Regulation of Angiogenesis and Blood Supply

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...

Mechanism of Angiogenesis

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...

PI3K/mTOR/AKT Signaling Pathway

PI3K/mTOR/AKT Signaling Pathway

The mammalian target of rapamycin (mTOR) is a serine/threonine kinase that regulates growth, proliferation, and cell survival in response to hormones, growth factors, or nutrient availability. This kinase exists in two structurally and functionally distinct forms: mTOR complex 1 (mTORC1) and mTOR complex 2 (mTORC2). The first form (mTORC1) is composed of a rapamycin-sensitive Raptor and proline-rich Akt substrate, PRAS40. In contrast, mTORC2 consists of a rapamycin-insensitive companion...

cAMP-dependent Protein Kinase Pathways

cAMP-dependent Protein Kinase Pathways

Cyclic Adenosine Monophosphate (cAMP) is an essential second messenger that activates protein kinase A (PKA) and regulates various biological processes. A single epinephrine molecule binds to GPCR and activates several heterotrimeric G proteins, each stimulating multiple adenylyl cyclase, amplifying the signal, and synthesizing large numbers of cAMP molecules. Small changes in cAMP concentration affect PKA activity. The binding of four cAMP molecules induces a conformational change in PKA,...

Pharmacogenomics: Identification of New Drug Targets

Pharmacogenomics: Identification of New Drug Targets

Advances in genomics have profoundly influenced drug discovery by increasing both the speed and accuracy of pharmaceutical development. Pharmacogenomics, which examines how genetic variation influences drug response, facilitates the identification of novel therapeutic targets and enables patient stratification for personalized treatment. These strategies contribute to improved drug efficacy, minimized adverse effects, and more efficient clinical trial design.Mapping genetic differences...

Clot Retraction and Fibrinolysis

Clot Retraction and Fibrinolysis

After a fibrin clot is formed, the next step is clot retraction, a vital process facilitated by platelet contractile proteins, such as actin and myosin. These proteins pull the fibrin strands closer together and condense the clot. This action reduces the size of the clot, creating a smaller, denser structure that effectively seals off the damaged vessel. Clot retraction consolidates the clot and helps with wound healing by bringing the edges of the damaged blood vessel closer together.

Summary

Flufenamic acid (FFA) promotes angiogenesis, the formation of new blood vessels, in laboratory and animal studies. This effect is linked to increased expression of key angiogenesis genes and activation of AMPK signaling pathways.

Background:

Angiogenesis is crucial for development, tumor growth, and metastasis.
Flufenamic acid (FFA) is an anti-inflammatory drug affecting cell membrane ion fluxes.
The specific role of FFA in angiogenesis remains largely unexplored.

Purpose of the Study:

To investigate the effect of Flufenamic acid (FFA) on angiogenesis.
To determine the molecular mechanisms underlying FFA's potential role in blood vessel formation.

Main Methods:

In vitro studies using human umbilical vein endothelial cells (HUVECs) to assess tube formation and proliferation.
RT-PCR analysis to quantify mRNA levels of angiogenesis-related genes (VEGF, e-NOS, AAMP).
In vivo chick embryo chorioallantoic membrane (CAM) assay to evaluate macroscopic blood vessel formation.
Western blotting to assess the activation of AMP-activated protein kinase (AMPK).

Main Results:

FFA treatment (12 h) significantly promoted HUVEC tube formation without impacting cell proliferation.
FFA significantly increased the mRNA accumulation of VEGF, e-NOS, and AAMP.
The chick embryo chorioallantoic membrane assay demonstrated that FFA enhances macroscopic blood vessel formation.
Western blotting revealed significantly higher levels of phosphorylated AMPK in FFA-treated cells.

Conclusions:

Flufenamic acid (FFA) demonstrates pro-angiogenic properties both in vitro and in vivo.
FFA likely promotes angiogenesis by enhancing endothelial cell tube formation.
AMPK activation is suggested as a key mechanism mediating FFA's pro-angiogenic effects.
