In the case of GPS2-GPS2P1 there is clear evidence that the protein is expressed in normal breast tissue, that GPS2 and GPS2P1 are positively correlated in tumor samples (i.e., positive correlation is indicative of ceRNA interaction), there is evidence of miRNA targeting GPS2, and there are external experimental findings showing GPS2 miRNA regulation causes breast cancer cell proliferation by reducing GPS2 protein levels. The gene discussed is GPS2P1; the disease is breast carcinoma.
