ABSTRACT

Breast cancer (BC) is the most prevalent malignancy in women and the second most common disease worldwide, affecting approximately one million individuals annually. Despite the efficacy of conventional chemotherapy, medication resistance and adverse effects limit its effectiveness, leading researchers to explore alternative treatments, including herbal remedies. Saffron, a well-known spice derived from the Crocus sativus L. plant, has shown potential as a BC treatment. The active components of saffron exhibit anti-cancer properties by inducing apoptosis, inhibiting cell division, and modulating signaling pathways implicated in cancer development, such as PI3K/AKT, NF-κB, and MAPK. Clinical findings suggest that saffron can alleviate chemotherapy-induced symptoms, reduce serum tumor marker levels, and enhance quality of life. Preliminary clinical trials are investigating the safety and efficacy of saffron in treating BC, with recent evidence indicating that recommended doses of saffron supplementation are well-tolerated and safe. This review provides an overview of the anti-tumor effects of saffron and its unique chemical composition in BC. However, further research and clinical studies are imperative to fully comprehend the potential of saffron in adjuvant therapy for BC patients.

ABSTRACT

PURPOSE: T-cell immunoglobulin and ITIM domain (TIGIT) is an immune checkpoint that is overexpressed on both immune cells and some cancer cells. TIGIT can alter the anti-tumor responses inside the tumor microenvironment. Hypoxia-inducible factor 1-alpha (HIF-1α) plays a significant role in the TME and involves suppressing the anti-tumor responses. Under hypoxic conditions, HIF-1α can enhance the expression of different immune checkpoints. Accordingly, hypoxic TME and TIGIT overexpression cause cancer development. Thus, we decided to inhibit tumor cell expansion by inhibiting TIGIT and HIF-1α molecules and discovering the relationship between TIGIT and HIF-1α. METHODS: In this research, we utilized superparamagnetic iron oxide-based NPs (SPIONs) combined with chitosan lactate (CL) and folic acid (FA) nanoparticles (NPs) loaded with TIGIT-siRNA and HIF-1α- siRNA for suppressing TIGIT and HIF-1α in tumor cells and evaluated the consequences of this treatment strategy on tumor growth, apoptosis, and metastasis. RESULTS: The results showed that cancer cells treated with TIGIT and HIF-1α siRNA-loaded SPIONs-CL-FA NPs, strongly suppressed the TIGIT and HIF-1α expression, colony formation ability, angiogenesis, and the growth rate of cancer cells. CONCLUSIONS: Present data suggest the combination treatment of TIGIT and HIF-1α as a novel treatment strategy against colorectal and breast cancer, but more researches are required to realize the complete role of TIGIT and HIF-1α inside the TME.

ABSTRACT

OBJECTIVE: Gastric cancer is a multifactorial disease. In addition to environmental factors, many genes are involved in this malignancy. One of the genes associated with gastric cancer is CD44 gene and its polymorphisms. CD44 gene plays role in regulating cell survival, growth and mobility. The single nucleotide polymorphism (SNP) rs8193, located in the CD44 gene, has not been studied in gastric cancer patients of the Iranian population. The present study aims to study this polymorphism in 86 gastric cancer patients and 96 healthy individuals. MATERIALS AND METHODS: In this cross-sectional case-control study, rs8193 polymorphism was genotyped by allele specific primer polymerase chain reaction (ASP-PCR) technique. The obtained data were statistically analyzed. To find the potential mechanism of action, rs8193 was bioinformatically investigated. RESULTS: rs8193 C allele played a risk factor role for gastric cancer. Patients carrying this allele were more susceptible to have gastric cancer, with lymph node spread. On the other hand, rs8193 T allele, a protective factor, was associated with a higher chance of accumulation in the lower stages of cancer. C allele might impose its effect via destabilizing CD44 and miR-570 interaction. CONCLUSION: rs8193 is statistically associated with the risk of malignancy, lymph node spread and stage of gastric cancer in Iranian population.

ABSTRACT

Breast cancer is the most common type of cancer among women. Therefore, discovery of new and effective drugs with fewer side effects is necessary to treat it. Sulforaphane (SFN) is an organosulfur compound obtained from cruciferous plants, such as broccoli and mustard, and it has the potential to treat breast cancer. Hence, it is vital to find out how SFN targets certain genes and cellular pathways in treating breast cancer. In this review, molecular targets and cellular pathways of SFN are described. Studies have shown SFN inhibits cell proliferation, causes apoptosis, stops cell cycle and has anti-oxidant activities. Increasing reactive oxygen species (ROS) produces oxidative stress, activates inflammatory transcription factors, and these result in inflammation leading to cancer. Increasing anti-oxidant potential of cells and discovering new targets to reduce ROS creation reduces oxidative stress and it eventually reduces cancer risks. In short, SFN effectively affects histone deacetylases involved in chromatin remodeling, gene expression, and Nrf2 anti-oxidant signaling. This review points to the potential of SFN to treat breast cancer as well as the importance of other new cruciferous compounds, derived from and isolated from mustard, to target Keap1 and Akt, two key regulators of cellular homeostasis.
