Discovery: Cell protein transport and an approach to cancer
The center of this story, in more ways than one, is the Golgi apparatus (pronounced ‘goal jee’). As a crude analogy, think of the Golgi apparatus as a re-packaging operation inside of living cells. It...

“You can think of it this way,” said Ren. “Neurons and skin cells share the identical set of genetic material – DNA – yet their structure and function are very different. The difference can be...
View ArticleNew for epigenetics: Active pseudogenes and RNA as gene regulator
How is it that the human genome, with about 23,000 protein coding genes, can produce such a complicated organism as the human being, when the laboratory flatworm (C. elegans, a relatively simple...
View ArticleStem cells: Myc does much more
To put it mildly, not thinking beyond assumptions can lead to surprises. This also applies to science. For many years scientists thought that the gene known as Myc (“mick”) plays a role in causing...
View ArticleNew tool: Nanoneedle to the nucleus
For scientists, as for everybody else, it helps to see what’s happening. This is hard to do in the nucleus of a living cell. Standard techniques for watching the activity within the nucleus use dyes or...

DNA winds around histones….Credit: Max Planck Society Most everybody knows that DNA is the carrier of the genetic code, the instructions for how life reproduces, grows, and maintains. Cell biologists...
View ArticleDiscovery: An immune system within cells
The human body has a pretty good immune system. Because it’s so crucial to our health, scientists and doctors have been studying the immune system intensely for a long time. A good deal is known about...
