My lab is focused in part on chromatin states in stem cells and cancer including heterochromatin. In fact, my lab’s website is chromatin.com. Heterochromatin is dense, often inactive chromatin. By H&E staining and electron microscopy, heterochromatin looks dark compared to the rest of the nucleus, largely composed of euchromatin. Toward the end of my postdoc […]

It’s another one of those ‘double-grant’ weekends of grant writing (on brain cancer) and reviewing, but I’m still trying to find a bit of time for some other reading. There was some important news this week including a big mess of problematic papers at Dana Farber Cancer Institute (DFCI). Recommended reads Here’s the new WaPo

It’s always exciting when your lab has a new paper and my team just published a study knocking out the H3f3a gene in mice, which codes for histone H3.3 protein. We found that loss of this gene leads to lethality at a late stage of embryonic development. There were also indications of more specific phenotypes

Happy New Year and get ready for another 364 more days of stem cell excitement and craziness in 2022. In the next day or two I’ll post my predictions for this new year. Recommended reads EO Wilson obit by Carl Zimmer in NYT. Who’s the next EO Wilson or someone like him with such big impact these

It has been fascinating in the last year to see the unfolding story of mutations in histone variant H3.3 in pediatric glioblastoma and related tumors. It seems amazing that in just over a year, a whole new area of cancer research has rapidly progressed. As I discussed in a recent post, histone H3.3 is a

A relatively newly recognized, important player in the stem cell field is a molecule called histone H3.3. Histones are key components of chromatin with integral roles in regulating almost all aspects of cell behavior through orchestrating functions such as transcription and chromosome segregation. Histone H3.3 knockout My lab has just (April 9) published new studies

Why are most brain cancers so difficult to treat leaving the unfortunate patients who suffer from them in dire circumstances so often? The short answer is that we don’t know why. This lack of understanding is like a wall standing between the cures and us for these patients. We have to climb or knockdown this

There should be more stem cell awards. Why not recognize more scientists and advocates? I used to do a Stem Cell Person of the Year Award. I have thought about bringing it back. What do you think? Scroll through some past posts on the Stem Cell Person of the Year Award. ISSCR gives out stem

When a vendor of important reagents like antibody supplier Abcam charges big money, those high Abcam prices could negatively impact research in the long run. Some of the prices are so high that buying just a few antibodies could take up a small but meaningful slice of an entire R01 grant. Sky-high Abcam prices I’ve

Some folks can view data from early, small clinical trials too skeptically or overly enthusiastically, and maybe that’s going on with some preliminary results from Verve Therapeutics. Good news? Bad news? I’m going to start with two articles about the same news that have very different vibes. What do I think? On the whole, I
