Inhibition of MALAT1 facilitates ROS accumulation via the Keap1/HO-1 pathway to enhance photodynamic therapy in secondary hyperparathyroidism.

The prevalence of secondary hyperparathyroidism (SHPT) in advanced chronic kidney disease (CKD) exceeds 80 %. Our previous study indicated that photodynamic therapy (PDT) has potential for treating SHPT. Long noncoding RNA (lncRNA) is involved in various oxidative stress and apoptotic processes, but the molecular mechanism remains unreported. In this study, we found that PDT induced apoptosis in SHPT through reactive oxygen species (ROS) accumulation. The expression of metastasis-associated lung adenocarcinoma transcript 1 (MALAT1) and heme oxygenase 1 (HO-1) within SHPT was upregulated after

Ferroptosis and its emerging role in esophageal cancer.

The occurrence and development of tumors involve a series of life activities of cells, among which cell death has always been a crucial part in the research of tumor mechanisms and treatment methods. Ferroptosis is a non-apoptotic form of cell death, which is characterized by lipid peroxidation accumulation and further cell membrane rupture caused by excessive production of intracellular oxygen free radicals dependent on iron ions. Esophageal cancer is one of the common digestive tract tumors. Patients in the early stage are mainly treated with surgery, and the curative effect is awe-inspiring

Exosomes in oncofertility: emerging roles in chemotherapy-induced reproductive damage and fertility preservation.

ABSTRACT: Oncofertility has emerged as a critical interdisciplinary field addressing the reproductive challenges faced by cancer patients, particularly those undergoing chemotherapy. While chemotherapeutic agents remain indispensable in cancer therapy, their gonadotoxic effects frequently result in diminished ovarian reserve, impaired spermatogenesis, and long-term infertility. Exosomes - small extracellular vesicles enriched with nucleic acids, proteins, and lipids - are increasingly recognized as key mediators of intercellular communication in both pathological and regenerative contexts. Rec

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

Novel insight and perspectives of nanoparticle-mediated gene delivery and immune-modulating therapies for pancreatic cancer.

Current standard-of-care therapies have failed to improve the survival of patients with metastatic pancreatic cancer (PCA). Therefore, exploring novel therapeutic approaches for cancer targeting is of utmost need. During the past few years, many efforts have been made to develop conventional treatment strategies to reduce chemotherapy resistance. However, critical challenges have impeded current cancer management outcomes, and limited clinical responses have been achieved due to unfavorable off-target effects. Advances in nanotechnology-based gene and immune-modulator delivery systems have exc

Chidamide increases the sensitivity of Non-small Cell Lung Cancer to Crizotinib by decreasing c-MET mRNA methylation.

Introduction: Crizotinib is a kinase inhibitor targeting c-MET/ALK/ROS1 used as the first-line chemical for the treatment of non-small cell lung cancer (NSCLC) with ALK mutations. Although c-MET is frequently overexpressed in 35-72% of NSCLC, most NSCLCs are primarily resistant to crizotinib treatment. Method: A set of NSCLC cell lines were used to test the effect of chidamide on the primary crizotinib resistance in vitro and in vivo. Relationships between the synergistic effect of chidamide and c-MET expression and RNA methylation were systemically studied with a battery of molecular biologic

Histone modifications across cancers: mechanisms, therapy and clinical translation.

Cancer continues to be a major cause of death across the globe, and epigenetic dysregulation, including histone modifications, has been recognized as a major hallmark of cancer development, heterogeneity, and drug resistance. This review seeks to offer an overview of histone modifications in cancer, including the more studied histone modifications such as acetylation and methylation, as well as the less explored histone modifications such as phosphorylation, ubiquitination, and glycosylation. It also examines the role of histone modifications in the dysregulation of the three categories of enz

Identification of Potentially Pathogenic Variants Associated with Recurrence in Medication-Related Osteonecrosis of the Jaw (MRONJ) Patients Using Whole-Exome Sequencing.

Background: Bisphosphonates are antiresorptive and antiangiogenic drugs that prevent and treat bone loss and mineralization in women with postmenopausal osteoporosis and cancer patients. Medication-related osteonecrosis of the jaw (MRONJ) is commonly caused by tooth extraction and dental trauma. Although genetic and pathological studies about MRONJ have been conducted, the pathogenesis of MRONJ still remains unclear. Methods: We aimed to identify genetic variants associated with MRONJ, using whole-exome sequencing (WES). Ten MRONJ patients prescribed bisphosphonates were recruited for WES, and

The Emerging Role of Oncolytic Virotherapy in Glioblastoma Management.

Glioblastoma (GBM) is an aggressive and common form of central nervous system primary malignant tumor in adults. GBM accounts for about half of all gliomas. Despite maximal resection, radiotherapy, and temozolomide, median survival is still 12-15 months because of tumor heterogeneity, diffuse infiltration, and therapeutic resistance. Recurrence is nearly universal, underscoring the need for novel therapies. Oncolytic virotherapy demonstrates a promising strategy that combines direct tumor cell lysis with immune activation. Tumor-selective viruses replicate within malignant cells, induce cell d

XPO1: From basic research to clinical treatment (Review).

Exportin 1 (XPO1) is a key nuclear export receptor that mediates the nuclear export of tumor suppressor proteins and growth‑regulatory mRNAs from the nucleus to the cytoplasm. In several types of cancer, XPO1 is overexpressed or hyperactivated, leading to aberrant cytoplasmic sequestration of key tumor suppressors such as p53, p21, p73, FOXO and Rb. This mislocalization abrogates their nuclear transcriptional functions, disrupting cell cycle arrest, apoptosis and DNA repair, thereby promoting uncontrolled proliferation, survival and therapy resistance. Targeting XPO1 with selective inhibitors

From Cellular Stress to Systemic Adaptation: The Circadian Clock and Stress Response at Cellular and Systemic Levels.

The stress response is essential for cellular and organismal survival as it acts as a protective and adaptive mechanism to maintain homeostasis. At the organismal level, physical stressors induce responses in mammals that are mediated primarily by the hypothalamic-pituitary-adrenal (HPA) axis, which regulates glucocorticoid secretion. The HPA axis functions as a circadian-regulated, multi-oscillator system, in which the paraventricular nucleus, the pituitary, and the adrenal gland exhibit intrinsic rhythmicity while remaining coordinated by the output from the suprachiasmatic nucleus. Glucocor

Molecular interactions of miR-338 during tumor progression and metastasis.

BackgroundCancer, as one of the main causes of human deaths, is currently a significant global health challenge. Since the majority of cancer-related deaths are associated with late diagnosis, it is necessary to develop minimally invasive early detection markers to manage and reduce mortality rates. MicroRNAs (miRNAs), as highly conserved non-coding RNAs, target the specific mRNAs which are involved in regulation of various fundamental cellular processes such as cell proliferation, death, and signaling pathways. MiRNAs can also be regulated by long non-coding RNAs (lncRNAs) and circular RNAs (

Nanomedicine for cancer patient-centered care.

Cancer is a leading cause of morbidity and mortality worldwide, and an increase in incidence is estimated in the next future, due to population aging, which requires the development of highly tolerable and low-toxicity cancer treatment strategies. The use of nanotechnology to tailor treatments according to the genetic and immunophenotypic characteristics of a patient's tumor, and to allow its targeted release, can meet this need, improving the efficacy of treatment and minimizing side effects. Nanomedicine-based approach for the diagnosis and treatment of cancer is a rapidly evolving field. Se

Cardiac Amyloidosis Treatment.

Cardiac amyloidosis (CA) is a restrictive cardiomyopathy with a traditionally poor prognosis. Until recently, CA treatment options were limited and consisted predominantly of managing symptoms and disease-related complications. However, the last decade has seen significant advances in disease-modifying therapies, increased awareness of CA, and improved diagnostic methods resulting in earlier diagnoses. In this review, we provide an overview of current and experimental treatments for the predominant types of CA: transthyretin cardiac amyloidosis (ATTR-CA) and immunoglobulin light chain (AL)-med

Progress and challenges in the treatment of cardiac amyloidosis: a review of the literature.

Cardiac amyloidosis is a restrictive cardiomyopathy determined by the accumulation of amyloid, which is represented by misfolded protein fragments in the cardiac extracellular space. The main classification of systemic amyloidosis is determined by the amyloid precursor proteins causing a very heterogeneous disease spectrum, but the main types of amyloidosis involving the heart are light chain (AL) and transthyretin amyloidosis (ATTR). AL, in which the amyloid precursor is represented by misfolded immunoglobulin light chains, can involve almost any system carrying the worst prognosis among amyl
