Metastasis02:30

Metastasis

7.0K
Metastasis is the spread of cancer cells from the original site to distant locations in the body. Cancer cells can spread via blood vessels (hematogenous) as well as lymph vessels in the body.
Epithelial-to-Mesenchymal Transition
The epithelial-to-mesenchymal transition or EMT is a developmental process commonly observed in wound healing, embryogenesis, and cancer metastasis. EMT is induced by transforming growth factor-beta (TGF-β) or receptor tyrosine kinase (RTK) ligands, which further...

Tumor Progression

8.0K
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...

Cancer Stem Cells and Tumor Maintenance02:40

Cancer Stem Cells and Tumor Maintenance

6.4K
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...

Treatment Resistant Cancers02:56

Treatment Resistant Cancers

3.9K
Cancer is the second leading cause of death in the United States. A cancer cell is genetically unstable and hence can mutate faster. They can also modify their microenvironment and escape immune surveillance. The difficulties in treating cancer are further compounded by the emergence of rapid resistance to anticancer drugs. The most common ways to attain resistance in cancer cells include alteration in drug transport and metabolism, modification of drug target, elevated DNA damage response, or...

Cancers Originate from Somatic Mutations in a Single Cell02:21

Cancers Originate from Somatic Mutations in a Single Cell

15.6K
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
  • Metastasis Research

Background:

  • Primary tumor growth and metastasis are complex processes.
  • The specific cancer cell populations responsible for both primary tumor formation and distant metastasis are not fully understood.
  • Identifying these cells is critical for developing effective cancer therapies.

Purpose of the Study:

  • To characterize breast cancer cells with the ability to form primary tumors and re-initiate growth at secondary sites.
  • To identify the functional and molecular factors that enable primary tumor formation and metastatic colonization.

Main Methods:

  • Utilizing advanced single-cell analysis techniques.
  • Employing in vivo models of breast cancer metastasis.
  • Functional assays to assess tumor-initiating and re-initiating capabilities.

Main Results:

  • Identified specific breast cancer cell populations possessing dual tumor-initiating and metastatic potential.
  • Characterized key functional pathways and molecular signatures associated with these cells.
  • Demonstrated the necessity of these determinants for both primary tumor growth and secondary site colonization.

Conclusions:

  • Breast cancer metastasis involves specific cell populations with dual capabilities.
  • Functional and molecular determinants identified are essential for primary tumor formation and metastatic re-initiation.
  • These findings offer potential therapeutic targets for preventing and treating breast cancer metastasis.
