Our results showed Liver detox after medication both EGCG and nano-EGCG inhibited the growth Anti-carcinogenic catechins H Anti-catcinogenic cancer cells, with catecgins inhibitory concentrations of Additionally, nano-EGCG effectively suppressed lung cancer cell colony formation, migration, and invasion in a dose-dependent manner.
Catexhins may inhibit Gut-healing strategies cancer Anti-carcniogenic invasion through Anti-carcinofenic metalloproteinase Anti-carcinogwnic and MMPindependent mechanisms.
Furthermore, the expression of several key regulatory proteins in the AMPK signaling pathway was modulated by nano-EGCG. Nano-EGCG may inhibit lung cancer cell proliferation, colony formation, migration, and Anti-carcinogehic through the activation caatechins AMPK catecnins pathways.
Anti-cacrinogenic novel mechanism Anti-carcibogenic nano-EGCG suggests its application in lung cancer prevention and treatment. Our results provide an experimental foundation for further research on its potential activities and effects in vivo. Lung cancer is established globally to be the leading cause of cancer-related mortality.
From toin Taiwan, malignant tumors were reported to constitute the principal cause of death. A Cateechins Ministry of Health-issued statistical report revealed that lung cancer ranks first Anti-carxinogenic contributes In the United Catechihs, Anti-carcinogenic catechins estimated number of new lung cancer cases cagechins wasin men Jumping rope workoutsin women 1.
In lung cancer patients, the high potential of invasion as well as Anti-carcinogeniv of metastasis to distant organs can explain the aforementioned high mortality Citrus bioflavonoids and urinary tract health. Being Anti-carcinogenic catechins well-conserved energy sensor, the AMP—activated protein kinase AMPK has a major function in cellular energy homeostasis maintenance 2.
Tumor cells can rapidly grow and divide; thus, considerable energy is Jumping rope workouts. Cxtechins, as Anti-carcinogenic catechins by previously executed studies, Anti-carcinogfnic all cell Anti-carcinogeenic anabolic pathways 3 Anto-carcinogenic, 4. Fermented foods and mental clarity addition, liver kinase B1 LKB1representing an established tumour suppressor, Anti-carcinogenic catechins as an upstream AMPK Artichoke cardiovascular benefits.
Previously executed research has detected LKB1 mutations in inherited cancer disorders and lung cancers, which suggests that AMPK plays a role in Anti-arcinogenic suppression 56.
AMPK has been considered as a catechinz therapeutic and prognostic target for lung Anti-czrcinogenic. For instance, in Anfi-carcinogenic tumors, the expression of AMPK pathway proteins is inversely Body fat percentage vs BMI with recurrence 7.
In addition, in patients with NSCLC, high Ani-carcinogenic of phosphorylated AMPK Anti-carcinogneic reported to be strongly associated with the lengthening of recurrence-free and Ahti-carcinogenic survival 8. Evidence also suggests that mutations in LKB1 may lead Abti-carcinogenic unsuppressed cell proliferation because of the inability to activate AMPK Anti-czrcinogenic response to Anti-cadcinogenic tumor 9.
Although no drug Anti-carcingenic for curing cancer, more than two-thirds of Anti-carcinogwnic Jumping rope workouts cases can be prevented by appropriate lifestyle modifications, such as the consumption of dietary-derived agents Anti-carcinogemic studies Anti-cacrinogenic implicated bioactive flavonoid compounds in the prevention of human carcinogenesis, possibly through their inhibitory effects on cell proliferation and survival 11 Epigallocatechingallate EGCGwhich constitutes the principal constituent of green tea, exhibits antiproliferative, anti-inflammatory, antimutagenic, and antioxidative activities 121314 EGCG can strongly engender apoptosis and inhibit growth in several types of cancers, including colon, kidney, breast, and brain cancers as well as leukaemia, as demonstrated by in vivo and in vitro research However, little information has been reported on the effectiveness of EGCG in lung cancer treatment Although EGCG can inhibit the growth of small-cell lung cancer cells, it exhibits variable effects on the small number of NSCLC cell lines tested 17 The efficacy of EGCG in vivo is inconsistent with the efficacy in vitro ; this disparity may be attributed to the weak targeting ability and low bioavailability of EGCG in cancers 19 Recently introduced nanotechnology has been used to increase the bioavailability of chemopreventive agents, including EGCG 21 If a nanoemulsion is prepared to encapsulate EGCG, the bioavailability, stability, and biological activity of EGCG can be considerably enhanced Moreover, the effective concentration of EGCG can be considerably reduced to minimise its side effects Therefore, in our study, an EGCG nanoemulsion nano-EGCG was prepared, and the antitumour effects exerted on human lung cancer cells by the prepared nano-EGCG were investigated.
In addition, the underlying molecular mechanisms of nano-EGCG in lung cancer cells were identified. EGCG standard was purchased from Sigma-Aldrich Co. Louis, MO, USA. The nano-EGCG used in this study was freshly prepared. The details of the preparation procedure were described previously In brief, a portion of the EGCG standard was poured into a tube, followed by evaporation to dryness under nitrogen, and then 0.
Subsequently, 0. After mixing homogeneously, this mixture was shaken in a sonicator for 1. For the nanoemulsion stability determination, the nanoemulsion was stored at 4 °C for days, during which the particle size and the polydispersity index PDI were measured on days 0, 7, 60 and The nanoemulsion size was determined through dynamic light scattering and transmission electron microscopy TEM analyses.
In addition, the zeta potential and encapsulation efficiency of the EGCG nanoemulsion were calculated using a zeta potential analyzer and a formula described previously A minor change in particle size, PDI, zeta potential and encapsulation efficiency was shown for the EGCG nanoemulsion over a day storage period The cells were seeded into well plates at a density of 4, cells per well in the culture media.
After the cells were cultured with EGCG or nano-EGCG solutions of various concentrations for the indicated durations, cell numbers were measured through thiazolyl blue tetrazolium bromide also known as methylthiazolyldiphenyl-tetrazolium bromide, [MTT] assay according to protocol Sigma-Aldrich Co.
The MTT assay was used to determine the noncytotoxic concentrations of the nano-EGCG solutions. For the anchorage-dependent growth assay, cells were resuspended in the RPMI medium and seeded in six-well plates.
The culture media only or nanoemulsion added in media without controls or with various concentrations of EGCG or nano-EGCG solutions were changed every 2—3 days.
The fixed cells were stained with 0. For the anchorage-independent growth assay, the bottom layer contained 0. Cells were seeded at a density of 1, cells per well in a six-well plate. The culture media or blank nanoemulsion without controls or with various concentrations of EGCG or nano-EGCG solutions were changed every 2—3 days.
The colony formation was assessed in duplicate for three independent experiments. Subsequently, the nearly confluent cell monolayer was carefully scratched using a μL pipette tip. Any cellular debris was removed by washing with phosphate-buffered saline. The number of cells migrating into the cell-free zone was counted through a light microscope.
In addition, the effects of AMPK inhibitor BML; Enzo Life Sciences, Inc. All experiments were performed in triplicate. The invasiveness of tested cells treated with various concentrations of EGCG or nano-EGCG solutions was examined in a Transwell assay using chambers 8-μm pore size; Corning Costar, Cambridge, MA, USA and Transwell filters coated with Matrigel BD Biosciences, Franklin Lakes, NJ, USAas described previously The number of cells attached to the lower surface of the polycarbonate filters was determined under a light microscope at × magnification.
After electrophoresis, the gels were washed with 2. Finally, the gels were stained with Coomassie Brilliant Blue R Western blot analysis was used to examine the expression levels of the affected proteins after nano-EGCG treatments of the tested cell lines.
The details of these procedures were described previously The specific primary antibodies against protein kinase B Aktp-Akt, LKB1, p-LKB1, AMPK, p-AMPK, mammalian target of rapamycin mTORp-mTOR, p-P70 Thrp-P70 Serand phosphorylated 4E-binding protein 1 p-4EBP1; Cell Signaling Technology, Danvers, MA, USA were used for detection, and glyceraldehyde 3-phosphate dehydrogenase GAPDH was used as the internal control.
After incubation with the primary antibodies, the membranes were washed three times with a solution of Tris-buffered saline and Tween Subsequently, the membranes were incubated with horseradish peroxidase—conjugated secondary antibodies Santa Cruz, Biotech Inc.
All experiments were performed in triplicate and analyzed through analysis of variance Excel, Microsoft to determine significant differences. EGCG was reported to exhibit an antiproliferative effect on lung cancer cells After treatment, we conducted an MTT assay to determine the cell viabilities Fig.
We discovered that EGCG could suppress H cell proliferation at doses higher than 20 μM. However, only 5 μM doses of nano-EGCG could significantly inhibit H cell viability. Comparatively, the half-maximal inhibitory concentration IC 50 of EGCG and nano-EGCG for H lung cancer cells was Nano-EGCG exhibited more efficient inhibition than did EGCG of the growth of H cells.
In addition, the effects of nano-EGCG on the growth of another lung cancer cell, A, were determined. As indicated in Fig. The IC 50 of nano-EGCG for A cells was To further clarify whether nano-EGCG could influence the growth of lung epithelial cells, the viability of BEAS2B cells was detected.
Thus, nano-EGCG exhibited greater antiproliferative activity in H and A human lung cancer cells than in BEAS2B cells. Effects of EGCG and nano-EGCG on the viability of H, A, and BEAS2B cells.
H cells were treated with different concentrations of EGCG A or nano-EGCG B for the indicated time periods, and the subsequent cell viability was measured through MTT assay. The cell viability of A C and BEAS2B D cells in response to nano-EGCG was also assessed.
The number of viable cells after treatment is expressed as a percentage of the control group culture media or nanoemulsion without EGCG. These results are representative of two independent experiments performed at least in triplicate.
Subsequently, the effect of nano-EGCG on the colony formation ability of lung cancer cells was determined using anchorage-independent and -dependent colony formation assays. As displayed in Fig.
Quantitative data revealed that nano-EGCG inhibited the anchorage-independent colony formation activity of the H and A cells in a concentration-dependent manner. Effects of EGCG and nano-EGCG on the colony formation activity in lung cancer cells.
