"ABSTRAK Koriokarsinoma merupakan keganasan yang sangat invasive berasal dari villi plasentra dan trofoblas. Mola invasif dan koriokarsinoma sangat reponsif terhadap kemoterapi dengan angka kesembuhan lebih dari 90 , yang memungkinkan tercapainya kesembuhan tanpa mengganggu fungsi reproduksi. Methotrexate MTX merupakan terapi yang sering digunakan pada beberapa keganasan dan merupakan protokol kemoterapi pada koriokarsinoma, namun MTX memiliki banyak efek samping. Berbagai penelitian pada setengah abad terakhir menunjukan fungsi penting nanokurkumin. Penelitian in vitro dan in vivo menujukkan perannya seperti anti inflamasi, pengeluaran sitokin, anti oksidan dan imunomodulator. Namun, sapai saat ini belum ada penelitian mengenai efek antikanker nanokurkumin pada koriokarsinoma. Penelitian eksperimental sederhana ini menggunakan uji Shapiro-Wilk, uji t sampel bebas, dan uji Anova One Way. Pada penelitianini, kami meneliti dan mebandingkan efek pemberian MTX atau kombinasi dengan nanokurkumin pada berbagai jalur sinyal. Pada penelitian ini, 4 kelompok sel BeWo diberikan kombinasi MTX dan nanokurkumin, 1 kelompok sel BeWo diberikan MTX sebagai control positif, dan 1 kelompok sel BeWo sebagai control negatif. Penelitian ini menunjukkan terdapat penurunan ekspresi telomerase, ekspresi NF- B, dan indeks proliferasi BrdU yang signifikan dengan pemberian kombinasi MTX dan nanokurkumin dibandingkan dengan MTX saja ABSTRACT Choriocarcinoma is a highly invasive malignant tumor arising from the placental villous and extravillous trophoblast. IM and CCA, which make up the majority of these tumors, are highly responsive to chemotherapy with an overall cure rate exceeding 90 , making it usually possible to achieve cure while preserving reproductive function. Methotrexate is a frequently used for the treatment of several malignancies and is part of the chemotherapy protocols used for choriocarcinoma; however, side-effect are common. Extensive research over the last half century has revealed important functions of nanocurcumin. Invitro and in vivoresearch has shown various activities, such as anti-inflammatory, cytokines release, antioxidant, and immunomodulatory. However, to date no study has been carried out to elucidate its anticancer activity of nanocurcumin in choriocarcinoma. In this study, we investigated and compared the effects of methotrexate alone or in combination with nanocurcumin on various signalling pathway. In this simple experiment stury, we used Saphiro-Wilk test, independent sample t test, and Anova One Way test to analize data. To study the potential cooperative effect of both against, 4 BeWo cell lines were treated with the combination of methotrexate and nanocurcumin, 1 BeWO cell line was treated with methotrexate alone as a positive control, and 1 BeWo cell line as a negative control. This study demonstrated significant reduction of telomerase activity, NF- B expression, and proliferation index BrdU of BeWo cell line treated with a combination of nanocurcumin and methotrexate compared with methotrexate alone. It shows that the effect of nanocurcumin and methotrexate are syngergistic suggest potential for the clinical use of methotrexate in combination with curcumin which will allow effective anticancer effect in choriocarcinoma.

"Latar Belakang : Kanker payudara merupakan salah satu penyebab kematian tertinggi akibat kanker pada wanita di Indonesia. Hal ini diantaranya disebabkan karena adanya resistensi terhadap terapi berlandaskan ROS seperti pada radioterapi maupun kemoterapi. Sel punca kanker payudara (cancer stem cells, CSCs) memiliki peran pada mekanisme resistensi ini. Penelitian terhadulu menunjukkan kemampuan CSCs untuk bertahan terhadap kondisi stress oksidatif pada pemberian rotenon. Karena itu, dalam penelitian ini dilakukan analisis terhadap faktor transkripsi NF-kB pada sel kanker payudara baik CSC maupun non CSC, terkait peran NF-kB dalam mempertahankan viabilitas sel kanker pada kondisi stress oksidatif.Metode: Penelitian dilakukan pada sel punca kanker payudara manusia (CD24-/CD44+) maupun non sel punca (CD24-/CD44-) yang diberi H2O2 dengan konsentrasi 1.1µM, 11µM, dan 110µM dengan kontrol sel yang tidak diberi H2O2. Penilaian dilakukan terhadap parameter ekspresi mRNA NF-kB, dan viabilitas sel. Uji statistik dilakukan menggunakan IBM-SPSS dengan nilai α < 0.05.Hasil: Pemberian H2O2 pada konsentrasi 11µM menunjukkan peningkatan yang signifikan pada ekspresi mRNA NFkB CSCs dibanding non CSCs (p<0.05). Sedangkan untuk hasil uji viabilitas pada seluruh konsentrasi H2O2 nampak bahwa CSCs mampu mempertahankan viabilitasnya dibandingkan dengan non CSCs yang mengalami penurunan viabilitas (p<0.05)..Kesimpulan: Kondisi stres oksidatif akibat pemberiaan H2O2 dapat meningkatkan ekspresi mRNA NF-kB pada CSCs sehingga viabilitasnya tetap dapat dipertahankan.

Introduction: Breast cancer is one of the highest causes of death from cancer in women in Indonesia. This is partly due to the resistance to ROS-based therapies such as radiotherapy and chemotherapy. Breast cancer stem cells (cancer stem cells, CSCs) have a role in this resistance mechanism. Previous studies demonstrated the ability of CSC to survive oxidative stress conditions due to rotenone administration. Therefore, in this study an analysis was carried out on the transcription factor NF-kB in breast cancer cells, both CSCs and Non CSCs, related to the role of NF-kB in maintaining the survival of cancer cells under conditions of oxidative stress.

Methods: The study was conducted on human breast cancer stem cells (CD24-/CD44+) and non stem cells (CD24-/CD44-) which were given H2O2 at concentrations of 1.1µM, 11µM, and 110µM with control cells not given H2O2. Assessment was carried out on the parameters of NF-kB mRNA expression, and cell viability. Statistical tests were performed using IBM-SPSS with a value of α < 0.05.

Results: Administration of H2O2 at a concentration of 11µM showed a significant increase in the expression of NFk-B CSCs mRNA compared to non CSCs (p<0.05). As for the viability test results at all concentrations of H2O2 it appears that CSCs was able to maintain its viability compared to non CSCs which experienced a decrease in viability (p<0.05).

Conclusion: Conditions of oxidative stress due to administration of H2O2 can increase the expression of NF-kB mRNA in CSCs so that its viability can be maintained.

In this study, conditions of oxidative stress due to administration of H2O2 led to an increase in the expression of NF-kB mRNA in CSCs so that cell viability could be maintained."

"Stroke merupakan penyakit yang menyebabkan kematian nomor dua dan kontributor penyebab disabilitas tertinggi di dunia dengan jenis stroke iskemik menjadi penyebab umum stroke. Saat ini, terapi standar stroke yang disetujui oleh Food and Drug Administration (FDA) hanya recombinant tissue plasminogen activator (rtPA). Penelitian mengenai efektivitas terapi rtPA menunjukkan rtPA memiliki tingkat keberhasilan untuk sembuh sepenuhnya hanya sebesar 35%. Oleh karena itu, terapi restoratif dikembangkan untuk penanganan stroke salah satunya terapi berbasis sel menggunakan sekretom dari mesenchymal stem cells (MSC). Dalam patofisiologis stroke, berbagai cascade reaksi molekuler internal sel memiliki peran yang kompleks. Contoh faktor yang terlibat dalam cascade molekuler tersebut adalah Protein kinase B (AKT) sebagai faktor penunjang survivability sel, dan Nuclear factor-kappa B (NF-kB) sebagai faktor pengaktif jalur inflamasi. Dalam penelitian ini, profil ekspresi gen tersebut diteliti dari sel punca MSC yang berasal dari Macaca fascicularis dengan diberikan perlakuan prakondisi hipoksia oksigen 3% selama 48 jam. Tingkat ekspresi mRNA gen tersebut diinvestigasi dengan metode RT-qPCR. Hasil uji ekspresi gen menunjukan peningkatan mRNA gen protein AKT1 dan penurunan mRNA gen protein NF-kB pada MSC prakondisi hipoksia. Hal tersebut menunjukkan potensi sekretom prakondisi sebagai terapi restoratif yang ditunjukkan dari perubahan profil ekspresi gen yang mengarah pada survivability cell.

Stroke is the second leading cause of death and the highest contributor to disability worldwide, with ischemic stroke being the most common type. Currently, the only FDA-approved standard therapy for stroke is recombinant tissue plasminogen activator (rtPA). Research on the effectiveness of rtPA therapy indicates that it has a full recovery success rate of only 35%. Consequently, restorative therapies, including cell-based therapies using secretomes from mesenchymal stem cells (MSCs), are being developed for stroke treatment. In the pathophysiology of stroke, various internal cellular molecular cascades play a complex role. Examples of factors involved in these molecular cascades include Protein kinase B (AKT), which supports cell survivability, and Nuclear factor-kappa B (NF-kB), which activates inflammatory pathways. In this study, the gene expression profiles of these factors were investigated in MSCs derived from Macaca fascicularis, subjected to hypoxic preconditioning with 3% oxygen for 48 hours. The mRNA expression levels of these genes were analyzed using the RT-qPCR method. The results showed an increase in AKT1 protein mRNA expression and a decrease in NF-kB protein mRNA expression in hypoxia-preconditioned MSCs. These findings indicate the potential of hypoxia-preconditioned secretomes as restorative therapy, as evidenced by changes in gene expression profiles that promote cell survivability."

Introduction: Polycystic ovary syndrome (PCOS) is a common reproductive problem in women at reproductive age, but until now aetiopathogenesis of PCOS has not been fully understood. The objective of this study was to analyse interrelationship between proliferation of ovarian follicular granulosa cells, CYP19A1 expression and polymorphism at codon 680 of FSHR towards the etiology of PCOS.

Methods: Observational analytic in the form of cross-sectional study was used in this research. The study was carried out between 2011-2014 at the Department of Biology, Integrated laboratory of Faculty of Medicine University of Indonesia and Yasmin clinic at the Cipto Mangunkusumo Hospital. A total of 142 subjects (66 patients with PCOS and 76 patients without PCOS) were involved in this study. Granulosa cells for culture were obtained from ovarian follicular fluid and total RNA was isolated from the cells. DNA samples were extracted from peripheral blood. Granulosa cell proliferation index was determined by counting under a phase-contrast microscope. CYP19A1 expression was measured by qRT-PCR, whereas polymorphism at Asn680Ser FSHR was performed by RFLP.

Result: Cell proliferation index and CYP19A1 mRNA expression levels in the granulosa cells of the PCOS group was significantly lower than non-PCOS (p < 0.05). There was no significant difference found in Asn680Ser FSHR genotype distribution between PCOS and non-PCOS group (p > 0.05). Based on Asn680Ser FSHR genotype variation, no significant difference was found between basal FSH hormone levels in the PCOS and non- PCOS group (p > 0.05) and FSHR genotype variation did not correlate with granulosa cell proliferation index between PCOS and non-PCOS group (p > 0.05). Moreover, there was no correlation between the granulosa cell proliferation index with aromatase mRNA expression levels (p > 0.05).

Conclusion: Cell proliferation index and CYPA1 expression of granulosa cells in PCOS group were lower compared to the non PCOS group although no correlation was found between the two parameters. Asn680Ser FSHR genotype did not correlate with individual susceptibility to PCOS. FSHR genotype variation did not correlate with basal FSH levels and granulosa cell proliferation index between PCOS and non-PCOS."

Introduction: Proliferation activity, collagen synthesis, and hydration of the skin will decrease with the process of aging, therefore, skin looks dull, sagging, and dry. Aquaporin-3 (AQP3) is a key protein that plays a role in keratinocyte proliferation and hydration, recently becomes the target of innovation development of anti-aging cosmetic moisturizer. This research aims to analyze a combination of two natural ingredients, Centella asiaticaethanolic extractand chitosan nanoparticles (EECA + NPK) to increased proliferation fibroblast cell and keratinocyte, synthesis type I and III collagen, and the expression of AQP3 in vitro.Methods: Microculture Tetrazolium Test was conducted to analyze the proliferation of fibroblast and keratinocyte. The synthesis of type I and III collagen in fibroblast were analyzed using Ezyme Linked Immunosorbent Assay (ELISA) kit (COL1A1 and COL3A1) after the exposure of CAEE + CNP in several concentrations for 24, 48, 72 hours and compared to Retinoic acid (RA). The expression of AQP 3 on fibroblast and keratinocyte was analyzed using antibody anti-aquaporin 3 ab125219 immunocytochemistry technique, then quantitively analyzed using Image-J software.Results: CAEE+ CNP increased the proliferation of fibroblas optimal result at 6.25mg/mL concentration and the proliferation of keratinocyte increased 1.5 time than control, optimal result at 3.125 mg/mL concentration, statistically were not significant different with RA.CAEE + CNP increased the synthesis collagen type I optimal after incubated for 72hours and the synthesis collagen type III optimal 48 hours, statistically were not significant different with RA.Using antibody anti-aquaporin 3 ab125219 immunocytochemistry examination indicated CAEE+ CNP increased the expression of AQP 3 on fibroblast and keratinocyte, optimal results at 12.5 mg/mL and 3.125 mg/mL respectively after 24 hours exposure.Conclusion: CAEE + CNP increased the proliferation of fibroblast and keratinocyte, synthesis of type I and III collagen, and the expression of AQP3 in fibroblast and keratinocyte;Introduction: Proliferation activity, collagen synthesis, and hydration of the skin will decrease with the process of aging, therefore, skin looks dull, sagging, and dry.
