PLA2G3 and breast carcinoma: This finding appeared relevant to us given the fact that the primary cilium is assembled in the G0/G1 phase in which breast cancer cells accumulate upon STARD7 deficiency.[34] Real‐Time PCR analyses indeed confirmed that WDR19, DNAH1, DNAAF4, IFT22/43, and CFAP69 were more strongly expressed at the mRNA level in STARD7‐depleted MCF7, T47D, or MDA‐MB231 cells, while mRNA levels of PLA2G3, a negative regulator of ciliogenesis were down (Figure 9D and Figure S6, Supporting Information).
