Summary
Chromosomal instability (CIN) drives cancer, often caused by lagging chromosomes. Our research reveals that faster microtubule assembly is a key source of this instability in cancer cells.
Area of Science:
- Oncology
- Cell Biology
- Genetics
Background:
- Chromosomal instability (CIN) is a hallmark of cancer, but its origins remain unclear.
- Lagging chromosomes are known to precede chromosome missegregation in cancer cells.
Purpose of the Study:
- To investigate the mechanisms generating lagging chromosomes.
- To identify novel sources of CIN in cancer.
Main Methods:
- Discussed the generation of lagging chromosomes.
- Presented recent findings on microtubule dynamics and CIN.
Main Results:
- Increased microtubule assembly rates were identified as a source of CIN.
- This provides a new mechanistic link between microtubule dynamics and cancer progression.
Conclusions:
- Faster microtubule assembly contributes to chromosomal instability in cancer.
- Understanding these mechanisms may reveal new therapeutic targets for cancer treatment.

6.4K
Microtubules are hollow cylindrical filaments having a diameter of approximately 25 nm and a length that varies from 200 nm to 25 μm. GTP-bound tubulin subunits form αβ-heterodimers for microtubule assembly. These core building blocks interact longitudinally, polymerizing into protofilaments. The protofilaments then interact with one another through lateral bonding forces to form stable cylindrical microtubules. These cylindrical filaments are dynamic as they undergo repeated...

01:45Destabilization of Microtubules
3.8K
The destabilization of microtubules can occur during different stages of the microtubule lifecycle, such as nucleation or elongation. It can take place at either end of the microtubule or in the microtubule lattices as a whole. The lifespan of individual microtubules within a cell varies according to the cell type and stage of the cell cycle. During interphase, the lifespan of the microtubule is about 30 minutes, while during cell division, it is about 15 minutes. In axonal microtubules of...

Microtubules form through the end-to-end polymerization of tubulin heterodimers. Kinetochore microtubules originate from the spindle poles, and their plus-ends connect with the kinetochores on sister-chromatids. Ndc80 protein complexes, present on the kinetochore, form low-affinity links with the plus end of these kinetochore microtubules.
Plus-end depolymerization releases tubulin heterodimers from the terminal region of the microtubule. As tubulin subunits are lost, the Ndc80 complexes detach...

01:23Microtubule Formation
8.0K
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...

02:11Forces Acting on Chromosomes
4.1K
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.
