<p>Background: It is becoming increasingly recognised that opioids are responsible for tumour growth. However, the effects of opioids on tumour growth have been controversial.Methods:The effects of-opioid receptor (KOR) agonist on the growth of non-small cell lung cancer (NSCLC) cells were assessed by a cell proliferation assay. Western blotting was performed to ascertain the mechanism by which treatment with KOR agonist suppresses tumour growth. Results: Addition of the selective KOR agonist U50,488H to gefitinib-sensitive (HCC827) and gefitinib-resistant (H1975) NSCLC cells produced a concentration-dependent decrease in their growth. These effects were abolished by co-treatment with the selective KOR antagonist nor-BNI. Furthermore, the growth-inhibitory effect of gefitinib in HCC827 cells was further enhanced by co-treatment with U50,488H. With regard to the inhibition of tumour growth, the addition of U50, 488H to H1975 cells produced a concentration-dependent decrease in phosphorylated- glycogen synthase kinase 3Β (p-GSK3Β).Conclusion:The present results showed that stimulation of KOR reduces the growth of gefitinib-resistant NSCLC cells through the activation of GSK3Β. © 2012 Cancer Research UK All rights reserved.</p>

<p>The Great East Japan Earthquake of 2011 seriously jeopardized our collaborative research with Professor Masashi Aoki (Tohoku University School of Medicine) on the development of new therapies for amyotrophic lateral sclerosis (ALS) using hepatocyte growth factor. After the earthquake struck, Professor Aoki made a tremendous contribution to saving patients' lives and to recovering from the disastrous situation. Thanks to his strong leadership and support from many reliable colleagues, we could finally start new clinical trials for ALS patients. In this article, I wish to introduce Professor Aoki's heroic efforts. © 2012 by The Keio Journal of Medicine.</p>

Structure, function and formation of glycans in Drosophila

Yamamoto-Hino Miki, Okano Hideyuki, Kanie Osamu, Goto Satoshi

  165 - 188 2012年02月

　概要を見る

<p>Glycosylation of proteins shows two striking features: first, there are a large number of glycan structures that are involved in various biological events (diversity) and, second, certain structures are selectively added to specific sites within proteins (specificity) in a context-dependent manner. However, the mechanisms that regulate diversity and specificity are unknown. Over the last few decades, genetic studies in Drosophila have been used to examine the functions mediated by glycosylation in vivo. Recent improvements in the combined use of biochemical/biophysical, genetic, and cell biology approaches has allowed the rapid and detailed analysis of the structure, function and formation of glycans in Drosophila. This chapter aims to provide an overview of the different types of glycans and their biological function(s) in Drosophila. The regulation of glycan synthesis in Drosophila and mammals is also discussed. © 2012 by Nova Science Publishers, Inc. All rights reserved.</p>

<p>Once the safety issue has been overcome, induced pluripotent stem cells (iPSCs), which do not entail ethical or immunological concerns, may become the preferred cell source for regenerative medicine. Various types of iPSCs have been established by different methods, and each type exhibits different biological properties. Before iPSC-based clinical applications can be initiated, detailed evaluations of the cells, including their differentiation potentials and tumorigenic activities in different contexts, should be investigated to establish their safety and effectiveness for cell transplantation therapies. Recently, we demonstrated the directed neural differentiation of mouse iPSCs and examined their therapeutic potential in a mouse spinal cord injury (SCI) model. Mouse iPSC-derived neural stem/progenitor cells (NS/PCs), which had been pre-evaluated as non-tumorigenic by their transplantation into nonobese diabetic-severe combined immunodeficiency (NOD-scid) mouse brain, were transplanted into the spinal cord 9 days after SCI. Mouse iPSC-derived NS/PCs differentiated into all three neural lineages without forming teratomas or other tumors. They also participated in re-myelination and induced the axonal re-growth, promoting motor functional recovery. Nevertheless, our results constitute only the first step toward clinical application. The safety and effectiveness of human iPSC-derived NS/PCs need to be more intensively investigated in future preclinical studies, for example, using non-human primate SCI models. In particular, human iPSCs established by delivering reprogramming factors using a safer method than retrovirus system, such as an integration-free virus system, virus-free system, or transgene-free system should be evaluated.</p>

<p>Examples of direct differentiation by defined transcription factors have been provided for beta-cells, cardiomyocytes and neurons. In the human visual system, there are four kinds of photoreceptors in the retina. Neural retina and iris-pigmented epithelium (IPE) share a common developmental origin, leading us to test whether human iris cells could differentiate to retinal neurons. We here define the transcription factor combinations that can determine human photoreceptor cell fate. Expression of rhodopsin, blue opsin and green/red opsin in induced photoreceptor cells were dependent on combinations of transcription factors: A combination of CRX and NEUROD induced rhodopsin and blue opsin, but did not induce green opsin; a combination of CRX and RX induced blue opsin and green/red opsin, but did not induce rhodopsin. Phototransduction-related genes as well as opsin genes were up-regulated in those cells. Functional analysis; i.e. patch clamp recordings, clearly revealed that generated photoreceptor cells, induced by CRX, RX and NEUROD, responded to light. The response was an inward current instead of the typical outward current. These data suggest that photosensitive photoreceptor cells can be generated by combinations of transcription factors. The combination of CRX and RX generate immature photoreceptors: and additional NEUROD promotes maturation. These findings contribute substantially to a major advance toward eventual cell-based therapy for retinal degenerative diseases.</p>
