Genistein Supplementation Affects Mineral Homeostasis in Rats with Mammary Cancer

Area of Science:

• Biochemistry
• Toxicology
• Oncology

Background:

• Mammary gland neoplasia is a significant health concern.
• Genistein, a soy isoflavone, has been studied for its potential anti-cancer properties.
• The impact of different genistein forms on mineral homeostasis during cancer is not fully understood.

Purpose of the Study:

• To investigate the effects of nano, micro, and classic genistein on macroelement (calcium, magnesium, potassium, sodium) levels in rat organs.
• To assess these effects in the context of chemically induced mammary gland cancer.

Main Methods:

• Thirty-two rats were divided into four groups: control and three supplemented with different genistein forms (nano, micro, classic).
• Mammary gland cancer was induced using 7,12-dimethylbenz[a]anthracene (DMBA).
• Macroelement content in kidneys, brains, hearts, livers, spleens, and femurs was analyzed.

Main Results:

• Genistein supplementation significantly altered macroelement content across various organs.
• Soft tissue calcification, primarily due to calcium accumulation, was observed in multiple organs (brain, heart, liver, spleen, femurs).
• Calcium accumulation varied by genistein form and tissue, with nanogenistein showing notable effects on spleen and femurs.

Conclusions:

• Genistein supplementation, irrespective of its form, impacts mineral homeostasis in rats with induced mammary cancer.
• The observed calcifications highlight potential risks associated with genistein use during neoplastic conditions.
• Further research is needed to elucidate the precise mechanisms and clinical implications.
