Propranolol: A "Pick and Roll" Team Player in Benign Tumors and Cancer Therapies.

Research on cancer therapies focuses on processes such as angiogenesis, cell signaling, stemness, metastasis, and drug resistance and inflammation, all of which are influenced by the cellular and molecular microenvironment of the tumor. Different strategies, such as antibodies, small chemicals, hormones, cytokines, and, recently, gene editing techniques, have been tested to reduce the malignancy and generate a harmful microenvironment for the tumor. Few therapeutic agents have shown benefits when administered alone, but a few more have demonstrated clear improvement when administered in combin

Roles of circadian clocks in cancer pathogenesis and treatment.

Circadian clocks are ubiquitous timing mechanisms that generate approximately 24-h rhythms in cellular and bodily functions across nearly all living species. These internal clock systems enable living organisms to anticipate and respond to daily changes in their environment in a timely manner, optimizing temporal physiology and behaviors. Dysregulation of circadian rhythms by genetic and environmental risk factors increases susceptibility to multiple diseases, particularly cancers. A growing number of studies have revealed dynamic crosstalk between circadian clocks and cancer pathways, providi

Sexual dimorphism in cancer: molecular mechanisms and precision oncology perspectives.

Sex differences play a crucial role in determining tumor incidence, treatment sensitivity, and prognosis among men and women. However, current clinical cancer treatment strategies fail to account for these differences. Furthermore, the underlying mechanisms of tumor disparities between sexes remain elusive. Sex differences in sex chromosomes, hormone levels, metabolism, and immunity synergistically contribute to tumor-related disparities. As the demand for precision medicine escalates, there is an urgent need to conduct further exploration and research to address the tumor differences between

IL-20RB mediates tumoral response to osteoclastic niches and promotes bone metastasis of lung cancer.

Bone is a common site of metastasis in lung cancer, but the regulatory mechanism remains incompletely understood. Osteoclasts are known to play crucial roles in osteolytic bone metastasis by digesting bone matrix and indirectly enhancing tumor colonization. In this study, we found that IL receptor 20 subunit β (IL-20RB) mediated a direct tumoral response to osteoclasts. Tumoral expression of IL-20RB was associated with bone metastasis of lung cancer, and functionally, IL-20RB promoted metastatic growth of lung cancer cells in bone. Mechanistically, tumor cells induced osteoclasts to secrete th

Where Do Bone-Targeted Agents RANK in Breast Cancer Treatment?

Breast cancer cells preferentially metastasise to the skeleton, owing, in part, to the fertile environment provided by bone. Increased bone turnover releases growth factors that promote tumour cell growth. In turn, tumour cells release factors that stimulate further bone turnover, resulting in a vicious cycle of metastasis growth and bone destruction. The RANK-RANK ligand (RANKL) pathway plays a key role in this cycle, and inhibition of RANKL using the fully-human monoclonal antibody denosumab, has demonstrated efficacy in delaying skeletal complications associated with bone metastases in thre

Malignant Pleural Effusion: Palliative Managements and Indication for Pleurodesis Based on Survival Scores.

Neoplastic pleural effusion is one in which malignant neoplastic cells are detected in the pleural fluid or in the parietal pleura. When secondary, it confirms disseminated neoplastic disease and suggests a reduced life expectancy and low quality of life. This review was described by a group of physician members of the Brazilian Society of Oncological Surgery regarding the treatment of neoplastic pleural effusion, developed to guide surgeons, palliative care physicians and clinical oncologists in their clinical practice to assess patients indicated for pleurodesis based on survival scores.

Tumour-associated macrophages: versatile players in the tumour microenvironment.

Tumour-Associated Macrophages (TAMs) are one of the pivotal components of the tumour microenvironment. Their roles in the cancer immunity are complicated, both pro-tumour and anti-cancer activities are reported, including not only angiogenesis, extracellular matrix remodeling, immunosuppression, drug resistance but also phagocytosis and tumour regression. Interestingly, TAMs are highly dynamic and versatile in solid tumours. They show anti-cancer or pro-tumour activities, and interplay between the tumour microenvironment and cancer stem cells and under specific conditions. In addition to the c

Trial watch: beta-blockers in cancer therapy.

Compelling evidence supports the hypothesis that stress negatively impacts cancer development and prognosis. Irrespective of its physical, biological or psychological source, stress triggers a physiological response that is mediated by the hypothalamic-pituitary-adrenal axis and the sympathetic adrenal medullary axis. The resulting release of glucocorticoids and catecholamines into the systemic circulation leads to neuroendocrine and metabolic adaptations that can affect immune homeostasis and immunosurveillance, thus impairing the detection and eradication of malignant cells. Moreover, catech

Innovative Biomaterials for the Treatment of Bone Cancer.

Bone cancer is a demanding challenge for contemporary medicine due to its high frequency of presentation and significant heterogeneity of malignant lesions developing within the bone. To date, available treatments are rarely curative and are primarily aimed at prolonging patients' survival and ameliorating their quality of life. Furthermore, both pharmacological and surgical therapies are aggravated by a consistent burden of adverse events and subsequent disability due to the loss of healthy bone structural and functional properties. Therefore, great research efforts are being made to develop
