(Medical Xpress)—Mitochondria are symbiotic organelles that reside in most of the body's cells and power cellular functions. They contain their own DNA, called mtDNA, and they produce adenosine triphosphate (ATP), which ...
(Medical Xpress)—Two of the most enticing ideas in cells biology have recently converged to create a paradigm shift of epic proportions. The first is that not only is it possible for mitochondria to emigrate from their ...
(Medical Xpress)—Perhaps the boldest attempt to date at a single unified explanation of cancer is that offered by Albert Szent-Gyorgi in his classic book, The Living State. That was over 40 years ago. His insights on the ...
