Cytoplasmic Streaming in Plant Cells Emerges Naturally by Microfilament Self-Organization
, 2013 Many cells exhibit large-scale active circulation of their entire fluid contents, a process termed cytoplasmic streaming. This phenomenon is particularly prevalent in plant cells, often presenting strikingly regimented flow patterns.

A permeabilized cell model for studying cell division: a comparison of anaphase chromosome movement and cleavage furrow constriction in lysed PtK1 cells. [PDF]
, 1981 After lysis in a Brij 58-polyethylene glycol medium, PtK1 cells are permeable to small molecules, such as erythrosin B, and to proteins, such as rhodamine-labeled FAB, myosin subfragment-1, and tubulin.

Baculovirus Expression and Functional Analysis of Vpa2 Proteins from Bacillus thuringiensis
Toxins, 2020 The mode of action underlying the insecticidal activity of the Bacillus thuringiensis (Bt) binary pesticidal protein Vpb/Vpa (formerly Vip1/Vip2) is uncertain. In this study, three recombinant baculoviruses were constructed using Bac-to-Bac technology to

Advanced Science, Volume 12, Issue 28, July 24, 2025.In this study, a novel mechanism is unveiled by which ADD1, acting as a molecular switch, coordinates actin branch dynamics and the transport of endocytic viruses and cargoes. Phosphorylation of ADD1 at Ser726 reduces actin branch density, enhancing endosome fusion and attachment to microtubules.
