Antiproliferative Action of Methanolic Petiole Extract of Eichhornia Crassipes on Human Prostate Adenocarcinoma Cell Line: An In Vitro Study

BACKGROUND

An increasing number of people are turning to herbal medicines in their search for innovative pharmaceuticals since they are effective treatments for a wide variety of conditions and traditional herbs are rich in bioactive chemicals. In this study, we looked at whether or not a petiole extract of Eichhornia crassipes preserved in methanol inhibited the proliferation of prostate cancer (PC3) cell lines.

MATERIALS AND METHODS

Lakes in Ezhikkara, Ernakulum, Kerala, were the source of E. crassipes. Soxhlet extraction was used to create the extract. 3-[4,5-dimethylthiazol-2-yl]2,5-diphenyltetrazolium bromide (MTT) assay was used to determine the cell viability of methanolic petiole extract at various concentrations. Mean and standard deviation was used to determine absorbance scores. Utilizing probit analysis, we determined the IC50 value. The descriptive statistics to measure the percent of viable cells along with the regression equation were calculated using SPSS.

RESULTS

It has been shown that the methanol extract significantly impacted PC3 cell lines' capacity to survive. It was also determined that increasing the medication concentration resulted in a decrease in cell viability. The percentage of living cells was measured after being exposed to methanol extracts at concentrations of 12.5 μg/ml, 25 μg/ml, 50 μg/ml, 100 μg/ml, and 200 μg/ml, and found to be 95.13, 85.88, 76.12, 64.33, and 53.62 percent, respectively. With IC50 values of 199.488 g/ml, it was shown that methanolic petiole extracts of E. crassipes are cytotoxic. Using probit analysis, we determined that the regression equation is y = -0.2051x + 90.915, with an R2 value of 0.893.

CONCLUSION

As a result of its chemotherapeutic properties, the E. crassipes petiole extract has the potential to be employed in therapeutic applications, with the ultimate goal of bettering prostate cancer management practices and clinical results by drastically lowering cell viability. The study's results may pave the way for fresh chemotherapeutic approaches to be developed for the treatment of androgen-independent prostate cancer.

Phytochemical screening and biological assays of ethanolic leaf extract of Senna rugosa

Abstract Senna rugosa (Fabaceae) is a common specie of the Brazilian territory, especially in the Cerrado biome. It is widely used in the popular medicine although not yet adequately investigated as to its phytoconstituents and pharmacological activities. In this study, the preliminary phytochemical analysis of ethanolic leaf extract of S. rugosa was performed and its cytotoxicity, antitumoral and antimicrobial activities (antibacterial, antifungal, anti-Trypanosoma and anti-Leishmania) were evaluated. The crude extract was analyzed in HPLC-DAD and fractions were also characterized using GC-MS and ESI-MS techniques. Results indicate phenolic compounds majority presence, including flavonol, anthraquinone and anthrones derivatives. Relative antimicrobial activities were detected against Staphylococcus aureus, Pseudomonas aeruginosa, Candida famata, Candida krusei and Candida tropicalis. As well as, a weak anti-trypanosomatids activity against M2269 strain and BH46 strain of Leishmania sp. A relative antitumoral activity was also identified but in counterpoint were also observed a toxicity in fibroblast cells (L929). Phytochemically, results provide evidence that phenolic compounds in S. rugosa leaves might be the responsible for its antimicrobial activity and cell toxicity inferred in our research.

Functional Genomic Investigation of the Molecular Biological Impact of Electron Beam Radiation in Lymphoma Cells

PURPOSE

The biological response of electron beam radiation (EBR) in tumors remains underexplored. This study describes the molecular biological and genomic impact of EBR on tumor cells.

METHODS

A mouse model bearing Dalton's lymphoma ascites cells was exposed to an 8-MeV pulsed electron beam, at a dose rate of 2 Gy/min using a microtron, a linear accelerator. The radiation-induced changes were assessed by histopathology, fluorescence-activated cell sorting, signaling pathway-focused reporter assays, and gene expression by microarray analysis.

RESULTS

EBR was found to increase apoptosis and G2-M cell cycle arrest with concomitant tumor regression in vivo. The microarray data revealed that EBR induced tumor regression, apoptosis, and cell cycle arrest mediated by p53, PPAR, and SMAD2/3/4 signaling pathways. Activation of interferon regulatory factor and NFkB signaling were also found upon EBR. Chemo-genomics exploration revealed the possibility of drugs that can be effectively used in combination with EBR.

CONCLUSION

For the first time, an 8-MeV pulse EBR induced genomic changes, and their consequence in molecular and biological processes were identified in lymphoma cells. The comprehensive investigation of radiation-mediated responses in cancer cells also revealed the potential therapeutic features of EBR.
