Abstract
Abstract
The notoriously high proliferation rate of cancer cells requires them to constantly deal with the balance adjustment between oxidative stress overload and upregulated protective antioxidant pathways. It puts them in a vulnerable state whenever one piece of this puzzle went out of control. Non-thermal plasma (NTP) is partially ionized gas operated at or around body temperature and has emerged as a new potential anti-cancer therapy due to its ability to release and induce ROS, RNS, and other free radicals as well as generate UV- photon and electromagnetic field; but the specific mechanism and its specificity to cancer cell are still controversial. Using transcriptomic analysis, we previously reported the link between NTP-activated media (NTPAM)and apoptosis; but the sequencing data also revealed a strong Ferroptotic response in all the 6Head and Neck cancer cell lines we checked. Ferroptosis is a newly identified oxidative-regulated cell death, characterized by the iron-dependent generation of lipid peroxidation. In this study, we found the prolonged treatment of NTPAM-induced cell death via the non-canonical ferroptosis pathway by directly increasing intracellular toxic ferrous Iron (Fe2+). We found that the excessive overexpression of HMOX1 under prolonged NTPAM-induced oxidative stress was actually responsible for the surge of intracellular Fe2+ due to the increase of heme degradation. Pharmacological inhibition or RNA silencing of HMOX1 was able to rescue 2 HNC cell lines from NTPAM-induced increased Iron concentration as well as ferroptosis cell death, both in vivo and in vitro. These results suggest NTP directly induces ferroptosis via an increase of Fe2+ concentration by triggering the over-responding of the NRF2 - HMOX1 antioxidant system. This finding could be exploited to develop future NTP-based cancer therapy as well as in combination with other Iron sensitive anti-neoplastic agents; and could be a potential method of overcoming conventional cancer treatment resistance.

Abstract
Objectives The mitochondrial ribosomal protein L14 (MRPL14) is encoded by a nuclear gene and participates in mitochondrial protein translation. In this study, we aimed to investigate the role of MRPL14 in thyroid carcinoma. Methods We investigated the association of expression of MRPL14 and clinicopathological features using the The Cancer Genome Atlas (TCGA) and Chungnam National University Hospital (CNUH) databases. Functional studies of MRPL14, including proliferation, migration, invasion, mitochondrial oxidative phosphorylation and reactive oxygen species (ROS) production, were performed in papillary thyroid carcinoma (PTC) cell lines (B-CPAP and KTC-1). Results Based on TCGA dataset, PTC tissues lost mitochondrial integrity and showed dysregulated expression of overall mitoribosomal proteins (MRPs) compared with normal thyroid tissues. Of 78 MRPs, MRPL14 was highly expressed in thyroid carcinoma tissues. MRPL14 overexpression was significantly associated with advanced tumor stage, extrathyroidal extension, and lymph node metastasis. MRL14 increased cell proliferation of thyroid cancer and promoted cell migration via epithelial-mesenchymal transition-related proteins. Moreover, MRPL14 knockdown reduced the expression of oxidative phosphorylation complex IV (MTCO1) and increased the accumulation of ROS. Co-treatment with a ROS scavenger restored cell proliferation and migration reduced by MRPL14 knockdown, which imply that ROS functions as a key regulator of the oncogenic effects of MRPL14 in thyroid cancer cells. Conclusion Our findings indicate that MRPL14 may promote cell growth, migration, and invasion through modulating ROS in thyroid cancer cells.

Abstract
OBJECTIVE This study aimed to determine whether completion thyroidectomy is necessary based on long-term follow-up oncological results according to various clinical and pathological characteristics of patients with papillary thyroid carcinoma (PTC) who underwent lobectomy. MATERIALS AND METHODS We enrolled 1815 patients with PTC who underwent thyroid lobectomy from January 2003 to December 2014. Various clinical and pathological characteristics were reviewed retrospectively, and clinicopathologic characteristics and recurrence rates were analyzed. RESULTS Eighty-two (4.5%) patients showed locoregional recurrence during the average 10.2-year follow-up period. There was no significant difference in tumor size, multifocality, lymphovascular invasion (LVI), microscopic or strap muscle-extrathyroidal extension, and central neck lymph node (LN) micrometastasis between the recurrence and non-recurrence groups. The gross strap muscle-extrathyroidal extension group was associated with older age (p < 0.001), larger tumor size (p < 0.001), more capsular invasion (p < 0.001), and more LVI (p < 0.001) than the negative extrathyroidal extension group; there was no significant difference in recurrence between the groups (p = 0.096). Patients with five or more central LN micrometastases were associated with younger age (p = 0.006), larger tumor size (p = 0.04), and presence of LVI (p = 0.033) than patients with less than five central LN metastases; there was no significant difference in recurrence between the groups (p = 0.867). All patients with recurrence were cured through reoperation after recurrence was confirmed. CONCLUSION After thyroid lobectomy, PTC patients with multifocality, LVI, extrathyroidal extension to the strap muscles, or five or more central LN micrometastases may not require immediate completion thyroidectomy.

Abstract
Claudin-1 (CLDN1), a major component of tight junction complexes in the epithelium, maintains cellular polarity, and plays a critical role in cell-to-cell communication as well as epithelial cell homeostasis. Although the role of CLDN1 has been widely studied in cancer, its role in the progression and the exact regulatory mechanisms, remain controversial. Using next-generation sequencing, we first analyzed the expression profiles of tumor/non-tumor paired tissue in patients with head and neck squamous cell carcinoma (HNSC) from public and local cohorts and found out that CLDN1 is upregulated in tumors compared to normal tissues. Next, its correlation with lymph node metastasis and poor prognosis was validated in the retrospective cohort, which collectively suggests CLDN1 as an oncogene in HNSC. As expected, the knockdown of CLDN1 inhibited invasive phenotypes by downregulating epithelial-to-mesenchymal transition (EMT) in vitro. To ascertain the regulatory mechanism of CLDN1 in HNSC analysis of GO term enrichment, KEGG pathways, and curated gene sets were used. As a result, CLDN1 was negatively associated with AMP-activated protein kinase (AMPK) and positively associated with transforming growth factor-β (TGF-β) signaling. In vitro mechanistic assay showed that CLDN1 inhibited AMPK phosphorylation by regulating AMPK upstream phosphatases, which led to inhibition of Smad2 activity. Intriguingly, the invasive phenotype of cancer cells increased by CLDN1 overexpression was rescued by AMPK activation, indicating a role of the CLDN1/AMPK/TGF-β/EMT cascade in HNSC. Consistently in vivo, CLDN1 suppression significantly inhibited the tumor growth, with elevated AMPK expression, suggesting the novel observation of oncogenic CLDN1-AMPK signaling in HNSC.

Abstract
Various enzymes in the one-carbon metabolic pathway are closely related to the development of tumors, and they can all be potential targets for cancer therapy. Serine hydroxymethyltransferase2 (SHMT2), a key metabolic enzyme, is very important for the proliferation and growth of cancer cells. However, the function and mechanism of SHMT2 in head and neck cancer (HNC) are not clear. An analysis of The Cancer Genome Atlas (TCGA) data showed that the expression of SHMT2 was higher in tumor tissue than in normal tissue, and its expression was significantly associated with male sex, aggressive histological grade, lymph node metastasis, distant metastasis, advanced TNM stage, and lymphovascular invasion in HNC. SHMT2 knockdown in FADU and SNU1041 cell lines significantly inhibited cell proliferation, colony formation, migration, and invasion. Additionally, Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analyses using TCGA data revealed that SHMT2 was closely related to cancer stem cell regulation and maintenance. Furthermore, we found that silencing SHMT2 inhibited the expression of stemness markers and tumor spheroid formation compared with a control group. On the contrary, stemness markers were significantly increased after SHMT2 overexpression in HEP-2 cells. Interestingly, we found that knocking down SHMT2 reduced the expression of genes related to the Notch and Wnt pathways. Finally, silencing SHMT2 significantly reduced tumor growth and decreased stemness markers in a xenograft model. Taken together, our study suggests that targeting SHMT2 may play an important role in inhibiting HNC progression.

Abstract
BACKGROUND Despite recent advances in understanding the complex immunologic dysfunction in the tumor microenvironment (TME), fewer than 20% of patients with head and neck squamous cell carcinoma (HNSCC) respond to immune checkpoint blockade (ICB). Thus, it is important to understand how inhibitory IC receptors maintain the suppressed dysfunctional TME, and to develop more effective combination immunotherapy. This study evaluated the immune-modulating effects of Curcumin, which has well-established anti-cancer and chemopreventive properties, and its long-term safety as a phytochemical drug. METHODS We carried out the western blot and small interfering RNA (siRNA) transfection assay to evaluate the effects of Curcumin on IC ligands and IC ligands function in HNSCC. Through T-cell cytotoxicity assay and measurements of cytokine secretion, we assessed the effects of combination of Curcumin with programmed death-ligand 1 (PD-L1) Ab on cancer cell killing. Flow cytometry were used to analyze the effects of Curcumin on the expression of programmed cell death protein 1 (PD-1) and T-cell immunoglobulin and mucin-domain3 (TIM-3) on CD4, CD8 and Treg. Immunofluorescence, immunohistochemistry and western blot were used to detecte the cytokine (IFN-γ, Granzyme B), IC receptors (PD-1 and TIM-3) and its ligands (PD-L1, PD-L2, Galectin-9) in xenograft mouse model and 4-nitroquinoline-1-oxide (4-NQO) oral cancer model. RESULTS We found that Curcumin decreased the expression of IC ligands such as PD-L1, PD-L2, and Galectin-9 in HNSCC, leading to regulation of epithelial-to-mesenchymal transition-associated tumor invasion. Curcumin also effectively restored the ability of CD8+ cytotoxic T cells to lyse cancer cells. To evaluate the effect of Curcumin on the TME further, the 4-NQO oral cancer model was used. Curcumin increased T-cell proliferation, tumor-infiltrating lymphocytes (TILs), and effector cytokines, and decreased the expression of PD-1, TIM-3, suppressive IC receptors and their ligands (PD-L1, PD-L2, and Galectin-9) in the TME, implying reinvigoration of the exhausted CD8+ T cells. In addition, Curcumin inhibited expression of CD4+CD25+FoxP3+ Treg cells as well as PD-1 and TIM-3. CONCLUSIONS These results show that Curcumin reinvigorates defective T cells via multiple (PD-1 and TIM-3) and multi-level (IC receptors and its ligands) IC axis suppression, thus providing a rationale to combine Curcumin with conventional targeted therapy or ICB as a multi-faceted approach for treating patients with HNSCC.

Abstract
Growth and differentiation factor 15 (GDF15), a divergent member of the transforming growth factor-β (TGF-β) superfamily, has been reported to be overexpressed in different kinds of cancer types. However, the function and mechanism of GDF15 in head and neck cancer (HNC) remains unclear. The Cancer Genome Atlas (TCGA) data show that the expression of GDF15 is significantly associated with tumor AJCC stage, lymph vascular invasion and tumor grade in HNC. In this study, we confirmed that knockdown of GDF15 attenuated: cell proliferation, migration and invasion via regulation of EMT through a canonical pathway; SMAD2/3 and noncanonical pathways; PI3K/AKT and MEK/ERK in HNC cell lines. Furthermore, we found that early growth response 1 (EGR1) was a transcription factor of GDF15. Interestingly, we also demonstrated that GDF15 could regulate the expression of EGR1, which meant a positive feedback loop occurred between these two factors. Moreover, combined inhibition of both GDF15 and EGR1 in a HNC mouse xenograft model showed significantly decreased tumor volume compared to inhibition of EGR1 or GDF15 alone. Our study showed that the GDF15–EGR1 signaling axis may be a good target in HNC patients.

Abstract
SummaryAn Arg91Gln substitution in the mature von Willebrand factor (vWF) has been associated with defective binding of vWF to factor VIII (FVIII). We studied four families with members initially classified as having type I von Willebrand disease (vWD) who were either homozygous or heterozygous for the Arg91Gln change. The first family was the original case described by Nishino et al. (1) where three members were homozygous for the Gln91 allele. They had a low FVIII coagulant activity:vWF antigen (VIIIC:vWFAg) ratio, from 0.29 to 0.44, and the ability of their plasma vWF to bind FVIII was markedly decreased. All the heterozygous members had normal vWF and FVIII levels but the capacity of their plasma vWF to bind FVIII was reduced and intermediate between the homozygous members and normals. The affected individual from the second family was heterozygous for the Gln91 allele and demonstrated a VIIIC:vWFAg ratio of 0.98. The FVIII binding assay confirmed the heterozygous status indicating that the moderately low levels of vWF were due to reduced expression of both alleles. The propositus from the third family was also heterozygous and had below normal levels of vWF as well as a low VIIIC:vWFAg ratio of 0.34; however, FVIII binding to her plasma vWF was similar to that of the homozygous individuals suggesting that Gln91-vWF was the major circulating form. Her daughter who has type I vWD inherited the allele without the Gln91 mutation indicating that the expression of this allele was indeed impaired. The heterozygous patient in the fourth family had a vWF level of 24 U/dl but an VIIIC:vWFAg ratio greater than 2. Her plasma vWF showed normal FVIII binding implying that the Gln91 mutation was linked to a defect that repressed the expression of the allele. The Arg91Gln substitution appears to decrease but not eradicate FVIII binding suggesting a critical concentration of vWF be attained before the defect becomes phenotypically important.

Abstract
We introduce a new procedure for the efficient isolation and subsequent separation of double-wall carbon nanotubes (DWCNTs). A simplified, rate zonal ultracentrifugation (RZU) process is first applied to obtain samples of highly-enriched DWCNTs from a raw carbon nanotube material that has both single- and double-wall carbon nanotubes. Using this purified DWCNT suspension, we demonstrate for the first time that DWCNTs can be further processed using aqueous two-phase extraction (ATPE) for sequential separation by electronic structure and diameter. Additionally, we introduce analytical ultracentrifugation (AUC) as a new method for DWCNT characterization to assess DWCNT purity in separated samples. Results from AUC analysis are utilized to compare two DWCNT separation schemes. We find that RZU processing followed by sequential bandgap and diameter sorting via ATPE provides samples of highest DWCNT enrichment, whereas single-step redox sorting of the same raw material through ATPE yields SWCNT/DWCNT mixtures of similar diameter and electronic character. The presented methods offer significant advancement in DWCNT processing and separation while also providing a promising alternative for DWCNT sample analysis.

Abstract
Chemical control of the endohedral volume of single-wall carbon nanotubes (SWCNTs) via liquid-phase filling is established to be a facile strategy to controllably modify properties of SWCNTs in manners significant for processing and proposed applications. Encapsulation of over 20 different compounds with distinct chemical structures, functionalities, and effects is demonstrated in SWCNTs of multiple diameter ranges, with the ability to fill the endohedral volume based on the availability of the core volume and compatibility of the molecule's size with the cross-section of the nanotube's cavity. Through exclusion of ingested water and selection of the endohedral chemical environment, significant improvements to the optical properties of dispersed SWCNTs such as narrowed optical transition linewidths and enhanced fluorescence intensities are observed. Examples of tailoring modified properties towards applications or improved processing by endohedral passivation are discussed.

Abstract
To simulate clinical trials to assess overall survival (OS) benefit of bevacizumab in combination with chemotherapy in selected patients with gastric cancer (GC), a modeling framework linking OS with tumor growth inhibition (TGI) metrics and baseline patient characteristics was developed. Various TGI metrics were estimated using TGI models and data from two phase III studies comparing bevacizumab plus chemotherapy vs. chemotherapy as first‐line therapy in 976 GC patients. Time‐to‐tumor‐growth (TTG) was the best TGI metric to predict OS. TTG, Eastern Cooperative Oncology Group (ECOG) score, albumin level, and Asian ethnicity were significant covariates in the final OS model. The model correctly predicted a decreased hazard ratio favorable to bevacizumab in patients with high baseline plasma VEGF‐A above the median of 113.4 ng/L. Based on trial simulations, in trials enrolling patients with elevated baseline plasma VEGF‐A (500 patients per arm), the expected hazard ratio was 0.82 (95% prediction interval: 0.70–0.95), independent of ethnicity.

Abstract
BACKGROUND Recent evidence has shown clinical phenotypic heterogeneity of inherited prion diseases, even between patients harbouring the same mutation in the PRNP gene. OBJECTIVE AND METHODS We collected clinical data from a Chinese family with autosomal dominant dementia and screened the PRNP gene on 28 living members. A stereotactic biopsy of the right frontal lobe of the proband was performed. RESULTS The family comprised four affected individuals within two successive generations. The age of onset was in 30 or 40 s, and the duration was about 2-3 years. Clinical features of the affected members included neuropsychiatric disturbances, progressive dementia and extrapyramidal symptoms. Immunostaining for prion protein showed fine granular deposits of PrP(sc) in the neuropil. The PRNP gene analysis demonstrated a heterozygous G114V mutation in 15 family members. The proband was diagnosed as familial Creutzfeldt-Jakob disease (fCJD). CONCLUSION This study strengthens the linkage of the G114V mutation to CJD. It supports the worldwide distribution of fCJD despite differences in genetic background.

Abstract
2029 Background: Aflibercept is a recombinant fusion protein that scavenges both vascular endothelial growth factor (VEGF) and placental growth factor (PlGF). In a single-arm phase II study (NABTC06–01; NCT00369590 ), a 22% response rate was seen in recurrent glioblastoma patients receiving aflibercept 4 mg/kg iv every 2 weeks. We performed detailed analyses of circulating and urinary cytokine and angiogenic factors to describe the modulation of markers in response to aflibercept and to identify potential predictive markers. Methods: Plasma samples were collected from 31 of 32 enrolled patients at baseline, 24 hours and every 2–4 weeks until progression. Urine samples were collected at baseline and every 4 weeks. Levels of 41 circulating factors were measured using suspension bead multiplex assays (BioRad) or ELISA. Free VEGF and PlGF levels were determined following sample immunodepletion. Baseline and changes in marker levels over time were correlated with response and progression using logistic regression and Cox proportion hazard models. Results: Treatment with aflibercept resulted in significant increases in total VEGF and PlGF at 24 hours and 28 days (p ≤ 0.001). Free VEGF was rapidly sequestered by 24 hours and remained significantly decreased at 28 days (p = 0.001). However, free PlGF levels rose over time and by 28 days were 45-fold higher than baseline (p < 0.001). Additional modulation of 4 factors at 24 hours included decreases in Groα and MIF (p = 0.001) and increases in urinary VEGF and MIP1β (p ≤ 0.001). At 28 days, levels of IL-18 were significantly decreased (p = 0.02) while SCGFβ and urinary VEGF levels increased (both p < 0.02). Comparing baseline biomarker levels between response groups (PD, SD, and PR), patients with lower levels of GROα, HGF, SCGFβ and higher levels of free VEGF were more likely to have a PR (all p < 0.05). Conclusions: In recurrent glioblastoma, aflibercept resulted in rapid and sustained decreases in free VEGF levels. Although greater than 95% of PlGF remained bound, free PlGF levels significantly increased over time. Treatment significantly modulated multiple cytokine and angiogenic factors with striking increases in MIF and SCGFβ. Potential biomarkers predictive of response to aflibercept include Groα, HGF and SCGFβ. No significant financial relationships to disclose.

Abstract
The fact that glioblastomas, which are one of the most devastating cancers, frequently express the Delta-EGFR (epithelial growth factor receptor) also called mutant variant III of EGFR (EGFRvIII) suggests that this cancer cell-specific receptor might serve as an ideal target for cancer therapy. To assess its potential as such a target, we constructed an oncolytic adenovirus with Retargeted Infectivity Via EGFR (Delta-24-RIVER) on the backbone of Delta-24. This new oncolytic adenovirus targets, as Delta-24 does, the disrupted Rb pathway in cancer cells; in addition, this adenovirus has also been retargeted through the abrogation of CAR binding (Y477A mutation in adenoviral fiber protein) and insertion of an EGFRvIII-specific binding peptide in the HI loop of the fiber protein. As compared with Delta-24, Delta-24-RIVER induced EGFRvIII-selective cytotoxicity in U-87 MG isogenic cell lines and in tetracycline-inducible EGFRVIII expressing U-251 MG cells. Accordingly, by tittering the viral progeny and examining fiber protein expression in the above cells, we showed that the replication of this new construct also correlated with EGFRvIII expression. Consistently, immunohistochemistry staining of the adenoviral capsid protein hexon in the virus-treated tumors revealed that the virus replicated more efficiently in EGFRvIII-expressing U-87 MG.DeltaEGFR xenografts than in the tumors grown from U-87 MG cells. Importantly, treatment with Delta-24-RIVER prolonged the survival of animals with intracranial xenografts derived from U-87 MG.DeltaEGFR cells. Therefore, our results constitute the first proof of the direct targeting of a cancer-specific receptor using an oncolytic adenovirus.

Abstract
Angiogenesis is thought to depend on a perfectly coordinated balance between endogenous-positive and negative regulatory factors. Of these factors, the vascular endothelial growth factor (VEGF) and angiopoietins (Angs) seem to play an essential role. Recently, we reported the expression of the Ang-natural receptor, Tie2, in neoplastic astrocytic cells within gliomas. Because of the VEGF/Ang2 functional partnership together with the presence of Tie2 in gliomas, we hypothesized a role of Ang2 on the modulation of VEGF levels in these tumors. We examined the effect of Ang2 on VEGF expression in a panel of glioma cells, which showed that Ang2 inhibited VEGF expression at both mRNA and protein levels in Tie2-expressing cells, but not in Tie2-negative cells. VEGF promoter analysis showed that Ang2 regulated VEGF expression at the transcriptional level in relation to a decrease in HIF-1alpha expression and HIF-DNA-binding activity. Tie2 silencing by siRNA rescued the Ang2-mediated downmodulation of VEGF, suggesting an essential role for Tie2 in this regulatory loop. To our knowledge, this is the first report on the role of Ang2/Tie2 in the regulation of HIF-1alpha/VEGF expression, providing additional evidence of the intrinsic coordination that occurs among these factors during angiogenesis.

Abstract
Novel therapies are clearly needed for gliomas, and the combination of oncolytic vectors with chemotherapy possesses a significant hope for the treatment of this malignancy. In addition, combination with chemotherapy allows for lower virus doses to achieve anticancer effect, thus resulting in lower undesirable toxicities due to viral proteins. In this work, we sought to determine whether combination of an oncolytic adenovirus ICOVIR-5, with RAD001 or temozolomide (TMZ) could result in enhanced anti-glioma effect in vivo. We assessed the in vitro cytotoxic effect and replication properties of ICOVIR-5 in combination with RAD001 or TMZ in U87 MG glioma cell line by MTT and TCID(50), respectively. Our data showed that in vitro treatment with RAD001 or TMZ not only interfered with adenovirus replication but, in addition, enhanced its oncolytic properties. To evaluate the in vivo anticancer effect, athymic mice bearing glioma xenografts (5 x 10(5) U87 MG cells/animal) received a single intratumoral injection of ICOVIR-5 (10(7) PFU/animal). RAD001 was given as a regimen of 5 mg/kg 5 days per week until the end of the experiment and TMZ was administered for 5 days at 7.5 mg/kg/mice. Of significance, combination of ICOVIR-5 with RAD001 or TMZ showed a potent anti-glioma effect in vivo, resulting in a dramatic extension of the median animal survival and in 20-40% animals becoming free of disease beyond 90 days.

Abstract
A series of Ca(2+) oscillations during mammalian fertilization is necessary and sufficient to stimulate meiotic resumption and pronuclear formation. It is not known how effectively development continues in the absence of the initial Ca(2+) signal. We have triggered parthenogenetic egg activation with cycloheximide that causes no Ca(2+) increase, with ethanol that causes a single large Ca(2+) increase, or with Sr(2+) that causes Ca(2+) oscillations. Eggs were co-treated with cytochalasin D to make them diploid and they formed pronuclei and two-cell embryos at high rates with each activation treatment. However, far fewer of the embryos that were activated by cycloheximide reached the blastocyst stagecompared tothose activated by Sr(2+) orethanol. Any cycloheximide-activated embryos that reached the blastocyst stage had a smaller inner cell mass number and a greater rate of apoptosis than Sr(2+)-activated embryos. The poor development of cycloheximide-activated embryos was due to the lack of Ca(2+) increase because they developed to blastocyst stages at high rates when co-treated with Sr(2+) or ethanol. Embryos activated by either Sr(2+) or cycloheximide showed similar signs of initial embryonic genome activation (EGA) when measured using a reporter gene. However, microarray analysis of gene expression at the eight-cell stage showed that activation by Sr(2+) leads to a distinct pattern of gene expression from that seen with embryos activated by cycloheximide. These data suggest that activation of mouse eggs in the absence of a Ca(2+) signal does not affect initial parthenogenetic events, but can influence later gene expression and development.

Abstract
Due to brain tissue heterogeneity, the molecular genetic profile of any neurotransmitter-specific neuronal subtype is unknown. The purpose of this study was to purify a population of dopamine neurons, construct a cDNA library, and generate an initial gene expression profile and a microarray representative of dopamine neuron transcripts. Ventral mesencephalic dopamine neurons were purified by fluorescent-activated cell sorting from embryonic day 13.5 transgenic mice harboring a 4.5-kb rat tyrosine hydroxylase promoter-lacZ fusion. Nine-hundred sixty dopamine neuron cDNA clones were sequenced and arrayed for use in studies of gene expression changes during methamphetamine neurotoxicity. A neurotoxic dose of methamphetamine produced a greater than twofold up-regulation of the mitochondrial cytochrome c oxidase polypeptide I transcript from adult mouse substantia nigra at 12 h posttreatment. This is the first work to describe a gene expression profile for a neuronal subtype and to identify gene expression changes during methamphetamine neurotoxicity.

Abstract
Here we report a novel design of linker primer that allows one to differentially amplify long tracts (average 3.0 kb with size ranges of 1-7 kb) or short DNAs (average 1.5 kb with size ranges of 0.5-3 kb) from a complex mixture. The method allows one to generate cDNA libraries enriched for long transcripts without size selection of insert DNAs. One representative library from newborn kidney includes 70% of clones bearing ATG start codons. A comparable library has been generated from 20 mouse blastocysts, containing only approximately 40 ng of total RNA. This universal PCR amplification scheme can provide a route to isolate very large cDNAs, even if they are expressed at very low levels.

Abstract
OBJECTIVE To evaluate the effect and safety of early moderate hypothermia therapy (MHT) on patients with head injury by using parallel-control test. METHODS Thirty patients with severe head injury within 6 hours after accidents were treated by MHT generally for 4-10 days. The other 30 patients with similar head injury treated routinely were enrolled for a parallel-control test. The mortality, morbidity and changes of some neuro-functional indexes as Glasgow Coma Scores, and Glasgow Outcome Scale, levels of endothelin and some other factors of neurobiochemistry in blood plasma were observed. Meanwhile, the dynamic monitoring by transcranial Doppler ultrasonography was conducted in these patients. RESULTS The mortality in MHT group was significantly lower than that in control group. MHT not only reduced endothelin but also increased the brain biochemical factors, which were helpful to the protection of neurons in the early brain ischemia after head injury. CONCLUSIONS Early MHT can help reduce mortality and morbidity in patients with acute head injury.

Abstract
cDNA microarray technology has been increasingly used to monitor global gene expression patterns in various tissues and cell types. However, applications to mammalian development have been hampered by the lack of appropriate cDNA collections, particularly for early developmental stages. To overcome this problem, a PCR-based cDNA library construction method was used to derive 52,374 expressed sequence tags from pre- and peri-implantation embryos, embryonic day (E) 12.5 female gonad/mesonephros, and newborn ovary. From these cDNA collections, a microarray representing 15,264 unique genes (78% novel and 22% known) was assembled. In initial applications, the divergence of placental and embryonic gene expression profiles was assessed. At stage E12.5 of development, based on triplicate experiments, 720 genes (6.5%) displayed statistically significant differences in expression between placenta and embryo. Among 289 more highly expressed in placenta, 61 placenta-specific genes encoded, for example, a novel prolactin-like protein. The number of genes highly expressed (and frequently specific) for placenta has thereby been increased 5-fold over the total previously reported, illustrating the potential of the microarrays for tissue-specific gene discovery and analysis of mammalian developmental programs.

Abstract
We examined the effects of systemic administration of monosodium glutamate (MSG) or aspartate (ASP) on the memory retention and neuronal damage in the brains of adult mice. Compared with the control mice, a single intraperitoneal injection of either 4.0 mg/g MSG or 0.5 mg/g ASP after acquisition trial significantly shortened the response latency in the passive avoidance test, accompanying by the transient weight loss. Histopathological analysis of the brains of these mice revealed that neurons in the arcuate nucleus of hypothalamus were damaged markedly by MSG (4.0 mg/g) or ASP (0.5 mg/g). Other brain areas including cerebral cortex and hippocampus did not show any pathological changes. These findings suggest that systemic administration of MSG or ASP could impair memory retention and damage hypothalamic neurons in adult mice.

Abstract
The water labyrinth test and determining lipid peroxide (LPO) contents were used to assay the effects of Codonopsis lanceolata on promoting intelligence development and lipid peroxide. The results showed that latent period of old mice in water labyrinth was statistically shorten and the number of mistake of old mice was visibly reduced by drinking extraction of Codonopsis lanceolate 4 g/kg and 8 g/kg. These indicated that mice drinking extraction of Codonopsis lanceloata learned faster that those of drinking water. The contents of LPO in red blood cell and brain of mice and rate drinking extraction of Codonopsis lanceolata were significantly reduced, the activities of superoxide dismutase (SOD) in serum of rat drinking extraction of Codonopsis lanceolata were visibly increased. These presents that the extraction of Codonopsis lanceolata has the role of promoting learning and memory of old animal, its mechanism might be increasing SOD activity and decreasing LPO level.

Abstract
This study examines the effect of the psychotropic drug minaprine on memory impairment in Mongolian gerbils subjected to a 5-min bilateral common carotid artery occlusion, as assessed by their performance in an 8-arm radial maze task. Gerbils were initially trained on the 8-arm radial maze until their mean error was 0-1 for 5 days. This task was repeated before the ischemia was performed and again 7 days after it. Then the animals were immediately sacrificed for histopathological examination. Severe memory impairment occurred in the control gerbils; whereas when minaprine 75 mg/kg was given orally 30 min before the 5-min occlusion, memory impairment was significantly reduced. Histopathological analysis of the control gerbils showed nearly complete loss of the pyramidal neurons in the CA1 region of the hippocampus, whereas the minaprine-treated gerbils showed complete preservation of the pyramidal neurons. These findings suggest that minaprine has memory-impairment-prevention and neuroprotective effects against short-term ischemia in gerbils.

Abstract
EDH17B2, the gene encoding 17 beta-hydroxysteroid dehydrogenase type 1, has been suggested as a candidate for the familial breast cancer gene, BRCA1, located on 17q12-q21. We analyzed the promoter region of EDH17B2 in DNA from 20 control individuals and 40 patients with familial breast cancer. Two frequent (designated vI and vIII) and two rare (vII and vIV) nucleotide variations were present in both the breast cancer patients and the controls, except the alteration vII, which was found only in one patient. Although the data do not support the identification of EDH17B2 as the BRCA1 gene, it is of interest that point mutation vIV (A-->C) was located in the putative TATA box of the EDH17B2 gene. Reporter gene analyses showed that the mutation vIV decreases EDH17B2 promoter activity by an average of 45% in in vitro assays, suggesting that nucleotide A at position -27 is significant for efficient transcription.

Abstract
An Arg91Gln substitution in the mature von Willebrand factor (vWF) has been associated with defective binding of vWF to factor VIII (FVIII). We studied four families with members initially classified as having type I von Willebrand disease (vWD) who were either homozygous or heterozygous for the Arg91Gln change. The first family was the original case described by Nishino et al. (1) where three members were homozygous for the Gln91 allele. They had a low FVIII coagulant activity:vWF antigen (VIIIC:vWFAg) ratio, from 0.29 to 0.44, and the ability of their plasma vWF to bind FVIII was markedly decreased. All the heterozygous members had normal vWF and FVIII levels but the capacity of their plasma vWF to bind FVIII was reduced and intermediate between the homozygous members and normals. The affected individual from the second family was heterozygous for the Gln91 allele and demonstrated a VIIIC:vWFAg ratio of 0.98. The FVIII binding assay confirmed the heterozygous status indicating that the moderately low levels of vWF were due to reduced expression of both alleles. The propositus from the third family was also heterozygous and had below normal levels of vWF as well as a low VIIIC:vWFAg ratio of 0.34; however, FVIII binding to her plasma vWF was similar to that of the homozygous individuals suggesting that Gln91-vWF was the major circulating form. Her daughter who has type I vWD inherited the allele without the Gln91 mutation indicating that the expression of this allele was indeed impaired. The heterozygous patient in the fourth family had a vWF level of 24 U/dl but an VIIIC:vWFAg ratio greater than 2.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
Oligonucleotides were computer designed to amplify by the polymerase chain reaction (PCR) the coding region, splice junctions, 112 bp of the 5' flanking region and 279 bp surrounding the polyadenylation site of the factor IX gene for analysis by denaturing gradient gel electrophoresis (DGGE). Forty-four unselected haemophilia B patients were studied of whom 24 had severe haemophilia and 20 had a mild to moderate form of the disease. Potential mutations were identified in 40 (91%) of the 44 cases. A defect could not be detected in three severe and one mild haemophiliac by DGGE analysis and direct sequencing of all the PCR fragments from these patients revealed no nucleotide alteration supporting the DGGE results. A total of 37 point mutations, two complete gene deletions and a duplication of 26 bp were found. The 37 point mutations included 35 single nucleotide substitutions, a deletion and an insertion of one nucleotide. The 35 single nucleotide substitutions included 26 missense mutations, seven nonsense mutations, a G (-6) to A transition in the promoter region and a G (30154) to A transition within the donor splice site of the last intron. Fifteen of these nucleotide substitutions involved CpG dinucleotides. Fifteen point mutations were found at codons where nucleotide substitutions had not been detected before. An insertion of a single nucleotide T at position 6370 and deletion of a G at nucleotide 30845 resulted in frameshift mutations creating stop codons at amino acid positions -2 and 250, respectively. A duplication of 26 bp (17747-17772) in exon V was found in a severe haemophilia patient resulting in a termination codon in exon VI. The detection of the mutation by the combined use of PCR, DGGE and direct sequencing was important for carrier diagnosis of 20 families with no prior history of haemophilia B.
