Fibroblasts maintained in 3 dimensions show a better differentiation state and higher sensitivity to estrogens.

Cell differentiation and response to hormonal signals were studied in a 3D environment on an in-house generated mouse fibroblast cell line expressing a reporter gene under the control of estrogen responsive sequences (EREs). 3D cell culture conditions were obtained in a Rotary Cell Culture System; (RCCS™), a microgravity based bioreactor that promotes the aggregation of cells into multicellular spheroids (MCS). In this bioreactor the cells maintained a better differentiated phenotype and more closely resembled in vivo tissue.

Effect of biological and chemical oxidation on the removal of estrogenic compounds (NP and BPA) from wastewater: an integrated assessment procedure.

A major source of the wide presence of EDCs (Endocrine Disrupting Compounds) in water bodies is represented by direct/indirect discharge of sewage. Recent scientific literature reports data about their trace concentration in water, sediments and aquatic organisms, as well as removal efficiencies of different wastewater treatment schemes. Despite the availability of a huge amount of data, some doubts still persist due to the difficulty in evaluating synergistic effects of trace pollutants in complex matrices.

MAK-4 and -5 supplemented diet inhibits liver carcinogenesis in mice.

Background: Maharishi Amrit Kalash (MAK) is an herbal formulation composed of two herbal mixtures, MAK-4 and MAK-5. These preparations are part of a natural health care system from India, known as Maharishi Ayur-Veda. MAK-4 and MAK-5 are each composed of different herbs and are said to have maximum benefit when used in combination.

Genistein accumulates in body depots and is mobilized during fasting, reaching estrogenic levels in serum that counter the hormonal actions of estradiol and organochlorines.

Isoflavones are important dietary compounds that are consumed with the daily diet and elicit important biological actions. Here we report on the ability of genistein to partially accumulate in body depots of male mice, be released following fasting, and modulate the actions of estradiol and environmental estrogens in reproductive and nonreproductive target organs of estrogen-reporter mice (ERE-tK-luciferase). After the consumption of 50 mg/kg/day for 3 days, genistein accumulates in body compartments where it remains at functionally active levels for at least 15 days.
