Example sentences for: tbx
How can you use “tbx” in a sentence? Here are some example sentences to help you improve your vocabulary:
Several genes expressed specifically in the normal male foreskin fibroblasts have been previously implicated in male genital development, including HOXA13 , the T-box genes, BMP4 and DWnt2 . Mutations in HOXA13 can cause distal limb and urogenital-tract malformations such as male hypospadias in hand-foot-genital syndrome [ 21 ] . T-box genes ( TBX ) are essential early regulators of limb development and also appear to be involved in male genital development [ 22 23 ] . Mutations in TBX3 cause the ulnar-mammary syndrome characterized by limb, apocrine, and genital developmental abnormalities [ 23 ] . Expression of T-box genes 2, 3, and 5 was significantly higher in normal male foreskin fibroblasts than in AIS genital fibroblasts.
TBX2 showed an almost identical expression profile to TBX3 , whereas high TBX5 expression appeared to be restricted to foreskin fibroblasts from normal males (including those from the phenotypically female mosaic patient ARD364).
Ectopic BMP4 can lead to the upregulation of Tbx5 in the retina, and Tbx5 misexpression results in altered retinal ganglion cell axon projections to the tectum [ 56 ] .
T-box gene 3 ( TBX3 ) was expressed at higher levels in the fibroblasts from genital skin, extragenital skin or prostate from males than in genital skin fibroblasts from AIS 46,XY females (Figure 2).
For instance, transcripts encoding homeobox A13 protein (HOXA13) and T-box proteins (TBX) showed striking differences in their expression levels between the 'male genital' and 'AIS/extragenital' fibroblasts.
