Researchers at Kanazawa University report in Proceedings of the National Academy of Sciences how a protein molecular motor can chop off a piece of cell membrane. The constrict-and-cut mechanism resembles that of a ratchet motor, and is of importance in processes mediating the entry of particles into cells.

Using electron microscopy and high-speed atomic force microscopy, researchers show the internal molecular motor behind the gliding mechanism for Mycoplasma mobile to consist of two ATP synthase-like molecules. Sharing a similar structure with ATP synthase suggests a common evolutionary ancestor. This synthase-like ATPase is challenging the origin of cells and proteins themselves.

Publication bias, or the tendency of researchers and journals to not publish uninteresting findings, plagues much of the natural sciences and especially biomedical research. Hiroshima University researchers have developed a meta-analytic technique exploiting publicly available transcriptome databases that avoids the problem—and in so doing, discovered four genes previously unknown to be associated with responding to low-oxygen stress.

Scientists from Japan, Europe and the USA have described a pathway leading to the accelerated flowering of plants in low-nitrogen soils. These findings could eventually lead to increases in agricultural production.
24 May 2021
In collaboration with Kanazawa University, researchers from Osaka City University used high-speed atomic force microscopy (HS-AFM) to visualize at the nanometer level the movement of individual particles within the parasitic bacterium Mycoplasma mobile. After confirming the outline on the surface of the cell structure in an immobilized state with previous data gathered from electron microscopy, the team succeeded in visualizing the real-time movements of the internal structure by scanning the outside of the cell with HS-AFM.

When quiescent neural stem cells in the fruit fly larval brain are activated, they can generate new neurons. In the image, the nucleus of quiescent neural stem cells is labelled by a marker of neural stem cells named Deadpan in magenta, and the cell outline is marked in green.

A brain enzyme activates dormant neural stem cells, revealing how defects in its gene could lead to neurodevelopmental disorders.

Tissue stem cells can self-renew and differentiate, supplying cells necessary for tissues at various developmental stages. However, detailed analysis in vivo is difficult, so the molecular mechanisms underlying the stemness of gastric tissue stem cells have remained a mystery. Here, by using organoids that mimic tissue structure and function in vivo and GeCKO screening to inactivate arbitrary genes, Alk, Bclaf3 and Prkra have been identified as genes regulating stemness.
Actin-dependent nuclear displacement observed in several mitotic mutants in fission yeast.

Cells replicate their genetic material and divide into two identical clones to perpetuate life. Some cells pause in the process with a single, undivided nucleus. When the cell resumes division after such a pause, the nucleus can become caught in the fissure, splitting violently, and killing both cells. But that is not always the case. Researchers from Hiroshima University in Japan are starting to understand how active nuclear displacement rescues cell death.
