abstract

retinoblastoma is the most common intraocular tumor in children resulting from genetic alterations and transformation of mature retinal cells. the objective of this study was to investigate the effects of sd-208, tgf-β-ri kinase inhibitor, on the expression of some mirnas including a mir-17/92 cluster in retinoblastoma cells. prior to initiate this work, the cell proliferation was studied by methyl thiazolyl tetrazolium (mtt) and bromo-2′-deoxyuridine (brdu) assays. then, the expression patterns of four mirnas (18a, 20a, 22, and 34a) were investigated in the treated sd-208 (0.0, 1, 2 and 3 µm) and untreated y-79 cells. a remarkable inhibition of the cell proliferation was found in y-79 cells treated with sd-208 versus untreated cells. also, the expression changes were observed in mirnas 18a, 20a, 22 and 34a in response to sd-208 treatment ( p <0.05). the findings of the present study suggest that the anti-cancer effect of sd-208 may be exerted due to the regulation of specific mirnas, at least in this particular retinoblastoma cell line. to the best of the researchers’ knowledge, this is the first report demonstrating that the sd-208 could alter the expression of tumor suppressive mirnas as well as oncomirs in vitro. in conclusion, the present data suggest that sd-208 could be an alternative agent in retinoblastoma treatment.

Down-regulation of miR-135b in colon adenocarcinoma induced by a TGF-β receptor I kinase inhibitor (SD-208)

  Objective(s):Transforming growth factor-β(TGF-β) is involved in colorectal cancer (CRC). The SD-208 acts as an anti-cancer agent in different malignancies via TGF-β signaling. This work aims to show the effect of manipulation of TGF-β signaling on some miRNAs implicated in CRC. Materials and Methods: We investigated the effects of SD-208 on SW-48, a colon adenocarcinoma cell line. The cell li...

2-Hydroxypropyl-β-Cyclodextrin Acts as a Novel Anticancer Agent

2-Hydroxypropyl-β-cyclodextrin (HP-β-CyD) is a cyclic oligosaccharide that is widely used as an enabling excipient in pharmaceutical formulations, but also as a cholesterol modifier. HP-β-CyD has recently been approved for the treatment of Niemann-Pick Type C disease, a lysosomal lipid storage disorder, and is used in clinical practice. Since cholesterol accumulation and/or dysregulated cholest...
