Cancer Cell Migration through Invadopodia01:35

Cancer Cell Migration through Invadopodia

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, invadopodia can...
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.
The mTOR pathway or the...

Adaptive Mechanisms in Cancer Cells02:53

Adaptive 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.
Some of the advantages that cancer cells have on normal cells include - enhanced ability to divide without terminally differentiating, induce new blood vessel formation,...

Metastasis02:30

Metastasis

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...

Area of Science:

  • Biochemistry
  • Molecular Biology
  • Oncology

Background:

  • Matrix remodeling proteases are crucial in cancer development.
  • Proteases influence extracellular matrix metabolism and growth factor bioavailability.
  • They also regulate chemokines, cytokines, and cell adhesion molecules.

Purpose of the Study:

  • To explore the complex roles of proteases in cancer.
  • To understand how proteases function in cascades and proteolytic pathways.
  • To identify therapeutic targets within these pathways.

Main Methods:

  • Examining mechanistic studies of protease function.
  • Analyzing individual protease gene functions in mouse cancer models.
  • Focusing on intersecting proteolytic activities in neoplastic development.

Main Results:

  • Proteases provide a protumor advantage by modulating various factors.
  • Some proteases indirectly activate zymogens, contributing to cancer progression.
  • Proteolytic pathways, not individual proteases, are critical.

Conclusions:

  • Protease cascades are integral to cancer development.
  • Understanding these pathways can reveal therapeutic targets.
  • Targeting proteolytic pathways may offer novel anti-cancer strategies.
