In one study, IRF2‐deficient mice treated with poly(I:C) develop acute pancreatitis that is linked to a dramatic, constitutive up‐regulation of trypsinogen5. Although the pancreatic inflammation requires type I interferon signaling and activation of dsRNA-sensing receptors such as MDA5, RIG-I, and TLR3, the sustained high expression of trypsinogen5 is independent of this pathway. This suggests that, once released from dying acinar cells, trypsinogen5 (which is resistant to the endogenous inhibitor Spink3) may trigger a self‐amplifying cascade of pancreatic injury."}, {"type": "fg", "children": [{"type": "fg_f", "ref": "1"}]}, {"type": "t", "text": "\n"}]}, {"type": "t", "text": "\n\n"}, {"type": "p", "children": [{"type": "t", "text": "\nIn the other studies, attention is focused on CDC23 (also known as cell division cycle 23), a core subunit of the anaphase promoting complex or cyclosome (APC/C). CDC23 localizes to the meiotic spindle in oocytes and is crucial for timely metaphase‐to‐anaphase transition. Knockdown or the presence of pathogenic missense variants in CDC23 disrupts spindle assembly checkpoint activity and inhibits the degradation of cyclin B1 and securin. This interference results in spindle abnormalities, misaligned chromosomes, errors in homologous chromosome segregation, and ultimately the production of aneuploid or maturation‐defective oocytes, which are linked to female infertility."}, {"type": "fg", "children": [{"type": "fg_f", "ref": "2"}]}, {"type": "t", "text": "\n"}]}, {"type": "t", "text": "\n\n"}, {"type": "p", "children": [{"type": "t", "text": "\nIt is important to note that none of these abstracts provide any insight into the function of CD99P1.
