Project Description
The Rubin lab studies aging using heterochronic parabiosis, a surgical procedure whereby young and old mice are joined together so that they share a common circulatory system. To better understand aging-associated brain deterioration and potentially modifiable or even reversible aspects of it, the Rubin lab has performed single-cell transcriptomic profiling of young and old mouse brains after parabiosis. The data consists of 10x Genomics single-cell RNA-seq measurements for roughly 160k cells obtained from heterochronic pairs in which 3- to 4-month-old mice were joined with 20- to 22-month-old mice. In a collaboration with HMS Research Computing, CCB equipped the Rubin lab with a cloud-based Posit Connect server, and helped deploying a performant R/Shiny application to the server to enable interactive exploration of the data.
