“…In line with previous results, IL-1β, IL-10 and CCL5 were involved in multiple signaling pathways that affect the development and progression of tumors. IL-1β caused expansion of the bone metastatic niche and led to tumor proliferation in breast cancer (45). IL-10 and integrin pathways have been reported to be strongly associated with head and neck cancer progression (46).…”

“…Additionally, it was observed that in tumour-naïve mice, a single dose of IL-1β dual selective antagonist reduces osteoclast and osteoblast activity and IL-1β expression, also following continuous administration of IL-1β dual selective antagonist for more than 21 days [45]. Similarly, Tulotta et al [46] using patient samples with stage II/III breast cancer, humanized mouse models of spontaneous breast cancer bone metastasis, genetic manipulation of breast cancer cells (MDA-MB-231-IL-1B+, T47D-IL-1B+ and MCF7-IL-1B+) and in vitro models (co-culture between HS5 or OB1 cells and MDA-MB-231 or T47D cells) demonstrated that not only the IL-1R antagonist, anakinra, but also the anti that a IL-1β antibody, canakinumab, inhibited breast tumor growth and progression to bone metastasis. Additionally, the production of IL-1β by tumor cells promoted epithelial-mesenchymal transition, invasion, migration, and bone colonization.…”

“…Additionally, the production of IL-1β by tumor cells promoted epithelial-mesenchymal transition, invasion, migration, and bone colonization. Contact between tumor and osteoblasts or bone marrow cells increased IL-1β secretion from all three cell types [46].…”

“…In a humanized model of spontaneous breast cancer metastasis to bone, production of IL-1β by cancer cells promotes EMT (altered E-Cadherin, N-Cadherin, and G-Catenin), invasion, migration, and bone colonization. Inhibitor of IL-1β, Anakinra or Canakinumab, reduces metastasis and the number of cancer cells shed into the circulation ( 72 ). Clinical data show that continuous inhibition of IL-1 activity inhibits breast cancer growth and bone metastasis ( 73 ).…”

“…However, metastatic cancer cell proliferation does not occur immediately with a specific temporal pattern because cancer cells seeding at distant bones may remain quiescent until stimulus signals from the bone marrow microenvironment drive cancer cells proliferation into overt metastases in the bone ( 27 ). It is found that activated osteoclasts and increased osteoclastic bone resorption accelerate the growth of DTCs into overt metastases ( 72 ). In addition, it is hypothesized that when metastatic tumor cells arrive in the bone, they may be stimulated to form overt metastasis through an expansion of the tumor associated vasculature ( 72 ).…”
