Summary
Electrophilic eicosanoids modify proteins, offering therapeutic potential for inflammation and oxidative stress. However, they may also cause neurotoxicity by inducing protein aggregation, necessitating further research into their selective action.
Area of Science:
- Biochemistry
- Molecular Biology
- Pharmacology
Background:
- Electrophilic eicosanoids are reactive lipid mediators derived from arachidonic acid.
- These compounds exert diverse biological effects, including anti-inflammatory and anti-proliferative actions.
- Their ability to covalently modify proteins is central to their function.
Purpose of the Study:
- To explore the dual role of electrophilic eicosanoids in biological systems.
- To investigate their therapeutic potential and mechanisms of action.
- To understand the factors influencing their protein modification selectivity.
Main Methods:
- Biochemical assays to identify protein targets.
- Proteomic studies to map modification sites.
- Analysis of cellular responses to electrophilic eicosanoids.
Main Results:
- Electrophilic eicosanoids modulate the NF-κB pathway and redox-sensitive proteins.
- Evidence suggests their involvement in neurotoxicity and neurodegeneration via protein aggregation.
- Numerous protein targets have been identified, indicating pleiotropic effects.
Conclusions:
- Protein modification by electrophilic eicosanoids is influenced by protein/compound structure and cellular context.
- Understanding selectivity is crucial for harnessing therapeutic benefits and mitigating risks.
- Further research is needed to elucidate their precise pathophysiological roles.

01:11IP3/DAG Signaling Pathway
Membrane lipids such as phosphatidylinositol (PI) are precursors for several membrane-bound and soluble second messengers. Specific kinases phosphorylate PI and produce phosphorylated inositol phospholipids. One such inositol phospholipids are the phosphatidylinositol-4,5 bisphosphate [PI(4,5)P2], present in the inner half of the lipid bilayer. Upon ligand binding, GPCR stimulates Gq proteins to turn on phospholipase Cꞵ. Activated phospholipase Cꞵ cleaves PI(4,5)P2 and produces two-second...
01:31Lipid-derived Compounds in the Human Body
Fats and lipids are crucial components in the human body. Some lipid-derived compounds, such as fat-soluble vitamins, eicosanoids, lipoproteins, and glycolipids, also play unique roles to support various biological processes .
Fat-soluble Vitamins
Fat-soluble vitamins, including vitamins A, D, E, and K, are required in minimal quantities, but their deficiencies can lead to severely abnormal physiological conditions. For example, vitamin A deficiency can cause night blindness, dry skin, delayed...

01:26Signal Transduction: Overview
Cells respond to many types of information, often through receptor proteins positioned on the membrane. They respond to chemical signals, such as hormones, neurotransmitters, and other signaling molecules, initiating a series of molecular reactions to produce an appropriate response. This is called signal transduction. Cells also coordinate different responses elicited by the same signaling molecule via mediators, allowing molecular cross-talk.
Typically, signal transduction involves three...

01:15Amplifying Signals via Second Messengers
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...
01:22Role of Ephrin-Eph Signalling in Intestinal Stem Cell Renewal
Erythropoietin-producing hepatocellular carcinoma receptor (Eph) and its ligand, Eph receptor-interacting protein (Ephrin) were first discovered in the human carcinoma cell line, hence the name. Ephrin-Eph interaction guides cells to reach their appropriate location in adult tissues. They also play an essential role in the immune system by helping in immune cell migration, adhesion, and activation. Based on their structure and function, Eph is divided into two classes — EphA and EphB.
01:24Intracellular Signaling Cascades
Once a ligand binds to a receptor, the signal is transmitted through the membrane and into the cytoplasm. The continuation of a signal in this manner is called signal transduction. Signal transduction only occurs with cell-surface receptors, which cannot interact with most components of the cell, such as DNA. Only internal receptors can interact directly with DNA in the nucleus to initiate protein synthesis. When a ligand binds to its receptor, conformational changes occur that affect the...
