miR-150 is a family of microRNA precursors found in mammals, including humans. The ~22 nucleotide mature miRNA sequence is excised from the precursor hairpin by the enzyme Dicer.[1] This sequence then associates with RISC which effects RNA interference.[2]
miR-150 functions in hematopoiesis; it regulates genes whose downstream products encourage differentiating stem cells towards becoming megakaryocytes rather than erythrocytes.[3][4] It is also thought to control B and T cell differentiation, alongside mir-155.[5][6]
Expression
The expression pattern of miR-150 varies during the differentiation of a hematopoietic stem cell lineage. Highest expression levels occur in mature, resting B and T cells but miR-150 is downregulated in their progenitor cells, including Th1 and Th2 cells.[5]
Role in cancer
miR-150 has been linked with a number of cancers including prostate cancer, in which it can be bio-accumulated and also possibly transferred from food sources.[7] It is thought to promote cancer cell proliferation in gastric cancer and has also been found to be more than 50x overexpressed in osteosarcoma.[8] The expression of miR-150 was shown to regulate levels of GAB1 and FOXP1 proteins in malignant and normal B cells, and this influences their BCR signalling [9]
Applications
miR-150 levels in blood plasma can be indicative of early sepsis; it could have a future use therapeutically in treating the condition.[10] In addition, miR-150 is one of a number of microRNAs whose expression profile could be used as a biomarker of hepatocellular carcinoma.[11]
