Modern advances in “omics,” as well as biomarker development, clinical trial design, and mathematical modelling (including artificial intelligence) have revolutionized our ability to precisely define or “stratify” patient populations, splitting them into groups based on their characteristics.
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. By then, a few cancer immunotherapies had entered clinical trials and only a handful had been approved by the FDA.
By harvesting, expanding, and injecting CD34+ cells directly to the heart muscle, this natural repair mechanism is enhanced. Early-phase clinical trials have shown the safety and efficacy of using stem cells for cardiac repair, encouraging further research and development.
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.
2/ Live Long and Prosper, Lil’ Yeasty Boys Yeast cells usually live for about one week. 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. kilobases” of DNA into a plant genome.

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.
.” This technology could be used to design protein therapeutics that can bind to, and “shut down,” harmful or misfolded proteins in living cells. Thousands of transcription factors — proteins that bind DNA and control gene expression — were studied in human cells. Nature CellBiology.
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? Nature Chemical Biology.
Bernstein is also chair of the Department of Cancer Biology at Dana-Farber Cancer Institute, a professor in cellbiology and pathology at Harvard Medical School, and holds the Richard and Nancy Lubin Family Chair. Inevitable progression Gliomas arise from glial cells, which protect and support a healthy nervous system. “So,
.” However, it isn’t clear that such a superintelligence could even be applied to its full potential in biology today, given the dearth of high-quality datasets needed to train it. Still, many of the bottlenecks slowing biology today are biophysical , rather than computational. Subscribe to Asimov Press. Even the humble E.
