Comprehensive machine learning analysis of PANoptosis signatures in multiple myeloma identifies prognostic and immunotherapy biomarkers.

PANoptosis is closely associated with tumorigenesis and therapeutic response, yet its role in multiple myeloma (MM) remains unclear. This study analyzed bulk transcriptomic and clinical data from the TCGA and GEO databases to identify seven PANoptosis-related genes (PRGs) using machine learning (LASSO regression and random forest models) and univariate Cox analysis, and constructed a prognostic risk model. The model demonstrated robust predictive performance across three external validation cohorts. High-risk patients exhibited higher tumor purity, increased tumor mutational burden, and distin

Reactive oxygen species (ROS) in cancer: from mechanism to therapeutic implications.

Reactive oxygen species (ROS) act as critical secondary messengers in various intracellular signaling pathways that regulate cellular proliferation, differentiation, and survival under normal physiological conditions. However, dysregulation of redox signaling-driven by genetic mutations, epigenetic alterations, and posttranscriptional or posttranslational modifications-plays a central role in malignant transformation and cancer progression. Cancer cells typically exhibit elevated basal ROS levels due to increased metabolic activity, mitochondrial dysfunction, and oncogene activation. This mode

Воспламенительная ось LncRNA Ftx/miR-382-5p/NRG1 в дифференциальном диагностике и прогнозе множественного склероза и нейромелита Оптика.

Множественные склерозы (MS) и нейромиелитные оптики (NMO) представляют собой связанные с иммунизацией (CNS) подстрекательские заболевания, которые часто сопровождаются совпадающими клиническими симптомами, что часто приводит к неправильному диагностированию, особенно у пациентов с серонегативом NMO, страдающих аквапорином-4. Определение основополагающих механизмов этих заболеваний имеет решающее значение для обнаружения биомаркеров, позволяющих своевременно диагностировать и эффективно лечить. В этом исследовании приняли участие 252 участника, которые разделились на четыре группы. Группа I (Во

Диметил фумарат отменяет гепатоцеллюлярный карциномный рост, подавляя ось Nrf2/Bcl-xL и повышая эффективность сорафениба.

Гепатоклеточная карцинома (ГК) характеризуется плохим прогнозом и остается одной из основных причин смертности от рака во всем мире. Усовершенствованный КЦУК регулируется несколькими методами лечения первой линии, включая ингибиторы тиросина киназы (TKI) и иммунную терапию (mAb-PD-1 и mAb-VEGF). Вместе с тем эффективность лечения КЦХВ зачастую недолговечна. Недавние исследования показали, что активация траектории Nrf2-Bcl-xL способствует плохому прогнозу у группы пациентов с КЦХВ. Здесь мы обнаружили, что диметилфумарат (DMF), лекарство, используемое для лечения псориаза и множественного склер

Gene regulation by non-Coding RNAs in infertility: a mechanistic review.

Infertility is a significant global health issue affecting millions of couples, with noncoding RNAs (ncRNAs) emerging as pivotal regulators in reproductive biology. This review explores the roles of various ncRNAs, including microRNAs (miRNAs), small interfering RNAs (siRNAs), long noncoding RNAs (lncRNAs), PIWI-interacting RNAs (piRNAs), and circular RNAs (circRNAs) in male and female infertility. These ncRNAs modulate critical processes such as spermatogenesis, oogenesis, follicular development, and embryo implantation through mechanisms like post-transcriptional regulation, chromatin remode

Эпштейн-Барр Вирус: больше чем просто инфекция.

Хотя вирус Эпштейн-Барр обычно ассоциируется с доброкачественным инфекционным мононуклеозом, он в настоящее время признается в качестве одного из основных движителей сложных иммунопатологических расстройств. Замыкаясь между литическими репликациями и стратегическими программами запоздалости, EBV перепрограммирует биологию B-клеток, чтобы избежать иммунного наблюдения и нарушить гомеостаз. Центральным элементом этого патогенеза является вирусный протеин EBNA1, который приводит к автоматическому иммунитету с помощью молекулярной имитации с принимающими антигенами, включая GlialCAM в множестве ск

Cyclic Polypeptide D7 Protects Bone Marrow Mesenchymal Cells and Promotes Chondrogenesis during Osteonecrosis of the Femoral Head via Growth Differentiation Factor 15-Mediated Redox Signaling.

Osteonecrosis of the femoral head (ONFH) is a debilitating disease that is closely associated with the clinical application of high-dose glucocorticoids. Elevated oxidative stress contributes to the pathophysiological changes observed in ONFH. The lack of effective treatments besides surgical intervention highlights the importance of finding novel therapeutics. Our previous studies demonstrated that D7, a cyclic polypeptide, enhances the adhesion, expansion, and proliferation of bone marrow mesenchymal stem cells (BMSCs). Therefore, in this study, we investigated the therapeutic effects of D7

Current Advances in RNA Therapeutics for Human Diseases.

Following the discovery of nucleic acids by Friedrich Miescher in 1868, DNA and RNA were recognized as the genetic code containing the necessary information for proper cell functioning. In the years following these discoveries, vast knowledge of the seemingly endless roles of RNA have become better understood. Additionally, many new types of RNAs were discovered that seemed to have no coding properties (non-coding RNAs), such as microRNAs (miRNAs). The discovery of these new RNAs created a new avenue for treating various human diseases. However, RNA is relatively unstable and is degraded fairl

Spectrum of sublytic astrocytopathy in neuromyelitis optica.

Neuromyelitis optica is an autoimmune inflammatory disorder targeting aquaporin-4 water channels in CNS astrocytes. Histopathological descriptions of astrocytic lesions reported in neuromyelitis optica so far have emphasized a characteristic loss of aquaporin-4, with deposition of IgG and complement and lysis of astrocytes, but sublytic reactions have been underappreciated. We performed a multi-modality study of 23 neuromyelitis optica autopsy cases (clinically and/or pathologically confirmed; 337 tissue blocks). By evaluating astrocytic morphology, immunohistochemistry and AQP4 RNA transcript

The Impact of Histone Modifications in Endometriosis Highlights New Therapeutic Opportunities.

Endometriosis is a chronic disorder of the female reproductive system which afflicts a great number of women worldwide. Histone deacetylases (HDACs) prevent the relaxation of chromatin, thereby positively or negatively modulating gene transcription. The current review aims at studying the impact of histone modifications and their therapeutic targeting in endometriosis. In order to identify relevant studies, a literature review was conducted using the MEDLINE and LIVIVO databases. The current manuscript represents the most comprehensive, up-to-date review of the literature focusing on the parti

Clinico-biological significance of suppressor of cytokine signaling 1 expression in acute myeloid leukemia.

Suppressor of cytokine signaling 1 (SOCS1) protein, which encodes a member of signal transducers and activators of transcription-induced inhibitors, takes part in a negative regulation of cytokine signaling. The mechanism of SOCS1 in tumor carcinogenesis is complex and there have been no studies concerning the clinic-biologic implication of SOCS1 expression in acute myeloid leukemia (AML). Here, we first identified that higher bone marrow (BM) SOCS1 expression was closely associated with older age, FLT3-ITD, NPM1 and DNMT3A mutations, but negatively correlated with CEBPA mutation in patients w

The roles of lncRNAs and miRNAs in pancreatic cancer: a focus on cancer development and progression and their roles as potential biomarkers.

Pancreatic ductal adenocarcinoma (PDAC) is among the most penetrative malignancies affecting humans, with mounting incidence prevalence worldwide. This cancer is usually not diagnosed in the early stages. There is also no effective therapy against PDAC, and most patients have chemo-resistance. The combination of these factors causes PDAC to have a poor prognosis, and often patients do not live longer than six months. Because of the failure of conventional therapies, the identification of key biomarkers is crucial in the early diagnosis, treatment, and prognosis of pancreatic cancer. 65% of the

Mechanisms inducing low bone density in Duchenne muscular dystrophy in mice and humans.

Patients affected by Duchenne muscular dystrophy (DMD) and dystrophic MDX mice were investigated in this study for their bone phenotype and systemic regulators of bone turnover. Micro-computed tomographic (µCT) and histomorphometric analyses showed reduced bone mass and higher osteoclast and bone resorption parameters in MDX mice compared with wild-type mice, whereas osteoblast parameters and mineral apposition rate were lower. In a panel of circulating pro-osteoclastogenic cytokines evaluated in the MDX sera, interleukin 6 (IL-6) was increased compared with wild-type mice. Likewise, DMD patie

Emerging evidence of the molecular landscape specific for hematogenous metastasis from gastric cancer.

Gastric cancer (GC) is one of the most frequently diagnosed cancers in the world. Most GC patients are diagnosed when the cancer is in an advanced stage, and consequently, some develop metastatic lesions that generally cause cancer-related death. Metastasis establishment is affected by various conditions, such as tumor location, hemodynamics and organotropism. While digestive cancers may share a primary site, certain cases develop hematogenous metastasis with the absence of peritoneal metastasis, and vice versa. Numerous studies have revealed the clinicopathological risk factors for hematogeno

Evaluating the Link between BAFF System Gene Expression and Acute Rejection Development in Kidney Transplantation.

B-cell activating factor (BAFF) system signaling is critical for B-cell homeostasis, effector functions, and tolerance maintenance in transplants, but it has not been studied in kidney transplant recipients (KTRs). The aim was to analyze the changes in BAFF system expression in KTRs with/without acute rejection (AR/NAR). The BAFF system expression was analyzed by qPCR in 40 KTRs. A meta-analysis of BAFF system expression and histological renal damage was identified by the Chronic Allograft Damage Index (CADI) and performed from the GEO database. Proliferation-inducing ligand (APRIL) expression

The long road to recognition: a historical review of amyloidosis from early pathology to disease-modifying therapy.

Within the last several decades, great strides are being made in both the diagnosis and treatment of cardiac amyloidosis, yet the condition itself has been a severely under-recognized cause of heart failure for centuries. For much of medical history, the accumulation of these insoluble fibril deposits was an enigmatic finding, observed primarily post-mortem in patients suffering from chronic inflammatory conditions. This review traces the fascinating evolution of amyloidosis: from its origins as a botanical term mistakenly applied to human pathology, through the serendipitous discoveries of hi

Growth inhibition of head and neck squamous cell carcinoma cells by sgRNA targeting the cyclin D1 mRNA based on TRUE gene silencing.

Head and neck squamous cell carcinoma (HNSCC) exhibits increased expression of cyclin D1 (CCND1). Previous studies have shown a correlation between poor prognosis of HNSCC and cyclin D1 overexpression. tRNase ZL-utilizing efficacious gene silencing (TRUE gene silencing) is one of the RNA-mediated gene expression control technologies that have therapeutic potential. This technology is based on a unique enzymatic property of mammalian tRNase ZL, which is that it can cleave any target RNA at any desired site by recognizing a pre-tRNA-like complex formed between the target RNA and an artificial sm
