Abstract

BACKGROUND: ALDH1A1 and ALDH1A3, the most renowned isozymes of aldehyde dehydrogenase (ALDH)1, are important in regulating the pluripotency of human mesenchymal stem cells (MSCs) and cancer stem cells (CSCs). The study aimed to analyze the mRNA expression of ALDH1A1 and ALDH1A3 genes in adipose stem cells (ASCs) and umbilical cord stem cells (UCSCs) along with their correlations to Oct-4 mRNA expression. Additionally, the interaction between these proteins was also investigated using in silico study to confirm the pluripotency of both MSCs compared to human breast ALDH+ CSCs.METHODS: This research focused on determining mRNA levels of ALDH1A1, ALDH1A3 and Oct-4 in ASCs and UCSCs using one-step qRT-PCR. The data were then normalized to those in human breast CSCs and 18S rRNA. Oct-4 gene expression was also analyzed to determine the pluripotency of ASCs and UCSCs. The protein-protein interactions were in silico analyzed using String 9.1 software.RESULTS: Relatively, ALDH1A3 was expressed at similar level in ASCs and UCSCs, while ALDH1A1 expression level was significantly higher in ASCs compared to UCSCs. In contrast to ALDH1A3, the expressions of ALDH1A1 in both MSCs were significantly lower than breast CSCs similar to Oct-4 expressions, as also revealed by the in silico data showing the interaction between these proteins. This suggests the role of ALDH1A1 on pluripotency.CONCLUSION: ALDH1A1 and ALDH1A3 were distinctly expressed in UCSCs and ASCs, which might be associated with unique properties of ASCs and UCSCs. This study may contribute to further research in terms of implication of ALDH1A1 and ALDH1A3 expressions towards the properties of MSCs and its application in stem cell therapy.KEYWORDS: ALDH1A1, ALDH1A3, UCSC, ASC, breast ALDH+ CSC, Oct-4

Abstract

BACKGROUND: Umbilical Cord Blood (UCB) has been widely use as regenerative medicine due to the content of undifferentiated cell which have capability to do self-renewal and differentiation into various type of cell called stem cells. Recent studies show that UCB contains not only hematopoietic stem cell (HSC) but also others stem cell and progenitor cell such as endothelial progenitor cell (EPC) and very small embryonic-like stem cell (VSEL). It is beliefs that HSC and EPC shared the same progenitor. In this study, correlation between the cell number of HSC, EPC and VSEL is analyzed in umbilical cord blood as the source of stem cell for clinical application.METHODS: The cell number of HSC, EPC and VSEL is counted from cryopreserved UCB collected from 22 women delivered via cesarean section which already stored for more than 2 years in this study. Sample were incubated with antibodies such as cluster of differentiation (CD)34-phycoerythrin (PE)/CD45-fluorescein isothiocyanate (FITC), CD133/1 (anti-CD (AC)133)-antigen-presenting cell (APC) and, CD184 (C-X-C chemokine receptor (CXCR)4)-PE.Vio770 to detect the present of HSC, EPC and VSEL in UCB. Sample were analyze using flowcytometer BD FACS Canto II.RESULTS: The cell population of HSC and late-EPC is 0.009% and 0.01% of total cell in UCB. VSEL only represented 0.001% from total cell in UCB, showing the lowest number of cell population in UCB. The correlation between the cell number of HSC and EPC is r=0,483*, p=0.023) and between HSC and VSEL is r=0.510*, p=0.015.CONCLUSION: In this study, both EPC and VSEL have a significant positive correlation with HSC.KEYWORDS: stem cell, umbilical cord blood, endothelial progenitor, flowcytometry

Abstract

BACKGROUND: The leaf and fruit of Psidium guajava L. are potential for neutraceutical beverage especially for antidiabetic drink. The aims of this study were to determine the antidiabetic activity of aqueous extract of leaf (LE) and fruit (FE) from P. guajava.METHODS: Both extracts were investigated for their inhibitory effect on α-glucosidase activity in vitro. Their antioxidant activities were measured by 2,2-diphenyl-1-picrylhydrazyl (DPPH) free radical scavenging, ferrous ion chelating, reducing power and phosphomolybdate methods.RESULTS: The IC50 of LE, FEandacarbose as a positive control were 5.67, 428.00 and 823.99 μg/mL, respectively. The enzyme kinetic analysis indicated that LE inhibited α-glucosidase in a competitive inhibition type, similar to that of acarbose. Both extracts showed antioxidant activities, with LE showed stronger activities than FE in all methods. In DPPH method, IC50 of LE and FE were 74.77 and 843.84 μg/mL respectively, compared to 53.24 and 21.36 μg/mL for reference antioxidants butylated hydroxytoluene (BHT) and ascorbic acid (AA), respectively. In ferrous ion chelating activity, the IC50 were 147.07 and 2105.05 μg/mL for LE and FE, whereas ethylenediaminetetraacetic acid (EDTA) as a control sample was 66.50 μg/mL. In reducing power and phosphomolybdate methods, at different concentrations, the activities of LE, FE, and standard compounds showed the following order: AA > BHT > LE > FE.CONCLUSION: LE from P. guajava exhibited excellent inhibitory activity against α-glucosidase. In addition, LE had better antioxidant acivities than FE. This study can recommend the aqueous extract from P. guajava as a promising candidate for neutraceutical drink for prediabetic and diabetic patients.KEYWORDS: antioxidant, aqueous extract, α-glucosidase inhibition, guava, Psidium guajava L.

Abstract

BACKGROUND: Low back pain (LBP) mostly caused by disc degeneration, reflects to a tremendous of health care system and economy. More knowledge about these underlying pathologies will improve the opportunities that may represent critical therapeutic targets.CONTENT: Basic research is advancing the understanding of the pathogenesis and management of LBP at the molecular and genetic levels. Cytokines such as matrix metalloproteinases, phospholipase A2, nitric oxide, and tumor necrosis factor-α are thought to contribute to the development of LBP. Mesenchymal stem cells (MSCs) transplant to cartilage-like cells and secrete extracellular matrix and encourage nucleus pulposus (NP) cell activity inhibiting NP cell apoptosis, together with some chemical mediators such as cytokines and growth factors become a safe and effective new strategy for intervertebral disc degeneration (IDD) treatment and regeneration.SUMMARY: IDD occurs where there is a loss of homeostatic balance with a predominantly catabolic metabolic profile. A basic understanding of the molecular changes occurring in the degenerating disc is important for practicing clinicians to help them to inform patients to alter lifestyle choices, identify beneficial or harmful supplements, or offer new biologic, genetic, or stem cell therapies.KEYWORDS: low back pain, intervertebral disc, degeneration, nucleus pulposus, annulus fibrosus, extracellular matrix, genetic, stem cells

Abstract

BACKGROUND: The ureteral obstruction (UO) is the most common clinical disorders. This study was designed to investigate the renoprotective effect of estradiol in unilateral UO (UUO) and reversible UUO (RUUO).METHODS: Eighty-four ovareictomized Wistar rats were assigned into 14 groups. Group 1 was sham operated group. All the groups 2-14 were subject to UUO, however they received additional treatments. Group 2-4 received test substances (vehicle, 0.1 or 0.05 mg/kg of estradiol) and sacrificed after 3 days. Group 5-7 received test substances and after 3 days followed by RUUO (obstruction removal) and after one day post RUUO were sacrificed. Group 8-9 followed by RUUO after 3 days and simultaneously received estradiol and after one day post RUUO were sacrificed. Group 10-12 followed by RUUO after 3 days and simultaneously received test substances and after 3 days post RUUO were sacrificed. Group 13-14 received test substances followed by RUUO and received test substances again and after 3 days post RUUO were sacrificed.RESULTS: The estradiol reduced body weight significantly (p<0.05) in UUO, and the uterus weight (UW) increased significantly by estradiol (p<0.05). The increased serum levels of blood urea nitrogen (BUN) and creatinine (Cr), and kidney weight (KW) induced by UUO (p<0.05) were not attenuated by estradiol. Estradiol treatment did not alter the levels of BUN, Cr, KW, Cr clearance (CrCl), urine sodium excretion and urine flow when compared with control.CONCLUSION: Although the protective role of estradiol in cardiovascular system is well accepted, however our findings suggest that its protection during UUO or after RUUO in renal system cannot be certain.KEYWORDS: estradiol, ureteral obstruction, renal function, rat

Abstract

BACKGROUND: Chronic infection with high-risk type of human papillomavirus (HPV) can cause cervical cancer. Previous studies showed that multiple infections of HPV are found in cervical cancer caused by multiple HPV infections and the most common are HPV-16 and HPV-52. The origin of HPV-16 circulating in Indonesia varies. The purpose of this study was to explore the origin of multiple infections of HPV-52 and HPV-16 in cervical cancer by using a phylogenetic tree.METHODS: During July-November 2010, 100 women were diagnosed with cervical cancer in the Department of Obstetrics and Gynecology, Dr. Hasan Sadikin General Hospital, Bandung, Indonesia. Only 96 patients were involved in this study. Ninety-six samples of HPV deoxyribonucleic acid (DNA) were isolated from biopsied tissue of cervical cancer. Multiple infections of HPV genotypes HPV-16 and HPV-52 were confirmed by using the linear assay for HPV genotyping test. Afterward,HPV-52L1 gene was amplified by using self-designed primer. L1 gene was also sequenced and analyzed using phylogenetic program (MEGA6.06).RESULTS: The result of phylogenetic tree construction showed that isolated HPV-52 originated from multiple infections of HPV-16 and HPV-52 from cervical cancer patients in Bandung were in a subgroup with isolates originating from EU077219 Canada (America) and KT799980 southwest China (Asia). Isolate HPV-16 in one subgroup with isolates originating from KU951191.1 (Southwest China).CONCLUSION: L1 gene sequence from multiple infections isolated from HPV-16 and HPV-52 from cervical cancer patients in Bandung refers to the variation of L1 gene reported from Canada and southwest China. This proves that Indonesia’s HPV clusters are located in the strains found in America and Asia.KEYWORDS: multiple infections, HPV-16, HPV-52, L1 gene, phylogenetic
