Microbial peptide de-coppers mitochondria: implications for Wilson disease
The Journal of Clinical Investigation
|June 21, 2016
Summary
Methanobactin (MB), a bacterial copper-binding protein, shows therapeutic potential for severe Wilson disease (WD) by reducing copper overload in a rat model. Further clinical trials are warranted for this advanced liver disease treatment.
Area of Science:
- Hepatology
- Biochemistry
- Genetics
Background:
- Wilson disease (WD) involves severe liver damage due to copper overload from ATP7B gene mutations.
- Current treatments include chelation for early stages and liver transplantation for advanced disease.
Purpose of the Study:
- To evaluate the therapeutic efficacy of methanobactin (MB) in a late-stage Wilson disease rat model.
- To explore MB as a potential treatment for severe hepatic pathology in WD.
Main Methods:
- Utilized a Wilson disease rat model mimicking advanced liver pathology.
- Administered methanobactin (MB), a bacterial copper-binding protein, at three distinct late disease stages.
Main Results:
- Methanobactin demonstrated a therapeutic effect in the late-stage WD rat model.
- MB showed potential in mitigating copper overload-induced liver pathology.
Conclusions:
- Methanobactin (MB) presents a rational therapeutic option for severe Wilson disease with advanced liver pathology.
- Clinical trials of MB in human WD patients are recommended.

13.6K
Mitochondrial precursors are translocated to the internal subcompartments via independent mechanisms involving distinct protein machineries called translocases.
Sorting of outer membrane proteins:
Mitochondrial outer membrane proteins are of two types: the transmembrane, beta-barrel porins, and the membrane-anchored, alpha-helical proteins. Beta-barrel porin precursors are translocated by the TOM complex and inserted into the outer mitochondrial membrane by the SAM complex. In contrast,...

Microbiologically Influenced Corrosion (MIC) is a significant form of material degradation caused by the metabolic activities of microorganisms. This phenomenon poses substantial challenges across various industries, including oil and gas, maritime, and water treatment sectors.MIC occurs when microorganisms, such as bacteria, archaea, and fungi, colonize metal surfaces, forming biofilms that alter the local electrochemical environment. These biofilms can lead to the production of corrosive...

01:46Electron Transport Chain: Complex I and II
19.4K
The mitochondrial electron transport chain (ETC) is the main energy generation system in the eukaryotic cells. However, mitochondria also produce cytotoxic reactive oxygen species (ROS) due to the large electron flow during oxidative phosphorylation. While Complex I is one of the primary sources of superoxide radicals, ROS production by Complex II is uncommon and may only be observed in cancer cells with mutated complexes.

01:27Protein Import into the Peroxisomes
5.6K
Cells contain membrane-bound organelles called peroxisomes that oxidize organic molecules by transferring hydrogen atoms to oxygen, producing hydrogen peroxide. Peroxisomes enzymatically convert the released hydrogen peroxide into water and oxygen.
Peroxisomal Protein Import:
Peroxisomes lack the genetic machinery required to code for their own proteins. Hence, most peroxisomal membrane, lumenal and transmembrane proteins are synthesized in the cytoplasm or ER and transported to the peroxisome...

03:03Amyloid Fibrils
12.8K
Amyloid fibrils are aggregates of misfolded proteins. Under most circumstances, misfolded proteins are either refolded by chaperone proteins or degraded by the proteasome. However, in the case of a mutation or a disease, these proteins can accumulate to form large clusters and often further assemble to form elongated fibers, called fibrils.
Amyloid deposits were observed as early as 1639 in the liver and the spleen. In 1854, Rudolph Virchow performed iodine staining,...

01:28The Inner Mitochondrial Membrane
5.0K
The inner mitochondrial membrane is the primary site of ATP synthesis. The inner membrane domain that forms a smooth layer adjacent to the outer membrane is called the inner boundary membrane. This domain contains membrane transporters that drive metabolites in and out of the mitochondria. In contrast, the inner membrane network that invaginates into the matrix space is called the cristae membrane. This domain accounts for principle mitochondrial function as it accommodates the protein...
