Abstract

Objective: To investigate the molecular pathway of the cytotoxic effect of SN-38 in human cervical cancer cell lines.Methods: Two human cervical cancer cell lines were treated with various concentrations of irinotecan for 24–72 hours and the sensitivity was analysed using the MTT assay. Apoptosis was further observed through microscopic examinations. The protein expression was determined using Western blot analysis.  Results: CaSki cells demonstrated the highest sensitivity to SN-38, whereas HeLa cells showed the lowest. In cervical cancer cells, SN-38 induced apoptosis through an intrinsic- and extrinsic-pathways. In addition, we showed that SN-38 downregulated the phosphorylation of Akt-mTOR pathways in CaSki cells, but not in HeLa cells. Interestingly, in HeLa cells, which were more suggestive of a resistant phenotype, pre-treatment with LY294002 and rapamycin inhibited activation of Akt-mTOR signaling and significantly enhanced the sensitivity of HeLa cells to SN-38. Conclusions: Irinotecan exerts its anti-neoplastic effects on cervical cancer cells by inducing apoptosis through caspase-cascade. Inhibition of Akt-mTOR, LY294002 and rapamycin, which is targeted to Akt-mTOR pathways, may sensitize irinotecan-resistant cervical cancer cells.Keywords: Akt-mTOR pathways anti-neoplastic drugs, cervix cancer cells, LY294002, rapamycin DOI: 10.15850/ijihs.v1n1.103

Abstract

Metode isolasi sel-sel mononuklear/mononuclear cells (MNCs) dari darah tali pusat (DTP) manusia secara konvensional menghasilkan tingkat kontaminasi sel eritrosit yang sangat tinggi. Oleh karena itu, tujuan penelitian ini adalah menilai perbedaan viabilitas dan kontaminasi sel eritrosit dalam populasi MNC DTP pada modifikasimetode isolasi yang kami kembangkan. Penelitian ini juga bertujuan untuk menguji fungsi dan karakteristik populasi MNCs dari DTP manusia sebagai dasar pembangunan bank darah tali pusat di Indonesia. Penelitian dilakukan di Departemen Obstetri dan Ginekologi RS Dr. Hasan Sadikin Bandung periode Januari–Oktober 2010. Isolasi MNCs dengan metode modifikasi (dinamakan modifikasi Unpad-Aster) yang menghasilkan 5,1x106 sel/mL memiliki tingkat kontaminasi sel eritrosit yang lebih rendah dibandingkan dengan metode konvensional. Morfologi sel yang dibiakkan dalam medium unrestricted somatic stem cells (USSCs) tampak seperti sel-sel yang adheren (menempel di dasar), berbentuk sel spindle, dengan cluster of differentiation-90 (CD-90) (antigen leukosit) dan cluster of differentiation-105 (CD-105) yang positif serta dapat berdiferensiasi menjadi sel neuron dan adiposit; sedangkan morfologi untuk cord blood-derived multipotent progenitor cells (CB-MPCs) tampak seperti sel-sel fibroblas dengan cluster of differentiation-45 (CD-45) (antigen hematopoetik) yang positif serta dapat berdiferensiasi menjadi sel neuron. Disimpulkan bahwa metode modifikasi Unpad-Aster memberikan tingkat kontaminasi eritrosit yang lebih rendah dibandingkan dengan metode konvensional. Sel mononuklear yang berasal dari darah tali pusat ini dapat berdiferensiasi menjadi sel-sel neuron dan adiposit.

Therefore, the aim of this study was to assess the differences of cell viability and erythrocyte contamination on the population of UCB MNCs in our modified isolation method. This study was also aimed to test the function and characteristic of human MNCs derived from UCB as the basis for the development of UCB banking in Indonesia. The study was conducted in Department of Obstetry and Ginecology >RS Dr. Hasan Sadikin Bandung in period of January–October 2010. The modified isolation method (namely Unpad Aster’s modification) yielded 5.1x106 MNC cell/mL has lower erythrocyte contamination level than conventional method. The morphology of MNCs cultured in unrestricted somatic stem cells (USSCs) medium looked like adhered cells (attached at the surface of culture flask), spindle-shaped cells with positive luster of ifferentiation-90 (CD-90) (leukocyte antigen) and cluster of differentiation-105 (CD-105) and could differentiate into neuronal cells and adipocytes. While the morphology of cord blood-derived multipotent progenitor cells (CB-MPCs) looked like fibroblast cells with positive cluster of differentiation-45 (CD-45) (antigen hematopoietic) and could differentiate into neuronal cells. In conclusions, the Unpad-Aster’s modified isolation method gives lower level of erythrocyte contamination compared with conventional method. Mononuclear cells derived from UCB could differentiate into neuronal cells and adipocytes.

Abstract

Objective: To analyze the role of selenium and glutathione peroxidase (GPx) in cervical cancer.Methods: Serum selenium concentrations and GPx activities of 19 women with cervical cancer along with their healthy counterparts (control group) were obtained. Selenium concentration were measured fluorometrically and GPx activities were measured spectrophotometrically based on the quantity of NADPH used in the reduction of glutathione. Results: The mean of serum selenium concentrations in cervical cancer group was significantly lower than that in the control group, 67.24±15 ng/mL and 77.05±12 ng/mL (p=0.03), respectively. The mean GPx activity in the cervical cancer group was also significantly lower than that in the control group, 128.18±38 ∆mmol NADPH/min/L and 148.9±23 ∆mmol NADPH/min/L (p=0.04), respectively. Multivariate analysis in the cervical cancer patients showed that the Fédération Internationale de Gynécologie et d’Obstétrique (FIGO) staging score (early vs. advanced) was inversely correlated with serum selenium concentration (p=0.027).Conclusions: Serum selenium concentration and GPx activity was significantly lower in the cervical cancer patients. Our results demonstrate that selenium and GPx activity may have an important role in the carcinogenesis of cervical cancer.

Abstract

Objective: To determine the role of protein-with-molecular-weight-53 (p53), burkit cell lymphoma 2 (Bcl2),  Fas ligand (FasL) mRNA, and vascular cell adhesion molecule 1 (VCAM-1), known as the apoptosis-related molecular pathway, in preeclamptic patients.     Methods: Observation on the correlation between the mRNA levels of p53, Bcl2 and FasL and VCAM-1 in 31 subjects at 28-42 weeks gestational age was performed in this study using the real time reverse transcriptase-polymerase chain reaction (RT-PCR).    Results: The results showed that p53 mRNA increased (>1.2350 ng/μL) in the preeclampsia group compared to the normal pregnancy group (p=0.010), Bcl2 mRNA was lower (≤0.9271 ng/μL) in the preeclampsia group than the control group (p=0.041). There was also a tendency of increased FasL mRNA expression (>0.5509 ng/μL) in the preeclampsia group compared to the normal pregnancy group (p=0.300). The level of VCAM-1 elevated (>890.08 ng/mL) in the preeclampsia group compared to the normal pregnancy group (p=0.001). In preeclampsia, the correlation between the Bcl2/p53 ratio and VCAM-1 was r=0.541 (p=0.002), whereas the correlation in normal pregnancy was r=0.099 (p=0.595).     Conclusions: There are correlations between the mRNA expression levels of p53 and Bcl2 as an intrinsic pathway of apoptosis along with the VCAM-1 levels in the incidence of preeclampsia. However, no correlation is found between FasL mRNA expression and the incidence of preeclampsia.Keywords: Bcl2, FasL, p53, Preeclampsia, VCAM-1DOI: 10.15850/ijihs.v2n1.273

Abstract

Objective: To analyze the effect of sitting and soaking therapy with the decoction of Anredera cordifolia on the perineal wound healing in postpartum period mothers.Materials and Methods: The research method used is the Quasi-Experiment with pretest-posttest control group design, a sample of 62 primiparous postpartum period mothers with 2nd-grade perineal rupture. The sampling technique used is purposive sampling to obtain 31 respondents treated by 31 respondents. The wound healing variable was observed using the REEDA scale. The characteristic analysis is tested using Mann-Whitney statistical test, while to test the effect analysis is tested using the Wilcoxon test.Results: The results of this study in the intervention group showed 52.71% was cured after getting treatment for perineal wounds sitting and soaking therapy with the decoction of Anredera cordifolia. On the other hand, in the control group, using only clean water shows 27.90% recovered. Analysis data effect of using the decoction of Anredera cordifolia 25% containing on perineal wound healing showed results with Wilcoxon Test with value (p<0.05).Conclusion: Based on this result there is an effect of sitting and soaking therapy with the decoction of Anredera cordifolia on perineal wound healing for postpartum mothers.
