Summary
Mutations in TRIM37 cause MULIBREY nanism, while its overexpression is linked to cancers. TRIM37
Area of Science:
- Cell Biology
- Genetics
- Oncology
Background:
- Loss-of-function mutations in TRIM37 cause MULIBREY nanism, characterized by growth impairment and tumor predisposition.
- Increased TRIM37 copy number is observed in breast cancers and neuroblastomas.
- TRIM37's role in centrosome biology is crucial for understanding its function in disease.
Purpose of the Study:
- To review the emerging roles of TRIM37 in centrosome biology.
- To discuss the therapeutic potential of targeting TRIM37 in cancer.
Main Methods:
- Literature review of TRIM37 research.
- Analysis of TRIM37's molecular mechanisms in centrosome regulation.
- Discussion of therapeutic strategies targeting TRIM37.
Main Results:
- TRIM37 deletion leads to aberrant centrosomal assemblies and defective chromosome segregation.
- TRIM37 overexpression targets CEP192, inhibiting centrosome maturation and increasing mitotic errors.
- Elevated TRIM37 sensitizes cells to the PLK4 inhibitor centrinone.
Conclusions:
- TRIM37 plays a critical role in centrosome biology, influencing cell division and genome stability.
- Understanding TRIM37's function offers potential for novel cancer therapies.
- Targeting TRIM37 or its pathways may provide new avenues for treating TRIM37-associated diseases and cancers.

Centrioles and Centrosomes
4.0K
Most animal cells comprise a pair of centrioles together called a centrosome. The cell duplicates its centrosome and contains two centrosomes side-by-side, which begin to move apart during the prophase. As the centrosomes migrate to two different sides of the cell, microtubules start extending from each centrosome toward the other end. The mitotic spindle is composed of the centrosomes and their emerging microtubules.

Destabilization of Microtubules
2.9K
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...

The Spindle Assembly Checkpoint
3.3K
The spindle assembly checkpoint is a molecular surveillance mechanism ensuring the fidelity of chromosome segregation during anaphase. The checkpoint monitors the completion of all the prerequisite steps before chromosome segregation to determine whether the segregation process should proceed or be delayed.
Many proteins function together to control the spindle assembly checkpoint. Mutations affecting these proteins may allow cells to proceed into anaphase prematurely, resulting in the...

Histone Variants at the Centromere
4.6K
Histone variants are the histone proteins with structural and sequence variations. These variants may be regarded as “mutant” forms that replace their canonical histone counterparts in the nucleosomes. Specific post-translational modifications on the histone variants enable further chromatin complexity and regulate tissue-specific gene expression. The most common histone variants are from histone H2A, H2B, and linker histone H1 families. However, several variants of histone H3...

Spindle Assembly
3.8K
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 Instability
5.4K
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...
