Prompted by published reports that blockade of mTOR pathway is useful to prevent the progression of DN (Swaroop et al., 2024) and encouraged by our own findings that blockade of SLC6A14 by α-MT suppresses mTOR signaling (Karunakaran et al., 2011), we examined the proteins associated with this pathway in the present study. This evidence concerns the gene SLC6A14 and liver dysplastic nodule.
