Introduction:What they say:

A recent study from Department of Molecular and Cellular Oncology, The University of Texas MD Anderson Cancer Center, Unit 108, 1515 Holcombe Boulevard, Houston, TX 77030, USA shows that “Deubiquitination and Stabilization of PD-L1 by CSN5.” This study was published in the 12 December 2016 issue of Cancer cell (one of the best journals in Cancer Science with an impact factor of 23.523) by Prof Mien-Chie Hung, Lim SO and others.


What we say

On the foundation of this interesting finding, Dr L Boominathan PhD, Director-cum-chief Scientist of GBMD, reports that: Small molecule-based PD-L1 pathway blockade enhances the efficacy of Cancer immunotherapy: BMP4 (Bone Morphogenetic Protein-4) inhibits the expression of PD-L1, inhibits inflammatory signalling and the number of tumor-infiltrating lymphocytes and macrophages, increases Cytotoxic activity of T-cells, decreases tumor burden and increases survival via up-regulation of its target gene


What is known?

It has recently been shown that blocking cell surface receptor PD-1 with antibodies one could make tumors shrink. This work, relating to Cancer immunotherapy, has been chosen as Science’s breakthrough of the year recently.


From Research Findings to Therapeutic opportunity

BMP4, by increasing the expression of its target gene, it may  ubiquitinate and destabilize PD-L1 (fig. 1). Thereby, it may: (i) diminish PD-L1 expression in cancer cells; (ii) inhibit inflammatory TNFα signaling; (iii) decrease the number of tumor-infiltrating lymphocytes and macrophages; (iv) increase T-cell anti-tumor immunity; (v) decrease tumor burden; and (vi) increase survival of patients with breast cancer (fig. 1).  

BMP4 inhibits PDL1 expression

Figure 1. Mechanistic insight into how BMP4 enhances the efficacy of cancer immunotherapy. BMP4, by decreasing the expression of PD-L1 in cancer cells, it augments T-cell mediated anti-tumor immunity

Thus, pharmacological formulations encompassing “BMP4 activators or BMP4 activators in combination with other drugs may be used to (i) inhibit the progression of tumors; and (ii) enhance the efficacy of Cancer immunotherapy.price-100
