Medulloblastoma is the most common malignant brain tumor of childhood. It is currently stratified into four molecular variants through the advances in transcriptional profiling. They include: wingless, sonic hedgehog (SHH), Group III, and Group IV. The SHH group is characterized by constitutive activation of the SHH signaling pathway, and genetically characterized by mutations in patched homolog 1 (PTCH1) or other downstream pathway mutations. SHH inhibitors have become of great clinical interest in treating SHH-driven medulloblastoma. Many inhibitors are currently in different stages of development, some already approved for other SHH-driven cancers, such as basal cell carcinoma. In vitro and in vivo medulloblastoma studies have shown efficacy and these findings have been translated into Phase I and II clinical trials. In this review, we present an overview of SHH medulloblastoma, as well as a discussion of currently available SHH inhibitors, and the challenges associated with their use.
This research output has an Altmetric Attention Score of 1. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 05 April 2017.
All research outputs
#15,452,475
of 22,962,258 outputs
Outputs from Expert Review of Neurotherapeutics
#865
of 1,192 outputs
Outputs of similar age
#157,724
of 267,830 outputs
Outputs of similar age from Expert Review of Neurotherapeutics
#16
of 21 outputs
Altmetric has tracked 22,962,258 research outputs across all sources so far. This one is in the 22nd percentile – i.e., 22% of other outputs scored the same or lower than it.
So far Altmetric has tracked 1,192 research outputs from this source. They typically receive more attention than average, with a mean Attention Score of 7.6. This one is in the 20th percentile – i.e., 20% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 267,830 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 32nd percentile – i.e., 32% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 21 others from the same source and published within six weeks on either side of this one. This one is in the 23rd percentile – i.e., 23% of its contemporaries scored the same or lower than it.
