To compare the RNAs present in dendrites and somas of individual neurons, we manually separated the dendrites and soma of primary mouse hippocampal neurons using a micropipette and performed RNA-sequencing on each subcellular fraction such that we obtained the subcellular transcriptomes of the same cell. Overall design: 16 individual neurons were collected and dissected (yielding a total of 32 soma and dendrite samples) from multiple cultures across multiple days. ERCC spike-in control RNA was added to each sample.

View SamplesWe show that the transfer of the adult ventricular myocyte (AVM) transcriptome into either a fibroblast or an astrocyte converts the host cell into a cardiomyocyte. Transcriptome-effected cardiomyocytes (tCardiomyocytes) display morphologies, immunocytochemical properties, and expression profiles of postnatal cardiomyocytes. Cell morphology analysis shows that tCardiomyoctes are elongated and have a similar length-to-width ratio as AVMs. These global phenotypic changes occur in a time-dependent manner and confer electroexcitability to the tCardiomyocytes. tCardiomyocyte generation does not require continuous overexpression of specific transcription factors; for example, the expression level of transcription factor Mef2c is higher in tCardiomyocytes than in fibroblasts, but similar in tCardiomyocytes and AVMs. These data highlight the dominant role of the gene expression profile in developing and maintaining cellular phenotype. The transcriptomeinduced phenotype remodelinggenerated tCardiomyocyte has significant implications for understanding and modulating cardiac disease development.
Transcriptome transfer provides a model for understanding the phenotype of cardiomyocytes.

View SamplesUsing microdissected dendrites from primary cultures of hippocampal neurons of two mouse strains (C57BL/6 and Balb/c) and one rat strain (Sprague-Dawley), we investigate via microarrays, subcellular localization of mRNAs in dendrites of neurons to assay the evolutionary differences in subcellular dendritic transcripts localization.

View SamplesMouse adult female brains cortex (C57BL/6, Charles River Laboratories, Inc.) was isolated and stored immediately at -80C. Subsequently, the mRNA (15g) was isolated using TRIzol Reagent and MicroFastTrack 2.0 Kit (Invitrogen). A Sample of 5g was assessed on Affymetrix Mouse 430.2 array. Aliquots from the leftovers of the same cortical mRNA were diluted to single-cell RNA levels (0.1, 1, and 10 pg) and independently aRNA amplified for a total of 2 and 4 rounds and assessed on Affymetrix Mouse 430.2 arrays.
