Erythropoiesis-Stimulating Agents in the Management of Anemia in Chronic Kidney Disease or Cancer: A Historical Perspective.

Anemia is common in patients with cancer or with chronic kidney disease (CKD). Although the introduction of erythropoiesis-stimulating agents (ESAs) has transformed the management of anemia, their use has been complicated by a number of factors including frequent guideline updates, safety concerns and, in the United States, a Risk Evaluation and Mitigation Strategy (REMS) program, which aimed to ensure that the benefits of ESAs outweigh the risks. Many previous concerns around ESA use in cancer and CKD have been addressed by the reassuring results of post-approval studies, and biosimilar ESAs

Ирисин предотвращает повреждение трабекулярных костей и проникновение опухоли в мышиную модель множественной миэломы.

Болезни костей, связанные с множественной миеломой (ММ), характеризуются остеолитическими повреждениями и патологическими переломами, которые по-прежнему являются приоритетной терапевтической задачей, несмотря на новые лекарственные средства, способствующие выживанию пациентов с MM. Антирезорптивные молекулы представляют собой главный вариант лечения костного заболевания, связанного с MM (MMBD), в то время как остеоанаболические молекулы в настоящее время изучаются. Среди последних мы здесь сосредоточили внимание на миокиновом ирисине, который способен увеличить массу костей в здоровых мышах,

Неинвазивный визуальный тета модифицирует связанные с миэлином и функциональные результаты в модели демиэлирования, вызванной LPC.

Демиелинация является отличительной чертой различных нейродегенеративных заболеваний, включая множественный склероз (MS), приводящий к поврежденной нейронной трансмиссии и дефициту двигателя. Модель демиелинации, вызванная лизофоспатидилхолином (LPC), широко используется, поскольку она отражает многие аспекты демиелинизирующей патологии. В ходе этого исследования было изучено, как неинвазивное воздействие 4 Гц на визуальную осцилляцию тета, вызванную ЛПК, влияет на обезвоживание в оптическом хиазме самцов мышей C57BL/6J. Мыши ежедневно получали одночасовые сеансы стимуляции 4 Гц в течение двух

LAP2α drives breast tumorigenesis by mitigating replication stress.

Replication protein A (RPA) plays a vital role in replication stress response, with RPA-coated single-stranded DNA (ssDNA) acting as a critical platform for the coordination of the genome surveillance machinery. In previous studies, we reported that the lamin-associated protein LAP2α interacts physically with RPA, aiding its localization to damaged chromatin for genome protection. However, the significance of the LAP2α-mediated RPA deposition in tumor progression remains unclear. Here, we reveal that LAP2α promotes breast tumorigenesis by counteracting replication stress-induced DNA damage. Fu

Диметилфумарат (ДМП) и его первичный активный метаболит монометилфумарат (ММФ) являются активаторами Nrf2 и признаны в качестве стратегических антиоксидантов. Цель этого исследования состояла в том, чтобы оценить потенциал MMF и DMF в плане воздействия на адипогенез и ожирение, а также выявить соответствующие молекулярные механизмы. Предадипоциты 3T3-L1 были инкубированы с дифференциальной среды (MIX) и одновременно обработаны различными концентрациями MMF.

Radiotherapy plus CAR-T cell therapy to date: A note for cautions optimism?

Radiotherapy (RT) is a traditional therapeutic regime that focuses on ionizing radiation, however, RT maintains largely palliative due to radioresistance. Factors such as hypoxia, the radiosensitivity of immune cells, and cancer stem cells (CSCs) all come into play in influencing the significant impact of radioresistance in the irradiated tumor microenvironment (TME). Due to the substantial advances in the treatment of malignant tumors, a promising approach is the genetically modified T cells with chimeric antigen receptors (CARs) to eliminate solid tumors. Moreover, CAR-T cells targeting CSC-

Radiocopper in BCMA-targeted immunotheranostics of myeloma.

BACKGROUND: The theranostic potential of copper-64 (PET imaging) and copper-67 (SPECT imaging and therapy) is increasingly recognized. This work investigates the performance of this 'true' matched pair in a preclinical radioimmunotheranostic setting that utilizes experimental monoclonal antibodies (mAbs) directed against B cell maturation antigen (BCMA), a transmembrane glycoprotein that has emerged as a critical target for the treatment of multiple myeloma (MM). METHODS: The commercially available BCMA-directed mAbs MAB193 and Vicky-1 were modified with the bispidine N2py4 enabling chelation

Penfluridol inhibits melanoma growth and metastasis through enhancing von Hippel‒Lindau tumor suppressor-mediated cancerous inhibitor of protein phosphatase 2A (CIP2A) degradation.

Melanoma's high metastatic potential, especially to the brain, poses significant challenges to patient survival. The blood‒brain barrier (BBB) is a major obstacle to the effective treatment of melanoma brain metastases. We screened antipsychotic drugs capable of crossing the BBB and identified penfluridol (PF) as the most active candidate. PF reduced melanoma cell viability and induced apoptosis. In animal models, PF effectively inhibited melanoma growth and metastasis to the lung and brain. Using immunoprecipitation combined with high-resolution mass spectrometry, and other techniques such as

Animal Models in Rheumatoid Arthritis: Is There a Correlation Between Autoantibodies in Human Pathology and Animal Models?

RA is a chronic autoimmune disease characterized by synovial inflammation and joint damage, driven by autoantibodies such as ACPA, anti-CarP and RF. These autoantibodies, influenced by genetic and environmental factors, play a crucial role in RA pathogenesis through post-translational modifications like citrullination, carbamylation, and acetylation. The early detection of ACPA provides a potential window for intervention, while anti-CarP antibodies correlate with severe disease progression and RF aids in diagnosis. Translating these findings from human pathology to animal models presents sign

Protein Quality Control in Glioblastoma: A Review of the Current Literature with New Perspectives on Therapeutic Targets.

Protein quality control allows eukaryotes to maintain proteostasis under the stress of constantly changing conditions. In this review, we discuss the current literature on PQC, highlighting flaws that must exist for malignancy to occur. At the nidus of PQC, the expression of BAG1-6 reflects the cell environment; each isoform directs proteins toward different, parallel branches of the quality control cascade. The sum of these branches creates a net shift toward either homeostasis or apoptosis. With an established role in ALP, Bag3 is necessary for cell survival in stress conditions including th

Mass Spectrometry Approaches for Identification and Quantitation of Therapeutic Monoclonal Antibodies in the Clinical Laboratory.

Therapeutic monoclonal antibodies (MAbs) are an important class of drugs used to treat diseases ranging from autoimmune disorders to B cell lymphomas to other rare conditions thought to be untreatable in the past. Many advances have been made in the characterization of immunoglobulins as a result of pharmaceutical companies investing in technologies that allow them to better understand MAbs during the development phase. Mass spectrometry is one of the new advancements utilized extensively by pharma to analyze MAbs and is now beginning to be applied in the clinical laboratory setting. The rise

Молекулярная основа для человеческой митохондриальной модификации tRNA m3C с помощью альтернативной разбрызгивания METTL8.

METTL8 недавно был определен как катализатор метилпереносазы 3-methylcytidine Биогенез на месте 32 (м3С32) митохондриальных tRNA. METTL8 также потенциально участвует в мRNA метилации и R-loop Biogenesis. Как METTL8 играет многообразную роль в разных камерах, и митохондриальное образование митохондриала tRNA m3C остается неясным. Здесь мы обнаружили, что альтернативное скрещивание mRNA вызвало несколько изоформ METTL8. One (изоформ)METTL8-Iso1) был направлен на митохондрию через N-терминальную предпоследнюю последовательность, в то время как другой one (В тыс.METTL8-Iso4) в основном локализован

Proteasome inhibitors - molecular basis and current perspectives in multiple myeloma.

Inhibition of proteasome, a proteolytic complex responsible for the degradation of ubiquitinated proteins, has emerged as a powerful strategy for treatment of multiple myeloma (MM), a plasma cell malignancy. First-in-class agent, bortezomib, has demonstrated great positive therapeutic efficacy in MM, both in pre-clinical and in clinical studies. However, despite its high efficiency, a large proportion of patients do not achieve sufficient clinical response. Therefore, the development of a second-generation of proteasome inhibitors (PIs) with improved pharmacological properties was needed. Rece

Proteasome 26S subunit, non-ATPases 1 (PSMD1) and 3 (PSMD3), play an oncogenic role in chronic myeloid leukemia by stabilizing nuclear factor-kappa B.

Tyrosine kinase inhibitors (TKIs) targeting BCR-ABL1 have revolutionized therapy for chronic myeloid leukemia (CML), paving the way for clinical development in other diseases. Despite success, targeting leukemic stem cells and overcoming drug resistance remain challenges for curative cancer therapy. To identify drivers of kinase-independent TKI resistance in CML, we performed genome-wide expression analyses on TKI-resistant versus sensitive CML cell lines, revealing a nuclear factor-kappa B (NF-κB) expression signature. Nucleocytoplasmic fractionation and luciferase reporter assays confirmed i

Pro-inflammatory cytokine-mediated anemia: regarding molecular mechanisms of erythropoiesis.

Anemia of cancer and chronic inflammatory diseases is a frequent complication affecting quality of life. For cancer patients it represents a particularly bad prognostic. Low level of erythropoietin is considered as one of the causes of anemia in these pathologies. The deficiency in erythropoietin production results from pro-inflammatory cytokines effect. However, few data is available concerning molecular mechanisms involved in cytokine-mediated anemia. Some recent publications have demonstrated the direct effect of pro-inflammatory cytokines on cell differentiation towards erythroid pathway,
