New comprehension of physical properties of chromatin may show how genome is encoded and decoded Kumar Jeetendra | December 21, 2020 University of Alberta researchers have found an answer to a basic question in genomic biology that has eluded scientists because the discovery of DNA: Over the nucleus of our cells, is the complex package of DNA and proteins called chromatin a solid or a liquid? Previously, fields like biochemistry operated under the premise that chromatin …
Researchers find out protein that adjusts gene interest to healthy nutrient stages in roundworms Kumar Jeetendra | December 23, 2020 Changing a fertilized egg into a fully functional adult is a complicated endeavor. Cells must split, move, and mature at specific times. Developmental genes control that process, turning on and off at a choreographed way. However, the environment affects development. They discovered a master switch developing worms use to pause growth when nutrients are scarce. …
Study clarifies the impact of getting old on hematopoietic stem cells Kumar Jeetendra | December 25, 2020 By shifting mouse elderly hematopoietic stem cells (aged HSCs) to the environment of young mice (bone marrow niche), it was shown that the pattern of stem cell gene expression was rejuvenated to that of young hematopoietic stem cells. On the other hand, the function of elderly HSCs failed to recover in the young bone marrow …
Study famous how ecDNA fragments pressure gene amplification to generate drug resistance in cancer Kumar Jeetendra | December 26, 2020 Researchers headed by Ludwig San Diego Member Don Cleveland and Peter Campbell of the Sanger Center have solved the puzzle of how free-floating circular DNA fragments, which are almost exclusively found in cancer cells, drive gene amplification to create drug resistance in cancer. The study, published on December 23 in the journal Nature, provides new …
Researchers find out how shattered chromosomes make most cancers cells greater aggressive Kumar Jeetendra | December 27, 2020 Cancer is one of the world’s biggest health afflictions because, unlike some diseases, it’s a moving target, constantly evolving to evade and resist treatment. In a paper published in the December 23, 2020 online dilemma of Nature, researchers at University of California San Diego School of Medicine and the UC San Diego branch of the …
New UCLA-formed gadget moves mitochondria into at least 100,000 or more beneficiary cells Kumar Jeetendra | January 1, 2021 Scientists from the UCLA Jonsson Comprehensive Cancer Center have developed a simple, high-throughput way of transferring isolated mitochondria and their associated mitochondrial DNA into mammalian cells. This approach enables researchers to tailor a key genetic component of cells, to study and potentially treat debilitating diseases such as cancer, diabetes and metabolic disorders. A study, published …
Gene therapy can viably treat mice with tuberous sclerosis complex, shows study Kumar Jeetendra | January 9, 2021 Patients with tuberous sclerosis complex, a genetic disorder characterized by the growth of noncancerous tumors in several organs of the body, have limited treatment choices. A team led by investigators at Massachusetts General Hospital (MGH) has shown that gene therapy can effectively treat mice that express one of the mutated genes that cause the disease. …
Analysts recognize interface among ALS and collection of DNA-RNA hybrids in the genome Kumar Jeetendra | January 13, 2021 Researchers from the University of Seville and the University of Pavia have identified a connection between Amyotrophic Lateral Sclerosis (ALS) and the accumulation of DNA-RNA hybrids in the genome. The accumulation of these hybrids causes increased genomic damage and boosts genetic instability. This finding will make it possible to better understand the molecular basis of …
The Cancer Microbiome Atlas gives more clear picture of microbiota living in organs Kumar Jeetendra | January 14, 2021 Biomedical engineers at Duke University have devised an algorithm to remove contaminated microbial genetic information from The Cancer Genome Atlas (TCGA). With a clearer picture of the microbiota living in a variety of organs in both healthy and cancerous states, researchers will now have the ability to find new biomarkers of disease and better understand …
Research finds new proof about the systems controlling skin repair and regeneration Kumar Jeetendra | January 19, 2021 As the air continues to dry and temperatures drop, the yearly battle against dry hands and skin has officially begun. New research from Northwestern University has discovered new evidence deep within the skin about the mechanisms controlling skin renewal and repair. Skin’s barrier function gives it the unique ability to fight winter woes and keep …
Scientists find uncommon hereditary disorder that influences the brain, heart and facial highlights Kumar Jeetendra | January 21, 2021 Researchers at the National Institutes of Health have discovered a new genetic disorder characterized by developmental delays and malformations of the brain, heart and facial features. Named linkage-specific-deubiquitylation-deficiency-induced embryonic defects syndrome (LINKED), it is caused by a mutated version of the OTUD5 gene, which interferes with key molecular actions in embryo development. The findings indicate …
New upkeep treatment for AML shows solid advantage for patients Kumar Jeetendra | January 23, 2021 Patients with acute myeloid leukemia (AML), the most common form of leukemia in adults, that has gone into remission following initial chemotherapy remain in remission longer and have improved overall survival when they are given a pill form of the cancer drug azacitidine as a maintenance therapy, based on a randomized, international phase 3 clinical …
