Objective This present study aims to assess the effect of pirfenidone (PFD) on inhibiting fibroblast proliferation, migration or adhesion in vitro and reducing laminectomy-induced epidural fibrosis in vivo. Methods The effect of PFD on proliferation inhibition was evaluated with flow cytometry, CCK-8, EdU and western-blotting assays. Altered prope...

Post-surgery arthrofibrosis is one of the most restrictive factors in the development of intra-articular surgery and has presented tremendous obstacles for most orthopaedic surgeons. Tanshinone IIA (Tan IIA), a key active ingredient of Den-shen, has been used to treat fibrosis-related diseases, such as pulmonary, hepatic and myocardial fibrosis. In...

Objective: To investigate the effects of everolimus (EVE) on postoperative fibrosis in the knee joint and the potentially relevant signaling pathways. Methods: CCK-8 and flow cytometry assays were used to detect the effect of EVE on human fibroblast viability and apoptosis induction. IF and TEM were used to assess fibroblast autophagy. 3-methyla...

Background Excessive fibroblasts proliferation is believed as a major reason in the process of epidural fibrosis, which is known as a troublesome complication of lumbar laminectomy clinically. Mycophenolate mofetil (MMF) is a kind of immunosuppressant, previous studies had shown that it has the function of preventing fibrosis, but the role and mech...
Article
Intraarticular fibrosis following knee surgery is a troublesome complication and remains a challenging problem for clinicians. Artesunate (ART), a classical anti-malarial drug extracted from the Chinese medicinal herb Artemisia annua L, has been associated with some fibrosis-related diseases. However, its effect and underlying mechanism on knee art...

... Fibrosis is a progressive disease with excessive deposition of extracellular matrix (ECM) composed of fibrillar collagens, EDTA-fibronectin and SMA-stress fiber [27,[36][37][38][39]. Sustained fibroblast proliferation, activation and migration, generally identified as wound healing response, continually happen after tissue injury [40,41]. Healing by epidural fibrosis instead of regeneration may place burden on spinal cord and nerve root after spinal surgery [42]. ...
... Cryptotanshinone inhibited the expression of cyclin D1, and the phosphorylation of Rb in human rhabdomyosarcoma Rh30 cells induced cell cycle arrest at the G0/G1 phase [28]. In addition, previous studies [21,22,29] also showed that tanshinones could inhibit cell migration [30] through a wide range of signaling pathways, i.e., the HIF-1α-EMT pathway [31], STAT3-CCL2-EMT [32], PI3K/AKT signaling [33], and the PI3K and AMPK-mTOR signaling pathway [34]. However, little is still known about the roles and mechanisms of tanshinones, including dihydrotanshinone I in the regulation of cell adhesion and cell migration [33,[35][36][37][38][39]. ...
... RAD001 engages in the regulation of the PI3K/ AKT/mTOR pathway [68][69][70]. Next, we investigated the relationship between RAD001 and RTactivated PI3K/AKT/mTOR pathway by adding RAD001 after RT. The results revealed that treatment of RAD001 diminished the expression levels of PI3K, p-AKT, p-mTOR, p-S6K1, and p62, and elevated the LC3-II/LC3-I ratio and amount of acidic autophagic vesicles in CC cells. ...
... These viruses include herpes, human cytomegalovirus (HCMV) [10], rabies [76], etc. ART has been shown to have some anti-fibrosis efficacy [77] and can inhibit dermatitis due to its anti-inflammatory properties [78]. The activity of ART depends on its ability to regulate signalling pathways such as the P13K/AKT and P13K/AKT/mTOR [79]. ART reduces the concentration of glucose in the blood, and this is important in preventing the onset and progression of diabetes [80]. ...
