[43] [44] In a mouse model, high medulloblastoma frequency appears to be caused by the down regulation of Cxcl3, with Cxcl3 being induced by Tis21. [45] Consistently, the treatment with Cxcl3 completely prevents the growth of medulloblastoma lesions in a Shh-type mouse model of medulloblastoma. [46] Thus, CXCL3 is a target for medulloblastoma ...
The SHH gene is a member of the hedgehog gene family with five variations of DNA sequence alterations or splice variants. [37] SHH is located on chromosome seven and initiates the production of Sonic Hedgehog protein. [37] This protein sends short- and long-range signals to embryonic tissues to regulate development. [38]
SHH medulloblastoma: the most common form in patients under 5 years old. It also occurs in children over 17 and makes up about 30% of all medulloblastoma cases.
RU-SKI 43 inhibits the activity of SHHat, an enzyme that catalyzes the palmitoylation of Shh. [56] Since palmitoylation is essential for the activity of Shh, [57] inhibition of SHHat by RU-SKI 43 inhibits Shh signaling in cancer cells. [58] [59] 5E1, a monoclonal antibody against Shh, has been shown to inhibit medulloblastoma growth in mouse ...
Isabella Strahan, 19, said she started experiencing headaches, which prompted her to seek medical attention.
Holoprosencephaly, the failure of the embryonic prosencephalon to divide to form cerebral hemispheres, occurs with a frequency of about 1 in 8,000 live births and about 1 in 200 spontaneous abortions in humans and is commonly linked to mutations in genes involved in the hedgehog pathway, including SHH and PTCH.

Silmitasertib is in clinical trials for use as an adjunct to chemotherapy in the treatment of cholangiocarcinoma (bile duct cancer), [1] is in phase I and II clinical trials for the treatment of recurrent Sonic Hedgehog (SHH) medulloblastoma, [2] [3] and in preclinical development for other cancers, including hematological and lymphoid ...
In fact, the transcription of CXCL3 is directly regulated by BTG2, and CXCL3 is able to induce cell-autonomously the migration of cerebellar granule precursors. Treatment with CXCL3 prevents the growth of medulloblastoma lesions in a Shh-type mouse model of medulloblastoma. [34] Thus, CXCL3 is a target for medulloblastoma therapy. [33] [34]
