Pb2075: How Effective Are Leptin Gene Polymorphisms and Methylation During the Course of Multiple Myeloma (Mm)?

Abstract

Leptin is mainly produced from adipose tissue and released into the circulation. Circulating leptin binds to the leptin receptor (LEPR) in the brain, which activates signaling pathways that inhibit feeding and promote calorie expenditure. The leptin receptor (LEPR, also known as Ob-R) gene is located at 1p31. DNA methylation consists of addition a methyl group at position 5′ of the pyrimidine ring of the cytosines upstream of a guanine (dinucleotide CpG) catalyzed by DNA methyltransferases. Methylation of cytosine in CpG sites is an important epigenetic modification way that could suppress the gene expression.
