Mitochondria have their own DNA, but the 13 genes in human mitochondria — along with DNA sequences for tRNAs, rRNAs and some small peptides — are massively overshadowed by the 20,000 genes in the human nucleus. Nevertheless, these diminutive mitochondria may have a strong influence on cellular metabolism and susceptibility to metabolic diseases like heart failure or obesity.
Investigators have designed a portable and affordable mobile diagnostic tool, utilizing a cellphone and nanotechnology, with the ability to detect HIV viruses and monitor its management in resource-limited regions.
Researchers have found a potential new pathway to regulate immune response and potentially control inflammatory diseases of the central nervous system such as meningitis and sepsis.
Genetics may predispose some people to both Alzheimer’s disease and high levels of blood lipids such as cholesterol, a common feature of cardiovascular disease, according to a new study.
Study by 72 researchers from eight countries concludes that the Lagoa Santa people are descendants of Clovis culture migrants from North America. Distinctly African features attributed to Luzia were wrong.
Common bacteria that cause foodborne diseases are resistant to antibiotics used to treat infections, according to research that identified 39 genes responsible for this resistance.
Experimenting with lab-grown brain cancer cells, researchers have added to evidence that a shortage of specific tiny molecules that silence certain genes is linked to the development and growth of pediatric brain tumors known as low-grade gliomas.
Scientists have now found a cause for the frequent catastrophic events in the genetic material of cancer cells that have only been known for a few years: If an important DNA repair system of the cells has failed, this promotes fragmentation and defective assembly of the genetic material. Cancer cells with such a repair defect can now possibly be treated by a specific group of drugs.
