Repeated global adaptation across plant species.

Global adaptation occurs when all populations of a species undergo selection toward a common optimum. This can occur by a hard selective sweep with the emergence of a new globally advantageous allele that spreads throughout a species' natural range until reaching fixation. This evolutionary process leaves a temporary trace in the region affected, which is detectable using population genomic methods.

Alteration of the Tumor Microenvironment With Intratumoral Dendritic Cells Before Chemotherapy in ERBB2 Breast Cancer: A Nonrandomized Clinical Trial.

Importance: Current chemotherapy regimens for patients with ERBB2 (formerly HER2)-positive breast cancer are associated with considerable morbidity. These patients may benefit from more effective and less toxic therapies.

Objective: To evaluate the safety, immunogenicity, and preliminary efficacy of intratumoral (IT) delivery of conventional type 1 dendritic cells (cDC1) in combination with ERBB2-targeted therapies.

Mutation potentiates migration swamping in polygenic local adaptation.

Locally adapted traits can exhibit a wide range of genetic architectures, from pronounced divergence at a few loci to small frequency divergence at many loci. The type of architecture that evolves depends strongly on the migration rate, as weakly selected loci experience swamping and do not make lasting contributions to divergence. Simulations from previous studies showed that even when mutations are strongly selected and should resist migration swamping, the architecture of adaptation can collapse and become transient at high mutation rates.
