Application of Nanoparticles for Magnetic Hyperthermia for Cancer Treatment-The Current State of Knowledge.

Hyperthermia (HT) is an anti-cancer therapy commonly used with radio and chemotherapies based on applying heat (39-45 °C) to inhibit tumor growth. However, controlling heat towards tumors and not normal tissues is challenging. Therefore, nanoparticles (NPs) are used in HT to apply heat only to tumor tissues to induce DNA damage and the expression of heat shock proteins, which eventually result in apoptosis. The aim of this review article is to summarize recent advancements in HT with the use of magnetic NPs to locally increase temperature and promote cell death. In addition, the recent develop

Applications of nanotechnologies for miRNA-based cancer therapeutics: current advances and future perspectives.

MicroRNAs (miRNAs) are short (18-25 nt), non-coding, widely conserved RNA molecules responsible for regulating gene expression via sequence-specific post-transcriptional mechanisms. Since the human miRNA transcriptome regulates the expression of a number of tumor suppressors and oncogenes, its dysregulation is associated with the clinical onset of different types of cancer. Despite the fact that numerous therapeutic approaches have been designed in recent years to treat cancer, the complexity of the disease manifested by each patient has prevented the development of a highly effective disease

Microbiota-derived metabolites as modulators of cancer immunotherapy response.

The microbiome is a key regulator of host homeostasis and immune activity, in part through the production of metabolites. These microbiota-derived metabolites can modulate both the innate and adaptive immune system, as well as directly target tumour cells, thereby regulating anti-tumour immunity and response to immunotherapy. Here, we describe the current mechanistic knowledge on how these metabolites exert their effects and outline the methodologies used to detect and assess these metabolites. Finally, we summarize microbiota-targeted therapies capable of improving microbial functionality to

Sialyltransferase Inhibitors for the Treatment of Cancer Metastasis: Current Challenges and Future Perspectives.

Potent, cell-permeable, and subtype-selective sialyltransferase inhibitors represent an attractive family of substances that can potentially be used for the clinical treatment of cancer metastasis. These substances operate by specifically inhibiting sialyltransferase-mediated hypersialylation of cell surface glycoproteins or glycolipids, which then blocks the sialic acid recognition pathway and leads to deterioration of cell motility and invasion. A vast amount of evidence for the in vitro and in vivo effects of sialyltransferase inhibition or knockdown on tumor progression and tumor cell meta

Influence of the Mediterranean Diet on Healthy Aging.

The life expectancy of the global population has increased. Aging is a natural physiological process that poses major challenges in an increasingly long-lived and frail population. Several molecular mechanisms are involved in aging. Likewise, the gut microbiota, which is influenced by environmental factors such as diet, plays a crucial role in the modulation of these mechanisms. The Mediterranean diet, as well as the components present in it, offer some proof of this. Achieving healthy aging should be focused on the promotion of healthy lifestyle habits that reduce the development of pathologi

Mucosal-Associated Invariant T Cells in Health and Disease.

Mucosal-associated invariant T (MAIT) cells are a population of evolutionarily conserved, unconventional innate-like T lymphocytes that are restricted by major histocompatibility complex Class I-related (MR1) molecules. They can be activated either in a T-cell receptor-MR1- or cytokine-dependent manner. Activated MAIT cells play crucial roles in maintaining homeostasis and the fine regulation of the immune system. This review presents a systematic exploration of the development, biological characteristics, and multiple effects of MAIT cells in health and various diseases. In healthy individual
