       FIELD OF THE INVENTION 
       [0003]    The present invention relates to genes of Javanese medaka ( Oryzias Javanicus ) differentially regulated upon exposure to endocrine-disrupting chemicals and methods using the same for diagnosing environmental pollution of hydroecosystem. 
       BACKGROUND OF THE INVENTION 
       [0004]    Endocrine disrupting chemicals (EDC) or endocrine disruptors (ED) are the chemicals that interfere with hormone system of a living organism exposed thereto. The EDs include dioxin, PCB, PAH, furan, or phenol, for example. 
         [0005]    Among these, 17β-estradiol (E2) is known as one of the strongest estrogen-family steroid hormone (estrone (E1), 17β-estradiol and estriol (E3)). In humans, E2 is prevalently formed in the ovaries and placentas of women of childbearing age, but also observed in fat tissues of men or menopausal women. 17β-estradiol in synthesized form is used for regulating a variety of menopause-associated symptoms such as vasomotor dysfunction, vulvar and vaginal contraction disorders, and osteoporosis. Estron and estriol including 17β-estradiol released from humans and animals are distributed to environment via sewage treatment plants or animal waste. Accordingly, the safety of ecosystem is threatened by the exposures to the steroid hormones. For example, the hormones induce vitellogenin synthesis and feminization of male fish, which can possibly affect normal endocrine functions and male fertility and subsequently disturb ecosystem. Accordingly, a method is necessary, which can estimate presence/absence of 17β-estradiol, predict biological changes due to exposure thereto, and make early diagnosis. 
         [0006]    Bisphenol A (BPA) is another example of EDs. BPA has been widely used for the manufacture of plastic products since 1950, and also used for the manufacture of epoxy resin which is applied on inner sides of food cans. Food preserved in BPA containers is the major route of human health exposure to BPA. The general understanding is that the amount of BPA release particularly increases when the container surface becomes damaged or heated. BPA is directly distributed by sewage water from the plastic manufacturing factories or domestic sewage, or leaches from the plastic garbage disposed in environment. 
         [0007]    Exposure to BPA is understood to cause adverse effects on growth, reproductive health and development of aquatic organisms. Endocrine disruption effect was observed in invertebrates, fish, amphibians and reptiles at actual concentrations of environment without acute toxicity. Researches in Canada revealed that certain fish groups in non-contaminated water system had 55% females, whereas the female proportion was 85% in the water system that is contaminated with EDs including BPA. The above suggests that EDs destruct biological population ratio, thus causing severe disruption in ecosystem. Along with estrogen, BPA is known as an ED of living organisms, which impedes generation and development, and induces attention deficit hyperactivity disorder due to disturbance of nervous system, deformity, and abnormal gene expression due to inhibited DNA methylation. The chemical is also reported to stimulate development of a variety of cancerous cells. In September, 2010, Canada declared, for the first time, BPA on the toxic substance list and the chemical is currently banned for use in infant feeding bottles in the European Union (EU) and Canada. It is thus necessary to develop a method, with which it is possible to determine presence/absence of BPA in hydroecosystem, estimate biological changes from exposure to the chemical, and make early diagnosis. 
         [0008]    Living organisms have developed biological defense mechanisms to maintain homeostasis in response to changing external factors such as pollutions, atmosphere or infection with pathogenic microorganisms. The biological defense mechanisms involve actively changing expression levels of specific genes and regulating amounts of specific proteins. This suggests that, by investigating the genes that are specific to certain changes and monitoring their expression levels, it will be possible to obtain not only information about environmental changes of a specific area, but also information about the influence that such environment changes can have on phenomenon of life and health of ecosystem. 
         [0009]    To be specific, the Javanese medaka ( oryzias javanicus ) (Inoue and Takei, Zoological Sci., 19, 727-734, 2002), which is highly adaptable to all levels of salinities (i.e., to both fresh water and seawater), is expected to be applicable for the researches on environmental risk assessment by chemical pollutants. The following researches have been conducted on changes in proteins and gene expressions of Javanese medaka in response to toxic chemicals: research on fertility and vitellogenin protein concentration variations of male Javanese medaka liver tissues exposed to 17β estradiol (E2) (Imai et al., Mar. Poll. Bull., 51, 708-714, 2005); research on choriogenin H and L gene expression level differences in male Javanese medaka liver tissues in response to exposure to E2 (Yu et al., Aquat. Toxicol., 77, 348-358, 2006); research on metallothionein gene expression level differences in Javanese medaka liver tissues in response to exposure to a variety of heavy metals (Woo et al., Mar. Biotech., 8, 654-662, 2006); research on fertility and vitellogenin protein concentration differences in Javanese medaka liver tissues in response to exposure to estrone (E1) in environment (Imai et al., Environ. Toxicol. Chem., 26, 726-731, 2007). Additional researches reported expression level differences of antioxidant enzymes and stress-associated genes in response to exposure to six major heavy metals (Ag, Cd, Cr, Cu, Ni, Zn) (Woo et al., Comp. Biochem. Physiol. C, 149, 289-299, 2009); organophosphorus pesticides (Iprobenfos) (Woo et al., Comp. Biochem. Physiol. C, 149, 427-432, 2009); and polychlorinated camphene (Toxaphene) (Woo et al., Comp. Biochem. Physiol. C, 153, 355-361, 2011). However, none has confirmed gene expression differences of Javanese medaka in response to exposure to 17β-estradiol or BPA, to use this as a biomarker to detect possible exposure to EDC, i.e., 17β-estradiol or BPA. 
         [0010]    The present inventors have investigated biomarkers that react to marine environmental pollution such as exposure to EDCs with Javanese medaka by, specifically, investigating biomarkers that can confirm possible exposure to 17β-estradiol and expression level differences of these gene biomarkers, and also investigating biomarkers that can confirm possible exposure to BPA and expression level differences of these gene biomarkers, and as a result, completed the present invention based on the confirmation that the biomarkers can be applied for the diagnosis of environmental pollution in hydroecosystem.

         [0036]    To explore genes of  Oryzias javanicus  differentially regulated upon exposure to 17β-estradiol,  Oryzias javanicus  was exposed to 17β-estradiol in a concentration of 100 μg/L for 24 or 48 hour and then cDNAs were synthesized and genes showing changed expressions were investigated. Specifically, cDNAs were synthesized from mRNAs extracted from Javanese medaka ( Oryzias javanicus ) reared in seawater of the absence or presence of 17β-estradiol. PCR was performed to amplify fragments of genes of which expressions were changed. As the result, 56 genes of which expressions were increased or decreased were selected (Refer to table 1 or table 2). Steroid hormones of estrogen series like 17β-estradiol result in the disturbance of ecosystem, impairing the normal endocrine function and the followed sexual function which are attributable to the synthesis of vitellogenin and feminization in males. Therefore, there can be investigated stress and health of marine organisms according to alterations of external environment by analyzing expression profiles of genes causing physiological and metabolic changes. Also, those genes can be exploited as biomarkers for diagnosing health of living things and the environment. 
         [0037]    Therefore, for detecting stress and diagnosing conditions resulting from pollution by persistent toxic substances like 17β-estradiol, said gene can be usefully exploited as biomarkers and in a microarray chip since expression of said gene showed significant difference upon exposure to 17β-estradiol. 
         [0038]    The present invention also provides a method for detecting exposure to 17β-estradiol and diagnosing environmental pollution, said method comprising the steps of:

         [0045]    For the microarray chip of step 4) in said method, any microarray chip can be used if it contains said gene. Above procedures are preferably performed according to conventional experimental protocols of microarray chip but not limited thereto: 
         [0046]    The present invention also provides a method for detecting exposure to 17β-estradiol (E2) and diagnosing environmental pollution, said method comprising the steps of: 
         [0047]    1) separating RNAs from  Oryzias Javanicus  of a sample of an experimental group exposed to a specimen (17β-estradiol), and from  Oryzias Javanicus  of a control group; 
         [0048]    2) performing real time RT-PCR with the RNAs of step b) using a primer pair complementary to said gene to amplify it; and 
         [0049]    3) comparing gene expression levels between the experimental group and the control group as measured by real-time RT-PCR in step 2). 
         [0050]    For a primer pair of step 2) in said method, any primer pair can be used if it is complementary to a selected gene and can amplify said gene. 
         [0051]    The present inventors found that they can diagnose environmental conditions caused by exposure to 17β-estradiol through the use of said gene, uncovering 56 genes of which expressions are increased or decreased in response to exposure to 17β-estradiol. Therefore, in the present invention genes differentially regulated upon exposure 17β-estradiol can be usefully exploited for said microarray chip as well as a stress detection and a diagnosis of environmental pollution using real-time RT-PCR. 
         [0052]    The present invention also provides a kit comprising said microarray chip for detecting exposure to 17β-estradiol and diagnosing environmental pollution.

         [0092]    In a specific example of the present invention, to identify genes of Javanese medaka differentially regulated upon exposure to BPA, Javanese medakas were exposed to 76 μg/L BPA for 48 hr in each seawater and general seawater condition. Then, mRNAs were extracted from them and cDNAs were synthesized. Finally, differentially regulated genes were investigated by using microarray. In the result, 96 genes of which expressions were changed upon exposure to Bisphenol A were found (Refer to table 5). Total 28 genes which are involved in defense mechanisms against external stress were selected and primers for them were designed and synthesized for quantitative real-time reverse transcript polymerase chain reaction (qRT-PCR: Refer to table 6). qRT-PCR was performed using synthesized primers, followed by the investigation of differentially regulated genes (Refer to table 7).

       MODE FOR INVENTION 
       [0096]    The present invention will be explained in detail with reference to the examples below. However, the following examples are offered for purpose of illustration, not limitation. 
       Example 1 
     Culturing Javanese Medaka and Exposure to Endocrine Disruption Chemical 17β-Estradiol (E2) or Bisphenol A (BPA) 
       [0097]    &lt;1-1&gt; Culturing Javanese Medaka 
         [0098]    Javanese medaka was cultured in natural seawater filtered through three types of filters (10, 10 and 1 μm). Water temperature was fixed at 25° C. with underwater heater, and  Artemia salina  nauplii were fed once a day. 
         [0099]    &lt;1-2&gt; Exposure to 17β-Estradiol or BPA 
         [0100]    To 3 L beaker with 2 L filtered seawater therein, 10 male Javanese medaka bred in culture water tank were transported each time, and acclimated for 24 hr. Five male Javanese medaka of Example &lt;1-1&gt; were exposed to 17β-estradiol (100 μg/L) for 24 hr and 48 hr, respectively. Additionally, five Javanese medaka of Example &lt;1-1&gt; were exposed to BPA (76 μg/L) for 48 hr. The concentration of exposure was set to a relatively very low level so that it was 1/100 the BPA lethal concentration 50 (LC50) of  Oryzias latipes . The Javanese medaka was transported to ice water, one at a time, which momentarily stunned it, followed by beheading and evisceration and liver removal. 
       Example 2 
     Measuring Gene Change in Response to Exposure to 17β-Estradiol 
       [0101]    &lt;2-1&gt; Isolating RNA 
         [0102]    To the Javanese medaka livers of 17β-estradiol exposed group (24 hr &amp; 48 hr) produced from Example &lt;1-2&gt;, and of control group without exposure, 1 ml of TRI Reagent solution (Molecular Research Center Inc, Cincinnati, Ohio, USA) was added, homogenized with glass homogenizer, and left at room temperature for 5 min. Next, chloroform (200 μl) was added and mixed, left at room temperature for 10 min. After centrifugation for 15 min (12,000×g, 4° C.), supernatant was obtained, to which isopropanol (500 μl) was added and left at room temperature for 5 min. After centrifugation for about 20 min (12,000×g, 4° C.), solution was removed, thus leaving precipitate. To the precipitate, 70% ethanol solution (50 μl) was added and after centrifugation for 5 min, ethanol solution was removed, and the precipitate RNA was dried. After drying, the product was dissolved in appropriate amount of DEPC (diethylpyrocarbonate)-treated water. 
         [0103]    &lt;2-2&gt; Cy3 and Cy5 Labeling 
         [0104]    The entire RNA of the distilled exposed group and non-exposed group were labeled with Cy3 and Cy5 as follows, using Agilent&#39;s Low RNA Input Linear Amplification Kit Plus (Agilent Technologies, USA). To be specific, RNA (1 μg) was mixed with dT-promoter primer and MMLV-Reverse transcriptase. After reverse transcription at 40° C. for 2 hr, T7 polymerase was added, and linear amplification was done at 40° C. for 2 hr. After the amplification process explained above, the samples of experimental and control groups were labeled with Cy3-CTP and Cy5-CTP, respectively. 
         [0105]    &lt;2-3&gt; Hybridization and Scanning 
         [0106]    Fluorescent-labeled cDNA sample was purified with Qiagen PCR purification kit, and eluted with distilled water. The purified, fluorescent-labeled cDNA sample was added to hybridization buffer (3×SSC, 0.3% SDS, 50% formamide, 20 μg Cot-1 DNA, 20 μg yeast tRNA), and concentrated with microcon YM-30. After hybridization, the hybridized compound was heated at 95° C. for 3 min for denaturalization, and the temperature of the heated, hybridized compound was decreased by centrifugation for 30 sec at 12,000 g. The produced Javanese medaka cDNA microarray was covered with coverslip, and the denaturalized, hybridized compound was pipetted. The microarray was put into GT-Hyb chamber for reaction to occur at 65° C. for 16 hr. After hybridization, the microarray was taken out of the chamber, underwent cleansing process as explained below, rotated and dried, and stored in a dark room until scanning. The Javanese medaka microarray was then scanned with Axon GenePix 4000B scanner (Axon Instrument, USA). On the GenePix Pro 6.0 program, dots from the scanned image were gridded using gridding file, and quantified to produce GPR file including analysis on cy5/Cy3 magnitudes and ratios. 
         [0107]    &lt;2-4&gt; Microarray Data Analysis 
         [0108]    Based on the GPR file obtained with the GenePix Pro Program, the following analysis was made using analysis program, i.e., GeneSpring 7.3.1 (Agilent Technologies, USA). Normalization: by LOWESS (locally weighted regression scatterplot smoothing). Reliable gene): significant genes were obtained by flagging out dots whose sums of medial values were less than the background, or dots whose standard deviations of pixel values are not significant. Significant genes: dots whose normalized ratio is at 10 times higher interval, were screened. 
         [0109]    The result confirmed that exposure to 17β-estradiol for 24 hr (Table 1) and 48 hr (Table 2) caused increase or decrease of gene expression levels compared to the control by two or more times higher or lower, in which 52 species with 10 times or higher expression differences were identified with SEQ ID. NOs. 1 to 52 and the following nucleic acid sequences.

     Quantification of Expression Differences of Genes Screened as Having Expression Differences after Exposure to 17β-Estradiol 
       [0110]    &lt;3-1&gt; Screening Genes Involved with Self Defense Mechanisms to External Stress 
         [0111]    Among Javanese medaka genes having two or more times greater expression differences after exposure to 17β-estradiol in Example &lt;2-4&gt;, total seven genes were screened, as having high involvement with the self defense mechanisms to external stress, which are: 
         [0112]    Apolipoprotein B, P450 1A (Cytochrome P450 1A, CYP1A), glutamate dehydrogenase 1b, glucose-6-phosphate dehydrogenase, transferrin, vitellogenin 1 and selenoprotein M. 
         [0113]    Primers for real-time quantitative PCR (RT-PCR) for the above genes were designed and synthesized (Table 3). The expression differences of the above-listed genes were analyzed with reference to Javanese medaka livers exposed to 17β-estradiol for 48 hr.

     Measuring Changes in Genes in Response to Exposure to BPA 
       [0119]    &lt;4-1&gt; Isolation of RNA 
         [0120]    To the Javanese medaka livers of BPA exposed group (48 hr) produced from Example &lt;1-2&gt;, and of control group without exposure, 1 ml of TRI Reagent solution (Molecular Research Center Inc, Cincinnati, Ohio, USA) was added, homogenized with glass homogenizer, and left at room temperature for 5 min. Next, chloroform (200 μl) was added and mixed, left at room temperature for 10 min. After centrifugation for 15 min (12,000×g, 4° C.), supernatant was obtained, to which isopropanol (500 μl) was added and left at room temperature for 5 min. After centrifugation for about 20 min (12,000×g, 4° C.), solution was removed, thus leaving precipitate. To the precipitate, 70% ethanol solution (50 μl) was added and after centrifugation for 5 min, ethanol solution was removed, and the precipitate RNA was dried. After drying, the product was dissolved in appropriate amount of DEPC (diethylpyrocarbonate)-treated water. 
         [0121]    &lt;4-2&gt; Cy3 and Cy5 Labeling 
         [0122]    The entire RNA of the distilled exposed group and non-exposed group were labeled with Cy3 and Cy5 as follows, using Agilent&#39;s Low RNA Input Linear Amplification Kit Plus (Agilent Technologies, USA). To be specific, RNA (1 μg) was mixed with dT-promoter primer and MMLV-Reverse transcriptase. After reverse transcription at 40° C. for 2 hr, T7 polymerase was added, and linear amplification was done at 40° C. for 2 hr. After the amplification process explained above, the samples of experimental and control groups were labeled with Cy3-CTP and Cy5-CTP, respectively. 
         [0123]    &lt;4-3&gt; Hybridization and Scanning 
         [0124]    Fluorescent-labeled cDNA sample was purified with Qiagen PCR purification kit, and eluted with distilled water. The purified, fluorescent-labeled cDNA sample was added to hybridization buffer (3×SSC, 0.3% SDS, 50% formamide, 20 μg Cot-1 DNA, 20 μg yeast tRNA), and concentrated with microcon YM-30. After hybridization, the hybridized compound was heated at 95° C. for 3 min for denaturization, and the temperature of the heated, hybridized compound was decreased by centrifugation for 30 sec at 12,000 g. The produced Javanese medaka cDNA microarray was covered with coverslip, and the denaturized, hybridized compound was pipetted. The microarray was put into GT-Hyb chamber for reaction to occur at 65° C. for 16 hr. After hybridization, the microarray was taken out of the chamber, underwent cleansing process as explained below, rotated and dried, and stored in a dark room until scanning. The Javanese medaka microarray was then scanned with Axon GenePix 4000B scanner (Axon Instrument, USA). On the GenePix Pro 6.0 program, dots from the scanned image were gridded using gridding file, and quantified to produce GPR file including analysis on cy5/Cy3 magnitudes and ratios. 
         [0125]    &lt;4-4&gt; Microarray Data Analysis 
         [0126]    Based on the GPR file obtained with the GenePix Pro Program, the following analysis was made using analysis program, i.e., GeneSpring 7.3.1 (Agilent Technologies, USA). Normalization: by LOWESS (locally weighted regression scatterplot smoothing). Reliable gene): significant genes were obtained by flagging out dots whose sums of medial values were less than the background, or dots whose standard deviations of pixel values are not significant. Significant genes: dots whose normalized ratio is at 10 times higher interval, were screened. 
         [0127]    The measurement of gene change in response to exposure to BPA for 48 hr caused increase or decrease of gene expression levels compared to the control by two or more times higher or lower, in which 92 species with 2 times or higher expression levels were identified with SEQ ID. NOs. 71 to 162 (Table 5).

         [0133]    With RNA template extracted with the method of Example &lt;2-1&gt;, cDNA was synthesized using AB High Capacity RAN-to-cDNA Kit (Applied Biosystems, USA). RNA in the amount of 1 μg was seeded, added with distilled water and titrated to 9 μl. 2×RT buffer (10 μl), and 20× enzyme Mix 1 μl were mixed well, centrifuged and precipitated, and allowed to react at 37° C. for 60 min. The reactant was heated at 95° C. for 5 min, after which reaction was completed. The synthesized cDNA was stored at −20° C. 
         [0134]    &lt;5-3&gt; Real-Time Quantitative PCR 
         [0135]    To the 0.5 μg synthesized cDNA (corresponding to approximately 10 ng/μl), 0.8 primer pairs of corresponding genes (10 pmol/μl), and 2 SYBR1 mixture (10 μl) were added. The final amount was titrated to 20 μl using distilled water. At temperature condition of 95° C. 10 min, 95° C. 30 sec, 60° C. 30 sec, 72° C. 30 sec, 40 cycles of PCR were conducted. 
         [0136]    CT values of the respective samples after exposure to BPA between control genes (β-actin) and genes of interest were compared with each other, and the relative expression differences of the genes of interest were quantified into relative values according to Relative Standard Curve (Table 7).

       INDUSTRIAL AVAILABILITY 
       [0137]    The Javanese medaka genes that react to exposure to one of the endocrine disruption chemicals, i.e., 17β-estradiol, or Javanese medaka that react to exposure to BPA can be advantageously used as a biosensor component to monitor and diagnose EDC contamination of hydroecosystem. Furthermore, considering ability to specify physiological changes in metabolism of living organisms based on the functions of the presented genes, use as biomarker and sensor is applicable to predict pathological phenomena that can occur, and also effective use for the detection of stress sources of hydroecosystem or health condition diagnosis is provided.
