Summary
Vascular Endothelial Growth Factor A (VEGF) influences numerous cell behaviors like proliferation and migration. Research aims to link in vitro signaling pathways to in vivo tissue development and homeostasis.
Area of Science:
- Molecular Biology
- Cell Biology
- Developmental Biology
Background:
- Vascular Endothelial Growth Factor A (VEGF) is a secreted glycoprotein impacting diverse cellular functions.
- VEGF signaling involves complex cell surface receptors and multiple downstream pathways.
- Understanding VEGF's role in vivo remains a significant research challenge.
Purpose of the Study:
- To investigate the specific signaling pathways of VEGF.
- To determine how in vitro identified pathways regulate in vivo tissue development and homeostasis.
- To elucidate the role of VEGF in maintaining tissue homeostasis.
Main Methods:
- Utilized in vitro cell culture models to study VEGF effects.
- Analyzed the composition of VEGF cell surface receptors.
- Investigated downstream signaling molecule activation.
Main Results:
- VEGF promotes cell proliferation, migration, differentiation, and survival in vitro.
- Identified diverse downstream signaling molecules activated by VEGF receptors.
- Established the broad cellular effects of VEGF in tissue culture.
Conclusions:
- VEGF is a versatile signaling molecule with profound effects on cellular behavior.
- Further research is needed to connect in vitro VEGF signaling mechanisms to in vivo physiological processes.
- Clarifying in vivo roles of specific VEGF pathways is crucial for understanding tissue development and homeostasis.

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...
01:16TGF - β Signaling Pathway
The TGF-β signaling pathway regulates cell growth, differentiation, adhesion, motility, and development. TGF-β ligands that induce TGF-β signaling are synthesized in their latent form. Several proteases or cell surface receptors such as integrins act upon the latent form, releasing the active ligand. There are three types of mammalian TGF-βs: (TGF-β1, TGF-β2, and TGF-β3) that bind as homodimers or heterodimers to TGF-β receptors. The TGF-β receptors are of three kinds RI, RII, and RIII. The RI...
01:51Determination
During embryogenesis, cells become progressively committed to different fates through a two-step process: specification followed by determination. Specification is demonstrated by removing a segment of an early embryo, “neutrally” culturing the tissue in vitro—for example, in a petri dish with simple medium—and then observing the derivatives. If the cultured region gives rise to cell types that it would normally generate in the embryo, this means that it is specified. In contrast, determination...
02:33Hedgehog Signaling Pathway
The Hedgehog gene (Hh) was first discovered due to its control of the growth of disorganized, hair-like bristles phenotype in Drosophila, much like hedgehog spines. Hh plays a crucial role in the development of organs and the maintenance of homeostasis in both invertebrates and vertebrates. However, while Drosophila has only one Hh protein, mammals have multiple functional Hedgehog proteins - Sonic (Shh), Desert (Dhh), and Indian Hedgehog (Ihh). All of these homologous proteins have adapted to...

03:14Notch Signaling Pathway
The Notch signaling pathway is a major intracellular signaling pathway that is highly conserved over a broad spectrum of metazoan species. It stands unique from other intracellular signaling mechanisms in animals because notch protein itself acts as the receptor as well as the primary signaling molecule.
The Notch gene came into the limelight in 1914 after the discovery that its mutation in Drosophila melanogaster leads to a serrated (or "notched") wing margin phenotype. It was not until 1985...
