Detail of retinoblastoma (RB)
ncRNA name hsa-let-7b
ncRNA Category miRNA
Disease name retinoblastoma (RB)
Species Homo sapiens
Tissues/Cell_line RB samples; RB cell line Y79 and WERI-RB1; breast cancer cell lines MDA-MB-453 and MCF-7; human retinal Müller glial cell line MIO-M1; human thyroid follicular epithelial cell line Nthy-ori 3-1
Methods qRT-PCR, luciferase reporter assay, MTT assay, Western blot, immunofluorscence
Expression pattern down-regulated
Functional description let-7b showed consistent down regulation in both the retinoblastoma cell lines when compared to other let-7 family members and showed high up-regulation in Nthy-ori 3-1. Our results showed that the EGP2-promoter HSV-TK (EGP2-TK) construct with 2 or 4 copies of let-7b miRNA targets expressed TK gene only in Y79, WERI-Rb-1, while the TK gene did not express in MIO-M1.
