LGR5 and endometrial cancer: These include studying the role of Wnt signalling and Lgr5+ cells in the murine endometrium for endometrial regeneration (Seishima et al., 2019); advancing models to study the pathogenic colonization mechanisms of Chlamydia trachomatis infections in the endometrial epithelia (Bishop et al., 2020; Dolat and Valdivia, 2021); and investigating the role of KRAS mutations in endometrial cancer development (Maru et al., 2019; 2021).
