UNLABELLED Prostate cancer has a proclivity to metastasize to bone. The mechanism by which prostate cancer cells are able to survive and progress in the bone microenvironment is not clear. Identification of molecules that play critical roles in the progression of prostate cancer in bone will provide essential targets for therapy. Ribosomal S6 protein kinases (RSK) have been shown to mediate man...

Purpose Bone is one of the most common sites of breast cancer metastasis, and population-based studies of patients with bone metastasis in initial metastatic breast cancer (MBC) are lacking. Materials and methods From 2010 to 2013, 245,707 breast cancer patients and 8901 patients diagnosed with initial bone metastasis were identified by Surveillance, Epidemiology, and End Results database of ...

Introduction: The aim of the present study was to evaluate the efficacy and safety profile of bone palliative therapy following administration of 153Sm-EDTMP in patients with intractable metastatic bone pain. Methods: Sixteen patients (9 male, 7 female) aged 29-80 years (57.3±16.7 years) with severe metastasis-related bone pain resistant to analgesic medications were enrolled in the...

Gentian violet (GV) is a cationic triphenylmethane dye, with potent antifungal and antibacterial activity. We recently reported that in vitro GV suppresses the differentiation of bone resorbing osteoclasts while stimulating the differentiation and activity of bone forming osteoblasts. Breast cancer is highly metastatic to bone and drives bone turnover that further promotes cancer engraftment an...

Osteoprotegerin (OPG) is a secreted member of the TNF receptor superfamily, which binds to the receptor activator of nuclear factor κB ligand (RANKL) and inhibits osteoclast activity and bone resorption. Systemic administration of recombinant OPG was previously shown to inhibit tumor growth in bone and to prevent cancer-induced osteolysis. In this study, we examined the effect of OPG, when prod...

OBJECTIVES BONENAVI, a computer-aided diagnostic system, is used in bone scintigraphy. This system provides the artificial neural network (ANN) and bone scan index (BSI) values. ANN is associated with the possibility of bone metastasis, while BSI is related to the amount of bone metastasis. The degree of uptake on bone scintigraphy can be affected by the type of bone metastasis. Therefore, the ...

Prostate cancer is the most common cancer in men in Western countries, with a high incidence of bone metastasis. The bony metastasis is incurable and contributes significantly to disease-specific morbidity and mortality. The molecular and cellular mechanisms leading to the development of bone metastasis in prostate cancer remain unclear, but are currently under intensive investigation. In this ...

Prostate cancer metastasis to the bone occurs at high frequency in patients with advanced disease, causing significant morbidity and mortality. Over a century ago, the "seed and soil" theory was proposed to explain organ-specific patterns of metastases. Today, this theory continues to be relevant as we continue to discover factors involved in the attraction and subsequent growth of prostate can...

Breast cancer is the most prevalent cancer among females worldwide leading to approximately 350,000 deaths each year. It has long been known that cancers preferentially metastasize to particular organs, and bone metastases occur in ~70% of patients with advanced breast cancer. Breast cancer bone metastases are predominantly osteolytic and accompanied by increased fracture risk, pain, nerve comp...
