What This Study Did, in Plain Language

What Was Tested

Researchers studied Copper (Supplement) in this randomized controlled trial publication.

The aim of this study was to assess by means of an in vitro challenge the mRNA relative abundance of ccs, sod1, coxIV, mtIIa and atox in peripheral mononuclear cells (PMNCs) obtained from healthy individuals, acutely and chronically supplemented with small-to-moderate amounts of copper.

Why It Was Studied

Assessment of proteins in blood and other tissues has failed to identify markers of early copper effects on health.

Studies in animal models show that chaperone of SOD (CCS) respond to changes of copper status.

Who Took Part

By PubMed's age tags, the people studied were adults and middle-aged adults, both men and women.

How the Study Was Run

The researchers set it up as a randomized and placebo-controlled study.

The participants were allocated by chance, so the Copper (Supplement) group and the comparison group should start out alike.

A placebo (an inactive look-alike) gave the Copper (Supplement) group a baseline to be compared against.

Biochemical indicators were assessed at basal (T0) and after 2 (T2) and 60 days (T60).

What Was Measured

Assessment of proteins in blood and other tissues has failed to identify markers of early copper effects on health.

At these times PMNCs were obtained, challenged with 1, 5 or 20 μM Cu-histidine for 20 h and the mRNA relative abundance of the selected genes assessed by real time PCR.

The subject headings attached to it are Cation Transport Proteins, Copper, Copper Transport Proteins, Dietary Supplements, Electron Transport Complex IV, Leukocytes, Mononuclear and Metallochaperones.

What This Means in Plain Language

The paper is a randomized and placebo-controlled study of Copper (Supplement).

The publication is from 2012 (Biometals : an international journal on the role of metal ions in biology, biochemistry, and medicine), a journal based in Netherlands.

Our Notes on the Compound

Copper (Supplement): The active site of cytochrome c oxidase is described as containing copper ions that are essential for electron transfer.
