Histone deacetylase inhibitors (HDACIs) cause oncogene‑transformed mammalian cell death. Our previous study indicated that HDACIs activate forkhead box O1 (FOXO1) and induce autophagy in liver and colon cancer cells. However, whether FOXO1 is involved in HDACI‑mediated oncogene‑transformed mammalian cell death remains unclear. In the present study, H‑ras transformed MCF10A cells were used to investigate the role of FOXO1 in this pathway. Results showed that trichostatin A (TSA), a HDACI, activated apoptosis in MCF10A‑ras cells, but not in MCF10A cells...

Transmembrane and ubiquitin-like domain containing protein 1 (Tmub1), formerly known as hepatocyte odd protein shuttling (HOPS) has been recognized as a ubiquitously expressed shuttling protein that moves between the nucleus and cytoplasm in hepatocytes. Tmub1 is involved in liver regeneration and functions as a bridging protein in tumor cell proliferation. To investigate the transcriptional profile and potential biological processes affected by Tmub1 expression in normal rat hepatocytes, microarray and bioinformatics experiments were used to identify 127 mRNAs differentially expressed between Tmub1‑overexpression, Tmub1‑knockdown and normal BRL‑3A cells (fold‑change ≥2...

The production of reactive oxygen species (ROS) is a common phenomenon in podocyte impairment, which leads to the irreversible progression of chronic kidney diseases, such as diabetic kidney disease (DKD). Previous research has indicated that peroxisome proliferator‑activated receptor γ (PPARγ) coactivator‑1α (PGC‑1α) participates in mitochondrial biogenesis and energy metabolism in certain mitochondria‑enriched cells, including myocardial and skeletal muscle cells. Therefore, we hypothesized that PGC‑1α may be a protective nuclear factor against energy and oxidative stress in DKD...
