| Popis: | Surfactant protein (SP) C has been shown to be expressed also outside pulmonary alveoli. Certain SP-C gene (SFTPC) polymorphisms associate with lung diseases and very preterm birth.We investigated the association of SFTPC single nucleotide polymorphism (SNP) rs4715 with factors affecting spontaneous preterm birth and characterized the SP-C expression in human and mouse gestational tissues.The SFTPC SNP rs4715 polymorphism was genotyped in a homogeneous northern European population of mothers and infants in spontaneous preterm birth and term controls. The expression and protein of SP-C in gestational tissues was analyzed.SFTPC SNP rs4715 did not associate with spontaneous preterm birth. However, fetuses with short interval (72 hours) between preterm premature rupture of fetal membranes (PPROM) and preterm birth had significant over-representation of the minor allele A, whereas in fetuses with prolonged PPROM (or=72 hours) the frequency was decreased. Maternal SFTPC did not associate with the duration of PPROM. SP-C mRNA and proprotein were detected in fetal membranes, placenta, and pregnant uterus.SFTPC SNP rs4715 associates with the duration of PPROM, and SP-C is expressed in gestational tissues. We propose that fetal SFTPC moderates the inflammatory activation within the fetal extra-embryonic compartment. |
