<P><B>Background</B></P><P>Smad3 linker phosphorylation plays essential roles in tumor progression and metastasis. We have previously reported that the mutation of Smad3 linker phosphorylation sites (Smad3-Erk/Pro-directed kinase site mutant constructs [EPSM]) markedly reduced the tumor progression while increasing the lung metastasis in breast cancer.</P><P><B>Methods</B></P><P>We performed high-throughput RNA-Sequencing of the human prostate cancer cell lines infected with adenoviral Smad3-EPSM to identify the genes regulated by Smad3-EPSM.</P><P><B>Results</B></P><P>In this study, we identified genes which are differentially regulated in the presence of Smad3-EPSM. We first confirmed that Smad3-EPSM strongly enhanced a capability of cell motility and invasiveness as well as the expression of epithelial-mesenchymal transition marker genes, <I>CDH2</I>, <I>SNAI1</I>, and <I>ZEB1</I> in response to TGF-β1 in human pancreatic and prostate cancer cell lines. We identified <I>GADD45B</I>, <I>CTGF</I>, and <I>JUNB</I> genes in the expression profiles associated with cell motility and invasiveness induced by the Smad3-EPSM.</P><P><B>Conclusions</B></P><P>These results suggested that inhibition of Smad3 linker phosphorylation may enhance cell motility and invasiveness by inducing expression of <I>GADD45B</I>, <I>CTGF</I>, and <I>JUNB</I> genes in various cancers.</P>

<P>Significant enhancement of solution-processed CuInxGa1-x(Se,S)(2) (CIGSSe) thin-film solar cell performance was achieved by inducing a band gap gradient in the film thickness, which was triggered by the chalcogenization process. Specifically, after the preparation of an amorphous mixed oxide film of Cu, In, and Ga by a simple paste coating method chalcogenization under Se vapor, along with the flow of dilute H2S gas, resulted in the formation of CIGSSe films with graded composition distribution: S-rich top, In- and Se-rich middle, and Ga- and S-rich bottom. This uneven compositional distribution was confirmed to lead to a band gap gradient in the film, which may also be responsible for enhancement in the open circuit voltage and reduction in photocurrent loss, thus increasing the overall efficiency. The highest power conversion efficiency of 11.7% was achieved with J(sc) of 28.3 mA/cm(2), V-oc of 601 mV, and FF of 68.6%.</P>

The anti-melanogenic effects of the extract of Angelica tenuissima (AT) root and the extract of AT root fermented by Aspergillus oryzae (FAT) were investigated. These effects were determined by measuring the inhibitory activity of AT and FAT on melanin production in B16F10 melanocytes and with in vitro tyrosinase activity assays. The AT extract inhibited melanin production at concentrations above 250 μg/ml, and this inhibitory effect was significantly enhanced by the fermentation process with A. oryzae. HPLC analysis resulted in the isolation of two active compounds from both the AT and FAT extracts. Their chemical structures were identified as decursin and Z-ligustilide through comparison with previously reported NMR data. The decursin and Z-ligustilide contents were increased in the FAT extract and could be responsible for its enhanced inhibitory effects on melanin production and tyrosinase activity compared with that of the AT extract.
