LEARNING HORMONE ACTION MECHANISMS WITH BIOINFORMATICS

Mechanisms of hormone action.

Circulating hormones play an important role in regulating the flux through metabolic pathways. In general, hormones regulate either the activity of key enzymes of metabolism or the activity of protein transport systems such as those found in the plasma membrane and in the inner mitochondrial membrane. Little is known about the mechanism of action of hormones on transport systems, so the discuss...

Mechanisms of Hormone Action

3.1. How Hormones Change Their Target Cells Hormones are chemical messengers that invoke profound changes within target cells. There are two fundamental mechanisms by which such changes occur: • Activation of enzymes and other dynamic molecules: Most enzymes shuttle between conformational states that are catalytically active versus inactive, on versus off. Many hormones affect their target cell...

Mechanisms of thyroid hormone action.

Our understanding of thyroid hormone action has been substantially altered by recent clinical observations of thyroid signaling defects in syndromes of hormone resistance and in a broad range of conditions, including profound mental retardation, obesity, metabolic disorders, and a number of cancers. The mechanism of thyroid hormone action has been informed by these clinical observations as well...

The potential regulatory mechanisms of the gonadotropin-releasing hormone in gonadotropin transcriptions identified with bioinformatics analyses

BACKGROUND The regulation of gonadotropin synthesis and release by gonadotropin-releasing hormone (GnRH) plays an essential role in the neuroendocrine control of reproduction. However, the mechanisms underlying gonadotropin regulation by GnRH pulse frequency and amplitude are still ambiguous. This study aimed to explore the molecular mechanisms and biological pathways associated with gonadotrop...
