The purpose of the present study was to examine whether cAMP-dependent protein kinase (PKA) was implicated in the process of long-term potentiation (LTP) in the hippocampal afferent fibre system to the prefrontal cortex in vivo. Using a biochemical approach, we measured PKA activity at different times after induction of LTP. We show that there is an NMDA(More)
The forkhead box protein 3 (FOXP3) transcription factor is highly expressed in tumor cells as well as in regulatory T cells (Tregs). It plays a tumor-enhancing role in Tregs and suppresses carcinogenesis as a potent repressor of several onco-genes. The clinical prognostic value of FOXP3 expression has not yet been elucidated. In this study,(More)
Rearrangements of anaplastic lymphoma kinase (ALK) have been recently identified in non-small cell lung carcinomas. Previous studies have revealed characteristic features, including adenocarcinoma histology and mucin production, in ALK-positive lung carcinoma. The present study evaluated immunohistochemistry (IHC) in ALK-positive lung carcinoma using two(More)
