Credit: Surajit Chatterjee To better understand how RNA in bacteria gives rise to protein–and along the way, target these processes in the design of new antibiotics–researchers are turning their attention to the unique way this process happens in bacteria.
coli enzyme synthesizing ribosomal RNA that shift it between turbo- and slow-modes depending on the bacteria’s growth rate Credit: Murakami Laboratory, Penn State The enzyme that makes RNA from a DNA template is altered to slow the production of ribosomal RNA (rRNA), the […].
Perhaps popularized by the COVID-19 vaccines, RNA-based technologies now have the potential to become the next best pesticide to combat crop pests, like insects and fungal pathogens. Over the last year, researchers have been studying the effectiveness of RNA-based pesticides, and there are already a handful of sprays in the works.
In a study published in The Lancet Microbe, the researchers linked RNA mutations within the bacterium Neisseria meningitidis to invasive meningococcal disease, […].
Beneficial bacteria, called rhizobia, form an intimate interaction with legumes, inducing the formation of symbiotic root nodules in which bacteria fix nitrogen and provide the plant with an […]. Plants encounter microbes all the time, in the air, water, and soil.

The RNA Revolution: From mRNA Vaccines to RNA Editing. The age of RNA is officially here, and it’s here to stay as more than a passing life science trend. RNA technology is not new nor has its potential been surprising. RNA in the Making. So why did this perceived RNA ‘revolution’ take so long?
Viruses and bacteria can be first modified to prevent them from causing infectious diseases and then implemented into human tissues as therapeutic gene vectors. For example, it is beneficial to administer RNA treatments for some lung diseases directly to the disease site through inhalation. Route of Administration Considerations.
Scientists discover small RNA that regulates bacterial infection People with weakened immune systems are at constant risk of infection. But the bacteria can sometimes change their behavior and enter the bloodstream, causing chronic localized infections to become acute and potentially fatal. aeruginosa infections.
Study describes new mechanism for terminating transcription of DNA into RNA in bacteria Credit: Babitzke Laboratory and Dani Zemba, Penn State The protein, known as NusG, pauses the transcription machinery at specific DNA sequences to facilitate what is called “intrinsic termination” and prevent unwanted transcription that could disrupt (..)
A naturally occurring system for tuning CRISPR-Cas9 expressing in bacteria, identified in a study published in Cell , could have implications for gene editing therapies as well. A CRISPR-Cas9 system has two components: the Cas9 guide RNA that directs the system to edit a particular gene, and the CRISPR “scissors” that make the cut.
Although at 90% effectiveness AZ’s shot would lag slightly behind RNA-based rivals from Pfizer/BioNTech and Moderna, AZD1222 is easier to handle and can be stored in fridges instead of at ultra-cool temperatures.
The CRISPR-Cas9 gene editing system uses a programmable single guide RNA sequence (sgRNA) to find and bind to specific regions of DNA and the Cas9 nuclease induces double strand breaks at these target regions of the genome. Integrases are used by viruses called bacteriophages to insert their genetic material into bacteria.
These are the cells that have the potential to form a new tumour mass at a later stage” explains cancer researcher and RNA biologist Eleonora Leucci (KU Leuven).
Membrane Filters: Membrane filters are typically used for sterilization and removal of smaller impurities such as bacteria and viruses. It removes bacteria, viruses and other debris using microfiltration, ultrafiltration and nanofiltration. are used to remove any residual bacteria, viruses, or endotoxins.
The company’s suite of market-leading molecular profiling offerings assesses DNA, RNA and proteins to reveal a molecular blueprint that helps physicians and cancer patients make more precise and personalized treatment decisions.
Respiratory infections are caused by a good sort of pathogens, like influenza viruses, respiratory syncytial virus, parainfluenza viruses, metapneumovirus, rhinovirus, enterovirus, coronavirus and adenovirus, and other bacteria pathogens.
coli bacteria, as well as lambda bacteriophage, can adapt to the alterations in the composition of their nutrient medium. It is worth noting that the transcription factor is responsible for recruiting RNA polymerase to bind to the gene and produce messenger RNA, which is then translated into the protein.
coli bacteria. The bacteria are grown in large vats, with the process taking two weeks. The RNA is transcribed from DNA in 40-liter vessels containing enzymes and chemicals over the course of three to four days. Vaccine mRNA: The DNA is then shipped 1,200 miles over to the Andover plant from which mRNA is synthesized.
Pneumococcal disease is an infection caused by bacteria called Streptococcus pneumoniae, or pneumococcus. Different strains of this bacteria are called serotypes. Invasive pneumococcal disease (IPD) occurs when the bacteria infect parts of the body that are usually free from germs.
2) Botox Therapeutic/Cosmetic Botox, or botulinum neurotoxin, is a neurotoxic protein produced by the Clostridium botulinum bacteria. 2) Veklury (remdesivir) Veklury, approved by the FDA in 2020, is a SARS-CoV-2 nucleotide analog RNA polymerase inhibitor designed for the treatment of COVID-19. billion in 2022. billion in 2022.
Doudna, PhD, of the University of California, Berkeley and Emmanuelle Charpentier, PhD, of the Max Planck Unit for the Science of Pathogens Institute for Infection Biology, revolutionized genetic research by helping to identify a natural gene editing mechanism in bacteria. Single-Cell RNA Sequencing.
The journey began in 2000 with the FDAs approval of the first pneumococcal conjugate vaccine, PCV7 (Prevnar), which quickly became a routine immunization for children in the US, protecting against seven serotypes of pneumococcal bacteria. of patients on Genvoya and 80% of those on Stribild achieved HIV-1 RNA levels below 50 copies/mL.
