26634256 These data show that exposure to an allogeneic stimulus is not needed to cause a marked rise in PIBF, merely progesterone alone is sufficient.
25818991 Maternal serum progesterone-induced blocking factor (PIBF) in the prediction of preterm birth.
25218441 Progesterone-induced blocking factor is hormonally regulated in human astrocytoma cells, and increases their growth through the IL-4R/JAK1/STAT6 pathway
24474429 progesterone-induced blocking factor is intracellularly expressed by the cultured cells from Glioblastoma
24325791 reduced expression during late pregnancy and resorption
24225150 decreased kisspeptin and PIBF expressions in trophoblasts and deciduas are associated with recurrent spontaneous abortion
23807209 Data indicate that silencing of progesterone-induced blocking factor (PIBF) increased invasiveness as well as MMP-2,-9 secretion of HTR8/SVneo trophoblast, and decreased those of HT-1080 cells.
23110211 CEP90 physically interacts with PCM-1 at centriolar satellites, and this interaction is essential for centrosomal accumulation of the centriolar satellites and eventually for primary cilia formation.
22172828 Suggest that urinary PIBF levels may predict graft rejection in transplant recipients.
22032897 increased serum levels after dydrogesterone supplementation in women with threatened preterm delivery; positive correlation with the length of gestation
21632119 PIBF affects the expression of leptin and its receptor, and PIBF expression is inversely related to trophoblast invasiveness.
21224392 CEP90 was characterized as a component of pericentriolar satellites.
20367622 role of PIBF in both normal pregnancy and tumor biology [REVIEW]
19898481 Observational study of gene-disease association. (HuGE Navigator)
19371956 promotes secretion of type 2 cytkines by activated lymphocytes from pregnant woman
19290853 PIBF concentrations in urine and serum of patients with threatened abortion were significantly lower than in healthy pregnant women.
16433831 PIBF phosphorylates PKC via binding to the IL-4R, without affecting intracellular Ca(++). These findings explain the mechanism by which PIBF supports a Th2 dominant cytokine pattern.
15305375 progesterone induced blocking factor overexpression is associated with breast neoplasms
15269099 PIBF production is a characteristic feature of normal pregnancy, and determination of PIBF concentration in urine might be of use for the diagnosis of threatened premature pregnancy termination.
14634107 The 48-kDa N-terminal part of PIBF is biologically active, and the part of the molecule responsible for modulating natural killer cell activity is encoded by exons 2-4.
