Targeting Histone Deacetylases: Opportunities for Cancer Treatment and Chemoprevention.

The dysregulation of gene expression is a critical event involved in all steps of tumorigenesis. Aberrant histone and non-histone acetylation modifications of gene expression due to the abnormal activation of histone deacetylases (HDAC) have been reported in hematologic and solid types of cancer. In this sense, the cancer-associated epigenetic alterations are promising targets for anticancer therapy and chemoprevention. HDAC inhibitors (HDACi) induce histone hyperacetylation within target proteins, altering cell cycle and proliferation, cell differentiation, and the regulation of cell death pr

JunB is a key regulator of multiple myeloma bone marrow angiogenesis.

Bone marrow (BM) angiogenesis significantly influences disease progression in multiple myeloma (MM) patients and correlates with adverse prognosis. The present study shows a statistically significant correlation of the AP-1 family member JunB with VEGF, VEGFB, and IGF1 expression levels in MM. In contrast to the angiogenic master regulator Hif-1α, JunB protein levels were independent of hypoxia. Results in tumor-cell models that allow the induction of JunB knockdown or JunB activation, respectively, corroborated the functional role of JunB in the production and secretion of these angiogenic fa

Bone fragility and osteoporosis in children and young adults.

Osteoporosis is a metabolic bone disorder which increases fragility fracture risk. Elderly individuals, especially postmenopausal women, are particularly susceptible to osteoporosis. Although rare, osteoporosis in children and young adults is becoming increasingly evident, highlighting the need for timely diagnosis, management and follow-up. Early-onset osteoporosis is defined as the presence of a low BMD (Z-score of ≤ -2.0 in individuals aged < 20 years; T-score of ≤ -2.5 in those aged between 20 to 50 years) accompanied by a clinically significant fracture history, or the presence of low-ene

Тонаберсат усиливает цитотоксичность в глиобластоме с помощью темозоломида путем нарушения межклеточной связи через коннексин 43 ингибирование.

Клетки глиобластомы зависят от коннексина 43 (Cx43) на основе данных о разрыве (GJs) для межклеточной связи, позволяющей им интегрироваться в широко разветвленную злокачественную сеть. Несмотря на многообещающие перспективы новой целевой терапии, отсутствие клинически осуществимых ингибиторов GJ препятствует их внедрению в клинической практике. В настоящем исследовании мы изучили тонаберсат (ТО) — лекарство, вызывающее кровоизлияние в мозг и имеющее свойства GJ-ингиберия, с точки зрения его способности разобрать межклеточную связь в сетях глиобластомы. Для изучения функциональной межклеточной

Current Approaches in the Treatment of Relapsed and Refractory Acute Myeloid Leukemia.

The limited sensitivity of the historical treatment response criteria for acute myeloid leukemia (AML) has resulted in a different paradigm for treatment compared with most other cancers presenting with widely disseminated disease. Initial cytotoxic induction chemotherapy is often able to reduce tumor burden to a level sufficient to meet the current criteria for "complete" remission. Nevertheless, most AML patients ultimately die from their disease, most commonly as clinically evident relapsed AML. Despite a variety of available salvage therapy options, prognosis in patients with relapsed or r

Cancer stem cells in esophageal squamous cell cancer.

Cancer stem cells (CSCs) are hypothesized to govern the origin, progression, drug resistance, recurrence and metastasis of human cancer. CSCs have been identified in nearly all types of human cancer, including esophageal squamous cell cancer (ESCC). Four major methods are typically used to isolate or enrich CSCs, including: i) fluorescence-activated cell sorting or magnetic-activated cell sorting using cell-specific surface markers; ii) stem cell markers, including aldehyde dehydrogenase 1 family member A1; iii) side population cell phenotype markers; and iv) microsphere culture methods. ESCC

Nanoparticle Strategies for Bone Metastasis Immunotherapy: Targeting, Immune Reprogramming and Combination Therapy.

Bone metastases remain one of the most clinically devastating complications of advanced cancer, particularly in breast, prostate, and lung malignancies, where they drive pain, fractures, hypercalcemia, and progressive functional decline. Their management is further complicated by a highly immunosuppressive bone microenvironment characterized by osteoclast-driven bone destruction, myeloid cell dominance, impaired antigen presentation, and weak effector T-cell infiltration, all of which limit the activity of conventional immunotherapies. In this setting, nanoparticles are emerging not merely as

Current Status and Perspectives of Protease Inhibitors and Their Combination with Nanosized Drug Delivery Systems for Targeted Cancer Therapy.

In cancer treatments, many natural and synthetic products have been examined; among them, protease inhibitors are promising candidates for anti-cancer agents. Since dysregulated proteolytic activities can contribute to tumor development and metastasis, antagonization of proteases with tailored inhibitors is an encouraging approach. Although adverse effects of early designs of these inhibitors disappeared after the introduction of next-generation agents, most of the proposed inhibitors did not pass the early stages of clinical trials due to their nonspecific toxicity and lack of pharmacological

Recent advances in the management of older adults with newly diagnosed multiple myeloma in Japan.

Multiple myeloma is a cancer of plasma cells; the incidence rate of multiple myeloma is high among older adults. Although significant advances have been made in the clinical management of multiple myeloma driven by the introduction of novel drugs, such as proteasome inhibitors, immuno- modulators and antibodies, multiple myeloma remains incurable. Hence, the current therapeutic goal for multiple myeloma is to achieve long-term survival while maintaining a good quality of life. In this context, personalized treatment to balance the efficacy and safety of therapies is important, especially for o
