What is the Origin of Hepatic Biomarkers?

The term combines the Greek root "hepar," meaning liver, with "biomarker," a term that emerged in the 1980s to denote a measurable characteristic that indicates a biological process. The clinical utility of these markers, such as Alanine Aminotransferase (ALT) and Aspartate Aminotransferase (AST), has been foundational in diagnostics for decades. The field of Hepatocrinology further formalizes the study of the intricate, bidirectional relationship between hepatic function and the endocrine system.

What is the Mechanism of Hepatic Biomarkers?

Hepatic biomarkers operate through various mechanisms. Liver enzyme markers like ALT and AST are released into the circulation when hepatocytes are damaged or dying, providing a signal of cellular injury. Other markers, such as albumin and SHBG, are synthesized by the liver, and their concentrations reflect the liver's protein synthetic capacity, which directly impacts the bioavailability and clearance kinetics of circulating steroid hormones. Alterations in these markers signal a need for clinical attention and potential therapeutic adjustment.

Hepatic Biomarkers

Meaning

Hepatic Biomarkers are measurable indicators in the blood or other tissues that reflect the functional status, injury, or pathological processes occurring within the liver. In endocrinology and metabolic health, these markers are crucial for assessing the liver’s capacity to metabolize hormones, synthesize transport proteins like Sex Hormone-Binding Globulin (SHBG), and regulate glucose and lipid metabolism. Monitoring these biomarkers is a non-invasive way to evaluate liver health, particularly during hormone replacement therapy or metabolic interventions.
