"Apoptosis or programmed cell death is a normal condition for development and live multicellular organism. Apoptosis is a morphological phenomenon that play important role in physiological processes during fetal development and in adult. Mitochondria play an important role in apoptosis. Mitochondria can do apoptosis directly. Mitochondria has 2 family of protein Bcl-2. Bcl-2 and Bcl-XL are anti apoptosis while Bad and Bax are pro apoptosis. There are 3 different mechanism apoptosis. One generated by signals arising within the cell another triggered by death activators binding to receptors at the cell surface and a third may be triggered by dangerous agent that different from two ways before. Apoptosis also need caspase as cell death executor. Study of apoptosis still done especially in case of disease. Some disease have known related with disturbing of apoptosis mechanism for example cancer and auto immun. This article reviews about molecular mechanism of apoptosis for understanding disease and future therapy."

Latar Belakang: Cisplatin telah menjadi terapi lini pertama untuk kanker ovarium, namun efek samping terbesar cisplatin adalah peningkatan resistensi sel kanker yang menyebabkan hepatotoksisitas pada sel normal. Kurkumin terbukti memiliki sifat hepatoprotektif, tetapi efek terapeutik kurkumin terbatas karena memiliki bioavailabilitas yang rendah. Penggunaan kitosan nanopartikel pada kurkumin telah terbukti meningkatkan bioavailabilitas kurkumin sehingga efektivitasnya lebih besar. Penelitian ini dilaksanakan untuk melihat pengaruh nanokurkumin terhadap hepatotoksisitas akibat pemberian cisplatin. Tujuan: Membandingkan pengaruh kurkumin dan nanopartikel kurkumin untuk digunakan sebagai ko-kemoterapi dengan cisplatin pada kanker ovarium tikus yang ditinjau melalui jalur apoptosis, khususnya marker Bax dan Kaspase-3. Metode: Penelitian ini merupakan penelitian eksperimental in vivo pada model kanker ovarium tikus betina galur Wistar yang diinduksi 7,12-dimethybenzen[a]anthracene (DMBA) dan dilaksanakan di Departemen Farmakologi dan Terapeutik Fakultas Kedokteran Universitas Indonesia sejak bulan Juni 2019 hingga Juni 2020. Cisplatin diberikan dalam dosis sebesar 4 mg/kgBB secara intraperitoneal. Kurkumin dan nanokurkumin diberikan dalam dosis oral sebesar 100 mg/kgBB. Organ tersimpan hepar yang diambil dari 25 ekor tikus terbagi menjadi 5 kelompok perlakuan, yaitu kelompok tikus normal, model kanker ovarium tikus, terapi cisplatin, terapi cisplatin + kurkumin, dan terapi cisplatin + nanokurkumin. Setelah dikelompokkan, dilakukan homogenisasi sampel yang terpilih. Lalu, RNA Bax dan Kaspase-3 diisolasi dari homogenat sampel organ hepar dan cDNA kedua gen disintesis. Kemudian, tingkat ekspresi mRNA Bax dan Kaspase-3 pada hepar diukur menggunakan qRT-PCR. Data ekspresi mRNA Bax dan Kaspase-3 dianalisis dan diuji korelasi antarkelompok menggunakan aplikasi SPSS. Hasil: Tidak ada perbedaan yang signifikan antara kelima kelompok pada tingkat ekspresi mRNA Bax (p=0,372) dan Kaspase-3 (p=0,111). Kesimpulan: Tidak ditemukan pengaruh kurkumin dan nanokurkumin terhadap ekspresi mRNA Bax dan Kaspase-3 organ hepar pada model kanker ovarium tikus setelah pemberian terapi cisplatin.

Introduction: Endometriosis is one of common conditions causing infertility and an indication to undergo in vitro fertilization (IVF). High apoptosis rate and oxidative stress in patient with endometriosis is believed to cause negative effect on IVF success rate. However, there has been conflicting results on endometriosis effect to IVF success and there have been limited studies that directly assess endometriosis and its effect on oocyte quality.

Aim: To assess apoptosis rate on granulosa cells in patients with endometriosis compared to non-endometriosis patients through mRNA BAX/BCL-2 ratio and how it correlates with oocyte quality collected during ovum pick up.

Results: Samples were collected from 15 subjects with endometriosis and 15 control subjects. Total dose of recombinant FSH received by endometriosis group is significantly higher compared to control (p=0.005). There is difference in BAX level (p=0.029) and BCL-2 level (p<0.001) in both groups. However, the ratio does not differ significantly (p=0.787). No significant correlation is found in BAX/BCL-2 ratio and any of the oocyte quality parameters.

Conclusion: We found no significant difference in BAX/BCL-2 ratio between endometriosis and control group as well as significant correlation between the ratio and oocyte quality."

"[ABSTRAKLatar Belakang: Kanker prostat adalah kanker yang paling umum pada pria. Kanker terjadi karena hilangnya kontrol atas proliferasi sel dan apoptosis sehingga sel berproliferasi terus menerus tanpa ada kematian sel. Apoptosis diregulasi oleh beberapa protein tertentu diantaranya protein keluarga Bcl-2 dan protein kanal. Perkembangan kanker prostat memerlukan transformasi dari sel epitel yang normal menjadi sel ganas yang kehilangan kemampuan untuk mengakumulasi zinc. Salah satu efek utama zinc adalah mencegah pertumbuhan sel kanker prostat dengan menginduksi apoptosis dengan memfasilitasi proses pembentukan pori Bax yang memulai apoptogenesis mitokondria. Selain keluarga Bcl-2, VDAC1 juga berperan penting dalam proses apoptosis. Beberapa penelitian menyatakan Bcl-2 mempunyai kaitan erat dengan VDAC1 terkait proses apoptosis dan protein pro-apoptotik Bax juga secara langsung berinteraksi dengan VDAC yang kemudian menginduksi keluarnya sitokrom c dari membran mitokondria.Tujuan: Mengevaluasi ekspresi mRNA dari gen mengkode keluarga protein Bcl-2 (Bax dan Bcl-2) dalam proses apoptogenesis pada galur sel kanker prostat yg diinduksi oleh zinc; Mengevaluasi ekspresi mRNA dari gen VDAC1 dalam proses apoptogenesis pada galur sel kanker prostat yang diinduksi oleh zinc; Menganalisis hubungan antara ekspresi VDAC1 dengan protein keluarga Bcl-2 pada apoptogenesis galur sel kanker prostat.Desain: Penelitian ini menggunakan eksperimental in vitro dan analisis statistikMetode: Untuk memperbanyak galur sel kanker prostat (PC3) dilakukan kultur sel, kemudian diberi perlakuan dengan tiga kelompok (kontrol, zinc 20 μM dan staurosporin 0,16 μM). Selanjutnya dilakukan isolasi RNA dan elektroforesis RNA untuk mengetahui keutuhan RNA. Terakhir dilakukan qRT PCR yang kemudian datanya dianalisis secara statistika.Hasil: Ekspresi Bax, Bcl-2 dan VDAC1 pada galur sel kanker prostat (PC-3) yang diberi perlakuan zinc mengalami penurunan dibandingkan dengan kontrol (tidak diberi perlakuan). Akan tetapi penurunan ekspresi tersebut tidak bernilai signifikan karena nilai p > 0,05 (nilai signifikansi Bax = 0,309; nilai signifikansi Bcl-2 = 0,236; nilai signifikansi VDAC1 = 0,437). VDAC1 mempunyai korelasi yang signifikan (p < 0,05) dengan Bax (p = 0,01) dibandingkan dengan Bcl-2 (p = 0,118).Kesimpulan: Terjadi perubahan ekspresi pada setiap gen (Bax, Bcl-2 dan VDAC1) pada galur sel kanker prostat yang diberi perlakuan zinc dengan yang tidak diberi perlakuan, akan tetapi tidak bernilai signifikan. VDAC1 mempunyai korelasi yang bermakna dengan Bax dan mempunyai korelasi yang tidak bermakna dengan Bcl-2.

ABSTRACT

Background: Prostate cancer is the most common cancer in men. Cancer occurs due to loss control of cell proliferation and apoptosis thus continuously proliferating cells without cell death. Apoptosis is regulated by specific proteins including Bcl-2 family proteins and channel proteins. The development of prostate cancer requires the transformation of normal epithelial cells into malignant cells that lose the ability to accumulate zinc. One of the main effects of zinc is to prevent the growth of prostate cancer cells by inducing apoptosis by facilitating the process of pore formation Bax that started apoptogenesis mitochondrial. In addition to Bcl-2 family, VDAC1 also plays an important role in the process of apoptosis. Some studies suggest Bcl-2 has close links with related VDAC1 apoptosis and pro-apoptotic protein Bax also directly interact with VDAC which then induces the release of cytochrome c from the mitochondrial membrane.
