Despite several investigations, the transcriptional mechanisms that regulate the expression of both type I collagen genes (COL1A1 and COL1A2) in either physiological or pathological situations, such as scleroderma, are not completely known. We have investigated the role of hc-Krox transcription factor on type I collagen expression by human dermal fibroblasts. hc-Krox exerted a stimulating effect on type I collagen protein synthesis and enhanced the corresponding mRNA steady-state levels of COL1A1 and COL1A2 in foreskin fibroblasts (FF), adult normal fibroblasts (ANF), and scleroderma fibroblasts (SF). Forced hc-Krox expression was found to up-regulate COL1A1 transcription through a -112/-61-bp sequence in FF, ANF, …

Aicardi syndrome is a rare X-linked dominant genetic disorder characterized by infantile spasms, agenesis or hypogenesis of the corpus callosum, and chorioretinal lacunae. There remain many unresolved questions regarding the clinical features of this disorder. Recent advancements in neuroimaging techniques have allowed us to obtain information about brain development and perfusion. Thus, we present herein the brain single-photon emission computed tomography (SPECT) findings in a 15-month-old female with Aicardi syndrome, which revealed that perfusion had shifted from the posterior to anterior regions. Furthermore, the right temporal lobe was not visualized, while significant hypoperfusion was determined on the occipital regions and …
