Pathophysiology and therapeutic advances in myeloma bone disease.

Bone disease is the most common complication in patients with multiple myeloma (MM), and it may lead to skeletal-related events (SREs) such as bone pain, pathological fractures, and spinal cord compression, which impair a patients' quality of life and survival. The pathogenesis of myeloma bone disease (MBD) involves disruption of bone reconstitution balance including excessive activation of osteoclasts, inhibition of osteoblasts, and participation of osteocytes and bone marrow stromal cells. Various factors, such as the receptor activator of nuclear factor-κB ligand (RANKL)/osteoprotegerin (OP

A case-control study of prevalence of anemia among patients with type 2 diabetes.

BackgroundAnemia is defined as a reduction in the hemoglobin concentration of blood, which consequently reduces the oxygen-carrying capacity of red blood cells such that they are unable to meet the body's physiological needs. Several reports have indicated that anemia mostly occurs in patients with diabetes with renal insufficiency while limited studies have reported the incidence of anemia in people with diabetes prior to evidence of renal impairment. Other studies have also identified anemia as a risk factor for the need for renal replacement therapy in diabetes. Understanding the pathogenes

Short-chain fatty acids in the tumor microenvironment: from molecular mechanisms to cancer therapy.

Short-chain fatty acids (SCFAs), including acetate, propionate, and butyrate, serve as pivotal metabolites within the tumor microenvironment (TME), playing essential roles in modulating tumor progression. Although the biological functions and mechanisms of SCFAs in the TME show some overlap, each SCFA also exerts some distinct regulatory effects on tumors and TME. Notably, even a single SCFA may exhibit pleiotropic effects across different cancer types or under varying conditions within the same malignancy. Consequently, according to the different metabolic microenvironment of patients, precis

Облученные CD19 химерик антигенные рецепторы YTS клетки сохраняют антитуматорную активность и предлагают масштабируемую альтернативу аутологической терапии CAR-T.

Химерическая антигенная рецепторная (CAR) терапия клеток революционизировала лечение таких гематологов, как лимфома и множественная миелома. Однако их успех ограничивается высокими производственными издержками, зависимостью от аутологических Т клеток, переменным качеством продукта и такими опасными для жизни токсичными свойствами, как синдром выброса цитокина. В отличие от этого клетки естественного убийцы (НК) предлагают более безопасную, более гибкую альтернативу, однако их клинический перевод по-прежнему сдерживается сложными протоколами расширения и высокими производственными издержками.

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

An immunotherapeutic approach to decipher the role of long non-coding RNAs in cancer progression, resistance and epigenetic regulation of immune cells.

Immunotherapeutic treatments are gaining attention due to their effective anti-tumor response. Particularly, the revolution of immune checkpoint inhibitors (ICIs) produces promising outcomes for various cancer types. However, the usage of immunotherapy is limited due to its low response rate, suggesting that tumor cells escape the immune surveillance. Rapid advances in transcriptomic profiling have led to recognize immune-related long non-coding RNAs (LncRNAs), as regulators of immune cell-specific gene expression that mediates immune stimulatory as well as suppression of immune response, indi

Recent Advances in Understanding the Mechanisms of Elemene in Reversing Drug Resistance in Tumor Cells: A Review.

Malignant tumors are life-threatening, and chemotherapy is one of the common treatment methods. However, there are often many factors that contribute to the failure of chemotherapy. The multidrug resistance of cancer cells during chemotherapy has been reported, since tumor cells' sensitivity decreases over time. To overcome these problems, extensive studies have been conducted to reverse drug resistance in tumor cells. Elemene, an extract of the natural drug Curcuma wenyujin, has been found to reverse drug resistance and sensitize cancer cells to chemotherapy. Mechanisms by which elemene rever

Epigenetic regulation in gynecological cancers: a paradigm shift in immunotherapy strategies.

Recent advances in immunotherapy have transformed the therapeutic landscape of gynecological cancers; however, durable responses remain limited by tumor heterogeneity and immune evasion mechanisms. Emerging evidence highlights epigenetic modifications comprising of DNA methylation, histone modifications, and RNA methylation as pivotal regulators of the tumor immune microenvironment and immunotherapy efficacy.

Histone deacetylase upregulation of neuropilin-1 in osteosarcoma is essential for pulmonary metastasis.

The lungs represent the most common site of metastasis for osteosarcoma (OS). Despite our advances in developing targeted therapies for treating solid malignancies, broad acting chemotherapies remain the first line treatment for OS. In assaying the efficacy of approved therapeutics for non-OS malignancies, we previously identified the histone deacetylase 1 and 2 (HDAC1 and 2) inhibitor, romidepsin, as effective for the treatment of established lung metastatic OS. Yet, romidepsin has noted toxicities in humans and so here we aimed to define the primary mechanisms through which HDAC1/2 mediate O

Extracellular vesicles: a new frontier in diagnosing and treating graft-versus-host disease after allogeneic hematopoietic cell transplantation.

Graft-versus-host disease (GvHD) is a prevalent complication following allogeneic hematopoietic stem cell transplantation (HSCT) and is characterized by relatively high morbidity and mortality rates. GvHD can result in extensive systemic damage in patients following allogeneic HSCT (allo-HSCT), with the skin, gastrointestinal tract, and liver frequently being the primary target organs affected. The severe manifestations of acute intestinal GvHD often indicate a poor prognosis for patients after allo-HSCT. Endoscopy and histopathological evaluation remain employed to diagnose GvHD, and auxiliar

Understanding Aberrant Signaling to Elude Therapy Escape Mechanisms in Myeloproliferative Neoplasms.

Aberrant signaling in myeloproliferative neoplasms may arise from alterations in genes coding for signal transduction proteins or epigenetic regulators. Both mutated and normal cells cooperate, altering fragile balances in bone marrow niches and fueling persistent inflammation through paracrine or systemic signals. Despite the hopes placed in targeted therapies, myeloid proliferative neoplasms remain incurable diseases in patients not eligible for stem cell transplantation. Due to the emergence of drug resistance, patient management is often very difficult in the long term. Unexpected connecti

Metabolic crosstalk between stromal and malignant cells in the bone marrow niche.

Bone marrow is the primary site of blood cell production in adults and serves as the source of osteoblasts and osteoclasts that maintain bone homeostasis. The medullary microenvironment is also involved in malignancy, providing a fertile soil for the growth of blood cancers or solid tumors metastasizing to bone. The cellular composition of the bone marrow is highly complex, consisting of hematopoietic stem and progenitor cells, maturing blood cells, skeletal stem cells, osteoblasts, mesenchymal stromal cells, adipocytes, endothelial cells, lymphatic endothelial cells, perivascular cells, and n

BCMA-Targeting Therapy: Driving a New Era of Immunotherapy in Multiple Myeloma.

The treatment of multiple myeloma (MM) has entered into a new era of immunotherapy. Novel immunotherapies will significantly improve patient outcome via simultaneously targeting malignant plasma cell (PC) and reversing immunocompromised bone marrow (BM) microenvironment. B-cell maturation antigen (BCMA), selectively expressed in PCs and a key receptor for A proliferation-inducing ligand (APRIL), is highly expressed in MM cells from patients at all stages. The APRIL/BCMA signal cascades promote the survival and drug resistance of MM cells and further modulate immunosuppressive BM milieu. Impres
