Electron Transport Chain: Complex I and II01:46

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...
Animal Mitochondrial Genetics02:59

Animal Mitochondrial Genetics

Among all the organelles in an animal cell, only mitochondria have their own independent genomes. Animal mitochondrial DNA is a double-stranded, closed-circular molecule with around 20,000 base pairs. Mitochondrial DNA is unique in that one of its two strands, the heavy, or H, -strand is guanine rich, whereas the complementary strand is cytosine rich and called the light, or L, -strand. Compared to nuclear DNA, mitochondrial DNA has a very low percentage of non-coding regions and is marked by...
Loss of Tumor Suppressor Gene Functions01:12

Loss of Tumor Suppressor Gene Functions

Tumor suppressor genes are normal genes that can slow down cell division, repair DNA mistakes, or program the cells for apoptosis in case of irreparable damage. Hence, they play an essential role in preventing the proliferation of damaged cells.
When the tumor suppressor genes develop mutations or are lost, cells start growing out of control, leading to cancer. However, a single functional copy of the tumor suppressor gene is enough for the cells to maintain their normal functions and cell...
Mitochondria01:37

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,...
Mitochondrial Membranes01:45

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,...

Area of Science:

  • Biochemistry
  • Oncology
  • Genetics

Background:

  • Mitochondrial dysfunction is linked to tumor cell apoptosis resistance and altered metabolism.
  • Hepatocellular carcinoma (HCC) is a heterogeneous cancer with genetic aberrations, including mitochondrial mutations.
  • The p53 family and microRNAs are implicated in mitochondrial dysfunction during hepatocarcinogenesis.

Purpose of the Study:

  • To explore the role of mitochondrial dysfunction-related genes in HCC.
  • To understand the involvement of genes like mfn2 in the p53 network and apoptosis pathways.
  • To identify potential therapeutic targets for HCC based on mitochondrial gene function.

Main Methods:

  • Analysis of gene mutations in mitochondria associated with HCC.
  • Investigation of the p53 family's role in mitochondrial apoptosis.
  • Examination of gene expression patterns in mitochondrial metabolism related to hepatocarcinogenesis.
  • Assessment of microRNA involvement in HCC mitochondrial pathways.

Main Results:

  • Mitochondrial gene mutations contribute to HCC development and progression.
  • The p53 network and specific genes (e.g., mfn2) are crucial in mitochondrial apoptosis.
  • Certain genes exhibit pleiotropic functions in HCC mitochondrial dysfunction.
  • Mitochondrial genes influence HCC response to chemotherapy via apoptosis and autophagy.

Conclusions:

  • Mitochondrial dysfunction is a key factor in HCC pathogenesis.
  • Understanding mitochondrial gene roles offers insights into HCC heterogeneity.
  • Targeting mitochondrial dysfunction-related genes presents a promising avenue for novel HCC therapies.
