Background:
Fueled by rapidly evolving comprehension of multifaceted nature of cancers, recently emerging preclinical and clinical data have supported researchers in the resolution of knowledge gaps to deepen the understanding of the molecular mechanisms. The extra-ordinary and bewildering chemical diversity encompassed by biologically active natural products continues to be of relevance to drug discovery. Accumulating evidence has spurred a remarkable evolution of concepts related to pharmacological target of oncogenic signaling pathways by polysaccharides in different cancers.
Purpose:
The objective of the current review is to provide new insights into study progress on anticancer effects of bioactive herbal polysaccharides.
Methods:
PubMed, Scopus, Web of Science, Embase, and other databases were searched for articles related to anticancer effects of polysaccharides. Searches were conducted to locate relevant publications published up to October 2022.
Results:
Polysaccharides have been reported to pleiotropically modulate TGF/SMAD, BMP/SMAD, TLR4, mTOR, CXCR4 and VEGF/VEGFR cascades. We have also summarized how different polysaccharides regulated apoptosis and non-coding RNAs. Additionally, this mini-review describes increasingly sophisticated understanding related to polysaccharides mediated tumor suppressive and anti-metastatic effects in tumor-bearing mice. We have also provided an overview of the clinical trials related to chemopreventive role of polysaccharides.
Conclusion:
Genomic and proteomic findings from these studies will facilitate 'next-generation' clinical initiatives in the prevention/inhibition of cancer.

However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...

When the tumor suppressor genes develop mutations or are lost, cells start growing out of control, leading to cancer. However, a single functional copy of the tumor suppressor gene is enough for the cells to maintain their normal functions and cell...
