the molecular mechanisms by which PTP1B (show PTPN1 Proteins) and TC-PTP loss co-operates with other genetic aberrations will need to be elucidated to design more effective therapeutic strategies.
In summary, we demonstrate that TCPTP protects the intestinal epithelial barrier by restricting STAT (show STAT1 Proteins)-induced claudin-2 (show CLDN2 Proteins) expression.
PASD1 (show PASD1 Proteins) serves as a critical nuclear positive regulator of STAT3 (show STAT3 Proteins)-mediated gene expression and tumorigenesis.
reported that SNPs in STAT4 (show STAT4 Proteins), PTPN2, PSORS1C1 (show PSORS1C1 Proteins), and TRAF3IP2 (show TRAF3IP2 Proteins) are associated with response to TNF (show TNF Proteins)-i treatment in RA patients; however, these findings should be validated in a larger population
The results suggest that miR (show MLXIP Proteins)-448 might promote Th17 differentiation in multiple sclerosis and thus aggravate the disease through inhibiting PTPN2.
ACPA (show PRTN3 Proteins) were associated significantly with rs7574865 in STAT-4 (show STAT4 Proteins). The SNP rs2233945 in the PSORS1C1 (show PSORS1C1 Proteins) gene was protective regarding the presence of bone erosions, while rs2542151 in PTPN2 gene was associated with joint damage.
Inflammatory bowel disease patients carrying the C-allele of PTPN2 SNP rs1893217 are at greater risk for developing a severe disease course but are more likely to respond to treatment with anti-TNF (show TNF Proteins) antibodies.
The increase in miR (show MLXIP Proteins)-210 resulted in down regulation of its target PTPN2 mRNA in pre-eclampsia.
role of PTPN2 in type 1 diabetes and Crohn's disease (review)
rs2542151 SNP in The PTPN2 gene is associated with T1DM in Chinese Han children
PTPN2 overexpression in white adipose tissue could significantly reduce macrophages infiltration, the ratio of M1/M2 macrophages and the expression of pro-inflammatory cytokines in white adipose tissue , improving insulin (show INS Proteins) resistance.
Data suggest that interaction of Ppard (show PPARD Proteins) with Tcptp45 blunts insulin (show INS Proteins) resistance and leads to retention of Tcptp45 in nucleus of hepatocytes, myotubes, and adipocytes; alteration of such interactions may be involved in insulin (show INS Proteins) resistance observed in obesity. (Ppard (show PPARD Proteins) = peroxisome proliferator activator receptor delta (show PPARD Proteins); Tcptp45 = protein tyrosine phosphatase non-receptor type 2 [Ptpn2], 45kDa (show NFE2 Proteins) alternative splicing variant)
These results indicate that deficiencies in PTPN2 across multiple immune lineages, including naive T cells, Tfh cells and B cells, contribute to the development of autoimmunity.
PTPN2 is a positive regulator of lipopolysaccharide-induced inflammatory response by enhancing the activity of Src (show SRC Proteins) through targeting the inhibitory phosphor-tyrosine527 of Src (show SRC Proteins).
Loss of PTPN2 in intestinal epithelial cells has no significant influence on inflammation in dextran sulphate sodium-induced colitis. On the other hand, loss of PTPN2 induced enhanced epithelial cell proliferation and promoted wound closure.
Antigen receptor-mediated depletion of FOXP3 (show FOXP3 Proteins) in induced regulatory T-lymphocytes via PTPN2 and FOXO1 (show FOXO1 Proteins)
A novel role for TCPTP in insulin (show INS Proteins) secretion and uncover STAT3 (show STAT3 Proteins) as a physiologically relevant target for TCPTP in the endocrine pancreas.
dysfunction of PTPN2 results in aberrant T-cell differentiation and intestinal dysbiosis similar to those observed in human CD. Our findings indicate a novel and crucial role for PTPN2 in chronic intestinal inflammation.
PTPN2 attenuates T-cell lymphopenia-induced proliferation.
demonstrate that SIPAR (show FAM220A Proteins) directly interacts with T cell protein tyrosine phosphatase TC45 and enhances its association with STAT3 (show STAT3 Proteins)
The protein encoded by this gene is a member of the protein tyrosine phosphatase (PTP) family. Members of the PTP family share a highly conserved catalytic motif, which is essential for the catalytic activity. PTPs are known to be signaling molecules that regulate a variety of cellular processes including cell growth, differentiation, mitotic cycle, and oncogenic transformation. Epidermal growth factor receptor and the adaptor protein Shc were reported to be substrates of this PTP, which suggested the roles in growth factor mediated cell signaling. Multiple alternatively spliced transcript variants encoding different isoforms have been found. Two highly related but distinctly processed pseudogenes that localize to chromosomes 1 and 13, respectively, have been reported.
