Adaptive Mechanisms in Cancer Cells02:53

Adaptive Mechanisms in Cancer Cells

5.9K
Cancer cells accumulate genetic changes at an abnormally rapid rate due to the defects in the DNA repair mechanisms. From an evolutionary perspective, such genetic instability is advantageous for cancer development. Mutant cell lines accumulate a series of beneficial mutations that contribute to their progression into cancer.
Some of the advantages that cancer cells have on normal cells include - enhanced ability to divide without terminally differentiating, induce new blood vessel formation,...

Cancers Originate from Somatic Mutations in a Single Cell

12.4K
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...

What is Cancer?

10.9K
Cells and tissues must meticulously coordinate their activities for the normal functioning of the human body. Therefore, they exhibit socially responsible behavior - resting, growing, dividing, differentiating, or dying - for the organism’s benefit. Cancer arises when cells divide uncontrollably and invade other tissues or organs.
Although people have known about cancer for centuries, it was only in 1761 that Giovanni Morgagni of Padua performed a detailed autopsy of...

Cancer02:18

Cancer

49.0K
Cancers arise due to mutations in genes involved in the regulation of cell division, which leads to unrestricted cell proliferation. Modern science and medicine have made great strides in the understanding and treatment of cancer, including eradicating cancer in some patients. However, there is still no cure for cancer. This is largely due to the fact that cancer is a large group of many diseases.

Targeted Cancer Therapies02:57

Targeted Cancer Therapies

7.8K
The targeted cancer therapies, also known as “molecular targeted therapies,” take advantage of the molecular and genetic differences between the cancer cells and the normal cells. It needs a thorough understanding of the cancer cells to develop drugs that can target specific molecular aspects that drive the growth, progression, and spread of cancer cells without affecting the growth and survival of other normal cells in the body.
There are several types of targeted therapies against...

T Cell Activation and Clonal Selection01:22

T Cell Activation and Clonal Selection

1.8K
T cells are integral to our adaptive immune system, recognizing and effectively responding to foreign antigens. T cell activation and clonal selection are pivotal in orchestrating this immune response. This article elucidates these mechanisms, detailing the roles of cluster of differentiation (CD) markers, major histocompatibility complex (MHC) molecules, costimulatory signals, and the process of clonal selection.
Naive T cells that have not yet encountered an antigen express two primary CD...

Area of Science:

  • Developmental Biology
  • Cancer Biology
  • Evolutionary Biology

Background:

  • Clonal selection and drift are fundamental processes influencing both normal tissue homeostasis and cancer progression.
  • The precise biological mechanisms and environmental factors governing these clonal dynamics are not fully understood.

Purpose of the Study:

  • To elucidate the shared mechanisms of clonal selection and drift in normal and cancerous tissues.
  • To explore the roles of distinct stem cell subclasses in tissue development and regeneration.

Main Methods:

  • Comparative analysis of stem cell populations in normal and cancerous tissues.
  • Review of Darwinian evolutionary principles applied to clonal dynamics.
  • Discussion of potential mechanisms driving clonal drift and its interplay with selection.

Main Results:

  • Identified commonalities in clonal selection processes between normal and cancer development.
  • Proposed distinct roles for active (tissue-populating) and dormant (tissue-replenishing) stem cells.
  • Highlighted similarities in clonal drift mechanisms across normal and cancerous conditions.

Conclusions:

  • Stem cell subclasses exhibit conserved functions in clonal selection and tissue dynamics.
  • Understanding clonal drift and selection interplay is crucial for both developmental biology and cancer research.
