Electron Transport Chain: Complex I and II

Electron Transport Chain: Complex I and II

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.
ROS generation is regulated and maintained at moderate levels necessary...

Mitochondrial Membranes

Mitochondrial Membranes

A single mitochondrion is a bean-shaped organelle enclosed by a double-membrane system. The outer membrane of mitochondria is smooth and contains many porins - the integral membrane transporters. Porins enable free diffusion of ions and small uncharged molecules through the outer mitochondrial membrane but limit the transport of molecules larger than 5000 Daltons. Further, the outer mitochondrial membrane forms a unique structure called membrane contact sites with other subcellular organelles,...

Mitochondria

Mitochondria

Mitochondria are eukaryotic cellular organelles that are known to produce energy through a process called oxidative phosphorylation. Besides their primary function, mitochondria are involved in various cellular processes, including cell growth, differentiation, signaling, metabolism, and senescence. Age-related changes cause a decline in mitochondrial quality and integrity due to increased mitochondrial mutations and oxidative damage. Thus, aging can severely impact mitochondrial functions,...

The Nucleolus

The Nucleolus

The nucleolus is the most prominent substructure of the nucleus. When it was first discovered, it was considered to be an isolated organelle that forms fibrils and granules. In 1931, the relationship between the nucleolus and chromosomes was first described by Heitz. He observed that the appearance and size of nucleolus varies depending on the stage of the cell cycle. He also noticed constricted regions on different chromosomes clustered together at definite cell cycle stages. These regions,...

Area of Science:

Molecular Biology
Cell Biology
Biochemistry

Background:

NME6 is a nucleoside diphosphate kinase enzyme family member.
NME6 localizes to mitochondria and impacts oxidative phosphorylation.
NME6 interacts with RCC1L, a GTPase involved in mitochondrial translation.

Purpose of the Study:

To investigate the role of NME6 in fundamental cellular processes.
To assess the effects of NME6 overexpression and silencing in MDA-MB-231T breast cancer cells.

Main Methods:

Flow cytometry
Western blotting
Wound-healing assay

Main Results:

NME6 overexpression reduced MDA-MB-231T cell migration.
NME6 altered epithelial-mesenchymal transition (EMT) marker expression.
NME6 influenced cell cycle distribution following DNA damage and impacted the MAPK/ERK pathway.
NME6 did not affect apoptosis.

Conclusions:

NME6 plays a role in regulating cell migration and EMT.
NME6's influence on cell cycle is DNA damage-dependent.
NME6 impacts the MAPK/ERK signaling pathway.
Further research is warranted to elucidate NME6's specific functions.
