Versatility of 14-3-3 proteins and their roles in bone and joint-related diseases.

Bone and joint-related diseases, including osteoarthritis (OA), rheumatoid arthritis (RA), and bone tumors, pose significant health challenges due to their debilitating effects on the musculoskeletal system. 14-3-3 proteins, a family of conserved regulatory molecules, play a critical role in the pathology of these diseases. This review discusses the intricate structure and multifunctionality of 14-3-3 proteins, their regulation of signaling pathways, and their interactions with other proteins. We underscore the significance of 14-3-3 proteins in the regulation of osteoblasts, osteoclasts, chon

RVd и CyBord терапии ремоделируют созревание клеток B и изменяют иммунную и клональную архитектуру в множестве миеломы.

Множественная миелома (ММ) характеризуется неоднородностью плазменных клеток (ПХ) и изменениями в дифференциации В-клеток и иммунной регламентации. Хотя линалидомид/бортезомиб/дексатон (RV) и циклофосфамид/бортезомиб/дексамасон (CyBorD) являются клинически эффективными, их точное воздействие на созревание ПК/B-клеток остается неясным.

New Avenues and Major Achievements in Phytocompounds Research for Glioblastoma Therapy.

Phytocompounds have been evaluated for their anti-glioblastoma actions for decades, with promising results from preclinical studies but only limited translation into clinics. Indeed, by targeting multiple signaling pathways deregulated in cancer, they often show high efficacy in the in vitro studies, but their poor bioavailability, low tumor accumulation, and rapid clearance compromise their efficacy in vivo. Here, we present the new avenues in phytocompound research for the improvement of glioblastoma therapy, including the ways to enhance the response to temozolomide using phytochemicals, th

Bispecific and multispecific immune engagers for redirecting innate and adaptive immunity against hematologic cancers.

Bispecific antibodies (BsAbs) and multispecific antibodies (MsAbs) represent a transformative class of immunotherapeutics in oncology. These engineered molecules possess the unique ability to simultaneously target two or more distinct antigens, thereby facilitating precise immune cell engagement and disrupting multiple signaling pathways. This comprehensive review focuses on their pivotal role in redirecting both innate (natural killer cells, phagocytes) and adaptive (T cells) immunity, with a particular emphasis on their application against hematologic cancers. Significant clinical successes,

The cross talk of ubiquitination and chemotherapy tolerance in colorectal cancer.

Ubiquitination, a highly adaptable post-translational modification, plays a pivotal role in maintaining cellular protein homeostasis, encompassing cancer chemoresistance-associated proteins. Recent findings have indicated a potential correlation between perturbations in the ubiquitination process and the emergence of drug resistance in CRC cancer. Consequently, numerous studies have spurred the advancement of compounds specifically designed to target ubiquitinates, offering promising prospects for cancer therapy. In this review, we highlight the role of ubiquitination enzymes associated with c

The Undervalued Avenue to Reinstate Tumor Suppressor Functionality of the p53 Protein Family for Improved Cancer Therapy-Drug Repurposing.

p53 and p73 are critical tumor suppressors that are often inactivated in human cancers through various mechanisms. Owing to their high structural homology, the proteins have many joined functions and recognize the same set of genes involved in apoptosis and cell cycle regulation. p53 is known as the 'guardian of the genome' and together with p73 forms a barrier against cancer development and progression. The TP53 is mutated in more than 50% of all human cancers and the germline mutations in TP53 predispose to the early onset of multiple tumors in Li-Fraumeni syndrome (LFS), the inherited cance

Rejuvenation Strategy for Inducing and Enhancing Autoimmune Response to Eliminate Senescent Cells.

The process of aging, which involves progressive changes in the body over time, is closely associated with the development of age-related diseases. Cellular senescence is a pivotal hallmark and mechanism of the aging process. The accumulation of senescent cells can significantly contribute to the onset of age-related diseases, thereby compromising overall health. Conversely, the elimination of senescent cells enhances the body's regenerative and reparative capacity, thereby retarding the aging process. Here, we present a brief overview of 12 Hallmarks of aging and subsequently emphasize the po

Combination Therapy With Histone Deacetylase Inhibitors (HDACi) for the Treatment of Cancer: Achieving the Full Therapeutic Potential of HDACi.

Genetic and epigenetic changes in DNA are involved in cancer development and tumor progression. Histone deacetylases (HDACs) are key regulators of gene expression that act as transcriptional repressors by removing acetyl groups from histones. HDACs are dysregulated in many cancers, making them a therapeutic target for the treatment of cancer. Histone deacetylase inhibitors (HDACi), a novel class of small-molecular therapeutics, are now approved by the Food and Drug Administration as anticancer agents. While they have shown great promise, resistance to HDACi is often observed and furthermore, H

Epidemiology, genetics and treatment of multiple myeloma and precursor diseases.

Multiple myeloma (MM) is a hematological malignancy caused by the clonal expansion of plasma cells. The incidence of MM worldwide is increasing with greater than 140 000 people being diagnosed with MM per year. Whereas 5-year survival after a diagnosis of MM has improved from 28% in 1975 to 56% in 2012, the disease remains essentially incurable. In this review, we summarize our current understanding of MM including its epidemiology, genetics and biology. We will also provide an overview of MM management that has led to improvements in survival, including recent changes to diagnosis and therapi

Interpreting clinical assays for histone deacetylase inhibitors.

As opposed to genetics, dealing with gene expressions by direct DNA sequence modifications, the term epigenetics applies to all the external influences that target the chromatin structure of cells with impact on gene expression unrelated to the sequence coding of DNA itself. In normal cells, epigenetics modulates gene expression through all development steps. When "imprinted" early by the environment, epigenetic changes influence the organism at an early stage and can be transmitted to the progeny. Together with DNA sequence alterations, DNA aberrant cytosine methylation and microRNA deregulat

Sestrin-2: a new biomarker for type 2 Diabetes Mellitus and Insulin resistance.

Multiple myeloma (MM) is the second most common haematological malignancy characterised by clonal proliferation of plasma cells within the bone marrow. Despite advances in treatment options, myeloma remains incurable. Relapsed MM poses significant challenges due to clonal evolution, drug resistance, patient comorbidities and therefore complexities of therapeutic decision-making. A critical question in managing relapsed MM is whether to switch drug classes or retreat with agents within the same class. The question is present with the recent addition of three new drug classes (XPO1 inhibitors, B

Proteasome inhibition protects blood-brain barrier P-glycoprotein and lowers Aβ brain levels in an Alzheimer's disease model.

BackgroundLoss of P-glycoprotein (P-gp) at the blood-brain barrier contributes to amyloid-β (Aβ) brain accumulation in Alzheimer's disease (AD). Using transgenic human amyloid precursor protein (hAPP)-overexpressing mice (Tg2576), we previously showed that Aβ triggers P-gp loss by activating the ubiquitin-proteasome pathway, which leads to P-gp degradation. Furthermore, we showed that inhibiting the ubiquitin-activating enzyme (E1) prevents P-gp loss and lowers Aβ accumulation in the brain of hAPP mice. Based on these data, we hypothesized that repurposing the FDA-approved proteasome inhibitor

T-Regulatory Cells In Tumor Progression And Therapy.

Regulatory T cells (Tregs) are important members of the immune system regulating the host responses to infection and neoplasms. Tregs prevent autoimmune disorders by protecting the host-cells from an immune response, related to the peripheral tolerance. However, tumor cells use Tregs as a shield to protect themselves against anti-tumor immune response. Thus, Tregs are a hurdle in achieving the complete potential of anti-cancer therapies including immunotherapy. This has prompted the development of novel adjuvant therapies that obviate their negative effects thereby enhancing the therapeutic ef

The Gut-Bone Marrow Axis: Deciphering the Mechanistic Impact of Microbial Metabolites on Hematopoietic Homeostasis and Disorders.

The gut microbiota is increasingly recognized as a dynamic endocrine-like microbial network that exerts systemic effects far beyond the gastrointestinal tract. Emerging evidence supports the existence of a "gut-bone marrow axis" through which gut-derived signals orchestrate hematopoietic homeostasis. However, shifting from correlative observations to causal mechanisms remains a major challenge in defining precise microbial impacts on hematopoietic outcomes. In this review, we systematically synthesize current knowledge on the molecular mechanisms by which microbial products-specifically short-

Therapeutic Potential of Chlorogenic Acid in Chemoresistance and Chemoprotection in Cancer Treatment.

Chemotherapeutic drugs are indispensable in cancer treatment, but their effectiveness is often lessened because of non-selective toxicity to healthy tissues, which triggers inflammatory pathways that are harmful to vital organs. In addition, tumors' resistance to drugs causes failures in treatment. Chlorogenic acid (5-caffeoylquinic acid, CGA), found in plants and vegetables, is promising in anticancer mechanisms. In vitro and animal studies have indicated that CGA can overcome resistance to conventional chemotherapeutics and alleviate chemotherapy-induced toxicity by scavenging free radicals
