Jude Children’s Research Hospital scientists have developed a highly efficient method to address a major challenge in biology–identifying the genetic ‘switches’ that regulate geneexpression. Credit: St. Jude Children’s Research Hospital St.
A University of Minnesota Twin Cities-led team has developed a new technique that allows scientists and engineers to, for the first time, visualize mRNA molecules in the brains of living mice.
Researchers in the US have developed an artificial intelligence-based tool that is able to predict COVID-19 symptoms and suggest which FDA-approved drugs might be used to treat patients. The tool meanwhile could also be applied to new outbreaks of other novel viral infections as they emerge, according to the scientists.
Credit: Nucleic Acids Research Scientists at Tokyo Institute of Technology decipher how to quantitatively assess the effects of specific epigenetic changes on the rate of transcription by developing a mathematical model. For this, they successfully generated reconstituted chromatin bearing histone modifications in vitro.
The 2024 Nobel Prize in Physiology or Medicine has been awarded to American scientists Victor Ambros and Gary Ruvkun for their groundbreaking discovery of microRNA (or miRNA) and its role in post-transcriptional gene regulation. A gene contains instructions within our DNA.
Researchers at the University of North Carolina at Chapel Hill and the UNC Lineberger Comprehensive Cancer Center have uncovered a new role of a chromatin-modulatory enzyme, termed EZH2, during cancer development. They then developed a new therapeutic approach with a potent small-molecule inhibitor of this enzyme.
Researchers at the University of California San Francisco (UCSF) and the Whitehead Institute have developed a novel CRISPR-based tool called “CRISPRoff” that can switch off genes in human cells through epigenetic editing without altering the genetic sequence itself. It’s a great tool for controlling geneexpression.”.
Scientists discover small RNA that regulates bacterial infection People with weakened immune systems are at constant risk of infection. Abell Chair in Molecular and Cellular Biology – and Pengbo Cao, a postdoctoral researcher in Whiteley’s lab, discovered a gene that drives the switch. aeruginosa infections.
The dark genome – a loose term that covers non-coding regions of the genome that are capable of regulating the expression of genes, previously rather inaccurately referred to as junk DNA – is increasingly being explored by biopharma companies for new drug targets.
bluebird bio is to ask regulators to restart clinical studies of its LentiGlobin for sickle cell disease, after an investigation concluded that a case of acute myeloid leukaemia (AML) was “very unlikely” to be caused by the gene therapy. bluebird bio’s Philip Gregory.
Scientists from the German Cancer Research Center (DKFZ) and the Medical Faculty Mannheim, Heidelberg University, have now identified a new growth factor produced by blood vessels that enables tumor cells to metastatically colonize organs. In fact, scientists were able to slow the metastatic growth of breast and lung tumors in this way.
Researchers at the University of California San Francisco (UCSF) and the Whitehead Institute have developed a novel CRISPR-based tool called “CRISPRoff” that can switch off genes in human cells without editing the genetic sequence itself. These modifications regulate geneexpression without altering the sequence or structure of DNA.
It is believed to be involved in the development of chronic inflammatory intestinal diseases, to trigger diabetes, to be responsible for obesity, even neurological diseases such as multiple sclerosis and Parkinson’s could have their causes here – not to mention depressions and autistic disorders.
The approach will allow researchers to understand the role individual genes play in normal cell growth and development, in aging, and in such diseases as cancer, said Shiri Levy, a postdoctoral fellow in UW Institute for Stem Cell and Regenerative Medicine (ISCRM) and the lead author of the paper. it can be reawakened.
Born in 1970, the British and American research scientist has been Director of the Department of Microbiome Research at the Max Planck Institute for Developmental Biology in Tübingen since 2016. We are very pleased to honor today a true pioneer and outstanding scientist in microbiome research.”. The Otto Bayer Award.
Recent advances in DNA sequencing technologies have led to significant developments in healthcare-focused research on precision medicine and diagnostics. According to a study, around 20,000 genes are present in the human body, all of which interact with the nutrients in the food, either directly or indirectly.
Physician and researcher Dr. Daniel L Marks discusses the historial challenges to developing a therapeutic for this condition and what may finally be on the horizon. . However, developing an effective drug compound that can reach MC4 has been challenging because any such compound will need to be able to cross the blood-brain barrier.
Much of the fundamental groundwork for genetics and genomic research was laid in the 20 th century, with significant contributions from women scientists, some of whom worked during times when acceptance of female researchers was not widespread. She then set off to Cambridge with a fellowship she received to do research in physical chemistry.
Focusing on biologics, vaccine development and policy platforms in anticipation of an eventual outbreak is why we’re where we are today in terms of the positive side [of the pandemic].”. Most antibody drugs and vaccines have been developed to target parts of the spike protein. Pandemic Efforts.
UCSF scientists found that having an additional copy of the sex chromosome gives women two “doses” of a gene found only on that chromosome. Women live longer than men with Alzheimer’s because the extra copy of the gene on the additional X chromosome provides protection against some of the devastating effects of the disease.
