J Cell Biol: How Does a Genetic Mutation Induce a Neurological Disease Such as Parkinson’s?

Mutations in multiple genes are directly related to Parkinson’s disease, but researchers are not sure how these mutations affect individuals with Parkinson’s disease. A recent study published in The Journal of Cell Biology, in the study, scientists from Yale University focused on a genetic mutation that induced familial Parkinson’s disease. They found that the gene encodes a specific protein that controls lipids transfer between organelle membranes.     In the…

Principle and Protocol of Chromatin Immunoprecipitation (ChIP)

Introduction: 1. Applications of ChIP: (1) Histone modifying enzyme antibody as “biomarkers”; (2) Analysis of transcriptional regulation; (3) Drug development research; (4) Analysis of DNA damage and apoptosis. 2. Details: The eukaryotic genomic DNA exists in the form of chromatin. Therefore, the study of interactions between protein and DNA in chromatin environment is the basic way to clarify the mechanism of gene expression in eukaryotes. Chromatin immunoprecipitation (ChIP) is currently…
