"Epithelial Mesenchymal Transition (EMT) adalah salah satu mekanisme resistensi Sorafenib pada kanker hepatoseluler. Alfa Mangostin diketahui dapat menurunkan aktifitas jalur TGF-βpada hepatic stellate cells. Penelitian ini dilakukan untuk mengetahui pengaruh Alfa Mangostin pada Epithelial Mesenchymal Transition (EMT), HepG2 yang tahan terhadap Sorafenib melalui jalur TGF-β/SMAD. Sel lestari kanker hati, HepG2 dibagi menjadi enam kelompok perlakuan, yaitu kelompok DMSO 0,01%, Alfa Mangostin20μM, Sorafenib10μM, Sorafenib10μM+Sorafenib10μM, Sorafenib10μM-Alfa Mangostin20μM, dan Sorafenib10μM +Sorafenib10μM - Alfa Mangostin20μMselama 24 jam. Sel dihitung menggunakan trypan blue exclusion method. Kadar TGF-β medium diukur menggunakan ELISA. Ekspresi TGF-β,TGF-βRI, SMAD3, SMAD7, E-cadherin dan Vimentin diukur dengan qRT-PCR. Pemberian Alfa Mangostin pada sel HepG2 yang tahan terhadap Sorafenib dapat menurunkan jumlah sel hidup. Namun terdapat peningkatan ekspresi TGF-β, kadar TGF-β1 aktif, TGF-βRI, SMAD3, dan Vimentin serta penurunan ekspresi SMAD7 dan E-cadherin setelah pemberian Sorafenib dan Alfa Mangostin. Alfa Mangostin menurunkan jumlah sel hidup namun tidak menghambat EMT melalui jalur TGF-β/SMAD pada sel HepG2 yang tahan terhadap Sorafenib. Epithelial Mesenchymal Transition (EMT) is one of resistance mechanism through Sorafenib in hepatocellular carcinoma. Alpha Mangosteen is known to have reduced TGF-β/SMAD pathway in hepatic stellate cells. This research purpose is to explore the effect of Alpha Mangosteen on Epithelial Mesenchymal Transition (EMT) on human hepatoceluller carcinoma HepG2 cells surviving Sorafenib via TGF-β/SMAD pathways. Immortalized HCC cell line, HepG2 cells, were divided into 6 groups: DMSO0,01% group, Alpha Mangosteen 20μMgroup, Sorafenib10μM group, Sorafenib 10μM-Sorafenib10μM group, Sorafenib10μM +  Alpha Mangosteen 20μM group, dan Sorafenib10μM + Sorafenib10μM - Alpha Mangosteen 20μMgroup for 24 h. Cells were harvested and counted by trypan blue exclusion method. TGF-β medium concentration was evaluated by ELISA. Expression of TGF-β,TGF-βRI, SMAD3, SMAD7, E-cadherinand Vimentin measured by qRT-PCR. Alpha Mangosteen administration on HepG2 surviving Sorafenib cells reduced mean live cells. However, the expression of TGF-β, TGF-β1 active concentration, TGF-βR, SMAD3, and Vimentin were elevated. Alpha Mangosteen also decreased SMAD7 dan E-cadherin expression. Alpha Mangosteen reduced live cells but did not have effect on preventing EMT activation through TGF-β/SMAD pathways on HepG2 surviving Sorafenib cells. "

"AbstrakPURPOSE:Claudin-4 has been reported to function as a paracellular sodium barrier and is one of the 3 major claudins expressed in lung alveolar epithelial cells. However, the possible role of claudin-4 in bronchial asthma has not yet been fully studied. In this study, we aimed to elucidate the role of claudin-4 in the pathogenesis of bronchial asthma.METHODS:We determined claudin-4 levels in blood from asthmatic patients. Moreover, using mice sensitized and challenged with OVA, as well as sensitized and challenged with saline, we investigated whether claudin-4 is involved in the pathogenesis of bronchial asthma. Der p1 induced the inflammatory cytokines in NHBE cells.RESULTS:We found that claudin-4 in blood from asthmatic patients was increased compared with that from healthy control subjects. Plasma claudin-4 levels were significantly higher in exacerbated patients than in control patients with bronchial asthma. The plasma claudin-4 level was correlated with eosinophils, total IgE, FEV1% pred, and FEV1/FVC. Moreover, lung tissues from the OVA-OVA mice showed significant increases in transcripts and proteins of claudin-4 as well as in TJ breaks and the densities of claudin-4 staining. When claudin-4 was knocked down by transfecting its siRNA, inflammatory cytokine expressions, which were induced by Der p1 treatment, were significantly increased.CONCLUSIONS:These findings thus raise the possibility that regulation of lung epithelial barrier proteins may constitute a therapeutic approach for asthma."

"Tingginya angka mortalitas kanker ovarium (OC) disebabkan oleh pertumbuhan kanker yang cepat dan asimtomatik, serta belum ada faktor penanda untuk mengetahui progresivitasnya. OC epitelial (EOC) bersifat progresif dan agresif terkait kemampuan proliferasi yang tinggi. Salah satu faktor penentu progresivitas OC adalah angiogenesis yang diatur oleh VEGF yang dapat diinduksi oleh ligasi CD40. Adanya variasi genetik CD40 dan VEGF diduga berpengaruh terhadap progresivitas EOC (low dan high grade). Tujuan penelitian ini adalah menganalisis CD40 (rs1883832) dan VEGF (rs699947) yang dikaitkan dengan progresivitas EOC. Desain penelitian adalah potong lintang pada 65 EOC, 65 sehat dan 15 kontrol (jaringan kontralateral EOC). Analisis genotip menggunakan metode PCR ARMS dan analisis ekspresi mRNA menggunakan qPCR. Antara EOC dan kontrol terdapat perbedaan genotip dan alel CD40 dan VEGF, ditemukan ekspresi relatif mRNA CD40 dan VEGF pada EOC signifikan lebih tinggi, dibandingkan kelompok kontrol, ditemukan korelasi positif signifikan antara variasi genetik CD40 dan VEGF dengan ekspresi relatif mRNAnya, tidak ditemukan korelasi antara ekspresi relatif mRNA CD40 dengan VEGF. Variasi gen CD40 (rs1883832) dan VEGF (rs699947) menyebabkan ekspresi relatif mRNA yang berbeda dan signifikan pada kelompok low grade, high grade dan kontrol. Variasi kedua gen tersebut berhubungan dengan suseptibilitas individu terhadap EOC.

The high mortality rate of ovarian cancer (OC) is caused by grows quickly and asymptomatic and there are no tumor markers to determine its progresses. Epithelial OC (EOC) is progressive and aggressive due to its high proliferative capacity. One of the determinants of OC progression is angiogenesis, which is regulated by VEGF can be induced by CD40 ligation. Genetic variation of CD40 and VEGF is suspected to influence the progression of EOC (low and high grade). The aim of this study was to analyze the CD40 (rs1883832) and VEGF (rs699947) associated with EOC progression. The study design was cross-sectional in 65 EOC, 65 healthy and 15 controls (contralateral of EOC tissue). Genotyping analysis used PCR ARMS method and mRNA expression analysis used qPCR. Between EOC and control there are differences in CD40 and VEGF genotypes and alleles, it was found that the relative mRNA expression of CD40 and VEGF in EOC was significantly higher, than the control group, a significant positive correlation between genetic variation of CD40 and VEGF with their relative mRNA expression, no correlation was found between the relative mRNA expression of CD40 and VEGF. Gene variations in the CD40 (rs1883832) and VEGF (rs699947) led to different and significant relative expression of mRNA in the low grade, high grade, and control groups. Variation of these two genes is associated with individual susceptibility to EOC."
