Targeting Intercellular Communication in the Bone Microenvironment to Prevent Disseminated Tumor Cell Escape from Dormancy and Bone Metastatic Tumor Growth.

Metastasis to the bone is a common feature of many cancers including those of the breast, prostate, lung, thyroid and kidney. Once tumors metastasize to the bone, they are essentially incurable. Bone metastasis is a complex process involving not only intravasation of tumor cells from the primary tumor into circulation, but extravasation from circulation into the bone where they meet an environment that is generally suppressive of their growth. The bone microenvironment can inhibit the growth of disseminated tumor cells (DTC) by inducing dormancy of the DTC directly and later on following forma

Advancing Cancer-Targeted Nanotherapies with Tumor Homing Peptides.

The development of smart nanoparticles for precision medicine in anticancer drug delivery and controlled release has the potential to revolutionize cancer treatment. This progress is driven by expanding body of preclinical and early clinical studies on anticancer nanoparticles. Despite these advancements, a critical challenge remains achieving a selective and efficient tumor accumulation, along with effective extravasation and deep tissue penetration of nanoparticles into the tumor parenchyma. Affinity targeting strategies using ligands such as homing peptides and antibodies leverage molecular

The ambiguous role of obesity in oncology by promoting cancer but boosting antitumor immunotherapy.

Obesity is nowadays considered a pandemic which prevalence's has been steadily increasingly in western countries. It is a dynamic, complex, and multifactorial disease which propitiates the development of several metabolic and cardiovascular diseases, as well as cancer. Excessive adipose tissue has been causally related to cancer progression and is a preventable risk factor for overall and cancer-specific survival, associated with poor prognosis in cancer patients. The onset of obesity features a state of chronic low-grade inflammation and secretion of a diversity of adipocyte-derived molecules

The burden and predictors of venous thromboembolic diseases in patients with multiple primary malignancies.

BackgroundVenous thromboembolism (VTE) represents a considerable burden on cancer patients' survival and quality of life, but this burden varies based on the patient's baseline characteristics and cancer-related factors. Although solid evidence on the predictors and effect of VTE in cancer patients exists.AimTo evaluate VTE rate, morbidity, and mortality to develop parameters that could predict VTEs and their associated mortality in patients with multiple primary malignancies (MPMs).Method and resultsThis was a retrospective cohort study that took place at King Abdulaziz Medical City, Riyadh,

Should oncologists trust cannabinoids?

Cannabis enjoyed a "golden age" as a medicinal product in the late 19th, early 20th century, but the increased risk of overdose and abuse led to its criminalization. However, the 21st century have witnessed a resurgence of interest and a large body of literature regarding the benefits of cannabinoids have emerged. As legalization and decriminalization have spread around the world, cancer patients are increasingly interested in the potential utility of cannabinoids. Although eager to discuss cannabis use with their oncologist, patients often find them to be reluctant, mainly because clinicians

Recent Advances in the Development and Utilization of Nanoparticles for the Management of Malignant Solid Tumors.

The purpose of nanotechnology-based drug delivery systems or novel drug delivery systems is to improve the effectiveness of therapy, and their promising properties have led to their increasing significance in the management of cancer. The researchers have primarily focused on designing novel nanocarriers, like nanoparticles (NPs), that can effectively deliver drugs to target cells and respond specifically to conditions particular to cancer. Whether passive or active targeting, these nanocarriers can deliver therapeutic cargoes to the tumor site to release the drug from the drug delivery system

Биологическая роль мономеров традиционной китайской медицины в нейронных расстройствах.

Традиционная китайская медицина (TCM) является биоактивным соединением, извлекаемым из китайских травяных лекарственных препаратов, обладающих определенной биологической активностью и фармакологическими последствиями, и привлекла большое внимание к лечению нейронных заболеваний. Однако применение мономеров ТХМ ограничено их низкой растворимостью и низкой способностью пересекать барьер кровеносного мозга (ББД). Экзосомы представляют собой небольшие внеклеточные везикли (ЭМ) диаметром от 30 до 150 нм и могут использоваться в качестве носителей наркотиков, которые непосредственно предназначены дл

Androgen Receptor-CaMKK2 Axis in Prostate Cancer and Bone Microenvironment.

The skeletal system is of paramount importance in advanced stage prostate cancer (PCa) as it is the preferred site of metastasis. Complex mechanisms are employed sequentially by PCa cells to home to and colonize the bone. Bone-resident PCa cells then recruit osteoblasts (OBs), osteoclasts (OCs), and macrophages within the niche into entities that promote cancer cell growth and survival. Since PCa is heavily reliant on androgens for growth and survival, androgen-deprivation therapy (ADT) is the standard of care for advanced disease. Although it significantly improves survival rates, ADT detrime

Oxidized Lipids in Persistent Pain States.

Chemotherapy, nerve injuries, or diseases like multiple sclerosis can cause pathophysiological processes of persistent and neuropathic pain. Thereby, the activation threshold of ion channels is reduced in peripheral sensory neurons to normally noxious stimuli like heat, cold, acid, or mechanical due to sensitization processes. This leads to enhanced neuronal activity, which can result in mechanical allodynia, cold allodynia, thermal hyperalgesia, spontaneous pain, and may initiate persistent and neuropathic pain. The treatment options for persistent and neuropathic pain patients are limited; f

Current Advances of Nanomedicines Delivering Arsenic Trioxide for Enhanced Tumor Therapy.

Arsenic trioxide (ATO) is one of the first-line chemotherapeutic drugs for acute promyelocytic leukemia. Its anti-cancer activities against various human neoplastic diseases have been extensively studied. However, the clinical use of ATO for solid tumors is limited, and these limitations are because of severe systemic toxicity, low bioavailability, and quick renal elimination before it reaches the target site. Although without much success, several efforts have been made to boost ATO bioavailability toward solid tumors without raising its dose. It has been found that nanomedicines have various

Potential Associations between Vascular Biology and Hodgkin's Lymphoma: An Overview.

Hodgkin's lymphoma (HL) is a lymphatic neoplasm typically found in the cervical lymph nodes. The disease is multifactorial, and in recent years, the relationships between various vascular molecules have been explored in the field of vascular biology. The connection between vascular biology and HL is intricate and the roles of several pathways remain unclear. This review summarizes the cellular and molecular relationships between vascular biology and HL. Proteins associated with various functions in vascular biology, including cytokines (TNF-α, IL-1, IL-13, and IL-21), chemokines (CXCL10, CXCL1

Cardiogenic shock among cancer patients.

Sophisticated cancer treatments, cardiovascular risk factors, and aging trigger acute cardiovascular diseases in an increasing number of cancer patients. Among acute cardiovascular diseases, cancer treatment, as well as the cancer disease itself, may induce a cardiogenic shock. Although increasing, these cardiogenic shocks are still relatively limited, and their management is a matter of debate in cancer patients. Etiologies that cause cardiogenic shock are slightly different from those of non-cancer patients, and management has some specific features always requiring a multidisciplinary appro
