Transcriptomes of individual neurons provide rich information about cell types and dynamic states. However, it is difficult to capture rare dynamic processes, such as adult neurogenesis, because isolation from dense adult tissue is challenging, and markers for each phase are limited. Here, Applicants developed Nuc-seq, Div-Seq, and Dronc-Seq. Div-seq combines Nuc-Seq, a scalable single nucleus RNA-Seq method, with EdU-mediated labeling of proliferating cells. Nuc-Seq can sensitively identify closely related cell types within the adult hippocampus. Div-Seq can track transcriptional dynamics of newborn neurons in an adult neurogenic region in the hippocampus. Dronc-Seq uses a microfluidic device to co-encapsulate individual nuclei in reverse emulsion aqueous droplets in an oil medium together with one uniquely barcoded mRNA-capture bead. Finally, Applicants found rare adult newborn GABAergic neurons in the spinal cord, a non-canonical neurogenic region. Taken together, Nuc-Seq, Div-Seq and Dronc-Seq allow for unbiased analysis of any complex tissue.

Provided is a modular construction of synthetic gene circuits in mammalian cells using TALE transcriptional repressors. Provided is a method for achieving regulated expression of two proteins: an expression cassette A comprises a feedback element coding sequence, a promoter A, a protein A and TALER protein A encoding gene linked by means of a self-cleaving polypeptide, and a target sequence A (comprising an shRNA1 target sequence); an expression cassette B comprises a feedback element coding sequence, a promoter B, a protein B and TALER protein B encoding gene linked by means of a self-cleaving polypeptide, and a target sequence B (comprising an shRNA2 target sequence); an expression cassette C comprises a constitutive promoter and an activating element-coding sequence; a recombinant vector A having the expression cassette A, a recombinant vector B having the expression cassette B, and a recombinant vector C having the expression cassette C are introduced into host cells to regulate the expression of protein A and protein B by adding shRNA1 or shRNA2.
