The fact that the high eEF1A1 levels in tumour tissue and cancer cells are not accompanied by an increase in eEF1A1 mRNA levels may be related to the fact that the eEF1A1 protein has a long half-life; similar observations have been made for the ubiquitin-like protein FAT10 in cancer cells [29]. The gene discussed is EEF1A1; the disease is neoplasm.
