Regulatory Guidance for Oligonucleotide Bioanalysis in DrugDevelopment pmjackson Wed, 02/19/2025 - 21:30 The unique physicochemical properties of oligonucleotides require the use of specialized bioanalytical approaches, with key considerations including selectivity and specificity, sensitivity, stability, and matrix effects.
Beyond Proteins: DNA and RNA Frontier The story doesn’t end with proteins. DNA and RNA are also key players, each bringing unique challenges. Many cancer treatments target DNA, but often these can cause collateral damage, leading to severe side effects.
It “could have been easily repurposed for DMD,” said Pier Lorenzo Puri at Sanford Burnham Prebys Medical Discovery Institute in San Diego, who has been working on the drugdevelopment since 2004. MDA supported development of a mouse model that enabled the preclinical studies of what would become Duvyzat.
Five Promising Treatment Areas in Early-Phase DrugDevelopment in 2024 aasimakopoulos Wed, 04/17/2024 - 15:52 Early-phase drugdevelopment is an ever-changing landscape, as emerging science leads to new promising areas of research for the treatment of human health issues.
Its structure makes it incredibly difficult for drugs to bind effectively, which has stymied drugdevelopment for decades. The binding pockets on KRAS are shallow and polar , not ideal for the kinds of interactions needed for strong, effective drug binding.
Inside The Altascientist: The Benefits of PCR for Your Gene Therapy Programs pmjackson Tue, 04/16/2024 - 19:04 The gene therapy landscape continues to accelerate in preclinical and clinical research, with programs constantly in development for targeted, personalized medicines. But how are PCR analysis techniques applied?
This was the first successful drugdevelopment against a transcription factor, opening the door to targeting a whole new class of previously unreachable targets. The Promise of Multispecific Drugs The future of drug discovery looks even brighter with the development of multispecific drugs.
In a previous study, we showed that these peptides decorate all cellular RNAs and thus impair the binding of RNA-binding proteins to RNA. For his postdoctoral stay he joined the group of André Nussenzweig, where he started to work on DNA repair, particularly focusing on the role of histone H2AX.
It has become a fundamental tool for researchers to explore the complexities of genetic information and conduct genetic-informed drugdevelopment. Sponsors have used NGS to screen patients for clinical trial eligibility and patient stratification , expanded CDx development, and comprehensive genomic profiling (CGP).
Molecular Biomarkers : Encompass various molecules, such as RNA and metabolites, to reflect the physiological state of the cells and their disease pathways. The analysis of circulating tumor DNA (ctDNA) in a liquid biopsy can also permit genotyping and help monitor the effectiveness of chemotherapy.
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.
Companies are planning their drugdevelopment strategies with automated unit operations in mind, and how to incorporate them earlier in the development pipeline. Throughout his career in the industry, Dalip has been engaged in developing technologies and methods for use in cell therapy applications.
Harini joined Serna Bio in early 2021 and has been an integral part of the multidisciplinary teamworking on target ID platform development to drug discovery. She has played a key role inbuilding the target identification platform and a proprietary database of transcriptome-wide, functional RNA structures.
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).
The method prevents the mouse’s immune system from rejecting the CRISPR machinery while also leaving behind RNA barcodes that can be sequenced to determine which gene had been deactivated in each cell. “I
Dear readers, RNA, or ribonucleic acid, plays a pivotal role in the intricate dance of cellular processes. We are committed to providing you with the highest quality content, and we believe that this report will deliver a different perspective on the topics covered.
But, regardless of which was first, they all operated with the same core data as their mechanism for understanding life: messenger RNA ( mRNA ). It wasn’t a silver bullet to the hard problem of drugdevelopment, but it wasn’t too far off either. A flurry of new, promising therapeutic targets arose.
HTRF is a common in-vitro assay modality used in drugdevelopment. Amplified luminescent proximity homogeneous assays, or Alpha assays, measure response to non-radioactive fluorescent emission by tagged molecules located near the target molecule.
As an undergraduate biology student, I spent some time in a TB lab working on antibiotic resistance — a growing concern for drugdevelopers. Some fluoroquinolones — a class of antibiotics that inhibits DNA replication — may even cause psychosis. The researchers were left with 40 drug candidates.
This gene-editing system consists of a short segment of RNA that is attached to an enzyme. The RNA is preprogrammed to find a distinct short sequence of DNA and deliver the enzyme, which acts like a scalpel to slice the sequence out of the genome. It’s fast and pretty precise.
