PAC1 deficiency reduces chondrogenesis in atherosclerotic lesions of hypercholesterolemic ApoE-deficient mice.

Interfering with Dusp2 alleviates high glucose-induced vascular endothelial cell dysfunction by promoting p38 MAPK pathway activation.
Title: Interfering with Dusp2 alleviates high glucose-induced vascular endothelial cell dysfunction by promoting p38 MAPK pathway activation.
Deletion of PAC1 enhances immune responses and reduces cancer susceptibility in mice. Through activation of EGR1, excessive reactive oxygen species in the tumor microenvironment induce expression of PAC1, which recruits the Mi-2beta nucleosome-remodeling and histone-deacetylase complex, eventually leading to chromatin remodeling of effector T cells.
Title: The phosphatase PAC1 acts as a T cell suppressor and attenuates host antitumor immunity.

Data indicate that dual specificity phosphatase 2 protein (DUSP2) is a true STAT3 transcription factor phosphatase that modulates the development of TH17 cells in the autoimmune response and inflammation.
Title: The phosphatase DUSP2 controls the activity of the transcription activator STAT3 and regulates TH17 differentiation.
DUSP2 plays no role in regulating obesity-associated inflammation and only a minor role in controlling insulin sensitivity following high-fat diet in female, but not male, mice.
Title: The dual-specificity phosphatase 2 (DUSP2) does not regulate obesity-associated inflammation or insulin resistance in mice.
the expression of PAC1 in the thymus changes in reverse ratio with thymus index and in direct ratio with cell apoptosis and only low dose of PACAP had positive effects against the CPS-induced thymus atrophy.
Title: The expression of PAC1 increases in the degenerative thymus and low dose PACAP protects female mice from cyclophosphamide induced thymus atrophy.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
