Ho-ho-ho! Gather ’round, my curious elves, for a tale of a not-so-jolly challenge in the land of medical mysteries. We’re delving into the frosty realm of Glioblastoma multiforme (GBM), a most unwelcome visitor in the brains of those it afflicts, much like a lump of coal in a Christmas stocking. This crafty culprit, originating from the star-like astrocytes, is as stubborn as a reindeer who won’t budge, making up about 30% of those pesky central nervous system malignancies.

Now, despite the best efforts of the medical workshop—armed with their surgical tools, chemo concoctions, and radiopharmaceutical goodies—the prognosis for those facing GBM is as bleak as a blizzard in July. This GBM is a real Scrooge, you see, and it’s high time we found a way to curb its bah-humbug ways.

Enter the Notch signaling pathway, a series of molecular rooftop chimneys that, when working properly, keep the cellular festivities balanced. But in GBM, this pathway is more tangled than Christmas lights, leading to a raucous overexpression of genes like MYC, Hes1, and Hey1, which in turn, encourage cells to proliferate and differentiate with reckless abandon.

Recent scrolls of research, possibly from the top shelf of Santa’s library, have shed light on the role of non-coding RNAs (ncRNAs)—the silent night messengers of the cellular world. These ncRNAs, including the lengthy long non-coding RNAs (lncRNAs) and the tiny microRNAs (miRNAs), are like the elves of gene regulation, controlling the Notch signaling pathway’s naughty or nice list by targeting critical mRNA expression.

What’s more, these ncRNAs could be the shiny new ornaments on the GBM prognosis tree, serving as markers to predict and understand the course of this grinchy disease. This review, my dear friends, is a sleigh ride through the latest studies that explore how these ncRNAs regulate the Notch signaling pathway in the context of GBM. So, let’s jingle all the way through the science and hope it leads us to new ways to keep GBM at bay!
