Dr. Wenliang Li’s research is to study novel molecular mechanisms of cancer metastasis with the goal of identifying new biomarkers and drug targets for the development of better therapeutics for human cancers.
Dr. Li obtained his Ph.D. in Genetics from Case Western Reserve University in 2004. His dissertation work was conducted in Dr. Bryan Williams’ lab at Cleveland Clinic Foundation, where he constructed a large cancer-specific cDNA microarray and used it to identify gene expression patterns that were associated with genetics and prognosis of human Wilms tumors. He then joined Dr. Ed Harlow’s lab at Harvard Medical School for his postdoctoral training, where he provided critical contributions in a series of collaborative studies in identifying kinases controlling survival and proliferation of human normal and tumor cells. In 12/2010, Dr. Li joined the Brown Foundation Institute of Molecular Medicine, UTHSC-Houston.
Cancer metastasis, the spread of tumor to other parts of patient’s body, is responsible for over 90% of cancer death. However, it is still poorly understood and the current approaches to prevent or treat human metastatic diseases are largely unsuccessful. Through genomics, RNAi and cDNA functional screens, Dr. Li’s lab has identified several critical but previously unknown regulators for cancer metastasis. Signaling pathways and molecular mechanisms of these genes are in study with molecular, cellular, biochemical, genomic and proteomic approaches, genetic and xenograft mouse models, as well as cancer patient samples.
For example, Dr. Li’s lab is studying GRK3 (G protein-coupled receptor kinase 3), a kinase they identified from shRNA/cDNA screening, in the progression of CRPC (castration resistant prostate cancer), especially the highly metastatic variant of CRPC, the t-NEPC (treatment-related neuroendocrine prostate cancer). Specific inhibitors targeting some of these novel regulators have been or are being identified from molecular docking analyses (virtual screening with computer) or compound library screening on bench.
One group of exciting new cancer targets actively pursued in Dr. Li lab are cell surface or secreted proteins. Their roles and mechanisms in cancer progression are being investigated. Through collaborations with neighboring lab of Drs. Ningyan Zhang and Zhiqiang An, Director of Texas Therapeutics Institute, Dr. Li lab is discovering and characterizing novel antibodies as therapeutics candidates. Some of them will be further developed into other antibody-based therapies, such as antibody-drug conjugates (ADC), bio-specific antibody or CART cell therapy.
Another exciting research program in Dr. Li’s lab is involved in identifying and studying novel regulators of epithelial-mesenchymal transition (EMT). EMT, a developmental process, is believed to play a key role in drug resistance, organ fibrosis and cancer metastasis. Dr. Li’s lab was the first group to perform a kinome cDNA screening on EMT and has identified several new critical regulators of EMT. Investigations of the molecular mechanisms of these kinases have had a significant impact in expanding our knowledge in cancer progressing. Some of these kinases are being targeted by novel inhibitors.
