"Tujuan: Menilai keberadaan reseptor PPARγ serta membandingkan tampilan reseptor PPARγ pada endometrium eutopik dan ektopik pada penderita endometriosis Metode: Penelitian ini merupakan penelitian potong lintang (cross sectional). Sepuluh subjek penderita endometriosis yang menjalani laparoskopi atau laparotomi, yang masuk dalam kriteria penerimaan (consecutive sampling) diambil dua percontoh, yakni endometrium eutopik dan endometrium ektopik yang berasal dari dinding kista endometriosis saat dilakukan pembedahan kemudian dilihat tampilan reseptor PPARγ dengan two-step RT-qPCR. Tampilan masing-masing percontoh diuji statistik dengan uji tes-t berpasangan dan tes korelasi Pearson. Hasil: Didapatkan tampilan reseptor PPARγ pada endometrium eutopik dan endometrium ektopik penderita endometriosis dengan metode RT-qPCR. Tampilan resptor PPARγ endometrium eutopik dan ektopik didapatkan secara statistik tidak berbeda bermakna (1.16 lipatan relatif vs 1.25 lipatan relatif; p=0.26). Pada uji korelasi Pesrson didapatkakan korelasi positif lemah antara tampilan PPARγ endometrium eutopik dan ektopik (r=0.16). Kesimpulan: Tampilan reseptor PPARγ pada endometrium eutopik dan ektopik penderita endometriosis didapatkan dengan metode two-step RT-qPCR. Dengan semikuantifikasi tampilan reseptor PPARγ tidak didapatkan perbedaan antara tampilan reseptor PPARγ pada endometrium eutopik dan ektopik pada penderita endometriosis. Terdapat korelasi positif lemah antara tampilan reseptor PPARγ pada endometrium eutopik dan ektopik pada penderita endometriosis.

Objective: To evaluate the expression of the PPARγ receptor and to compare its expression in the eutopic and ectopic endometrium in women with endometriosis Method: This is a cross sectional study. Ten female subjects with endometriosis that underwent laparoscopy or laparotomy that fulfilled the inclusion criteria were recruited by consecutive sampling. Two samples were taken, eutopic endometrium and ectopic endometrium from endometriosis cyst wall during surgery of each subject, PPARγ expression was examined by two-step RT-qPCR. Each sample was statistically examined using the paired t-test and Pearson’s corelation test.

Result: PPARγ was found to be expressed in the eutopic and ectopic endometrium of women with endometriosis using the RT-qPCR method. The expression of PPARγ was not statistically different in eutopic and ectopic endometrium (1.16 relative fold vs 1.25 relative fold:p=0.26). By Pearson’s corelation there was a weak positive corelation between PPARγ expression of the eutopic and ectopic endometrium (r=0.16).

Conclusion: PPARγ was detected by two-step RT-qPCR in eutopic and ectopic endometrium of women with endometriosis. Semiquantification of PPARγ expression showed that there was no significant difference betweenits expression in the eutopic and ectopic endometrium of women with endometriosis. There was a weak postive corelation of PPARγ expression between the eutopic and ectopic endometrium of women with endometriosis."

"Latar belakang: Resistensi progesteron akibat gangguan ekspresi reseptor progesteron pada jaringan endometriosis telah diketahui menjadi faktor yang memperberat kondisi klinis pasien endometriosis. Tujuan penelitian ini adalah untuk menganalisis tingkat metilasi DNA pada promoter gen PR-B pada berbagai jaringan endometriosis seperti eutopik endometrium, lesi ektopik peritoneum, endometrioma dan darah menstruasi serta pengaruhnya terhadap ekspresi mRNAnya dibandingkan dengan kontrol endometrium normal; untuk mengetahui patomekanisme endometriosis pada berbagai lokasi terkait dengan resistensi progesteron.Metode: Penelitian ini menggunakan desain potong lintang yang melibatkan 20 sampel untuk masing-masing kelompok kasus dan kontrol. Tingkat metilasi DNA dari gen PR-B diukur menggunakan metode Methylated Specific PCR MSP lalu intensitas pita di dalam gel agarose dihitung dengan software ImageJ. Presentase intensitas pita pada sampel dibandingkan dengan kontrol positif disebut dengan tingkat metilasi DNA. Pengukuran ekspresi relatif mRNA PR-B menggunakan qRT-PCR dua tahap dan analisis dilakukan dengan metode Livak.Hasil: Dari penelitian ini didapatkan perbedaan bermakna antara tingkat metilasi DNA gen PR-B pada jaringan endometriosis ektopik peritoneum 72,4 termetilasi , endometrioma 85 termetilasi dan eutopik endometrium 72,21 termetilasi dibandingan dengan kontrol p

Background: Progesterone resistance, due to alteration of progesterone receptor PR expression in endometriosis, was known as a disrupt factor in response to progesterone. The aim of this study is to analyze DNA methylation level on PR B promoter in various tissues include eutopic endometrium, ectopic peritoneal, endometrioma and menstrual blood from endometriosis patient as well as the implication on it's mRNA relatif expression compare with normal endometrium control to know the patomechanisms of endometriosis in various lession in term of progesterone resistance.

Methods: It was a cross sectional study, involved 20 sample for both patient and control. DNA isolate from each sample were converted by bisulfite conversion. DNA methylation level of PR B gene was analysis by Methylated Specific PCR MSP method, then band intensity in gel agarose was measured by ImageJ software. Percentage of band intensity in sample compared with positive control was determined as DNA methylaton level. Quantitative real time PCR was conducted to assess expression of mRNA PR B for each sample and Livak method was used to analysis it's relatif expression compare with control.

Result: There were significant different of methylation level of PR B gene in ectopic peritoneal endometriosis 72,40 methylated , endometrioma 85 methylated and eutopic endometrium 72,21 methylated compared with control p"
