Hatano high (HAA)- and low (LAA)-avoidance rats were selected from Sprague-Dawley rats
genetically on the basis of their active avoidance behavior in a shuttle-box test. The purpose of thisstudy was to investigate stress-related alterations of hormones corticotropin-releasing hormone(CRH), arginine-vasopressin (AVP), prolactin, and adrenocorticotropin (ACTH) in the brain
and blood during early avoidance acquisition using two lines of Hatano rats. In paraventricular
nucleus (PVN) of the hypothalamus, the CRH levels in HAA rats were significantly increased
after shuttle-box tasks compared with before the tasks, whereas the CRH levels in LAA rats
60

significantly decreased after shuttle-box tasks compared with before the tasks. In the HAA rats,
the CRH and AVP levels in the median eminence decreased after shuttle-box tasks, whereas there
were no significant differences in the levels between before and after shuttle-box tasks in LAA rats.
The plasma concentrations of ACTH were significantly higher in HAA rats than in LAA rats after
shuttle-box tasks. These results show that the response of CRH-ACTH was higher in HAA rats thanin LAA rats. This phenotype may be an important reason for the high avoidance rates of shuttle-box
tasks in HAA rats. These endocrine differences in early avoidance acquisition may be involved inregulation of their avoidance responses in the shuttle-box task.

The embryonic stem cell test (EST) is an in vitro assay that has been developed to assess theembryotoxic potential of chemicals and biomaterials. An attempt for improvement in that ES cells
used in the EST protocol are restricted to ES-D 3 cells. If other kinds of ES cell become available,
its experimental application will be further usefulness. We compared the incidence of pulsation
between ES-D3 cells requiring no feeder cells for cultivation and EL M3 cells or ES-R 1-EGFP B 2 /EGFP cells requiring feeder cells, to explore the experimental possibility of using ES cells requiring
feeder cells.

秦野研究所年報 Vol. 35. 2012

As the present results with ES-D 3 and EL M3 cells were similar to those obtained under the twodimensional condition, these two kinds of cell are thought to be equally available under the present
three-dimensional conditions. On the other hand, because ES-R1-EGFP B2/EGFP cells did not show
any pulsation at all in the three-dimensional culture, other experimental conditions for the threedimensional culture method need to be established with those cells. Besides, it was suggested thatsimilar results could be obtained with EL M 3 cells requiring feeder cells for cultivation compared tothose with ES-D3 cells.

The Bhas 42 cell transformation assay is a sensitive short-term system for predicting chemical
carcinogenicity. Bhas 42 cells were established from BALB/c 3 T3 cells by the transfection of v-Haras gene and postulated to have acquired an initiated state in the two-stage carcinogenesis theory.
The Bhas 42 cell transformation assay is capable of detecting both tumor-initiating and tumorpromoting activities of chemical carcinogens. The full assay protocol consists of two components, theinitiation assay and the promotion assay, to detect the initiating activity and the promoting activity,
respectively. An international study was carried out to validate this cell transformation assay inwhich six laboratories from three countries participated. Twelve coded chemicals were examined
in total and each chemical was tested by three laboratories. In the initiation assay, concordantresults were obtained by three laboratories for eight out of ten chemicals and in the promotion
assay, concordant results were achieved for ten of twelve chemicals. The positive results wereobtained in all three laboratories with the following chemicals: 2 -acetylaminoﬂuorene was positivein both initiation and promotion assays; dibenz[a,h]anthracene was positive in the initiation assay;
sodium arsenite, lithocholic acid, cadmium chloride, mezerein and methapyrilene hydrochloride
were positive in the promotion assay. o-Toluidine hydrochloride was positive in the both assays in
62

研究業績

two of the three laboratories. D-Mannitol, caffeine and L-ascorbic acid were negative in both assays
in all the laboratories, and anthracene was negative in both assays in two of the three laboratories
except one laboratory obtaining positive result in the promotion assay. Consequently, the Bhas 42
cell transformation assay correctly discriminated all six carcinogens and two tumor promoters fromfour non-carcinogens. Thus, the present study demonstrated that the Bhas 42 cell transformation
assay is transferable and reproducible between laboratories and applicable to the prediction ofchemical carcinogenicity. In addition, by comparison of the present results with intra-laboratory
data previously published, within-laboratory reproducibility using the Bhas 42 cell transformation
assay was also confirmed.

Cell transformation assays (CTAs) have long been proposed as in vitro methods for theidentification of potential chemical carcinogens. Despite showing good correlation with rodent
bioassay data, concerns over the subjective nature of using morphological criteria for identifying
transformed cells and a lack of understanding of the mechanistic basis of the assays has limited
their acceptance for regulatory purposes. However, recent drivers to find alternative carcinogenicity
assessment methodologies, such as the Seventh Amendment to the EU Cosmetics Directive, havefuelled renewed interest in CTAs. Research is currently ongoing to improve the objectivity of theassays, reveal the underlying molecular changes leading to transformation and explore the use ofnovel cell types. The UK NC 3 Rs held an international workshop in November 2010 to review thecurrent state of the art in this field and provide directions for future research. This paper outlines
the key points highlighted at this meeting.

The aim of the present study was to evaluate both sensitivity and specificity of an in vivo skincomet assay using chemically treated, hairless mouse dorsal skin as a model. N-methyl-N'-nitroN-nitrosoguanidine (MNNG, 0 . 0125 – 0 . 2 %), 4 -nitroquinoline- 1 -oxide ( 4 NQO, 0 . 01 – 0 . 25 %),mitomycin C (MMC, 0 .0125– 0 .05%), benzo[a]pyrene (B[a]P, 0 . 25 –2 %), and 7, 12 -dimethylbenz[a]anthracene (DMBA, 0. 25–1 %) were each applied once to the dorsal skin of hairless male mice; after
3 h, epidermal skin cells were isolated, and the alkaline comet assay was performed. The assay was
performed after 24 h for only the B[a]P and DMBA. Furthermore, B[a]P and DMBA were evaluatedby alkaline comet assay using liver cells after both 3 and 24 h.
The mean percent of DNA (%DNA) in tail in the 0 . 05 – 0 . 2 % MNNG and 0 . 1 – 0 . 25 % 4 NQO
treatment groups was markedly higher than in the control group at 3 h post-application. Although
the mean %DNA values in the tail in the B[a]P and DMBA groups were the same as the controls at
3 h post-application, the 2% B[a]P and 1 % DMBA groups showed significantly higher values versus
controls 24 h after application. No significant increases in the mean %DNA in the tail were observedin the MMC group. No clear increases in %DNA in the tail were observed in the B[a]P and DMBA
groups at 3 or 24 h after application in the liver.
These results suggest that the in vivo skin comet assay is able to accurately identify DNAdamaging potential with a skin-specific response and is a useful method to detect the DNAdamaging potential of genotoxic chemicals on the skin.

We have already found that the in vivo skin comet assay is useful for the evaluation of primary
DNA damage induced by genotoxic chemicals in epidermal skin cells. The aim of the present study
was to evaluate the sensitivity and specificity of the combined in vivo skin comet assay and invivo skin micronucleus (MN) test using the same animal to explore the usefulness of the new test
method.
The combined alkaline comet assay and MN test was carried out with three chemicals:
4 -nitroquinoline- 1 -oxide ( 4 NQO), N-methyl-N'-nitro-N-nitrosoguanidine (MNNG) and benzo[a]pyrene (B[a]P). In the first experiment, we compared DNA- and chromosome-damaging effects of 3
[ 72, 24 and 3 hours (h) before sacrifice] and 4 applications ( 72, 48 , 24 and 3 h before sacrifice) of
4NQO, which induces dermal irritancy. The animals were euthanized and their skin was sampled
64

研究業績

for the combination test. As a result, the 4 -application method was able to detect both DNA- andchromosome-damaging potential with a lower concentration; therefore, in the second experiment,
MNNG and B[a]P were topically applied four times, respectively. The animals were euthanized,
and then their skins were sampled for combination tests. In the alkaline comet assay, significant
differences in the percent of DNA (%DNA) in the tail were observed in epidermal skin cells treatedwith MNNG and B[a]P. In the MN test, an increased frequency of MN cells (%MN) cells wasobserved by treatment with MNNG; however, there were no significant increases. In contrast,
significant differences in %MN were observed by treatment with B[a]P.
From these results, we conclude that the combined in vivo skin comet assay and in vivo MN test
was useful because it can detect different genotoxicity with the same sampling time and reduce thenumber of animals used.

The transgenic rodent (TGR) assay has been widely used to study in vivo gene mutations
by chemicals or radiation; however, an optimal protocol has not yet been established to assess
unknown genotoxic potential. The International Workshop on Genotoxicity Testing (IWGT) strongly
recommends a repeated-dose regimen for the TGR assay protocol for regulatory safety assessment asfollows: a treatment period of 28 days and a sampling time of 3 days following the final treatment.
In this study, TGR assays using F344 gpt delta transgenic rats were conducted at three laboratories
to evaluate the validity of the IWGT protocol, as part of a collaborative study of the transgenic rat
mutation assay. Male F 344 gpt delta transgenic rats were orally treated with 2, 4 -diaminotoluene( 2 , 4 -DAT; hepatic carcinogen in rodents; 10 and 30 mg/kg/day) or 2 , 6 -diaminotoluene ( 2 , 6 -DAT;
non-carcinogen in rodents; 60 mg/kg/day) once daily for 28 days. Rats were euthanized 3 days after
the last dosing, and then mutant frequencies (MFs) of the gpt gene in the livers were studied. As
a result, a significant increase in the MF was observed at 30 mg/kg in the 2, 4-DAT-treated group,
but not in the 2 , 6 -DAT-treated group. These results were commonly observed among the threelaboratories. In addition, the overall results from the three laboratories were in general agreement.
These results indicate that 2 ,4 -DAT induces gene mutation in the liver of gpt delta rats, but 2 , 6 DAT does not. These results also indicate that the F 344 gpt delta transgenic rat mutation assay
can distinguish differences in the in vivo mutagenic potential between a hepatic carcinogen and a
non-carcinogen. Results from one laboratory showed more variability than those from the other twolaboratories, and this appearance was due to the smaller number of colonies scored. Thus, theseresults demonstrate that the IWGT protocol for the TGR assays is valid, and show that consistent
results are obtained among different laboratories.

In the present study, in order to reveal novel adverse effects of ultrafine particles (UFP) on thecentral nervous system, the effects of nanoparticle-rich diesel exhaust particles (NRDEP; countmode diameter, 21 . 45 nm) on emotional behavior, learning capability and brain neurotransmitterlevels were studied in rats by intranasal instillation (iNI). NRDEP ( 10 and 50 µg/rat) was instilled
into 2 -week old infant, male rats once a week for 4 weeks. Spontaneous motor activity measured
was observed to be inverse to the dose level. In active avoidance tests using a shuttle box, NRDEPtreated animals showed a lower avoidance performance than control animals given air-instillation.
The levels of dopamine and its metabolite (DOPAC) in the medial mammillary nucleus of the brain
tended to be lower in the NRDEP-treated animals. From these results, although the effects of
NRDEP by iNI on the emotionality and the brain neurotransmitter levels were not fully clear, theresults obtained by avoidance testing suggested involvement of UFP in learning capability.

Effects of the genotoxic agent 5-bromo-2'-deoxyuridine with or without pre-pubertal
gonadectomy on brain monoamines and their metabolites in female rats
Makiko KUWAGATA, Katsumasa MUNEOKA1, Tetsuo OGAWA1, Seiji SHIODA1
Brain Research Bulletin, 2011 ; 85 ( 3 - 4 ): 207 - 211
A nucleotide analog 5 -bromo- 2 ′-deoxyuridine (BrdU) is a genotoxic compound. Previous studies
have demonstrated that prenatal treatment of rodents with BrdU affects the development ofcortical neurons, reduces dopamine levels, and elevates serotonin ( 5 -HT) levels in the striatumin adult male offspring from BrdU-treated dams. Moreover, prenatal BrdU-treated rats show
locomotor hyperactivity in both males and females. This study investigated sexual dimorphism in
the effect of prenatal BrdU on monoamine metabolism. Sprague–Dawley rats were treated with
BrdU on gestational days 9 – 15 ( 50 mg/kg, i.p.) and monoamine metabolism was examined infemale rats at 10 weeks of age. The inﬂuence of pre-pubertal gonadectomy on the effects of BrdU
was also investigated. BrdU-treated females showed elevations of dopamine and 5 -HT levels inthe striatum; reductions in dopamine, dihydroxyphenylacetic acid, or homovanillic acid (HVA) inthe hypothalamus or the midbrain; and elevated HVA and 5 -HT in the hippocampus. Pre-pubertal
gonadectomy had a suppressive effect on striatal dopamine levels in prenatal BrdU-treated females.
The present data indicate sexual dimorphic effects of prenatal BrdU-treatment in striatal dopamine
metabolism but not in serotonergic metabolism and suggest a contribution of the increasing gonadal
hormones that accompany puberty to this sex difference.

Behavioral results are sometimes not reproducible even in the positive controls of developmental
neurotoxicity (DNT) tests. Effects of several factors on the results should be considered. In thepresent paper, we examined the effects of strain-, gender-, and test-condition differences on BrdU67

秦野研究所年報 Vol. 35. 2012induced hyperactivity. The results showed that BrdU-induced hyperactivity was reproducible intwo rat strains (SD and F344 rats), rodent species (rat and mouse), and both sexes. When the levelof background sound in a test room was increased, the hyperactivity was persistent, resulting in no
effect of background sound on BrdU-induced hyperactivity. Thus, we have demonstrated that the
BrdU-animal model is a useful positive control via prenatal exposure to validate the entire DNT test
process.

Hatano high- and low-avoidance rats (HAA and LAA strains, respectively) were selected and bredaccording to the avoidance rate in a shuttle-box task. Although they have clear strain differencesin ovarian function, their endocrine mechanisms still remain to be clarified. Differences infemale reproductive endocrinology between the strains were investigated by means of measuring
the plasma concentration of reproductive hormones during the estrous cycle. LAA rats showedapproximately threefold lower basal and surge levels of LH, a more than fourfold lower level of
FSH surges and higher levels of inhibin A and inhibin B during the estrous cycle compared withthe levels seen in HAA rats. The concentration of estradiol- 17 β in the proestrous stage wassignificantly lower in LAA rats than in HAA rats. Additionally, LH and FSH secretions fromprimary cultured anterior pituitary cells with or without in vitro GnRH stimulation were lower
in the cells derived from LAA rats and, in terms of FSH secretion, were unresponsive to GnRH incontrast to cells derived from HAA rats. Although an increased number of preantral follicles indiestrus were observed in LAA rats, number of hCG-induced ovulation was lower in LAA rats. LAA
rats may have much more follicle growth during the early stage of folliculogenesis, but most follicles
might not grow into mature follicles. These results strongly suggest that the strain difference inovarian function of these two Hatano rats is due to the difference in the regulation of hypothalamohypophyseal system for gonadotropins secretion.

A longevity gene product, Sir 2 (silent information regulator 2 ) is a NAD-dependent histone
deacetylase involved in longevity in yeasts, worms and flies. The mammalian homolog of Sir 2 ,SIRT1 (sirtuin 1 ), has been shown to play important roles related to anti-aging effects (regulating
apoptosis, stress tolerance, insulin resistance, and fat metabolism). Recently, SIRT1 expression has
been demonstrated to occur at as early as embryonic day 10 . 5 in mice. SIRT 1 during developing
period may be involved in the mechanism of developmental origins of adult diseases, such as
diabetes and cardiovascular disease. To investigate the contribution of SIRT 1 , it is important toreveal the distribution of this protein during development. In the present study, we demonstrated
the distribution of immunoreactivity of SIRT 1 in mouse organs during prenatal and neonatal
development by staining a wide variety of serial sections. The SIRT1 immunoreactivity was strongly
observed in the neuroepithelial layer, dorsal root ganglion, trigeminal ganglion, eyes, roots ofwhiskers, and internal organs, including the testis, liver, heart, kidney, and lung during the fetal
period. Neurons which had finished migrating still showed relatively strong immunoreactivity. The
immunoreactivity was completely absorbed by the blocking peptide in an absorption test. During
the postnatal period, the immunoreactivities in most of these organs, except the heart and testis
weakened, with the liver most dramatically affected. As SIRT 1 expression was demonstrated in awide variety of developing organs, further study to investigate prenatal factors which affect SIRT 1
expression and its activity is important.

The ovary is the main secretory source of progestin and estrogen and is indispensable to themaintenance of all events of pregnancy in mice. The purpose of this study was to control allprocesses of pregnancy in mice, from embryo implantation to parturition, without ovaries. The
ovaries were removed before embryo implantation, and a single injection of medroxyprogesterone
acetate (MPA) was given. Embryo implantation was induced by leukemia inhibitory factor, which
can substitute 17 β -estradiol (E 2 ). Continuous exposure to E 2 was necessary at mid-pregnancy,
when placentation was completed. All mice sustained pregnancy without ovaries before parturition,
which was initiated by the removal of E 2 and MPA. Murine pregnancy is a complicated process
involving embryo implantation, placentation, and parturition. Complete control of pregnancy wasachieved with the simple treatment of MPA and E 2 after induction of embryo implantation. Here,time-dependent events in the uterus during pregnancy could be realized without the ovaries,
because the initiation of each event could be stringently controlled by hormonal treatments.
