Connexin 30 (Cx30), a tumour-suppressive gap junctional protein, impacts on insulin-like growth factor receptor 1-mediated progression and stemness of glioma. Of late, metabolic reprogramming, a recently adjudged hall mark of malignancy, could reasonably associated with the changes in gap junctional communication in glioma. This newly recognized hallmark of reprogramming of metabolism to maintain the rapid proliferation necessitates further probing to establish the stronger hall marks. Hence, the current study attempted to link the association between the expression of Cx30 with glucose uptake and glucose metabolism in glioma. We have transfected Cx30 in C6 glioma cells, characterized by a low level of intercellular communication and developed xenografts to study the status of glucose transporters (GLUTs), hexokinase 2 and Pyruvate dehydrogenase kinase 1 (PDK 1) along with human glioma tissues by RT-PCR and immunoblotting. The results showed a significant increase in the levels of GLUTs, hexokinase 2 and PDK 1 in C6-implanted rat xenografts and high grades compared to their respective controls, whereas Cx30-transfected C6-implanted rat xenograft and low grades show no significant change compared to that of controls supporting the association between Gap junctional communications and glucose metabolism. We strongly speculate the impact of Cx30 over the glucose metabolism that might provide therapeutic prospects and challenges for anti-glycolytic cancer therapy.
