The Tumor Microenvironment02:17

The Tumor Microenvironment

7.4K
Every normal cell or tissue is embedded in a complex local environment called stroma, consisting of different cell types, a basal membrane, and blood vessels. As normal cells mutate and develop into cancer cells, their local environment also changes to allow cancer progression. The tumor microenvironment (TME) consists of a complex cellular matrix of stromal cells and the developing tumor. The cross-talk between cancer cells and surrounding stromal cells is critical to disrupt normal tissue...

Cancer Cell Migration through Invadopodia

3.0K
Invadosome is a broad category of cell surface structures with proteolytic activity that  degrades the extracellular matrix (ECM). Invadosomes are present in normal cell types, including macrophages, endothelial cells, and neurons, as well as tumor cells. Although the macrophage podosomes and tumor cell invadopodia are classified as invadosomes, they have different structures, molecular pathways, and functions. Podosomes are short structures that last for a few minutes. However,...

Cancer Stem Cells and Tumor Maintenance02:40

Cancer Stem Cells and Tumor Maintenance

5.7K
Early diagnosis and treatment can often cure cancer. However, even with treatment, residual cells called cancer stem cells (CSC) might remain, often causing tumor recurrence. These cancer stem cells possess the potential for self-renewal and multi-lineage differentiation and are often responsible for the therapeutic resistance displayed in most cancers.
Cancer stem cells are thought to originate from tissue-specific normal stem cells or progenitor cells. The normal stem cells usually reside in...

Adaptive Mechanisms in Cancer Cells02:53

Adaptive Mechanisms in Cancer Cells

6.7K
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,...

Tumor Progression02:07

Tumor Progression

7.0K
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...

Cancers Originate from Somatic Mutations in a Single Cell02:21

Cancers Originate from Somatic Mutations in a Single Cell

14.2K
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...

Area of Science:

  • Oncology
  • Cancer Biology
  • Cell Biology

Background:

  • Tumor dissemination into the stroma initiates the metastatic cascade.
  • Stromal fibroblasts actively influence cancer invasion, but a systems framework is lacking.
  • Understanding stromal biology's role in metastasis requires analyzing invasion sub-phenotypes.

Purpose of the Study:

  • To develop a systems framework for understanding stromal fibroblast interactions in cancer invasion.
  • To identify and quantify distinct sub-characteristics of collective cancer invasion.
  • To investigate how stromal gene perturbations modulate these invasion characteristics.

Main Methods:

  • Identification of key sub-characteristics of collective cancer invasion.
  • Development of quantitative methods to measure these invasion metrics.
  • Experimental perturbation of stromal fibroblast genes to assess effects on invasion.

Main Results:

  • Distinct sub-characteristics of collective invasion were identified and quantified.
  • Perturbation of stromal genes was shown to modulate specific aspects of cancer invasion.
  • Stromal fibroblast genetic state significantly influences complex cancer dissemination phenomena.

Conclusions:

  • Collective cancer invasion into stroma is a complex process regulated by stromal fibroblasts.
  • Stromal biology plays a crucial role in modulating cancer metastasis.
  • Targeting stromal fibroblast genes may offer new therapeutic strategies for cancer dissemination.
