Evidence Type(s): Oncogenic
Summary:
Mutation: S703I | Summary: The JAK1S703I mutation is identified as an activating mutation contributing to tumor development in HCC patients. It is associated with elevated expression levels of phosphorylated JAK1 and STAT proteins, suggesting its role in tumor progression. The mutation is capable of continual proliferation in the absence of IL-3 and is present in a patient-derived xenograft (PDX) model, indicating its critical role in tumorigenesis. Additionally, it activates the JAK-STAT signaling pathway, driving cell proliferation in vitro.
Evidence Type: Oncogenic
Mutation: A1086S | Summary: The A1086S mutation is located in the catalytic kinase domain of JAK1, suggesting its role in tumor development.
Evidence Type: Oncogenic
Mutation: N451S | Summary: The N451S mutation is found in the SH2 domain of JAK1, indicating its potential contribution to tumor progression.
Evidence Type: Oncogenic
Mutation: E483D | Summary: The E483D mutation, located in the SH2 domain of JAK1, may play a role in tumor development. It is part of a study exploring biological functions in the JAK-STAT signaling pathway, indicating its potential role in tumor development.
Evidence Type: Oncogenic
Mutation: S729C | Summary: The JAK1S729C mutation is described as a known and recurrent activating mutation, indicating its role in tumor development. It serves as a positive control in studies, suggesting it contributes to continual proliferation and tumor progression.
