Characterizing the composition of iPSC derived cells from bulk transcriptomics data with CellMap.

Induced pluripotent stem cell (iPSC) derived cell types are increasingly employed as in vitro model systems for drug discovery. For these studies to be meaningful, it is important to understand the reproducibility of the iPSC-derived cultures and their similarity to equivalent endogenous cell types. Single-cell and single-nucleus RNA sequencing (RNA-seq) are useful to gain such understanding, but they are expensive and time consuming, while bulk RNA-seq data can be generated quicker and at lower cost.

Impact of induced pluripotent stem cells on the study of central nervous system disease.

The derivation of pluripotent stem cells from somatic tissues has provided researchers with a source of patient-specific stem cells. The potential applications of this technology are truly momentous, and include cellular modeling of disease processes, drug discovery, and cell-based therapy. Here, we review the use of induced pluripotent stem cells (iPSCs) to study CNS disease.

Overexpression of type-1 adenylyl cyclase in mouse forebrain enhances recognition memory and LTP.

Cyclic AMP is a positive regulator of synaptic plasticity and is required for several forms of hippocampus-dependent memory including recognition memory. The type I adenylyl cyclase, Adcy1 (also known as AC1), is crucial in memory formation because it couples Ca(2+) to cyclic AMP increases in the hippocampus. Because Adcy1 is neurospecific, it is a potential pharmacological target for increasing cAMP specifically in the brain and for improving memory.
