| ABSTRACT
Introduction: There is a high expression of receptor tyrosine kinase like orphan receptor-1 (ROR-1),
a tyrosine kinase receptor, in various tumor-cell types. ROR-1 is involved in many key processes in
cancer including proliferation, survival and metastasis. Hence, ROR-1 is an attractive and promising
therapeutic target. There are many therapeutic approaches that target ROR-1 and these include specific
monoclonal antibodies (mAbs), modified T cells (CART cell), miRNAs and tyrosine kinase inhibitors (TKI).
Areas covered: This review examines ROR-1 structure and function, immunotherapeutic strategies
including specific chimeric antigen receptor (CARs) T cells and miRNAs and other targeted approaches
such as the use of tyrosine kinase inhibitors.
Expert opinion: Chimeric antibodies, CARs T cells, bi-specific T cell engagers (BiTEs), miRNAs and TKIs
are used to target the ROR-1 marker on cancer cell lines. By selecting the most favorable therapeutic
approaches regarding ROR-1 in vivo, anti-ROR-1 antibodies or CAR T cells can be also used for diagnosis
of ROR-1+ cancer cells in new technologies such as biosensors. Moreover, ROR-1 targeted combination
therapy with other cancer biomarkers could be considered a novel therapeutic strategy for cancer
treatment. |
