RESUMEN
Background and aim: Cis-Diamminedichloroplatinum (II) (Cisplatin) is one of the most synthetic anticancer drug but have several adverse effects and one of them is acute ren failure. Cisplatin can induce nephrotoxicity occur via the toxic generation of reactive oxygen species (ROS). Black soybean (Glycine max L. Merr.) has been reported contain high levels of phenolics and anthocyanins that has antioxidant activity. This study aims to determine the effect of ethanol extract of black soybean (EEBS) against cisplatin-induced nephrotoxicity in rats. Experimental procedure: Cisplatin-induced nephrotoxicity rats treated with EEBS and the blood samples taken on days 0, 9, and 18. The effects of EEBS was evaluated by determining Interferon-γ (IFN-γ), Caspase-3 (Casp-3), and Interleukin-1ß (IL-1ß) expression using immunohistochemistry (IHC), blood urea nitrogen (BUN), Uric Acid (UA) content and catalase (CAT) content in the blood plasma with colorimetric assay kit. Results and conclusion: Based on the results, EEBS treatment had successfully reduced pro-inflammatory cytokines IL-1ß and IFN-γ, and improved physiological condition by lowering BUN and UA content while increasing CAT activity. No significant effect was found in Casp-3 expression. EEBS has potential to improve acute renal failure condition through inflammatory suppression and renal function improvement.
RESUMEN
Oxidative stress, the disrupted oxidation-reduction mechanism in our body, is caused by the excessive exposure of free radicals and the impaired antioxidant defenses that can accelerate skin aging. Antioxidants can be obtained from nature, which are available widely in therapeutic-rich plants, such as white saffron (Curcuma mangga Val., denoted as C. mangga). Although many pieces of evidence reveal that C. mangga contains an abundance of phenolic compounds and has antioxidative effects, its cosmeceutical potentials remain unclear. The present study aimed to disclose the unexplored antiaging potentials of C. mangga extract (CME) in oxidative stress-induced human BJ fibroblasts with a focus on collagen protection against pro-inflammatory mediators MMP1, MMP3, and MMP13. The oxidative stress-induced cells were treated with CME and curcumin at different doses. The results showed that treatment using CME (25 µg/mL) could maintain the collagen contents up to 18.45 ± 0.68 µg/mL in H2O2-treated fibroblasts (only ~26.63% reduction in collagen contents), while the figure for the negative control was the lowest (12.79 µg/mL), showing a significant reduction in collagen contents by 49.13%. In addition, the gene expression of pro-inflammatory MMPs arose significantly in BJ fibroblasts after oxidative stress induction using 200 µM H2O2, in which the expression for MMP1, MMP3, and MMP13 increased by 7.10, 38.96, and 2.69 times, respectively. Interestingly, CME treatment (100 µg/mL) could effectively inhibit MMP1, MMP3, and MMP13 gene expression by 3.65, 34.62, and 2.02 times, respectively. In conclusion, CME showed favorable antiaging activities in H2O2-treated human BJ fibroblasts as confirmed by the low levels of gene expression of MPP1, MMP3, and MMP13 after treatment with CME.
RESUMEN
Mesenchymal stem cells (MSCs) have unique properties, including high proliferation rates, self-renewal, and multilineage differentiation ability. Their characteristics are affected by increasing age and microenvironment. This research is aimed to determine the proliferation, characteristics and differentiation capacity of adipose tissue-derived (AT)-MSCs at many passages with different media. The cell proliferation capacity was assayed using trypan blue. MSCs characterization (CD90, CD44, CD105, CD73, CD11b, CD19, CD34, CD45, and HLA-DR) was performed by flow cytometry, and cell differentiation was determined by specific stainings. Population doubling time (PDT) of AT-MSCs treated with fresh frozen plasma (FFP) and non-FFP increased in the late passage (P) (P15 FFP was 22.67 ± 7.01 days and non-FFP was 19.65 ± 2.27 days). Cumulative cell number was significantly different between FFP and non-FFP at P5, 10, 15. AT-MSCs at P4-15 were positive for CD90, CD44, CD105, and CD73, and negative for CD11b, CD19, CD34, CD45, and HLA-DR surface markers. AT-MSCs at P5, 10, 15 had potential toward adipogenic, chondrogenic, and osteogenic differentiation. Therefore, PDT was affected by increased age but no difference was observed in morphology, surface markers and differentiation capacity among passages. Cumulative cell number in FFP was higher in comparison with non-FFP in P5, 10, 15. Our data suggest that FFP may replace FBS for culturing MSCs.
