It is believed that lot of ageing-related diseases such as cancers and seemingly contradictory events like cell death in degenerative diseases and uncontrolled cell growth in cancers actually share similar etiology: autophagy defect. Autophagy is one of the most important cellular processes for selective degradation of misfolded/aggregated proteins and dysfunctional organelles. Autophagy defect leads to genome instability that is the origin of most of cancers. However, genome instability has to be amplified through continuous cell division in order to develop into cancers. Currently, the lab is investigating how microtubule/mitochondria-associated protein LRPPRC, MAP1S (C19ORF5) and RASSF1 regulate autophagy, why autophagy defect leads to tumorigenesis, and whether early intervention with chemical components such as nontoxic phytochemicals can reduce the generation and terminate the amplification of genome instability so that tumor initiation is suppressed or progress of tumor development is delayed. Hepatocellular carcinoma is specifically selected as a prototype to study the mechanisms of tumorigenesis in general. The experimental approach will use genetically engineered mice and cultured mammalian cells as models for biochemical, cell biological and cancer biological studies.  Publications/Creative Works Click here to search for this faculty member's publications on PubMed.  Affiliations  Research Consortia Gulf Coast Cluster for Single Cell Omics  Appointments Title Department / School Institution Assistant Professor Center for Translational Cancer Research Institute of Biosciences and Technology -TAMHSC
