However, when this guardian falters due to genetic mutations, chaos ensues. Cells start to lose their identity and grow uncontrollably, giving rise to brain tumors like medulloblastoma.

SWI/SNF: The Master Regulators

Meet SWI/SNF, a complex of proteins that acts like a conductor in an orchestra. It fine-tunes the activity of genes, controlling their expression and ultimately directing cell behavior. Mutations in SWI/SNF disrupt this harmony, leading to abnormal cell growth and the formation of tumors such as ependymoma.

PIK3CA: The Fuel for Cell Growth

Imagine a car that needs fuel to run. In the case of cells, that fuel is a molecule called PI3K, and PIK3CA is the gene that produces it. When mutations occur in PIK3CA, it pumps out too much fuel, causing cells to multiply excessively and form tumors like rhabdoid sarcoma.

Genetic Mutations: The Spark that Ignites Tumor Growth

Genetic mutations are like tiny glitches in the genetic code that disrupt the normal function of genes. In the case of pediatric brain tumors, these mutations can lead to the overproduction of cell growth signals, the breakdown of protective mechanisms, and the disruption of DNA repair pathways. As a result, cells lose their ability to control their growth and division, eventually forming tumors.

Understanding the role of these genes and the mutations that affect them is crucial for developing targeted therapies and improving treatment outcomes for young patients battling pediatric brain tumors.

Clinical Entities: Unraveling the Treatment Landscape of Pediatric Brain Tumors
