General description

Diffuse intrinsic pontine gliomas (DIPG) are highly aggressive and difficult to treat tumors arising in the ventral pons of the brain stem. Despite therapeutic advances, DIPG is incurable and most patients, primarily children, die within 2 years of diagnosis. DIPG is one of the leading causes of death in children with brain tumors .

A somatic mutation of histone H3.3 resulting in a lysine 27 to methionine substitution (H3.3K27M) occurs in 60% of DIPG . In H3.3K27M DIPG patient samples, levels of H3K27 dimethylation (H3K27me2) and trimethylation (H3K27me3) are reduced globally. Expression of H3.3K27M was also shown to be associated with increased levels of H3K27 acetylation (H3K27ac) and recruitment of bromodomain proteins at sites of active transcription . These epigenetic changes are thought to be important factors driving DIPG oncogenesis
SF7761 is a human glioma cell line derived by surgical biopsy from a young female H3.3K27M DIPG patient (5). The tumor cells were immortalized with hTERT (human telomerase ribonucleoprotein reverse transcriptase) using retroviral transduction. SF7761 cells are tumorigenic in athymic rodents with the tumor cells recapitulating the infiltrative growth of human brainstem gliomas (5, 6).

IMPORTANT NOTE: SF7761 are grown as neurospheres in suspension culture. Neurospheres are to be passaged using gentle mechanical trituration when they reach diameters of 200-500 um or through enzymatic dissociation.

Recent studies have identified a Lys 27-to-methionine (K27M) mutation at one allele of H3F3A, one of the two genes encoding histone H3 variant H3.3, in 60% of high-grade pediatric glioma cases. The median survival of this group of patients after

Diffuse intrinsic pontine gliomas arise almost exclusively in children, and despite advances in treatment, the majority of patients die within 2 years after initial diagnosis. Because of their infiltrative nature and anatomic location in an eloquent area of the brain

Sequencing of pediatric gliomas has identified missense mutations Lys27Met (K27M) and Gly34Arg/Val (G34R/V) in genes encoding histone H3.3 (H3F3A) and H3.1 (HIST3H1B). We report that human diffuse intrinsic pontine gliomas (DIPGs) containing the K27M mutation display significantly lower overall amounts
