Tumor Progression02:07

Tumor Progression

6.3K
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...

Gene Evolution - Fast or Slow?

7.1K
The genomes of eukaryotes are punctuated by long stretches of sequence which do not code for proteins or RNAs. Although some of these regions do contain crucial regulatory sequences, the vast majority of this DNA serves no known function. Typically, these regions of the genome are the ones in which the fastest change, in evolutionary terms, is observed, because there is typically little to no selection pressure acting on these regions to preserve their sequences.
In contrast, regions which code...

Cancer-Critical Genes I: Proto-oncogenes

8.9K
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...

Cancers Originate from Somatic Mutations in a Single Cell02:21

Cancers Originate from Somatic Mutations in a Single Cell

11.9K
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...

Summary
This summary is machine-generated.

Prostate cancer evolves along two distinct paths: Canonical and Alternative. The Alternative type arises from genetic changes affecting androgen receptor DNA binding, offering a new framework for understanding disease progression.

Area of Science:

  • Oncology
  • Genomics
  • Evolutionary Biology

Background:

  • Cancer development is an evolutionary process driven by accumulating genetic alterations.
  • These alterations disrupt normal cellular functions, leading to tumor proliferation, invasion, and metastasis.

Purpose of the Study:

  • To investigate the genomic evolution of prostate cancer.
  • To classify prostate tumors based on distinct evolutionary trajectories.

Main Methods:

  • Applied three distinct classification methods to analyze tumor evolution.
  • Integrated results from these methods to identify distinct cancer types.

Main Results:

  • Identified two distinct types of prostate cancer: Canonical and Alternative evolutionary disease types.
  • Proposed the evotype model, where Alternative tumors diverge from Canonical through genetic alterations impacting androgen receptor DNA binding.

Conclusions:

  • The evotype model unifies previous molecular observations in prostate cancer.
  • This new framework provides a powerful tool for investigating prostate cancer progression.
