A sweet way to treat Metastatic cancers: Xylobiose, a disaccharide of xylose, increases the expression of tumor/metastatic suppressors PIAS3 and RhoB, inhibits cell cycle progression, and suppresses migration, invasion and metastasis of cancer cells via up regulation of its target gene, 14/November/2018, 12.24 am

Taming cancers with anti-tapeworm drugs: Niclosamide (brand name: Niclocide, Fenasal, Phenasal), an anti-tapeworm drug,  increases the expression of tumor suppressors genes, such as SMAD7, p12(DOC1/CDK2AP1), p53, TAp63, TAp73, INK4a/ARF, and others, and induces regression of p53-mutated human cancers and other cancers, via up-regulation of its target gene, 14/October/2018, 12.12 am

Probiotic-based therapy for Hepatocellular carcinoma: Probiotic Lactobacillus Rhamnosus attenuates phosphoenolpyruvate carboxykinase (PEPCK1) sumoylation, stabilizes PEPCK1 levels, promotes gluconeogenesis, inhibits glycolysis and attenuates the progression of hepatocellular carcinoma via upregulation of its target gene, 14/December/2018, 12.36 pm

From Significance of the study to Public health relevance: 

Given that: (i) each year nearly 14 million people are diagnosed with cancer globally, and little more than half of them will die; (ii) cancer deaths globally are expected to be doubled by 2030; (iii) most of the cancer patients die due to metastasis; (iv) cancer treatment causes the highest economic loss compared to all the known causes of death worldwide, there is an urgent need to find: (i) bio-molecules that drive metastatic process; and the the way to prevent their expression; (ii) a way to activate immune system to combat cancer (Cancer immunotherapy); (ii) a cheaper alternative to the existing expensive anticancer drugs; (ii) a side-effect-free natural product-based drug; (iii) increase the therapeutic index of anticancer drugs; and (iv) a way to effectively treat and prevent metastatic progression and relapse of advanced/drug-resistant cancers.


Research findings to Therapeutic opportunity: 

This study suggests, for the first time, that  Xylobiose, by regulating the expression of its target genes, it may increase the expression of tumor/metastatic suppressors  PIAS3 and RhoB (fig. 1).

Thereby, it may: (a) inhibit cell cycle progression; and (b) suppress migration, invasion and metastasis of cancer cells.   [easy_payment currency=”USD”]

Given the mechanism of action of Xylobiose and its non-toxic nature compared to other anticancer drugs , it may be an ideal anti-metastatic agent to  (i) increase the expression of metastasis suppressor genes in tumors; (ii) inhibit the progression of metastatic tumors; and (ii) enhance the efficacy of Cancer therapy.

Taken together, this study suggests that oncologists may consider treating terminally ill metastatic cancer patients with Xylobioseto stall the progression of advanced metastatic cancers.
