#Medsky🧪 #oncosky Experimental findings from cell lines, 🐁 models, and clinical samples strongly support the role of #tetraploidy in cancer evolution but many studies have reported very large & presumably highly #polyploid cells in drug-resistant & metastatic tumors
Top: Prevalence of Microsporidia in DToL insect genomes. Microsporidian genomes recovered from insect hosts, split by taxonomic order. F: female, M: male, U: unspecified sex. Bottom: Simplified proposed generalized lifecycle for Microsporidia. This proposed model posits that each nucleus is a diploid, and that microsporidian reproduction mirrors reproduction in Fungi with stages similar to karyogamy, plasmogamy, and a stable “heterokaryon” (known as a diplokaryon in Microsporidia). Importantly, both the diplokaryotic and monokaryotic phases are parasitic, and species may spend most of their lifecycle in one or the other phase, giving rise to “diploid” and “tetraploid” lineages.
