ch25h, cholesterol 25 hydroxylase

This DNA codes for CH25H, also known as cholesterol 25-hydroxylase, which catalyzes the formation of 25 hydroxycholesterol (25HC) from cholesterol.

Usage and Biology

25 hydroxycholesterol (25 HC) has been reported to have a range of effects on the immune system, including the suppression of production of IgA by B cells and inducing the migration of human peripheral blood monocytes [1]. 25 HC is also found to be able to reverse protein aggregation and restore solubility to the proteins [2]. In our project, we aim to deliver CH25H to the lens, where 25 HC will be produced and reverse aggregated lens protein. Aged-induced cataracts occur when lens proteins get oxidized and clump together. The increase of 25HC in the lens will help to treat cataracts.

Gel Pictures

We designed primers to remove a stop codon and to move CH25H cDNA into iGEM BioBrick. PCR was set up and the gel picture is shown below. The expected size for CH25H PCR check is ~1.1kb. The bands boxed in red are the correct bands.

Sequencing

CH25H was sent to sequencing and the result shows that the CH25H sequencing result is correct (with no stop codon):
