  3. REVIEW: structural basis and recent research progression on SHP2 in various human disease, including genetic and cancer diseases. PMID: 27028808
  4. the tumor promoting role of YAP is involved in SHP2 which functions as a tumor promoter in vitro but as a tumor suppressor in vivo PMID: 29699904
  5. Data indicate that by inhibiting adenine nucleotide translocase 1 (ANT1) and mitochondrial dysfunction, tyrosine phosphatase SHP2 orchestrates an intrinsic regulatory loop to limit excessive NLR family, pyrin domain-containing 3 protein (NLRP3) inflammasome activation. PMID: 29255148
