In Africa, there is a disparity in ethics and permission requirements for molecular research on samples from living people versus ancient DNA. At the precipice of the archaeogenomics revolution, heritage agencies require updated policies and procedures for genetic and genomic research on African ancient DNA.
A study in Cell presents a new approach that increases resolution and throughput compared with existing imaging methods and provides insights into the relationship between transcription and the 3D genome.
Two papers in Cell report large-scale genome-wide association studies that provide new insights into the genetic architecture of haematopoietic phenotypes and emphasize the importance of large, diverse data sets.
Genome instability can lead to a number of human diseases, including neurodegeneration and cancer. In this Review, Zong et al. discuss the various ways in which RNA can both promote genome instability and contribute to genome maintenance.
The development of successful anticancer therapies relies on identifying drug targets that are genuine cancer-specific vulnerabilities. In this article, Lin and Sheltzer discuss how the different genetic and pharmacological methods for identifying and characterizing cancer dependencies each have important strengths and limitations. Responsible and orthogonal use of these methods holds promise for maximizing the ability of preclinical research to translate into clinical benefit.
The growth and survival of cells within tissues can be influenced by competition between different cell clones. Genetic and cell biological studies suggest that cell competition may occur through the molecular recognition of ‘different’ cells, signalling imbalances between cell populations or the mechanical consequences of differential growth rates.
In this Expert Recommendation, the authors review the definitions of classic concepts relating to bacterial gene regulation, with a focus on transcription initiation, and suggest up-to-date, precise definitions to provide a reference for knowledge representation, modelling and future research on bacterial gene regulation.
