MTDH and retinoblastoma: Previously, MTDH expression was determined in glucose-induced proximal tubular epithelial cells.34 Recent studies have demonstrated that MTDH knockdown leads to the inhibition of cell growth and induces the apoptosis in human retinoblastoma as well as in hepatocellular carcinoma.35, 36 Here we showed that Mtdh is expressed in the tubules as well as the glomeruli, predominantly in podocytes.
