Mutants in LRPPRC gene was found to be associated with French Canadian Type Leigh syndrome. Here we used a mouse model to confirm that LRPPRC acted through P62 and HDAC6 to activate autophagy and through Yap and P27 to maintain genome stability so that hepatocellular carcinoma was suppressed.
CUL4B is first identified as a mental retardation gene in our laboratory. We further confirmed that CUL4B also functions importantly in cancer. In our latest publication, we revealed CUL4B sustained the oncogenic properties in bladder cancer through regulating miR-372/373-PIK3CA/AKT axis.
Endocrine tumors frequently show PKA activation even in the absence of mutations in relevant genes. Here we used GH-secreting pituitary tumor cells to discover a novel mechanism through which hypoxia and HIF-1α activate PKA by altering the expression of the regulatory RIIB subunit.
C1orf35 is a gene first cloned and identified in our laboratory, but little is known about its function. We confirmed it a candidate oncogene in the current study, and explored how it promote tumorigenesis.
