Unleashing the potential of Genistein and its derivatives as effective therapeutic agents for breast cancer treatment

Breast cancer remains one of the leading causes of cancer-related deaths among women worldwide. Genistein (Gen), a phytoestrogen soy isoflavone, has emerged as a promising agent in the prevention and treatment of breast cancer due to its ability to function as a natural selective estrogen receptor modulator (SERM). This review explores the multifaceted mechanisms through which Gen and its derivatives exert their anticancer effects, including modulation of the PI3K/Akt signaling pathway, regulation of apoptosis, inhibition of angiogenesis, and impacts on DNA methylation and enzyme functions. We discuss the dual roles of Gen in both enhancing and inhibiting estrogen receptor (ER)-dependent pathways., highlighting its complex interactions with ERα and ERβ. Furthermore, the review examines the synergistic effect of combining Gen with conventional chemotherapeutic agents such as doxorubicin, cisplatin, and selenium, as well as other natural compounds like lycopene. Clinical studies suggest that while isoflavones may not significantly influence breast cancer progression in general, the high consumption of soy isoflavones is associated with reduced recurrence rates in breast cancer survivors. Importantly, Gen's ability to modulate key signaling pathways and enhance the efficacy of existing treatments improves its potential as a valuable adjunct in breast cancer therapy. In conclusion, Gen and its derivatives offer a novel and promising approach for treatment of breast cancer. Continued research into their mechanisms of action and clinical applications will be essential in optimizing their therapeutic potential and translating these findings into effective clinical interventions.

Disturbing cytoskeleton by engineered nanomaterials for enhanced cancer therapeutics

Cytoskeleton plays a significant role in the shape change, migration, movement, adhesion, cytokinesis, and phagocytosis of tumor cells. In clinical practice, some anti-cancer drugs achieve cytoskeletal therapeutic effects by acting on different cytoskeletal protein components. However, in the absence of cell-specific targeting, unnecessary cytoskeletal recombination in organisms would be disastrous, which would also bring about severe side effects during anticancer process. Nanomedicine have been proven to be superior to some small molecule drugs in cancer treatment due to better stability and targeting, and lower side effects. Therefore, this review summarized the recent developments of various nanomaterials disturbing cytoskeleton for enhanced cancer therapeutics, including carbon, noble metals, metal oxides, black phosphorus, calcium, silicon, polymers, peptides, and metal-organic frameworks, etc. A comprehensive analysis of the characteristics of cytoskeleton therapy as well as the future prospects and challenges towards clinical application were also discussed. We aim to drive on this emerging topic through refreshing perspectives based on our own work and what we have also learnt from others. This review will help researchers quickly understand relevant cytoskeletal therapeutic information to further advance the development of cancer nanomedicine.
