Evolution: functional evolution of nuclear structure. [PDF]

, 2011
The evolution of the nucleus, the defining feature of eukaryotic cells, was long shrouded in speculation and mystery. There is now strong evidence that nuclear pore complexes (NPCs) and nuclear membranes coevolved with the endomembrane system, and that ...

A Deeply Branching Lineage in Heterolobosea (Discoba) With Multiflagellated and Multigrooved Life Stages

Journal of Eukaryotic Microbiology, Volume 72, Issue 5, September/October 2025.
ABSTRACT Several distantly related, deep‐branching lineages within the eukaryotic tree of life share what is known as the “typical excavate” morphology. This cell architecture includes a suspension‐feeding ventral groove, supported by complex and specific structures of the cytoskeleton, and a vane‐bearing posterior flagellum.

Flavonoids as Promising Akt1 Inhibitors in Cancer Medicine: Insights From Molecular Docking, Dynamics, DFT Calculations, and In Vitro Validation

Cancer Reports, Volume 8, Issue 8, August 2025.
ABSTRACT Background The PI3K/Akt/mTOR signaling pathway is commonly deregulated in different types of cancers, contributing to tumor proliferation, persistence, and resistance to treatment. Akt1, a crucial kinase within this pathway, plays a critical role in tumor progression and the occurrence of therapeutic resistance.

A study of various environmental factors on the growth, encystment and survival of free living amoebae : a thesis presented in partial fulfilment of the requirements for the degree of Master of Science in Microbiology at Massey University [PDF]

, 1985
Free-living amoebae (FLA) are soil organisms which have a worldwide distribution. Interest was raised when they were implicated in two fatal and several non-fatal infections in humans. This investigation involved examination of the role and/or effect of
