miRNAs as one of the potential therapeutic agents have been recently considered for cancer treatment. AS1411 (aptNCL) is a DNA aptamer specifically binding to nucleolin protein on the cancer cell surface with antiproliferative effect. The aim of the study was to develop a conjugate consisted of aptNCL (as targeted delivery of therapeutic agent) and miRNA let-7d (as a tumor suppressor) using two...

Hepatitis B virus X (HBx) protein has been known to play an important role in development of hepatocellular carcinoma (HCC). The aim of this study is to find out whether HBx protein expression affects antiproliferative effect of an epidermal growth factor receptor-tyrosine kinase (EGFR-TK) inhibitor and a MEK inhibitor in HepG2 and Huh-7 cell lines. We established HepG2 and Huh-7 cells transfec...

The oxysterol receptors [liver X receptors (LXRalpha and LXRbeta)] regulate cholesterol and lipid biosynthesis and several studies link dysregulation of these metabolic pathways to aberrant cell growth. Here, we show that activation of LXR significantly reduced proliferation in several human breast cancer cells lines. LXR suppressed messenger RNA and/or protein expression of Skp2, cyclin A2, cy...

in our search for new anticancer medicinal plants, the antiproliferative activity of the methanol extract of daphne mucronata (thymelaeaceae) was evaluated using human myelogenous leukemia k562 cells. the cells responded to plant treatments in a dose dependent manner and the ic50 of the crude extract (equivalent to 1 g of plant leaves powder per ml) and the purified active component were found ...

Enzymatic hydrolysates of different food proteins demonstrate health benefits. Search for diet related food protein hydrolysates is therefore of interest within the scope of functional foods. Mungbean is one of the popular foods in India because of rich protein source. In this study, mungbean vicilin protein (MBVP) was enzymatically hydrolysed by alcalase and trypsin under optimal conditions. W...

Three novel 19-nor-1α,25-dihydroxyvitamin D3 derivatives modified at C1 and/or C3 with an amino group were synthesized to study the influence of substitution one or both hydroxyl groups A-ring by on affinity for vitamin D receptor (VDR) and binding protein (hDBP), also antiproliferative activity. The precursors prepared from cis,cis-1,3,5-cyclohexanetriol applying a desymmetrization reaction pr...

Our previous report (Muir, D., S. Varon, and M. Manthorpe. 1990. J. Cell Biol. 109:2663-2672) described the isolation and partial characterization of a 55-kD antiproliferative protein found in Schwann cell (SC) and schwannoma cell line-conditioned media and we concluded that SC proliferation is under negative autocrine control. In the present study the 55-kD protein was found to possess metallo...

A number of proteins post-translationally modified by the covalent attachment of mevalonate-derived isoprene groups farnesol (FOH) or geranylgeraniol (GGOH), play a role in cell proliferation. For this reason, protein farnesyltransferase (PFTase) and protein geranylgeranyltransferases (PGGTases) I and II have gained attention as novel targets for the development of antiproliferative agents. Mon...

Dermaseptin-B2 (DRS-B2) is a multifunctional cationic antimicrobial peptide (CAP) isolated from frog skin secretion. We previously reported that DRS-B2 possesses anticancer and antiangiogenic activities in vitro and in vivo. In the present study, we evaluated the antiproliferative activity of DRS-B2 on numerous tumor cell lines, its cell internalization and studies of its molecular partners as ...
