Insights

Galectins, proteins involved in cancer progression, are key targets for therapy. Understanding their role in tumor blood vessels offers new therapeutic strategies.

Area of Science:

  • Oncology
  • Molecular Biology
  • Immunology

Background:

  • Galectins are carbohydrate-binding proteins with diverse roles in cancer.
  • They influence tumor cell transformation, angiogenesis, immune evasion, and metastasis.
  • Galectins expressed by tumor endothelial cells are crucial for cancer progression.

Purpose of the Study:

  • To investigate the role of galectins in tumor progression, particularly those expressed by endothelial cells.
  • To highlight galectins as potential therapeutic targets in cancer treatment.

Main Methods:

  • This study reviews the known functions of galectins in cancer progression.
  • It focuses on the specific contributions of endothelial galectins within the tumor vasculature.

Main Results:

  • Galectins promote key steps in cancer progression, including angiogenesis and metastasis.
  • Endothelial galectins play a significant role in supporting tumor growth and spread.
  • Targeting galectins in the tumor vasculature presents a promising therapeutic avenue.

Conclusions:

  • Galectins are multifunctional targets for cancer therapy.
  • Understanding the role of galectins in tumor endothelium is vital for developing effective galectin-targeting therapies.

Selectins01:25

Selectins

Cell adhesion is  an essential aspect of multicellularity. While stable cell interactions usually occur between cells of the same type, transient cell interactions occur between cells of different tissue types, such as between neutrophils and endothelial cells. Selectins are one class of cell adhesion molecules (CAMs) that bind carbohydrate ligands to form transient cell adhesion. They are rod-like proteins with a long extracellular part of variable length ending with the lectin domain, which...
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 specific...
Regulation of Angiogenesis and Blood Supply01:24

Regulation 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...
Activation of Integrins01:15

Activation of Integrins

Integrins bind ligands and transmit information from outside the cell to inside or vice-versa through an "outside-in signaling" or "inside-out signaling."
In "outside-in signaling," external factors in the extracellular space bind to exposed ligand binding sites on integrins. This causes the inactive protein to undergo a conformational change to become active. Integrins are often clustered on the cell membrane. Repetitive and regularly spaced ligand binding events provide an effective stimulus.
Receptor Downregulation in MVBs01:15

Receptor Downregulation in MVBs

Multivesicular bodies (MVBs) are mature endosomes that sort ubiquitinated proteins and then fuse with lysosomes to degrade the sorted proteins. Epidermal growth factor (EGF) and its receptor (EGFR) form a complex that can be internalized through endocytosis, sorted into an MVB, and later degraded.
The EGFR can initiate signaling pathways that  lead to cell proliferation, migration, and differentiation. Overexpression of EGFR  stimulates cells to proliferate. Excessive  EGFR activation may...

Transducer Mechanism: Enzyme-Linked Receptors

Enzyme-linked receptors are cell-surface receptors acting as an enzyme or associating with an enzyme intracellularly. They make excellent drug targets. Drugs can bind to the extracellular ligand-binding domain or directly affect their enzymatic domain and alter their activity.
Major types that are helpful drug targets include:
