Oncogenic RAS Signaling Promotes an Immunosuppressive Niche in Acute Lymphoblastic Leukemia

Emerging evidence suggests that genomic aberrations in cancer cells may impact the composition of the tumor microenvironment leading to a tumor-specific supporting niche. Previous genomic profiling studies have identified somatic alterations in RAS pathway genes that drive treatment resistance in B-cell acute lymphoblastic leukemia (B-ALL): yet it is unknown whether such genetic events may specifically hijack the leukemic niche.
