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 generegulation. However, microRNAs can bind to this mRNA, preventing it from functioning.
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.
RNA therapeutics are a novel class of biopharmaceuticals that harness the power of RNA molecules for the treatment and prevention of a wide range of disorders, including oncological, and genetic disorders as well as infectious diseases. Non-coding RNAs include antisense oligonucleotides (ASOs) and RNA aptamers.
Innovation S-curve for the pharmaceutical industry Transcription factors for genetically modified cells is a key innovation area in the pharmaceutical industry Transcription factors are proteins which control geneexpression by controlling the rate of transcription of genetic information from DNA to RNA.
Another therapy by the same company named GTX-102 is also an antisense therapy; however, it silences geneexpression by binding to the RNA molecule that regulates its expression.
These modifications regulategeneexpression without changing the sequence or structure of DNA. The CRISPR gene editing system consists of the Cas9 enzyme, which serves as molecular scissors to cleave double-stranded DNA, and a guide RNA template targeted to a specific genomic sequence, which allows for precise editing.
Mechanism of Gene Switch During the transcription process, the promoter region, which is located near the upstream end of each gene, binds to transcription factor, which is a specific type of protein. An additional level of genetic control is provided by gene switches that are located upstream of the promoter region.
InteRNA is focusing on the development of gene-silencing drugs based on microRNA, naturally occurring, non-coding strands of RNA that are thought to regulategeneexpression in cells.
In 2018, Shalev and colleagues reported the benefits of verapamil in a one-year clinical study of Type 1 diabetes patients, finding that regular oral administration of verapamil enabled patients to produce higher levels of their own insulin, thus limiting their need for injected insulin to regulate blood sugar levels.
The new technique controls gene activity without altering the DNA sequence of the genome by targeting chemical modifications that help package genes in our chromosomes and regulate their activity. The chemical modifications that regulategene activity are called epigenetic markers.
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. Transcriptionally active’ cells in which HIV RNA is actively transcribed to make copies of the virus (despite long-term ART).
These modifications regulategeneexpression without altering the sequence or structure of DNA. The CRISPR gene editing system consists of the Cas9 enzyme, which serves as molecular scissors to cleave double-stranded DNA, and a guide RNA template targeted to a specific genomic sequence, which allows for precise editing.
For instance, GTX-102 , an antisense therapy silencing the geneexpression by binding to the RNA molecule behind the regulation of its expression, has also secured USFDA Fast Track Designation. Although, it can be relieving that other players turned to different approaches for finding a cure for Angelman syndrome.
BOSTON – An important player in the healthy development of female embryos turns out also to play a key role in regulating the behavior of chromosome loops and geneexpression in both sexes, according to a new study by researchers at Massachusetts General Hospital (MGH).
BioNTech/Pfizer’s vaccine became the world’s first approved COVID-19 vaccine, with UK regulators becoming the first to authorize it for emergency use, followed by Health Canada, which fully approved it. Single-Cell RNA Sequencing. Then, the US FDA followed suit by granting it emergency use authorization (EUA) in mid-December.
