Targeted Delivery of Drugs and Genes Using Polymer Nanocarriers for Cancer Therapy.

Cancer is one of the primary causes of worldwide human deaths. Most cancer patients receive chemotherapy and radiotherapy, but these treatments are usually only partially efficacious and lead to a variety of serious side effects. Therefore, it is necessary to develop new therapeutic strategies. The emergence of nanotechnology has had a profound impact on general clinical treatment. The application of nanotechnology has facilitated the development of nano-drug delivery systems (NDDSs) that are highly tumor selective and allow for the slow release of active anticancer drugs. In recent years, veh

Pruritus: an overview. What drives people to scratch an itch?

Pruritus is a common complaint associated with many conditions. It negatively impacts sleep, quality of life, and mortality. Itch is transmitted along both histaminergic and non-histaminergic pathways with a complex interplay between keratinocytes, immune cells and cutaneous neurons. Individuals who present with pruritus should undergo a thorough assessment, especially those over 65 years old, to exclude underlying malignancy. Treatment no longer consists of antihistamines alone. Physicians now have an array of therapies in their armamentarium, to help alleviate this distressing symptom.

Oral mucositis induced by anticancer treatments: physiopathology and treatments.

Oral mucositis is a frequent and devastating side effect of anticancer treatments. It impairs the patient's quality of life and also can be life threatening because severe infections and delayed or incomplete anticancer treatments may result. This problem has been largely overlooked and underestimated in the past. However, recently studies have been performed to precisely identify the epidemiology, cost, consequences, physiopathology, and treatments of oral mucositis. Clinical guidelines have recently been published to help the daily management of this frequent complication. In addition, some

Targeting Tumor Glycans for Cancer Therapy: Successes, Limitations, and Perspectives.

Aberrant glycosylation is a hallmark of cancer and can lead to changes that influence tumor behavior. Glycans can serve as a source of novel clinical biomarker developments, providing a set of specific targets for therapeutic intervention. Different mechanisms of aberrant glycosylation lead to the formation of tumor-associated carbohydrate antigens (TACAs) suitable for selective cancer-targeting therapy. The best characterized TACAs are truncated O-glycans (Tn, TF, and sialyl-Tn antigens), gangliosides (GD2, GD3, GM2, GM3, fucosyl-GM1), globo-serie glycans (Globo-H, SSEA-3, SSEA-4), Lewis anti

Circadian rhythm-guided cellular therapy in hematologic malignancies: mechanisms, clinical evidence, and optimization strategies.

Circadian rhythms are endogenous 24-hour timing systems that coordinate hematopoiesis and immune function through central and peripheral clocks. Increasing evidence indicates that the initiation and progression of hematologic malignancies are frequently accompanied by circadian disruption, which not only contributes to malignant transformation and disease progression but also anti-tumor immunity and variable treatment responses. Cellular therapies, particularly hematopoietic stem cell transplantation (HSCT) and chimeric antigen receptor T-cell therapy (CAR-T), have emerged as transformative mo

In recent years, Marine Natural Products (MNPs) have emerged as a significant source for anticancer drug discovery, as many natural products can offer structural diversity, unique mechanisms of action, and relatively low toxicity. This article provides a systematic review of MNPs with reported anticancer activities from 2020 to 2024. These compounds are classified into seven major categories: terpenoids, alkaloids, sterols, polyketides, peptides and proteins, polysaccharides, and macrolides. For each category, we elaborate on the marine sources, structural identification, in vitro anticancer a

Utilization of redox modulating small molecules that selectively act as pro-oxidants in cancer cells to open a therapeutic window for improving cancer therapy.

There is a rapidly growing body of literature supporting the notion that differential oxidative metabolism in cancer versus normal cells represents a metabolic frailty that can be exploited to open a therapeutic window into cancer therapy. These cancer cell-specific metabolic frailties may be amenable to manipulation with non-toxic small molecule redox active compounds traditionally thought to be antioxidants. In this review we describe the potential mechanisms and clinical applicability in cancer therapy of four small molecule redox active agents: melatonin, vitamin E, selenium, and vitamin C
