The effects of tomato juice on male infertility.

Background And Objectives: This study aimed to investigate the effects of tomato juice consumption on seminal plasma lycopene levels and sperm parameters in infertile men.

Methods And Study Design: Subjects were male infertility patients with poor sperm concentration (<20×10 6/mL) and/or motility (<50%). Following a fourweek observation period, subjects were randomly assigned among three groups: a tomato juice group, an antioxidant group, and a control group.

Broccoli sprout extract induces detoxification-related gene expression and attenuates acute liver injury.

Aim: To investigate the effects of broccoli sprout extract (BSEx) on liver gene expression and acute liver injury in the rat.

Methods: First, the effects of BSEx on liver gene expression were examined. Male rats were divided into two groups.

Suppression effects of betaine-enriched spinach on hyperhomocysteinemia induced by guanidinoacetic acid and choline deficiency in rats.

Betaine is an important natural component of rich food sources, especially spinach. Rats were fed diets with betaine or spinach powder at the same level of betaine for 10 days to investigate the dose-dependent effects of spinach powder supplementation on hyperhomocysteinemia induced by guanidinoacetic acid (GAA) addition and choline deprivation. The GAA-induced hyperhomocysteinemia in rats fed 25% casein diet (25 C) was significantly suppressed by supplementation with betaine or spinach, and it was completely suppressed by taking 11.

6-shogaol, a major compound in ginger, induces aryl hydrocarbon receptor-mediated transcriptional activity and gene expression.

Xenobiotics are usually detoxified by drug-metabolizing enzymes and excreted from the body. The expression of many of drug-metabolizing enzymes is regulated by the aryl hydrocarbon receptor (AHR). Some substances in vegetables have the potential to be AHR ligands.

Establishment of a stable aryl hydrocarbon receptor-responsive HepG2 cell line.

The aryl hydrocarbon receptor (AHR) is a ligand-dependent transcription factor. It heterodimerizes with aryl hydrocarbon nuclear translocator, binds to the xenobiotic-responsive element (XRE), and enhances the transcription of genes encoding xenobiotic metabolizing enzymes. AHR also plays important roles in the inhibition of intestinal carcinogenesis and the modulation of gut immunity.
