For my PhD project, I chose an advisor who worked on DNA and I started working with her on the physical properties of DNA. I worked with Jackie Barton in the early days of what’s now called DNA-mediated electron transfer. It’s just a phrase for things that haven’t yet been drugged.
Webinar | Ai At The Frontier: Empowering Early Career Professionals In Drug Discovery WEBINAR – ARE YOU CURIOUS ABOUT THE CUTTING-EDGE INTERSECTION OF ARTIFICIAL INTELLIGENCE AND DRUG DISCOVERY? Are you curious about the cutting-edge intersection of Artificial Intelligence and Drug Discovery?
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. More recently, the group has expanded to other areas such as mechanisms of drug resistance and neurodegenerative diseases.
The general notion is that patients should be viewed individually, rather than strictly as members of some larger general population, and that their specific genetic background, environment, and lifestyle choices should be considered throughout drug development to the point of treatment and continuing patient care.
The bulk of my nearly three decades of experience up to that point was with drugging protein targets using a variety of modalities, but principally small molecules. It’s all well and good to say, “we should drug RNA,” but which RNA? And unproductive interactions between the RNA target and the DNA barcodes complicated DEL screening.
As such, it has been proposed that inhibiting CDK7 would provide a potent means of inhibiting cell cycle progression, which may be especially relevant given that there is compelling evidence from gene knockout studies in mice for lack of an absolute requirement for CDK2, CDK4 and CDK6 for the cell cycle at least in most cell types (M alumbres et al.,
By Allessandra DiCorato October 11, 2023 In 2011, Robert Manguso was working in a cellbiology lab when his mother was diagnosed with Merkel cell carcinoma, a rare and aggressive skin cancer. They are used to treat cancers including melanoma and non-small cell lung cancer, but work only for a small fraction of patients.
Cardiovascular diseases are the leading cause of mortality worldwide, and traditional approaches like drug therapy or invasive procedures manage symptoms but do not restore lost cardiac tissue. Continued growth in the field relies on multidisciplinary efforts combining biology, engineering, and clinical medicine.
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. They tend to “group up” in cells. Molecular Systems Biology. Nature Microbiology. Meeussen J.V.W.

DNA, proteins, polysaccharides, etc.). Cells require energy for this process. 2 Organisms are categorised based on their anabolism and according to the source used by cells to build-up molecules. In anti-tumor therapy development, this effect is a main focus of drug discovery. nucleotides, monosaccharides, etc.),
Sponge cells double in population quite quickly — around 40 minutes — and could be engineered to manufacture drugs. ” This technology could be used to design protein therapeutics that can bind to, and “shut down,” harmful or misfolded proteins in living cells. Nature CellBiology.
During this process, the cells’ genomes ditch their methyl groups, an important epigenetic mark. Erasing methyl groups on DNA is necessary for normal egg and sperm development. Reaching the oogonia stage marked an impressive achievement in germ cellbiology, because previous methods only went up to the PGC stage.
Short DNA strands were discovered that can specifically and tightly bind to zinc and cadmium ions. Perhaps there is now a way to use DNA to extract metals: You could fuse the DNA strands to an antibody, coat them onto electronics, and then use a column to isolate the DNA:metal compounds?

Researchers identify source of a brain cancer’s deadly transformation By Corie Lok November 21, 2024 Breadcrumb Home Researchers identify source of a brain cancer’s deadly transformation Slow-growing glioma tumors become more aggressive when their cells shift identities and acquire new genetic mutations.
For example, cloning DNA molecules and inserting them into cells — a process required for basically all experiments in molecular biology — takes up to a week of work. But looking ahead to the second bottleneck, what does it mean to say that biology is “complex”? Even the humble E.
