Abstract

The Crigler-Najjar syndrome is extremely rare genetic disease, that is manifested by severe jaundicedue to lack of UDP glucuronosyltransferase 1-A1 (UDP) activity. The main treatment is to use the blue lightphototherapy, during the prolong time, during the day every day. Here, we analyzed human UDP’s correlation with the blue light phototherapy using the nonlinear physico-mathematical model: Resonant Recognition Model (RRM), which proposes that protein activation is electromagnetic in nature within the frequency range of infrared and visible light. We found that human UDP’s are characterized by specific RRM frequency that is related to the blue light radiation. This could be the explicit explanation, why phototherapy with the blue light could replace lack of UDP activity. However, the blue light treatment is less effective with ageing, due to decrease of the blue lightpenetration through skin. Thus, there is a need for alternative treatments. Here, we propose to design de-novopeptide, using this specific RRM frequency. Such peptide, according to RRM, is proposed to have the samebiological function as UDP glucuronosyltransferase 1-A1 and thus can be used for alternative treatment of Crigler-Najjar syndrome.

Highlights

  • The Crigler-Najjar syndrome is extremely rare genetic disease, that is manifested by severe jaundicedue to lack of UDP glucuronosyltransferase 1-A1 (UDP) activity

  • We found that specific Resonant Recognition Model (RRM) frequency for UDP glucuronosyltransferase 1-A1biological function is within the blue light frequency range

  • To make sure that this frequency is related to UDP function in bilirubin metabolism, we have compared these six human UDP’s with beta-barrel protein, that binds bilirubin with high affinity

Summary

Introduction

The Crigler-Najjar syndrome is extremely rare genetic disease, that is manifested by severe jaundicedue to lack of UDP glucuronosyltransferase 1-A1 (UDP) activity. The main treatment is to use the blue lightphototherapy, during the prolong time, during the day every day. The Crigler-Najjar syndrome is extremely rare genetic disease affecting the metabolisms of bilirubin, resulting in a form of non-hemolytic jaundice [1]. This disease is caused by lack of expression of UDP glucuronosyltransferase 1-A1. The only available treatment is phototherapy, which involves radiation of patients with the blue light for an extensive time every day, usually whole night. Similar treatment is used for jaundice in new born babies. There is a need for alternative treatments for Crigler-Najjar syndrome
