Abstract

Objective: We determine the utility of Prostate Specific Antigen (PSA) for predicting the presence of skeletal metastasis on Bone Scan (BS) in prostate cancer patients. Material & Methods: Retrospective analysis of medical records of 70 consecutive prostate cancer patients subjected to bone scan during the last 2 years was done. 5 cases were excluded due to the following reasons: Serum PSA not available, hormonal or other therapy given prior to serum PSA measurement, and/or Bone Scan, and symptomatic for bone metastasis. In remaining 65 cases, PSA value and bone scan were evaluated. Results: BS was found to be positive in 20/65 (31%) and negative in 45(69%) patients. 24 (37%) had serum PSA > 100 ng/ml, 25 (38.5%) had PSA of 20‐100 ng/ml and only 16 (24.5%) had PSA < 20 ng/ml. Conclusion: Serum PSA < 20 ng/ml have high predictive value in ruling out skeletal metastasis. Our data are in corroboration with results from previous studies that BS should be performed only if PSA > 20 ng/ml. Using this cut‐off, unnecessary investigation can be avoided. Avoiding BS asymptomatic in this group of patients would translate into a significant cost‐saving and reduction in their psychological and physical burden.

Abstract

Abstract Nanoparticles are non-viral vectors with biodegradability and controlled release abilities that are widely used in gene transfer. Nanoparticles are said to be able to effectively combine and concentrate DNA and RNA in products to be delivered to various cells. Based on changes in microRNA expression in cancer, delivery using microRNA nanoparticles from outside the body is expected to be one of the therapeutic solutions. Irradiated chitosan is assumed to undergo cutting off the main polysaccharide group to produce a smaller molecular weight compared to nonirradiated chitosan. The desired irradiation process to reduce chitosan particle size so that it has better absorption efficiency into the cell needs to be further evaluated including looking at its effect on the final potential zeta. Zeta potential is important to ensure that the nanoparticles are positive enough to be able to enter the negatively charged cell membrane. Chitosan used was irradiated at a dose of 5kGy mixed with 1: 1 nucleic acid ratio. The results of zeta potential measurements showed the highest zeta potential values ​​of 15.27 mV and 13.63 mV obtained in the formula with chitosan-microRNA composition only. The measurement result of zeta potential of irradiated chitosan nanoparticles decreases the surface charge of the particles, this can reduce the potential of nanoparticles for the process of delivery into the cell.

Abstract

MiR-21 has been linked to tumorigenesis, development, and metastasis in tumor pathogenesis. All human cancers, including breast cancer, have increased expression of MiR-21, which is the only miRNA that has increased expression. PTEN expression was found to be reduced in the majority of solid tumors, including breast cancer. Since lymph node metastatic factors, estrogen receptor status, tumor grade, and tumor node metastasis (TNM) all decreased PTEN expression, the PTEN expression profile may be a very useful prognostic marker in breast cancer. PTEN inhibits PIP3 (phosphatidylinositol 3,4,5-triphosphate) activity by having protein phosphatase and lipid phosphatase activity that is the polar opposite of PI3K (Phosphatidyl Inositol 3-Kinase). The aim of this research was to see how often miR-21 and mRNA PTEN were expressed at different stages of breast cancer and whether they could be used as prognostic markers. This type of research is an observational study with a cross-sectional design. The sample size of 43 people came from breast cancer patients. Analysis of miR-21 expression and mRNA PTEN using Real-Time qPCR. The results showed that miR-21 expression increased 1.32 times at an advanced stage compared to an early stage, while mRNA PTEN expression decreased 1.33 fold at an advanced stage compared to an early stage. According to the findings, miR-21 expression in the blood plasma of breast cancer patients was upregulated at an advanced stage compared to an early stage and downregulated mRNA PTEN expression. MiR-21 which is increased at an advanced stage has the potential to be a poor prognostic marker at the stage of breast cancer. The change in miR-21 expression can be a good candidate as a molecular prognostic marker and for future research the role of miR-21 in breast cancer progression will further enrich the scientific repertoire, especially in the health and clinical fields.

Abstract

Globally, prostate cancer (PCA) is the second leading cause of male cancer-associated mortality. Micro-RNAs (miRNAs) are small non-coding RNAs considered promising biomarkers for diagnosis, prognosis, and treatment options. A miR-141 expression is frequently dysregulated and influences the development and progression of PCA. This study aimed to identify miR-141 expression level as a marker to differentiate PCA from another prostate anomaly, especially in Yogyakarta. Formalin-fixed paraffin-embedded (FFPE) tissues for each three groups: benign prostatic hyperplasia/BPH, high-grade prostatic intraepithelial neoplasia/HGPIN, and PCA (n=7/group) were stored in a commercial clinical laboratory in Yogyakarta. The total RNA was extracted from FFPE sections using miRNeasy FFPE kit, followed by the quantification of miR-141-3p expression level by RT-PCR. The result showed that miR-141 relative expression level on PCA was higher than other groups and significantly different (P<0.05, Kruskal Wallis test). The mean of the miR-141 relative expression level of BPH, HGPIN, and PCA were 1.04±0.87, 6.44±7.8, and 7.06±8.83, respectively. The relative expression level of miR-141 can potentially be a prognostic biomarker in PCA and could differentiate aggressiveness in prostate anomaly, especially BPH, HGPIN, and PCA.

Abstract

Resistance to some cancer chemotherapeutic drugs has been identifed. One strategy to overcome that problem is by combining two or more of the drugs to get co-chemotherapeutic effects. A derivate chalcone, 3 - (4’-hydroxy-3’-methoxyphenyl)-1-phenyl-2-propene-1-on or para hydroxy meta methoxy chalcone (pHmMC), has been reported to have cytotoxic activity on some cancer cells through some pathways. The aim of this study was to investigate the effects of combinations of pHmMC and Doxorubicin (Dox) on the cytotoxicity, anti-proliferation, apoptosis, and the cell cycle of T47D (breast cancer cell-lines) in vitro. The cytotoxic and antiproliferative activity were determined by MTT (3-[4,5-dimethylthiazol-2-yl)-2,5 diphenyl tetrazolium bromide] assay. The combination index (CI) was used to determine the synergistic, additive or antagonistic effects of the combinations. Flowcytometry method was performed to determine the combination effects on the apoptosis and cell cycle. The results indicated that the combinations had a higher inhibitory effect on the cell growth compared to those of single treatments of pHmMC and Dox. All the doses used in the combinations were lower of the single doses at their IC50s. The results showed all the combinations gave synergistic (CI: 0.3 – 0.7) up to strong synergistic (CI: 0.1 – 0.3) effects. The synergistic effects of the combinations were due to increased apoptosis and induced cell cycle arrest in S and G2/M phases on the cancer cell lines.

Abstract

Ovarian cancer is a lethal disease. One of the problems faced by patients with ovarian cancer is the lack of symptoms in its early stages, which results in it only being detected when it is at an advanced stage. Therefore, there is an urgent need for biomarkers that can predict ovarian cancer precisely. The purpose of this study was to determine the expression of microRNA-21 as a predictive biomarker candidate in both early- and advanced-stage ovarian cancer. This was a cross-sectional study using the blood plasma of 21 healthy control subjects and 37 blood plasma samples from patients with ovarian cancer. Blood plasmas were collected, from which the RNA was isolated. Based on the RNA, the cDNA was synthesized and run through qPCR, the results of which were analyzed using the Livak method. The results showed an upregulation of microRNA-21 in the advanced stage by 2.14 fold compared with the early stage, and 6.13 fold compared with the healthy controls (p < 0.05). The upregulation of microRNA-21 in early-stage ovarian cancer was 2.86 fold compared with the healthy control subjects (p < 0.05). In addition, there was an increase in the expression of microRNA-21 in ovarian cancer by 4.14 fold compared with the healthy controls (p < 0.05). Based on these results, it can be concluded that the expression of microRNA 21 upregulated with the severity of the disease.
