A team led by researchers at Baylor College of Medicine and the Czech Academy of Sciences has uncovered a new piece of the puzzle of how geneexpression is orchestrated. Published in the journal Science, the findings reveal a novel mechanism that coordinates the assembly of components inside cells that control geneexpression.
The function of a protein can depend on its abundance in a cell. So, when investigating the properties of a new protein, it is essential to make sure that the same amount is produced by every cell. Researchers at Baylor College of Medicine and Rice University have found a new way to do just that […].
A form of blood cancer known as mantle cell lymphoma is critically dependent on a protein that coordinates geneexpression, such that blocking its activity with an experimental drug dramatically slows the growth of this lymphoma in preclinical tests, according to a study from Weill Cornell Medicine researchers.
Biotechnology, Pharma and Biopharma News – Research – Science – Lifescience ://Biotech-Biopharma-Pharma: Study highlights role of disordered protein interactions in gene expression.A
Brazilian research group shows that valproic acid (VPA), used to treat epilepsy since the 1960s, modulates geneexpression in tumor gene models and acts on DNA conformation and the histones in chromatin Results of recent studies involving valproic acid, used for decades as an anti-convulsant drug, show that it can interact with the conformation of (..)
Mount Sinai researchers have discovered that Polycomb complexes, groups of proteins that maintain geneexpression patterns, are essential for proper skin development, according to a paper published in Genes & Development on February 18.
The detailed complexity of these processes can be captured by creating models that combine correlates of gene and proteinexpression, providing insight into the molecular composition of tissues. Visium Spatial GeneExpression Solution. Feature barcoding using gel beads. Single Cell Data Analysis.
By combining CRISPR technology with a protein designed with artificial intelligence (AI), it is possible to awaken individual dormant genes by disabling the chemical “off switches” that silence them. Researchers from the University of Washington School of Medicine in Seattle describe this finding in the journal Cell Reports.
Findings suggest one factor that may contribute to disparities in COVID-19 infection New York – In a study published in JAMA today, Mount Sinai researchers report findings that shed some light on the disproportionate impact of COVID-19 on Blacks, who have experienced rates of infection and death that are much greater, in some areas twice […]. (..)
Study shows that tumor-suppressor protein p53 brings speckles and DNA together to boost geneexpression PHILADELPHIA – A team led by scientists at the Perelman School of Medicine at the University of Pennsylvania has illuminated the functions of mysterious structures in cells called “nuclear speckles,” showing that they can work in (..)
Cutting edge’ is, for once, a truly apt description when it comes to gene editing – both because the field is pushing medicine into areas we might never have dreamed possible, and because these technologies involve literally cutting DNA at a specific point in the genome. The genomic medicine journey.
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. Last year’s Nobel Prize in Physiology and Medicine also went to RNA researchers.
UNC researchers now show that these two factors can directly associate with one another, modulating cancer-cell-specific programs of geneexpression. ” They found that EZH2 possesses two different binding patterns on chromatin in acute leukemia cells, eliciting two distinct gene-regulatory programs (Figure 1). .”
In a field quickly gaining attention for its role in vaccine development and personalized medicine, Elixirgen Therapeutics stands out through its pursuit of innovation and safety. ZSCAN4 and Telomere Biology Disorders The ZSCAN4 gene produces a protein that plays a crucial role in maintaining telomeres.
Beta catenin meanwhile is a signalling protein in the Wnt pathway – in particular a downstream transcription factor (TCF) implicated in a range of solid tumour types including colorectal, liver, breast, prostate, uterus and lung cancers.
In fact, biologics are anticipated to play a significant role in shaping the pharmaceutical industry and will eventually serve as an integral part of traditional medicines. Overview of Biologics Biologics refer to medicinal / therapeutic products that are either manufactured using living organisms or semi-synthesized from biological sources.
Molecular diagnostic solutions are pivotal across various medical fields, including oncological disorders, infectious diseases, genetic testing, and personalized medicine. Such test can be used for geneexpression profiling, genotyping and detecting chromosomal abnormalities.
Coding RNAs include messenger RNA (mRNA) and short interfering RNA (siRNA), which encode proteins and silence geneexpression, respectively. ASOs are short single-stranded nucleotides that bind to specific messenger RNAs and prevent the production of a particular protein.
The drug, UCB0107, is designed to impede or decrease the buildup of tau proteins in the brain, which leads to nerve cell damage and death. It will push a pipeline of treatments toward the clinic as well as bankroll the recognition of new targets for genomic medicines. Omega Therapeutics is getting a USD 85 million cash boost.
” With a particular focus on the lung, the researchers performed global geneexpression analyses of the metastatic niche. They discovered that in the presence of a primary tumor, the endothelial cells lining the interior of blood vessels produced the protein LRG1 (leucine-rich alpha-2-glycoprotein 1) in large quantities.
Studies have identified the presence of two types of HIV-infected CD4+ T cells: ‘Transcriptionally inactive’ cells that do not typically produce viral RNA or viral proteins. Fucosylation is the attachment of a specific sugar molecule called fucose to proteins on the surface of cells. T Cell Glycomic Signatures in HIV.
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.
In addition to pharma and biotech companies who zealously began working to develop COVID-19 drugs and vaccines, companies from areas outside of science and medicine also stepped up to help during the pandemic. Most antibody drugs and vaccines have been developed to target parts of the spike protein.
Geneticist Martha Chase was a key partner of the foundational Hershey-Chase experiment that helped confirm DNA to be the carrier of genetic information; however, it was only Hershey of the pair that went on to win the Nobel Prize in Physiology or Medicine in 1969 for the discovery. Martha Chase.
It helps explain why women with the disease survive longer with less severe symptoms than men during the early stages of the Alzheimer’s, despite having the same levels of toxic amyloid beta and tau proteins in their brains. The study was published in the journal Science Translational Medicine. KDM6A Variant.
The goal of the company’s cancer research is to deliver medicines that offer each patient a better, healthier life and to make cure a possibility. HDACs catalyze the removal of acetyl groups from acetylated lysine residues in histones, resulting in the modulation of geneexpression.
