As the results showed, peritumoral injection of liposome-encapsulated miR-26a-5p-inhibitor promoted subcutaneous tumor growth about 50% under treatment of PTX (p < 0.001, Figure 6H), and down-regulation of MTDH increased the PTX-induced tumor growth inhibition about 30% (p < 0.001, Figure 6I). The gene discussed is MTDH; the disease is neoplasm.
