体外研究
(In Vitro)

Naringenin is shown to inhibit the proliferation of HepG2 cells resulted partly from an accumulation of cells in the G0/G1 and G2/M phase of the cell cycle. Naringenin has been shown to induce apoptosis as evidenced by nuclei damage and increased proportion of apoptotic cells. Naringenin triggers the mitochondrial-mediated apoptosis pathway as shown by an increased ratio of Bax/Bcl-2, subsequent release of cytochrome C, and sequential activation of caspase-3[1]. Naringenin exposure significantly reduces the cell viability of A431 cells with a concomitant increase in nuclear condensation and DNA fragmentation in a dose dependent manner. Cell cycle study shows that naringenin induced cell cycle arrest in G0/G1 phase of cell cycle and caspase-3 analysis reveal a dose dependent increment in caspase-3 activity which leads to cell apoptosis[2].

体内研究
(In Vivo)

Naringenin supplementation causes a significant reduction in the amount of total triglyceride and cholesterol in plasma and liver. In addition, naringenin supplementation lowers adiposity and triglyceride contents in parametrial adipose tissue. Naringenin-fed animals show a significant increase in PPARα protein expression in the liver. The expression of CPT-1 and UCP2, known to be regulated by PPARα, is markedly enhanced by naringenin treatment[3]. Naringenin increases hepatic fatty acid oxidation through a PPARγ coactivator 1α/PPARα-mediated transcription program. It prevents sterol regulatory element-binding protein 1c–mediated lipogenesis in both liver and muscle by reducing fasting hyperinsulinemia. Naringenin decreases hepatic cholesterol and cholesterol ester synthesis[4]. Naringenin inhibits TNF-α-induced VSMC proliferation and migration in a dose-dependent manner. Mechanistic study demonstrates that naringenin prevents ERK/MAPK and Akt phosphorylation while left p38 MAPK and JNK unchanged. Naringenin also blocks the increase of ROS generation induced by TNF-α[5].

Cell Assay
[1]

Naringenin is dissolved in DMSO and diluted in cell culture medium. The cells are rinsed with PBS and grown in a medium containing various concentrations of naringenin (50, 100, 150, 200, 250, 300 μM). The solvent DMSO treated cells are served as control. After 24 hrs of treatment, the medium is removed and replaced by another medium containing MTT. Cell viability is measured using the MTT assay[1].

Shanghai Jinpan Biotech Co Ltd has not independently confirmed the accuracy of these methods. They are for reference only.

Animal Administration
[3][4]

Rats: Semi-purified, powdered diets are prepared for concentrations of naringenin: 0, 0.003, 0.006, and 0.012% of diet. After 7 days of acclimatization, rats are assigned to one of four groups, with six animals per group, and fed semi-purified experimental diets for 6 weeks. The experimental diets contain 16% fat, 45.5% sucrose, and different naringenin concentration (0, 0.003, 0.006, or 0.012%) (Table 1). Rats have ad libitum access to food and water during the study period. Food intake and body weight are measured throughout the experiment[3].

Mouse: Eight- to 12-week-old mice are fed ad libitum a rodent standard diet or a high-fat diet containing 42% of calories from fat plus cholesterol (0.05% wt/wt). Naringenin is added to the Western diet at 1 or 3% (wt/wt). Ldlr−/− mice are fed for 4 weeks and C57BL/6J mice for 30 weeks. Food intake is measured daily, and body weight is measured biweekly. Mice are fasted for 6 h before intervention[4].

生物活性

Hoechst 33258 is a fluorescent dye that emits blue fluorescence when bound to dsDNA.

IC50: 51.31±4.56 μM (HeLa cell), 32.43±3.27 μM (HL60 cell), 15.42 ± 2.16 μM (U937 cell)[1]

体外研究
(In Vitro)

Hoechst 33258, a fluorescent compound with a head-to-tail bis-benzimidazole structure, is initially found to be cytotoxic against L1210 murine leukemia. Hoechst 33258 is evaluated for their cytotoxicity against human tumor cell lines, which are cervix carcinoma cell line (HeLa), Human promyelocytic leukemia cell (HL60) and U937 cell Line. The IC50 determined in the case of HeLa, HL60 and U937 is 51.31±4.56, 32.43±3.27 and 15.42±2.16 μM for Hoechst 33258, respectively[1]. The cytotoxic property of Hoechst 33258 is investigated on a panel of seven tumour cell lines of different histological origin and Madine-Darby canine kidney (MDCK) normal cells. All cell lines, except MCF-7, exposed to Hoechst 33258 exhibit GI50 from 84×10-6 to 191.5×10-6 mol/dm3. Under the same experimental conditions, Hoechst 33258, used as a binder reference compound, stops the cell cycle in S phase and G0/G1[2].

Cell Assay
[2]

Hoechst 33258 is prepared as stock solutions in highly pure water. Working solutions in a concentration range of 10-3-10-6 mol/dm3 are prepared prior to testing. Cytotoxic effects of Hoechst 33258 on tested cell lines are determined by the MTT assay. Cells are seeded in 96 micro well flat bottom plates at a concentration of 2×104 cells/mL and left overnight in the CO2 incubator allowing them to attach to the plate surface. Growing medium is replaced with compound supplemented or control medium and incubated for 72 h. Fresh medium with 5 mg/mL of MTT is added onto cells and incubated for 4 h at 37°C. Upon media removal, water insoluble MTT-formazan crystals formed inside the living cells are dissolved in DMSO and the absorbance at 570 nm proportional to the number of living cells is measured on an Elisa Microplate Reader. All experiments are performed at least three times in triplicates.The GI50 value, defined as the compound concentration (μM) leading to cellular growth inhibition by 50%, is calculated and used as a parameter to compare cytotoxicity among the compounds[2].

Leachianone A (0-20 μg/ml; 24-72 hours) exhibits a marked inhibition on the survival of HepG2 cells time- and dose-dependently manner, IC50 values are 6.9 μg/ml, 3.4 μg/ml and 2.8 μg/ml in cells with 24-, 48- and 72-hours treatment, respectively[1].
Leachianone A (10-30 μg/ml; 48 hours) indicates that at low concentration of LA (10 μg/ml), a substantial amount of cells is primarily in the early phase of apoptosis, at higher concentrations, induces a shift of the cell population to late apoptotic/ necrotic stage[1].
Leachianone A (10-30 μg/ml; 48 hours) decreases the precursor of caspase-3 in a dose-dependent manner, reduces the protein level of the pro-forms of upstream initiator caspases, caspases-8 and -9, decreases two downstream substrates, namely inhibitor of caspase-activated DNase(ICAD) and poly-ADP-ribose polymerase (PARP) in HepG2 cells[1].

PL553 is a specific and high-affinity fluorigenic substrate of Leukotriene A4 hydrolase (LTA4H), with a maximum absorption (λmax) of 210 nm and maximum emission (λem) of 410 nm. PL553 is a better LTA4H substrate than (l)-Ala-β-naphthylamide, and resistant to cleavage by other aminopeptidases, but can be cleaved by FAAH. PL553 (40 μM) is used to evaluate the potencies of known inhibitors toward LTA4H[1].

Kinase Assay
[1]

The ability of PL553 to discriminate LTA4H from APN enzymatic activity is tested using the (l)-Ala-β-naphthylamide and PL553 peptide substrates at 40 μM with either APN from porcine kidney (0.33 mU/mL) or recombinant human LTA4H (0.6 μg/mL). The enzymatic reactions proceeds for 1 h at 37°C in a final volume of 100 μL of 50 mM Tris-HCl (pH 7.4) or 50 mM Tris-HCl (pH 7.4) and 100 mM NaCl for APN or LTA4H, respectively[1].
