histone H3.3

3 min read

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 fascinating molecule that plays critical roles in regulating cellular chromatin and epigenomic states. H3.3 is, as mentioned above, also frequently mutated in some of the worst childhood brain tumors. …Read More

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 on histone H3.3, the first of their kind on the endogenous histone H3.3 protein in mammals. The work was supported by CIRM and NIH. Much of our work was …Read More

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 wall. Brain cancers are a diverse group, but lessons about one or more types can sometimes teach us about others. There may also be patterns that transcend different types …Read More
