Ammonium metabolism rewiring in the prostate cancer microenvironment: Mechanisms and clinical prospects.

Ammonium metabolism represents a critically understudied yet pivotal driver of prostate tumorigenesis and tumor microenvironment (TME) remodeling. The interplay between tumor metabolic reprogramming and the tumor microenvironment has emerged as a critical frontier in oncology research. While previous studies on prostate cancer metabolism have predominantly focused on lipid metabolism and the Warburg effect, the role of ammonium metabolism, particularly the urea cycle in tumor immune regulation remains insufficiently explored. This metabolic reprogramming constitutes a central node connecting c

What is the relationship between bone turnover markers and skeletal-related events in patients with bone metastases from solid tumors and in patients with multiple myeloma? A systematic review and meta-regression analysis.

INTRODUCTION: As a result of the negative impact of bone metastases on patient quality of life, it is important to identify patients at increased risk of skeletal-related events (SREs). Biochemical markers produced by osteoblasts and osteoclasts may provide an early indicator of treatment response to antiresorptive therapy. We aimed to explore the relationship between change in the urinary bone turnover marker cross-linked N-terminal telopeptide of type 1 collagen (uNTX) at the earliest time of steady state and risk of SREs. METHODS: A comprehensive search of eight bibliographic databases and

Immunotherapy is preferred to other cancer therapies, offering precise targeting of malignant cells while simultaneously strengthening the immune system's complex responses. Advances in this novel field of science have been closely linked to a deeper knowledge of tumor biology, particularly the intricate interplay between tumor cells, the immune system, and the tumor microenvir

The dual balance of the cytokine network: key messengers of immune activation and triggers of cytokine storm.

The cytokine network is the central regulatory system for intercellular communication within the immune system. Its proper function depends on the dynamic balance between pro-inflammatory and anti-inflammatory cytokines. Through complex positive and negative feedback loops, this balance precisely regulates the intensity and duration of immune responses, thereby playing a critical role in both physiological and pathological states. This review systematically summarizes the compositional features and classification framework of the cytokine network, as well as the mechanisms by which it maintain

Роль ядерных рецепторов в развитии множественного склероза: обзор.

Множественный склероз (MS) является следствием раннего возбудительного демиэлирования и прогрессивных нейродегенеративных повреждений в центральной нервной системе (КНС). Несмотря на неясный патогенез MS, происходят два основных процесса: ремонт олигодендроцита и липидный метаболизм. Было отмечено, что ядерные рецепторы играют роль линейных датчиков, регуляторов транскрипционных факторов и модуляторов генного выражения. Один из членов этой семьи, ретиноид X-рецептор (RXR), который образует гетеродимерный комплекс с рецептором печени X (LXR), был замешан в патофизиологии MS. Кроме того, было вы

Marketed nonsteroidal anti-inflammatory agents, antihypertensives, and human immunodeficiency virus protease inhibitors: as-yet-unused weapons of the oncologists' arsenal.

Experimental data indicate that several pharmacological agents that have long been used for the management of various diseases unrelated to cancer exhibit profound in vitro and in vivo anticancer activity. This is of major clinical importance, since it would possibly aid in reassessing the therapeutic use of currently used agents for which clinicians already have experience. Further, this would obviate the time-consuming process required for the development and the approval of novel antineoplastic drugs. Herein, both pre-clinical and clinical data concerning the antineoplastic function of dist

The potential therapeutic role of extracellular vesicles in critical-size bone defects: Spring of cell-free regenerative medicine is coming.

In recent years, the incidence of critical-size bone defects has significantly increased. Critical-size bone defects seriously affect patients' motor functions and quality of life and increase the need for additional clinical treatments. Bone tissue engineering (BTE) has made great progress in repairing critical-size bone defects. As one of the main components of bone tissue engineering, stem cell-based therapy is considered a potential effective strategy to regenerate bone tissues. However, there are some disadvantages including phenotypic changes, immune rejection, potential tumorigenicity,

Current progress and mechanisms of bone metastasis in lung cancer: a narrative review.

Lung cancer is a kind of malignant tumor with rapid progression and poor prognosis. Distant metastasis has been the main cause of mortality among lung cancer patients. Bone is one of the most common sites. Among all lung cancer patients with bone metastasis, most of them are osteolytic metastasis. Some serious clinical consequences like bone pain, pathological fractures, spinal instability, spinal cord compression and hypercalcemia occur as well. Since the severity of bone metastasis in lung cancer, it is undoubtedly necessary to know how lung cancer spread to bone, how can we diagnose it and

The aim of this review is to present the potential application of camphor-a bicyclic monoterpene ketone-in the prevention of skin infections. Skin diseases represent a heterogeneous group of disorders characterized by prolonged symptoms that significantly diminish the quality of life. They affect the dermis, the epidermis, and even subcutaneous tissue. They very often have a bacterial or fungal background. Therapy for dermatological skin disorders is difficult and long-term. Therefore, it is important to find a compound, preferably of natural origin, that (i) prevents the initiation of this in

TGF-β in hematologic malignancies: molecular functions and clinical applications.

Transforming growth factor-β (TGF-β) represents a family of multifunctional cytokines, primarily secreted by megakaryocytes, monocytes, T lymphocytes, bone marrow stromal cells, and other cell types. TGF-β plays an essential role in various physiological processes, including the regulation of cell proliferation, differentiation, apoptosis, and immune homeostasis. As a key immunoregulatory cytokine, TGF-β contributes to an immunosuppressive network within the microenvironment of hematologic malignancies by modulating the functions of both adaptive and innate immune cells. Current studies have s

Observational study of the bisphosphonate-related osteonecrosis of jaws.

INTRODUCTION: The bisphosphonate-related osteonecrosis of the jaw was first referred to in 2003. Bisphosphonates action is focused on the osteoclasts. The drastic inhibition of the osteoclastic function is harmful for the jaws which are the only bones of the human skeleton in relative contact with the external environment. The adverse effects of the bisphosphonate-related therapy include the pathology for which they are prescribed, the atypical fractures in pathological bone. METHOD: The aim of this research was to analyze the risk factors and the treatment methods in case of osteonecrosis of

Current options for the treatment of Paget's disease of the bone.

Paget's disease of bone (PDB) is a chronic bone remodelling disorder characterized by increased osteoclast-mediated bone resorption, with subsequent compensatory increases in new bone formation, resulting in a disorganized mosaic of woven and lamellar bone at affected skeletal sites. This disease is most often asymptomatic but can be associated with bone pain or deformity, fractures, secondary arthritis, neurological complications, deafness, contributing to substantial morbidity and reduced quality of life. Neoplastic degeneration of pagetic bone is a relatively rare event, occurring with an i

Unlocking the potential of tumor-targeting peptides in precision oncology.

Targeted cancer therapy has emerged as a promising alternative to conventional chemotherapy, which is often plagued by poor selectivity, off-target effects, and drug resistance. Among the various targeting agents in development, peptides stand out for their unique advantages, including minimal immunogenicity, high tissue penetration, and ease of modification. Their small size, specificity, and flexibility allow them to target cancer cells while minimizing damage to healthy tissue selectively. Peptide-based therapies have shown great potential in enhancing the efficacy of drug delivery, improvi

Tumor heterogeneity as a driver of drug resistance and its implications for personalized therapy.

Tumors are highly dynamic diseases characterized by significant heterogeneity. They consist of multiple cellular populations with distinct properties that respond differently to therapeutic pressure. This heterogeneity may arise from spatial variation across tumor regions (spatial heterogeneity) as well as from temporal changes during tumor evolution and treatment (temporal heterogeneity). As a consequence, drug-resistant subclones often emerge under therapy and contribute to treatment failure. Advances in single-cell and spatial multi-omics technologies enable precise quantification of tumor

A case of paraprotein-negative POEMS syndrome: Case report and literature review.

RATIONALE: POEMS syndrome is a rare monoclonal plasma cell disease. The diagnosis of POEMS requires polyradiculoneuropathy and monoclonal plasma proliferating as 2 mandatory criteria, at least 1 of the major criteria (Castleman disease, elevated vascular endothelial growth factor level, and sclerotic bone lesion), and at least 1 of the minor criteria (organomegaly, extravascular volume overload, endocrinopathy, skin changes, papilledema, and thrombocytosis/polycythemia). This multisystem disorder is of high heterogeneity, and few variants of POEMS with no evidence of monoclonal gammopathy have
