The genomes of animal progenitors evolved as mosaics of old, new, rearranged, and repurposed protein domains, genes and pathways and paved the way for the origin and evolution of animals.
A critical analysis of recent single-cell transcriptomic studies of Drosophila blood cells confirms the extreme plasticity of the major phagocyte class, identifies a new class of blood cell, and suggests relationships to blood cells in other insects.
Airborne PM2.5 exposure triggers oxidative stress and mitochondrial apoptosis in placental trophoblast cells via the KLF9/CYP1A1 transcriptional axis, ultimately leading to adverse pregnancy outcomes.

The foundations of genomic complexity in multicellular animals have deep roots in their unicellular prehistory, both in terms of innovations in gene content, as well as the evolutionary dynamics of genome architecture.
Genetic variations that underlie common autoimmune disease genes are predominantly regulatory and modify the expression of multiple genes within the HLA gene complex and throughout the immune system.
