Insights

Angiogenesis inhibitors show promise in preclinical cancer studies but yield mixed clinical results, particularly for ovarian cancers. Combining these inhibitors with other drugs may offer a more effective therapeutic strategy.

Area of Science:

  • Oncology
  • Vascular Biology

Background:

  • Neoplastic cells exhibit the ability to induce blood vessel growth (angiogenesis).
  • Inhibiting peri-neoplastic blood vessel growth has shown potential in restricting primary tumor and metastasis growth in preclinical models.

Purpose of the Study:

  • To highlight discrepancies between preclinical and clinical findings regarding angiogenesis inhibitors.
  • To focus on the specific context of ovarian cancers and their treatment.

Main Methods:

  • Review of preclinical and clinical studies on angiogenesis inhibitors.
  • Analysis of therapeutic outcomes in ovarian cancer models.

Main Results:

  • Clinical efficacy of angiogenesis inhibitors has not met preclinical expectations.
  • Discrepancies exist between animal study results and human clinical trials.

Conclusions:

  • Angiogenesis inhibitors may be less effective than anticipated based on preclinical data.
  • Combination therapy involving angiogenesis inhibitors and other drugs shows potential for treating ovarian cancers.

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...

Cancer Therapies

Cancer therapies are various modes of treatment, such as surgery, radiation therapy, and chemotherapy that are administered to cancer patients.
However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...

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...
Mechanism of Angiogenesis01:10

Mechanism 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...
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...
