microRNAs have been established as powerful regulators of gene expression in normal physiological as well as in pathological conditions, including cancer progression and metastasis. Recent studies have demonstrated a key role of miR-31 in the progression and metastasis of breast cancer. Downregulation of miR-31 enhances several steps of the invasion-metastasis cascade in breast cancer, i.e., local invasion, extravasation and survival in the circulation system, and metastatic colonization of distant sites. miR-31 exerts its metastasis-suppressor activity by targeting a cohort of pro-metastatic genes, including RhoA and WAVE3. The molecular mechanisms that lead to the loss of miR-31 and the activation of its pro-metastatic target genes during these specific steps of the invasion-metastasis cascade are however unknown.

Laboratory portal that houses the following databases. MethPrimer is a program for designing bisulfite-conversion-based Methylation PCR Primers. Currently, it can design primers for two types of bisulfite PCR: 1) Methylation-Specific PCR (MSP) and 2) Bisulfite-Sequencing PCR (BSP) or Bisulfite-Restriction PCR. CpG Island Prediction MethPrimer can also analyze input sequences for the existence of CpG islands. Human Prostate Gene Database (PGDB) is a curated and integrated database of human genes related to the prostate and prostatic diseases. Human Kidney Gene Database (KGDB) is a curated and integrated database of human genes related to the kidney and renal diseases. The Li Lab is interested in understanding how small RNA regulates gene expression at the transcriptional level by targeting gene promoter sequences, particularly how small RNA activates gene transcription, a phenomenon termed RNA activation (RNAa).
