Enzymatic polymerization of phenolic compounds (catechol, resorcinol, and hydroquinone) was carried out using laccase. The mechanism of polymerization and the structures of the polymers were evaluated in terms of UV-Vis and Fourier transform infrared spectroscopy. The molecular weights of the produced polyphenols were determined with GPC. The results showed(More)
Hypoxia-inducible factor (HIF) activates the transcription of genes involved in cancer progression. Recently, HIF was reported to regulate the transcription of non-coding RNAs. Here, we show that the transcription of a long non-coding RNA (lncRNA), Gastric Adenocarcinoma Associated, Positive CD44 Regulator, Long Intergenic Non-Coding RNA (GAPLINC), is(More)
Triterpenoids from the Aglaia have been shown cytotoxicity on a broad spectrum of human tumor cells. In the present study, we extracted triterpenoids AA-5 (1) and AA-6 (2) from stems of Aglaia abbreviata, and studied their cytotoxicity in multidrug resistant (MDR) MCF-7/ADM cells. After 48 h treatment, AA-5 (1) and AA-6 (2) significantly increased(More)
