The invention belongs to the technical field of molecular biology and biomedicine and in particular relates to application of a gRNA (guide Ribonucleic Acid) sequence based on a CRISPR / Cas9 (Clustered Regularly Interspaced Short Palindromic Repeats / CRISPR associated protein 9) system on knockout of a human Lin28A gene and application to tumor treatment. According to a design principle of CRISPR / Cas9, 6 guide RNAs (gRNA) are designed and a sequence table is shown as SEQ ID NO.1 to SEQ ID NO.6; the guide RNAs are constructed on a PX458 carrier and two efficient target gRNAs are obtained through activity detection and screening. The CRISPR / Cas9 system guided by the two gRNAs is utilized in human hepatocellular carcinoma cell lines (HepG2) and human melanoma cell lines (A375), and the human Lin28A gene can be effectively knocked out; the system is easy to operate and the human Lin28A gene knockout efficiency is high, so that the system is applicable to various tumor cell models. The gRNA provided by the invention is hopefully applied to a new drug for treating tumors.

Autotaxin (ATX) is a prometastatic enzyme initially isolated from the conditioned media of human melanoma cells that stimulates a myriad of biological activities including angiogenesis and the promotion of cell growth, survival, and differentiation through the production of lysophosphatidic acid (LPA). ATX increases the aggressiveness and invasiveness of transformed cells, and ATX levels directly correlate with tumor stage and grade in several human malignancies. To study the role of ATX in the pathogenesis of malignant melanoma, we developed antibodies and small molecule inhibitors against recombinant human protein. Immunohistochemistry of paraffin embedded human tissue demonstrates that ATX levels are markedly increased in human primary and metastatic melanoma relative to benign nevi. Chemical screens identified several small molecule inhibitors with binding constants ranging from nanomolar to low micromolar. Cell migration and invasion assays with melanoma cell lines demonstrate that ATX markedly stimulates melanoma cell migration and invasion, an effect suppressed by ATX inhibitors. The migratory phenotype can be rescued by the addition of ATX's enzymatic product, LPA, confirming that the observed inhibition is linked to suppression of LPA production by ATX. Chemical analogues of the inhibitors demonstrate structure activity relationships important for ATX inhibition and indicate pathways for their optimization. These studies suggest that ATX is an approachable molecular target for the rational design of chemotherapeutic agents directed against human malignancies driven by the ATX / LPA axis, especially including malignant melanoma, among numerous others including breast and ovarian cancers.
