Back in July, BioEssays had a slew of interesting papers on cellular evolution, and July had another, that I thought worth mentioning:
Finding treasures in frozen cells: new centriole intermediates – recent findings from cryo-electron tomography give insights into centriole biogenesis.
Evolution of size and pattern in the social amoebas – The fruiting bodies of slime molds comprise the earliest communal cell-cell interactions, and this essay examines the diversity in fruiting body structures.
Evolution of the Cytoskeleton – Remarkable conservation of sequence within prokaryotes and eukaryotes, but not between them, represents a conundrum for cellular evolution. The solution appears to be the drastically changing protein functions, with nucleotide triphosphate binding as the retained protein structure between these two domains of life.
Simultaneous origin of homochirality, the genetic code and its directionality – Additional conundrums surround the origins of Earth’s biochemistry, and are addressed here in a new hypothesis.
The evolving concept of tumor microenvironments – Cellular evolution today.
