Expression levels of 6 diagnostic FRLs in umbilical cord blood lymphocytes from preterm infants and term infants. A Relative mRNA expression of LINC00348 in umbilical cord blood lymphocytes of preterm infants born before 32 weeks gestational age versus term infants. B Relative mRNA expression of LINC00691 in umbilical cord blood lymphocytes of preterm infants born before 32 weeks gestational age versus term infants. C Relative mRNA expression of LINC01003 in umbilical cord blood lymphocytes from preterm infants born before 32 weeks gestational age versus term infants. D Relative mRNA expression of POT1-AS1 in umbilical cord blood lymphocytes from preterm infants born before 32 weeks gestational age versus term infants. E Relative mRNA expression of PACRG-AS1 in umbilical cord blood lymphocytes from preterm infants born before 32 weeks gestational age versus term infants. F Relative mRNA expression of TTTY8 in umbilical cord blood lymphocytes from preterm infants born before 32 weeks gestational age versus term infants. G Relative mRNA expression of LINC00348, LINC00691, LINC01003, POT1-AS1, PACRG-AS1, TTTY8 in umbilical cord blood lymphocytes from preterm infants with BPD versus preterm infants without BPD. All data throughout the figure was presented as mean ± SEM (n = 3 to 20). Statistical comparison by unpaired t-test, * p < 0.05, ** p < 0.01, ns = no significance
