Opportunities and tradeoffs in single-cell transcriptomic technologies
Trends Genet. 2023 Nov 10:S0168-9525(23)00231-7. doi: 10.1016/j.tig.2023.10.003. Online ahead of print.ABSTRACTRecent technological and algorithmic advances enable single-cell transcriptomic analysis with remarkable depth and breadth. Nonetheless, a persistent challenge is the compromise between the ability to profile high numbers of cells and the achievement of full-length transcript coverage. Currently, the field is progressing and developing new and creative solutions that improve cellular throughput, gene detection sensitivity and full-length transcript capture. Furthermore, long-read sequencing approaches for single-c...

Strategies for dissecting the complexity of neurodevelopmental disorders
Trends Genet. 2023 Nov 8:S0168-9525(23)00237-8. doi: 10.1016/j.tig.2023.10.009. Online ahead of print.ABSTRACTNeurodevelopmental disorders (NDDs) are associated with a wide range of clinical features, affecting multiple pathways involved in brain development and function. Recent advances in high-throughput sequencing have unveiled numerous genetic variants associated with NDDs, which further contribute to disease complexity and make it challenging to infer disease causation and underlying mechanisms. Herein, we review current strategies for dissecting the complexity of NDDs using model organisms, induced pluripotent stem c...

Retrotransposon renaissance in early embryos
Trends Genet. 2023 Nov 8:S0168-9525(23)00238-X. doi: 10.1016/j.tig.2023.10.010. Online ahead of print.ABSTRACTDespite being the predominant genetic elements in mammalian genomes, retrotransposons were often dismissed as genomic parasites with ambiguous biological significance. However, recent studies reveal their functional involvement in early embryogenesis, encompassing crucial processes such as zygotic genome activation (ZGA) and cell fate decision. This review underscores the paradigm shift in our understanding of retrotransposon roles during early preimplantation development, as well as their rich functional reservoir...

Pioneer factors: roles and their regulation in development
Trends Genet. 2023 Nov 6:S0168-9525(23)00235-4. doi: 10.1016/j.tig.2023.10.007. Online ahead of print.ABSTRACTPioneer factors are a subclass of transcription factors that can bind and initiate opening of silent chromatin regions. Pioneer factors subsequently regulate lineage-specific genes and enhancers and, thus, activate the zygotic genome after fertilization, guide cell fate transitions during development, and promote various forms of human cancers. As such, pioneer factors are useful in directed cell reprogramming. In this review, we define the structural and functional characteristics of pioneer factors, how they bind...

Chromatin bridges: stochastic breakage or regulated resolution?
Trends Genet. 2023 Oct 25:S0168-9525(23)00232-9. doi: 10.1016/j.tig.2023.10.004. Online ahead of print.ABSTRACTGenetic material is organized in the form of chromosomes, which need to be segregated accurately into two daughter cells in each cell cycle. However, chromosome fusion or the presence of unresolved interchromosomal linkages lead to the formation of chromatin bridges, which can induce DNA lesions and genome instability. Persistent chromatin bridges are trapped in the cleavage furrow and are broken at or after abscission, the final step of cytokinesis. In this review, we focus on recent progress in understanding the...
