Histone Modifier KANSL2 является практически осуществимым биомаркером в Мультимиломе.

Эпигенетические отклонения являются ключевыми движущими силами множественной миеломы, однако адресная терапия, использующая эпигенетические изменения, еще не установлена. Объединяя клинические и молекулярные наборы пациентов с множественной миеломой с непредвзятым генетическим экраном в vivo, мы определили подгруппу 2 (KANSL2) КАТ8, регулирующую комплекс NSL, как гистонную послетрансляционную модификацию, связанную с онкогене. Высокое выражение KANSL2 было связано с неблагоприятным прогнозом у пациентов с множественной миеломой. Генетические модели " наживы " и " потери функцион

Long-term stabilisation of myeloma with curcumin.

Myeloma is a haematological malignancy which typically follows a relapsing-remitting course. While treatment can control the myeloma and improve quality of life for given periods of time, remissions generally become progressively shorter with subsequent relapses, and patients ultimately enter a final refractory phase. To help control symptoms and enhance quality of life, some patients use complementary therapies as an adjunct to their conventional therapy. Here, we describe a myeloma patient who started a daily dietary supplement of curcumin when approaching her third relapse. In the absence o

Multiple myeloma: clinical characteristics, current therapies and emerging innovative treatments targeting ribosome biogenesis dynamics.

Multiple myeloma (MM) is a clinical disorder characterized by aberrant plasma cell growth in the bone marrow microenvironment. Globally, the prevalence of MM has been steadily increasing at an alarming rate. In the United States, more than 30,000 cases will be diagnosed in 2024 and it accounts for about 2% of cancer diagnoses and more than 2% of cancer deaths, more than double the worldwide figure. Both symptomatic and active MM are distinguished by uncontrolled plasma cell growth, which results in severe renal impairment, anemia, hypercalcemia, and bone loss. Multiple drugs have been approved

Кетогенные изменения в метаболизме печени с потенциальными последствиями для озанимодных фармакокинетических мышей.

Кетогенное питание (КД) все чаще рассматривается в качестве адъюнктивного терапевтического подхода к целому ряду заболеваний, однако его воздействие на фармакокинетику сопутствующих лекарств остается неясным. Такое взаимодействие может иметь особое значение в случае множественного склероза, когда КД изучается в качестве дополнительной стратегии наряду с лечением заболеваний, например, озанимодом. Поэтому мы изучили вопрос о том, влияет ли KD на озанимодный метаболизм и фармакокинетику, и изучили потенциальные факторы, которые могут способствовать такому воздействию. Женщинам, не содержащим пат

Analysis of microRNA expression profiles in exosomes derived from acute myeloid leukemia by p62 knockdown and effect on angiogenesis.

ObjectivesIn this study, we aimed to investigate the effect of p62 on angiogenesis and microRNA (miRNA) expression profiles in acute myeloid leukemia (AML) exosomes.MethodsAn Exiqon v19.0 microRNA MicroArray was used to profile miRNAs in exosomes derived from parental and p62-knockdown U937 cells. The Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) databases were used to predict the biological functions and potential mechanisms of differentially expressed miRNAs in AML exosomes. Endothelial cell tube formation assays using human umbilical vein endothelial cells (HUVECs) w

Direct Endoplasmic Reticulum Targeting by the Selective Alkylphospholipid Analog and Antitumor Ether Lipid Edelfosine as a Therapeutic Approach in Pancreatic Cancer.

Pancreatic ductal adenocarcinoma (PDAC), the most common malignancy of the pancreas, shows a dismal and grim overall prognosis and survival rate, which have remained virtually unchanged for over half a century. PDAC is the most lethal of all cancers, with the highest mortality-to-incidence ratio. PDAC responds poorly to current therapies and remains an incurable malignancy. Therefore, novel therapeutic targets and drugs are urgently needed for pancreatic cancer treatment. Selective induction of apoptosis in cancer cells is an appealing approach in cancer therapy. Apoptotic cell death is highly

A 3D engineered multiple myeloma niche for evaluating CAR T cell therapy.

Chimeric antigen receptor (CAR) T cell therapies targeting B cell maturation antigen (BCMA) have shown unprecedented success in treating multiple myeloma (MM), yet long-term relapse remains a critical challenge, possible due to the protective influence of the bone marrow (BM) microenvironment. Current in vitro models often rely on simplistic 2D cocultures of CAR T and MM cells, and fail to recapitulate the 3D structural and cellular complexity of the osteogenic niche, which is known to facilitate immune evasion. In this study, we aimed to develop a physiologically relevant 3D in vitro MM model

Advances in Gold Nanoparticle-Based Combined Cancer Therapy.

According to the global cancer observatory (GLOBOCAN), there are approximately 18 million new cancer cases per year worldwide. Cancer therapies are largely limited to surgery, radiotherapy, and chemotherapy. In radiotherapy and chemotherapy, the maximum tolerated dose is presently being used to treat cancer patients. The integrated development of innovative nanoparticle (NP) based approaches will be a key to address one of the main issues in both radiotherapy and chemotherapy: normal tissue toxicity. Among other inorganic NP systems, gold nanoparticle (GNP) based systems offer the means to fur

Solamargine induces autophagy-mediated apoptosis and enhances bortezomib activity in multiple myeloma.

Multiple myeloma (MM) is an incurable plasma cell malignancy with a poor survival rate. Conventional chemotherapeutic agent-induced adverse events, including toxicity, neuropathy or drug resistance, significantly decrease the patients' quality of life and can even lead to interruption of treatment. Therefore, novel therapeutic drugs and strategies are urgently needed to improve MM therapy and patient outcomes. Here, we show that solamargine (SM), a steroidal alkaloid glycoside isolated from a Chinese herb Solanum nigrum L., exhibits promising anti-MM activity. In particular, SM suppressed the

Mobilizing stem cells and inhibition of autoimmunity synergistically modify autoimmune disease to relieve pain: a potential MRG-001 therapy for rheumatoid arthritis.

OBJECTIVES: Rheumatoid arthritis (RA) is a chronic autoimmune disease characterized by persistent synovial inflammation, bone erosion, cartilage destruction, and debilitating pain. Current therapies often fall short in preventing structural damage and restoring immune balance. To address these limitations, we evaluated MRG-001 - a fixed-dose combination of plerixafor (AMD3100) and low-dose tacrolimus (FK506) with reported immunoregulatory and regenerative potential - in preclinical models of RA. METHODS: The therapeutic efficacy of MRG-001 was assessed in collagen-induced arthritis and collag

Real world data on light chain cardiac amyloidosis: Still a delayed diagnosis.

Cardiac amyloidosis (CA) represents a myocardial disorder developed by fibril deposition of a heterogeneous group of misfolding proteins. Despite being rare, a high clinical index of suspicion and novel advanced diagnostic methods seem to facilitate its early recognition. Currently nine types of cardiac amyloidosis have been described with AL and ATTR being the most common. Light chain amyloidosis (AL) is a life-threatening disease, resulting from clonal plasma cells that produce amyloidogenic light chain fragments causing organ damage including the heart. Morbidity and mortality of these pati

Alu-dependent RNA editing of GLI1 promotes malignant regeneration in multiple myeloma.

Despite novel therapies, relapse of multiple myeloma (MM) is virtually inevitable. Amplification of chromosome 1q, which harbors the inflammation-responsive RNA editase adenosine deaminase acting on RNA (ADAR)1 gene, occurs in 30-50% of MM patients and portends a poor prognosis. Since adenosine-to-inosine RNA editing has recently emerged as a driver of cancer progression, genomic amplification combined with inflammatory cytokine activation of ADAR1 could stimulate MM progression and therapeutic resistance. Here, we report that high ADAR1 RNA expression correlates with reduced patient survival

In Vivo and In Vitro Pharmacokinetic Studies of a Dual Topoisomerase I/II Inhibitor.

Due to high mortality rates, new and more effective drugs are urgently needed in cancer therapy. The novel dual topoisomerase inhibitor P8-D6, a dimethylaminoethyl-substituted pyridophenanthroline, showed in vitro impressive induction of apoptosis in tumors such as ovarian cancer or multiple myeloma compared to the current standard therapy. The purpose of this study was to investigate its in vitro and in vivo pharmacokinetics and to discover further potential drug candidates. Samples of plasma, various tissues, urine, feces, and cell culture supernatants were examined by HPLC. In addition, the

Minimal Residual Disease in Acute Lymphoblastic Leukemia: Technical and Clinical Advances.

Introduction: Acute lymphoblastic leukemia (ALL) is the first neoplasm where the assessment of early response to therapy by minimal residual disease (MRD) monitoring has proven to be a fundamental tool to guide therapeutic choices. The most standardized methods to study MRD in ALL are multi-parametric flow cytometry (MFC) and polymerase chain reaction (PCR) amplification-based methods. Emerging technologies hold the promise to improve MRD detection in ALL patients. Moreover, novel therapies, such as monoclonal antibodies, bispecific T-cell engagers, and chimeric antigen receptor T cells (CART)
