en el organismo existen asas de regulación mutua entre citocinas, glucocorticoides y esteroides sexuales; en el hígado, esta interacción pudiera afectar el proceso fibrogénico a través de diferenciación de células de Ito. El conocimiento del papel preciso de los glucocorticoides y las hormonas esteroides sexuales sobre los mecanismos fibrogénicos, permitiría sustentar racionalmente la viabilidad de la manipulación hormonal en el tratamiento de padecimiento hepático de natulareza fibrótica

ABSTRACT

De los estudios realizados en embriones preimplantados de mamíferos, llama la atención su capacidad endócrina para sintetizar hormonas esteroides: progesterona, progestinas y diversos estrógenos, los cuales efectuan localmente las propiedades del oviducto y del endometrio para crear un entorno apropiado para su nutrición, migración y desarrollo que permita su implantación en el útero materno. Entre los esteroides secretados por el embrión, los estrógenos son de un interés especial debido a su importancia potencial en los eventos bioquímicos asociados con el proceso de implantación. El propósito de este artículo es contribuir el conocimiento de la biosíntesis y metabolismo estrogénico por el embrión preimplantado.
