Cancers Originate from Somatic Mutations in a Single Cell02:21

Cancers Originate from Somatic Mutations in a Single Cell

13.2K
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...

Tumor Progression02:07

Tumor Progression

6.6K
Tumor progression is a phenomenon where the pre-formed tumor acquires successive mutations to become clinically more aggressive and malignant. In the 1950s, Foulds first described the stepwise progression of cancer cells through successive stages.
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...

Notch Signaling Pathway03:14

Notch Signaling Pathway

4.6K
The Notch signaling pathway is a major intracellular signaling pathway that is highly conserved over a broad spectrum of metazoan species. It stands unique from other intracellular signaling mechanisms in animals because notch protein itself acts as the receptor as well as the primary signaling molecule.
The Notch gene came into the limelight in 1914 after the discovery that its mutation in Drosophila melanogaster leads to a serrated (or "notched") wing margin phenotype. It was not...

Neurulation01:30

Neurulation

43.2K
Neurulation is the embryological process which forms the precursors of the central nervous system and occurs after gastrulation has established the three primary cell layers of the embryo: ectoderm, mesoderm, and endoderm. In humans, the majority of this system is formed via primary neurulation, in which the central portion of the ectoderm—originally appearing as a flat sheet of cells—folds upwards and inwards, sealing off to form a hollow neural tube. As development proceeds, the...

The Retinoblastoma Gene01:20

The Retinoblastoma Gene

4.3K
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,...

Cancer-Critical Genes I: Proto-oncogenes01:33

Cancer-Critical Genes I: Proto-oncogenes

9.3K
Genes usually encode proteins necessary for the proper functioning of a healthy cell. Mutations can often cause changes to the gene expression pattern, thereby altering the phenotype.
When the function of certain critical genes, especially those involved in cell cycle regulation and cell growth signaling cascades, gets disrupted, it upsets the cell cycle progression. Such cells with unchecked cell cycles start proliferating uncontrollably and eventually develop into tumors.
Such genes that act...

Area of Science:

  • Oncology
  • Pathology
  • Radiology

Background:

  • Tumors exhibiting notochordal differentiation represent a spectrum of neoplastic entities.
  • These tumors range from benign to highly aggressive, posing diagnostic and therapeutic challenges.

Purpose of the Study:

  • To provide a comprehensive overview of the spectrum of tumors demonstrating notochordal differentiation.
  • To delineate the characteristics, clinical behavior, and prognostic implications of these diverse tumors.

Main Methods:

  • Literature review of studies on tumors with notochordal differentiation.
  • Analysis of histopathological features, imaging findings, and clinical outcomes.
  • Classification of tumors based on grade and differentiation.

Main Results:

  • Benign notochordal cell tumors are typically incidental findings requiring no intervention.
  • Conventional chordomas, though low-grade, possess metastatic potential and significant mortality.
  • High-grade tumors, including dedifferentiated chordoma and poorly differentiated chordoma, exhibit aggressive behavior and poor prognosis.

Conclusions:

  • Accurate classification of tumors with notochordal differentiation is crucial for patient management.
  • The spectrum ranges from indolent to highly aggressive neoplasms, necessitating tailored treatment strategies.
  • Further research into the molecular mechanisms driving progression in these tumors is warranted.
