Analysis Expression of ZIP1 and Caspase-3 Protein in Adenocarsinoma of the Prostate

Background: Carcinogenesis of adenocarcinoma of the prostate occurs due to dysregulation of zinc level within the cells. Intracellular zinc molecules influx is regulated by a transporter protein ZIP1, whose non-presence is predicted to inhibit apoptosis, thus leads to the development of prostate adenocarcinoma. Methods: This study was aimed to analyse the correlation of ZIP1 and Caspase-3 expression in prostate adenocarcinoma on its grading as represented by Gleason Score. This was a cross-sectional, retrospective analytical study on 31 Formalin-fixed, paraffin-embedded tissue that meets inclusion criteria. The specimen was stained using the immune-histochemistry technique for ZIP1 and Caspase-3. Protein expression of each case was counted using ImageJ analysis. Gleason score was acquired as secondary data from the cases' reports. The correlation of their expression with respect to Gleason score was analysed with Pearson's correlation using SPSS 11.5. Results: Mean expression level of ZIP1 and Caspase-3 in prostate adenocarcinoma were 35% and 33%, respectively. There was a significantly positive correlation between ZIP1 and Caspase-3 expression (r=0.379; p=0.018). However, their correlation was stronger in intermediate-grade group (r=0.73; p=0.01) and the correlation was much weaker in high-grade group (r=0.04; p=0.48). Conclusions: There was a positive correlation between ZIP1 and Caspase-3 expression in prostate adenocarcinoma.&nbsp

Peranan Gen HOXA10 terhadap Infertilitas Terkait Endometriosis

Endometriosis merupakan penyakit yang bersifat progresif, kronik, rekuren dan hingga saat ini etiologi pastinya belum diketahui. Gejala yang ditimbulkan endometriosis bervariasi mulai dari asimptomatik, nyeri pelvis hingga infertilitas. Beberapa studi terakhir di bidang biologi molekular menunjukkan adanya kemungkinan endometriosis sebagai penyakit epigenetik dan salah satu gen yang diketahui mengalami perubahan epigenetik adalah gen HOXA10. Gen HOXA10 berperan mengatur reseptivitas endometrium selama proses implantasi. Keberhasilan proses implantasi merupakan salah satu faktor yang berperan pada fertilitas wanita dan Gen HOXA10 memiliki peranan penting dalam proses implantasi tersebut. Metilasi gen HOXA10 mengalami peningkatan yang signifikan pada endometrium eutopik wanita yang mengalami endometriosis. Pada endometrium wanita yang mengalami endometriosis terdapat penurunan ekspresi HOXA10 yang signifikan dan hal tersebut mengindikasikan adanya gangguan pada reseptivitas uterus yang dapat berperan dalam menurunnya tingkat kesuburan. 

The effect of dadih in BALB/c mice on pro-inflammatory and anti-inflammatory cytokine productions

The normal microflora formed as commensal bacteria have roles in maintaining homeostasis in the intestine tract. The reduction in the amount and on the diversity of the commensal bacteria lead to gastrointestinal dysbiosis which increase number of pathogens, induce inflammatory and can drive to colorectal cancer. Probiotics can be used to prevent, regulate, and modulate immune response by triggering the development of pathogen-specific memory. Currently, many foreign probiotic products are available in the market that cause the domestic products are less well known. Dadih is an original probiotic’s products originally from West Sumatra, Indonesia. It is made from fermented buffalo milk containing lactic acid bacteria (LAB). The objective of the study was to investigate the effect of dadih pro-inflammatory and anti-inflammatory cytokine production. The study was conducted using male BALB/c mice aged 6-8 weeks with body weight (BW) 20-30 g. Mice were given dadih at doses of 112 mg/20g BW for eight weeks. The results indicated that LAB bacteria in dadih are coccus, Gram-positive bacteria with 3x107 colony-forming units (CFU) and dominated by Lactococcus lactis subsp. lactis. In addition, the increase of both the anti-inflammatory cytokines (IL-10) and pro-inflammatory cytokines (TNF-α and IL-1β) was observed. In conclusion, the dadih can be used to maintain the immune system of mice

Environmental Enrichment and Aerobic Exercise Enhances Spatial Memory and Synaptophysin Expression in Rats

BACKGROUND: Exposure to environmental enrichment has a positive effect on brain function, including improved cognition. Environmental enrichment has many aspects, including social interactions, object stimulations, and physical activities. Exercise and environmental enrichment can be considered to improve cognitive function with different underlying mechanisms. This study aims to compare the effects of environmental enrichment and aerobic exercise at both synaptic and whole-organism levels using synapyophysin as a measure of synaptic physiology and spatial memory as a measure of cognitive function.METHODS: A six-week in vivo experimental study on 15, 6-month old male Wistar rats randomly divided into three groups (n=5): aerobic group (A), enriched environment group (EE), and enriched with an aerobic or combined group (EEA). All rats were tested four times in the Water-E maze (WEM) task at weeks 0, 2, 4, and 6 of the study. We used immunohistochemistry to determine the synaptophysin expression in hippocampal CA1 region.RESULTS: Based on synaptophysin immunostaining, there were higher optical density scores for synaptophysin in hippocampal CA1 region following EEA, but there were no statistically significant differences between groups (ANOVA test, p>0.05). The spatial memory test showed there were significantly reduced travel time and total errors from the 2nd and 4th weeks in the EEA group, respectively (p<0.05).CONCLUSION: The combination of enriched environment and aerobic exercise seems to rapidly improve spatial memory and enhances the presynaptic protein, synaptophysin in hippocampal CA1 region.KEYWORDS: aerobic exercise, environmental enrichment, spatial memory, synaptophysin, Water-E maz

The effect of lunasin on inhibition of KI67, BCL-2 and C-MYC expression in azoxymethane and dextran sodium sulfate induced mice colon

Treatment of cancer using medicinal-plant based has been important due to minimal side effects, high efficiency and low cost. Lunasin from soybean is known as potential chemopreventive agent. This study aimed to study and investigate the proteins involved in the mechanisms of action of lunasin underlie its chemopreventive effects in Azoxymethane (AOM) and Dextran Sodium Sulfate (DSS) induced mice. A total 30 BLAB/c mice were separated into six groups. In five of the groups - a negative control group, positive control group, and three intervention groups - carcinogenesis was induced with AOM and DSS; the sixth group received no interventions. Lunasin were given in different doses of Low Dose Lunasin (75 mg/kgBW), Moderate Dose Lunasin (150 mg/kgBW), and High Dose Lunasin (200 mg/kgBW) to intervention groups. Immunohistochemistry was conducted to measure Ki67, C-myc, and Bcl-2 expressions from the distal colons of mice that had been sacrificed. The samples were microscopically assessed and photographed, and cell counts were performed using the Image J application. Further, the H-score method was used to quantify of Ki67, C-myc and Bcl-2 expressions. The results of this show that there is significant differences between the negative control and the intervention groups were found at the 75 mg/kgBW and 150 mg/kgBW (p < 0.05) lunasin dosage levels. This demonstrates that Lunasin inhibits proliferation and induces apoptosis in the colon mice induced by AOM and DSS

The Effect of Pegagan (Centella Asiatica (L.) Urban) Ethanol Extracts on Hippocampal PSD-95 Protein Expression in Male Wistar Rats

One effort to overcome the decline in memory function is through herbal medicine. Pegagan (Centella asiatica (L.) Urban) contain the active components of triterpenoid and flavonoids, has been known to be able to improve memory function. Synaptic plasticity is the basis of memory formation which is strongly influenced by synapse proteins such as PSD-95. Loss of PSD-95 protein can cause memory function decline. This study aims to determine the effect of 70% ethanol extract of pegagan toward PSD-95 protein expression on hippocampus of male Wistar rat. Eighteen male Wistar rats were randomly divided into 3 groups, 6 rats/group: group (1) given ethanol extract of pegagan with dose 300 mg / kgBW / day (CA300), (2) given ethanol extract of pegagan with dose 600 mg / kgBW / day (CA600), and (3) control group (K), given daily aquadest. All three groups were treated for 28 consecutive days. At the end of the treatment period, rats were decapitated and the hippocampus was isolated from the brain. Analysis of protein was done by immunohistochemical method. Statistical analysis was performed by One Way ANOVA parametric test followed by Post-Hoc Bonferroni. The results showed that there was no significant difference between group K and group CA300 (P = 0.123), whereas there were significant differences between CA600 group and K group and CA300 group (P = 0.000). From this research, it can be concluded that 70% ethanol extract of pegagan with dose 600mg / kgBW / day can increase expression of PSD-95 protein on hippocampus of male Wistar rat

Clinical, Molecular, and Histopathological Aspect of Primary Biliary Cholangitis

Primary biliary cholangitis (PBC), previously known as primary biliary cirrhosis, is an autoimmune liver disease which tends to be chronic and progressive in nature that is marked by the presence of cholangitis and small size biliary duct destruction which may cause cirrhosis or even liver failure. PBC incidence increases because PBC can now be diagnosed earlier and is due to the increasing survival rate of PBC patients. Diagnosis of PBC can be confirmed in asymptomatic state if in the indirect immunofluorescence (IIF) examination revealed AMA positive, and there is an abnormal liver function. Etiopathogenesis of PBC is multifactorial which involves genetic and environmental factors. Genetic factors which contribute to the incidence of PBC are HLA and non-HLA genes, while in the environmental factors, the triggering factors of PBC are bacterial infection and xenobiotic. Interaction of these factors causes the development of E2 subunit pyruvate dehydrogenase complex (PDC-E2) and antimitochondrial antibody (AMA) as the causing autoantigen of biliary duct desctruction in PBC, mediated by the immune system. PBC stage is divided into minimal, mild, moderate and severe. Ursodeoxycholic acid (UDCA) is the first line therapy for PBC, while obeticholic acid (OCA) and fibrate is used as the second line. Liver transplantation is the definitive therapy for PBC where disease progresses into the advanced stage, although the patients have received medical treatment

Centella asiatica ethanol extract increases hippocampal brain derived neurotrophic factor in male Wistar rats

Background Synaptic plasticity, which primarily takes place in the hippocampus, is the molecular basis of long- term memory formation. Brain derived neurotrophic factor (BDNF), a member of the neurotrophin family, plays a significant role in synaptic plasticity and memory formation. When BDNF is released, it binds to its receptor and activates various intracellular signal transduction pathways leading to synaptic plasticity. Several methods to improve memory function in humans have been studied, one of which is the use of herbal compounds, such as Centella asiatica (CeA), an herbaceous plant that has been used for improving memory. This study aims to examine the effects of CeA ethanol extract on BDNF protein expression in the CA1 hippocampal region in adult male rats. Methods A randomized experimental design was performed involving 18 adult male Wistar rats. The rats were randomized into three groups: one control/distilled water group and two groups treated with doses of CeA ethanol extract of 300 mg/kgBW (CeA300) and 600 mg/kgBW (CeA600), respectively. CeA ethanol extract was administered orally for 28 consecutive days with weekly weight-adjusted dose. After 28 days, the rats were decapitated, and the hippocampus was isolated from the brain. BDNF protein expression was assessed using immunohistochemistry. Data was analyzed using Kruskal-Wallis test and continued with post-hoc analysis. Results There was a significant increase in BDNF protein expression in the CeA600 group compared to the control group (p<0.001). Conclusion Administration of CeA ethanol extract increased BDNF protein expression in the CA1 hippocampal region of adult male rats
