Therapeutic insights into “awakening the sleeping/cancer-protecting angels” in mutant p53-expressing human tumors: Valproic acid, used in the treatment of epilepsy, bipolar disorder and migraine headaches, increases the expression of tumor suppressor p53 homologue TA-p73/p63, PTEN, TPM1, TIMP3, BTG2, PDCD4, SPRY1/2 and CCM1/KRIT1 and induces regression of p53-mutated human tumors via down regulation of its target gene, 27/December/2016, 2.55 pm

From Significance of the study to Public health relevance:

Given that: (1) Cancer suppressor p53 is mutated in more than 50% of human cancers of different tissue origin; (2) p53 pathway is altered in about 80% of tumors.; (3) our understanding is incomplete in terms of molecular targets and the oncogenic/malignant pathways involved in mutant p53-overexpressing tumors; (4) cancer causes the highest economic loss compared to all the known causes of death worldwide; and (5) cancer causes the considerable economic loss worldwide, there is an urgent need to find: (i) a cheaper alternative to the existing expensive drugs; (ii) a side-effect-free natural product-based drug; and (iii) a way to effectively treat and stall metastatic progression and relapse of mutant p53-overexpressing human cancers.


From therapeutic strategy to Research Findings:

(i) Therapeutic strategy: 

This study suggests a therapeutic strategy for stalling the progression of p53-deficient/deleted or mutant-p53 expressing metastatic cancers. By activating tumor suppressor p53’s unmutated “homologous protein such as TAp73/p63” in p53-deficient or mutant-p53 expressing metastatic cancer cells, one can stall their progression.

(ii) Research findings:  

Valproic acid, by decreasing the expression of its target genes, it may not only increase the expression of tumor suppressors genes, such as TAp73, TAp63, PTEN, etc., but also increase a number of metastatic suppressor genes, such as TPM1, TIMP3, BTG2, PDCD4, SPRY1/2, CCM1/KRIT1 etc. Thereby, it may inhibit the migration and invasion of metastatic cancer cells expressing mutant-p53 (figure1).

Figure 1. Mechanistic insight into how Valproic acid functions as an anticancer agent. Valproic acid, by activating tumor suppressor genes, such as TAp73, TAp63, PTEN, PDCD4, BTG2, etc., and metastatic suppressor genes, such as TPM1, TIMP3, SPRY1/2 etc., in  metastatic tumors, it may inhibit the progression of mutant-p53 expressing human cancers.


Therapeutic opportunity:

Given the ability of Valproic acid to induce the expression of TAp73, TAp63, PTEN, TPM1, TIMP3, BTG2, PDCD4, SPRY1/2, CCM1/KRIT1, long ncRNA Gas5 in p53-mutated human tumors, pharmacological formulations encompassing “Valproic acid (VA) or its analogues or  VA plus any of the known anticancer agents” may be used to inhibit the progression of p53-mutated invasive metastatic tumors.
