Abstract

BACKGROUND: Atherosclerosis, driven by inflammation and oxidative stress, increases the risk of coronary heart disease (CHD). Flavonoids in butterfly pea and roselle are known for their potent antioxidant and anti-inflammatory properties. While their individual effects on cardiovascular health have been studied, no studies have explored the combined impact on atherosclerosis biomarkers, including vascular cell adhesion molecules (VCAM)-1, intercellular adhesion molecule (ICAM)-1, and interleukin (IL)-6. Therefore, this study was performed to evaluate the synergistic effects of butterfly pea and roselle combination extracts (BPRCE) on these biomarkers.METHODS: A study with a post-test control group design using 36 male white rats was performed. The rats were randomly assigned to 6 groups; 1 group was fed with standard feed, while 5 groups were fed with a high-fat atherogenic diet (HFAD) to create atherosclerosis rat models. The HFAD rats were given either no treatment, sodium carboxymethylcellulose (Na-CMC), 300, 400, or 500 mg/kgBW BPRCE. Serum levels of VCAM-1, ICAM-1, and IL-6 of rats were measured using enzyme-linked immunosorbent assay (ELISA) methods.RESULTS: Increasing doses of BPRCE resulted in a significant reduction in VCAM-1, ICAM-1, and IL-6 compared to the other groups. The group with the highest dose, 500 mg/kgBW BPRCE, showed the greatest reduction of VCAM-1 level (32.73±3.57 pg/mL), ICAM-1 level (5.68±1.17 ng/mL), and IL-6 levels (21.49±4.62 pg/mL).CONCLUSION: Administration of BPRCE in atherosclerosis rats model reduces VCAM-1, ICAM-1, and IL-6 in a dose-dependent manner. This study showed that using BPRCE as a traditional remedy for preventing and treating CHD at an optimal dose of 500 mg/kgBW might be a potential future application in reducing atherosclerosis biomarkers.KEYWORDS: VCAM-1, ICAM-1, IL-6, butterfly pea, rosella, atherosclerosis

Abstract

BACKGROUND: The most influential susceptible gene associated with diabetes, transcription factor 7-like 2 (TCF7L2), has been observed in diverse populations. TCF7L2 influences type 2 diabetes risk through glucagon-like peptide 1 (GLP1) production. The presence of risk allele of TCF7L2 leads to the alteration of gene expression in pancreatic beta cells; however, how the mechanism is related with GLP1 remains unclear. This study was conducted to explore the variations of GLP1 increment and insulin secretion between individuals with and without diabetes risk allele of single nucleotide polymorphisms (SNPs) in TCF7L2.METHODS: A cross-sectional analytic study was conducted involving individuals subjects who harbored known variants of SNPs in the TCF7L2: heterozygote or mutant of rs12255372 (GT or TT), rs7903146 (CT or TT), rs10885406 (AG or GG); as well as control subjects with wild type of rs12255372 (GG), rs7903146 (CC), and rs10885406 (AA). Anthropometric parameters, blood glucose, insulin, and GLP1 were measured; and homeostasis model assessment-beta cell (HOMA-%B) index was calculated.RESULTS: The GLP1 increment response was higher in subjects carrying the diabetes risk allele (0.34±0.80 ng/mL) than those with the wild type (-0.04±0.57 ng/mL) (p=0.041). The HOMA-%B was reduced in subjects carrying the diabetes risk allele (71.64±24.72) than those with the wild type (103.23±68.00) (p=0.011). Among individuals carrying the diabetes risk allele, the likelihood of GLP1 increment with high response was twice as high (p=0.007), while the occurrence of low HOMA-%B was 1.47 more frequent (p=0.011).CONCLUSION: TCF7L2 polymorphisms were associated with the GLP1 increment response and reduced HOMA-%B, which might be potentially contributing to GLP1 resistance in patients with diabetes risk factors.KEYWORDS: diabetes risk, TCF7L2, GLP1, HOMA-%B

Abstract

BACKGROUND: Oxidative stress and trace elements in erythrocytes are linked to impaired nitric oxide that can lead to endothelial dysfunction in preeclampsia patients. The morphology of erythrocytes could also be affected by oxidative stress and trace elements. While the relationships between erythrocyte index, superoxide dismutase (SOD) activity, and oxidative stress in preeclampsia have been well established, less attention has been given to the erythrocyte trace elements and their role in disease progression. This study was performed to examine the erythrocyte trace element profile in women with preeclampsia, comparing it with controls. Additionally, it will explore the correlations between erythrocyte trace element levels, the erythrocyte index, and SOD activity.METHODS: A cross-sectional study was conducted involving 40 pregnant women consisting of those with severe preeclampsia and normotensive. Erythrocytes was isolated from blood samples, and analysis of erythrocyte SOD activity and trace elements were performed using the enzyme linked immunosorbent assay (ELISA) and inductively coupled plasma mass spectrometry (ICP-MS), respectively.RESULTS: Among 15 examined erythrocyte trace elements, the levels of ferrum (Fe), selenium (Se), and cadmium (Cd) were significantly lower, meanwhile, the levels of chromium (Cr) and lead (Pb) were significantly higher in preeclampsia subjects. Additionally, preeclampsia subjects exhibited smaller erythrocyte sizes compared to the normotensive subjects. The erythrocyte SOD activity was significantly elevated in the preeclampsia subjects than the normotensive subjects.CONCLUSION: Erythrocyte trace element levels of Fe, Se, Cd, Cr, and Pb were significantly altered in preeclampsia compared to normotensive controls. These findings suggest that these trace elements may serve as potential predictors for preeclampsia.KEYWORDS: preeclampsia, trace elements, antioxidant, oxidative stress, superoxide dismutase, erythrocyte index

Abstract

BACKGROUND: Preeclampsia is one of the common causes of maternal death in Indonesia. Many studies only focus on the diagnosis and pharmacological treatment of preeclampsia. However, predictors of preeclampsia need to be observed to add more focus on the etiology and prevention of preeclampsia. The imbalances of trace elements and fatty acids play an important role in preeclampsia. Therefore, this study was conducted to evaluate the status of trace elements and fatty acids in preeclampsia patients as predictors of preeclampsia.METHODS: A cross-sectional study was conducted in 3 hospitals, and involving 40 pregnant women classified into severe preeclampsia and normotensive groups. Trace elements and fatty acids were measured in serum and erythrocytes using Inductively Coupled Plasma and Gas Chromatography-Mass Spectrometry. Serum and erythrocytes fatty acid levels' cut-off value, sensitivity, and specificity were analyzed using Receiver Operating Characteristic (ROC) curve and Area Under the Curve (AUC) value.RESULTS: Serum selenium, manganese, and iron levels were significantly different in the preeclampsia group than in the controls (p<0.05). Of all the heavy metals, higher concentrations of cadmium, arsenic, lead, and mercury were found in preeclampsia groups compared to control. Linoleic acid showed the highest predictive value to increase severe preeclampsia with AUC of 0.8. The ratio of high omega-6/omega-3 increases the risk of preeclampsia.CONCLUSION: Selenium, manganese, iron, cadmium, arsenic, lead, and mercury levels are higher in the serum of preeclampsia patients. Almost all erythrocyte fatty acids were significantly higher in the control group compared to preeclampsia. Measurement of trace elements and fatty acids is needed as a predictor of preeclampsia. Erythrocyte fatty acids measurement is considered better than serum.KEYWORDS: trace elements, fatty acids, preeclampsia

Abstract

BACKGROUND: Colorectal carcinoma (CRC), the third most common malignant disease worldwide, is associated with estrogen receptor β (ERβ) and interleukin-6 (IL-6). ERβ is known to down-regulate IL-6 in prostate cancer, lung carcinoma, and CRC cell lines; however, its effect on human with CRC remains unclear. Therefore, this study was conducted to investigate the association between ERβ and IL-6 expressions with the clinicopathological features of CRC.METHODS: This was an analytic observational study using 40 paraffin blocks of CRC patients. ERβ and IL-6 expression was measured by immunohistochemistry (IHC) staining. The percentage of immunoreactive tumor cell per 1000 cells was manually recorded and tumor differentiation as well as tumor infiltration were determined. Tumor differentiation was graded according to the World Health Organization (WHO) 2010 criteria, while tumor infiltration was defined based on the American Joint Committee on Cancer (AJCC) 8th edition.RESULTS: Fifty percent of samples were well-differentiated CRC, and 57.5% samples were T3 infiltration tumors. IHC staining showed 35.5% of samples were positive for ERβ expression, while 70.86% were positive for IL-6 expression. There were negative correlation of ERβ expression with tumor differentiation (p=0.018; r=-0.371), but no correlation with tumor infiltration (p=0.836) were found. There was no correlation between ERβ expression with IL-6 expression (p=0.154).CONCLUSION: There is statistically significant correlation between tumor differentiation and ERβ expression, wherein improved tumor differentiation is linked to higher levels of positive ERβ expression. However, there is no discernible relationship between IL-6 and tumor differentiation. These findings suggest that while IL-6 was involved in the growth of the tumor, ERβ expression might have an impact on tumor differentiation.KEYWORDS: colorectal carcinoma, estrogen receptor beta, interleukin-6, cell differentiation

Abstract

BACKGROUND: Systemic lupus erythematosus (SLE) is an autoimmune disease characterized by inflammation. The pathogenesis of SLE involves key proteins, including B cell-activating factor (BAFF) and the ubiquitin enzyme A20, both serving as negative regulators of inflammation and contributing to B cell homeostasis. In this review, focused on interventions directed at BAFF and the A20 enzyme, utilizing monoclonal antibodies either independently or in conjunction with conventional therapy for SLE patients.METHODS: A literature search was conducted on the PubMed platform by combining various terms, including "B-cells activating factor", "TNFAIP3 protein (human)", "therapeutics" or "drug therapy", and "lupus erythematosus, systemic" (limited to the last 10 years). From total of 104 articles discovered in thr search, the total number of articles collected after being filtered was 27 articles.RESULTS: Clinical development and evaluation have been conducted regarding the use of appropriate therapy for SLE patients. Selective BAFF inhibitor has been tested in clinical trials as a blocking agent in BAFF receptor (BAFF-R) and signaling nuclear factor-kappaB (NF-κB) by A20 bindings to inhibit the activation of autoreactive B cells. Just like other antimonoclonal therapies, BAFF and the A20 enzyme can be used as therapeutic targets with a single use or combined with the standard therapy in patients with SLE. In addition, the use of BAFF and A20 also shown to have safe side effects in patients with SLE. CONCLUSION: BAFF protein and A20 enzyme present promising therapeutic targets for managing autoimmune diseases like SLE. Therapeutic interventions can be administered individually or in conjunction with standard treatments.  KEYWORDS: systemic lupus erythematosus, therapeutic targets, BAFF, A20

Abstract

BACKGROUND: Breast cancer remains the leading cause of cancer death worldwide. Migration and invasion of cancer cells are still crucial stages in the metastasis process, highlighting the urgent need for treatments that target both proliferation and metastatic progression. Curcumin and its synthetic analogue, pentagamavunon (PGV)-1, exhibit antiproliferative effects in breast cancer cells. However, the effects of combining curcumin and PGV-1 on cancer cell migration have not yet been explored. Therefore, this study was conducted to examine the antimigratory effects of curcumin and PGV-1 combination on 4T1 and T47D breast cancer cells.METHODS: Cytotoxicity effects of curcumin and PGV-1 were examined using an MTT assay to determine their effects on 4T1 and T47D cell viability. The antimigration activity was assessed using a scratch wound healing assay by measuring the closure of artificially created wounds on monolayer cells. Expression of matrix metalloproteinases (MMPs) that play a crucial role in cancer cell migration was analyzed using gelatin zymography to measure their enzymatic activities.RESULTS: The IC50 of PGV-1 and curcumin were 4.88 μM and 37.62 μM in 4T1 cells and 3.16 μM and 23.15 μM in T47D cells, respectively. Furthermore, combination of PGV-1 and curcumin effectively inhibited 4T1 and T47D cell migration. PGV-1 (0.5–2 μM) demonstrated superior antimigratory activity compared to curcumin (5–20 μM) by suppressing MMP-2 and MMP-9 expression in both cell lines. Significantly, curcumin was shown to synergistically enhance the antimigratory effects of PGV-1, leading to a further decrease in MMP-2 and MMP-9 expression. CONCLUSION: The combination of PGV-1 and curcumin may provide a promising antimigratory agent, potentially leading to enhanced antimetastatic strategies and more efficacious treatments for triple-negative and luminal breast cancer patients.KEYWORDS: antimigration, curcumin, luminal breast cancer, MMP-2, MMP-9, pentagamavunon-1, triple-negative breast cancer

Abstract

BACKGROUND: Neuroinflammation and immune dysregulation are frequently viewed as contributing factors of autism spectrum disorder (ASD). Brain-derived neurotrophic factor (BDNF) is involved in the maintenance of neuron viability, as well as in neuron differentiation. Meanwhile, Systemic Immune-Inflammatory Index (SII) and Systemic Inflammatory Response Index (SIRI) are basic hematological indices used to assess inflammation and immune status. Hyperbaric oxygen (HBO) is known to enhance cerebral blood flow and reduce inflammation, however, not many studies have observed the its effect on BDNF level, SII, and SIRI in ASD subjects; therefore, this study was performed.METHODS: Fifteen ASD subjects were involved in this study and received HBO therapy 10 times within a 2-week period. The HBO therapy was performed by letting the subjects got into an isolated chamber filled with 100% oxygen and 1.3 ATA pressure for 60 minutes. Pre- and post-therapy blood samples were taken from subjects. BDNF level was measured with Enzyme Linked Immunosorbent Assay (ELISA), while neutrophils, monocytes, lymphocytes and platelets were measured by hematology analyzer for the calculation of SII and SIRI.RESULTS: Post-therapy BDNF level was higher than pre-therapy (1.84 ng/mL vs. 1.46 ng/mL; p=0.039). The increased in BDNF suggested reduced neuroinflammation and enhanced connections between neurons. Both post-therapy SII (672.4 vs. 359.4; p=0.005) and SIRI (1.3 vs. 0.7; p=0.009) were significantly lower than pre-therapy indexes. Decreased in SII and SIRI signified a reduction in neuroinflammation.CONCLUSION: HBO therapy increases BDNF level, also decreases SII and SIRI in ASD subjects. These results suggest that HBO has an effect on neuroinflammation, specifically in ameliorating inflammation.KEYWORDS: autism spectrum disorder, BDNF, SII, SIRI, hyperbaric oxygen therapy

Abstract

BACKGROUND: Nigella sativa has been known for its neuroprotective properties, while propofol is an anesthetic induction drug that has been widely used in the treatment of traumatic brain injury (TBI). To determine the effectiveness of both active ingredients, it is necessary to compare their neuroprotective effects. This study was performed since not many studies have compared the effect of propofol and Nigella sativa seeds ethanol extract (NSSEE) or their combination on histopathological features in TBI cases.METHODS: Thirty male rat models were divided into 5 groups. Four groups received TBI induction with the methods of Feeney’s weight drop model, while another group (control group) did not receive TBI induction. Groups with TBI induction, later received no treatment, treatment with 500 mg/kg NSSEE orally, 10 mg/kg propofol intravenously, or a combination of NSSEE and propofol. After 8 days, rats were euthanized by cervical dislocation. Subsequently, a craniotomy was performed to obtain brain samples. The brain sample was placed in 10% neutral buffered formalin for histopathological examination, which includes brain hemorrhage, congestion, inflammatory cells, necrosis, apoptosis, and degeneration.RESULTS: The present study found that NSSEE showed greater efficacy in histopathological features (brain hemorrhage, congestion, inflammatory cells, necrosis, apoptosis, and degeneration) in rat models with TBI compared to propofol or a combination of propofol and NSSEE.CONCLUSION: NSSEE has superior potential compared to propofol and the combination of both in providing neuroprotection in TBI cases.KEYWORDS: traumatic brain injury, propofol, Nigella sativa seeds ethanol extract, histopathology, neuroprotective

Abstract

BACKGROUND: Tectona grandis Lf (TG) leaves are traditionally used in Indonesia for natural dyeing, and are gaining popularity as food colorants globally. However, their safety profile remains unclear. Acute toxicity studies reported no fatalities at doses up to 5000 mg/kg BW, histological analyses revealed inflammation and necrosis in the stomach, raising concerns regarding the long-term safety of TG leaf extract. Therefore, this study was performed to evaluate subchronic toxicity of TG leaf extract in both males and females Wistar rats.METHODS: TG leaf extracts were obtained by water extraction and extract powder was suspended in sodium carboxymethyl cellulose (Na-CMC). Male and female rats were administered TG leaf extract at doses of 0, 10, 20, and 40 mg/kg BW for 28 days, with a 14-days recovery phase in the satellite groups (as controls). Hematology profiles and biochemistry were analyzed using hematology analyzer and spectrophotometry. Histology analysis was performed to investigate TG effects on the organs.RESULTS: Hematological analysis revealed reversible reductions in hemoglobin, erythrocyte, and hematocrit levels, along with irreversible decreases in leukocyte and thrombocyte. While TG leaf extract did not significantly affect serum glutamic pyruvic transaminase (SGPT), serum glutamic oxaloacetic transaminase (SGOT), or creatinine levels, bilirubin levels increased, but remained within normal ranges. However, histopathological findings at 40 mg/kg BW revealed congestion and inflammation in the digestive organs, as well as neutrophil infiltration and congestion in metabolism-related organs, the lungs, liver, kidneys, and lymph nodes. These pathological changes persisted throughout the recovery period.CONCLUSION: TG leaf extract raises safety concerns, particularly at a dose of 40 mg/kg BW, as it induces irreversible organ pathology despite reversible changes in blood parameters.KEYWORDS: Indonesian Tectona grandis Lf, subchronic, toxicity, natural, food, colorants
