Scientist Otto Warburg, whose research activities led to the formulation of the Warburg hypothesis for explaining the root cause of cancer.. The Warburg hypothesis (/ ˈ v ɑːr b ʊər ɡ /), sometimes known as the Warburg theory of cancer, postulates that the driver of carcinogenesis (cancer formation) is insufficient cellular respiration caused by insult (damage) to mitochondria. [1]
Older hypotheses such as the Warburg hypothesis suggest the Warburg effect may simply be a consequence of damage to the mitochondria in cancer. It may also be an adaptation to low-oxygen environments within tumors, or a result of cancer genes shutting down the mitochondria, which are involved in the cell's apoptosis program that kills cancer cells.
Keshav K. Singh is also the founding editor-in-chief of the journal Mitochondrion., [1] founder of the Mitochondria Research and Medicine Society (USA) [2] and the Society for Mitochondrial Research and Medicine (India) [3] He is the author of more than 100 research publications and 3 books related to mitochondrial diseases, aging and cancer.
His book, Life Ascending: The Ten Great Inventions of Evolution, won the 2010 Royal Society Prize for Science Books. [5] He appeared on In Our Time on Radio Four on 13 September 2012, when the topic of discussion was the cell, [6] and again on 15 May 2014, when the topic was photosynthesis.
Mitochondrial DNA has been known to encode 13 proteins. Recently, other short protein coding sequences have been identified, and their products are referred to as mitochondria-derived peptides. [15] The mitochondrial-derived peptide, humanin has been shown to protect against Alzheimer's disease, which is considered an age-associated disease. [16]
Mitochondrial replication is controlled by nuclear genes and is specifically suited to make as many mitochondria as that particular cell needs at the time. Mitochondrial transcription in humans is initiated from three promoters, H1, H2, and L (heavy strand 1, heavy strand 2, and light strand promoters). The H2 promoter transcribes almost the ...
Bruce Nathan Ames (December 16, 1928 – October 5, 2024) was an American biochemist who was a professor of biochemistry and Molecular Biology Emeritus at the University of California, Berkeley, and was a senior scientist at Children's Hospital Oakland Research Institute (CHORI). [2]
Blebbishield emergency program is a process which acts as a last line of defense for cancer stem cells after induction of apoptosis where the apoptotic blebs fuse to shield the cells/nucleus from the destructive force of apoptosis by forming blebbishields. Blebbishields in turn fuse to each other and generate cancer stem cell spheres/cellular ...
