Selected news about mitochondria

From  2014-2016 I collected a series of articles on molecular biology. Since I have gathered enough source material please find some of the most interesting ones I have found. As this subject might be too specific for the layman, the selected articles are among the most suited for a general audience.

Why fathers don’t pass on mitochondria to offspring / June 23, 2016

  • Investigating why paternal mitochondria does not pass-on to their offspring it was revealed that the degeneration occurs when the sperm cell enters the female egg
  • There is a process of self-degeneration of the mitochondria within the masculine cell
  • The mitochondria is then destroyed by autophagosomes cells

Change the Textbooks: This eukaryote completely lacks mitochondria / May 12, 2016

  • Scientists have found an eukaryote without mitochondria
  • The mechanism used instead was cytosolic sulfur mobilization system (SUF)
  • Organisms from the genus Monocercomonoides were discovered using this mechanism

Why do we still have mitochondrial DNA? / February 18, 2016

  • mitoDNA is too important to encode the nucleus
  • the DNA in the mitochondria are important into building the organelle internal structure
  • A lot of how our organelles work together remains a mystery

Mitochondria on guard of human life / November 17, 2015

  • A new method of non-destructive analysis in living mitochondria has been elaborated
  • The protein transport of electrons (especially cyto c) in the inner mitochondrial membrane leads to the synthesis of ATP
  • They managed to discover a novel approach to surface-enhanced Raman spectroscopy (SERS) thanks to more efficient nanostructures

Cells’ powerhouses were once energy parasites: Study upends current theories of how mitochondria began / October 16, 2014

  • A Study provided an alternative theory to two current theories on the origin of the mitochondria as the circumstances surrounding it remains an enigma
  • By DNA sequencing of the mitochondria and it’s close relatives it is predicted that a bacterial parasite stole energy in the form of ATP from its host
  • Many human genes are derived from mitochondria
