Cancer Chemoprevention: A Strategic Approach Using Phytochemicals.

Cancer chemoprevention approaches are aimed at preventing, delaying, or suppressing tumor incidence using synthetic or natural bioactive agents. Mechanistically, chemopreventive agents also aid in mitigating cancer development, either by impeding DNA damage or by blocking the division of premalignant cells with DNA damage. Several pre-clinical studies have substantiated the benefits of using various dietary components as chemopreventives in cancer therapy. The incessant rise in the number of cancer cases globally is an issue of major concern. The excessive toxicity and chemoresistance associat

Molecular classification of gastric cancer: Towards a pathway-driven targeted therapy.

Gastric cancer (GC) is the third leading cause of cancer mortality worldwide. Although surgical resection is a potentially curative approach for localized cases of GC, most cases of GC are diagnosed in an advanced, non-curable stage and the response to traditional chemotherapy is limited. Fortunately, recent advances in our understanding of the molecular mechanisms that mediate GC hold great promise for the development of more effective treatment strategies. In this review, an overview of the morphological classification, current treatment approaches, and molecular alterations that have been 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

Advances in Diet and Physical Activity in Breast Cancer Prevention and Treatment.

There is currently a growing interest in diets and physical activity patterns that may be beneficial in preventing and treating breast cancer (BC). Mounting evidence indicates that indeed, the so-called Mediterranean diet (MedDiet) and regular physical activity likely both help reduce the risk of developing BC. For those who have already received a BC diagnosis, these interventions may decrease the risk of tumor recurrence after treatment and improve quality of life. Studies also show the potential of other dietary interventions, including fasting or modified fasting, calorie restriction, keto

Cancer stem cells: advances in knowledge and implications for cancer therapy.

Cancer stem cells (CSCs), a small subset of cells in tumors that are characterized by self-renewal and continuous proliferation, lead to tumorigenesis, metastasis, and maintain tumor heterogeneity. Cancer continues to be a significant global disease burden. In the past, surgery, radiotherapy, and chemotherapy were the main cancer treatments. The technology of cancer treatments continues to develop and advance, and the emergence of targeted therapy, and immunotherapy provides more options for patients to a certain extent. However, the limitations of efficacy and treatment resistance are still i

Application of dendritic cell extracellular vesicles as a valid nanoparticle platform for cancer therapies: a narrative review.

The prevalence of cancers has actually increased during the last few decades, affecting almost all human societies. Despite progress in therapeutic protocols, cancer is still the main cause of global human mortality. Although the advancement of modern immunotherapeutic approaches can increase the survival rate of cancer patients, new modalities are essential for improved therapeutic outcomes. Extracellular vesicles (EVs) are nanosized particles and are used for cell-free approaches instead of direct whole cell-based administration. It has been thought that EVs can reduce the risks and side eff

Curcumin Rewires the Tumor Metabolic Landscape: Mechanisms and Clinical Prospects.

Metabolic reprogramming is a fundamental hallmark and a key driver of malignant tumors. By reshaping glucose, lipid, and amino acid metabolism, as well as mitochondrial function, it sustains the abnormal proliferation and survival of tumor cells, making it a crucial target for anti-tumor therapy. Curcumin, a natural multi-target compound, exhibits unique advantages in intervening in tumor metabolic reprogramming due to its low toxicity and broad-spectrum regulatory properties. In various tumor models, it can directly modulate the activity of key glycolytic enzymes, such as hexokinase 2, lactat

Immunosenescence, Physical Exercise, and their Implications in Tumor Immunity and Immunotherapy.

Aging is associated with a decline in immune function, termed immunosenescence, which compromises host defences and increases susceptibility to infections and cancer. Physical exercise is widely recognized for its myriad health benefits, including the potential to modulate the immune system. This review explores the bidirectional relationship between immunosenescence and physical exercise, focusing on their interplay in shaping antitumor immunity. We summarize the impact of aging on innate and adaptive immune cells, highlighting alterations that contribute to immunosenescence and cancer develo

Specific epigenetic regulators serve as potential therapeutic targets in idiopathic pulmonary fibrosis.

Idiopathic pulmonary fibrosis (IPF), a disorder observed mostly in older human beings, is characterised by chronic and progressive lung scarring leading to an irreversible decline in lung function. This health condition has a dismal prognosis and the currently available drugs only delay but fail to reverse the progression of lung damage. Consequently, it becomes imperative to discover improved therapeutic compounds and their cellular targets to cure IPF. In this regard, a number of recent studies have targeted the epigenetic regulation by histone deacetylases (HDACs) to develop and categorise

New landscapes and horizons in hepatocellular carcinoma therapy.

Hepatocellular carcinoma (HCC), is the sixth most frequent form of cancer and leads to the fourth highest number of deaths each year. HCC results from a combination of environmental factors and aging as there are driver mutations at oncogenes which occur during aging. Most of HCCs are diagnosed at advanced stage preventing curative therapies. Treatment in advanced stage is a challenging and pressing problem, and novel and well-tolerated therapies are urgently needed.

Targeting Cellular Senescence in Aging and Age-Related Diseases: Challenges, Considerations, and the Emerging Role of Senolytic and Senomorphic Therapies.

Cellular senescence is characterized by the permanent arrest of cell proliferation and is a response to endogenous and exogenous stress. The continuous accumulation of senescent cells (SnCs) in the body leads to the development of aging and age-related diseases (such as neurodegenerative diseases, cancer, metabolic diseases, cardiovascular diseases, and osteoarthritis). In the face of the growing challenge of aging and age-related diseases, several compounds have received widespread attention for their potential to target SnCs. As a result, senolytics (compounds that selectively eliminate SnCs
