Mitochondria, often called the cell’s energy powerhouse, are small organelles which reside in a cell’s cytoplasm and convert food into energy or building blocks. Mutations in mitochondrial DNA, or mtDNA, … Continue Reading Performing single-cell surgery with a laser-powered nanoblade.
Since their discovery in the 1950s, transfer RNAs (tRNAs) have been best known for their role in helping the cell make proteins from messenger RNA templates. However, recent studies have … Continue Reading Researchers discover new species of tRNA responsible for sex-biased cancer proliferation.
For years, scientists have been puzzled by the presence of short stretches of genetic material floating inside a variety of cells, ranging from bacteria to mammals, including humans. These fragments … Continue Reading Researchers identify new role for tRNA fragments in tumour suppression.
Cholera is caused when the bacterium Vibrio cholerae infects the small intestine. The disease is characterized by acute watery diarrhea resulting in severe dehydration. EPFL scientists have now demonstrated that … Continue Reading Scientists identify Cholera’s mode of horizontal gene transfer and drug-resistance.
Mouse cells and tissues created through nuclear transfer can be rejected by the body because of a previously unknown immune response to the cell’s mitochondria, according to an international study … Continue Reading Previously unseen immune reaction identified for stem cell transplants.
