BACKGROUND The incidence of obesity has risen dramatically over the last few decades. This epidemic may be affected by exposure to xenobiotic chemicals. Bisphenol A (BPA), an endocrine disruptor, is detectable at nanomolar levels in human serum worldwide. Adiponectin is an adipocyte-specific hormone that increases insulin sensitivity and reduces tissue(More)
New information about the effects of prolactin (PRL) on metabolic processes warrants re-evaluation of the overall metabolic actions of PRL. PRL affects metabolic homeostasis by regulating key enzymes and transporters that are associated with glucose and lipid metabolism in several target organs. In the lactating mammary gland, PRL increases the production(More)
Bisphenol A (BPA) is one of the most prevalent and best studied endocrine disruptors. After years of exposure to consumer products containing BPA, most individuals tested have circulating BPA at the low nanomolar levels. In addition to its well documented actions on the reproductive system, BPA exerts a wide variety of metabolic effects. This review(More)
Breast and prostate cancers are hormone-sensitive malignancies that afflict millions of women and men. Although prolactin (PRL) is known as a survival factor that supports tumor growth and confers chemoresistance in both cancers, its precise role in these tumors has not been studied extensively. Growth hormone and placental lactogen also bind PRL receptor(More)
The proinflammatory status of adipose tissue has been linked to the metabolic and cardiovascular consequences of obesity. Human adipose cells express the calcium sensing receptor (CaSR), and its expression is elevated in inflammatory states, such as that associated with obesity. Given the CaSR's association with inflammation in other tissues, we evaluated(More)
INTRODUCTION Dopamine (DA) binds to five receptors (DAR), classified by their ability to increase (D1R-like) or decrease (D2R-like) cAMP. In humans, most DA circulates as dopamine sulfate (DA-S), which can be de-conjugated to bioactive DA by arylsulfatase A (ARSA). The objective was to examine expression of DAR and ARSA in human adipose tissue and determine(More)
INTRODUCTION Several studies reported that the pregnancy-specific hormone placental lactogen (hPL) is expressed at both mRNA and protein levels in breast cancer. The overall objective was to establish hPL, the product of the CSH1 and CSH2 genes, as a biomarker for breast cancer. METHODS CSH expression was determined at the mRNA level in breast cancer cell(More)
We established that human adipose cells and the human adipose cell line LS14 express the calcium-sensing receptor (CaSR) and that its activation induces inflammatory cytokine production. Also, its expression is enhanced upon exposure to obesity-associated proinflammatory cytokines. We have thus proposed that CaSR activation may be associated with adipose(More)
