Epigenetic Manipulations Can Accelerate or Reverse Aging in Mice
Alejandra Manjarrez, PhD | Jan 12, 2023 | 4 min read
Repairing damaged DNA appears to drive aging by causing the loss of epigenetic information, but restoring that information reverses such effects, a study finds.

With few resources and hesitant investors, basic scientists must rely on clinicians, patient advocates, and their own keen eye for biological connections.
Drug Makers on the Apoptotic Trail
Ted Agres | Jun 24, 2001 | 4 min read
Apoptosis, a key process in the development of embryonic tissue differentiation, later helps to regulate the normal cellular life cycle by destroying damaged cells. When something goes awry, too little apoptosis can make cancer cells resistant to chemotherapy and even death-defiant. At the other extreme, premature or excessive apoptosis has been linked to neurodegenerative diseases, such as Alzheimer's, and to nerve cell loss in strokes. Not surprisingly, many major pharmaceutical companies rec
How Cells Find Their Way

Organisms need to sense their environment. By sensing, they can develop, heal wounds, protect against invaders, and create blood vessels. Chemotaxis, or directional sensing, allows cells to detect chemicals with exquisite sensitivity. Some chemotactic cells can sense chemical gradients that differ by only a few percent from a cell's front to its back. Although discovery of the molecule types involved in chemotaxis, as with other kinds of cell signaling events, has mounted, the details of how thi
Comparative Genomics Reveals The Interrelatedness Of Life

Photo: Karen Young Kreeger EXCITING ERA: TIGR's Craig Venter says efforts to unravel the information being gathered will last "into the next century." While the list of genome projects grows, research focus is shifting from structure to function. So even as automated DNA sequencers crank out bases and powerful software overlaps pieces of genomes (contigs) to establish gene orders, investigators are searching and comparing those sequences among species, an approach called comparative genomics.
Enter the Matrix

WHAT A TANGLED WEB:Courtesy of Philip B. MessersmithFibroblasts are cellular workhorses of extracellular matrix production, spinning out the majority of collagens, the most abundant proteins in the animal kingdom.Appreciation in biology can come slowly. Researchers once deemed as junk the parts of genes not represented in proteins; likewise, neuroglia were thought to be mere bystanders to neurons. So it is with the extracellular matrix (ECM), the "scaffolding" and "glue" that fill the spaces amo
Dedifferentiation: More Than Reversing Fate
Ricki Lewis | Aug 29, 2004 | 5 min read
Courtesy of Cecil Fox and the National Cancer InstituteDifferentiation, the stepwise specialization of cells, and transdifferentiation, the apparent switching of one cell type into another, capture much of the stem cell spotlight. But dedifferentiation, the developmental reversal of a cell before it reinvents itself, is an important process, too. This loss of specialization is believed to factor heavily into stem-cell culture techniques and pathological conditions such as cancer. Determining its

For many laboratories, monkey business is no laughing matter. The rise in bioterrorism research after the Sept. 11 tragedy puts an increased demand on the already limited supply of rhesus monkeys for research ("Monkey deficit crimps laboratories as scientists scramble for alternatives," The Wall Street Journal, May 14, 2002). The genetic similarity between humans and rhesus monkeys has helped establish the species as the preferred nonhuman primate model for medical research, making the monkeys e
