Natural biomolecules and derivatives as anticancer immunomodulatory agents.

Despite advancements in chemotherapy, the issue of resistance and non-responsiveness to many chemotherapeutic drugs that are currently in clinical use still remains. Recently, cancer immunotherapy has gathered attention as a novel treatment against select cancers. Immunomodulation is also emerging as an effective strategy to improve efficacy. Natural phytochemicals, with known anticancer properties, been reported to mediate their effects by modulating both traditional cancer pathways and immunity. The mechanism of phytochemical mediated-immunomodulatory activity may be attributed to the remode

Amyloidosis in Childhood: A Review of Clinical Features and Comparison with Adult Forms.

Amyloidosis is a rare multisystem disorder characterized by extracellular accumulation of insoluble fibrils in various organs and tissues. The most common subtype in the pediatric population is systemic reactive amyloidosis, typically developing secondary to chronic inflammatory conditions and resulting in deposition of serum amyloid A protein in association with apolipoprotein HDL3. Clinical presentation is highly variable and is mostly influenced by specific organs involved, precursor protein type, and extent of amyloid deposition, often closely reflecting clinical features of the underlying

Nuclear-Cytoplasmic Axis in Cancer: From Protein Mislocalization to Anticancer Drug Resistance.

Nucleocytoplasmic transport (NCT) regulates the spatial distribution of proteins and RNA between the nucleus and cytoplasm. NCT dysregulation can mislocalize tumor suppressors, DNA-repair factors, transcription factors, and drug targets in cancer. In this review, we conceptualize NCT-dependent protein mislocalization as a spatial regulatory framework for anticancer drug resistance, rather than as a catalogue of transport components. We systematically discuss how nuclear pore complex (NPC) remodeling, transport-receptor imbalance, post-translational modification (PTM)-regulated cargo routing, s

Emerging new therapeutic antibody derivatives for cancer treatment.

Monoclonal antibodies constitute a promising class of targeted anticancer agents that enhance natural immune system functions to suppress cancer cell activity and eliminate cancer cells. The successful application of IgG monoclonal antibodies has inspired the development of various types of therapeutic antibodies, such as antibody fragments, bispecific antibodies, and antibody derivatives (e.g., antibody-drug conjugates and immunocytokines). The miniaturization and multifunctionalization of antibodies are flexible and viable strategies for diagnosing or treating malignant tumors in a complex t

Why Is Wnt/β-Catenin Not Yet Targeted in Routine Cancer Care?

Despite significant progress in cancer prevention, screening, and treatment, the still limited number of therapeutic options is an obstacle towards increasing the cancer cure rate. In recent years, many efforts were put forth to develop therapeutics that selectively target different components of the oncogenic Wnt/β-catenin signaling pathway. These include small molecule inhibitors, antibodies, and more recently, gene-based approaches. Although some of them showed promising outcomes in clinical trials, the Wnt/β-catenin pathway is still not targeted in routine clinical practice for cancer mana

Postoperative Natural Killer Cell Dysfunction: The Prime Suspect in the Case of Metastasis Following Curative Cancer Surgery.

Surgical resection is the foundation for the curative treatment of solid tumors. However, metastatic recurrence due to the difficulty in eradicating micrometastases remain a feared outcome. Paradoxically, despite the beneficial effects of surgical removal of the primary tumor, the physiological stress resulting from surgical trauma serves to promote cancer recurrence and metastasis. The postoperative environment suppresses critical anti-tumor immune effector cells, including Natural Killer (NK) cells. The literature suggests that NK cells are critical mediators in the formation of metastases i

Recent Perspectives on Cardiovascular Toxicity Associated with Colorectal Cancer Drug Therapy.

Cardiotoxicity is a well-known adverse effect of cancer-related therapy that has a significant influence on patient outcomes and quality of life. The use of antineoplastic drugs to treat colorectal cancers (CRCs) is associated with a number of undesirable side effects including cardiac complications. For both sexes, CRC ranks second and accounts for four out of every ten cancer deaths. According to the reports, almost 39% of patients with colorectal cancer who underwent first-line chemotherapy suffered cardiovascular impairment. Although 5-fluorouracil is still the backbone of chemotherapy reg

Salmonella enterica and outer membrane vesicles are current and future options for cancer treatment.

Conventional cancer therapies have many limitations. In the last decade, it has been suggested that bacteria-mediated immunotherapy may circumvent the restrictions of traditional treatments. For example, Salmonella enterica is the most promising bacteria for treating cancer due to its intrinsic abilities, such as killing tumor cells, targeting, penetrating, and proliferating into the tumor. S. enterica has been genetically modified to ensure safety and increase its intrinsic antitumor efficacy. This bacterium has been used as a vector for delivering anticancer agents and as a combination thera

Nephrotoxicity of recent anti-cancer agents.

Cancer patients may develop a variety of kidney lesions that impair not only their immediate survival but also limit the adequate treatment of the underlying malignant process. This review summarizes the nephrotoxic potential of some of the most recently developed anti-cancer drugs, focusing on those interfering with the vascular endothelial growth factor and epidermal growth factor receptor pathways and mammalian target of rapamycin inhibitors. Thrombotic microangiopathy (haemolytic-uraemic syndrome), proteinuria, hypertension and magnesium depletion are the most common side effects. Also the

In this review, we provided an in-depth analysis of the relationships and distinctions between uncontrolled inflammation, fibrosis and cancers, while emphasizing the challenges and opportunities of developing novel therapies for the treatment and/or management of these diseases. We described how drug delivery systems, combination therapy and the integration of tissue-targeted and/or pathways selective strategies could overcome the challenges of current agents for managing and/or treating chroni

Post-transplant cyclophosphamide-induced cardiotoxicity: A comprehensive review.

Cyclophosphamide-induced cardiotoxicity, associated with its toxic metabolite acrolein, is a significant concern and unresolved issue, especially when cyclophosphamide is administrated in high doses. However, cardiotoxicity following low-dose cyclophosphamide has been also documented, especially in post-hematopoietic stem cell transplantation (post-HSCT) settings. Despite the involvement of multiple signaling pathways in cyclophosphamide-induced cardiomyopathy, the exact underlying mechanisms remain to be fully elucidated. This review outlines the current challenges of cyclophosphamide therapy

Short-chain fatty acids in the tumor microenvironment: from molecular mechanisms to cancer therapy.

Short-chain fatty acids (SCFAs), including acetate, propionate, and butyrate, serve as pivotal metabolites within the tumor microenvironment (TME), playing essential roles in modulating tumor progression. Although the biological functions and mechanisms of SCFAs in the TME show some overlap, each SCFA also exerts some distinct regulatory effects on tumors and TME. Notably, even a single SCFA may exhibit pleiotropic effects across different cancer types or under varying conditions within the same malignancy. Consequently, according to the different metabolic microenvironment of patients, precis

Cardio-cerebral infarction: a narrative review of pathophysiology, treatment challenges, and prognostic implications.

Cardio-cerebral infarction (CCI) is a rare clinical syndrome characterized by the simultaneous or sequential occurrence of acute myocardial infarction (AMI) and acute ischemic stroke (AIS). Despite its complex pathogenesis and more severe prognosis compared to isolated AMI or AIS, no consensus has been established regarding its definition, classification, epidemiology, treatment protocols, or prognostic management. Current research is largely confined to case reports or small case series, and there are no unified diagnostic or treatment guidelines, nor any expert consensus. Consequently, clini

Bone, a Secondary Growth Site of Breast and Prostate Carcinomas: Role of Osteocytes.

Bone is the primarily preferred site for breast and prostate cancer to metastasize. Bone metastases are responsible for most deaths related to breast and prostate cancer. The bone's particular microenvironment makes it conducive for the growth of cancer cells. Studies on bone metastasis have focused on the interaction between cancer cells and the bone microenvironment. Osteocytes, the most common cell type of bone tissue, have received little attention in bone metastasis, although they are master signal sensors, integrators, and skeleton transducers. They play an important role in regulating b

The roles of osteoprotegerin in cancer, far beyond a bone player.

Osteoprotegerin (OPG), also known as tumor necrosis factor receptor superfamily member 11B (TNFRSF11B), is a member of the tumor necrosis factor (TNF) receptor superfamily. Characterized by its ability to bind to receptor activator of nuclear factor kappa B ligand (RANKL), OPG is critically involved in bone remodeling. Emerging evidence implies that OPG is far beyond a bone-specific modulator, and is involved in multiple physiological and pathological processes, such as immunoregulation, vascular function, and fibrosis. Notably, numerous preclinical and clinical studies have been conducted to

Case Report: Acute kidney injury due to minimal dilated obstructive nephropathy in the context of gastric cancer.

Postrenal obstruction is a rare but reversible cause of acute kidney injury (AKI), often underrecognized when hydronephrosis is mild or absent. We present a 55-year-old woman with gastric cancer who developed severe AKI requiring hemodialysis. Initial non-contrast abdominal CT revealed only mild bilateral hydronephrosis without obvious ureteral obstruction. Given these subtle radiologic findings and a history of chemotherapy and NSAID exposure. Initially, a multidisciplinary team attributed the AKI to intrinsic renal causes. Subsequent renal biopsy revealed only minimal glomerular changes, ins

Иммунный код мозга: декодирование антигенной презентации на менингеальном-глимфатичном интерфейсе в неврологических расстройствах.

Классический взгляд на иммунную привилегию центральной нервной системы (СНС) эволюционировал от изоляции к регулируемому перекрестному разговору. Перенос церебральных цереброспинных флюидов и менингетических лимфатических сосудов (mLVs) переносят молекулы, полученные из головного мозга, на эмунизированные пограничные ткани и лимфатические узлы шейки матки, где антигенные клетки (APC) декодируют этот молекулярный дренаж в адаптивный иммунитет. Мы настраиваем эту последовательность как код мозга, в котором личность, время, маршрут и клеточный проводник экспортированных антигенов коллективно дикт
