Light can be utilized to control gene function

Light can be used as an accurate method to control gene expression, shows groundbreaking optogenetics study. In a new study, the researchers were able to induce and inhibit the expression of genes in mammalian cell cultures and were able to regulate intracellular protein levels using light signals. The approach was also used to regulate gene transcription at endogenous genomic sites when combined with CRISPR/Cas9 technology.
