Allison Berke makes the case for real-time DNA sequencing and AI tools to detect pathogens before they spread widely. Reading DNA The first step in detecting a novel pathogen is recognizing it as an anomaly amidst a noisy background of other material. After copying the DNA to form a big pool, each piece is sequenced.
And unlike traditional DNA sequencers, which parse genetic material by breaking it up into fragments and interpreting it chunk-by-chunk, a nanopore device unspools a long strand of DNA and reads it all at once. A scientist can isolate DNA and load up a flow cell in fifteen minutes. Nanopore devices work incredibly fast.
Genome engineering and gene therapies that manipulate DNA sequences in cells have driven a biotechnological revolution over the past decade. Nature Communications 6 , 6246 (2015). 1 Adeno-associated virus (AAV) vectors are the leading platform for in vivo gene delivery for the treatment of various human diseases. Münch RC, et al.

Clonal hematopoiesis of indeterminate potential and its distinction from myelodysplastic syndromes.
Diagnosis began to shift from a body-part basis to a molecular one, which I wrote about in “Mutation and location important in cancer treatment” for The Lancet in 2015. Analyzing DNA patterns using AI may replace time-consuming process DNA and genomic sequencing tests, Yu said.
billion bases of DNA which, if unfurled, would extend for more than 100 meters—taller than the Statue of Liberty. billion bases of DNA, the human genome measures just 2 meters in length when stretched end-to-end. Credit: Oriane Hidalgo Per the book Cell Biology by the Numbers , each base pair of DNA occupies 1 nm 3 of space.
5 Cytology-based profiling can facilitate antibiotic discovery efforts and, these assays assess cell cycle progression, nuclear and mitochondrial DNA content, mitochondrial DNA replication, nuclear DNA damage, mitochondrial membrane potential, and lysosome structure and function. and Wolfgang, H. Gabriela, S. Andreas, B.,
By 1984, he and Brookhaven colleague John Dunn successfully identified and cloned the protein within T7 that was responsible for rapidly copying T7 DNA into many corresponding strands of RNA — a critical step in the bacteriophage’s ability to infect E. coli genome and let the E. coli had no built-in way to shut it off.
Einstein predicted the existence of gravitational waves in 1916, but LIGO did not detect them until 2015. This last variable could be just about anything; there are proteins that bind to other proteins (like antibodies), cut other proteins (proteases), or bind DNA (transcription factors). Synthesizing that much DNA is cost-prohibitive.
2 AlphaFold 3 has been built to model DNA, RNA and smaller molecules (ligands). Google DeepMind’s new AI can model DNA, RNA, and ‘all life’s molecules’. There are several technologies and specific tools being rolled out in this area. The latest exciting advancement is AlphaFold 3, which was just released. Alphafold 3.0:
The two companies have been in a strategic research collaboration agreement since 2015, focused on using CRISPR Cas-9 to discover new potential treatments. Cas-9 represents the Cas9 protein, an enzyme that cuts foreign DNA. Once the DNA has been cut, the cell’s natural repair mechanisms kick in. ” Source link.
That was so in 1977, when “intervening DNA sequences” – aka “introns” – were discovered to interrupt protein-encoding genes. Because the edits are in RNA, and not DNA, they are fleeting. The post How (and Why) the Octopus Edits its RNA appeared first on DNA Science.

The specific proteins found in these aggregates can vary, but approximately 95 percent of ALS patients and 50 percent of FTD patients develop aggregates containing the TDP-43 protein (short for tar DNA binding protein 43). 14 TDP-43 is a DNA and RNA binding protein that regulates the expression and splicing of several target transcripts.
2 In response, DNA-damaging agents that could target the entire cell cycle received renewed attention as ADC payloads. DNA damaging agent-based antibody-drug conjugates for cancer therapy. While highly effective against proliferating tumour cells, ADCs with antimitotic payloads typically struggled against slower-growing cancer types.

Most cells (excluding T-cells and B cells after V(D)J recombination) in our body contain the same DNA but appear and behave in distinct ways: A neuron looks and acts very differently from a hepatocyte. While DNA is relatively stable , the epigenome is not; it has to orchestrate changes in cell state, cell type, and more.
Comparing genome sequences is important because they provide a 4-letter language in the bases A, C, G, and T (for DNA) or A, C, G, and U (for RNA). The agency started tracking it in 2013, and the spread accelerated in 2015. The post The New Fungus Among Us, Candida auris appeared first on DNA Science.
