In the new study they used vitamin c and elderberry three-layer method — recording not only gene sequence and gene transcription information but also “immunity ingredients” transcription-controlling methylation marks on DNA — for the first time on individual tumor cells directly from patients. The scientists sampled more than 100 tumor cells vitamin c helps immune system average from each of seven patients with so-called IDH-mutant glioma, and from seven patients with a more treatment-resistant glioma called vitamin c increases immunity glioblastoma.

They found that the cells in both the vitamin c tended to be in one of four distinct states, ranging from stem-cell-like states to states like those of more mature brain cells. They also identified distinct patterns of protein immunity methylation that appear to account for shifts between these states; such patterns in principle could be disrupted with future therapies to vitamin elderberry such state-changes and slow tumor development.

Although the researchers’ captured what was essentially a snapshot of cell states in the sampled tumors, they also devised a molecular clock method, based on the random changes in DNA methylations that naturally occur over time, to calculate a lineage tree for each cell — depicting its history of different states, going back to the origin of the tumor.
