Founding Vision: Harnessing RNA Editing for Transformative Medicine Korro Bio’s story began in 2018, co-founded by a remarkable group: Jean-François Formela, M.D. Academic specializing in RNA editing). The ability of modifying RNA enabled us to sidestep many of the potential risks associated with permanent DNA editing.
I also walked attendees through some of our DNA and RNA isolation techniques and our molecular biology laboratory’s experience in collecting samples and isolating genetic material to assess germline integration after preclinical studies.
Whether it is determining concentrations of molecules like proteins or DNA, looking at enzyme kinetics for crucial reactions, or measuring something as fundamental as cell growth, you will find references to absorbance or optical density measurements. But how do they relate to each other? Lets start by looking at some definitions.
Dwarves aren’t made out of individual cells; they don’t have DNA (yet), though they do have eyelids. Its explanatory power wasn’t even reliant on DNA. Even if an understanding of DNA wasn't necessary to come up with the theory of evolution, genes and their underlying pieces are very mechanistic.
We’ll cover the common terminology for the proteins, DNA, and RNA used in CRISPR. CRISPR is an elegant bacterial immune system and an efficient gene editing tool… but boy does it have a lot of parts! If you’re still a bit confused by CRISPR acronyms, this post is for you.
Prime editing is a versatile genome editing technology that allows precise modifications of DNA (replacements, small insertions, and deletions) without introducing DNA double-strand breaks (Anzalone et al., 2019; Chen & Liu, 2023).
Prior to 2015, I had a casual relationship, at best, with targeting RNA. Targeting RNA is a Whole New World Then in 2015, I became smitten and eloped with RNA, setting out to build a company devoted to bringing to bear industrial drug discovery concepts and methods on a new problem of drugging RNA with small molecules.
Our overall mission at Arrakis is to expand the set of “druggable” targets for small-molecule medicines to include RNA. Today, we are pleased to announce that our article describing one such platform: “ PEARL-seq, A Photoaffinity Platform for the Analysis of Small Molecule-RNA Interactions ” was published in ACS Chemical Biology.
These numbers reflect impressive developments in DNA sequencing technologies but in most cases represent the immediate costs of consumables on the sequencing instrument. 2 DNA sequencing is also reliant on sample processing and DNA library preparation before sequencing as well as bioinformatics and data analysis after sequencing.
As soon as I learned about DNA and RNA, I wanted to be a molecular biologist. Last stops at RNA My last roles in biotech were where my original passion began: DNA and RNA. My last stop at Arrakis Therapeutics is with a company targeting RNA with small molecules. Arrakis is the capstone of my career.
The steps taken during the analytical phase are dependent on the type of biomarker, which can range from DNA, RNA, protein, peptide, biomolecular modification(s), or biochemical pathway(s). The post Breaking Down Biomarker Discovery: 5 Points first appeared on PerkinElmer Blog.
These results were corroborated by an RNA sequencing analysis we carried out in parallel, which revealed that depending on the temperature, RBM3 had different isoforms created by differential self-splicing. RBM3 is an RNA-binding protein, and we needed an RNA biologist, which is when Deepak joined the project.
The central dogma of molecular biology is that information generally (with few exceptions) flows from DNA to RNA to Protein. In my own career, starting to write a blog was one of my most impactful “Friday afternoon experiments” – I even called it an experiment in my very first blogpost back in March 2011.
We will present a fully automated end-to-end solution inclusive of automation and reagents optimized for miniaturized NGS that is guaranteed to generate high-quality libraries.
In this blog article, we review some of these areas of investigation where Altasciences has robust expertise and solution offerings. Several viral vectors are being used currently, in addition to non-viral vectors, such as oligonucleotides, naked DNA, and lipoplexes and polyplexes.
CDK7 also plays a role in transcription and possibly in DNA repair. The trimeric Cak complex CDK7/CyclinH/MATl is also a component of TFIIH, the general transcription/DNA repair factor IIH (Morgan, DO., As a TFIIH subunit, CDK7 phosphorylates the CTD (Carboxy-Terminal-Domain) of the largest subunit of RNA polymerase II (pol II).
Thanks to decades of progress in molecular sequencing technologies, it is simple to read out the order of nucleotides in a DNA sequence, for example, or to quantify messenger RNAs as they are made by a cell. Escherichia coli have about 5 million base pairs of DNA in their genome, and divide every 20 minutes.
Experiments at the Wuhan facility were done at the lowest two of the four standard biosafety levels, which were established at the dawn of recombinant DNA research in the 1970s. The Likely Predecessor of SARS-CoV-2 – From my Past Blog Posts I wrote 100+ DNA Science blog posts during the pandemic about the virus.
kb relaxed circular DNA (rcDNA) genome that is used to form covalently closed circular DNA (cccDNA) in a host cell. The cccDNA is then transcribed by RNA polymerase II, a host DNA-dependent RNA polymerase, to produce pregenomic RNA (pgRNA). HBV possesses a 3.2- The results are shown below in Tables 8 and 9.
But now, by studying DNA extracted from microbes in the blood of almost 10,000 healthy people, this paper shows that there is no such thing. Read Transcription factors bind to DNA and control gene expression. Read Switchable hydrophobic pockets in DNA protocells enhance chemical conversion. Nature Microbiology. Meeussen J.V.W.
1 One rarely pauses to ponder how so much DNA — let alone sugar, proteins, and everything else — can fit inside such a small vessel. Students learn the basics through words: DNA is transcribed to RNA, which is translated into proteins. How fast does DNA become RNA, or RNA protein? A typical E.
In 2016, her team demonstrated that, by adding short snippets of DNA or RNA — which can target and “shut down” the MaMADS regulatory proteins — to bananas, it is possible to slow their ripening. has a genome made of DNA. The idea came from tomatoes, which ripen in much the same way.) From Elitzur T.

They’ve just finished sequencing the patient’s genome, but they don’t have “DNA sorting” software. billion units of DNA code are transcribed into more than a hundred volumes, each a thousand pages long, in type so small as to be barely legible.” LEGO robot to make sucrose gradients.

Yeast die for two reasons: Either their nucleolus (where the DNA is kept) degrades and dies, or their mitochondria whimpers out and they stop making energy. The vaccine printer can make lots of different types of vaccines, including protein, DNA, and mRNA ones, but I’m sure this is all quite expensive right now. From Zhang et al.

DNA sequences are designed on a computer, and it takes a dozen or more clicks to change a single nucleotide. DNA sequences are also checked by hand, so it’s easy to make a mistake. The tool outputs a DNA sequence that encodes all the required enzymes. Anyone who has tried to engineer a cell knows how tedious it can be.

Sequencing viral genome isolates and creating phylogenetic trees Sequencing a viral genome requires isolating the viral RNA, reverse transcribing it into DNA, and then performing multiple amplification steps using primers. Finally, the DNA library is sequenced, the sequences are aligned, and the full genome annotated.
Most people would take the two CRISPR gene-editing components (a Cas9 protein and guide RNA), package them up inside of a virus, and then inject the viruses into the skulls of mice. 📎 Papers Strands of DNA can be used to build molecular logic gates. Stahl et al. on bioRxiv. Nature Communications. Nature Communications.

Small snippets of double-stranded RNA were sprayed onto hot pepper plants to control a pest, called Frankliniella occidentalis. The RNA strands shut down a specific gene in the insects, and killed half after 7 days. RNA may offer a safer form of pest control in the future. The new sequences might help de-extinction efforts.
The technology can be applied to a number of different types of antibody-based assays, which are used to characterize GPCR signaling, activity of various protein kinases and other cytokines, and the interactions of certain singular proteins with each other or DNA and RNA. – [link] Wen et al.
That’s because proteins are made, in the laboratory, using synthetic DNA and cells; and DNA is expensive. Our machine would make proteins without using any DNA or cells. All cells make proteins in two steps: DNA is transcribed into messenger RNA, which is then translated into protein.
But, regardless of which was first, they all operated with the same core data as their mechanism for understanding life: messenger RNA ( mRNA ). Some emerged from a “DNA is all you need” worldview, investing heavily in better long-read sequencing and chromatin accessibility data.
Erasing methyl groups on DNA is necessary for normal egg and sperm development. The most important step seems to be erasing DNA methylation. Methyl groups attached to DNA are first artificially erased using a chemical inhibitor to mimic the erasure that happens during germline commitment.

“The recombinant DNA breakthrough has provided us with a new and powerful approach to the questions that have intrigued and plagued man for centuries. The central dogma is often depicted as DNA→RNA→protein, but it’s much more: A biophysical marvel inside the smallest of vessels. Biology is a Burrito.
