Wild-type p53-induced phosphatase 1 (Wip1), a phosphatase previously considered as an oncogene, has been implicated in the regulation of thymus homeostasis and neutrophil maturation. However, the role of Wip1 in B-cell development is unknown. We show that Wip1-deficient mice exhibit a significant reduction of B-cell numbers in the bone marrow, peripheral(More)
Beyond its role in recycling intracellular components nonselectively to sustain survival in response to metabolic stresses, autophagy can also selectively degrade specific cargoes such as damaged or dysfunctional organelles to maintain cellular homeostasis. Mitochondria, known as the power plant of cells, are the critical and dynamic organelles playing a(More)
Autophagy is a self-proteolytic process that degrades intracellular material to enable cellular survival under unfavorable conditions. However, how autophagy is activated in human carcinogenesis remains largely unknown. Herein we report an epigenetic regulation of autophagy in human cancer cells. YY1 (YY1 transcription factor) is a well-known epigenetic(More)
UNLABELLED The liver possesses extraordinary regenerative capacity in response to injury. However, liver regeneration (LR) is often impaired in disease conditions. Wild-type p53-induced phosphatase 1 (Wip1) is known as a tumor promoter and enhances cell proliferation, mainly by deactivating antioncogenes. However, in this work, we identified an unexpected(More)
Doxorubicin induces DNA damage to exert its anti-cancer function. Histone deacetylase 1 (HDAC1) can protect the genome from DNA damage. We found that doxorubicin specifically downregulates HDAC1 protein expression and identified HDAC1 as a target of miR-520h, which was upregulated by doxorubicin. Doxorubicin-induced cell death was impaired by exogenous(More)
