Non-coding transcriptome in brain aging

Reprogramming of the non-coding transcriptome during brain development

A recent global analysis of gene expression during the differentiation of neuronal stem cells to neurons and oligodendrocytes indicates a complex pattern of changes in the expression of both protein-coding transcripts and long non-protein-coding RNAs.

Non-Coding RNAs in Cardiac Aging.

Aging has a remarkable impact on the function of the heart, and is independently associated with increased risk for cardiovascular diseases. Cardiac aging is an intrinsic physiological process that results in impaired cardiac function, along with lots of cellular and molecular changes. Non-coding RNAs include small transcripts, such as microRNAs and a wide range of long non-coding RNAs (lncRNAs...

MYC regulates the non-coding transcriptome

Using RNA-seq (RNA sequencing) of ribosome-depleted RNA, we have identified 1,273 lncRNAs (long non-coding RNAs) in P493-6 human B-cells. Of these, 534 are either up- or downregulated in response to MYC overexpression. An increase in MYC occupancy near their TSS (transcription start sites) was observed for MYC-responsive lncRNAs suggesting these are direct MYC targets. MYC binds to the same TSS...

Transcriptome sequencing during mouse brain development identifies long non-coding RNAs functionally involved in neurogenic commitment.

Transcriptome analysis of somatic stem cells and their progeny is fundamental to identify new factors controlling proliferation versus differentiation during tissue formation. Here, we generated a combinatorial, fluorescent reporter mouse line to isolate proliferating neural stem cells, differentiating progenitors and newborn neurons that coexist as intermingled cell populations during brain de...
