Because autophagy promotes primary ciliogenesis, we next explored whether breast cancer cells lacking STARD7 undergo autophagy.[35] We first noticed that multiple lysosomal candidates such as Niemann‐Pick C2 protein (NPC2), N‐acetyl‐alpha‐glucosaminidase (NAGLU) and Lysosomal‐associated membrane protein 1 (LAMP1) were enriched at the mRNA level in MCF7 cells lacking STARD7 (Figure10A). Here, LAMP1 is linked to breast cancer.
