Microtubule Instability02:17

Microtubule Instability

5.2K
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...

Cancers Originate from Somatic Mutations in a Single Cell

12.5K
Cancer arises from mutations in the critical genes that allow healthy cells to escape cell cycle regulation and acquire the ability to proliferate indefinitely. Though originating from a single mutation event in one of the originator cells, cancer progresses when the mutant cell lines continue to gain more and more mutations, and finally, become malignant. For example, chronic myelogenous leukemia (CML) develops initially as a non-lethal increase in white blood cells, which progressively...

Abnormal Proliferation02:23

Abnormal Proliferation

4.6K
Under normal conditions, most adult cells remain in a non-proliferative state unless stimulated by internal or external factors to replace lost cells. Abnormal cell proliferation is a condition in which the cell's growth exceeds and is uncoordinated with normal cells. In such situations, cell division persists in the same excessive manner even after cessation of the stimuli, leading to persistent tumors. The tumor arises from the damaged cells that replicate to pass the damage to the...

The Retinoblastoma Gene01:20

The Retinoblastoma Gene

4.2K
Tumor suppressor genes are normal genes that can slow down cell division, repair DNA mistakes, or program the cells for apoptosis in case of irreparable damage. Hence, they play an essential role in preventing the proliferation of damaged cells.
The first-ever tumor suppressor gene called Rb was identified in retinoblastoma - a rare eye tumor in children. In inherited forms of the disease, a child inherits one defective copy of the Rb gene, which predisposes them to retinoblastoma. However,...

Area of Science:

  • Oncology
  • Genetics
  • Cancer Biology

Background:

  • Chromosomal instability (CIN) is a hallmark of cancer, contributing to tumorigenesis and progression.
  • CIN is increasingly recognized in adult-type diffusely infiltrating gliomas, correlating with genomic alterations and poor prognosis.

Purpose of the Study:

  • To review the mechanisms of CIN.
  • To explore the link between CIN and malignancy.
  • To discuss the prognostic and therapeutic implications of CIN in various cancers, with a focus on gliomas.

Main Methods:

  • Literature review of studies on chromosomal instability.
  • Analysis of CIN's role in tumorigenesis and malignant progression.
  • Examination of CIN's clinical significance and treatment potential in cancers, particularly gliomas.

Main Results:

  • CIN is a fundamental property of cancer, present in diverse malignancies including gliomas.
  • In gliomas, CIN is associated with increased copy number burden, chromothripsis, and adverse clinical outcomes.
  • CIN's role in glioma development may contribute to therapeutic resistance.

Conclusions:

  • CIN is an early factor in glioma development, potentially explaining treatment resistance.
  • Targeting CIN presents a promising avenue for future glioma therapies.
  • Further research is needed to clinically measure and therapeutically exploit CIN in gliomas.
