Beyond boundaries: unraveling innovative approaches to combat bone-metastatic cancers.

Evidence demonstrated that bones, liver, and lungs are the most common metastasis sites in some human malignancies, especially in prostate and breast cancers. Bone is the third most frequent target for spreading tumor cells among these organs and tissues. Patients with bone-metastatic cancers face a grim prognosis characterized by short median survival time. Current treatments have proven insufficient, as they can only inhibit metastasis or tumor progression within the bone tissues rather than providing a curative solution. Gaining a more profound comprehension of the interplay between tumor c

Crosstalk of thioredoxin system and programmed cell death: from pathophysiology to novel therapy.

The thioredoxin (Trx) system, an integral component of cellular redox regulation, preserves protein dithiol-disulfide equilibrium through its conserved Cys-Gly-Pro-Cys active site and is involved in key cellular functions, including cell proliferation, apoptosis, and signal transduction. In cancer biology, the thioredoxin system plays dual roles: overexpression can suppress oxidative stress and promote tumor growth, whereas dysfunction can trigger programmed cell death (PCD). However, a critical area for future research is to delineate how Trx modulates the intricate networks of PCD, and to id

Advancing cancer therapy: Nanomaterial-based encapsulation strategies for enhanced delivery and efficacy of curcumin.

Curcumin, a polyphenolic compound derived from Curcuma longa, has gained significant attention as a potential anticancer agent due to its anti-inflammatory, antioxidant, and antitumor properties. Despite its therapeutic potential, the clinical application of curcumin is limited by its poor aqueous solubility, rapid metabolism, and limited bioavailability. To address these limitations, various nanomaterial-based encapsulation strategies have been developed, including polymeric nanoparticles, liposomes, solid lipid nanoparticles, micelles, dendrimers, and hybrid nanomaterials. These formulations

Navigating the Landscape of Exosomal microRNAs: Charting Their Pivotal Role as Biomarkers in Hematological Malignancies.

Under physiological and pathological conditions, all cells release extracellular vesicles named exosomes, which act as transporters of lipidic, protein, and genetic material from parent to recipient cells. Neoplastic cells can secrete higher number of exosomes to exert pro-tumoral effects such as microenvironmental changes, disease progression, immunosuppression and drug-resistance. This holds true for both organ-specific cancers and hematologic malignancies. One of the most important components of exosomal cargo are microRNAs which can mediate all the abovementioned effects. More specifically

Revolutionizing the treatment for nasopharyngeal cancer: the impact, challenges and strategies of stem cell and genetically engineered cell therapies.

Nasopharyngeal carcinoma (NPC) is a distinct malignancy of the nasopharynx and is consistently associated with the Epstein-Barr virus (EBV) infection. Its unique anatomical location and complex aetiology often result in advanced-stage disease at first diagnosis. While radiotherapy (RT) and chemotherapy have been the mainstays of treatment, they often fail to prevent tumour recurrence and metastasis, leading to high rates of treatment failure and mortality. Recent advancement in cell-based therapies, such as chimeric antigen receptor (CAR)-T cell therapy, have shown great promise in hematologic
