Moreover, it has shed light on the pathways through which most anticancer therapeutics induce tumor cell death, including targeted therapy and immunotherapy. These mechanistic studies have paved the way for the development of therapeutics directly targeting either pro- or antiapoptotic proteins. Notably, the US Food and Drug Administration (FDA) approved the BCL-2 inhibitor venetoclax in 2016, with additional agents currently undergoing clinical trials.

Recent work has shed light on the importance of RNA damage, which triggers a host of conserved RNA quality control mechanisms. Because many RNA species are transient, and because of their ability to be retranscribed, RNA damage has largely been ignored. Yet, because of the connection between damaged RNA and DNA during transcription, and the association between essential complexes that process or decode RNAs, notably spliceosomes and ribosomes, the appropriate handling of damaged RNAs is critical for maintaining cellular homeostasis.

Here, we review recent advances using single-cell transcriptomics to uncover novel mechanisms that govern neurogenesis and angiogenesis in the germinal matrix of the prenatal human brain.
