This study aimed to investigate research about cytotoxicity correlation level of Phaleria macrocarpa (Scheff) Boerl also known as Mahkota dewa leaves methanol extract against MCF-7 cell in vitroto investigate the relationship between them in the goal to investigate alternative low cost herbal medicine agents to fight breast cancer. Cytotoxicity properties of samples against MCF-7 breast cancer cell lines was performed by using the Microtetrazolium (MTT) assay against MCF-7 cell line. The correlation between concentration of crude and cytotoxic activity was interpreted by statistical analyses. The study showed that P. macrocarpa leaves extracts showed cytoxicity activity against breast cancer MCF-7 cell lines which IC50 concentration showed at 15 µg/mL Correlation between concentration of extract and cytotoxicity property (absorbance value) were founded in weak relationship (R = 0.372, R2 = 0.138). It could be effect of many different compounds in the P. macrocarpa leaves methanol extracts may cause the pharmacological interactions, so lower or higher concentration will be antagonistic effect on absorbance or cell viability. Further study on its mechanism pathway on revealing against breast cancer could be explored. Furthermore, the natural product derived from P. macrocarpa leaves methanol extracts have potential use as alternative drugs against breast cancer.

The aim of this research was to synthesize silver nanoparticle (NPP) by using Passiflora flavicarva (Markisa) fruit extract as detector of heavy metal. The NPP particles produced were determined by their optimum condition on the ratio of the volume of Passiflora flavicarva passion fruit extract to AgNO3 and the reaction time. The silver nanoparticles produced under optimum conditions will be tested for selectivity against several metals that are often present in the environment, once the selective metal is known then it can be sensitized to the metal using a UV-Vis spectrophotometer to determine the minimal concentrations that can be detected by the silver nanoparticles Formed. The results showed that Passiflora flavicarva passion fruit extracts could be used for the biosynthesis of NPP particles because they contain vitamin C and flavonoids capable of reducing Ag+ to Ag0 in the form of NPP. The optimal conditions for forming NPP particles are in the 1: 2 ratio with a 2 hour reaction time. From the results of selectivity test of NPP to some heavy metals that often exist in environment, it is known that NPP selective to mercury metal. It was found that selective mercury was followed by a sensitivity test with a UV-Vis spectrophotometer, with sensitive NPP up to a concentration of 6.7 ppm. From the results of this study it can be concluded that NPP particles formed can be used to detect mercury metal up to a minimum concentration of 6.7 ppm.

Digital image method in quantitative analysis usually uses one of the RGB primary color components (Red, Green, Blue), so that not all digital image data can be extracted. Then needed a method that can render the whole RGB values as variables in quantitative analysis are known as chemometric. This research aims to know the influence of the application of chemometric against the sensitivity of the digital image. Chemometry method used is the Principal Component Regression (PCR) and Partial Least Square (PLS) using Unscramber X software from Camo software, USA.. This method is applied for the quantitative analysis of Mercury (II) ion with silver nanoparticles (NPP) immobilization on filter paper indicator.

Published: July 2021

BackgroundHepatitis C virus-induced genes (HCVIGs) play a critical role in regulating tumor development in hepatic cancer. The role of HCVIGs in hepatic cancer remains unknown. This study aimed to construct a prognostic signature and assess the value of the risk model for predicting the prognosis of hepatic cancer.MethodsDifferentially expressed HCVIGs were identified in hepatic cancer data from the Gene Expression Omnibus (GEO) and The Cancer Genome Atlas (TCGA) databases using the library (“limma”) package of R software. The protein–protein interaction (PPI) network was constructed using the Cytoscape software. Functional enrichment analysis was performed using the Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathways. Univariate and multivariate Cox proportional hazard regression analyses were applied to screen for prognostic HCVIGs. The signature of HCVIGs was constructed. Gene Set Enrichment Analysis (GSEA) compared the low-risk and high-risk groups. Finally, the International Cancer Genome Consortium (ICGC) database was used to validate this prognostic signature. Polymerase chain reaction (PCR) was performed to validate the expression of nine HCVIGs in the hepatic cancer cell lines.ResultsA total of 143 differentially expressed HCVIGs were identified in TCGA hepatic cancer dataset. Functional enrichment analysis showed that DNA replication was associated with the development of hepatic cancer. The risk score signature was constructed based on the expression of ZIC2, SLC7A11, PSRC1, TMEM106C, TRAIP, DTYMK, FAM72D, TRIP13, and CENPM. In this study, the risk score was an independent prognostic factor in the multivariate Cox regression analysis [hazard ratio (HR) = 1.433, 95% CI = 1.280–1.605, P &lt; 0.001]. The overall survival curve revealed that the high-risk group had a poor prognosis. The Kaplan–Meier Plotter online database showed that the survival time of hepatic cancer patients with overexpression of HCVIGs in this signature was significantly shorter. The prognostic signature-associated GO and KEGG pathways were significantly enriched in the risk group. This prognostic signature was validated using external data from the ICGC databases. The expression of nine prognostic genes was validated in HepG2 and LO-2.ConclusionThis study evaluates a potential prognostic signature and provides a way to explore the mechanism of HCVIGs in hepatic cancer.
