Summary
Glycolysis, a key metabolic pathway, impacts tissue development. This study reveals how energy from glucose breakdown regulates signaling to shape developing wings in flies.
Area of Science:
- Developmental Biology
- Metabolic pathways
- Cellular signaling
Background:
- Glycolysis breaks down glucose into pyruvate through enzymatic steps.
- The impact of metabolic catabolism on developmental patterning remains largely unclear.
- Understanding energy metabolism's role in tissue formation is crucial.
Discussion:
- Spannl et al. (2020) establish a link between energy metabolism and tissue formation in Drosophila imaginal discs.
- They demonstrate that ATP generated by glycolysis is essential for developmental processes.
- This research highlights the intricate connection between cellular energy and developmental regulation.
Key Insights:
- Glycolysis-derived ATP fuels the active transport of a smoothened inhibitor.
- This transport mechanism keeps Hedgehog (Hh) signaling in check.
- Proper regulation of Hh signaling is vital for maintaining the correct shape and proportion of developing wings.
Outlook:
- Further research can explore similar metabolic regulation in other developmental contexts.
- Investigating the precise molecular mechanisms of ATP-dependent transport is warranted.
- This study opens new avenues for understanding metabolic diseases affecting development.

9.3K
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...

15.9K
When a ligand binds to a cell-surface receptor, the receptor's intracellular domain changes shape, which may either activate its enzyme function or allow its binding to other molecules. The initial signal is amplified by most signal transduction pathways. This means that a single ligand molecule can activate multiple molecules of a downstream target. Proteins that relay a signal are most commonly phosphorylated at one or more sites, activating or inactivating the protein. Kinases catalyze...

4.3K
Water-soluble hormones cannot cross the plasma membrane, so they rely on protein receptors that span the membrane to trigger intracellular signaling pathways. These pathways then activate second messengers inside the cell, including cAMP or calcium ions.
Many hormones bind to transmembrane G protein-coupled receptors that connect to regulatory G proteins. These G proteins can then activate enzymes such as adenylyl cyclase or phospholipase C. Adenylyl cyclase converts ATP to cAMP, activating...

01:27ATP Driven Pumps I: An Overview
9.4K
ATP-driven pumps, also known as transport ATPases, are integral membrane proteins. They have binding sites for ATP located on the membrane's cytosolic side and the ion-conducting domain in the transmembrane region. These pumps use the free energy released from ATP hydrolysis to move the solutes across cell membranes against an electrochemical gradient.
There are four main types of ATP-driven pumps - P-type, V-type, F-type, and ABC transporter. All these pumps are of varying complexities and...

16.2K
In animals, the mitochondrial F1F0 ATP synthase is the key protein that synthesizes ATP molecules through a complex catalytic mechanism. While the nuclear genome encodes the majority of ATP synthase subunits, the mitochondrial genome encodes some of the enzyme's most critical components. The formation of this multi-subunit enzyme is a complex multi-step process regulated at the level of transcription, translation, and assembly. Defects in one or more of these steps can result in decreased...

7.8K
Many receptor binding ligands are hydrophilic; they do not cross the cell membrane but bind to cell-surface receptors. Thus, their message must be relayed by second messengers present in the cell cytoplasm. There are several second messenger pathways, each with its own way of relaying information. For example, the G protein-coupled receptors can activate both phosphoinositol and cyclic AMP (cAMP) second messenger pathways. The phosphoinositol pathway is active when the receptor induces...
