Autophagy can serve as a tumor suppressor, as a partial reduction in autophagic capacity or defective autophagy (e.g., heterozygous knockdown BECN1 (+/-) in mice) provides an oncogenic stimulus, causing malignant transformation and spontaneous tumors.

The mRNA and protein expressions of Beclin1 and Bcl-2 in breast cancer tissues were significantly lower than those in the relatively healthy, adjacent breast tissues (p < 0.05); the lower the degree of tumor differentiation, the lower the mRNA and protein expressions of Beclin1 and Bcl-2 (p < 0.05); the mRNA and protein expressions of Beclin1 and Bcl-2 in breast cancer tissues from patients positive for lymph node metastasis were significantly lower than those negative for lymph node metastasis (p < 0.05); the mRNA and protein expressions of Beclin1 and Bcl-2 in breast cancer tissues from patients positive for distant metastasis were significantly lower than those negative for distant metastasis (p < 0.05); the mRNA and protein expressions of Beclin1 and Bcl-2 in breast cancer tissues from patients positive for ki67 were significantly lower than those negative for ki67 (p < 0.05).
