In human, there were also decreased expressions of ATG5, ATG7, BECN1 and MAPLC3B in PF from EMs patients, and silencing HCK led to the up‐regulation of ATG5, BECN1 and LC3B, and the down‐regulation of P62 in THP1 cells (Figure 5C–E). The gene discussed is BECN1; the disease is eosinophilia-myalgia syndrome.
