Not exact matches

Previous research had shown that Topisomerase II was involved in earlier cellular processes like DNA replication, and the enzyme was still detectable even during later phases of meiosis.

When researchers suppressed the ARF gene in mole - rat cells during the reprogramming process to iPSCs, the cells stopped proliferation with sign of cellular senescence, while the opposite happens with mouse cells.

«TIA - 1 is known for its ability to regulate gene expression during cellular stress,» says Hewett, who studies the processes that suppress the severe electrical storms in the brain, leading to seizures.

Mutations can be caused by copying errors in the genetic material during cell division and by exposure to radiation, chemicals, or viruses, or can occur deliberately under cellular control during the processes such as meiosis or hypermutation.

Recently, researchers led by John Hallenbeck, M.D., an NINDS senior investigator and co-senior author of the study, found that a cellular process called SUMOylation goes into overdrive in a certain species of ground squirrel during hibernation.

Scientists at the Montreal Neurological Institute and Hospital - The Neuro, McGill University, have made important discoveries about a cellular process that occurs during normal brain development and may play an important role in neurodegenerative diseases.

During those years, the way we study fundamental biological processes underwent a major shift that has now culminated in sequenced human genomes, knowledge of many cellular processes, and a clear path to unraveling roles for individual molecules.

The aims of the CEMC are to define the step-wise molecular and cellular alterations that occur during the process of carcinogenesis; determine how environmental exposures cause key genetic mutations and epigenetic changes that underlie carcinogenesis; and discover the impact of environmental factors on the generation and maintenance of cancer stem cells.

seek to identify the mutational processes underlying mutational signatures found in cancers, characterise the mutational processes operating in normal cells, use phylogenetic analyses of somatic mutations in humans to explore cellular lineages during embryonic development

Autophagy is a cellular process that plays an important role during the development and maintenance of tumors, providing them with the metabolic plasticity to meet their energetic needs, and requirements for cellular building blocks.

The biological process of cellular senescence represents an ideal paradigm to examine the role of the DNA damage response, epigenetically determined chromatin structure, and metabolic reprogramming during tissue aging and cancer development.

When you sleep your brain literally processes the knowledge, memories, information, and cellular waste that accumulates in it during the day, as does your body.

The conversion of calories from their stored nutrient state to the form that can be burned by your muscle cells is achieved, during aerobic exercise, through the process of cellular respiration, which requires oxygen, and the delivery of oxygen through your bloodstream to your active muscle cells is directly related to your heart rate.

The pre-eminent curiosity that I retain regarding health practitioners is that specialists in nutrition on occasion appear to not possess the adequate level of biochemical grounding to explain the vital processes happening at the cellular level during fasting and through manipulation of eicosanoids (fatty acids), conversely from my personal experiences, experts in biochemistry don't apply their vast knowledge of these complex physiological systems to basic fundamentals of nutrition in a sensible, practical sense.

Cardiorespiratory fitness is a measure of how well your body is able to transport oxygen to your muscles during prolonged exercise, and also of how well your muscles are able to absorb and use the oxygen, once it has been delivered, to generate adenosine triphosphate (ATP) energy via cellular respiration (cellular respiration is a chemical process in your body's cells that converts the energy stored in the food you eat into the ATP form of energy that is recruited for use by your muscles).
