NUDT21 knockdown inhibits proliferation and promotes apoptosis of pancreatic ductal adenocarcinoma through EIF2 signaling.

The NUDT family is thought to play an important role in cancer growth and progression. However, the clinicopathologic significance and potential role of nucleotide diphosphate-linked X-component motif 21, NM_007006 (NUDT21) in pancreatic ductal adenocarcinoma (PDAC) remains largely unknown. In this study, we observed that NUDT21 was frequently up-expressed in PDAC.

Antisense RhoC gene suppresses proliferation and invasion capacity of human QBC939 cholangiocarcinoma cells.

Background: Cholangiocarcinoma is a highly aggressive, fatal malignancy, which is resistant to all current therapeutic approaches. The recent elevation in the incidence of cholangiocarcinoma has highlighted the need for novel approaches targeting the molecular basis of its invasiveness. Previously we reconstructed a RhoC antisense eukaryotic expression vector and transfected it into a cholangiocarcinoma cell line (QBC939) by the lipofectamine method.

Electrochemical reduction of nitrobenzene at carbon nanotube electrode.

The electrochemical behaviors of nitrobenzene at a pyrolytic graphite electrode modified with carbon nanotubes (CNTs) were studied using cyclic voltammetry and constant-potential electrolysis technique, and the CNT-modified electrode was characterized with Fourier transform infrared spectroscopy (FTIR), high resolution transmission electron microscopy (HRTEM) and scanning electron microscopy (SEM) measurements. A CNT-modified packed-bed flow reactor was also constructed for electrocatalytic reduction of nitrobenzene. The results showed that CNTs exhibited high activity for nitrobenzene reduction to aniline and the electrochemical reduction of nitrobenzene at CNT-modified electrode followed the pathway of nitrobenzene-->phenylhydroxylamine-->aniline.
