General description

Human prealbumin is a product of chromosome 18. It is a serum protein, synthesized primarily in the liver. It is a tetrameric protein with a molecular weight of 55 kDa. Human prealbumin is composed of four identical non-covalently bound monomers of 127 amino acid residues arranged with tetrahedral symmetry.

Application

Human prealbumin was used to study reduced transthyretin expression in sera of lung cancer.
Prealbumin from human plasma has been used as a positive control in immunoprecipitation as a reference standard in quantitative rocket immunoelectrophoresis for quantification of cerebrospinal fluid.

Biochem/physiol Actions

Human prealbumin has been observed in carcinoid tumors.
Prealbumin levels are indictors of malnutrition and may be modulated during inflammation. It is regarded as potential marker of protein energy malnutrition (PEM) during chronic kidney failure supported dialysis. Low levels of prealbumin poses high risk to heart failure (HF).

Through the development of gene diagnostic techniques, late-onset transthyretin Met30-associated familial amyloid polyneuropathy (FAP TTR Met30) has been shown to be more prevalent than is generally believed. To examine the electrophysiological features of late-onset FAP TTR Met30 unrelated to endemic

Spleen cells from BALB/c mice which either bore syngeneic sarcomas or were normal controls were cultured in vitro. The culture supernatants of spleen cells from tumor-bearing mice inhibited (blocked) specific cell-mediated cytotoxicity to the tumor borne by the spleen donor.

A nationwide study of CMT and FAP has been performed. In FAP TTR Met30 families with late onset, neuropathy showed male preponderance, low penetrance, little relationship to endemic foci, sensorimotor symptoms beginning distally in the lower extremities with disturbance of
