To elucidate the effect of silibinin on lipid deposition and the potential molecular mechanism, the present study conducted in vivo and in vitro experiments. In the in vivo experiments, mice were randomly divided into control, high‑fat and silibinin groups, while HepG2 cells were randomly divided into control, palmitic acid intervention and silibinin intervention groups. The mRNA, protein and miR‑122 expression associated with hepatic lipid metabolism were detected in each group. The results demonstrated that silibinin reduced the triglyceride content, miR‑122 expression and the mRNA and protein expressions of fatty acid synthase (FAS) and acetyl‑CoA carboxylase (ACC). Silibinin increased the mRNA and protein expression of carnitine palmitoyl transferase 1A (CPT1A). In the present study, HepG2 cells cultured with palmitate were treated with silibinin following overexpression of micro RNA (miR) 122. The results demonstrated that the mRNA and protein expression of FAS and ACC was increased, while that of CPT1A was decreased. Therefore, it could be deduced that silibinin improved lipid metabolism by reducing the expression of miR‑122 and inhibiting the expression of miR‑122 may be a new therapeutic target to improve fatty liver disease.Programmed cell death protein‑1 (PD‑1)/programmed death protein ligand‑1 (PD‑L1) inhibitors for treatment of a various types of cancers have revolutionized cancer immunotherapy. However, PD‑1/PD‑L1 inhibitors are associated with a low response rate and are only effective on a small number of patients with cancer. Development of an anti‑PD‑1/PD‑L1 sensitizer for improving response rate and effectiveness of immunotherapy is a challenge. The present study reviews the synergistic effects of PD‑1/PD‑L1 inhibitor with oncolytic virus, tumor vaccine, molecular targeted drugs, immunotherapy, chemotherapy, radiotherapy
