Osteoporosis and the Potential of Cell-Based Therapeutic Strategies.

Osteoporosis, the most common chronic metabolic bone disease, is characterized by low bone mass and increased bone fragility. Nowadays more than 200 million individuals are suffering from osteoporosis and still the number of affected people is dramatically increasing due to an aging population and longer life, representing a major public health problem. Current osteoporosis treatments are mainly designed to decrease bone resorption, presenting serious adverse effects that limit their safety for long-term use. Numerous studies with mesenchymal stem cells (MSCs) have helped to increase the knowl

Targeting cancer stem cells with CAR-based immunotherapy: biology, evidence, and future directions.

Cancer stem cells (CSCs) are pivotal in tumor initiation, progression, and relapse, underscoring the need for targeted therapies to achieve lasting responses. This review delves into CSC biology, highlighting their tumor-initiating potential demonstrated through limiting dilution assays and their role in resistance to therapies. Although successful CAR therapies, such as anti-CD19 CAR T-cells, can induce complete responses without directly targeting CSCs, CAR strategies focusing on CSCs may offer promising avenues to prevent recurrence. We assess CAR therapies targeting CSC-specific antigens,

Metastatic Spread in Prostate Cancer Patients Influencing Radiotherapy Response.

Radiotherapy and surgery are curative treatment options for localized prostate cancer (PCa) with a 5-year survival rate of nearly 100%. Once PCa cells spread into distant organs, such as bone, the overall survival rate of patients drops dramatically. The metastatic cascade and organotropism of PCa cells are regulated by different cellular subtypes, organ microenvironment, and their interactions. This cross-talk leads to pre-metastatic niche formation that releases chemo-attractive factors enforcing the formation of distant metastasis. Biological characteristics of PCa metastasis impacting on m

The Anti-Cancer Effect of Cinnamon Aqueous Extract: A Focus on Hematological Malignancies.

Cinnamon is an evergreen and tropical plant of the family Lauraceae, growing particularly in Sri Lanka, whose aqueous extract has been tested in different studies to evaluate its possible use as an anti-cancer compound. Both in vitro and in vivo experiments seem to confirm that it acts on various cellular pathways, contributing to down-regulating the activity of molecules that stimulate the proliferation and survival of cells such as the transcription factors NF-KB and AP-1, COX-2, dihydrofolate reductase and pro-angiogenic substances such as VEGF, while up-regulating the function of immune ce

Lung cancer immunotherapy: progress, pitfalls, and promises.

Lung cancer is the primary cause of mortality in the United States and around the globe. Therapeutic options for lung cancer treatment include surgery, radiation therapy, chemotherapy, and targeted drug therapy. Medical management is often associated with the development of treatment resistance leading to relapse. Immunotherapy is profoundly altering the approach to cancer treatment owing to its tolerable safety profile, sustained therapeutic response due to immunological memory generation, and effectiveness across a broad patient population.

Role of myeloid-derived suppressor cells in tumor recurrence.

The establishment of primary tumor cells in distant organs, termed metastasis, is the principal cause of cancer mortality and is a crucial therapeutic target in oncology. Thus, it is critical to establish a better understanding of metastatic progression for the future development of improved therapeutic approaches. Indeed, such development requires insight into the timing of tumor cell dissemination and seeding of distant organs resulting in occult lesions. Following dissemination of tumor cells from the primary tumor, they can reside in niches in distant organs for years or decades, following

Diagnostic evaluation of chronic pruritus may require a meticulous app

Mechanisms, Diagnosis and Treatment of Bone Metastases.

Bone and bone marrow are among the most frequent metastatic sites of cancer. The occurrence of bone metastasis is frequently associated with a dismal disease outcome. The prevention and therapy of bone metastases is a priority in the treatment of cancer patients. However, current therapeutic options for patients with bone metastatic disease are limited in efficacy and associated with increased morbidity. Therefore, most current therapies are mainly palliative in nature. A better understanding of the underlying molecular pathways of the bone metastatic process is warranted to develop novel, wel

The Evolving Landscape of Immune Regulation and Immunotherapy in Cholangiocarcinoma and Biliary Tract Cancer.

Cholangiocarcinoma (CCA) is an aggressive and molecularly heterogeneous malignancy characterized by a profoundly immunosuppressive tumor microenvironment (TME) and historically limited therapeutic options. Recent advances have redefined the treatment paradigm, with phase III trials establishing chemoimmunotherapy as a standard of care and multi-omic profiling elucidating the interplay between tumor genomics, stromal architecture, and immune regulation. Despite these gains, durable clinical benefit remains confined to a minority of patients, reflecting convergent mechanisms of primary and acqui

Emerging insights into the immunosuppressive tumor microenvironment and its implications for glioblastoma immunotherapy.

Glioblastoma is considered the most common and lethal form of brain cancer. Despite tremendous progress in glioblastoma therapeutics, the profound intra- and inter-tumoral heterogeneity of glioblastoma tumors, the difficulty of agents to cross the blood-brain barrier (BBB), the development of drug resistance as well as the immunosuppressive tumor microenvironment (TME) predominantly account for the failure of existing conventional and targeted therapies. Therefore, there is a growing necessity to decipher the complexity of the TME that promotes immunosuppression and to discover innovative stra

This paper systematically reviews the current status and future trends of ACT, covering lymphokine-activated killer cells (LAK), tumor-infiltrating lymphocytes (TIL), cytokine-induced killer cells (CIK), dendritic cells (DC), T cell receptor-modified T cells (TCR-T), chimeric antigen receptor T cells (CAR-T), natural killer (NK) cells, chimeric antigen receptor-modified NK cells (CAR-NK), and the emerging CAR-M. The paper focuses on emerging technological approaches, including

EP300 as a Molecular Integrator of Fibrotic Transcriptional Programs.

Fibrosis is a condition characterized by the excessive accumulation of extracellular matrix proteins in tissues, leading to organ dysfunction and failure. Recent studies have identified EP300, a histone acetyltransferase, as a crucial regulator of the epigenetic changes that contribute to fibrosis. In fact, EP300-mediated acetylation of histones alters global chromatin structure and gene expression, promoting the development and progression of fibrosis. Here, we review the role of EP300-mediated epigenetic regulation in multi-organ fibrosis and its potential as a therapeutic target. We discuss

Ligand-based CAR-T cell: Different strategies to drive T cells in future new treatments.

Chimeric antigen receptor (CAR)-based therapies are presented as innovative treatments for multiple malignancies. Despite their clinical success, there is scientific evidence of the limitations of these therapies mainly due to immunogenicity issues, toxicities associated with the infusion of the product, and relapses of the tumor. As a result, novel approaches are appearing aiming to solve and/or mitigate the harmful effects of CAR-T therapies. These include strategies based on the use of ligands as binding moieties or ligand-based CAR-T cells. Several proposals are currently under development

Angiogenesis and Anti-Angiogenic Treatment in Prostate Cancer: Mechanisms of Action and Molecular Targets.

Prostate cancer (PC) is the most common cancer in men and the second leading cause of cancer-related death worldwide. Many therapeutic advances over the last two decades have led to an improvement in the survival of patients with metastatic PC, yet the majority of these patients still succumb to their disease. Antiagiogenic therapies have shown substantial benefits for many types of cancer but only a marginal benefit for PC. Ongoing clinical trials investigate antiangiogenic monotherapies or combination therapies. Despite the important role of angiogenesis in PC, clinical trials in refractory

Natural and semisynthetic candidate molecules for COVID-19 prophylaxis and treatment.

Coronaviruses (CoVs) represent a family of viruses that have numerous animal hosts, and they cause severe respiratory, as well as systemic and enteric infections, in humans. Currently, there are limited antiviral strategies for treating patients infected with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The lack of specific antiviral medicines and SARS-CoV-2 vaccines continues to aggravate the situation. Natural product-based antiviral drugs have been used in the two previous CoV outbreaks: Middle East respiratory syndrome coronavirus (MERS-CoV) and the first SARS-CoV. This re

Myeloma Bone Disease: Update on Pathogenesis and Novel Treatment Strategies.

Bone disease, including osteolytic lesions and/or osteoporosis, is a common feature of multiple myeloma (MM). The consequences of skeletal involvement are severe pain, spinal cord compressions, and bone fractures, which have a dramatic impact on patients' quality of life and, ultimately, survival. During the past few years, several landmark studies significantly enhanced our insight into MM bone disease (MBD) by identifying molecular mechanisms leading to increased bone resorption due to osteoclast activation, and decreased bone formation by osteoblast inhibition. Bisphosphonates were the main

Overhauling CAR T Cells to Improve Efficacy, Safety and Cost.

Gene therapy is now surpassing 30 years of clinical experience and in that time a variety of approaches has been applied for the treatment of a wide range of pathologies. While the promise of gene therapy was over-stated in the 1990's, the following decades were met with polar extremes between demonstrable success and devastating setbacks. Currently, the field of gene therapy is enjoying the rewards of overcoming the hurdles that come with turning new ideas into safe and reliable treatments, including for cancer. Among these modalities, the modification of T cells with chimeric antigen recepto

Адипоцитный β-гидроксибутират обеспечивает метаболическую стойкость в множестве миеломы.

Множественная миелома (ММ) остается неизлечимым раком крови. Ожирение является известным фактором риска, но то, как адипоциты способствуют прогрессу MM, не в полной мере понятно. Здесь мы обнаруживаем метаболический перекресток между адипоцитами и клетками MM, который способствует выживанию клеток MM под глюкозой. Мы показываем, что ограничение глюкозы активирует АМПК, срывает связь HSP90-IRF4 и делает IRF4 восприимчивым к протеасомной деградации при помощи TRIM21. Парадоксально, но такой же стресс стимулирует адипоциты к производству β-гидроксибутирата (β-OHB). Клетки MM используют β-OHB при
