A new January 2021 study by the Ecole Polytechnique Federale de Lausane in the field of chronobiology sees Western medicine finding the first steps on its way towards a concept known for many hundreds of years in the field of Chinese Medicine as to time and the organs of the body. And in Unani Tibb medicine regarding time and position of the liver.
The study found that, “many of the liver's genes seem to be both zonated and rhythmic, meaning that they are regulated by both their location in the liver and the time of the day. These dually regulated genes are mostly linked to key functions of the liver, e.g. the metabolism of lipids, carbohydrates, and amino acids,”
"The work reveals a richness of space-time gene expression dynamics of the liver, and shows how compartmentalization of liver function in both space and time is hallmark of metabolic activity in the mammalian liver,"
