Abstract EN
The hormone leptin has a variety of functions.
Originally known for its role in satiety and weight loss, leptin more recently has been shown to augment tumor growth in a variety of cancers.
Within gliomas, there is a correlation between tumor grade and tumor expression of leptin and its receptor.
This suggests that autocrine signaling within the tumor microenvironment may promote the growth of high-grade gliomas.
Leptin does this through stimulation of cellular pathways that are also advantageous for tumor growth and recurrence: antiapoptosis, proliferation, angiogenesis, and migration.
Conversely, a loss of leptin expression attenuates tumor growth.
In animal models of colon cancer and melanoma, a decline in the expression and secretion of leptin resulted in a reduction of tumor growth.
In these models, positive mental stimulation through environmental enrichment decreased leptin secretion and improved tumor outcome.
This review explores the link between leptin and glioblastoma.
