Abstract
Epidermal growth factor receptor (EGFR) overexpression and EGFR-mediated signaling pathway dysregulation have been observed in tumors from patients with various cancers, especially non-small cell lung cancer. Thus, several anti-EGFR drugs have been developed for cancer therapy. For patients with known EGFR activating mutations (EGFR exon 19 in-frame deletions and exon 21 L858R substitution), treatment with an EGFR tyrosine kinase inhibitor (EGFR TKI; gefitinib, erlotinib or afatinib) represents standard first-line therapy. However, the clinical efficacy of these TKIs is ultimately limited by the development of acquired drug resistance such as by mutation of the gatekeeper T790 residue (T790M). To overcome this acquired drug resistance and develop novel anti-EGFR drugs, a cell-based assay system for EGFR TKI resistance mutant-selective inhibitors is required. We constructed a novel cell-based assay for the evaluation of EGFR TKI efficacy against EGFR mutation. To this end, we established non-tumorigenic immortalized breast epithelial cells that proliferate dependent on EGF (MCF 10A cells), which stably overexpress mutant EGFR. We found that the cells expressing EGFR containing the T790M mutation showed higher resistance against gefitinib, erlotinib and afatinib compared with cells expressing wild-type EGFR. In contrast, L858R mutant-expressing cells exhibited higher TKI sensitivity. The effect of T790M-selective inhibitors (osimertinib and rociletinib) on T790M mutant-expressing cells was significantly higher than gefitinib and erlotinib. Finally, when compared with commercially available isogenic MCF 10A cell lines carrying introduced mutations in EGFR, our EGFR mutant-overexpressing cells exhibited obviously higher responsiveness to EGFR TKIs depending on the underlying mutations because of the higher levels of EGFR phosphorylation in the EGFR mutant-overexpressing cells than in the isogenic cell lines. In conclusion, we successfully developed a novel cell-based assay for evaluating the efficacy of anti-EGFR drugs against EGFR mutation.

Abstract
Screening for oncogenes has mostly been performed by in vitro transformation assays. However, some oncogenes might not exhibit their transforming activities in vitro unless putative essential factors from in vivo microenvironments are adequately supplied. Here, we have developed an in vivo screening system that evaluates the tumorigenicity of target genes. This system uses a retroviral high-efficiency gene transfer technique, a large collection of human cDNA clones corresponding to ~70% of human genes and a luciferase-expressing immortalized mouse mammary epithelial cell line (NMuMG-luc). From 845 genes that were highly expressed in human breast cancer cell lines, we focused on 205 genes encoding membrane proteins and/or kinases as that had the greater possibility of being oncogenes or drug targets. The 205 genes were divided into five subgroups, each containing 34-43 genes, and then introduced them into NMuMG-luc cells. These cells were subcutaneously injected into nude mice and monitored for tumor development by in vivo imaging. Tumors were observed in three subgroups. Using DNA microarray analyses and individual tumorigenic assays, we found that three genes, ADORA2B, PRKACB and LPAR3, were tumorigenic. ADORA2B and LPAR3 encode G-protein-coupled receptors and PRKACB encodes a protein kinase A catalytic subunit. Cells overexpressing ADORA2B, LPAR3 or PRKACB did not show transforming phenotypes in vitro, suggesting that transformation by these genes requires in vivo microenvironments. In addition, several clinical data sets, including one for breast cancer, showed that the expression of these genes correlated with lower overall survival rate.

Abstract
Gene amplification can be a cause of cancer, and driver oncogenes have been often identified in amplified regions. However, comprehensive analysis of other genes coamplified with an oncogene is rarely performed. We focused on the 17q12-21 amplicon, which contains ERBB2. We established a screening system for oncogenic activity with the NMuMG epithelial cell line. We identified a homeobox gene, HNF1B, as a novel cooperative transforming gene. HNF1B induced cancerous phenotypes, which were enhanced by the coexpression of ERBB2, and induced epithelial-to-mesenchymal transition and invasive phenotypes. These results suggest that HNF1B is a novel oncogene that can work cooperatively with ERBB2.

Abstract
A spinal cord injury leads to disturbances of sensory and motor signals due to the damage to white matter and myelinated fiber tracts. Moreover, the damage to gray matter causes segmental loss of interneurons of dorsal horn and motoneurons and restricts the therapeutic options. Neuroprotective strategies have the potential to improve the neurological outcome of patients. To achieve this, concerns to anesthetics or analgesics as neuroprotective interventions have been accumulating to explore neuroprotection during perioperative period. This review includes consideration of: 1) basic concepts of the pathophysiological mechanisms following spinal cord injury and 2) anesthetics and analgesics displaying neuroprotective potential. In particular, we review the application of isoflurane as an inhalational neuroprotectant and discuss evidence for the neuroprotection provided by barbiturates. In addition, 3) recent advances in stem cell biology, neural injury and repair, and progress toward the development of neuroprotective and regenerative interventions are the basis for increased optimism.

Abstract
Between Aril 1975 and December 1976, the second nationwide survey of Meniere's disease in Japan was made by the 17 members of the Meniere's Disease Research Committee of Japan. The epidemiological data from 520 patients with definite Meniere's disease were analyzed in comparison with those from the 126 patients in the non-Meniere vertiginous group (Control A) and the 228 patients in the rhinolaryngological group (Control B). The male:female ratio of definite cases of Meniere's disease was almost the same, and the age distribution peaked at the age group of 40--49 years for males, while the peak for females was at the age group of 30--39 years. 5.8% of the 520 patients had a close relative who also suffered from Meniere's disease. From the epidemiological features, it may appear that the occurrence of vertiginous attacks in Meniere's disease is influenced much more by individual than by environmental factors. However, this feature can be considered as another evidence of the psychosomatic disorders involved in Meniere's disease.

Abstract
Type 2 diabetes results from the failure of beta-cells to adequately compensate for insulin resistance. Although the reduction of beta-cell mass is because of increased cell death and/or inadequate replication or neogenesis, the mechanism underlying beta-cell mass reduction is not fully understood. Here, we clarify the role of insulin signaling pathway in the beta-cell apoptosis using insulin resistant model mice. Wild-type mice and those carrying a mutation in the insulin receptor (mIR) were fed either regular chow or a high-fat diet for 6 weeks and subsequently investigated for beta-cell apoptosis, endoplasmic reticulum stress, and oxidative stress. Insulin tolerance tests revealed that mIR mice fed a high-fat diet (mIRHF) had higher insulin resistance. Beta-cell apoptosis was increased 2-fold in the wild-type mice fed a high-fat diet (wHF) compared with control mice, whereas beta-cell apoptosis in mIRHF mice did not increase compared with that in mIR mice. The expression of endoplasmic reticulum stress markers in isolated islets did not differ between the groups. Staining of 8-hydroxy-2'-deoxyguanosine and 4-hydroxy-2-nonenal in islets of wHF mice significantly increased, but the staining in mIRHF mice was not different from that in control group. Gene expression of the antioxidant enzyme MnSOD was significantly higher in mIRHF mice than those in the other 3 groups. A mutation in the insulin receptor attenuated the oxidative stress and apoptosis in beta-cells even though high caloric nutrient was loaded. Our results suggest that reduced insulin signaling protects beta-cells thorough decline of oxidative stress.

Abstract
The early steps of mammary tumorigenesis include loss of epithelial cell polarity, escape from anoikis, and acquisition of proliferative capacity. The genes responsible for these processes are predicted to be early diagnostic markers or new therapeutic targets. Here we tested 51 genes coamplified with ERBB2 in the 17q12-21 amplicon for these tumorigenic activities using an MCF10A 3D culture-based screening system. We found that overexpression of retinoic acid receptor α (RARA) disrupted normal acinar structure and induced epithelial-to-mesenchymal transition (EMT). The mRNA levels of known EMT-inducing factors, including SLUG, FOXC2, ZEB1, and ZEB2, were significantly increased upon RARA overexpression. Knockdown of ZEB1 suppressed the RARA-mediated EMT phenotype. These results suggest that overexpression of RARA enhances malignant transformation during mammary tumorigenesis.

Abstract
We assessed the efficacy and safety of sitagliptin compared with α-glucosidase inhibitor (αGI) in 120 of Japanese patients with type 2 diabetes mellitus (T2DM) inadequately controlled on stable ≤2 mg/day glimepiride alone [mean hemoglobin A1c (HbA1c) 7.7%] by the randomized, active-controlled, non-inferiority trial. Patients were randomly assigned to receive additional sitagliptin or αGI for 24 weeks. The primary endpoint was change in HbA1c from baseline to week 12. After 12 weeks, sitagliptin reduced HbA1c by -0.44% (p < 0.001) relative to αGI. At 24 weeks, the reduction was almost identical between the groups (-0.091%, p = 0.47). Gastrointestinal disorders were more common with αGI than with sitagliptin, but only minor hypoglycaemia occurred in both groups at similar frequency. These data suggested that sitagliptin was not inferior to αGI for reduction of HbA1c in Japanese T2DM patients receiving glimepiride alone, and well tolerated with minimum risk of gastrointestinal symptoms and hypoglycaemia.
