MicroRNA-139 inhibits the proliferation and migration of osteosarcoma cells via targeting forkhead-box P2.

Aims: Osteosarcoma (OS) is the most common primary bone malignancy that affects adolescents. Although great attention has been paid to the diagnosis of and therapy for OS, the 5-year survival rate of patients with this disease remains poor. MicroRNAs are small non-coding RNAs involved in pathogenesis and progression of human malignancies.

Changes of rabbit meniscus influenced by hyaline cartilage injury of osteoarthritis.

Purpose: Osteoarthritis (OA) is a common disease in the elderly population. Most of the previous OA-related researches focused on articular cartilage degeneration, osteophyte formation and synovitis etc. However, the role of the meniscus in these pathological changes has not been given enough attention.

Transforming growth factor-1 promotes the transcriptional activation of plasminogen activator inhibitor type 1 in carcinoma-associated fibroblasts.

Carcinoma-associated fibroblasts (CAFs) play a pivotal role in promoting the growth, invasion and metastasis of tumor cells. However, to date little is known about the oncogenic mechanisms of CAFs. This study aimed to identify the microenvironmental factors involved in tumor development and progression directed by CAFs in liver metastases.
