Mitogen Activated Protein

To clarify the mechanism of piperonyl butoxide (PBO)-induced hepatocarcinogenesis in mice, male mice were subjected to a two-thirds partial hepatectomy, N-diethylnitrosamine (DEN) initiation, and a diet containing 0.6% PBO for eight weeks. The incidence of γ-glutamyl transpeptidase (GGT)-positive foci and PCNA-positive cells was significantly increased in the DEN + PBO group compared with the DEN-alone group. Real-time reverse transcription-polymerase chain reaction (RT-PCR) analysis showed up-regulation of genes related to metabolism, such as cytochrome P450 1A1 and 2B10, and metabolic stress, such as Por, Nqo1, Nrf2, abcc3, and abcc4. Early responsive genes downstream of mitogen-activated protein kinase (MAPK), such as c-fos, c-jun, c-myc, and activating transcription factor 3 ( ATF3), were also up-regulated in this group. Positive immunohistochemical staining for ATF3 was diffusely observed in nonproliferating hepatocytes of the DEN + PBO group, but altered foci were negative or weakly positive for ATF3. The nuclei of hepatocytes within ATF3-negative foci were positive for cyclin D. Thus PBO can induce oxidative stress, activate the MAPK pathway, and increase ATF3 transcript levels in hepatocytes outside the altered foci during the early stage of PBO-induced hepatocarcinogenesis in mice.

Semiconducting Behavior

In this paper, the semiconducting behavior of No.20 carbon steel coated with different polymer coating in 5‰ sulfuric acid solution was studied by utilizing potential-capacitance and Mott-Schottky analysis. It showed that in the same testing condition, the phenol aldehyde resin and epoxy resin showed n-type semiconducting behavior in 5‰ sulfuric acid, whereas for the alkyd resin, it showed p-type semiconducting behavior in 5‰ sulfuric acid solution. It was suggested that the space charge layer of the polymer coating in 5‰ sulfuric acid solution might be asymmetry. It was suggested that at the early stage of immersion, the polymer coating behaved as an insulator, with increasing immersion time, the coating transferred to P-type semiconductor, then to N-type semiconductor.
