SHIP1 is targeted by miR-155 in acute myeloid leukemia.
The SH2 domain-containing inositol 5'-phosphatase 1 (SHIP1) has been implicated as a suppressor of hematopoietic transformation as its activity can inhibit the PI3K/Akt signaling pathway. Reduced activity of SHIP1 has been observed in acute myeloid leukemia (AML). SHIP1 is a target of microRNA-155 (miR-155). Therefore, the aim of the present study was to investigate the role of miR-155/SHIP1 in...
متن کاملInositol phosphatase SHIP1 is a primary target of miR-155.
MicroRNA-155 (miR-155) has emerged as a critical regulator of immune cell development, function, and disease. However, the mechanistic basis for its impact on the hematopoietic system remains largely unresolved. Because miRNAs function by repressing specific mRNAs through direct 3'UTR interactions, we have searched for targets of miR-155 implicated in the regulation of hematopoiesis. In the pre...
متن کاملB and T Lymphocyte Attenuator is a Target of miR-155 during Naive CD4+ T Cell Activation
Background: MicroRNA-155 (miR-155) is upregulated during T cell activation, but the exact mechanisms by which it influences CD4+ T cell activation remain unclear. Objective: To examine whether the B and T lymphocyte attenuator (BTLA) is a target of miR-155 during naïve CD4+ T cell activation. Methods: Firefly luciferase reporter plasmids pEZX-MT01-wild-type-BTLA and pEZX-MT01-mutant-BTLA were ...
متن کاملOnco-miR-155 targets SHIP1 to promote TNFα-dependent growth of B cell lymphomas
Non-coding microRNAs (miRs) are a vital component of post-transcriptional modulation of protein expression and, like coding mRNAs harbour oncogenic properties. However, the mechanisms governing miR expression and the identity of the affected transcripts remain poorly understood. Here we identify the inositol phosphatase SHIP1 as a bonafide target of the oncogenic miR-155. We demonstrate that in...
متن کاملMiR-21 and MiR-155 promote non-small cell lung cancer progression by downregulating SOCS1, SOCS6, and PTEN
Lung cancer remains the leading cause of cancer-associated death worldwide. MiR-21 and miR-155 are the most amplified miRNAs in non-small cell lung carcinoma (NSCLC), and are critical promoters of NSCLC progression. However, it remains unclear how miR-21 and miR-155 induce cancer progression, and whether these miRNAs share common targets, such as tumor suppressor genes required to prevent NSCLC...
