Src homology region 2 (SH2) domain-containing phosphatase 1 (SHP-1, also known as PTPN6), a non-receptor protein tyrosine phosphatase (PTP), is predominantly expressed in haematopoietic and epithelial cell and widely accepted as a negative regulator of inflammation and as a tumour suppressor [13, 14]. This evidence concerns the gene NR0B2 and neoplasm.
