Understanding the factors. which control ErbB2 and EGF receptor (EGFR) status in cells is likely to inform future therapeutic approaches directed at these potent oncogenes. ErbB2 is resistant to stimulus-induced degradation and high levels of over-expression can inhibit EGF receptor down-regulation. We now show that for HeLa cells expressing similar numbers of EGFR and ErbB2. https://safeersappliancers.shop/product-category/neff-c27cs22h0b-n90-built-in-60cm-a-electric-single-oven-stainless-steel/
