Microarray results showed that TPT significantly increased expression of 958 genes and decreased expression of 1400 genes in THP-1 cells upon LPS stimulation.
In conclusion, ZLN and TPT treatments are safe on carotid walls in osteoporotic women with subclinical atherosclerosis; circulating OPG and OPN are not affected by long-term anti-osteoporotic treatments and do not correlate with CA-IMT.

Triphalangeal thumb‑polysyndactyly syndrome (TPT‑PS) is an autosomal dominant disorder with complete penetrance and a variable expression consisting of opposable triphalangeal thumbs, duplication of the distal thumb phalanx, pre‑axial polydactyly and duplication of the big toes (hallux).

Although most mutations cause preaxial polydactyly (PPD), triphalangeal thumb (TPT) or both, a mutation in position 404 of the ZRS causes more severe Werner mesomelic syndrome (WMS) for which malformations include the distal arm or leg bones in addition to the hands and/or feet.
Point mutations and duplications of the ZRS lead to a variable phenotype of preaxial polydactyly/triphalangeal thumb, tibial hypoplasia, radial ray deficiency, and type IV familial syndactyly (syndactyly of all digits with polydactyly).
A locus for triphalangeal thumb, variably associated with pre-axial polydactyly, was previously identified in the zone of polarizing activity regulatory sequence (ZRS), a long range limb-specific enhancer of the Sonic Hedgehog (SHH) gene at human chromosome 7q36.3.
We found this variant in three independently ascertained probands from southern England with triphalangeal thumb, demonstrated significant linkage of the phenotype to the variant (LOD = 4.1), and identified a shared microsatellite haplotype around the ZRS, suggesting that the probands share a common ancestor.
With respect to gender, 7/12 (58%) of mapped SHFM3 cases with TPT/split foot were male whereas 5/12 (42%) were female, compared with 22/50 (44%) males and 28/50 (56%) females among unmapped cases (P=0.3715).
Preaxial involvement of the upper extremities was most commonly seen at the SHFM3 locus mapped to chromosome 10q24 (OMIM 600095) and consisted of proximally placed thumbs and/or triphalangeal thumbs (TPT), preaxial polydactyly and/or absence of the first ray.
In a previous report, we described the clinical and radiographical features of three related subjects with the disease and suggest that due to the unusual combination of limb defects and to its phenotypic similarity with the limb malformative pattern induced by disrupting the Hoxd13 gene in mouse, the triphalangeal thumb-brachyectrodactyly syndrome might be caused by mutations in a HOX gene.
