Summary
Researchers controlled the rotation direction of microtubule (MT) assemblies for biomachines. Altering microtubule preparation conditions successfully switched rotational motion, enabling tunable biomachine development.
Area of Science:
- Biomolecular engineering
- Nanotechnology
- Cellular mechanics
Background:
- The microtubule (MT)-kinesin system is a foundation for biomolecular motor-based artificial machines.
- Ring-shaped MT assemblies are promising for biomachine development but lack directional control.
- Tuning the rotational direction (clockwise/counterclockwise) of MT assemblies is crucial for advanced applications.
Purpose of the Study:
- To investigate methods for controlling the direction of rotational motion in ring-shaped MT assemblies.
- To establish a basis for developing tunable, handedness-regulated artificial biomachines.
Main Methods:
- Preparation of ring-shaped microtubule assemblies under varied conditions.
- Observation and analysis of the rotational motion of the MT rings.
- Correlation of MT lattice structural rearrangements with rotational direction.
Main Results:
- Successfully controlled the direction of rotational motion of ring-shaped MT assemblies.
- Demonstrated that altering microtubule preparation conditions influences rotational direction.
- Linked changes in rotational direction to structural rearrangements within the MT lattice.
Conclusions:
- The study provides a method to control the handedness of MT ring rotation.
- This control is essential for developing efficient, tunable artificial biomachines.
- Findings offer significant direction for creating novel biomachines with adjustable asymmetric properties.

02:50Spindle Assembly
Spindle assembly occurs through three, often coexisting, pathways – the centrosome-mediated pathway, the chromatin-mediated pathway, and the microtubule-mediated pathway – collectively contributing to form a robust spindle apparatus.
In most cells, centrosomes are the primary microtubule nucleation centers. In the centrosome-mediated pathway, the G2-prophase transition triggers centrosome maturation and increased microtubule nucleation. Progressive nucleation results in a microtubule array...

02:15The Contractile Ring
Contractile rings are composed of microfilaments and are responsible for separating the daughter cells during cytokinesis. Contractile ring assembly proceeds along with other cell cycle events; however, very few mechanistic details are known about the timing and coordination of the contractile rings with the cell cycle.
A small GTPase, RhoA, controls the function and assembly of the contractile ring. RhoA belongs to the Ras superfamily of proteins. The activation of formins by RhoA promotes...

01:43The Movement of Organelles and Vesicles
In eukaryotic cells, cytoskeletal filaments such as actin, microtubules, and intermediate filaments form a mesh-like cytoskeletal network. These filaments serve as tracks for transporting cellular cargo. Specialized motor proteins use the chemical energy stored in adenosine triphosphate (ATP) for this transport. During interphase, microtubules are polarized, with the plus-end towards the cell periphery and the minus-end towards the cell center. Two microtubule-associated motor proteins,...
01:23Microtubule Formation
Microtubules are dynamic structures that undergo continuous assembly and disassembly. They originate from specialized multi-protein complexes known as microtubule organizing centers or MTOCs. Within the MTOC, the point of origin of the microtubule is known as the minus end, while the end radiating outward is the plus end. Microtubules serve two primary functions — the organization of spindle complexes to separate sister chromatids during mitotic or meiotic cell division and the formation of...
02:11Forces Acting on Chromosomes
During mitosis, chromosome movements occur through the interplay of multiple piconewton level forces. In prometaphase, these forces help in chromosome assembly or congression at the equatorial plane, eventually leading to their alignment at the metaphase plate. The forces acting on the chromosomes are space and time-dependent; therefore, they vary with the position of the chromosomes as the cell progresses through mitosis.
