New Delhi, Jan 17 (NationPress) A group of researchers from Australia has explored an innovative method to combat childhood brain cancer by combining two medications in laboratory studies.
This research, featured in the journal Science Translational Medicine, indicates that the synergistic use of these two therapies may yield more effective results than applying each one individually.
The team, affiliated with the Children's Cancer Institute and the University of New South Wales, examined this combined therapeutic strategy on challenging brain tumors known as diffuse midline gliomas (DMG) within the lab.
This category includes the diffuse intrinsic pontine glioma (DIPG), a rare and lethal childhood brain cancer that falls under the DMG classification. Typically, children diagnosed with DIPG have a survival period of around 12 months.
According to Conjoint Associate Professor Maria Tsoli from UNSW, "We understand that no singular drug treatment can eliminate the most aggressive brain cancers by itself."
This insight prompted the researchers to investigate whether a combination of treatments could offer enhanced efficacy.
UNSW Conjoint Professor David Ziegler pointed out that a significant hurdle with these tumors is that numerous genes become activated simultaneously, facilitating the cancer's progression.
"Identifying a method to deactivate all these genes has been extremely challenging," he stated.
The study revealed that DMG cells proliferate uncontrollably due to alterations that disrupt normal gene function.
The researchers identified a promising drug combination that effectively halts the transcription process, thereby deactivating thousands of genes simultaneously.
The focus was on two critical proteins involved in transcription: FACT and BET, which are present at elevated levels in cancer cells. Although existing drugs that inhibit these proteins do exist, their singular application only marginally slows down the cancer's advancement.
However, when these drugs were utilized together, laboratory experiments indicated that the cancer cells perished.
Mouse trials demonstrated that this combination not only inhibited tumor growth but also extended the lifespan of the mice.
The research team also noted that this treatment activated immune system-related signals, suggesting that the cancer cells might become more recognizable and targetable by the body's immune response.
Consequently, the researchers believe that incorporating an immune-focused treatment, like CAR T-cell therapy, could enhance the results in future studies.
Both drug types are currently being developed for patient use and are now undergoing clinical trials.
Point of View
The potential of this study is significant. It emphasizes the urgency of innovation in treating childhood brain cancers, where current options remain limited. The focus on combination therapies represents a pivotal shift in our understanding and approach to these aggressive tumors. It’s crucial that we support ongoing research in this area, as it holds promise for improved outcomes for vulnerable patients.

The researchers focused on diffuse midline gliomas (DMG), particularly the diffuse intrinsic pontine glioma (DIPG), which is known to be aggressive and challenging to treat.
How does the combination therapy work?
The combination therapy targets key proteins involved in gene transcription, effectively shutting down thousands of genes associated with cancer growth.
Are these drugs available for clinical use?
Yes, both types of drugs used in the study are currently being developed and are in clinical trials for patient use.
What future treatments may enhance this approach?
The researchers suggest that integrating immune-based treatments, such as CAR T-cell therapy, could further improve the effectiveness of this combined drug approach.
