For example, deletion of Atg7 and Beclin1 inhibited autophagy induced by nutrient deprivation of cervical cancer cells and induced cell death (Yu et al., 2004) while stable knockdown of Atg7 in human breast cancer cells inhibited cell growth in soft agar and tumor formation in nude mice (Kim et al., 2011). The gene discussed is ATG7; the disease is cervical carcinoma.
