Junk DNA: How the dark genome is changing RNA therapies

Drug Discovery World

Samir Ounzain , PhD, CEO & Co-Founder of HAYA Therapeutics, looks at how a better understanding of our DNA can lead to increased activity for RNA therapeutics. The whole world realised the power of RNA when the Covid-19 pandemic brought us the first mRNA-based vaccines.

A new dawn of the genomic age: five areas set to be transformed in 2023

pharmaphorum

2022 was a banner year for genomics. In March, the collaborative T2T consortium published the first complete telomere-to-telomere sequence of the human genome, filling in the last 8% of the 3 billion base pairs that make up our DNA.

Why genomic healthcare data matters in the development of new therapies 

Drug Discovery World

Genomic healthcare data is critical to identify disease risk, ancestry, traits and response to medicines and aids in the development of new targeted therapies – precision medicines. In April 2003, after its launch in October 1990, the project was completed, generating the first sequence of the human genome. The origins .

Why Proviral DNA Drug Resistance Testing is Useful in Guiding Treatment Decisions for HIV-1 Patients

XTalks

Compared to standard plasma HIV-1 RNA drug resistance profiling, which requires a viral load of at least 500 copies per mL, proviral HIV-1 testing can be performed on samples with much lower virion counts of <50 copies per mL (below the detectable limit in RNA testing). Proviral DNA Genotyping. HIV Drug Resistance Testing.

Epigenetics discovery could lead to new class of cancer drugs

Drug Discovery World

Epigenetics is still largely unexplored and referred to as the ‘dark matter’ of the genome. But, until now, scientists lacked an understanding of what the chemical tag does, despite many years of research. When it gives the green light, H3K4me3 allows RNA polymerase II to move along DNA, transcribing it into RNA as it moves.

AI-designed protein awakens silenced genes, one by one

The Pharma Data

“The beauty of this approach is we can safely upregulate specific genes to affect cell activity without permanently changing the genome and cause unintended mistakes,” Levy said. PRC2 can be blocked with chemicals, but they are imprecise, affecting PRC2 function throughout the genome.
