2-(4-Amino-3-methylphenyl)benzothiazole (DF 203, NSC 674495) is a candidate antitumor agent with potent and selective activity against human-derived tumor cell lines in vitro and in vivo. Only sensitive cell lines (e.g., MCF-7) were able to accumulate and metabolize DF 203, forming the main inactive metabolite, 2-(4-amino-3-methylphenyl)-6-hydroxybenzothiazole (6-OH 203). Selective metabolism m...

The present study investigated the relationship between microRNA-203 (miR-203) and the p53 upregulated modulator of apoptosis (Puma) in colon (HCT116) and lung cancer (A549) cells. Colon and lung cancer cell lines were selected for this study since a relationship between p53/miR-203 and p53/Puma has been established in both cancers. In the present study, adriamycin and nutlin-3 were used to act...

BACKGROUND/AIMS MicroRNA (miRNA) plays important roles in the development of different cancers. In this study, we investigated the roles and mechanisms of miR-203 in human cervical cancer. METHODS miR-203 expression was detected in cervical cancer tumors and cell lines by qRT-PCR. The methylation status in the promoter region of miR-203 was examined by methylation-specific PCR. The functional...

In lab-scale experiments at the 2-stage activated sludge pilot plant of Vienna’s central WWTP it is shown that the wastewater soluble COD concentration, which is inert to a sludge with SRT < 1 d (SIA) is about double compared to the SI concentration in sludge with SRT > 10 d (SIB). Unexpectedly the ratio of SIA/SIB is independent of the sludge age between SRTs of 0.4 and 1.0 days. The differenc...

MicroRNA (miR)-203 has been demonstrated to function as a suppressor in tumorigenesis. Recently, miR-203 was reported to play a role in malignant melanoma (MM); however, the detailed function of miR-203 in MM remains unclear. In the present study, the expression of miR-203 was shown to be significantly downregulated in MM tissues when compared with normal adjacent tissues. Based on a bioinforma...

miRNA-203 is involved in the development and progression of various types of cancer. However, its role in cervical cancer remains unclear. The aim of this study was to investigate the effect of miRNA-203 on the proliferation and migration of HeLa cervical cancer cells, as well as survivin expression in these cells. A miRNA-203 primer probe was designed according to a sequence obtained from NCBI...
