The nuclear-to-cytoplasmic ratio drives cellularization in the close animal relative Sphaeroforma arctica

Omaya Pierre Dudin, Marine Olivetta

The ratio of nuclear content to cytoplasmic volume (N/C ratio) is a key regulator driving the maternal-to -zy-gotic transition in most animal embryos. Altering this ratio often impacts zygotic genome activation and de-regulates the timing and outcome of em ...

Life-cycle-coupled evolution of mitosis in close relatives of animals

Omaya Pierre Dudin, Marine Olivetta

Eukaryotes have evolved towards one of two extremes along a spectrum of strategies for remodelling the nuclear envelope during cell division: disassembling the nuclear envelope in an open mitosis or constructing an intranuclear spindle in a closed mitosis1 ...

A multicellular developmental program in a close animal relative

Chandni Bhickta, Nicolas René Chiaruttini, Omaya Pierre Dudin, Marine Olivetta

All animals develop from a single-celled zygote into a complex multicellular organism through a series of precisely orchestrated processes1,2. Despite the remarkable conservation of early embryogenesis across animals, the evolutionary origins of how and wh ...

DNA methylation enables recurrent endogenization of giant viruses in an animal relative

Omaya Pierre Dudin, Marine Olivetta

5-Methylcytosine (5mC) is a widespread silencing mechanism that controls genomic parasites. In eukaryotes, 5mC has gained complex roles in gene regulation beyond parasite control, yet 5mC has also been lost in many lineages. The causes for 5mC retention an ...
