A handful of studies utilized various stimuli known to induce TAp73 expression, including DNA-damaging conditions such as irradiation, etoposide, doxorubicin, and cisplatin treatment [28,40,41,42,43], or tumor-promoting conditions such as hypoxia [29,44,45,46], tumor necrosis factor (TNFα) treatment [47], and serum stimulation [48]. Here, TNF is linked to neoplasm.
