L. crispatus, L. rhamnosus, L. gasseri, and L. jensenii supernatants reduce the expression of autophagy genes ATG14, BECN1, and cyclin A, cyclin-dependent kinase 2 (CDK2), and HPV E6 and E7 to inhibit cervical cancer cells activity (Motevaseli et al., 2016; Ghanavati et al., 2020). This evidence concerns the gene CDK2 and cervical cancer.
