ABSTRAK
Latar belakang: SOPK adalah gangguan endokrin yang hingga saat ini etiologinya masih belum jelas. Faktor epigenetik metilasi DNA, akhir-akhir ini mendapatkan perhatian dalam patogenesis SOPK. Gen HSD17B1 disebut sebagai "estrogenik" 17β-HSD karena mengkatalisasi langkah terakhir dalam biosintesis estrogen dengan secara istimewa mengurangi estrone, estrogen yang lemah untuk menghasilkan estrogen 17β-estradiol yang kuat. Kami berspekulasi cacat pada metilasi DNA mendorong deregulasi gen sehingga terjadi penurunan ekspresi mRNA HSD17B1, akhirnya menghasilkan estradiol yang tidak cukup pada pasien SOPK. Metode: Kami mengumpulkan total 60 pasien wanita. MSP untuk analisis metilasi DNA, qPCR untuk analisis ekspresi mRNA. Tujuan: Untuk menganlisis metilasi DNA pada kelompok pasien SOPKdan kelompok wanita sehat, ekspresi mRNA pada kelompok pasien SOPK dan kelompok wanita sehat, tingkat estradiol pada pasien SOPK dan kelompok wanita sehat, korelasi antara metilasi DNA dan ekspresi mRNA pada pasien SOPK, korelasi ekspresi mRNA pada pasien SOPKdan kadar serum estradiol. Hasil: Metilasi gen HSD17B1 pada wanita SOPK adalah 42,64% dan kelompok yang sehat menunjukkan 53,80%, p = 0,160 tidak signifikansi antara kedua kelompok. Nilai ekspresi relatif gen HSD17B1 adalah 0,70 kali lebih rendah dibandingkan dengan kelompok wanita sehat, p = 0,003 signifikansi antara kedua kelompok. Estradiol rata-rata pada kelompok SOPK25,78 pg / ml dan kelompok wanita sehat adalah 36,74 pg / ml. Korelasi tingkat metilasi DNA versus ekspresi mRNA pada pasien SOPK, tidak signifikan p = 0,076. Korelasi antara ekspresi mRNA gen HSD17B1 dan kadar serum estradiol, signifikansi p = 0,020. ;Semakin terjadi penurunan ekspresi mRNA, semakin rendah kadar serum estradiol.
ABSTRACT
Background: PCOS is the most common endocrine disorder but its etiology remains unclear. Lately, epigenetic factors have gained considerable attention in the pathogenesis of PCOS, DNA methylation.  HSD17B1 is referred to as the "estrogenic" 17β-HSD because it catalyzes the final step in estrogen biosynthesis by preferentially reducing the weak estrogen estrone to yield the potent estrogen 17β-estradiol. We speculated defects in DNA methylation promote the deregulation of genes make decrease mRNA expression HSD17B1, finally produces not enough estradiol in PCOS patients. Methods: We collected a total of 60 female patients. MSP for DNA methylation analysis, qPCR for mRNA expression analysis. Aims: To investigate, DNA methylation in PCOS patients group and healthy women group, mRNA expression in PCOS patients group and healthy women group, estradiol level in PCOS patients and healthy women group, the correlation between DNA methylation and mRNA expression in PCOS patients, correlation mRNA expression in PCOS patients and estradiol serum level. Results: Methylated of HSD17B1 gene in PCOS women was 42.64 % and a healthy group showed 53.80 %, p=0.160 not significances between the two groups.  The relative expression value of the HSD17B1 gene was 0.70 fold lower compare with a healthy women group, p=0.003 significance between the two groups. The average estradiol in the PCOS group 25.78 pg/ml and the healthy women group is 36.74 pg/ml. Correlation of DNA methylation level versus mRNA expression in PCOS patients, not significance p=0.076. Correlation between mRNA expression of the HSD17B1 gene and estradiol serum level, significance p=0.020. (More decrease mRNA expression, more lower estradiol serum level).

Abstrak :
Latar belakang: Kedelai (Glycine max (L.) Merr.) merupakan tanaman yang sedang dikembangkan aktivitasnya sebagai antikanker. Salah satu senyawa aktifnya adalah Lunasin. Permasalahannya harga lunasin komersial sangat mahal karena biaya sintesis lunasin yang besar dan lama. Pada penelitian ini akan dikembangkan sediaan ekstrak tertarget Lunasin (ET-Lun) dengan tujuan untuk membuktikan aktivitas antikanker payudara ET-Lun secara in silico dan in vivo. Metode: Uji In silico, senyawa aktif pada kedelai sebagai ligan dilihat ikatannya terhadap protein ERα, ERβ, HER2, dan EGFR. Pengujian in vivo dibagi menjadi 2 kelompok besar yaitu kelompok kuratif dan preventif. Pada kelompok kuratif, tikus SD diinduksi dengan DMBA 20 mg/kg BB sebanyak 11 kali, 2 kali dalam seminggu kecuali kontrol normal (NOR). Setelah terbentuk nodul dengan volume 1-2 cm3, tikus diberikan perlakuan selama 8 minggu dengan tamoksifen 10 mg/kg BB (TAM), ET-Lun 500 mg/kg BB (ET- Lun), kombinasi ET-Lun dan tamoksifen (ADJ). Pada kelompok kontrol negatif (DMBA) pertumbuhan tumor diamati selama 8 minggu. Kelompok preventif (PREV), diberikan ET-Lun 1 minggu sebelum, selama, dan setelah induksi DMBA selama 24 minggu. Setelah perlakuan, tikus diterminasi, dan diambil tumornya. Volume tumor diukur, dan dilakukan pemeriksaan eskpresi ERα, ERβ, HER2, dan EGFR secara imunohistokimia dan qPCR. Hasil: Uji in silico menunjukkan Genistein dan Lunasin mempunyai afinitas terbesar terhadap ERα, ERβ, dan EGFR. Uji in vivo menunjukkan ET-Lun kelompok preventif dapat menekan pertumbuhan tumor sebesar 80%, sedangkan kelompok kuratif, terjadi perlambatan pertumbuhan tumor dibandingkan kelompok DMBA yaitu 0,31 kali pada kelompok ET-Lun; 0,37 kali pada tamoksifen; dan 0,15 kali pada kelompok adjuvan selama 8 minggu perlakuan. Secara molekuler, ET-Lun kelompok preventif dan kuratif dapat menurunkan ekspresi protein dan mRNA ERα, serta ekspresi protein EGFR jika dibandingkan kelompok DMBA. Kesimpulan: ET-Lun berpotensi sebagai kandidat antikanker pada pencegahan dan perlambatan karsinogenesis payudara tikus SD yang diinduksi DMBA. ......Background: Soybean (Glycine max (L.) Merr.) is a plant that is being developed for its anticancer activity. One of the active compounds is Lunasin. The problem is that the price of commercial lunasin is very expensive because of the high cost of synthesizing lunasin and it takes a long time. In this study, the soybean extract with targeted lunasin (ET-Lun) will be developed with the aim of proving the anti-breast cancer activity of ET-Lun in silico and in vivo. Method: In silico study, the active compounds in soybean as a ligand was seen for their binding to ERα, ERβ, HER2, and EGFR. In vivo assay, the rat was randomized into 2 major groups, namely curative and preventive groups. In the curative group, the SD rats were induced with DMBA 20 mg/kg BW 11 times, 2 times a week, except for normal controls (NOR). After forming nodules with a volume of 1-2 cm3, the rats were treated with tamoxifen 10 mg/kg BW (TAM), ET-Lun 500 mg/kg BW (ET-Lun), a combination of ET-Lun and tamoxifen (ADJ), for 8 weeks. For negative controls (DMBA), tumor growth in rats was observed in 8 weeks. In the preventive group (PREV), was given ET- Lun 1 week before, during, and after DMBA induction for 24 weeks. After treatment, all the rats were terminated, and the tumors were taken. Tumor volume was measured, and ERα, ERβ, HER2, and EGFR expression were examined by immunohistochemistry and qPCR. Results: In silico study showed the Genistein and Lunasin had the greatest affinity for ERα, ERβ, and EGFR. In vivo study showed ET-Lun in the preventive group could suppress tumor growth by 80%, while in the curative group, ET-Lun could delay tumor growth by 0,31 times DMBA, tamoxifen 0,37 times DMBA, and adjuvant group 0,15 times DMBA, in 8 weeks of treatment. Molecularly, ET-Lun in the preventive and curative group, could decrease the expression of ERα protein and mRNA, as well as the expression of EGFR protein when compared to the DMBA group. Conclusion: ET-Lun has potential as an anticancer candidate for the prevention and delays of tumor growth in the DMBA-induced breast cancer rat model.
