The tumor promoters 12-phorbol-13-myristate-acetate (PMA) and staurosporine or the anti-estrogen tamoxifen, H2O2 producing oxidative stress, leptin, IL-6 or staphylococcal endotoxin B, activin or anisomycin, did not significantly influence CCHCR1 mRNA levels (data not shown). Here, INHBE is linked to neoplasm.
