Rapid method for identification of transgenic fish zygosity Alimuddin, .; Yoshizaki, G.; Carman, O.
Jurnal Akuakultur Indonesia Vol. 6 No. 2 (2007): Jurnal Akuakultur Indonesia
Publisher : Indonesian Society of Scientific Aquaculture (ISSA)

Identification of zygosity in transgenik fish is normally achieved by PCR analysis with genomic DNA template extracted from the tissue of progenies which are derived by mating the transgenic fish and wild-type counterpart. This method needs relatively large amounts of fish material and is time- and labor-intensive. New approaches addressing this problem could be of great help for fish biotechnologists. In this experiment, we applied a quantitative real-time PCR (qr-PCR) method to analyze zygosity in a stable line of transgenic zebrafish (Danio rerio) carrying masu salmon, Oncorhynchus masou D6-desaturase-like gene. The qr-PCR was performed using iQ SYBR Green Supermix in the iCycler iQ Real-time PCR Detection System (Bio-Rad Laboratories, USA). Data were analyzed using the comparative cycle threshold method. The results demonstrated a clear-cut identification of all transgenic fish (n=20) classified as a homozygous or heterozygous. Mating of those fish with wild-type had revealed transgene transmission to the offspring following expected Mendelian laws. Thus, we found that the qTR-PCR to be effective for a rapid and precise determination of zygosity in transgenic fish. This technique could be useful in the establishment of breeding programs for mass transgenic fish production and in experiments in which zygosity effect could have a functional impact. Keywords: quantitative real-time PCR; zygosity; transgenic fish; mass production ABSTRAK Identifikasi sigositas ikan transgenik biasanya dilakukan menggunakan analisa PCR dengan cetakan DNA genomik yang diekstraksi dari jaringan ikan hasil persilangan antara ikan transgenik dan ikan normal. Metode ini memerlukan ikan dalam jumlah yang banyak, dan juga waktu serta tenaga. Pendekatan baru untuk mengatasi masalah tersebut akan memberikan manfaat besar kepada peneliti bioteknologi perikanan. Pada penelitian ini, kami menggunakan metode PCR real-time kuantitatif (krt-PCR) untuk menganalisa sigositas pada satu strain ikan zebra (Danio rerio) transgenik yang membawa gen D6-desaturase-like dari ikan salmon masu, Oncorhynchus masou. krt-PCR dilakukan menggunakan iQ SYBR Green Supermix pada mesin iCycler iQ Real-time PCR Detection system (Bio-Rad Laboratories, USA). Data dianalisis menggunakan metode pembandingan nilai cycle threshold. Hasil penelitian menunjukkan bahwa semua ikan transgenik (n=20) yang diidentifikasi dapat diklasifikasikan secara jelas sebagai ikan homosigot atau heterosigot. Persilangan antara ikan transgenik tersebut dengan ikan normal menunjukkan transmisi transgen ke keturunannya mengikuti hukum segregasi Mendel. Dengan demikian, metode krt-PCR adalah efektif untuk penentuan sigositas secara cepat dan tepat pada ikan transgenik. Teknik ini dapat berguna dalam program produksi ikan transgenik secara massal dan dalam percobaan dimana faktor sigositas memberikan pengaruh nyata. Kata kunci: kuantitatif real-time PCR; sigositas, ikan transgenik; produksi massal

Cherax quadricarinatus is one of freshwater crayfish species that has enormous potential for expanding its farming in future. Application of monosex male culture using steroid sex hormone administration method during the period of sex differentiation or early developmental stage might be increased efficiency in farming. This study was aimed to increase male of C. quadricarinatus by oral administration of diet containing 17α-methyltestosterone (MT) towards production efficiency. Two-week-old of Cherax quadricarinatus were fed ad libitum on diets containing various dose of MT, i.e., 25, 50, 75, 100 and 150 mg/kg diet or diet containing no MT as control, 3 times daily for 30 days. After MT-treatment, crayfish were fed frozen Chironomus sp. and shrimp diet. Sex ratio, survival and growth rate (by length and weight) were observed at the end of experiment. Sex was determined by visual observation; the male sex organ is located at the fifth walking leg while the female is at the third. Data was analyzed by F and BNT tests. The results of study show that administration of MT was significantly changed the male ratio of crayfish. Treatment dose of 50 mg/kg diet was effective to increase male sex percentage from 24.93% (control) to be 59.96%. Growth was also significantly being improved, while survival rate was insignificant. Thus, oral administration of MT is an effective way to increase male sex percentage of crayfish, although other methods and the time of hormone administration are needed to be verified to obtain maximal results. Keywords: monosex, 17α-methyltestosterone, sex reversal, Cherax quadricarinatus ABSTRAK Salah satu jenis lobster air tawar yang berpotensi tinggi untuk dikembangkan usaha budidayanya adalah Cherax quadricarinatus. Aplikasi teknik budidaya tunggal kelamin (monoseks) dengan metode pemberian hormon seks steroid yang diberikan pada saat diferensiasi kelamin atau masa perkembangan awal ikan diduga dapat meningkatkan efisiensi usaha. Penelitian ini ditujukan untuk meningkatkan persentase C. quadricarinatus jantan menggunakan metode seks reversal melalui pemberian pakan yang mengandung 17α-metiltestosteron (MT) sebagai upaya efisiensi produksi. C. quadricarinatus umur 2 minggu diberi pakan yang mengandung MT dengan dosis 25, 50, 75, 100 dan 150 mg/kg pakan atau tanpa hormon secara ad libitum, 3 kali sehari selama 30 hari. Setelah perlakuan lobster uji diberi pakan alami Chironomus sp. beku dan pakan udang. Parameter yang diamati meliputi nisbah kelamin, kelangsungan hidup dan pertumbuhannya (panjang dan berat mutlak), yang dilakukan pada akhir penelitian. Identifikasi jenis kelamin dilakukan secara visual; alat kelamin lobster jantan terdapat pada bagian pangkal kaki jalan kelima, yang betina terletak pada bagian dasar kaki jalan ketiga. Data dianalisis menggunakan uji F dan BNT. Hasil penelitian menunjukkan bahwa pemberian hormon MT berpengaruh nyata terhadap persentase kelamin jantan lobster. Perlakuan dengan dosis 50 mg/kg pakan efektif untuk meningkatkan persentase jantan C. quadricarinatus dari 24,93% (kontrol) menjadi 59,96%. Pertumbuhan panjang dan berat mutlak juga menunjukkan pengaruh yang berbeda nyata, sementara kelangsungan hidup tidak berbeda. Dengan demikian pemberian hormon MT melalui pakan cukup efektif untuk meningkatkan persentase lobster jantan yang dihasilkan, meskipun penggunaan metode lain dan waktu pemberian hormon MT masih perlu diteliti untuk memperoleh hasil maksimal.

Promoter is one of the factors determining the successful of transgenesis. In this study we isolated and characterized β-actin promoter from Nile tilapia (tiBP) towards production of autotransgenic tilapia. β-actin promoter has high activity in muscle. Sequence of tiBP promoter was isolated by using PCR method. Sequencing was performed using ABI PRISM 3100 machine. Analysis of sequences was conducted using GENETYX version 7 and TFBind softwares. DNA fragment of PCR amplification product digested from the vector cloning was then ligated with pEGFP-N1 to generate ptiBP-EGFP construct. The construct was microinjected into one-cell stage of zebrafish (Danio rerio) embryos to test the tiBP promoter activity. EGFP gene expression was observed by fluorescence microscope. The result of sequence analysis showed that the length of DNA fragment obtained is about 1.5 kb and containing the evolutionary conserved sequences of transcription factor for β-actin promoter including CCAAT, CArG and TATA boxes. Furthermore, tiBP sequence in ptiBP-EGFP construct could regulated GFP expression in muscle of zebrafish embryos injected with the construct. The results suggested that PCR amplification product is the regulator sequence of tilapia β-actin gene. Autotransgenic tilapia can be then produced by changing GFP gene fragment of ptiBP-EGFP construct with genes from tilapia encoding important traits in aquaculture. Keywords: cloning, β-actin promoter, autotransgenic, EGFP, Oreochromis niloticus, Danio rerio ABSTRAK Promoter merupakan salah satu faktor penentu keberhasilan transgenesis. Pada penelitian ini kami mengisolasi dan mengkarakterisasi promoter β-actin dari ikan nila (tiBP) dalam rangka pembuatan ikan nila autotransgenik. Promoter β-actin memiliki aktivitas tinggi pada jaringan otot. Sekuens promoter tiBP diisolasi menggunakan metode PCR. Sekuensing dilakukan menggunakan mesin ABI PRISM 3100. Analisa sekuens menggunakan software GENETYX versi 7 dan TFBind. Fragment DNA hasil amplifikasi PCR yang didigesti dari vektor kloning selanjutnya diligasi dengan pEGFP-N1 untuk membuat konstruksi ptiBP-EGFP. Konstruksi ptiBP-EGFP dimikroinjeksi ke embrio ikan zebra (Danio rerio) fase 1 sel untuk menguji aktivitas promoter tiBP. Ekspresi gen EGFP diamati menggunakan mikroskop fluoresens. Analisa sekuens menunjukkan bahwa panjang fragmen DNA hasil amplifikasi PCR sekitar 1,5 kb dan memiliki faktor transkripsi yang konserf untuk promoter β-actin, yaitu CCAAT, boks CArG dan TATA. Selanjutnya, sekuens tiBP dalam konstruksi ptiBP-EGFP mampu mengendalikan ekspresi gen EGFP pada jaringan otot embrio ikan zebra yang dimikroinjeksi dengan konstruksi tersebut. Dengan demikian dapat disimpulkan bahwa fragmen DNA hasil amplifikasi PCR tersebut merupakan sekuens promoter β-actin ikan nila. Pembuatan ikan nila autotransgenik selanjutnya dapat dilakukan dengan mengganti gen EGFP pada pktBA-EGFP dengan gen-gen asal ikan nila yang mengkodekan karakter penting dalam budidaya ikan.

The study was aimed to determine the effectiveness of DNA vaccine doses on hematological aspect which represent immune response and its influence on common carp survival rate. DNA vaccines encoding the viral glycoprotein of koi herpesvirus (KHV) have been proved to highly protect the fish under laboratory condition. A dose of 12.5 µg/100 µl vaccine had resulted in a survival rate of 96.67 % during 30 days after challenge test with a lethal dose of KHV. Fish vaccinated using lower doses, i.e. 2.5 and 7.5 µg/100µl showed 100% mortality after 15 and 19 days challenge test respectively, whereas non vaccinated fish as a control showed 100% mortality after 17 days challenge test. Total leucocytes of the vaccinated fish were higher than control until 42 days post vaccination, but declined afterward. Phagocytic index of the vaccinated fish using 12.5 µg/100 µl was declined after 49 days post vaccination or 7 days post challenge test. Key words: DNA vaccine, Koi herpesvirus (KHV), leucocyte, phagocytic index, Cyprinus carpio ABSTRAK Penelitian ini bertujuan untuk menguji pengaruh vaksinasi menggunakan vaksin DNA dengan dosis berbeda terhadap gambaran darah ikan sebagai respresentasi tanggap kebal ikan mas serta pengaruhnya terhadap tingkat kelangsungan hidup ikan mas. Vaksin DNA penyandi glikoprotein koi herpesvirus (KHV) dapat memberikan proteksi yang tinggi pada percobaan skala laboratorium. Vaksinasi dengan dosis 12,5 µg/100µl dapat mempertahankan kelangsungan hidup sebesar 96,67% selama satu bulan setelah uji tantang dengan virus KHV menggunakan dosis letal. Ikan yang divaksin dengan dosis yang lebih rendah yaitu 2,5 dan 7,5 µg/100µl mengalami kematian total berturut-turut setelah 15 dan 19 hari uji tantang, sedangkan ikan kontrol yang tidak divaksin mengalami kematian total setelah 17 hari uji tantang. Jumlah leukosit total ikan yang divaksinasi lebih tinggi dibanding dengan kontrol sampai hari ke-42, setelah itu mengalami penurunan.

Promoter in transgene construct plays an important role on regulating of transgene expression level in transgenic fish. In fish transgenesis, researcher convinced that use all-fish gene construct is safety and prospective. This study was performed to compare effectiveness b-actin promoter, - the promoter which has ubiquitous, constitutive, housekeeping characteristics, from common carp (homologous) and from tilapia and medaka b-actin promoters (heterologous) in driving of green fluorescent protein (GFP) expression as a model of target gene on common carp transgenesis. These gene constructs were separately microinjected into cytoplasm of 60 one-cell-stage common carp embryos. The results suggested that 70% survival rate at embryo stage and 45% hatching rate values showed that the microinjection was performed successfully. Percentage of embryos expressing GFP gene were slightly higher when injected using common carp and medaka promoters than those of using tilapia promoter. Percentage of larvae expressing GFP using common carp promoter was similar with medaka promoter. Furthermore, GFP expression using common carp b-actin promoter could be detected at one-week-old larvae, while GFP expressing using medaka b-actin promoter was lasted at 2-day-old larvae. The results demonstrated that homologous promoter more effective in driving of a target gene expression than that of heterologous promoter. Key words: homologous promoter, GFP, transgenesis, common carp ABSTRAK Promoter dalam konstruksi transgen berperan penting dalam pengaturan tingkat ekspresi transgen pada ikan transgenik. Dalam transgenesis ikan, peneliti meyakini bahwa penggunaan konstruksi gen "all-fish" adalah aman dan prospektif. Penelitian ini dilakukan untuk membandingkan efektivitas promoter β-aktin, - promoter yang memiliki ciri ubiquitous, constitutive, dan housekeeping, dari ikan dari ikan mas (homolog) dan ikan nila dan ikan medaka (heterolog) dalam mengendalikan ekspresi gen GFP sebagai model gen pada transgenesis ikan mas. Setiap konstruksi gen tersebut diinjeksikan secara terpisah ke sitoplasma embrio ikan mas fase 1 sel sebanyak 60 embrio. Hasil penelitian dengan kelangsungan hidup embrio 70% dan derajat penetasan 45% menunjukkan bahwa kegiatan mikroinjeksi berhasil dengan baik. Persentase embrio mengekspresikan gen GFP yang diinjeksi konstruksi gen dengan promoter β-aktin ikan mas dan ikan medaka sedikit lebih tinggi dibandingkan dengan yang menggunakan promoter β-aktin ikan nila. Selanjutnya, ekspresi gen GFP yang dikendalikan oleh promoter β-aktin ikan mas dapat dideteksi pada larva berumur 1 minggu, sedangkan ekspresi GFP dengan promoter β-aktin ikan medaka hanya bisa terdeteksi hingga larva berumur 2 hari. Hasil penelitian menunjukkan bahwa promoter homolog adalah lebih efektif dalam mengatur ekspresi gen target dibandingkan dengan promoter heterolog.

This study aimed to produce recombinant growth hormone (rGH) protein of common carp (Cyprinus carpio) and evaluate its bioactivity. DNA fragment encoding mature GH protein of common carp (mCcGH) was amplified by polymerase chain reaction (PCR) method and PCR products were then ligated into pCold I to generate pCold I-mCcGH protein expression vector. Escherichia coli BL21 (DE3) harboring pCold I-mCcGH was cultured in the 2xYT medium at 15 °C for 24 hours and protein production was induced by isopropyl-beta-thio galactopyranoside (IPTG). The inclusion bodies containing rGH protein from E. coli transformants were isolated by sonication method and analyzed by SDS-PAGE. The result showed that rGH with molecular weight of about 25 kDa was obtained. Common carp juveniles with average body weight of 5.2±0.4 g were intramuscularly injected once a week for 4 weeks with rGH protein solution from 1 μg bacterial cells per gram fish body weight. The result showed that juveniles fish injected with rGH grew 106.56% higher than control. This result indicated that rGH produced in E. coli BL21 possessed biological activity and it may be useful to improve growth of aquaculture species.Key words: growth hormone, recombinant protein, common carp ABSTRAKPenelitian ini bertujuan menghasilkan protein rekombinan hormon pertumbuhan (growth hormone, GH) dari ikan mas (Cyprinus carpio) dan menguji bioaktivitasnya. Fragmen DNA penyandi protein matang (mature) GH ikan mas (mCcGH) diamplifikasi dengan menggunakan metode PCR dan hasilnya kemudian diligasi ke dalam pCold-I untuk menghasilkan konstruksi vektor ekspresi pCold-I-mCcGH. Plasmid pCold-I-mCcGH ditransformasi ke bakteri Escherichia coli BL21 (DE3), dikultur dalam media 2xYT cair pada suhu 15°C selama 24 jam dan produksi protein diinduksi dengan menggunakan isopropyl-beta-thio galactopyranoside (IPTG). Badan inklusi yang mengandung protein rekombinan GH (rGH) dari bakteri E. coli transforman diisolasi menggunakan metode sonikasi dan dianalisis dengan menggunakan SDS-PAGE. Hasil penelitian menunjukkan bahwa rGH dengan bobot molekul sekitar 25 kDa berhasil diproduksi. Benih ikan mas dengan bobot rata-rata 5,15±0,4 g diinjeksi secara intramuskular satu kali per minggu selama 4 minggu dengan larutan rGH hasil ekstraksi dari 1 µg pelet bakteri/g bobot ikan. Benih yang disuntik dengan rGH tumbuh sekitar 100% lebih cepat bila dibandingkan dengan kontrol yang tidak diinjeksi rGH.

This study was aimed to determine the immersion frequency of recombinant growth hormone (rGH) in the growth stimulation of giant gourami juvenile. A total of 50 larvae at second day after first feeding, was immersed in 30 ppt salt water for 2 minutes, and then transferred into 200 mL of 9 ppt salt water containing 30 mg/L rGH in inclusion bodies form. Immersion was performed for 60 minutes and repeated once a week for two, three, four, and five weeks. As the control, fish was immersed with inclusion bodies without rGH (control-1), bovine serum albumin (control-2), 9ppt saline water without rGH (control-3) and in freshwater (control-4). Fish were kept in 7L aquaria during the first four weeks, transferred into 50L aquaria for two weeks, and then in hapa (2×1×1 m3 in size) for two weeks. The results showed that the highest (p<0.05) average body weight of giant gourami juvenile (2.23±0.19 g) was obtained at four times (four weeks) immersion treatment. Similar body weight of fish in two times (1.72±0.29 g), three times (1.68±0.34 g), and five times (1.81±0.17 g) immersion was obtained. Fish body weight of all controls was lower than the rGH-immersed fish. Average body weight of four time rGH-immersed fish (4.01 g) remained higher than other treatment and control (1.96 to 2.36 g) on 8th week of fish rearing. Survival of four times (96.67±1.15%), and five times rGH-immersion fish (95.33±4.16%) was similar, and higher than other treatments and controls (77.33 to 89.33%). Thus, higher growth rate and survival of giant gourami juvenile could be achieved by four times rGH immersion. Keywords: recombinant protein, growth hormone, immersion frequency, giant gourami

Koi herpesvirus (KHV) is a herpesvirus that particularly infects and causes mass mortality to koi and common carp. Therefore, the protection of common carp from KHV infection is urgently needed. In this study, we developed an application of DNA vaccine encoding KHV glycoprotein-25 by immersion method to increase survival of common carp against KHV infection. A total of 400 common carp juveniles at 30-day-old were immersed in 1-L water containing 1.3×108CFU/mL of the killed Escherichia coli cells carrying DNA vaccine. Three frequencies and three duration of fish immersion were tested, namely: 1×30 minutes, 1×60 minutes, 1× 90 minutes, 2×90 minutes and 3×90 minutes by interval of 24 hours. Reversetranscription polymerase chain reaction analysis showed that DNA vaccine was successfully expressed in the vaccinated fish. Fish at twenty eight days post vaccination were challenged by injecting 10-4 mL of KHV per fish. The result showed that vaccination by 1×30 minutes immersion allowed 61% of fish survived, and this was significantly higher (p<0.05) compared to control (without vaccination), but it was similar among vaccination treatments (p>0.05). The relative percent survival of vaccinated fish were also similar among treatments (p>0.05). DNA vaccination has increased fish survival about two fold higher compared to unvaccinated fish control (26.67%). Thus, DNA vaccination was effectively delivered by immersion for 1×30 minutes, and this technique can be useful to level up the resistance of common carp juveniles against KHV infection.

This study was aimed to determine the immersion dose of recombinant giant grouper growth hormone (rElGH) to increase growth of eel juvenile (glass eel). After shock salinity treatment (NaCl 3% for 2 min), glass eel were immersed in water containing 0.9% NaCl, 0.01% bovine serum albumin, and different of dose of rElGH (0, 0.12, 1.2, 12 and 120 mg/L). Glass eel were fed on blood worm for the first month, and commercial diet for the second month of rearing. Fish rearing was performed in 60 L glass aquarium at density of 150 fish per aquarium. The results showed that higher in growth body weight was obtained in immersion dose of 12 mg/L, by increment of about 37.4% higher compared to that of control. The immersion dose of 12 mg/L also increased specific growth rate by 29.3% higher (p<0.05) compared to control. Furthermore, at that immersion treatment, feed conversion ratio of blood worm and commercial diet decreased by 33.7% and 25.6% compared to control, respectively. Protein (7.15±0.08%) and lipid (9.95±0.10%) retentions in 12 mg/L rElGH-treated fish were higher (p<0.05) than those of control (protein 6.17±0.07%; lipid 5.73±0.06%). Lower in protein content (12.73%), while higher content in lipid (8.35%) and crude carbohydrate (3.22%) were found in 12 mg/L rElGH-treated fish compared to those of control (13.24%, 5.90%, and 1.76%, respectively). Thus, in general, rElGH immersion dose of 12 mg/L could generate high performances of eel juvenile, and application of rElGH can be useful to increase aquaculture eel production.Keywords: immersion dose, growth hormone, growth, glass eel
