Validity evaluation of a rat model of monoiodoacetate-induced osteoarthritis with clinically effective drugs.

Background: Knee osteoarthritis (KOA) is the most common type of joint disease in elderly people and is characterized by pain and dysfunction. Although the monoiodoacetate (MIA)-induced model is widely used as a rodent KOA model, it is important to acknowledge the inherent limitations of this model, as the MIA model develops complex pathological phases on a daily basis. An accurate understanding of this model and the selection of an appropriate time point according to the target for drug candidates can lead to the development of clinically effective drugs.

Synergistic anti-tumor effects of oncolytic virus and anti-programmed cell death protein 1 antibody combination therapy: For suppression of lymph node and distant metastasis in a murine melanoma model.

It is believed that oncolytic viruses (OVs) exert both direct anti-tumor effects by intratumoral injection as well as indirect anti-tumor effects by activating systemic immunity. In phase III clinical trials, OV and anti-programmed cell death-1 (aPD-1) antibody combination therapy showed no significant differences in overall survival and progression-free survival in patients with unresectable advanced melanoma. In the study, OVs can exert only indirect anti-tumor effects in non-injected, systemic lesions.
