Summary
Matrix metalloproteinases (MMPs) promote cancer development by causing genomic instability. Membrane type-1 MMP (MT1-MMP) drives chromosome instability, initiating the transition from normal cells to malignancy.
Area of Science:
- Oncology
- Molecular Biology
- Genetics
Background:
- Elevated matrix metalloproteinases (MMPs) expression is linked to tumor growth and metastasis.
- Emerging evidence implicates MMPs in early cancer development and cell transformation.
- Genomic instability is a hallmark of cancer, but its early drivers are under investigation.
Purpose of the Study:
- To review novel findings on MMPs' role in early cancer development.
- To introduce the concept of proteolysis-driven oncogenesis.
- To emphasize the role of membrane type-1 matrix metalloproteinase (MT1-MMP) in inducing chromosome instability.
Main Methods:
- Literature review of recent studies on MMPs and cancer.
- Conceptual framework development for proteolysis-driven oncogenesis.
- Focus on experimental evidence linking MT1-MMP to chromosomal aberrations.
Main Results:
- MMPs are implicated in promoting genomic instability, contributing to initial cell transformation.
- MT1-MMP is identified as a key factor in inducing chromosome instability.
- This instability facilitates the transition of normal cells towards a malignant state.
Conclusions:
- MMPs, particularly MT1-MMP, play a direct role in the initiation of cancer by driving genomic instability.
- Proteolysis-driven oncogenesis is a novel paradigm for understanding cancer development.
- Targeting MMPs may offer new strategies for preventing or treating early-stage cancers.

01:33Cancer-Critical Genes I: Proto-oncogenes
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.

03:03mTOR Signaling and Cancer Progression
The mammalian target of rapamycin or mTOR protein was discovered in 1994 due to its direct interaction with rapamycin. The protein gets its name from a yeast homolog called TOR. The mTOR protein complex in mammalian cells plays a major role in balancing anabolic processes such as the synthesis of proteins, lipids, and nucleotides and catabolic processes, such as autophagy in response to environmental cues, such as availability of nutrients and growth factors.

02:38The Ras Gene
The Ras-gene-encoded proteins are regulators of signaling pathways controlling cell proliferation, differentiation, or cell survival. The Ras-gene family in humans constitutes three primary members—the HRas, NRas, and KRas. These genes code for four functionally distinct yet closely related proteins—the HRas, NRas, KRas4A, and KRas4B. The involvement of mutant Ras genes in human cancer was first discovered in 1982 and is among the most common causes of human tumorigenesis.

02:53Adaptive Mechanisms in Cancer Cells
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.
