Total protein was extracted from liver tissue, using RIPA protein lysis buffer containing 1 mM PMSF. 300 ng total protein were separated by 10% SDS-PAGE gel at 80 V for 1 h, transfered with polyvinylidenedifluoride (PVDF) membrane at 100 V for 1.5 h, blocked in 5% BSA (Solarbio, Beijing, China) and probed with appropriate primary antibodies against the target proteins. PTEN (Cat:#9188S), PI3 Kinase p85 (Cat:#4292S) anti bodies were purchased from Cell Signaling (Beverly, MA, USA). p-Akt (Cat:66444-1-Ig) and β-actin (Cat:20536-1-AP) anti bodies were purchased from Proteintech (Protein tech, Chicago, IL, USA). These were followed by incubation with Goat Anti-Rabbit immunoglobulin (Ig) G (H+L) (Cat:SA00001-2) (Protein tech, Chicago, IL, USA), and antigen-antibody complexes were visualized using the chemilucent ECL (TransGen Biotech, Beijing, China) detection system. The densitometric analysis conducted by Image J software 1.6.0 (National Institutes of Health, Bethesda, MD, USA) [37 (link),38 (link),39 (link)].

The human hepatoma cell line SMMC-7721 was plated in 6-well plates at a density of 5 × 10⁴ per well. After overnight culture, the TF at concentration of 1.0 mg/mL was added to the wells and cells were incubated for 48 h. Protein extracts were isolated from each group cells in using RIPA protein lysis buffer containing 1 mM PMSF. Total protein was separated by 10% SDS-PAGE, transferred with polyvinylidenedifluoride (PVDF) membrane, blocked in 5% BSA (Solarbio, Beijing, China), and probed with appropriate primary antibodies against the target proteins. PTEN, PI3 Kinase p85, p-Akt, andβ-actin antibodies were purchased from Cell Signaling (Beverly, MA, USA). These were followed by incubation with Goat Anti-Rabbit immunoglobulin (Ig) G (H + L) (Protein tech, USA), and antigen-antibody complexes were visualized using the chemilucent ECL (TransGen Biotech, China) detection system. The densitometric analysis was conducted by using custom Image J-based software, as reported earlier [19 (link), 20 (link)].
