Objectives: Medicinal plants and herbs are used in combination in Ayurveda and folklore medicine as they exhibit good cytotoxic activity. In the present study, the antioxidant, phytochemical, and cell proliferation activity of the combined crude methanolic extract of Ficus religiosa and Ficus benghalensis leaves were investigated.Methods: Antioxidant activity was performed by 2, 2-diphenyl-1-picryl-hydrazyl-hydrate (DPPH) and hydrogen peroxide methods, and the presence of the phytochemicals was screened using the gas chromatography–mass spectrometry. The extract was further evaluated for its cell proliferation activity against cancer cells using the mitochondrial reduction assay. Antioxidant property of the extracts was measured using the DPPH, hydrogen peroxide, and ferric-reducing antioxidant power assay, respectively, using the UV spectrophotometer.Results: The combined extract exhibited strong antioxidant potential in DPPH assay by increase in the percentage of inhibition with the increase in concentration. Similarly, the IC50 value of the methanol extract in peroxidase scavenging activity was 49.85 μg/mL comparatively lower than the ascorbic acid used as standard. The phytochemical analysis of the methanol extract showed the presence of nine phytoconstituents, which exhibit antioxidant and anticancer property. Mitochondrial reduction assay performed to evaluate the cell proliferation activity of the combined leave extract showed that increase in the concentration of the extract decreased the cell proliferation in the HeLa cell line.Conclusion: The results of present study show a possible synergistic activity of leaves against human cervical cancer.

This study is aimed at analyzing the anticancer properties of papaya leaf extract, specifically the inhibition of cell proliferation and apoptotic induction through nuclear factor kappa-light-chain-enhancer of activated B cells (NF-κB) and p53 pathways. Twenty-five mice (Mus musculus), aged 2 months and weighing 20–30 g, was injected with 0.5 mg dexamethasone for 7 days. The mice were then injected intracutaneously with 1 ml of HeLa cells (8 × 106 HeLa cells/microliter). The mice were divided into five groups (5 each): negative control (P1) (5% CMC-Na, sodium carboxymethyl cellulose), treatment II (225 mg/kg BW (body weight) papaya leaves methanol extract), treatment III (450 mg/kg BW), treatment IV (750 mg/kg BW), and treatment PV (2 mg alcohol anticancer drug). Papaya leaf extract treatments were applied for 2 weeks. Then, the tumor tissue was isolated for hematoxylin and eosin staining. Immunohistochemical imaging was used to detect Ki-67, caspase-3, NF-κB, and p53 expression. Further analysis was undertaken using the ImmunoRatio software program. The results indicated that administration of papaya leaf methanol extract significantly increased the expression of NF-κB and p53 at a dose of 450 mg/kg BW. Our results also showed that the mice treated with 450 mg of papaya leaf extract per kg of BW (P3) had the largest increase of caspase-3 expression compared to the negative control group. Papaya leaf ethanol extract decreased the cancer cell proliferation index and increased apoptosis of cancer cells in animal models of cervical cancer; it may also work to increase NF-kB expression and expression of the p53 gene.

Objectives: The objective of this study was to investigate the activity of combination of hydrolyzed VCO (HVCO) and chitosan on NIH 3T3 cell proliferation activity, NIH 3T3 cell migration, COX-2 and VEGF protein expression. Design: In vitro cytotoxic assay was determined by MTT (MicrocultureTetrazoliumTehnique) assay, cell proliferation activity was measured by calculating cell viability incubated 24 hours, 48 hours and 72 hours, wound closure percentage was tested by scratch wound healing method, expression of COX-2 protein and VEGF protein were measured by immunocytochemical method. Interventions: The variable that was intervened in this study was the concentration of HVCO and chitosan. Main Outcome Measures: The main measurements carried out in this study were the absorbance value of HVCO and chitosan which was converted into viability cell, proliferation activity, percentage of wound closure, and percentage of COX-2 and VEGF protein expression. Results: Cytotoxic activity of HVCO and chitosan resulted the best concentration at 31.25 μg/ml, scratch wound healing assay from a combination HVCO and chitosan resulted the best migration of fibroblast cells at a ratio of 1:1 with HVCO 62.5 μg/ml and chitosan 62.5 μg/ml, combination of HVCO 62.5 μg/ml and chitosan 62.5 μg/ml (1:1) increased expression of COX-2 and VEGF. Conclusion: Combination of HVCO and chitosan could increase NIH 3T3 cell migration, COX-2 and VEGF protein expression. Combination of HVCO and chitosan had better wound healing activity in vitro than single use. Keywords: Rhizomucor miehei, viability, proliferation, migration, expression
