Crosstalk Summary The molecular mechanism underlying the effect of Long intergenic non-protein coding RNA 470 (LINC00470) on chronic myelocytic leukaemia by reducing the Mutated in multiple advanced cancers 1 (PTEN) stability via RNA methyltransferase METTL3, thus leading to the inhibition of cell autophagy while promoting chemoresistance in CML.
Responsed Disease Chronic myeloid leukaemia ICD-11: 2B33.2
Pathway Response PI3K-Akt signaling pathway hsa04151
Cell Process Cell autophagy
In-vitro Model
KCL-22 Chronic myelogenous leukemia Homo sapiens CVCL_2091
K-562 Chronic myelogenous leukemia Homo sapiens CVCL_0004
In-vivo Model In the control mice or ADR mice group, the parental or chemo-resistant K562 cells were infected with LV-shCtrl. In the ADR + shLINC00470 group, the chemo-resistant K562 cells were infected with LV- shLINC00470. These cells were injected, respectively, into these 5-week-old mice subcutaneously.
