Insights

Membrane-type 1 matrix metalloproteinase (MT1-MMP) is crucial for tumor invasion, but also vital for normal physiology. Understanding MT1-MMP

Area of Science:

  • Biochemistry and Molecular Biology
  • Cancer Research
  • Cell Biology

Background:

  • Membrane-type 1 matrix metalloproteinase (MT1-MMP) is a key enzyme in pericellular proteolysis, cell migration, and invasion.
  • MT1-MMP plays a critical role in collagenolysis, which is essential for tumor invasion and metastasis.
  • MT1-MMP has diverse physiological functions, making its inhibition a complex challenge.

Purpose of the Study:

  • To review the multifaceted activities of MT1-MMP.
  • To explore the relationship between MT1-MMP activities and cancer initiation and progression.
  • To discuss methods for real-time monitoring of MT1-MMP activities and cell surface behaviors.

Main Methods:

  • Literature review of MT1-MMP functions, substrates, and binding partners.
  • Analysis of MT1-MMP's role in cancer biology.
  • Examination of current and potential real-time monitoring techniques for MT1-MMP.

Main Results:

mTOR Signaling and Cancer Progression03:03

mTOR 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.

Targeted Cancer Therapies02:57

Targeted Cancer Therapies

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...

Mitogens and the Cell Cycle02:38

Mitogens and the Cell Cycle

Mitogens and their receptors play a crucial role in controlling the progression of the cell cycle. However, the loss of mitogenic control over cell division leads to tumor formation. Therefore, mitogens and mitogen receptors play an important role in cancer research. For instance, the epidermal growth factor (EGF) - a type of mitogen and its transmembrane receptor (EGFR), decides the fate of the cell's proliferation. When EGF binds to EGFR, a member of the ErbB family of tyrosine kinase...

Inhibition of Cdk Activity02:34

Inhibition of Cdk Activity

The orderly progression of the cell cycle depends on the activation of Cdk protein by binding to its cyclin partner. However, the cell cycle must be restricted when undergoing abnormal changes. Most cancers correlate to the deregulated cell cycle, and since Cdks are a central component of the cell cycle, Cdk inhibitors are extensively studied to develop anticancer agents. For instance, cyclin D associates with several Cdks, such as Cdk 4/6, to form an active complex. The cyclin D-Cdk4/6 complex...

The Tumor Microenvironment02:17

The Tumor Microenvironment

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...
