ABSTRACT
Renal fibrosis, especially tubulointerstitial fibrosis, is the most common pathway of all chronic kidney diseases progressing to end-stage renal diseases. Several adaptive reactions occur in renal tubular epithelial cells after chronic injury, such as changes in glycolipid metabolism, unfolded protein response, autophagy and senescence, epithelial-to-mesenchymal transition and G2/M cell cycle arrest. Maladaptive repair mechanisms can induce tubulointerstitial fibrosis. This article will discuss the molecular mechanism of these adaptive responses of renal tubular epithelial cells driving renal tubulointerstitial fibrosis, and provide a basis for exploring new drug targets for renal tubulointerstitial fibrosis.
ABSTRACT
Hepatocellular carcinoma cells interact with tumor microenvironment, and exhibits There are temporal and spatial heterogeneity of hepatocellular carcinoma which interacts with tumor microinvironment. In this paper, we summarized the characteristics of hepatocellular carcinoma heterogeneity, the mechanism of heterogeneity, and the impact of hepatocellular carcinoma heterogeneity on diagnosis and treatment, so as to provide a new thinking direction for the diagnosis and treatment of hepatocellular carcinoma.
