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 locate mechanism underlying plasticity in grownup brains Kumar Jeetendra | December 27, 2020 Developing brains continuously sprout new neuronal connections called synapses as they understand and remember. Important connections — the ones that are repeatedly introduced, such as how to avoid danger — are nurtured and reinforced, while links deemed unnecessary are pruned away. Adult brains experience similar pruning, but it was unclear why or how synapses in …
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 …
Enormous transporter protein dysfunction related with schizophrenia Kumar Jeetendra | December 29, 2020 Researchers have suspected mutations in a cellular cholesterol transport protein are associated with psychiatric disorders, but have found it hard to show this and to pinpoint how it happens. Currently, Kazumitsu Ueda of Kyoto University’s Institute for Integrated Cell-Material Sciences (iCeMS) and colleagues in Japan have provided evidence that mice with disrupted ABCA13 protein demonstrate …
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 build up a little, yet successful technique for forestalling premature birth Kumar Jeetendra | January 14, 2021 In a study in mice and human cells, Johns Hopkins Medicine researchers say that they have developed a little, yet effective method for preventing premature birth. The vaginally-delivered treatment contains nanosized (billionth of a meter) particles of drugs that easily penetrate the vaginal wall to reach the uterine muscles and keep them from contracting. If …
Inflammation may add to the determination of C. diff disease, shows study Kumar Jeetendra | January 19, 2021 A new study from North Carolina State University indicates that the inflammation brought on by Clostridioides difficile (C. diff) infection gives the pathogen a two-fold advantage: by both creating an inhospitable environment for competing bacteria and supplying nutrients that enable C. diff to thrive. C. diff is a bacterium that causes diarrhea, often with severe …
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 …
UC research group utilizes zebrafish to contemplate a quality change that causes intrinsic scoliosis Kumar Jeetendra | January 24, 2021 Popular in aquariums throughout the world, the zebrafish is native to South Asia. But here in a Cincinnati Children’s laboratory, the freshwater variant plays a vital role in scientific discovery. The patterning of the zebrafish’s spine gives the appearance of stripes; it is controlled by segmentation genes which function as a clock. Zinani is part …
World’s first completely reversible control of the circadian clock Kumar Jeetendra | January 26, 2021 The Nagoya University Institute of Transformative Bio-Molecules (WPI-ITbM) research team of Designated Associate Professor Tsuyoshi Hirota, Postdoctoral Fellow Simon Miller, Professor Kenichiro Itami and grad student Tsuyoshi Oshima (Research Fellowship for Young Scientists, JSPS), in collaboration with the team of Professor Ben Feringa and Postdoctoral Fellow Dušan Kolarski of Groningen University in the Netherlands, have …
