SRY-related HMG-box gene 11 (SOX11) is a transcription factor overexpressed in mantle cell lymphoma (MCL), a subset of Burkitt lymphomas (BL) and precursor lymphoid cell neoplasms but is absent in normal B-cells and other B-cell lymphomas. SOX11 has an oncogenic role in MCL but its contribution to BL pathogenesis remains uncertain. Here, we observe...

Mantle cell lymphoma (MCL) is an incurable B-cell neoplasm characterized by an aggressive behavior, short responses to conventional therapies and SOX11 overexpression, which is associated with aggressive disease features and inferior clinical outcome of patients. Oxidative stress is known to induce tumorigenesis and tumor progression, whereas high...

The sterile alpha motif and histidine-aspartate (HD) domain containing protein 1 (SAMHD1) is a deoxynucleoside triphosphate triphosphohydrolase with ara-CTPase activity that confers cytarabine (ara-C) resistance in several haematological malignancies. Targeting SAMHD1's ara-CTPase activity has recently been demonstrated to enhance ara-C efficacy in...

Mantle cell lymphoma (MCL) is an incurable B-cell neoplasm characterized by its aggressive behavior, short responses to conventional therapies and SOX11 overexpression. Oxidative stress is known to induce tumorigenesis and tumor progression, whereas high levels of antioxidant genes have been associated with chemoresistance in different cancers. How...

SOX11 overexpression has been associated with aggressive behavior of mantle cell lymphomas (MCL). SOX11 is overexpressed in embryonic and cancer stem cells (CSC) of some tumors. Although CSC have been isolated from primary MCL, their relationship to SOX11 expression and contribution to MCL pathogenesis and clinical evolution remain unknown. Here, w...

Mantle cell lymphoma (MCL) is a mature B cell neoplasm with two distinct biological subtypes regarding clinical, molecular and pathological features. Conventional MCL (cMCL) subtype is characterized by high aggressiveness and poor outcome with frequent relapses after initial response to treatment, suggesting the presence of a population of cancer s...

Mantle cell lymphoma (MCL) is a mature B-cell neoplasm with a heterogeneous clinical and biological behavior. SOX11 oncogenic expression contributes to the aggressiveness of these tumors by different mechanisms including tumor and stromal cell interactions. However, the precise composition of the immune cell microenvironment of MCL, its possible re...

USP25 deubiquitinating enzyme is a key member of the ubiquitin system, which acts as a positive regulator of the Wnt/β-catenin signaling by promoting the deubiquitination and stabilization of tankyrases. USP25 is characterized by the presence of a long insertion in the middle of the conserved catalytic domain. The crystal structure of USP25 display...

Key Points SOX11 regulates MCL homing and invasion via direct regulation of CXCR4 and FAK expression and PI3K/AKT and ERK1/2 signaling activation. SOX11 expression increases CAM-DR, contributing to a more aggressive MCL phenotype.
