Insights

Src-family kinases (SFKs) drive cancer progression by promoting cell motility, invasion, and metastasis. Targeting SFKs, like c-Src, offers a promising strategy for cancer therapy and vascular normalization.

Area of Science:

  • Oncology
  • Molecular Biology
  • Cancer Research

Background:

  • Src-family kinases (SFKs) are intracellular non-receptor tyrosine kinases implicated in oncogenesis.
  • SFKs promote tumor cell motility, proliferation, invasion, and metastasis.
  • Novel roles in epithelial-to-mesenchymal transition (EMT) and tumor microenvironment modulation are emerging.

Purpose of the Study:

  • To review the novel roles of SFKs, particularly c-Src, in cancer progression.
  • To discuss the impact of SFKs on EMT, tumor microenvironment, and metastasis.
  • To explore the therapeutic potential of Src inhibitors in cancer treatment and vascular normalization.

Main Methods:

  • Literature review of studies on SFKs in cancer.
  • Analysis of SFK involvement in EMT, angiogenesis, and metastasis.
  • Discussion of clinical relevance of Src inhibitors.

Main Results:

  • SFKs, especially c-Src, play critical roles in mediating EMT.
  • SFKs modulate the tumor endothelial barrier, facilitating cancer cell invasion and metastasis.
  • Src inhibition shows potential for vascular normalization and as a cancer therapy.

Conclusions:

  • SFKs are key regulators of cancer cell invasion and metastasis through EMT and microenvironment interactions.
  • Targeting SFKs, including c-Src, presents a viable therapeutic strategy for various cancers.
  • Src inhibitors may offer dual benefits in normalizing tumor vasculature and inhibiting cancer progression.

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...

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,...

Overview of Cell-Matrix Interactions01:24

Overview of Cell-Matrix Interactions

The extracellular matrix or ECM holds cells together to form a tissue and allows the cells within the tissue to communicate. ECM comprises proteins such as fibronectin, collagen, laminin, etc. The most abundant protein in this space is collagen. Collagen fibers are interwoven with carbohydrate-containing protein molecules called proteoglycans. ECM allows cell migration and provides a structural scaffold at cell adhesion that anchors the cell when the extracellular matrix proteins interact with...

Cell Migration01:19

Cell Migration

Cell migration is a process by which the cells move from one location to another, playing an essential role in embryological development, repair and regeneration, immune response, and metastasis. Cells migrate in response to chemical or mechanical signals generated by specific organs or tissues. The overall mechanism includes three steps - polarization, protrusion, and release. Polarization involves the formation of a distinct cell front and rear, which determines the direction of movement.

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...

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...
