Description:

the up-regulated miRNAs (miR-93 and miR-130b) target the 3' untranslated region (3'UTR) of the mRNA for a tumor suppressor protein, tumor protein 53-induced nuclear protein 1 (TP53INP1). A low expression level of TP53INP1 protein was found in HTLV-1-transformed cells. Additionally, when antagomirs were used to knock down miR-93 and miR-130b in these cells, the expression of TP53INP1 was increased, suggesting that the latter is regulated inside cells by the former. A role for TP53INP1 in regulating cell growth was established by experiments that showed that enhanced TP53INP1 expression increased apoptosis. Collectively, the findings implicate a miR-93/miR-130b-TP53INP1 axis that affects the proliferation and survival of HTLV-1-infected/transformed cells.
