The group 2 pattern (normal segments at 4 months but WT below the normal limit at 24 months) was seen in 28 segments (WT 3.8 ± 0.7 mm and 1.8 ± 0.9 mm at 4 and 24 months, respectively) in 16 patients.
The group 1 pattern (normal segments at both time-points) was seen in 183 segments (WT 5.0 ± 1.4 mm and 5.6 ± 1.7 mm at 4 and 24 months, respectively) in 21 patients.
Conversion of the band into frequency space provides a pattern, segments of which can act as a template to be extracted from the frequency spectrum of the original data set.
Together these observations suggest that during pupation, as during embryogenesis, tsh functions cooperatively with trunk-specific Hox genes to pattern segments of the adult abdomen.
The best-known targets of these proteins are the Hox genes, transcription factors important for anterior-posterior patterning, segment identity, and hematopoiesis.
When datapoints showed two different distribution patterns, segmented linear regressions and breakpoints were calculated using the software SegReg (R. J. Oosterbaan, Wageningen, The Netherlands).
Ubx promotes reduced A1 tergite size and unique bristle morphology as well as repressed A1 sternite development while Abd-A principally patterns segments A2 A4, which have similar morphology to one another (Duncan, 1987; Lewis, 1978).
