N; and then 0 B from 59.1 to 64 min. The cells were then cleaned at a potential of 1000 mV for 1 min. The injection volume of the sample was 10 mL. The eluent was monitored by the Coulochem electrode array system (CEAS) with potential settings at 50, 200, 300, 400, 500, 600, and 700 mV. Data for Figures 2, 3, 4, 5, 6 was from the channel set at 50 mV of the CEAS.LC/ESI-MS MethodLC/MS analysis was carried out with a Thermo-Finnigan 18325633 Spectra System which consisted of an Accela high-speed pump, an Accela refrigerated autosampler, and an LTQ Velos ion trap mass detector (Thermo Electron, San Jose, CA) incorporated with heated electrospray ionization (H-ESI) interfaces. A Gemini C18 column (5062.0 mm i.d., 3 mm; Phenomenex, Torrance, CA) was used for separation of theaflavins and their potential metabolites at a flow rate of 0.2 mL/min. The column was eluted with 100 solvent A (H2O with 0.1 formic acid) for 3 min, followed bylinear increases in B (acetonitrile with 0.1 formic acid) to 70 from 3 to 48 min and to 100 B from 48 to 49 min, and then with 100 B from 49 to 54 min. The column was re-equilibrated with 100 A for 5 min. A Gemini C18 column (15063.0 mm i.d., 5 mm; Phenomenex, Torrance, CA) was used for separation of phenolic acids and their potential metabolites at a flow rate of 0.3 mL/min. The column was eluted with 100 solvent A (H2O with 0.1 formic acid) for 5 min, followed by linear increases in B (acetonitrile with 0.1 formic acid) to 100 from 5 to 15 min, and then with 100 B from 15 to 20 min. The column was reequilibrated with 100 A for 5 min. The LC eluent was introduced into the H-ESI interface. The negative ion polarity mode was set for the H-ESI source with the voltage on the H-ESI interface maintained at approximately 4 kV. Nitrogen gas was used as the sheath gas and auxiliary gas. To detect the theaflavins and their metabolites, optimized source parameters, including ESI capillary temperature (300uC), capillary voltage (?0 V), ion spray voltage (3.6 kV), sheath gas flow rate (30 units), auxiliary gas flow rate (5 units), and tube lens (?20 V), were tuned using authentic TFDG. To detect the phenolic acids and their metabolites, optimized source parameters were tuned using authentic EHop-016 cost gallic acid. These parameters include ESI capillary temperature (300uC), capillary voltage (?0 V), ion spray voltage (3.6 kV), sheath gas flow rate (35 units), auxiliary gas flow rate (15 units), and tube lens (?0 V). The collision-induced dissociation (CID) for H-ESI was conducted with an isolation width of 2 Da and normalized collision energy of 35 for MS2 and MS3. Default automated gain control target ion values were used for MS, MS2, and MS3 MedChemExpress STA-4783 analyses. The mass range was from 50 to 1000 m/z for detection TFs and their metabolites, from 50 to 400 m/z for detection phenolic acids and their metabolites. The mass resolution was 0.6 amu FWHM. Data acquisition was performed with Xcalibur version 2.1.0 (Thermo Electron, San Jose, CA).Author ContributionsConceived and designed the experiments: SS CJ SAI. Performed the experiments: HC SH JRG.

Chemical and biological data contain information about various characteristics of compounds, genes, proteins, pathways and diseases. Thus a wide spectrum of data mining methods is used to identify relationships in these large and multidimensional datasets and to generate predictive models with hig.N; and then 0 B from 59.1 to 64 min.
