Advancement of NF-κB Signaling Pathway: A Novel Target in Pancreatic Cancer.

Pancreatic ductal adenocarcinoma (PDAC) is one of the deadliest cancers and is the third highest among cancer related deaths. Despite modest success with therapy such as gemcitabine, pancreatic cancer incidence remains virtually unchanged in the past 25 years. Among the several driver mutations for PDAC, Kras mutation contributes a central role for its development, progression and therapeutic resistance. In addition, inflammation is implicated in the development of most human cancer, including pancreatic cancer. Nuclear factor kappa-light-chain-enhancer of activated B cells (NF-κB) is recogniz

The Roadmap of RANKL/RANK Pathway in Cancer.

The receptor activator of the nuclear factor-κB ligand (RANKL)/RANK signaling pathway was identified in the late 1990s and is the key mediator of bone remodeling. Targeting RANKL with the antibody denosumab is part of the standard of care for bone loss diseases, including bone metastases (BM). Over the last decade, evidence has implicated RANKL/RANK pathway in hormone and HER2-driven breast carcinogenesis and in the acquisition of molecular and phenotypic traits associated with breast cancer (BCa) aggressiveness and poor prognosis. This marked a new era in the research of the therapeutic use o

Prognostic utility of macrophage polarization (CD68/CD163 ratio) in Egyptian JAK2 positive myeloproliferative neoplasm patients: a single center study.

BackgroundMyeloproliferative neoplasms (MPNs) are clonal hematopoietic disorders with variable clinical outcomes influenced by the bone marrow microenvironment. Tumor-associated macrophages (TAMs), particularly the M1 (CD68⁺) and M2 (CD163⁺) subtypes, play critical roles in inflammation, fibrosis, and immune modulation. This study evaluates CD68- and CD163-positive macrophage frequencies across MPN subtypes and their clinical/prognostic significance.MethodsIn this retrospective cohort study, 121 patients with histopathologically confirmed BCR::ABL1-negative, JAK2V617F-positive MPNs were assess

Challenge of cancer in the elderly.

Despite the sustained trend of decreasing overall cancer incidence, the number of elderly patients with cancer will considerably increase in the coming years, as the incidence of cancer is elevated 11-fold after the age of 65 years compared to adults up to 65 years. This soon-to-erupt tsunami of elderly patients with cancer requires adequate treatment, for which guidelines and evidence-based data are still scarce, given the longlasting under-representation of elderly patients with cancer in cancer trials. Older adults present not only with the physiological decreases of organ functions related

Clinical innovations and future directions of nanoparticles in the treatment of psychiatric and neurological disorders.

Nanoparticles (NPs) provide a versatile toolkit for psychiatry and neurology by leveraging tunable size, surface chemistry, and payload control to overcome long-standing barriers in central nervous system (CNS) therapy. Lipid, polymeric, inorganic, and hybrid NPs can be engineered to traverse the blood-brain barrier (BBB) via receptor/transporter pathways, target specific cell types, and deliver sustained or stimuli-responsive release. Beyond drug delivery, NPs improve imaging, enable gene/RNA therapeutics, and support anti-inflammatory and neuroprotective strategies, advancing precision medic

Novel roles of PIWI proteins and PIWI-interacting RNAs in human health and diseases.

Non-coding RNA has aroused great research interest recently, they play a wide range of biological functions, such as regulating cell cycle, cell proliferation, and intracellular substance metabolism. Piwi-interacting RNAs (piRNAs) are emerging small non-coding RNAs that are 24-31 nucleotides in length. Previous studies on piRNAs were mainly limited to evaluating the binding to the PIWI protein family to play the biological role. However, recent studies have shed more lights on piRNA functions; aberrant piRNAs play unique roles in many human diseases, including diverse lethal cancers. Therefore

Novel immunotherapeutic approaches in gastric cancer.

Gastric cancer is a malignant tumor that ranks third in cancer-related deaths worldwide. Early-stage gastric cancer can often be effectively managed through surgical resection. However, the majority of cases are diagnosed in advanced stages, where outcomes with conventional radiotherapy and chemotherapy remain unsatisfactory. Immunotherapy offers a novel approach to treating molecularly heterogeneous gastric cancer by modifying the immunosuppressive tumor microenvironment. Immune checkpoint inhibitors and adoptive cell therapy are regarded as promising modalities in cancer immunotherapy. Food

Neuroinflammatory Process Involved in Different Preclinical Models of Chemotherapy-Induced Peripheral Neuropathy.

Peripheral neuropathies are characterized by nerves damage and axonal loss, and they could be classified in hereditary or acquired forms. Acquired peripheral neuropathies are associated with several causes, including toxic agent exposure, among which the antineoplastic compounds are responsible for the so called Chemotherapy-Induced Peripheral Neuropathy (CIPN). Several clinical features are related to the use of anticancer drugs which exert their action by affecting different mechanisms and structures of the peripheral nervous system: the axons (axonopathy) or the dorsal root ganglia (DRG) ne

Lymph node metastasis in cancer progression: molecular mechanisms, clinical significance and therapeutic interventions.

Lymph nodes (LNs) are important hubs for metastatic cell arrest and growth, immune modulation, and secondary dissemination to distant sites through a series of mechanisms, and it has been proved that lymph node metastasis (LNM) is an essential prognostic indicator in many different types of cancer. Therefore, it is important for oncologists to understand the mechanisms of tumor cells to metastasize to LNs, as well as how LNM affects the prognosis and therapy of patients with cancer in order to provide patients with accurate disease assessment and effective treatment strategies. In recent years

Recent progress on the effects of microRNAs and natural products on tumor epithelial-mesenchymal transition.

Epithelial-mesenchymal transition (EMT) is a biological process of phenotypic transition of epithelial cells that can promote physiological development as well as tissue healing and repair. In recent years, cancer researchers have noted that EMT is closely related to the occurrence and development of tumors. When tumor cells undergo EMT, they can develop enhanced migration and local tissue invasion abilities, which can lead to metastatic growth. Nevertheless, two researches in NATURE deny its necessity in specific tumors and that is discussed in this review. The degree of EMT and the detection

Endometriosis has high latency and diagnostic methods are both limited and invasive.Aim of reviewThe aim of this review is to summarise minimally invasive or non-invasive diagnostic methods for endometriosis and their diagnostic efficiencies. Furthermore, we discuss the identification and diagnostic potential of novel disease biomarkers of microb

Ligand-Gated Ion Channels as Targets for Treatment and Management of Cancers.

Ligand-gated ion channels are an ionotropic receptor subtype characterized by the binding of an extracellular ligand, followed by the transient passage of ions through a transmembrane pore. Ligand-gated ion channels are commonly subcategorized into three superfamilies: purinoreceptors, glutamate receptors, and Cys-loop receptors. This classification is based on the differing topographical morphology of the receptors, which in turn confers functional differences. Ligand-gated ion channels have a diverse spatial and temporal expression which implicate them in key cellular processes. Given that t

Advances in the mechanism and therapies of achondroplasia.

Achondroplasia (ACH), is the prevailing type of genetic dwarfism in humans, caused by mutations in fibroblast growth factor receptor 3 (FGFR3) that are inherited in an autosomal dominant manner. FGFR3 is mainly expressed in condensed mesenchyme, chondrocytes, and mature osteoblasts and osteoclasts, in which it regulates the formation, development, growth, and remodeling of the skeletal system. Mutations in FGFR3 causing ACH result in enhanced FGFR3 signaling through combined mechanisms including enhancing FGF dimerization and tyrosine kinase activity and stabilizing FGF receptors. In ACH, supp

Myokines in cancer: bridging molecular mechanisms to biomarker discovery and therapeutic innovation.

Exercise can regulate the physiological functions of the body by inducing the secretion of myokines, which are bioactive factors mainly secreted by muscle cells. This review classifies myokines based on their functional characteristics, including metabolic regulation (such as myostatin, interleukin-6), neuroregulation (brain-derived neurotrophic factor), cell proliferation/differentiation regulation (myogenic proteins), immune regulation (tumor necrosis factor- alpha), and factors involved in angiogenesis and extracellular matrix remodeling (such as connective tissue growth factor).Cancer, as

Unexpected massive bleeding caused by extensive maxillary osteonecrosis in a breast cancer patient: a case report.

Diphosphonate application is routinely recommended to treat bone metastasis (BM) in cancer patients. However, the severe side effects of diphosphonate, especially after long-term use, are often overlooked by clinicians. In this article, we describe a case in which a heavily-treated breast cancer patient, suffered from massive bleeding as a result of maxillary osteonecrosis by zoledronic acid (ZA) and apatinib. In October 2018, a 48-year-old Chinese female with breast cancer presented at our department with brain metastases. The patient had experienced progression multiple times and had receive

Exosomes for angiogenesis induction in ischemic disorders.

Ischaemic disorders are leading causes of morbidity and mortality worldwide. While the current therapeutic approaches have improved life expectancy and quality of life, they are unable to "cure" ischemic diseases and instate regeneration of damaged tissues. Exosomes are a class of extracellular vesicles with an average size of 100-150 nm, secreted by many cell types and considered a potent factor of cells for paracrine effects. Since exosomes contain multiple bioactive components such as growth factors, molecular intermediates of different intracellular pathways, microRNAs and nucleic acids, t
