Ankle sprains are a common injury. According to the National Electronic Injury Surveillance System (NEISS), an estimated 630,891 ankle sprains occurred in 2009 (CPSC, 2011). The anterior talofibular ligament (AFTL) is frequently sprained as a result of a plantarflexion-inversion injury.

Calcium influx through L-type voltage-gated calcium channels (VGCC) is required for ERK activation induced by GnRH in pituitary gonadotropes. The current studies investigate VGCC-sensitive catalytic activities that may lie upstream of ERKs within the GnRH signaling network. Ion exchange fractionation of alphaT3-1 cell lysates subjected to anti-phosphotyrosine Western blot analysis revealed a nifedipine-sensitive activity that colocalized with proline-rich tyrosine kinase (Pyk) 2 immunoreactivity.

Dlx3, a homeodomain transcription factor, is essential for placental development in the mouse. The Dlx3(-/-) mouse embryo dies at embryonic d 9.5-10 putatively due to placental failure.

Dlx3 (Distal-less 3) is a homeobox-containing transcription factor required for normal placental development in mice. Here we demonstrate that Dlx3 interacts with Smad6, a member of a larger family of transcriptional regulators generally thought to regulate transforming growth factor beta/bone morphogenetic protein signaling. Immunocytochemical and immunoprecipitation studies demonstrate overlapping nuclear localization and physical interaction between Dlx3 and Smad6 in human choriocarcinoma cells and in differentiated trophoblasts from human placenta.

Distal-less 3 (Dlx3) is a homeobox factor that functions as a placental-specific transcriptional regulator. Dlx3 null mice (-/-) have compromised placental development and do not survive in utero past embryonic day (E) 9.5.
