Osthole is a bioactive coumarin derivative and has been reported to be able to enhance bone formation and improve fracture healing. However, the molecular mechanism of Osthole in bone fracture healing has not been fully defined. In this study we determined if Osthole enhances bone fracture healing through activation of BMP2 signaling in mice. We performed unilateral open transverse tibial fracture procedure in 10-week-old C57BL/6 mice which were treated with or without Osthole. Our previous studies demonstrated that chondrocyte BMP signaling is required for bone fracture healing, in this study we also performed tibial fracture procedure in Cre-negative and Col2-Cre;Bmp2(flox/flox) conditional knockout (KO) mice (Bmp2(Col2Cre) ) to determine if Osthole enhances fracture healing in a BMP2-dependent manner...

Osthole is a natural coumarin isolated from Umbelliferae plant monomers. Previous research has indicated that osthole exerts a wide variety of biological effects, acting as anti-seizure, anti-osteoporosis and anti-inflammation. However, the regulatory effect and related molecular mechanism of osthole in intrahepatic cholangiocarcinoma (ICC) remain unknown. In the present study, the authors found that osthole inhibited ICC cell lines in a dose- and time-dependent manner. Osthole also significantly induced mitochondrial-dependent apoptosis by upregulating Bax, cleaved caspase-3, cleaved caspase-9, and cleaved poly ADP-ribose polymerase expression, and by downregulating Bcl-2 expression...

Renal cell carcinoma (RCC) is a common urinary malignancy that is resistant to chemotherapy and radiotherapy. Osthole, a monomer compound extracted from a traditional Chinese herb, has potent anti-tumor effects on various types of cancer cells. However, the therapeutic effects of osthole on RCC remain unclear. In our study, osthole could suppress the proliferation and colony formation of two RCC cell lines, ACHN and 786-O cells, in a dose-dependent manner. Treatment with osthole resulted in a significant, dose-dependent increase in the expression of pro-apoptotic proteins (cleaved caspase-3 and Bax) and decreased expression of anti-apoptotic proteins (Bcl-2 and survivin), which were consistent with evidence of apoptotic nuclear morphology revealed by DAPI staining...

Alzheimer's disease (AD) is the most serious neurodegenerative disease worldwide and is characterized by progressive cognitive impairment and multiple neurological changes, including neuronal loss in the brain. However, there are no available drugs to delay or cure this disease. Consequently, neuronal replacement therapy may be a strategy to treat AD. Osthole (Ost), a natural coumarin derivative, crosses the blood-brain barrier and exerts strong neuroprotective effects against AD in vitro and in vivo. Recently, microRNAs (miRNAs) have demonstrated a crucial role in pathological processes of AD, implying that targeting miRNAs could be a therapeutic approach to AD...
