circRNA-disease information
Detected method:
Q
Detected method confidence High
Expression pattern:
UP
Associated gene: -
Associated microRNA: hsa-miR-145
Biological function: CircRNA_0044556 regulates the viability of ADM-treated MDA-MB-231 and MDA-MB-231/ADM cells,CircRNA_0044556 affects the apoptotic and migratory capacities of TNBC cells with or without ADM treatment
Molecular mechanism: CircRNA_0044556 sponges hsa-miR-145, which is expressed at a low level in TNBC tissues and TNBC cells with or without ADM treatment, Overexpressed circRNA_0044556 attenuates apoptosis and enhances migration of TNBC cells with or without ADM treatment by targeting hsa-miR-145, hsa-miR-145 targets NRAS, which is overexpressed in TNBC tissues and cells with or without ADM treatment
Survival: -
Supported No.:
1
Description:

CircRNA_0044556 was negatively correlated with miR_145 yet positively correlated with NRAS, the target gene of miR_145, in addition to the discovery suggesting the negative regulatory effects of circRNA_0044556 on miR_145. CircRNA_0044556 diminished the sensitivity of TNBC cells to ADM via the miR_145/NRAS axis.
