Gut microbiota and microbial metabolites for osteoporosis.

Osteoporosis is an age-related bone metabolic disease. As an essential endocrine organ, the skeletal system is intricately connected with extraosseous organs. The crosstalk between bones and other organs supports this view. In recent years, the link between the gut microecology and bone metabolism has become an important research topic, both in preclinical studies and in clinical trials. Many studies have shown that skeletal changes are accompanied by changes in the composition and structure of the gut microbiota (GM). At the same time, natural or artificial interventions targeting the GM can

Synergistic Enhancement of Cancer Therapy Using HDAC Inhibitors: Opportunity for Clinical Trials.

Chemotherapy is one of the most established and effective treatments for almost all types of cancer. However, the elevated toxicity due to the non-tumor-associated effects, development of secondary malignancies, infertility, radiation-induced fibrosis and resistance to treatment limit the effectiveness and safety of treatment. In addition, these multiple factors significantly impact quality of life. Over the last decades, our increased understanding of cancer epigenetics has led to new therapeutic approaches and the promise of improved patient outcomes. Epigenetic alterations are commonly foun

Epigenetic Activation of CCDC183-AS1 Promotes Osteoclastogenesis and Prostate Cancer Bone Metastasis Through the FUBP1/LIGHT Axis.

Bone metastasis (BM) is a major contributor to poor prognosis of prostate cancer (PCa); however, the underlying mechanisms of PCa BM remain poorly understood. A better understanding of these processes may provide critical insights for developing effective preventive and therapeutic strategies for PCa BM. In this study, significant upregulation of CCDC183-AS1 in PCa BM is identified, which is associated with disease progression. CCDC183-AS1 overexpression enhanced the ability of PCa cells to spread to the bone by inducing osteoclastogenesis and aiding in the creation of a BM niche. Mechanistica

Extracellular Vesicle-Associated miRNAs and Chemoresistance: A Systematic Review.

Cancer is a leading public health issue globally, and diagnosis is often associated with poor outcomes and reduced patient survival. One of the major contributors to the fatality resultant of cancer is the development of resistance to chemotherapy, known as chemoresistance. Furthermore, there are limitations in our ability to identify patients that will respond to therapy, versus patients that will develop relapse, and display limited or no response to treatment. This often leads to patients being subjected to multiple futile treatment cycles, and results in a reduction in their quality of lif

Targeting strategies for bone diseases: signaling pathways and clinical studies.

Since the proposal of Paul Ehrlich's magic bullet concept over 100 years ago, tremendous advances have occurred in targeted therapy. From the initial selective antibody, antitoxin to targeted drug delivery that emerged in the past decades, more precise therapeutic efficacy is realized in specific pathological sites of clinical diseases. As a highly pyknotic mineralized tissue with lessened blood flow, bone is characterized by a complex remodeling and homeostatic regulation mechanism, which makes drug therapy for skeletal diseases more challenging than other tissues. Bone-targeted therapy has b

Enhancing the Bioavailability of Resveratrol: Combine It, Derivatize It, or Encapsulate It?

Overcoming the limited bioavailability and extensive metabolism of effective in vitro drugs remains a challenge that limits the translation of promising drugs into clinical trials. Resveratrol, despite its well-reported therapeutic benefits, is not metabolically stable and thus has not been utilized as an effective clinical drug. This is because it needs to be consumed in large amounts to overcome the burdens of bioavailability and conversion into less effective metabolites. Herein, we summarize the more relevant approaches to modify resveratrol, aiming to increase its biological and therapeut

USP33 Promotes Lung Adenocarcinoma Brain Metastasis by Inhibiting the K48-Linked Ubiquitination and Degradation of S100A9 and Facilitating Vimentin Secretion.

Brain metastasis has a deterministic influence on the evolutionary trajectory of lung adenocarcinoma (LUAD). Given the profound clinical importance of LUAD brain metastases and the formidable obstacles that hinder their precise prediction, novel therapeutic targets are urgently needed. Notably, a substantial fraction of lung carcinoma cells in brain metastatic foci demonstrates marked S100A9 overexpression. However, whether these cells represent the primary drivers of brain metastasis requires further elucidation. Coculture of S100A9-overexpressing LUAD cells with human brain microvascular end

Reprogramming of nitrogen metabolism in tumors: mechanisms and therapeutic implications.

Nitrogen metabolism plays a key role in maintaining normal physiological functions of the organism and cell proliferation and differentiation. Nitrogen metabolism in normal human body maintains a dynamic balance to meet the body's demand for synthesis of biological macromolecules such as proteins and nucleic acids. However, in the process of tumor development, the nitrogen metabolism of tumor cells is reprogrammed to meet the demand of rapid proliferation, showing significantly different metabolic characteristics from normal cells. Key enzymes in the tumor microenvironment affect nitrogen meta

Ref-1/APE1 is activated in a variety of cancers, including prostate, colon, pancreatic, ovarian, lung an

Bone targeted nano-drug and nano-delivery.

There are currently no targeted delivery systems to satisfactorily treat bone-related disorders. Many clinical drugs consisting of small organic molecules have a short circulation half-life and do not effectively reach the diseased tissue site. This coupled with repeatedly high dose usage that leads to severe side effects. With the advance in nanotechnology, drugs contained within a nano-delivery device or drugs aggregated into nanoparticles (nano-drugs) have shown promises in targeted drug delivery. The ability to design nanoparticles to target bone has attracted many researchers to develop n
