Summary
Tumor-derived VEGF-D promotes lymphatic metastasis not by forming new vessels, but by dilating existing collecting lymphatics via prostaglandins. This finding challenges the established role of VEGF-D in lymphatic vessel induction.
Area of Science:
- Oncology
- Cancer Biology
- Lymphatic Biology
Background:
- Vascular Endothelial Growth Factor C (VEGF-C) and VEGF-D are traditionally linked to lymphatic metastasis.
- Their established role involves inducing the formation of new lymphatic vessels within and around tumors.
Discussion:
- This study investigates the precise mechanism by which tumor-secreted VEGF-D drives lymphatic metastasis.
- It challenges the conventional view, proposing an alternative pathway for VEGF-D's pro-metastatic function.
Key Insights:
- Tumor-derived VEGF-D promotes metastasis by inducing prostaglandin-dependent dilation of collecting lymphatics.
- This dilation occurs in lymphatics located outside the primary tumor mass.
- The findings suggest a novel mechanism distinct from lymphatic vessel induction.
Outlook:
- Further research can explore targeting prostaglandin pathways to inhibit VEGF-D-mediated metastasis.
- Understanding this mechanism could lead to new therapeutic strategies for preventing cancer spread.
- This work redefines the role of VEGF-D in the complex process of metastasis.

02:30Metastasis
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...

02:38Mitogens 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...
01:24Regulation of Angiogenesis and Blood Supply
Rapidly dividing tumors, embryos, and wounded tissues require more oxygen than usual, lowering the oxygen concentration in the blood. At low oxygen or hypoxic conditions, an oxygen-sensitive transcription factor called the hypoxia-inducible factor 1 or HIF1 is activated. HIF1 is a dimeric protein of alpha (ɑ) and beta (β) subunits. Under optimal oxygen conditions, HIF1β is present in the nucleus while HIF1ɑ remains in the cytosol. HIF1ɑ is hydroxylated by prolyl hydroxylase and factor...
01:10Mechanism of Angiogenesis
Blood vessel formation starts early during embryonic development, around day 7. In the extraembryonic yolk sac, mesodermal precursor cells called hemangioblast proliferate and differentiate into angioblast. Angioblasts express vascular endothelial growth factor receptor 2 or VEGFR2, which binds VEGF-A, a proangiogenic factor, guiding blood vessel formation. VEGF signaling promotes angioblasts to form a blood island in the developing embryo. Angioblasts further differentiate, giving rise to...
01:35Cancer 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...
01:41Non-Canonical Wnt Signaling Pathways
Wnt is a zygotic effect gene that is expressed during very early embryonic development. It regulates various processes in animals starting from early development through the adult stage, such as organogenesis in the embryo and maintenance of neuronal and blood stem cells. Wnt proteins can induce a wide variety of intracellular pathways depending upon the specific abilities of different Wnt ligands to form a complex with shared and cognate receptors in the presence of different co-receptors. The...
