Abstract

Glioma merupakan tumor otak primer yang cukup sering ditemukan di Indonesia di antara keganasan otak lainnya. Penderita glioma mempunyai angka harapan hidup yang rendah dikarenakan seringnya mengalami resistansi terapi. Hipoksia merupakan salah satu faktor yang mempengaruhi respons terapi radiasi. Penelitian ini menganalisis ekpresi mRNA HIF-1?, sebagai petanda jaringan hipoksia, pada glioma derajat rendah dibandingkan dengan glioma derajat tinggi. Sampel terdiri dari 15 jaringan glioma derajat rendah, 6 jaringan glioma derajat tinggi, dan 21 sel lekosit dari penderita glioma sebagai kontrol sel normal. Ekspresi relatif mRNA HIF-1? ditentukan secara kuantitatif dengan menggunakan Real Time RT-PCR. Hasil penelitian menunjukkan bahwa ekspresi mRNA HIF-1? pada glioma derajat tinggi lebih tinggi dibandingkan dengan glioma derajat rendah, namun tidak bermakna secara statistik. Hal yang menarik yaitu ditemukan peningkatan ekspresi mRNA HIF-1? dengan nilai yang bervariasi pada 73 % sampel glioma derajat rendah dibandingkan dengan sel lekosit sebagai kontrol sel normal. Begitu juga pada glioma derajat tinggi ditemukan peningkatan mRNA HIF-1? dengan nilai yang bervariasi pada 100% sampel. Dengan demikian, dapat disimpulkan bahwa terdapat variasi derajat hipoksia pada glioma derajat rendah dan derajat tinggi yang mungkin mempengaruhi keberhasilan terapi radiasi.Kata kunci: Glioma, mRNA HIF-1?, hipoksia

Abstract

Introduction Despite many health benefits from dietary fiber, inadequate intake is prevalent among elderly population. This study aims to obtain the pattern of fiber intake in different socio-demographic backgrounds among elderly in Jakarta area, Indonesia and its’ associated factors. Methods: A cross-sectional study was conducted among elderly aged > 60 years in 5 community health center across Jakarta province. A total of 126 elderly were interviewed using two non-consecutive 24-h dietary recall methods to obtain dietary intake data. Socio-demographic backgrounds on age, sex, education, income, marital status, and energy intake were assessed using structured questionnaire. Mann-Whitney or independent t-test was performed to measure the different of fiber intake in each socio-demographic variable. Linear regression test was performed to analyze the variables that associated with fiber intake. Results: Majority of 98.4% of elderly have total fiber intake <80% of Indonesian Recommended Dietary Allowance (RDA) with average intake of 6.6 g/d. Lower fiber intake was significantly found in females, widowed/separated, have lower education and income, and have inadequate energy intake. Factors associated with total fiber intake were income (adjusted β=0.20, p=0.01) and energy intake adequacy (adjusted β=0.65 p=0.00). Conclusion: Fiber intake among elderly in urban area is inadequate and the pattern was worse in the low socio-demographic settings. By this finding, it is important to give priority to the socially disadvantages group when formulating nutrition intervention policy in this population setting.

Abstract

Background: Obesity modulates oxidative stress and can be detected by examining malondialdehyde (MDA) serum levels. Flavonoids are natural bioactive ingredients that can be found in various types of vegetables and fruits that function as antioxidants to suppress that oxidative stress. Objective: This study aimed to determine the correlation between flavonoid intake and MDA serum levels in obese women of reproductive age. Methods: This cross-sectional study was conducted in Kendari, Indonesia from April to October 2021. The purposive sampling method was used to obtain 88 subjects who met the research criteria. Data were collected through interviews covering flavonoids intake using validated SQ-FFQ. Anthropometric measurements were performed to assess nutritional status, and laboratory tests were applied to determine MDA serum levels. Results: The average intake of flavonoids in the subjects was 142,26 ± 56,53 mg per day. Meanwhile, the average MDA serum level in the subjects was 2.16 mol/L, ranging from 1.09 nmol/ml to 6.71 nmol/ml. There was no significant correlation between total flavonoid intake and MDA serum levels in obese women of reproductive age (r=0,188, p=0,079). However, there was a weak correlation between the intake of flavonoid subclasses, namely flavan-3-ols/flavanols and MDA serum levels (r=0.325, p=0.002). Conclusion: We conclude that there was no correlation between total flavonoid intake and MDA serum levels. However, there was a correlation between flavan-3-ols/flavanols and MDA serum levels in the subjects.

Abstract

Latar belakang: Malondialdehida (MDA) merupakan petanda stres oksidatif yang merupakan produk akhir dari reaksi berantai proksidasi lipid. Untuk mencegah stres oksidatif, tubuh mensintesis katalase, suatu enzim antioksidan endogen yang mengkatalisis hidrogen peroksida (H2O2) menjadi air dan oksigen. Sampai saat ini kadar MDA dan katalase pada populasi usia lanjut (usila) masih memberikan hasil yang bervariasi dan kadar tersebut pada kelompok usia yang berbeda dalam populasi usila belum pernah dilaporkan. Dengan demikian, penelitian ini bertujuan untuk menganalisis profil kadar MDA dan aktivitas spesifik katalase pada plasma populasi usila berdasarkan peningkatan usia. Metode: Penelitian ini menggunakan 60 subjek wanita usila sehat yang tinggal di Jakarta. Subjek dibagi dalam 2 kelompok berdasarkan kategori usia, kelompok yang lebih muda (60 – 70 tahun) dan kelompok yang lebih tua (> 70 tahun). Kadar MDA dan aktivitas spesifik katalase dianalisis pada plasma dengan spektrofotometer. Hasil: Kadar MDA pada kelompok yang lebih muda (60 – 70 tahun) sedikit lebih tinggi dibandingkan kelompok yang lebih tua (> 70 tahun) namun tidak bermakna secara statistik. Selain itu, akitivitas spesifik katalase pada kelompok yang lebih muda lebih rendah bermakna dibandingkan dengan kelompok yang lebih tua. Kesimpulan: Tidak ada perbedaan bermakna kadar MDA plasma pada populasi usila. Namun, aktivitas spesifik katalase meningkat bermakna seiring dengan pertambahan usia.

In order to prevent oxidative stress, our body synthesizes catalase, an endogenous antioxidant enzyme that catalyzes hydrogen peroxide (H2O2) into water and oxygen. Until now, the level of MDA and catalase in aging population were still varied and those level at different age in elderly population has not been yet reported. Therefore, the purpose of this study was to analyse the profile of MDA level and catalase specific activity in plasma of elderly women based on increasing age. Methods: This research used 60 healthy elderly women as the subjects living in Jakarta. The subjects were divided into 2 groups based on age category, the younger group (60 – 70 years old) and the older group (>70 years old). MDA and specific activity of catalase were analyzed in plasma using spectrophotometer. Results: MDA level in the younger group (60-70 years old) was slightly higher than MDA levels in the older group (>70 years old) but it was not significant. Moreover, specific activity of catalase in the younger group was significantly lower than the older group. Conclusions: There was no difference in MDA level of elderly woman between younger and older group. However, catalase specific activity significantly increased with increasing age.

Abstract

BACKGROUND: In our previous study, we found higher cytoglobin (Cygb) expression in keloid than normal tissue. Cytoglobin is a new globin family protein which function is still being studied to date. The purpose of this research is to elucidate the function of Cygb in human skin keloid fibroblasts (KFs), especially its role in intracellular reactive oxygen species (ROS) levels.METHODS: The study was conducted on human skin KFs obtained from primary culture. Inhibition of Cygb expression was achieved by using siRNA targeting Cygb. We compared the relative expression of Cygb between treatment and control group, and its effect on intracellular ROS levels. Gene expression was measured using quantitative real-time polymerase chain reaction (qRT-PCR) while the ROS level counted by dichlorodihydrofluorescein diacetate (DCFHDA) assay.RESULTS: There was an increase in intracellular ROS levels in the small interfering RNA (siRNA) (+) Cygb group compared to control group (1.673 vs. 1.260; 1.773 vs. 1.393; 1.710 vs. 1.360; respectively). There is a negative correlation between Cygb expression and ROS level (p<0.05; r=-0.651).CONCLUSION: There is a negative correlation between Cygb expression and intracellular ROS levels, we suggest Cygb acts as a ROS scavenger in human skin KFs.KEYWORDS: skin keloid fibroblasts, cytoglobin, siRNA, ROS

Abstract

BACKGROUND: Glioblastoma multiforme (GBM) is a human malignant brain tumor which is arise from glial cells. Our previous study proved that GBM cells proliferation increased after treating by conditioned medium of umbilical cord-derived mesenchymal stem cells (CM-UCSCs). Cells proliferation is probably mediated by tumor necrosis factor (TNF)-α which could bind to membrane receptor and induce signaling pathway. Therefore, this research was intended to analyze the mRNA expression of TNF-α signaling pathway molecules on CM-treated GBM cells by measuring TNF receptor 1 and 2 (TNFR1 and TNFR2), TNFR associated factor 2 (TRAF2), nuclear factor kappa B (NF-κB) mRNA level, and TNFR2 protein level.METHODS: UCSCs and human glioblastoma T98G cells were cultured and harvested after 80% confluence. CM was prepared by growing UCSCs in serum alpha Minimum Essential Media (α-MEM) for 24 hours. Fifty percent concentration of CM-UCSCs was used to treat T98G cells for 24 hours. TNF-α level in CM-UCSC was detected using enzyme linked-immunosorbent assay (ELISA), while the expression of TNFR1, TNFR2, TRAF2 and NF-κB were detected using quantitative Reverse Transcriptase Polymerase Chain Reaction (qRT-PCR), and TNFR2 protein level was detected using sandwich ELISA.RESULTS: TNF-α level was detected in CM-UCSCs 4.4 pg/mL. Moreover, the expression of TNFR1, TNFR2, TRAF2 and NF-κB were significantly 1.4-fold, 4.9-fold, 5.6-fold, 1.8-fold respectively higher in T98G treated cells than control. TNFR2 protein level in T98G treated cells was 11.57 pg/mg protein higher than control.CONCLUSION: The expression of molecules involved in TNF-α signaling pathway were up regulated in T98G cells treated by CM-UCSCs.KEYWORDS: CM-UCSCs, TNFR1, TNFR2, TRAF2, NF-κB, T98G cells

Abstract

Cellular senescence is one of the defense mechanisms of cells against oncogenic signals by permanently stopping the proliferation of the cell. Senescence cells show a similar characteristic, one of them is senescence-associated secretory phenotype (SASP). SASPs secrete various components, divided according to the type of molecule secreted and based on their mechanism of action against target cells. The main components of SASP are pro-inflammatory mediators. SASP performs dual and contradictory roles, which concurrently provides beneficial effects such as tumor suppression due to the termination of proliferation, recruitment of immune cells, and tissue repair. On the other hand, SASP produces detrimental effects on cells undergoing the senescence process as well as cells in the surrounding environment by increasing tumorigenesis. This review article explains the various components of the SASP, the role of SASP in the inflammatory process, tumor suppression, and tumorigenesis.

Abstract

Effect of intermittent fasting 5:2 on plasma malondialdehyde levels in adult male employees with obesityBackground: Obesity is a major risk factor for various non-communicable diseases such as type 2 diabetes mellitus and cardiovascular disease. In obesity, the free radical product will be produced, such as malondialdehyde (MDA) which plays a role in the pathogenesis of various diseases. Intermittent fasting (IF) is an alternative way to reduce free radical levels in the body therefore it can prevent complications of obesity. However, the effect of IF on MDA level in an obese adult male in Jakarta has not been reported.Objective: The objective of this study was to determine the effect of IF on malondialdehyde levels in adult male employees with obesity in Jakarta.Methods: This study used a randomized controlled clinical trial. The subjects were men aged 19-59 years with a body mass index (BMI) ≥ 25 kg/m2, divided into fasting and control groups, each group consists of 25 subjects. Intermittent fasting 5:2 is calorie restriction up to 20-25% was done every Monday and Thursday, and not allowed to eat and drink during 14 hours of fasting. Before the intervention, both groups were given education about balanced nutrition. Association of intermittent fasting with MDA and catalase was analyzed by means of difference formula with a significance limit of 5%.Results: MDA levels post-intervention significantly decreased compared to the pre-intervention both in the fasting group [1,3(0,9-2) nmol/mL to 0,4(0,3-0,6) nmol/mL] and in the control groups [1,4(0,9-1,9) nmol/mL to 0,5(0,3-0,7) nmol/mL]. MDA level post-intervention in the fasting group was significantly lower (p<0,05) compared to the control group.Conclusions: Intermittent fasting 5:2 during 8 weeks can decrease MDA levels in adult males with obesity in Jakarta.

Abstract

Background: Insulin resistance is a condition in which insulin cannot take up glucose, increasing blood glucose. Elderly people are more exposed to insulin resistance, requiring dietary interventions that extend longevity. Trehalose, a naturally occurring sugar, showed potentially reduce insulin resistance which can be measured using the HOMA-IR (Homeostatis Model Assessment-Insulin Resistance) index. Objectives: This study aimed to assess HOMA-IR levels as a parameter of insulin resistance in old rats after giving trehalose sugar. Methods: Experimental research with 28 male Wistar rats (Rattus novergicus) was separated into 4 groups, the control group of young rats (Group A), the control group of old rats (Group B), a group of old rats that were given 2% Trehalose solution (Group C), and a group of old rats that given 2% sucrose solution (Group D) that observed for 8 weeks. Results: The results showed differences in HOMA-IR levels (p<0.001) between old and young subjects. The intervention in Group C was optimal in reducing levels of HOMA-IR (p<0.001) by 18.2% compared with the old control, while Group D increased levels of HOMA-IR by 14.3% (p<0.001) compared with the old control. The age of the subjects with HOMA-IR level is positively correlated (p<0.001; r=0.721) and the weight of subjects with the HOMA-IR level is also positively correlated (p<0.001; r=0.698), indicating that the older and the greater weight of subject resulting in the bigger of HOMA-IR value. Conclusion: Trehalose is effective in reducing HOMA-IR levels as a parameter of insulin resistance in old rats.
