Abstract

Background: Hypercholesteremia is the major cause of cardiovascular diseases. It results from elevated cholesterol levels in the blood. LDL cholesterol is removed from the circulation by using the LDL receptor. Red mold rice or red yeast rice is produced by fermentation of the Monascus Purpureus yeast on rice. Many researchers suggest that the active component in Red Yeast Rice (monacolin k) serves as a treatment for hypercholesteremic patients.

Methods: By using NCBI databases, specifically GenBank to analyze DNA sequence and mRNA sequence of LDLR gene. GenBank file format was helpful to extract an accession number of the gene, number of amino acids, exons, and length of nucleotides. FASTA format was also useful to retrieve the nucleotide sequence and get the function of the protein. BLAST was used to compare the protein product of the LDLR gene between humans and pan paniscus (pygmy chimpanzee).

Results: In accession number NC_000019, the number of amino acids in protein product is 44389 bp, and the number of exons found is 18. On the other hand, the gene is located in chromosome 19. The function of LDLR gene is to control the production of LDL receptor where the low-density lipoprotein particles attach to it and are taken into the cell ending up in the lysosome where the protein is degraded and cholesterol is made which will inhibit 3-hydroxy-3-methylglutaryl coenzyme A (HMG CoA) reductase that controls the production of cholesterol. Finally, many organisms have the same gene like dogs, cows, mice, rats, zebrafish, and frogs.

Conclusion: Mutation in the LDLR gene causing high level of cholesterol in the blood especially LDL (Low-density Lipoprotein). Monacolin k that found in red yeast rice (RYR) is safe and natural alternative treatment for hypercholesteremic patients by lowering the cholesterol level in the blood.
