Abstract

BACKGROUND: Formation of tumour mass is one symptom of osteosarcoma development. Caffeic acid has been known to provide effective treatment but has less side effect for some cancer therapy. Studies reported that caffeic acid might promote apoptosis in MG-63 osteosarcoma cells, however, the effect of caffeic acid treatment in preventing tumour mass formation has not been well elucidated, especially in MG-63 cells-induced nude mice in vivo.METHODS: MG-63 cells were pre-treated with 0, 1, or 10 µg/mL caffeic acid, and 6 hours after pre-treatment, MG-63 cells were injected into subcutaneous space of mice to induce osteosarcoma. Another model was also created by subcutaneously injecting MG-63 cells to the back of mice, and after 48 days, the visible tumour mass was injected intra-tumour with 0 or 10 µg/mL caffeic acid every 7 days for 6 times. After 90 days, mice were anaesthetised, and the nodule pictures were taken for observation and measurement. RESULTS: In pre-treated MG-63 cells-induced mice, volumes of the mass decreased in reverse with the dose of caffeic acid given. Ten µg/mL caffeic acid pre-treatment was able to significantly lower the mass volume compared to the untreated (p<0.05). Meanwhile, the intra-tumour treatment of 10 µg/mL caffeic acid, even though not significant, was able to inhibit tumour mass formation.CONCLUSION: Results of caffeic acid pre-treatment and caffeic acid treatment in tumour mass of mice show that caffeic acid is able to inhibit the MG-63 cells formation. This suggests that caffeic acid can be a potential anti-cancer agent.KEYWORDS: caffeic acid, osteosarcoma, MG-63 cells, tumour mass

Abstract

BACKGROUND: Metastases are simply known as cancers spread to another part of the body, and often be responsible for the severity of cancer prognosis. Somehow, the complex mechanisms of metastases are not fully understood yet.CONTENT: The characteristic of cancer is akin to a never-healing wound. Cancer cells are plastic and dynamic as they build their niches and developed into metastases, even when they seem dormant. Therefore, cancer cells can survive the immune system. Recent research has shown the distinct biology of metastasis-initiating cell, which leads to tumor development in distant organs, immune surveillance evasion, and co-option of metastatic micro-environments. Effective cancer therapies must consider the regenerative states of metastatic malignancies and have careful observation of patient phenotypes.SUMMARY: This review aimed to provide an insight on genesis and characteristics of metastases, starting from its seeding and dormancy, until the advance phase. Thus, developing therapy for cancer metastases should not start as it grows, but even as earlier strategies since the primary tumor was detected.KEYWORDS: cancer metastasis, DTC, CTC, CSC, dormancy, pre-metastatic niche, plasticity

Abstract

BACKGROUND: Increase in inflammatory cytokine levels promotes pathological osteoclast differentiation. Caffeic acid has anti-inflammatory properties and can inhibit osteoclast bone resorption. In vitro studies have reported the ability of caffeic acid in inhibiting osteoclastogenesis pathways, however the in vivo study is rarely conducted. The aim of this study is to examine the role of caffeic acid in reducing inflammation and inhibiting osteoclastogenesis in Adjuvant-Induced Arthritis (AIA) rats.METHODS: Rats were injected with Freund’s Complete Adjuvant (CFA) and mineral oil. One day after injection, various concentration (0, 5, 25, 125 mg) of caffeic acid were given gastro-intestinally. Swelling degree in rats’ ankle joints was determined by measuring height and width of each ankle joint. Bone loss level was examined with soft X-ray, and then bone density was calculated. To examine osteoclastogenesis, ankle joints were stained with Tartrate-Resistant Acid Phosphatase (TRAP) and evaluated microscopically. RESULTS: Ankle joints of AIA rats had severe swelling before treated, yet the swelling was reduced based on concentration-dependent after receiving caffeic acid. Severe bone loss in AIA rats’ ankle joints were also observed, however the treatment of 125 mg caffeic acid showed remarkable inhibition effect toward rats’ bone loss. Osteoclastogenesis in AIA rats’ ankle joints were higher than the normal ones, as indicated with high TRAP-positive Multinucleated Cells (MNCs). But low number of TRAP-positive MNCs was observed in ankle joint of AIA rats that received 125 mg caffeic acid.CONCLUSION: Administration of caffeic acid can reduce the degree of swallowing, inhibit bone loss, and inhibit osteoclastogenesis in ankle joint of arthritis-induced rats.KEYWORDS: caffeic acid, osteoclastogenesis, bone loss, swelling, inflammation, RANKL, TNF-α
